Claim 20:
21. An electronic device, comprising:
an array of image pixels having inputs coupled to first selection tracks and outputs coupled to first output tracks;
an array of test pixels having inputs coupled to the first selection tracks and outputs coupled to second output tracks; and
a processor coupled to receive output signals on the first and second output tracks;
wherein each test pixel of the array of test pixels is configured to generate the output signal at one of only two possible logic values set by a circuit connection of the test pixel in the absence of a selection track defect or output track defect; and
wherein the processor is configured to identify existence of the selection track defect or output track defect in response to the output signal received from one or a plurality of the test pixels having a value other than said one of the two possible logic values set by the circuit connection.
