摘要： 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.

摘要： 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.

摘要： An imaging device includes a semiconductor substrate, a first pixel that performs photoelectric conversion, and a first shield. The first pixel includes a first diffusion region that is present in the semiconductor substrate, a first wiring line connected to the first diffusion region, a first transistor, and a first voltage line that makes up at least part of a voltage supply path to a drain or a source of the first transistor. A first signal charge obtained by photoelectric conversion performed by the first pixel flows through the first wiring line. The first signal charge flows into a gate of the first transistor via the first wiring line. Voltages that are different from each other are applied to the first voltage line. A distance between the first voltage line and the first shield is smaller than a distance between the first voltage line and the first wiring line.

摘要： An imaging control device includes a controller and an input section. The controller causes an image sensor to, during at least one first frame period, capture at least one first multiple exposure image by using a first exposure signal that contains a plurality of pulses having a plurality of pulse widths different from one another; the image sensor is configured to capture an image by making multiple exposure. The input section receives the at least one first multiple exposure image. The controller selects one pulse width from the plurality of pulse widths, based on the first multiple exposure image received by the input section and then causes the image sensor to, during a second frame period, capture the image by using a second exposure signal that contains a pulse having the selected pulse width; the second frame period follows the first frame period.
