Abstract
An input image is subjected to image region determination in a unit of prescribed block. Based on a result of image region determination, two or more pieces of layer data, of which validity or invalidity at the time of reproduction of the image is defined in a unit of prescribed block are generated by using data of the input image. Then, each of the two or more pieces of layer data is subjected to coding processing under a coding condition suitable for each of the generated two or more pieces of layer data, in a unit of block suitable for each of the two or more pieces of layer data.
