Non-transitory computer-readable storage medium, encoding processing method, and encoding processing apparatus

A non-transitory computer-readable storage medium storing an encoding processing program that causes a computer to execute a process, the process including acquiring image feature information of each of a plurality of image regions obtained by partitioning first image data and image feature information of each of the plurality of image regions obtained by partitioning second image data, determining, for each of the plurality of image regions, whether image feature information of the first image data and image feature information of the second image data have a correlation greater than or equal to a certain value, and coding a specified image region of the second image data which has the correlation, the coding being performed by using coding unit used for coding of an image region of the first image data whose position corresponds to the specified image region of the second image data.
