    摘要： A photoelectric conversion apparatus includes an avalanche photodiode including an anode and a cathode, a switch that is connected to one node of the anode and the cathode, and a power line to which a drive voltage is to be applied, and configured to switch a resistance value between the one node and the power line, and a signal generation unit configured to generate a pulse signal for controlling switching of the switch, wherein a value obtained by dividing the number of the pulse signals in a first exposure period by the first exposure period, and a value obtained by dividing the number of the pulse signals in a second exposure period having a length different from a length of the first exposure period, by the second exposure period are different.

    摘要： An imaging apparatus includes an imaging element including photodiode divided pixels, and a control unit. The control unit performs control to execute first readout in which an addition value of a first pixel and a second pixel constituting a photodiode divided pixel is read out as a pixel value constituting an image and second readout of performing readout in which a value of the first pixel and a value of the second pixel used for phase difference detection can be obtained from a photodiode divided pixel that is not a readout target in the first readout. In this case, the first readout is performed after performing the second readout in one vertical period.

    摘要： Provided are image signal processing apparatuses and methods for operating the same. In an embodiment, the image signal processing apparatus is configured to receive, from an image sensor device, an input image. The apparatus is further configured to perform a binning and crop operation on the input image to generate a first image. The apparatus is further configured to perform a Bayer domain processing on the first image to generate a second image. The apparatus is further configured to perform RGB domain processing on the second image to generate a third image. The apparatus is further configured to perform YUV domain processing on the third image to generate an output image. The YUV domain processing comprises at least one of a spatial de-noising operation, a temporal de-noising operation, a motion compensation operation, a tone mapping operation, a detail enhance operation, and a sharpening operation.
