A vehicular camera is configured to image at least part of surroundings of a vehicle body irradiated by a near-infrared light source attached to the vehicle body, and output a first video imaged. The vehicular camera includes: an illuminance sensor is configured to detect an illuminance of the least part of the surroundings of the vehicle body; and an output circuit configured to output a second video in which at least part of the first video is subjected to a first correction processing, when the near-infrared light source has a first light emission intensity, and output a third video in which at least part of the first video is subjected to a second correction processing different from the first correction processing, when the near-infrared light source has a second light emission intensity larger than the first light emission intensity and the illuminance is smaller than a predetermined value.

Vehicular camera, and video output method

An image capture device of the present invention is provided with: a first brightness adjusting unit which adjusts brightness when capturing an image of a subject; a second brightness adjusting unit which adjusts the brightness of an analog image signal of the subject captured with the brightness adjusted by the first brightness adjusting unit; an A/D conversion unit which subjects the analog image signal with the brightness adjusted by the second brightness adjusting unit to A/D conversion; a third brightness adjusting unit which adjusts the brightness of a digital image signal obtained by the A/D conversion; and a gain-up adjusting unit which raises the gain of a low-illuminance portion of the digital image signal with the brightness adjusted by the third brightness adjusting unit, by means of realtime modification adjustment using a gamma characteristic.
