Structure of the single solid-state image sensor is similar to retina of human being. Red, green and blue color filtered photo detective cells are densely allocated. In recent years, along with increase of its numbers, pixel size tends to decrease. This trend make the image much noisy. On the other hand, in digital cinema, it is required that 20 million pixels spatial resolution and 60 flame/sec time frequency. In the case of the camera using digital cinema, acquired image unavoidably include large amount of noise. To acquiring the true image mingled with noise, it is necessary to integrate the highly-developed image processing mechanism fulfilled in the human vision system. In this research, on the assumption of the image sensor which structure resemble retina, we exploit the highly-developed image processing technique for acquired image. Further more, on the assumption of the highly-developed image processing technique, we study desirable structure of the image sensor.

单固态图像传感器的结构类似于人的视网膜。红、绿色和蓝色滤光光检测单元被密集地分配。近年来，沿着其数量的增加，像素尺寸趋于减小。这种趋势使图像变得非常嘈杂。另一方面，在数字电影中，要求2000万像素的空间分辨率和60帧/秒的时间频率。在使用数字电影的相机的情况下，所获取的图像必然包括大量的噪声。为了获得混有噪声的真实图像，需要结合人类视觉系统中高度发达的图像处理机制。在本研究中，我们假设影像感测器的结构类似于视网膜，并利用先进的影像处理技术来处理所撷取的影像。在此基础上，在图像处理技术高度发展的假设下，研究了图像传感器的理想结构。
