  • Patent number: 11681024
    Abstract: An imaging device is described which, in some examples, includes general pixels and phase difference pixels. The general pixels, when operated by control signals, receive light from a subject and generate currents or voltages that are measured; a depth is estimated based on the measurements. The phase difference pixels generate currents based on a switched charge source. Data obtained from the currents generated by the phase difference pixels is used to adjust the control signals and thereby improve an accuracy of the depth estimation.
    Type: Grant

  • Patent number: 11513222
    Abstract: An image sensor includes a plurality of pixels and photo gate controller circuitry. Each pixel may transmit a pixel signal, corresponding to a photoelectric signal, in response to a photo gate signal in a frame. The photo gate controller circuitry may generate photo gate signals and transmit photo gate signals to the pixels. The photo gate controller circuitry includes a first delay circuit configured to transmit first delay clock signals each being delayed with respect to a reference clock signal by a certain amount of time and a second delay circuit configured to transmit second delay clock signals each being delayed with respect to the reference clock signal by a certain amount of time. The pixels are each configured to selectively receive signals, as the photo gate signals, among the delay clock signals output from the first delay circuit and the delay clock signals output from the second delay circuit.
