Abstract: An imaging device includes a first pixel, a second pixel, and a correction circuit. First signals respectively corresponding to the first pixel and the second pixel are input to the correction circuit. The correction circuit outputs second signals in response to the first signals. Each of the first pixel and the second pixel includes a photoelectric converter, a charge storage region, and a capacitance circuit. The photoelectric converter converts light into signal charges. The charge storage region stores the signal charges. The capacitance circuit varies a capacitance value of the charge storage region in response to a potential of the charge storage region. The correction circuit corrects the first signal of at least one of the first pixel or the second pixel to the second signal in a case where the same amount of light is incident on the first pixel and the second pixel.

Abstract: An imaging device 100 includes a pixel array PA. A first period, a third period, and a second period appear in this order in a first frame. During the first period, pixel signal readout is performed on a first row in the pixel array PA. During the second period, pixel signal readout is performed on a second row in the pixel array PA. Each of the first period and the second period is a high-sensitivity exposure period. The third period is a low-sensitivity exposure period.

Abstract: An image generation device includes a receiver and a controller. The receiver receives travel information about the travel state of a movable-body apparatus. The controller selects, based on the travel information, a first partial region from an entirety of a plurality of pixels of an image sensor or an entirety of image data captured by the image sensor, and generates image data in which a region other than the first partial region has a resolution lower than the resolution of the first partial region. The image sensor is to be mounted to the movable-body apparatus and is configured to capture an area in a traveling direction of the movable-body apparatus.
