VEHICLE VISION SYSTEM

摘要

A vehicle viewing system including a camera system for generating a signal corresponding to a scene by integrating light from the scene incident on pixel cells having a variable integration time, a display system for presenting a visual representation of the scene, and a processor system operable to determine the camera system integration time based on brightness levels in the scene. The camera system preferably includes an optical array of photogate CMOS active pixel sensor cells and support electronics implementing a plurality of integration and processing architectures. The camera system may also include digitized output and an input attenuating filter to limit light striking the optical array. The processor system includes an image brightness detector to determine measures of overall image brightness and a display pixel luminance mapping control to determine luminance settings for the display system. The image brightness detector may include circuitry that produces a brightness histogram. The processor system may determine the intensity of the display system based on the brightness of the scene, ambient light levels, and glare on the display. The display system includes a display and a display attenuation filter for limiting the intensity as viewed by the operator.
