CODING APPARATUS, CODING METHOD, AND STORAGE MEDIUM

摘要

In order to prevent such inconvenience that the effect of improving the image quality by allocating a large amount of code to an intra picture is lost in intra blocks included in an inter picture so that the image quality of the inter picture is deteriorated, a coding apparatus for coding an image on a block-by-block basis includes an acquisition unit configured to acquire a coding complexity of an intra picture and a coding complexity of an inter picture, the intra picture and the inter picture having been coded previous to the image, and a determination unit configured to determine a quantization parameter, which is used to code each block targeted for coding in the image, based on a picture type and a block type of the image and the coding complexities of the intra picture and the inter picture acquired by the acquisition unit.
