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

A dynamic DC offset removal apparatus and a dynamic DC offset removal method capable of accurately estimating a change position of a dynamic DC offset and a DC offset value before the change and a DC offset value after the change, thereby carrying out equalization processing on a reception signal whose dynamic DC offsets are removed, and improving a bit error rate characteristic. In receiverhaving a dynamic DC offset removal apparatus, dynamic DC offset detection sectioncalculates a DC offset value before the change and a DC offset value after the change, and DC offset change timing from the maximum value and minimum value calculated at maximum value search sectionand minimum value search sectionand the first-half mean value, second-half mean value and overall mean value calculated at first-half mean value calculation section, second-half mean value calculation sectionand overall mean value calculation section, and compensation DC offset switching sectionof DC offset removal sectionswitches between the DC offset value before the change and DC offset value after the change based on the DC offset change timing and removes dynamic DC offsets from the reception signal.
