ABSTRACT:
An application-specific integrated circuit (ASIC) that is programmable for provision of timing and control of imaging signals, including genclock and defective pixel correction function. The ASIC stores information regarding the existence of a next closely spaced defective pixel as the least significant bits of an n-bit words address of a previous defective pixel and compares only the X location information for the next pixel.
