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: A camera system including an imaging device that captures a first image by a normal exposure including only one exposure and that captures a second image by a multiple exposure including a plurality of exposures; and a control circuit. The the imaging device captures the second image in a first frame period, and the control circuit determines, based on the second image captured in the first frame period, whether to capture an image by the normal exposure or capture an image by the multiple exposure in a second frame period following the first frame period.

Abstract: An imaging device includes a pixel including a photoelectric converter, where the pixel captures first data in a first exposure period and captures second data in a second exposure period different from the first exposure period, the first exposure period and the second exposure period being included in a frame period. A sensitivity of the photoelectric converter in the first exposure period is different from a sensitivity of the photoelectric converter in the second exposure period, and the imaging device generates multiple-exposure image data including at least the first data and the second data.

Abstract: An imaging device includes: unit pixel cells each including first and second electrodes, a photoelectric conversion layer therebetween, a charge accumulation region, and a signal detection circuit; and a voltage supply circuit, the voltage supply circuit supplying a first voltage to the second electrode in an exposure period. The start and end of the exposure period is common to the unit pixel cells. The photoelectric conversion layer has a photocurrent characteristic including first to third voltage ranges. In the third voltage range between the first and second voltage ranges, an absolute value of a rate of change of a current density relative to a bias voltage is less than in the first and second voltage ranges. The voltage supply circuit supplies a second voltage to the second electrode in a non-exposure period such that the bias voltage applied to the photoelectric conversion layer falls within the third voltage range.

Abstract: An imaging device includes a pixel. The pixel includes: a first electrode; a second electrode facing the first electrode; a photoelectric conversion layer between the first electrode and the second electrode, the photoelectric conversion layer converting light into signal charge; and a charge accumulation region coupled to the second electrode, the charge accumulation region accumulating the signal charge. The pixel captures first data in a first exposure period and captures second data in a second exposure period different from the first exposure period, the first exposure period and the second exposure period being included in a frame period. A length of the first exposure period is different from a length of the second exposure period. The imaging device generates multiple-exposure image data including at least the first data and the second data.

Abstract: An image generation device includes a first reception unit and a control unit. The first reception unit receives travel information about the travel state of a moving body. The control unit sets, based on the travel information, a multiple-exposure region in an imaging region of an image sensor used on the moving body, and generates image data in which the multiple-exposure region in the imaging region is formed through a multiple exposure and a region other than the multiple-exposure region is not formed through the multiple exposure.

Abstract: An electronic device including: a photosensitive layer that converts incident light into a signal charge; a first electrode that collects the signal charge; and a first carrier blocking layer between the photosensitive layer and the first electrode. The carrier blocking layer is configured to block a carrier a polarity of which is different from that of the signal charge. Under a first range of biases on the electronic device, the photosensitive layer is configured to generate photocurrent while illuminated. Under a second range of biases on the electronic device, the photosensitive layer is configured to generate lower photocurrent while illuminated compared to under the first range of biases.

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.
