Abstract
Testing of control wires of a pixel array of an image sensor is performed by applying a signal transition to a control wire and detecting, based on a voltage signal detected on the control wire, the duration of at least part of the signal transition on the control wire. An electrical fault in the control wire is indicated based on a comparison of the detected duration to a threshold.
