A camera apparatus which makes it possible to perform additional camera control during automatic tracking operation within a range in which the automatic tracking operation can be performed without any trouble. A tracking method-calculating section detects a tracking target through analysis of a picked-up image and calculates first camera control parameters for tracking the tracking target. A camera control request input section obtains second camera control parameters from a camera control request accepted from outside the camera apparatus. A camera control method-calculating section calculates third camera control parameters from the first camera control parameters and the second camera control parameters. Further, a camera control section performs camera control according to the third camera control parameters.
