Abstract
Recently, smartphones are equipped with high resolution mobile camera modules of 100 million pixels or more. After that, it is expected that much higher resolution mobile camera modules will be mounted. However, in order to mount more pixels in a limited space, the pixel size must be reduced. If 1.0 um pixel sensor was the mainstream in the past, now 0.64um pixel sensor has been developed now, and a sensor with smaller pixel will be developed in the future. However, there are technical limitations. In terms of image quality of sensor, if the size of pixel becomes smaller, the amount of light received decreases, and the image quality in terms of noise becomes poor. In order to solve this limitation, an attempt is made to develop a high-sensitivity sensor in various ways. One of them is the image sensor using CMY color filter technology. CMY color filter has higher sensitivity than RGB, so it is advantageous for developing high sensitivity sensors. In this paper, we introduce a method to Image quality evaluate the CMOS image sensor equipped with CMY color filter in mobile devices.
