Abstract
A pixel apparatus may include a pixel circuit and a voltage attenuator. The pixel circuit includes multiple pixels, each pixel including photoelectric conversion element. The pixel circuit is structured to receive incident light and output an output signal having pixel voltages in response to the received incident light. The pixel circuit operates in at least one of a quad mode outputting the output signal based on photocharges from a single photoelectric conversion element only and a multi-sum mode outputting the output signal based on photocharges from multiple photoelectric conversion elements. The voltage attenuator is coupled to the pixel circuit. The voltage attenuator can be enabled, when the pixel circuit operates in the multi-sum mode, to receive the output signal and adjust the pixel voltages of the output signal by a predetermined ratio determined by the multi-sum mode.
