OBJECT AREA TRACKING APPARATUS, CONTROL METHOD, AND PROGRAM OF THE SAME
First Claim
1. An object area tracking apparatus for detecting a target object area from a supplied image and tracking the detected object area, comprising:
- a first detection unit configured to detect a predetermined object area from the image on the basis of a first feature amount;
a second detection unit configured to detect a predetermined object area from the image on the basis of a second feature amount different from the first feature amount; and
a main object determination unit configured to obtain a priority for each of the objects by using a detection result of the first detection unit and a detection result of the second detection unit and determine a main object of a high priority from the objects,wherein for the object which is not detected by the first detection unit and is detected by the second detection unit, the main object determination unit changes the priority in accordance with a detection result of the past of the object in the first detection unit.

Abstract
An object area tracking apparatus has: a face detection unit for detecting a face area on the basis of a feature amount of a face from a supplied image; a person'"'"'s body detection unit for detecting an area of a person'"'"'s body on the basis of a feature amount of the person'"'"'s body; and a main object determination unit for obtaining a priority for each of the objects by using detection results by the face detection unit and the person'"'"'s body detection unit and determining a main object of a high priority, wherein for the object detected only by the person'"'"'s body detection unit, the priority is changed in accordance with a past detection result of the object in the face detection unit.
