日本三菱电机公司已成功地在Si衬底上制作以前在GaAs衬底制作的人工网膜芯片。人工网膜芯片，能像人的眼睛那样同时进行图像的检出和处理的LSI，该公司独自开发作为代替CCD新的图像识别器件。在使用以前CCD的图像处理系统中，由于在获得大量图像后，依次进行运算处理，实时处理 Japan’s Mitsubishi Electric Corporation has successfully fabricated on the Si substrate in the GaAs substrate made of artificial omentum chip. The artificial omentum chip, an LSI that can detect and process an image like a human eye, was developed by the company as a new image recognition device instead of a CCD. In the image processing system using the conventional CCD, since a large number of images are obtained, the arithmetic processing is sequentially performed, and the real-time processing
