Abstract
An image processing device includes a multimedia intellectual property (IP) block which processes image data including a first component and a second component; a memory; and a frame buffer compressor (FBC) which compresses the image data to generate compressed data and stores the compressed data in the memory. The frame buffer compressor includes a logic circuit which controls a compression sequence of the first component and the second component of the image data.
Claims20
An image processing device comprising:
- a multimedia intellectual property (IP) block configured to process image data including a first component comprising a luma component and a second component comprising a chroma component;
- a memory;
- and
- a frame buffer compressor (FBC) configured to compress the image data to generate compressed data and store the compressed data in the memory, wherein the frame buffer compressor includes an encoder and a decoder,
- wherein the encoder includes a first mode selector configured to determine whether to perform a first mode or a second mode,
- wherein the encoder includes a compress manager configured to control a compression sequence of the first component and the second component of the image data,
- wherein the compression sequence includes performing an entropy encoding, and the compress manager determines at least one parameter of the entropy encoding so that the chroma component is compressed to a number of bits smaller than a chroma target bit count determined from a target compression ratio and the chroma component.
