Abstract
A moving image encoding apparatus that encodes a moving image and generates encoded data includes an extraction unit configured to extract a brightness change direction for each of blocks acquired by dividing the moving image; and a pixel value control unit configured to control pixel values of a locally decoded image based on the brightness change direction extracted by the extraction unit, for each of the blocks acquired by dividing the moving image.
