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.

Abstract: An imaging device includes: a plurality of pixels arrayed in a matrix, the plurality of pixels respectively including photoelectric converters that convert light into signal charge and charge accumulators that accumulate the signal charge; and a control circuit. The control circuit causes pixels included in the plurality of pixels and belonging to at least one row to sequentially perform, for each row or for two or more rows at a time, a reset operation for initializing potentials of the charge accumulators, before receiving a trigger signal for giving an instruction for starting exposure, and causes, after receiving the trigger signal, the plurality of pixels to simultaneously perform an exposure operation for accumulating the signal charge in the charge accumulators without causing the pixels included in the plurality of pixels and belonging to at least one row to perform the reset operation.

Abstract: 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.
