Abstract
An apparatus for coding video in one of a plurality of prediction modes executes a first process for calculating first evaluation values regarding each of the plurality of prediction modes, based on a plurality of luminance prediction errors, each luminance prediction error being a difference between luminance of each pixel in an input image and luminance of each pixel in a prediction image, a plurality of color difference prediction errors, each color difference prediction error being a difference between a color difference of each pixel in the input image and a color difference of each pixel in the prediction image, and a calculation result of the luminance prediction errors and the color difference prediction errors; executes a second process for selecting a predetermined number of prediction modes from the prediction modes, based on the first evaluation values.
