Title: MOVING IMAGE ENCODING APPARATUS, MOVING IMAGE DECODING APPARATUS, MOVING IMAGE ENCODING METHOD, MOVING IMAGE DECODING METHOD, AND PROGRAM
Abstract:
Provided is a moving image encoding apparatus for encoding a moving image, thereby generating encoded data. The moving image encoding apparatus comprises: an extraction means that extracts a brightness change direction for each of blocks obtained by dividing the moving image; and a pixel value control means that controls, on the basis of a brightness change direction extracted by the extraction means, the pixel values of a local decoded image for each of the blocks obtained by dividing the moving image. Provided is a moving image decoding apparatus for decoding encoded data obtained by encoding a moving image. The moving image decoding apparatus comprises: a decoding means that decodes the encoded data, thereby acquiring a brightness change direction extracted for each of blocks obtained by dividing the moving image; and a pixel value control means that controls, on the basis of the brightness change direction acquired by the decoding means, the pixel values of a local decoded image for each of the blocks obtained by dividing the moving image.
