Samsung has just announced their ISOCELL CMOS image sensor technology which they say beats back side illumination (BSI) sensors in other cameraphones. According to Samsung, BSI has limitations in that the cross-talk interference is higher the closer pixels are to each other, which happens with larger megapixel camera sensors. Through Samsung's ISOCELL, each pixel is isolated, allowing it to catch more light from the sensor resulting in better exposed, blur-free photos shot in low-light conditions.
According to Samsung, ISOCELL camera modules will have 30% better colour accuracy and the same 30% better dynamic range capture. In addition, ISOCELL modules are also slimmer due to 20 percent wider chief ray angle, allowing them to fit into slimmer devices. The first Samsung ISOCELL sensor codenamed the S5K4H5YB has already been detailed and is an 8MP 1/4" module with 1.12 micron ISOCELL pixels. It is currently making the sampling rounds amongst customers and is set for mass production in Q4 of 2013, which could see the next generation of Samsung smartphones sporting ISOCELL camera sensors. Samsung had this to say:
"Through advances in pixel and process technology, smartphone and tablet cameras have made it easier than ever for consumers to capture and share beautiful, clear images with the world. ISOCELL technology is yet another innovation that significantly raises the bar in image quality, and demonstrates Samsung's technology leadership in image sensors for mobile devices."
