Vehicle vision system
First Claim
1. A vehicle viewing system for displaying an image of a scene to a vehicle operator, the system comprising:
- a camera system to generate a signal corresponding to the scene by integrating light from the scene incident on pixel cells, the pixel cells having a variable integration time that sets the length of time during which the pixel cells integrate light despite being exposed to light over a longer period comprising;
an optical sensor operative to produce a digital signal corresponding to the scene, wherein the digital signal comprising a magnitude and a range for each pixel cell, the range indicative of the integration period used by the pixel cell; and
a lens system to focus the image of the scene onto the optical sensor;
a display system to present the image of the scene; and
a processor system in communication with the camera system and the display system, the processor system operable to determine the camera system integration time based on brightness levels in the scene.

Abstract
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 and an input attenuating filter to limit light striking the optical array. The processor system includes an image brightness detector to determine overall image brightness and a display control to determine luminance settings for the display system. 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.
