Abstract: A method and an apparatus for tracking an object by using an active camera are provided to obtain an image tracking a moving object and coordinate information of the object from an inputted image, and implement the same simply with hardware. A camera image controller(110) outputs image information corresponding to an image inputted from a camera(10). An image storage memory(120) stores the image information. A background compensator(130) analyzes one or more image information stored in the image storage memory and compensates a change in a background according to the motion of the camera. An image subtracting unit(140) performs subtracting between a plurality of image information compensated by the background compensator. A particle filter(150) tracks an object by using the subtracted image. A camera motion controller(160) controls motion of the camera based on the object tracking results of the particle filter.
