Abstract
Provided is a camera pan-tilt-zoom (PTZ) control technology in which a PTZ control signal input by a user is output as a graphic UI and the user inputs the PTZ control signal while directly monitoring the graphic UI.A camera PTZ control apparatus includes a UI visualization unit configured to generate a reference mark as a reference for operating the monitored area and generate a graphic output signal which represents a current position mark associated with a current position indicated by the operation unit; a PTZ processor configured to calculate and output a PTZ driving value of a shooting camera based on relative positions of the reference mark and the current position mark; and a camera driving unit configured to output a driving signal for driving a PTZ driving unit of the shooting camera through a communication unit according to the calculated PTZ driving value.
