Abstract
A moving image coding device includes: a evaluation unit configured to approximate a parameter of a statistic in accordance with a distance from a reference pixel located along the intra prediction direction to a pixel to be processed; a feature amount calculation unit configured to calculate, for a pixel near the pixel to be processed, a feature amount of a prediction value that is based on the intra prediction direction; and a prediction value calculation unit configured to estimate a prediction error corresponding to the distance using the parameter of the statistic approximated by the evaluation unit, reflect the prediction error in the prediction value that is based on the intra prediction direction using the feature amount calculated by the prediction value feature amount calculation unit, and generate a new prediction value.
