Abstract:
1. A digital camera, the digital camera comprising: an imaging unit including an image sensor and imaging optics; a digital image processor connected to receive raw digital images from the imaging unit and to process the raw digital images; a memory configured to store digital image data that has been pre-processed by the digital image processor; a microprocessor configured to direct retrieval of the digital image data that is stored in the memory; and a display for viewing digital images; wherein the digital image processor comprises a pre-processing portion and a post-processing portion, the pre-processing portion including a uniformity corrector configured to correct non-uniformities in the raw digital images using Photo Response Non-Uniformity (PRNU) correction and including a sampling filter, which receives corrected raw digital images from the uniformity corrector, and is configured to reduce the amount of data in the raw digital images for immediate viewing on the display before post-processing operations including color interpolation, RGB reconstruction, and compression.
