Abstract
An image processing device includes a buffer for receiving encoded image data, and a processor to execute instructions that cause the processor to: decode the encoded image data from the buffer to generate quantized transform coefficient data; inversely quantize the quantized transform coefficient data using a 32×32 quantization matrix to generate predicted error data, the 32×32 quantization matrix includes a duplicate of at least one of two elements adjacent to each other from an 8×8 quantization matrix; and combine the predicted error data with a predicted image to generate decoded image data.
