1. An image processing device comprising:
a multimedia processor configured to process image data of a pixel of an image frame, wherein the image data comprises first image data and second image data, the first image data comprising a plurality of bits for the pixel including a most significant bit (MSB) of the image data and the second image data comprising a plurality of bits for the pixel including a least significant bit (LSB) of the image data; and
a frame buffer compressor configured to perform compression on the image data of the pixel using a first compression and a second compression, wherein performing the compression on the image data comprises:
performing a prediction operation on the image data of the pixel to form first residual data corresponding to the first image data and second residual data corresponding to the second image data;
performing the first compression on the plurality of bits of the first image data of the pixel including the MSB of the image data based on the first residual data, and
performing the second compression on the plurality of bits of the second image data of the pixel including the LSB of the image data based on the second residual data, wherein a compression type of the first compression is different from a compression type of the second compression.
