The pros and cons of camera performance have become an important reference indicator for today's consumers to purchase smart phones. Therefore, more and more manufacturers pay attention to improve the camera's camera performance! It can be said that in the past two years, the mobile phone camera effect has become a part of the terminal equipment directly. 'Core competitiveness' or one of the 'selling points', such as the Samsung Galaxy S8 series, S9 series mobile phones, outstanding color performance loved by users, and the leading dark light, low light and night scene imaging effects are amazing , and even become the direct cause of the user's 'grass'.
At the Shanghai World Mobile Conference held from June 27th to 29th, Samsung's System LSI booth demonstrated many cutting-edge technologies that help Samsung's mobile phones become photo leaders, not only familiar super slow motion, etc. And so on, including Samsung's new ISOCELL Plus technology.
It is reported that on June 27, Samsung Electronics Co., Ltd. introduced a new ISOCELL Plus technology. The application of this technology enhances the ability of CMOS image sensors to capture light, greatly improving the photosensitivity and color reproduction. Smartphone users can be extremely challenging Under the low light environment, shoot more accurate and clear photos.
In order to take high-quality photos, CMOS image sensors need to capture as much light as possible and accurately transmit color information to photodiodes. In 2013, Samsung solved the related requirements by introducing ISOCELL technology. A physical barrier is formed between pixels, reducing color crosstalk and increasing full-well capacity. Compared to traditional back-illuminated (BSI) image sensor designs, ISOCELL technology allows each pixel to absorb and store more light. For better image quality.
With the introduction of ISOCELL Plus technology, Samsung is pushing pixel isolation technology to a new level with further optimized pixel structures. In existing pixel structures, metal plates are usually formed on photodiodes to reduce the number of pixels Disturbance, but because the metal tends to reflect or absorb incident light, it also causes light loss. With ISOCELL Plus, Samsung replaced the metal plate with innovative materials developed by Fujifilm to maximize Reduced light loss and light reflection.
'We value the strategic partnership with Samsung and congratulate the completion of the ISOCELL Plus R&D,' said Naoto Yanagihara, Head of the Fujifilm Research and Development Department. 'This development is an important milestone for us and it marks our new material. The first commercialization. Through continuous cooperation with Samsung, we look forward to more meaningful innovation in the field of mobile cameras.
The new ISOCELL Plus technology has a higher color reproduction and a 15% increase in sensitivity. The technology also enables the image sensor to be equipped with 0.8 micron (μm) or even smaller pixels without losing any performance, making it The best solution with a resolution higher than 20 megapixel camera.
'In cooperation with Fujitsu, a leading company in the information technology industry, we have further advanced the upgrade of CMOS image sensor technology.' said Ben K. Hur, vice president of marketing for System LSI, Samsung Electronics. 'ISOCELL Plus is not only capable of super development.' Small pixel size and ultra-high resolution sensor, also improves sensor performance. '
