Abstract
A method and an apparatus for processing an image are provided. A buffer is provided and separated into a series of storage units. Each storage unit has a fixed size. The image is divided into pixel groups, and each pixel group corresponds to one storage unit. Each pixel group is compressed by one of candidate compression methods to obtain compressed data so that the compressed data of each pixel group fits the corresponding storage unit.
Claims18
A method for processing an image from an image processor, comprising:
- providing a buffer separated into a series of storage units, each storage unit having a fixed size;
- dividing the image into a plurality of pixel groups by a processor, each pixel group corresponding to one of the storage units;
- compressing each pixel group by one of candidate compression methods to obtain first compressed data so that the first compressed data of each pixel group fitting the corresponding storage unit;
- and
- updating a portion of the image by a processor by:
- receiving updated image data by a processor corresponding to the portion of the image;
- dividing the updated image data by a processor into updated pixel groups;
- identifying the storage units by a processor corresponding to the updated pixel groups;
- and
- compressing each updated pixel group to obtain second compressed data by one of the candidate compression methods so that the second compressed data fits in the corresponding storage unit.

A display apparatus, comprising:
- a mapping device dividing the image into a plurality of pixel groups, each pixel group corresponding to one of storage units with a fixed size in a buffer;
- a compressor device for compressing each pixel group by one of candidate compression methods to obtain first compressed data so that the first compressed data of each pixel group fitting the corresponding storage unit;
- and
- updating a portion of the image by:
- receiving updated image data corresponding to the portion of the image;
- dividing the updated image data into updated pixel groups;
- identifying the storage units corresponding to the updated pixel groups;
- and
- compressing each updated pixel group to obtain second compressed data by one of the candidate compression methods so that the second compressed data fits in the corresponding storage unit.
