Abstract
Abstract The invention includes a digital storage device detachably connectable to an electronic camera of the type that generates an image signal and provides the image signal to an output connection on the camera. The digital storage device includes an algorithm memory for storing a plurality of algorithms for processing the image signal, a signal interface for transmitting signals between the storage device and the output connection on the camera, and a processor responsive to write command signals from the camera provided through the signal interface for selecting one of the algorithms stored in the algorithm memory. The processor then generates a processed image signal by applying the selected algorithm to the image signal provided through the interface, and stores the processed image signal in an image memory section in the storage device.
