摘要：
A moving image compression-coding device has a pixel determination module configured to determine whether a color of each pixel in a macro block having a plurality of pixels in an input image is a predetermined color, a pixel counter configured to count a number of the pixels having the predetermined color in the macro block, a macro block determination module configured to determine whether a color of the macro block is considered to be the predetermined color according to the count result, and a compression-coded data generator configured to compression-code the input image with a compression ratio depending on the determination result.
