Abstract:
1. 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; 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; and a system bus within the digital image processor, wherein the preprocessor, the postprocessor, and an interface for the memory are coupled to the system bus.
