The emergence of three-dimensional image fingerprint sensor CMOS explosive

Recently, researchers at UC Davis and the University of California, Berkeley, developed an ultrasonic fingerprint sensor based on MEMS and CMOS technology to obtain three-dimensional images of fingerprints, which will greatly enhance the security of fingerprinting. Fingerprint sensors are more and more widely used in smart phones and other equipment. The use of fingerprints to unlock and pay for features such as security than the traditional password has been greatly improved. Previous fingerprint recognition was a two-dimensional image extracted by a sensor that could bypass fingerprinting by printing a fingerprint pattern. Three-dimensional image extraction will undoubtedly further improve the accuracy and security of fingerprint recognition. CMOS image sensor in the field of smart phones dominate Since Apple released iPhone5s fingerprint recognition technology began to be concerned about when the technology gives the feeling is very high, then some Android phones also use a fingerprint sensor, but also are basically in the high-end models Will appear. After two years, fingerprint recognition technology began to explosive growth in the smartphone, the new conference, whether it is high-end machine or entry-level machine, you can see everywhere fingerprint manufacturers as the biggest selling point of mobile phones thing. For a time, fingerprint recognition has gradually become a standard feature of smart phones. CMOS image sensor, which is an important part of fingerprint recognition technology, has changed greatly in 2015. Yole Developpement (Yole) report "2015 CMOS image sensor industry trends (Statusofthe CMO Simage sensorin dustry2015)" shows that the CIS market in 2015 will reach 10 billion US dollars. In addition, Sony's productivity investment in support of its technological superiority and outstanding performance of its Apple product strategy has been fruitful, gaining more than a third market share and leading the entire smartphone industry. Sony's competitors are not optimistic. South Korea's Samsung Electronics for quality considerations, had to buy Sony sensors, for the flagship smartphone models. In addition, Omni Vision Technologies (and foundry TSMC) are latecomers involved in advanced technologies such as Back Side Illumination (BSI) and Phase Detect Auto Focus (PDAF) , Has been struggling to grab the share of low-cost sensors. From the future development, CMOS image sensor industry competition will be more reflected in the industry consolidation, resource integration, market control ability of the overall strength, CMOS image sensor will be toward a better camera experience, faster focus speed, More intelligent application development experience. In the mobile phone, automotive, security applications in different fields In the mobile phone market with the largest amount of CMOS image sensors, photos are still mainly used for shooting still images, and the requirements for high resolution are getting stronger and stronger. Basically, more than 8 million pixels meet or exceed the quality of the same digital camera . On the other hand, in addition to taking still photos, video clips are being captured and uploaded to the Internet in more and more applications. For example, FullHD Full HD videos can now be taken. In the future, 4K2K super high resolution and high-speed slow motion photography Playback and other applications has become the trend of the times, and accordingly, these applications make the CMOS image sensor in achieving high resolution, but also require high-speed response capability. In the car camera, it is said that by 2016, the size of the market is expected to reach 80 million / year or more. Currently the main demand in this area is VGA resolution products, the current mainstream of the application system is the analog interface, but also some companies in the development of digital interface with the system products, such as HD (720p, 1.3 million pixels) , Full-HD Full HD (1080p, 2MP), etc. All products need high sensitivity and wide dynamic range performance. In the field of monitoring, compared to the past Sony CCD sensor dominated the world pattern, the development and promotion of CMOS sensors can really carry the banner of security monitoring industry? In this regard, the industry expressed cautious optimism. Conclusion: Yole's latest report, "CMOS Image Sensor Industry Trends 2015," predicts that by the handset and automotive markets, the CIS market will have an average annual growth rate of 10.6% from 2014 to 2020. By 2020, the market size will be Reaching 16.2 billion U.S. dollars. CMOS image sensors have huge space for applications in mobile phones, automobiles and security. With the demand of related technologies and smart times, the market for CMOS image sensors is worth looking forward to, and the manufacturers of CMOS image sensor industry are at a great battle.
