Image coding equipment and image coding program |
摘要 |
Image coding equipment wherein no sense of incongruity occurs when domains whose image quality should be improved are selected. To the domains selected with the domain selection section 111, the gradual coding parameter calculation section 112 computes the quantization values so that the quality of image may improve gradually toward the central part from the outside of the selected domain, and a picture is coded based on the value of such a parameter. <IMAGE> |
