摘要： An image capturing apparatus includes a plurality of photoelectric conversion elements, a first selection unit, and a second selection unit. Each of the photoelectric conversion elements includes an avalanche diode and a counter. The photoelectric conversion elements have a first photoelectric conversion element and a second photoelectric conversion element. The first selection unit controls the first photoelectric conversion element. The second selection unit controls the second photoelectric conversion element. The first and second selection units are controlled by a first control line and a second control line. In a first mode, the second selection unit controls the second photoelectric conversion element to be brought into a state where no signal is read from the second photoelectric conversion element. In a second mode, the second selection unit controls the second photoelectric conversion element to be brought into a state where a signal is read from the second photoelectric conversion element.

摘要： A system for power efficient image acquisition is configurable to capture, using an image sensor, a plurality of partial image frames including at least a first partial image frame and a second partial image frame. The first partial image frame is captured at a first timepoint using a first subset of image sensing pixels of the plurality of image sensing pixels of the image sensor. The second partial image frame is captured at a second timepoint using a second subset of image sensing pixels of the plurality of image sensing pixels of the image sensor. The second subset of image sensing pixels includes different image sensing pixels than the first subset of image sensing pixels, and the second timepoint is temporally subsequent to the first timepoint. The system is configurable to generate a composite image frame based on the plurality of partial image frames.
