ABSTRACT:
An image sensing chip includes an active pixel sensor array including a plurality of pixels arranged in rows and columns. A built in self test circuit is coupled to the active pixel sensor array. The built in self test circuit includes an output port adapted to be coupled to external circuitry and the built in self test circuit is operable to test the active pixel sensor array and provide the results of the test on the output port.
