Abstract:
An image processing apparatus, comprising:a memory, arranged to store image data, wherein the image data comprises luminance data and color data; a read-out unit, arranged to divide the image data stored in said memory into a plurality of large blocks, divide each of the plurality of large blocks into a plurality of reference blocks, and read out the stored image data on a unit basis of a reference block, each reference block being formed with m blocks of the luminance data and n blocks of the color data spatially corresponding to the m blocks of the luminance data, wherein said read-out unit reads out one reference block from each of N large blocks such that read-out positions of N reference blocks are not correlated with each other in a horizontal direction and/or a vertical direction; and an encoder, arranged to encode sequentially the image data of the reference blocks read out by said read-out unit, said encoder adjusting a code amount on an N reference block basis, wherein m and n are natural numbers, and N is a positive integer greater than two.
