Vehicle vision system with enhanced functionality
First Claim
1. A vision system for a vehicle, said vision system comprising:
- a camera disposed at a vehicle equipped with said vision system, wherein said camera has a field of view at least forward of the equipped vehicle;
a control comprising an image processor for processing image data captured by said camera;
wherein, via processing by said image processor of image data captured by said camera, said control determines position of the sun relative to a driver'"'"'s forward view through a windshield of the equipped vehicle;
wherein, responsive to determining, via processing by said image processor of image data captured by said camera, that the position of the sun is likely to hinder the driver'"'"'s forward view through the windshield, said control controls a sun visor of the equipped vehicle to limit sunlight from reaching the driver'"'"'s eyes; and
wherein said control determines that the position of the sun is likely to hinder the driver'"'"'s forward view through the windshield at least in part responsive to detection of light in a range of colors that is indicative of sunlight from the sun.

Abstract
A vision system for a vehicle includes a camera disposed at a vehicle equipped with said vision system, the camera having a field of view at least forward of the equipped vehicle. A control includes an image processor for processing image data captured by the camera. The control, via processing by the image processor of image data captured by the camera, determines position of the sun relative to a driver'"'"'s forward view through the windshield. Responsive to determining, via processing by the image processor of image data captured by the camera, that the position of the sun is likely to hinder the driver'"'"'s forward view through the windshield, the control controls a sun visor of the equipped vehicle to limit sunlight from reaching the driver'"'"'s eyes.

14. A vision system for a vehicle, said vision system comprising:
-
a camera disposed at a vehicle equipped with said vision system, wherein said camera has a field of view at least forward of the equipped vehicle; a control comprising an image processor for processing image data captured by said camera; wherein, via processing by said image processor of image data captured by said camera, said control determines position of the sun relative to a driver'"'"'s forward view through a windshield of the equipped vehicle; wherein, responsive to determining, via processing by said image processor of image data captured by said camera, that the position of the sun is likely to hinder the driver'"'"'s forward view through the windshield, said control controls a sun visor of the equipped vehicle to limit sunlight from reaching the driver'"'"'s eyes; and wherein said control determines that the position of the sun is likely to hinder the driver'"'"'s forward view through the windshield at least in part responsive to (i) an intensity of ambient light at the equipped vehicle and (ii) detection, via processing by said image processor of image data captured by said camera, of a brightness level above a threshold level that is indicative of sunlight from the sun. - View Dependent Claims (15, 16)

17. A vision system for a vehicle, said vision system comprising:
-
a camera disposed at a vehicle equipped with said vision system, wherein said camera has a field of view at least forward of the equipped vehicle; wherein said camera is disposed at a windshield of the equipped vehicle and views forward through the windshield and ahead of the equipped vehicle; a control comprising an image processor for processing image data captured by said camera; wherein, via processing by said image processor of image data captured by said camera, said control determines position of the sun relative to a driver'"'"'s forward view through the windshield; wherein, responsive to determining, via processing by said image processor of image data captured by said camera, that the position of the sun is likely to hinder the driver'"'"'s forward view through the windshield, said control controls a sun visor of the equipped vehicle to limit sunlight from reaching the driver'"'"'s eyes; wherein said control determines that the position of the sun is likely to hinder the driver'"'"'s forward view through the windshield at least in part responsive to detection of light in a range of colors that is indicative of sunlight from the sun; and wherein said sun visor comprises one of (i) an adjustable sun visor that is adjustable between a stowed orientation, where said sun visor is disposed along a headliner of the equipped vehicle, and a use orientation, where said sun visor is disposed at least partially in the driver'"'"'s forward view through the windshield of the equipped vehicle, and (ii) a variable light transmissive portion of the windshield of the equipped vehicle that is adjustable between a transmissive state, where the variable light transmissive portion of the windshield is transmissive to visible light, and a darkened state, where the variable light transmissive portion of the windshield attenuates transmission of visible light more than when in the transmissive state. - View Dependent Claims (18, 19)
