摘要： Provided is an image quality evaluation system for evaluating quality of an image. The image quality evaluation system includes bit extraction means and image quality evaluation means. For predetermined data expressing an image frame of a first image, the bit extraction means extracts a predetermined number of bits which is smaller than the number of bits required for expressing one data piece. By using a value expressed by the bit string extracted by the bit extraction means and a value of data equivalent to the data to be extracted from the bit string in a second image, the image quality evaluation means estimates a difference between the first image and the second image and evaluates the image quality of the first to image or the second image.
