Image photographing apparatus and method of controlling the same
First Claim
Patent Images
1. A method of controlling an image photographing apparatus, the method comprising:
- determining a motion vector of a subject in a photographing region of an image sensor of the image photographing apparatus when a moving image is photographed using the image sensor;
determining whether a non-viewable pixel region of the image sensor is present in the direction of the motion vector; and
moving the photographing region to the non-viewable pixel region within the entire region of the image sensor.

Abstract
A method of controlling an image photographing apparatus to track a subject using a non-viewable pixel region of an image sensor includes detecting a motion vector of a subject when a moving image is photographed, determining whether a non-viewable pixel region of an image sensor is present in the direction of the detected motion vector of the subject, and moving a photographing region to the non-viewable pixel region so as to track the motion of the subject. Accordingly, the moving subject may be tracked within a range of a predetermined Field of View (FOV) of the image photographing apparatus without an additional hardware system.
