  • Test system for verification of front camera lighting features
    Patent number: 10870400
    Abstract: A method of testing a vehicular camera includes providing a camera that has a field of view, providing a display screen that displays video images, providing an LED matrix having a plurality of LEDs that emit patterns of light of different colors, and providing a partially light reflecting and partially light transmitting mirror in the field of view of the camera and between the camera and the display screen or between the camera and the LED matrix. A simulator control generates video control signals and LED control signals. Displayed video images either pass through the mirror or reflect off the mirror to be imaged by the camera. The emitted patterns of light either reflect off the mirror or pass through the mirror to be imaged by the camera. A processor may process captured image data to determine whether or not the camera is functioning properly.
