ABSTRACT:
An electronic camera is adapted for processing images of different resolution to provide a user selectable image record size. A buffer memory is provided for storing color image pixels from a sensor corresponding to at least one image. Processing responsive to a resolution mode switch controls the order in which color image pixels are selected for output storage in both vertical and horizontal directions. The order selected by the resolution switch includes a full resolution mode, and at least one reduced resolution mode in which the low resolution color image pixels are calculated to exactly replicate the pixel geometry of the original CFA image. This simplifies the image processing for the rest of the imaging chain because the same algorithms can be used regardless of the selected image resolution.
