Abstract
Various embodiments comprise apparatuses and methods including an image sensor. In one example, the image sensor includes a read-out integrated circuit, a plurality of pixel electrodes, an optically sensitive layer, and a top electrical contact. In a first low-power mode, electrical current passing through the top electrical contact is configured to be sensed, and independent currents passing through the plurality of pixel electrodes are configured not to be sensed independently. In a second high-resolution mode, independent currents passing through the plurality of pixel electrodes are configured to be sensed independently. Additional methods and apparatuses are described.
