Title:
DIGITAL IMAGE PROCESSOR
Document Type and Number:
WIPO Patent Application WO2003065732
Kind Code:
A3
Abstract:
An electronic chip for processing a digital image stream having digital data values representing pixels and resulting digital signal. The electronic chip includes a compression module for compressing the digital image stream so that upon decompression the digital image stream maintains a pre-determined signal to noise ratio for each digital data value. The compression module may compress the digital image stream such that digital data values are quantized so as to maintain a desired resolution over all frequencies. The electronic chip may further include a digital image input port for receiving the digital image stream and a digital data output port for outputting the digital data stream formatted as a digital data packet.
