Abstract
The present disclosure relates to imaging systems having functionality for detecting faults in the control and/or readout of the image sensor. In one example, there is a system comprising an image sensor having a plurality of imaging pixels and at least one diagnostic pixel coupled to a reference signal. The system also comprises control and readout circuitry configured to select one or more of the imaging pixels and, for each selected imaging pixel, readout an imaging signal that is indicative of the charge accumulated on the selected imaging pixel, select the at least one diagnostic pixel and, for each selected diagnostic pixel, readout a diagnostic signal that is indicative of the reference signal of the selected diagnostic pixel, and output the diagnostic signal for use in system diagnostics.
