Automatic Headlamp Control System
First Claim
1. A vehicular imaging system comprising:
- a photosensor array comprising a plurality of photosensor elements, said photosensor array having a field of view forward of the vehicle that is generally in line with the vehicle'"'"'s primary direction of forward travel, said photosensor array capturing images of an area encompassed by said forward field of view;
a control responsive to an output of said photosensor array;
said control processing an image data set indicative of captured images;
wherein said control processes a reduced image data set of said image data set to determine whether an object of interest is within a target zone of said captured image, said reduced image data set being representative of a portion of said captured images as captured by a particular grouping of said photosensor elements; and
wherein said control adjusts said reduced image data set so as to be representative of a portion of said captured images as captured by a different particular grouping of said photosensor elements, said control adjusting said reduced image data set in response to a determination of a change in a focus of expansion of said captured images.

Abstract
A vehicular imaging system includes a forward facing photosensor array and a control responsive to the photosensor array. The control processes an image data set indicative of captured images, and the control processes a reduced image data set of the image data set to determine whether an object of interest is within a target zone of the captured image. The reduced image data set is representative of a portion of the captured images as captured by a particular grouping of the photosensor elements. The control adjusts the reduced image data set so as to be representative of a portion of the captured images as captured by a different particular grouping of the photosensor elements, and adjusts the reduced image data set in response to a determination of a change in a focus of expansion of the captured images.
