Image capturing apparatus, angle-of-view adjusting method and recording medium

Abstract

In a digital camera, a storing means stores feature quantities of a subject area in an image, and a search point setting means sets a plurality of search points in the subject area. Next, an updating means updates coordinates of the set plurality of search points using random numbers. Then, a weight setting means compares feature quantities of the updated search points with the stored feature quantities, and sets a weight for each search point based on similarity. Next, a sorting means sorts the search points depend on those weight, and a variance acquiring means calculates the variance of the sorted search points. Then, an angle-of-view adjusting means determines the amount of adjustment for the angle-of-view based on the calculated variance.
