  • Publication number: 20240267631
    Abstract: In an imaging apparatus, a common region identifier identifies a common region of each of a first image captured by a front monitor camera and a second image captured by a surrounding monitor camera. A difference calculator calculates a target luminance difference between the common region of the first image and the common region of the second image. A luminance adjuster performs, based on the target luminance difference, at least one of (i) a first adjustment of adjusting a luminance of the first image and (ii) a second adjustment of adjusting the at least one imaging parameter of the front monitor camera.

  • 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.
