APPARATUS AND METHOD FOR ACTIVELY TRACKING MULTIPLE MOVING OBJECTS USING A MONITORING CAMERA
First Claim
1. An apparatus for actively tracking an object, the apparatus comprising:
- a camera unit;
a motor drive for changing a shooting direction of the camera unit; and
a controller for acquiring a first comparative image and a second comparative image in sequence using the camera unit, comparing the first comparative image with the second comparative image, detecting a moving direction and a speed of an identical object existing in the first and second comparative images, determining an estimated location of the object after receipt of the second comparative image based on the detected moving direction and speed, and enlarging and capturing the object in the estimated location of the object.

Abstract
An apparatus for actively tracking an object is provided. The apparatus includes a camera unit; a motor drive for changing a shooting direction of the camera unit; and a controller for acquiring a first comparative image and a second comparative image in sequence using the camera unit, comparing the first comparative image with the second comparative image, detecting a moving direction and a speed of an identical object existing in the first and second comparative images, determining an estimated location of the object after receipt of the second comparative image based on the detected moving direction and speed, and enlarging and capturing the object in the estimated location of the object.

6. An apparatus for actively tracking an object, the apparatus comprising:
-
a camera unit; a motor drive for changing a shooting direction of the camera unit; and a controller for acquiring a first comparative image and a second comparative image in sequence using the camera unit, dividing each of the first and second comparative images into a plurality of sectors, comparing a first sector in the first comparative image with a second sector in the second comparative image, which corresponds to the first sector, detecting a moving direction and a speed of an identical object existing in the first and second sectors, determining an estimated location of the object after receipt of the second comparative image based on the detected moving direction and speed, enlarging a sector corresponding to the estimated location of the object among the plurality of sectors, and capturing a target image. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for actively tracking an object, the method comprising:
-
(1) acquiring a first comparative image from an image formed on an imaging device; (2) acquiring a second comparative image after acquisition of the first comparative image; (3) comparing the first comparative image with the second comparative image, and detecting a moving direction and a speed of an identical object existing in the first and second comparative images; (4) determining an estimated location of the object after receipt of the second comparative image based on the detected moving direction and speed; and (5) enlarging and capturing the object in the estimated location of the object. - View Dependent Claims (14, 15)

16. A method for actively tracking an object, the method comprising:
-
(1) acquiring a first comparative image using a camera unit; (2) acquiring a second comparative image using the camera unit; (3) dividing each of the first and second comparative images into a plurality of sectors, comparing a first sector in the first comparative image with a second sector in the second comparative image, which corresponds to the first sector, and detecting a moving direction and a speed of an identical object exiting in the first and second sectors; (4) determining an estimated location of the object after receipt of the second comparative image based on the detected moving direction and speed; and (5) enlarging a sector corresponding to the estimated location of the object among the plurality of sectors, and capturing a target image. - View Dependent Claims (17, 18, 19, 20)
