Abstract:
A tracking apparatus, comprising:imaging means for generating a plurality of images;driving means for driving said imaging means to effect panning and tilting;imaging object setting means for detecting motion in an image and for setting a portion in said image in which said motion has been detected as an imaging object, said imaging object setting means including motion detection means for calculating a difference value of images of two successive frames generated by said imaging means and for detecting said motion of the image based on the calculated difference value such that said portion in said image in which said motion has been detected is initially set as said imaging object without user manipulation;imaging object detection means for detecting the imaging object set by said imaging object setting means in said plurality of images generated by said imaging means;control means for controlling said driving means so that a position of the imaging object detected by said imaging object detection means coincides with a predetermined reference position of said image generated by said imaging means; andframe display control means for superimposing a frame around said imaging object on said image when said imaging object detection means has detected said imaging object, said frame display control means modifying said frame if said imaging object is no longer detected.
