Circuit and method for adaptive, lossless compression of successive digital data

A method for processing a stream of correlated digital data with each digital data comprises a number of digital bits, comprising:

• dividing the stream of digital data into a plurality of data sections with each data section comprising at least one digital data;
• sequentially loading the digital data in one data section;
• and
• compressing the loaded digital data using a mapping table such that the mapping table stores only unique data states of the loaded digital data, and each entry in the mapping table corresponds to an index.

An image display system, comprising:

• a light valve comprising an array of individually addressable pixels;
• and
• an image processing unit for preparing a set of image data for the pixels of the light valve, comprising:
• a codec for compressing and decompressing a stream of image data of an array of image pixels of an image frame from an image source, further comprising:
• receiving means for receiving the image data stream;
• and
• compression means for compressing the received image data such that the image data of each image pixel are compressed at one time.
