  • Patent number: 11780382
    Abstract: A vehicle mountable camera is provided which includes an imaging device, an exposure controller, and an image processor. The imaging device is configured to be installed behind a windshield of a subject vehicle to capture an image of a forward view in front of the subject vehicle. The exposure controller controls the degree of exposure of the imaging device. The image processor executes an image processing operation on the captured image. The camera determines whether a brightness boundary exists in front of the subject vehicle and, when the brightness boundary is determined to exist, controls the exposure of the imaging device and/or adjustment of brightness of the image quickly when the subject vehicle passes the brightness boundary. This minimizes a risk that the captured image may be darkened or brightened suddenly immediately after the subject vehicle moves from a sunny area to a shaded area or vice versa.
