Abstract
An electronic device includes an array of image pixels, with the array of image pixels having inputs coupled to control lines and outputs coupled to output lines, and at least one array of dummy pixels, with the at least one array of dummy pixels having inputs coupled to the control lines. Each dummy pixel of the at least one array of dummy pixels is configured to provide a certain output signal in an absence of a fault with at least one of the control lines or of a fault with at least one of the output lines, such that a lack of output of the certain output signal by one or more of the dummy pixels of the at least one array of dummy pixels indicates the fault.
