Digital image processor for a digital camera
First Claim
1. A digital image processor for use in a digital camera having an image capture unit arranged lo output analog signals that represent the captured image, a converter unit for converting analog representations of the captured image to digital representations of the image, a memory for storing digital representations of the image, and a processing unit capable of directing components included in the digital camera, the digital image processor comprising:
- an input data stream processor for pre-processing images received from the converter unit and storing the pre-processed images in the memory; and
an output data stream processor arranged to receive pre-processed images and post-process the retrieved images into a viewable form.

Abstract
A digital image process for a digital camera contains a preprocessor and a postprocessor. The preprocessor can include, for example, a uniformity corrector, a sampling filter, a modulation transformer, and a ditherer. The postprocessor can include a color interpolator, an RGB reconstruction block, a digital compressor, and a color pattern data buffer. The digital image process is programmable to operate one or more of the processing blocks of one or both the preprocessor and the postprocessor for flexible programming that can adapt to the requirements of various digital camera designs or users.
