Samsung unveil Galaxy Fold

Thursday, February 21st 2019

Samsung officially unveiled their highly anticipated foldable smartphone, the Galaxy Fold, yesterday at its Unpacked event in San Francisco. The South Korean technology giant’s debut foldable device features their in-house 7.3-inch ‘Infinity Flex Display’ and was described as being capable of seamlessly transitioning between a smartphone, tablet and camera. The device is planned to go on sale in just over two months’ time.

The Galaxy Fold marks the arrival of a new ultra-premium market segment, described as a luxury item by Samsung. The initial 4G version of will start at $1,980 (£1,515), with a 5G version planned for future release. David Lee, BBC’s North America technology reporter, cited the Fold as a ‘tremendously creative feat of engineering’.

Samsung have designed a novel display for the Galaxy Fold, around 50% thinner than existing smartphone displays. However the Verge observe the relatively thick nature of the folded device. CML has previously reported that future folding devices are expected to be developed with a slimmer form factor to be closer in thickness to handsets available currently.

The Galaxy Fold sports cameras on all three device ‘faces’ to ensure it can capture images however it is held. Therefore, the smartphone arrives with a total of six cameras. This provides a positive outlook for high end camera component suppliers such as CML, as the number of cameras per device continues to grow, especially for high-end devices.

Consumer Electronics Show 2019

Friday, January 18th 2019

The Consumer Electronics Show, CES, is the world’s largest consumer electronics trade show and was held this month in Las Vegas. It attracts technology leaders and pioneers from across the world. Over 182,000 visitors, 4,400 exhibitors and 1,000 speakers attended this immense display of innovation. A multitude of exciting products were on display varying from walking cars, to wooden smart speakers.

As reported by the BBC, curved and foldable displays were a key topic of CES 2019. LG’s roll-up TV, the LG Signature OLED TV R, impressed with T3 describing the product as a ‘true game-changer’. The television and components are made of a flexible material which allows compact storage within a box, unrolling upwards when required. Royole’s Flexpai, the world’s first smartphone with a foldable screen, was also on display alongside an array of concepts showcasing the company’s technology. The Flexpai unfolds into a tablet configuration with a 7.8 inch diagonal screen size and can fit inside a pocket when folded up.

CML are monitoring foldable display technology with anticipation. The first folding handsets released by Royole, and expected later this year from Samsung and Huawei, are reported to be quite thick. However, CML expect users to demand that over time these devices should be be no thicker than current smartphones. This will apply significant pressure to the thickness of key device components. The design of our SMA camera and haptic actuators are significantly thinner than those using alternative technologies, allowing future foldable devices to ship with advanced feature sets and still achieve slimmer designs.

Samsung’s Foldable Smartphone

Thursday, November 8th 2018

Yesterday Samsung unveiled more details of their highly anticipated foldable smartphone in San Francisco at the Samsung Developer Conference. It features a folding screen, the Infinity Flex Display, as the South Korean company moves closer to launching a device in this format.

With dimmed lights, Justin Denison, SVP of mobile product marketing, briefly showcased the foldable smartphone. Likely to fuel anticipation from early adopters, this device is not the finished article and the development process has been extremely complicated. However, Samsung advise it will be ready to mass produce the device ‘in the coming months’.

The announcement leaves ambiguity surrounding the final device look, however, first impressions indicate it will be thicker than smartphones currently on the market. We expect users will demand folding smartphones to adopt increasingly slimmer designs in future models with the eventual aim to produce a folded device no thicker than competing non-foldable smartphones. Due to the format of this device, the unfolded device should be half the thickness of smartphones currently on the market to ensure the folded version remains dimensionally viable. This will require thinner cameras to prevent camera-shaped protrusions, which in turn favours technology miniaturising the camera module. One of the many benefits of utilising CML’s SMA technology includes the ability to reduce camera dimensions, particularly thickness, allowing slimmer folding handsets without unsightly camera bulges.

Image Sensor Market Set to Boom

Friday, October 19th 2018

Industry sources report that leading CMOS image sensor (CIS) maker Sony has expanded its capacity in anticipation of a boom in CIS demand in 2019. It is expected that the 2019 demand will be fuelled in part by an increase in adoption of triple cameras, a topic that has previously been covered by CML’s Marketing Director Dominic Webber.

The anticipated increase in CIS demand is consistent with a recent CIS market report by analyst Yole Développement. Yole forecasts that the CIS market will enjoy a 9.4% CAGR between 2017 and 2023, which it says will be “driven mainly by smartphones integrating additional cameras”.

At its simplest level, CML expects that the integration of more camera modules into smartphones will lead to an increase in the size of the smartphone camera actuator market. CML expects that additional implications of adding more camera modules to smartphones include increasing pressure on camera size and furthering the issue of magnetic interference caused by placing multiple VCM actuators in close proximity. CML believes that its platform SMA technology is well suited to the multiple camera trend given that it is an intrinsically small, non-magnetic technology.

Apple confirms commitment to 3D sensing

Thursday, September 13th 2018

By Dominic Webber, CML’s Marketing Director

During Apple’s Special Event yesterday, three new iPhone models were launched: the XS, XS Max and XR. During the event, particular emphasis was made to mark a shift to ever-larger screens. The sizes of the new models are 5.8”, 6.5” and 6.1” respectively.

Another major advance was that all of the new iPhones will come equipped with a front-facing 3D sensing module to provide ‘Face ID’, Apple’s 3D face recognition technology. This was first launched last year, but only available on the flagship iPhoneX device. The iPhone8 and 8Plus use a fingerprint sensor underneath the home button to unlock the phone instead.

Both Xiaomi and Oppo launched smartphones this year with similar 3D face recognition technology in their Mi8 Explore Edition and Oppo FindX handsets. Oppo launched a further device, the R17 Pro, which uses 3D sensing in the back face of the phone to create depth data of the surrounding scene.

This reinforces CML’s expectation that 3D sensing modules will eventually be broadly adopted by smartphones, although initially led by top-end devices. As is the case for cameras, we anticipate strong demand for ongoing performance and specification improvements for new applications and an enhanced user experience. Therefore, CML is making available products to deliver advanced, next generation 3D sensing modules for both the front and rear of smartphones using its SMA smart material platform technology.

Smartphone Camera Module Maker Experiences Margin Squeeze

Monday, August 20th 2018

Major producers of smartphone compact camera modules recently announced their interim results for the first half of 2018. Of particular interest was Sunny Optical’s announcement. Sunny Optical is one of the world’s largest producers of compact camera modules, which make up 77% of the company’s overall revenues. Although Sunny’s camera module business segment experienced revenue growth of 14.6% compared to H1 2017, it suffered a fall in gross margin from 12.7% to 9.4% in the same period.

Post release of their H1 2018 results, Sunny have experienced a 28% reduction in their share price. Analysts report that the main driver of the poor results was a squeeze on margins caused largely by rising component costs. Around 50% of Sunny’s cost of sales are imported. For high end camera modules, key components including lens actuators and image sensors are typically imported from Japanese and Korean companies. The weakness of Renminbi in the first half of 2018 has contributed to the rising component costs.

CML’s SMA actuator products are simpler to manufacture than the incumbent VCM technology, whose largest suppliers are from Japan and Korea. As a result CML has been successful in establishing partnerships and licence agreements with Chinese actuator makers. This has allowed them to expand their product offering, particularly with respect to OIS actuators, and offer domestic supply chains for Chinese compact camera module makers.

Allowing Chinese suppliers to provide high end lens actuators offers protection to Chinese supply chains from unpredictable exchange rate volatility and their impact on financial performance. CML considers this a further substantial benefit from a licence to its SMA technology, in addition to the miniaturisation and performance advantages.

Huawei Moves Into Second Position

Monday, August 6th 2018

According to reports from IDC and Canalys, Huawei have surpassed Apple to move into second position based on global market share of smartphone handset sales. Huawei’s market share increased to 15.8% – a record high for the company – as it delivered shipments of 54 million units in 2Q18. This represents an impressive year-on-year growth of 40.9%.

Huawei’s volume growth has been driven by a combination of strong performance of its latest flagships – the P20 and P20 Pro – and increased sales outside China of its mid-to-low tier Honor branded smartphones. At the flagship end Huawei has accelerated its adoption of new technologies, particularly regarding imaging with the P20 Pro featuring the world’s first triple camera.

The report by IDC also shows growth for the other leading Chinese smartphone vendors, with Xiaomi experiencing a 48.8% year-on-year growth. CML expects that the leading Chinese smartphone vendors will continue to consolidate their positions and display year-on-year growth. CML has been successful in growing its activity with Chinese handset vendors, camera integrators and actuator makers. CML is set to benefit from the increased interest from the Chinese supply chain for smartphone cameras.

The Triple Camera Trend

Wednesday, July 18th 2018

By Dominic Webber, CML’s Marketing Director

Sharp and Samsung released the first camera phones in 2000 with 0.11 Megapixels and 0.35 Megapixels respectively. The Sony Ericsson Z1010 was the first selfie camera phone, launched in 2003 with 0.3 Megapixels. Over time, sensor resolutions continued to steadily rise – 2, 3, 5 and 8 Megapixels – with the Nokia Pureview 808 hitting 41 Megapixels in 2012. Autofocus (AF) functionality is now included in almost all smartphones and Optical Image Stabilisation (OIS) features in premium models by the major brands.

The first dual camera phone was introduced by hTC in their Evo 3D model in 2011. Dual cameras have been added to both premium and mainstream devices by almost all major smartphone brands, including dual selfie cameras. Their popularity is driven by the ability to deliver enhanced image quality and new features, such as genuine optical zoom, Bokeh for background blurring in portraits, and 3D mapping for applications such as Augmented Reality.

Huawei’s P20 Pro contains the first triple camera, and the technical media reports rumours that the other top two brands, Samsung and Apple, will release triple camera handsets next year. Therefore it is expected that the whole industry will follow suit in time. Some industry players are now beginning to talk about quad cameras.

A consequence of adding more camera modules to a compact area is that the issue of magnetic interference with other components becomes more prevalent. The current actuator technology, voice coil motor, uses magnets to generate a driving force. CML’s shape memory alloy (SMA) actuator technology does not contain magnets and therefore does not interfere with other key smartphone components.

A further implication of using dual, triple, or even quad cameras is that they increase the size of the much bemoaned camera bump. I recently posted an article explaining how CML’s actuator technology can significantly reduce camera thickness, which could potentially allow smartphone vendors to remove the unsightly and impractical camera bump.

Triple cameras could rise in popularity at a similar rate to that experienced by dual cameras and, although we may need to wait until 2019 to see whether triple cameras take hold, it appears as though the trend to add more cameras to smartphones has yet to reach a limit – which is good news for CML.

MWC Shanghai Round Up

Wednesday, July 4th 2018

We were pleased to be invited to be a speaker at MWC Shanghai 2018 last week. It was, as always, interesting to witness cutting edge mobile technologies in action. Although the future of 5G was the dominant topic at the event, there were also some imaging developments that were noteworthy.

Interest in 3D sensing, and its application in smartphones, continues to intensify with Vivo demonstrating its Time of Flight 3D sensing technology. The technology features industry-leading performance with regards to the depth of information that it captures from its subject, which improves the accuracy of the 3D model. Vivo also claim that their technology can enable 3D mapping at a distance of up to three meters from the phone. These enhancements, coupled with AI technology, open up the potential for a broader application of 3D sensing beyond facial recognition, including using full-body scans to try on clothes virtually and 3D modelling.

CML believes there will be continued demand for increasingly sophisticated 3D sensing technologies and is developing new solutions which will improve the resolution of 3D sensing modules.

Imaging technology was also central and addressed in the speaker session of Li Changzhu, Vice President of Handset Business for Huawei Consumer Business Group. Mr. Changzhu highlighted the importance of AI to deliver the high image quality seen in Huawei’s P20 and P20 Pro handsets. He added that camera improvements continue to be key for Huawei and that their vision is to deliver the performance of a professional camera in a mobile phone.

At CML we are conscious of the need and desire to continue to improve camera quality. We have accordingly optimised our actuators to provide the enhancements that the market demands.

Pop-Up Cameras

Friday, June 22nd 2018

By Dominic Webber, CML’s Marketing Director

There is a constant drive by the major smartphone brands to maximise the size of the display without increasing the overall height and width of the handset, so that the phone is practical to handle and carry around. Bezel-less displays are becoming a key differentiator of premium smartphones. However, as the display size increases and bezels become smaller or disappear entirely, smartphone manufacturers need to determine  where to place the ‘selfie camera’, which usually appears above the display.

Many brands have added ‘notches’ to the top of the display to house the camera while  still providing useful display area either side of the notch. Xiaomi, with their Mix2 smartphone, moved the selfie camera from the top bezel to the bottom one. In handsets recently launched by Vivo and Oppo, a novel alternative approach has been revealed, called ‘pop-up’ cameras.

Vivo’s Nex selfie camera rises in a block-shaped frame when the camera is activated, and retracts back into the handset when not in use. The Oppo Find X selfie camera slides up from inside a wide section of the handset body. Many websites are inviting consumers’ opinions on their preference. This is likely to be quite a personal view due to the various pros and cons. However, one aspect that both designs have in common is that pop-up cameras move the camera bulk and launch mechanism elsewhere, increasing the overall handset thickness. Both the Nex and Find X handsets are around fifteen percent thicker than the manufacturers’ other premium range models, despite slim handsets being a popular requirement for high-end products.

The pop-up camera cannot use the current approach of bump-outs in the casework to allow for relatively thick cameras that are built using conventional optics and actuator technology. The pop-up mechanism simply wouldn’t work, it would be stuck in the casework. As described in a recent article I posted, CML’s technology can significantly reduce camera thickness, allowing a pop-up mechanism without compromising the handset thickness and styling. So we will watch with interest whether the pop-up camera becomes a long-term trend, and to determine its impact on the ongoing drive for ever thinner cameras.

How to Remove the Annoying Camera Bump from Smartphones

Wednesday, June 6th 2018

By Dominic Webber, CML’s Marketing Director

An interesting piece from Mashable on the ‘bump’ in smartphones caused by the thickness of most cameras.

The bump is not just aesthetically displeasing, but also gives rise to practical issues – for instance when the handset is on a flat surface, such as a desk or table, this causes the phone to rock as you touch the screen to type or navigate, causing errors and irritation.

So why is there a bump in the first place? It arises from the competing consumer demand for slim handsets on the one hand and improved camera quality on the other. In order to deliver upgraded camera specifications, larger components are necessary such as image sensors with more megapixels, lenses with larger apertures and lens actuators with greater driving power and axes of motion.

At CML we recognise that the camera bump is a key issue for smartphone designers in this highly competitive market. So CML has leveraged its shape memory alloy (SMA) platform technology to address this industry issue.

The camera bump arises from two factors – firstly, the thickness of the actuator that moves the lens to keep the image in focus and remove blur caused by handshake, and secondly the height of the lens that guides the light accurately onto the image sensor.

For the first issue, SMA actuators are more than one millimetre thinner than those using the incumbent voice coil motor (VCM) technology.

If SMA addresses the camera bump being caused by the first issue of the actuator, then the lens thickness may still cause a bump as the next weakest link in the chain. Currently smartphone camera lenses are made from plastic. In contrast, professional handheld camera lenses are made from glass, as it is a higher quality and more powerful material to guide light. Glass lenses are being developed by smartphone lens companies to provide improved performance and in parallel reduce the thickness of the lens.

A complication of using glass lenses is that they are much heavier than their plastic equivalent. The incumbent VCM actuators are lower force than CML’s SMA actuators and the additional weight of glass lenses compromises the performance of VCM actuators, to the point where there is an overall reduction in camera performance and functionality. CML have demonstrated that our SMA actuators can move glass lenses without any impact on actuator performance.

CML’s manufacturing partners have already shipped SMA actuators in mass production under licence from us for numerous devices, addressing other major industry issues such as mechanical impact resistance and power consumption. We are currently working on projects to deliver market-leading miniaturisation to remove the camera bump (for good) and look forward to sharing the details shortly when these products are available in the open market.

Adoption of OLED Displays in Smartphones

Monday, April 9th 2018

In recent years most smartphones have featured LCD displays, although flagship handsets are now adopting OLED panels as their choice display technology. TrendForce predicts that the penetration rate of OLED panel in smartphones will reach 46% by 2021.

OLED panels are self-emitting and therefore, unlike LCD displays, do not require a backlight. The lack of a backlight means that OLED panels can be made thinner than LCD displays, which allows smartphone vendors to be more flexible over the thickness of handsets. Another key factor currently contributing to the thickness of the handset is the camera, with many smartphones featuring a rear camera bump as a design compromise. SMA actuators are lower height than the VCM actuators currently used in smartphone cameras. CML believes that its SMA actuator technology would assist in facilitating the smartphone thickness reduction enabled by the adoption of OLED panels.

A further benefit of OLED panels over LCD displays is that OLED panels are bendable. This would allow smartphone vendors to develop handsets with folding displays which enable the user to switch between a compact phone sized screen and a wider screen closer to that of a tablet. The incorporation of foldable displays is likely to result in handsets consisting of two halves and would be a significant change in design form. CML believes that its low height SMA actuator designs would support smartphone vendors in ensuring that foldable handsets do not become considerably thicker than current smartphones by reducing the height of the camera.

MWC Sees Cameras Central to Smartphone Marketing and New Design Form Factors

Monday, March 5th 2018

More than 107,000 attendees walked through the doors at Fira Gran Via to join the Mobile World Congress (MWC) exhibition in Barcelona from 26 February to 1 March. Professionals from 205 countries and territories were present, and the event was covered by approximately 3,500 members of the international press and media. More than 2,400 companies showcased cutting-edge products and services across 120,000 square metres of exhibition and hospitality space.

Handset vendors continue to showcase camera specifications as a key tool to market their latest products. Almost all brands’ premium devices contained dual main cameras to enhance the photographic experience, and some mainstream models also benefitting from their addition. Samsung’s S9 and S9+ models were both launched at MWC 2018, the latter with dual OIS cameras. Samsung’s S9+ now joins Apple’s iPhone X as the only two handsets offering OIS functionality in both the wide angle and zoom camera, as the top two global brands seek to push the limits of imaging experience. The industry’s other major brands are expected to follow suit in the future.

Possibly, in answer to the question of what will be coming next - although Huawei announced no new smartphones at MWC, there were numerous advertisement hoardings and displays preparing the market for the launch of their P20 handset model in Paris on 27 March. Although still open to some interpretation, the implication of Huawei’s marketing is that the P20 will contain triple rear cameras, powered with Artificial Intelligence (AI) algorithms.

Other smartphone makers seeking to challenge convention were Nokia and ZTE with novel device form factors. Nokia stimulated the global media with the re-release of the 8110 ‘banana-phone’ with a slider to protect the keypad and move the microphone into position during calls. More boldly, ZTE release its Axon M handset with dual screens, to double the available display size to make messaging an easier task and improving the movie viewing experience. It remains to be seen whether this will set a trend in the other major players and see the launch of several new multi-screen devices in the future.

3D Sensing at CES

Tuesday, January 16th 2018

This year’s annual CES show was held in Las Vegas between 9th and 12th of January.  The CES show is used to showcase upcoming products and to gauge interest in concept products by most of the world’s largest technology companies.

From CML’s point of view, the most interesting feature from the show was in the world of virtual and augmented reality.  Several companies announced new models of virtual reality headsets with many including cameras on the outside of the headset.  Currently, virtual reality headsets feature internal cameras as they are required to track eye position in order to deliver an immersive 3D experience to the user.

The addition of external cameras to headsets enables augmented reality functionality.  Augmented reality is a special effect that superimposes digital images over real ones and enables users to extend the virtual reality experience to their real world environment.  CML believes that the growing popularity of augmented reality will result in increased adoption of the technology in smartphones and will create a demand for more sophisticated content.

Although augmented reality content already exists in smartphones, its applications remain relatively narrow and primitive.  The demand for more sophisticated content will require significant enhancements in the quality of 3D sensing modules and in particular the quality of the depth map used to generate the 3D model.

At present, 3D sensing is being used in the front facing camera in the form of facial recognition.  However, users have expressed concerns over the current level of accuracy and failure rate. CML is developing new solutions which will enhance the accuracy of 3D sensing modules, therefore reducing the failure rate and delivering the improvement in the security of facial recognition applications that the market demands.

CML also believes that the demand for more advanced and varied augmented reality content will result in its inclusion into the main rear facing camera of smartphones. Rear facing 3D sensing requires a higher range and accuracy than its front facing counterpart.  This is because rear facing 3D sensing needs to deal with a far greater variety of target scenes. CML is working on a variant of its front facing 3D sensing solution to deliver the considerable enhancements required to facilitate rear facing 3D sensing and deliver a high quality, reliable augmented reality experience.

SMA Actuators Capable of Driving Glass Lenses

Friday, November 3rd 2017

The drive to improve image quality in smartphone cameras has seen vendors invest in next generation glass lenses, e.g. the LG V30 is shipping with hybrid lenses. Glass offers an inherent advantage over plastic when used to make lenses as it has lower dispersion, higher refractive index and better scratch resistance. Dispersion is a mechanism that produces disruptive colour fringes, and a lower dispersion material will produce a lens that is optically purer and gives a clearer image. The higher refractive index of glass means that lenses can be made thinner than an equivalent plastic lens, leading to a thinner camera design.

A feature of glass is that it is significantly denser than plastic, and even though lenses can be made thinner, they have a higher mass than a plastic lens. The additional weight of these lenses compromises the performance of auto-focus and optical image stabilisation mechanism based on voice coil motors as the means to drive actuation.

In a recent news release CML stated that the use of heavier glass lenses should be well within the performance envelope of SMA based actuators and we are pleased to report that our expectations for high level operation have been confirmed.

We have taken SMA OIS actuators and characterised the image shake suppression performance, using our state of the art automated measurement equipment. The measurement was repeated for a range of lens masses including standard plastic lenses, current state of the art of hybrid glass lenses and significantly greater masses than are expected for next generation glass designs. We have demonstrated that image shake suppression levels were independent of the mass of the lens assembly and that CMLs SMA technology can overcome the limitations that VCM actuators have when driving heavier lenses.

Innovation Trends in the Smartphone Camera Market

Friday, October 20th 2017

The recent launch of new flagship smartphones confirmed that the camera remains the key means of differentiation between brands.  All brands have innovated and there have been some common approaches to improving the camera functionality:

Wider Use of Dual Cameras

Dual cameras feature on nearly every flagship smartphone.  Aside from the well-known Bokeh effect dual cameras provide better zoom, dynamic range and low-light performance than single aperture devices.

More Sensitive Image Sensors

The improvement in image sensors has shifted from increasing pixel count to making them more sensitive or providing them in pairs.  Greater sensitivity improves low-light performance, whereas dual pixels provide improvements to dynamic range.

Faster Image Processing

Enhanced image processing capabilities are being used to combine several images to give better results or to recognise what is being photographed and set the camera accordingly.

Use of Glass and Hybrid Glass Lenses

As sensors improve the quality and size of lens elements is also improving.  However, such lenses are heavier, and manipulating these lenses needs higher forces than currently employed.

Wider deployment of Optical Image Stabilisation (OIS)

Concomitant with the innovations above, OIS has been introduced more widely to take advantage of low-light performance or to facilitate the capture of multiple images.  The first dual cameras with OIS have been introduced as well as OIS on a front facing camera.

 CML believes that innovation in the smartphone camera market will continue.  CML expects the number of cameras per smartphone to continue to increase and that OIS will feature on every lens.  As smartphone form factors converge towards sleek feature free devices, the ability to deliver lens actuation in a compact low-profile design will become increasingly important.  The move to heavier lenses is a challenge for most actuators, but is within the performance envelope of SMA.

The Future of the Smartphone Camera Market

Wednesday, September 13th 2017

Yesterday’s event to launch the iPhone X marked the end of the recent season of flagship smartphone launches by the industry's two largest smartphone vendors. The new devices give some insight into the future of the smartphone camera market.

Apple and Samsung have both introduced handsets with dual cameras with the OIS function on both apertures in an effort to widen the range of photographic techniques that can be used. It remains the case that the quality of the camera is used as a key means of product differentiation in the premium smartphone sector.

The introduction of face recognition by Apple also confirms a further trend: the number of optical devices per smartphone is increasing. Face recognition relies on 3D mapping technology, which requires the use of six optical devices. It is expected that other vendors will follow suit, and add devices to improve face recognition and augmented reality.

CML believes that innovation in the smartphone camera market will continue to fuel strong demand for new products. CML also believes that the increase in the number of OIS controlled cameras and other optical devices per smartphone means that the growth rate in the miniature camera market will outpace the growth in the smartphone market. This strong market demand is good news for CMLs core business.

More Evidence of Growth in Camera Market

Thursday, August 3rd 2017

This week both Apple and Sony released information to the market relating to their performance in the last three months. 

Apple revealed that they had sold 41 million iPhones in the last quarter.  Through a code release Apple also inadvertently revealed that the next iPhone will include facial recognition using an additional front facing infrared camera.

Sony’s consolidated financial results reported its highest-ever first-quarter operating profit.  The profit surge has been driven by sales of Sony’s market leading image sensors, used in smartphone cameras.  Sony are set to open additional production facilities that will increase image sensor manufacturing capacity by around 20%, reflecting confidence that the smartphone camera market will continue to grow.

CML thinks these announcements provide further evidence that the high demand for cameras in smartphones remains unabated.  The leak that the next iPhone will include a second front camera – taking the number of cameras up to four per smartphone - is in line with most analyst’s view that the volumes for camera modules is set to continue to increase.

It is also noteworthy that camera module ASPs are increasing.  In contrast to the view that margins in the smartphone market have been squeezed, particularly in China, the margins attached to smartphone cameras and the high quality optical components that differentiate one smartphone from another remain healthy.

After establishing itself as a provider of precision SMA actuator platform technology and delivering products in the smartphone and drone camera markets, CML is now launching a new design for a next generation haptic experience. Conventional products provide the user with a feedback sensation by shaking the entire device (smartphone or wearable), resulting in an unnatural effect. CML's solution creates a more sophisticated and nuanced experience by providing a localised feeling. SMA can create strong forces in a limited space without the use of magnetic parts, thus preventing compromise to antennae, audio speakers or NFC components' performance.

During the talk, CML will explain SMA actuator characteristics, its advantages when applied to haptics and how we are taking this technology to the mass market.

Drones: flying high in the consumer market

Tuesday, February 14th 2017

The value of the drone market is rising fast. According to Goldman Sachs, it will be cumulatively worth $100 billion by 2020.

There are many potential applications for drones. Investment in them by the military and security forces is rising, while in the commercial market, usage of drones in construction, surveying, and oil pipe inspection, for example, is growing too.

Next-generation consumer drones
Photography and videography are thought to be the key applications for next-generation drones. Mainstream consumer usage is the dream, but safety concerns may prevent very early adoption. However, drones seem to be here to stay, and in increasing numbers.

To expand usage, with flight times of up to half an hour and travelling at speeds of at least 30mph to 40 mph, they will need to be safe and robust, as well as capable of being accurate in navigation to avoid buildings, trees, pylons and other flying objects. They will also need to be small and lightweight with high-precision performance.

Offering exactly these features, CML’s unique smart material technology will shortly ship in high-end consumer drones available to the global market. “We see drones as one of the most exciting new major emerging product trends," commented CML's marketing director Dominic Webber. "We’re delighted to be integral to the development of key components in this high profile segment.”

Innovation And An Invitation: Improving Health and Quality of Life for Diabetics

Thursday, February 2nd 2017

CML will be at the 10th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD), 15 to 18 February.

Worldwide, an estimated 415 million people are suffering from diabetes, a life-long condition that can result in serious complications such as heart disease, stroke, and kidney damage. That total is projected to rise to 642 million by 2040, meaning that one in 10 adults would be diabetic.

Trillion dollar industry
Such a prevalence of disease demands a lot of money spent on treating it. The estimated global healthcare expenditure on diabetes treatment in 2015 came to $935 billion.

Most diabetics need regular injections of insulin. Yet current insulin delivery devices do not offer a satisfactory balance of size, weight, cost and dosing accuracy. Users claim their pumps, pens or syringes are indiscreet, too bulky or uncomfortable to live with.

Equally, most devices that offer both convenience and advanced functionality are prohibitively costly for healthcare providers and insurance policies, both in developed and developing nations.

Revolutionary insulin delivery
To help overcome these blocks – and positively impact the lives of diabetics everywhere – CML is now developing revolutionary next-generation insulin delivery devices. Our unique smart material platform technology allows us to create miniaturised lightweight products for this market at a low cost.

What’s more, our products offer as much precision in insulin delivery – a requirement recognised as critical to managing diabetes – compared even to the most sophisticated of products currently available.

We will be discussing our transformative plans and developments with pharmaceuticals manufacturers and device makers at ATTD 2017 in Paris. If you’d like to arrange a meeting with us there, please contact us to agree a convenient time.

Trend Prediction: Dual and Selfie OIS Cameras

Tuesday, January 24th 2017

TechSpot blogger Tim Schiesser recently posted a very detailed description of his dream smartphone for 2017. He covers all the key features, including display, body, processor, cameras, battery and software.

What really caught our eye was Tim's wish for OIS functionality in both the main dual cameras and the selfie camera. Why? To improve low-light performance, traditionally the weak point of smartphone cameras.

Were Tim’s wish granted widely in premium handsets, it would represent a potential tripling of the overall market size in this segment, to over a billion units per annum – great news for OIS actuator suppliers.

To quote Tim’s wishlist:

  • Both rear cameras will feature optical image stabilization to improve low light performance. Both will also be capable of shooting 4K video at 30 FPS, alongside 1080p at 120 FPS and 720p at 240 FPS, with high quality stereo audio.
  • The wide angle camera will use an f/1.9 lens, while the zoom camera will use an f/2.2 lens as increasing the aperture of this 72mm lens any further would have led to a larger-than-reasonable camera module.
  • The front camera will be another Sony IMX260, this time paired with an f/1.7 24mm lens and OIS.
  • The ideal smartphone won’t be the first handset with OIS for its front facing camera (the HTC 10 included this feature), but it’s a smart inclusion that helps deliver the best low light selfies. Again, this sensor would pack 4K video recording.

We understand smartphone makers have already recognised the benefits and demand for dual OIS cameras but hit development issues with conventional products due to magnetic interference between the cameras and also with other critical components – such as loudspeakers and antennae – that compromised picture quality, audio and signal strength.

This is partly why CML SMA OIS products aren’t made with magnets, and simply don’t suffer these issues. Ever.

Camera technology pioneers hTC and Sony are the only smartphone makers so far to have launched selfie OIS cameras. As most major brands continue to increase camera resolutions and specifications, we predict that the selfie OIS will be a significant consumer trend soon.
