Vehicular vision system

A vehicular vision system, said vehicular vision system comprising:

• a CMOS photosensor array comprising a plurality of photosensor elements;
• wherein said photosensor array is disposed at an interior portion of a vehicle equipped with said vehicular vision system and wherein said photosensor array has a forward field of view to an exterior of the equipped vehicle through a windshield of the equipped vehicle at a windshield area that is swept by a windshield wiper;
• said photosensor array having a field of view forward of the equipped vehicle that is generally in line with the equipped vehicle's primary direction of forward travel;
• a control comprising an image processor, said image processor processing image data captured by said photosensor array;
• and
• wherein said control, responsive to an output of said photosensor array, determines an ambient light level present at the equipped vehicle.

• wherein said control processes image data to determine the presence of an object in said forward field of view of said photosensor array;
• wherein the determined object comprises one of (a) a vehicle, (b) a headlight of an approaching vehicle and (c) a taillight of a leading vehicle;
• wherein, responsive to an output of said control, said vehicular vision system is operable to automatically control an exterior light of the equipped vehicle to limit debilitation of a driver of another vehicle forward of the equipped vehicle;
• and
• wherein at least one of (i) said control analyzes image data captured by photosensor elements where a determined object exterior of the equipped vehicle is present more than said control analyzes image data captured by other photosensor elements where the determined object is not present, (ii) said control, responsive to an output of said photosensor array, determines an ambient light level present at the equipped vehicle, (iii) said photosensor array is operated at a plurality of exposure periods, and (iv) at least said photosensor array is disposed in a module and wherein said module releasably attaches to a mounting element that is attached to the windshield of the equipped vehicle.
