摘要

A video image decoding device executes a separation process for extracting, from encoded video image data including multiple images, first encoded data obtained by encoding reduced images of first images included in the multiple images, and second encoded data obtained by encoding second images included in the multiple images, executes a first decoding process for decoding the reduced images of the first images from the first encoded data, executes a second decoding process for decoding the second images from the second encoded data, executes a recording process that includes recording first region included in the reduced images, the first region including motions with respect to the second images immediately preceding the first images, and executes a synthesis process for reproducing the multiple images by modifying second region in the second images immediately preceding the first images in accordance with the first region.
