ABSTRACT:
An image signal processor for processing a received image signal. The received image signal can be at least one of an analog image signal and a digital image signal. The processor converts the analog image signal into first digital image data and converts the digital image signal to second digital image data. The processor selects at least one of the first and second digital image data as input image data. The input image data is then decode-processed based upon a selected at least one of a plurality of processing programs. The selected at least one processing program corresponds to the selected at least one of the first and second digital image data.
