Abstract
A vehicular vision system comprises a photosensor array comprising a plurality of photosensor elements arranged in a predefined arrangement. The photosensor array has a field of view forward of the vehicle that is generally in line with the vehicle'"'"'s primary direction of forward travel. The photosensor array captures an image of at least one item of interest exterior the vehicle within its forward field of view. A control is responsive to an output of the photosensor array. Preferably, the control analyzes particular groupings of photosensor elements of the photosensor array while ignoring other particular groupings of photosensor elements of the photosensor array so as to determine at least one of presence, size, shape, contour and motion of the at least one item of interest exterior the vehicle.
