An imaging device includes a plurality of pixel sensors that respond to incident light. At least one drive-sense circuit is configured to generating a sensed signal corresponding to one of the plurality of pixel sensors. The at least one drive-sense circuit includes: a first conversion circuit configured to convert, a receive signal component of a sensor signal corresponding to the one of the plurality of pixel sensors into the sensed signal, wherein the sensed signal indicates a change in a capacitance associated with the one of the plurality of pixel sensors; a second conversion circuit configured to generate, based on the sensed signal, a drive signal component of the sensor signal corresponding to the one of the plurality of pixel sensors. The at least one drive-sense circuit is further configured to generate a plurality of other sensed signals corresponding to other ones of the plurality of pixel sensors for the other ones of the plurality of pixel sensors. A graphics processing module is configured to generate image data based on the sensed signal and the plurality of other sensed signals.
