  • Patent number: 10819928
    Abstract: An imaging system includes an imaging apparatus that is mounted on a vehicle and generates an image by imaging an area around the vehicle, and a processing apparatus that is mounted on the vehicle. The imaging apparatus includes a plurality of pixels. A control unit controls exposure by each of the plurality of pixels, and a processing unit executes a predetermined test. The control unit controls exposure so that reading of a pixel signal is started in a second period after the completion of reading of a pixel signal in a first period. The processing unit executes a predetermined test in a third period, the third period is between the reading of the pixel signal in the first period and the reading of the pixel signal in the second period. The processing apparatus restricts a function of controlling the vehicle based on a result of the predetermined test.
