Information processing apparatus, information processing method, and information processing program

Abstract

An apparatus includes a memory and one or more processors. The processors code each block in a frame of moving images with use of a reference image. The processors generate a decoded image by decoding a coded block and calculate evaluation values for selection of each type of offset filtering. The processors also determine whether the block to be coded is a static region and make an adjustment in the evaluation value on the first offset filtering, based on a layer position of the reference image in a time direction upon a determination that the block to be coded is the static region. The processors also select the type of offset filtering based on the evaluation value on first offset filtering having undergone the adjustment and the evaluation values on second offset filtering and third offset filtering and carry out the selected offset filtering for the decoded image.
