Claim One:
1. A video image stabilization system comprising: a camera including an image capturing device configured to capture a video image, said camera having a selectively adjustable field of view; and a processing device operably coupled to said camera wherein said processing device receives signals indicative of the field of view of said camera and images captured by said camera, said processing device automatically tracking movements of at least one object in the images, said processing device determining a stabilizing adjustment for the video image as a function of an unintended change in the field of view of said camera during a time interval between capture of a first image and capture of a second image, the determining being based upon said signals indicative of the field of view and an analysis of said first and second images, the analysis of said first and second images including aligning one of said first and second images with an other of said first and second images based upon said signals indicative of the field of view and determining if said aligned images indicate an occurrence of unintentional camera movement by determining an image difference of said aligned images, said processing device generating a histogram of said image difference of said aligned images and determining whether unintentional camera movement has occurred based upon identifying a maximum peak in said histogram and a location of said maximum peak, and wherein when said maximum peak is not substantially centered on zero, unintentional camera movement is determined to have occurred and wherein determination of said stabilizing adjustment includes identifying adjustments that reduce the image difference.
