Abstract:
An image decoding apparatus for decoding coded image data which includes coded texture data obtained by coding texture data expressing the luminance or chrominance of an image, and coded shape data obtained by coding shape data expressing the shape of the image, thereby generating decoded image data including decoded texture data and decoded shape data, said apparatus comprising:arithmetic decoding means for subjecting the coded shape data to arithmetic decoding to output the decoded shape data; padding means for padding the pixel values of pixels positioned outside a target image to be decoded, in an image space including the target image, which image space is constituted by the decoded texture data; composition means for compositing the decoded texture data of the target image and texture data of another image; at least one of the arithmetic decoding means, the padding means, and the composition means being constituted by a hardware circuit; and a processor for controlling the hardware circuit.
