ABSTRACT:
An object of the invention is to provide an image coding device and an image decoding device enabling a transmitting color function through irreversible coding by performing the processing to reduce the occurrence of noises at the encoder's end without using a mask image. A grayscale shift unit shifts the grayscale of a transmitting color of an original image, after which a coding unit performs irreversible coding on the image. A transmitting color judging unit judges the transmitting color of a decoded image based on luminance information alone, and an up-sampling unit restores an outline of an object faithfully without being accompanied by deterioration in resolution resulted from the sub-sampling. It is thus possible to obtain a high-quality image with fewer noises.
