Abstract:
1. In a digital imaging system, a method for distributed digital image processing, the method comprising: receiving compressed luminosity information at a device, the compressed luminosity information generated by a second device in a first set of data packets corresponding to a color image at a first level of photographic significance, wherein the compressed luminosity information is packaged with header information identifying individual bit planes that comprise the compressed luminosity information, and wherein the compressed luminosity information generated by the second device is packaged into a plurality of data packets suitable for progressive transmission of image data corresponding to varying levels of photographic significance; restoring the luminosity information from the first set of data packets of compressed luminosity information; converting the compressed luminosity information, corresponding to the transmitted data packets, into the color image at the first level of photographic significance; receiving a second set of data packets generated by the second device corresponding to a higher level of photographic significance of the color image; and converting the color image to a higher-quality representation by synchronizing the first set of data packets and the second set of data packets to obtain the color image at the higher level of photographic significance.
