A method for controlling a camera using an image compression algorithm. A motion region and a motionless region are determined with respect to an input image based on a motion vector of a macro block which is for the generation of compressed data from the input image. A center value and a size of a moving object is estimated from the motion region. According to the center value and the size of the moving object, the camera is controlled to track and photograph the moving object. Accordingly, a central processing unit of the moving object tracking system is relieved of substantial processing load, and the processing speed of the system is improved.

1. Field of the Invention
The present invention relates to a system for photographing an object, and more particularly, to a method for controlling a camera with motion information of the object that is obtained during compression of input images.
The above-mentioned objects and features of the present invention will be more apparent from the following detailed description of a preferred embodiment of the present invention when read with reference to the appended drawings, in which:
FIG. 1 is a flowchart illustrating a conventional image compressing method;
FIG. 2 is a flowchart illustrating a conventional method for automatically tracking a moving object by using an image signal;
The present invention will now be described in greater detail with reference to the preferred embodiment illustrated in the accompanying drawings.
FIG. 3 is a block diagram showing a moving object tracking system according to the preferred embodiment of the present invention. The moving object tracking system includes a photographing unit 100, an image compression processing unit 200, a driving unit 300 and a photographing control unit 400.
The photographing unit 100 includes a lens (not shown) and a charge coupled device (not shown), and generates image signals while photographing a monitoring area.
