Abstract
To aim to achieve addition of blur to an image based on distance information of a subject and to appropriate determination of a block size that is a unit for coding. Blur is added to the image with use of one of disparity information for each pixel unit and distance information for each pixel unit and arbitrary blur conditions. A block size of each region of the image that are to be divided into blocks for coding is determined based on a blur value of the region. The image is divided into blocks based on the determined block sizes and coded in units of blocks. By increasing a block size with respect to a region included in an image having a high blur value, it is possible to reduce processing amount of reference block searching, thereby achieving speed-up of processing and reduction in processing amount.
