Abstract
An image processing device includes an image encoder, a memory and an image decoder. The image encoder receives an input image frame, retrieves luminance information and chrominance information from the input image frame, respectively, encodes the luminance information to generate an encoded luminance frame, and encodes the chrominance information to generate an encoded chrominance frame. The memory includes a first memory portion, a second memory portion and a third memory portion. The first memory portion stores the encoded luminance frame, and the second memory portion or the third memory portion stores the encoded chrominance frame. The image decoder reads the encoded luminance frame from the first memory portion to perform decoding, and reads the encoded chrominance frame from the second memory portion or the third memory portion for decoding.
