Research of Human Processor-Type Image Acquisition System for Super High Quality Digital Cinema

单个固态图像传感器的结构类似于人类的视网膜。红色、绿色和蓝色滤色的照片侦测单元被密集地分配。近年来，随着像素数的增加，像素点的大小有减小的趋势。这种趋势使图像变得非常嘈杂。另一方面，在数字电影中，要求有2000万像素的空间分辨率和60个火焰/秒的时间频率。在使用数字电影的相机的情况下，获取的图像不可避免地包含大量噪声。为了获得混杂着噪声的真实图像，需要集成人类视觉系统中高度发达的图像处理机制。在本研究中，基于结构类似视网膜的图像传感器的假设，我们利用高度发达的图像处理技术对采集到的图像进行处理。此外，在图像处理技术高度发达的假设下，我们研究了图像传感器的理想结构。

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.
