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.

19. A digital image processor for use in a digital camera having an imaging device arranged to output digital images and a memory for storing digital images, the digital image processor comprising:
-
a preprocessor comprising hardware for preprocessing digital images received from the imaging device and storing the digital images in the memory;
a postprocessor comprising hardware arranged to receive digital images and to postprocess the digital images into a viewable form;
wherein the digital image processor is operable in a first mode in which data corresponding to preprocessed images from the preprocessor are directed to the memory, thereby bypassing the postprocessor; and
wherein the digital image processor is operable in a second mode in which data corresponding to the preprocessed images from the preprocessor are directed to the postprocessor for postprocessing and data corresponding to postprocessed images from the postprocessor are directed to the memory. - View Dependent Claims (20, 21, 22, 23, 24)
