Control method for pan-tilt-zoom (PTZ) camera, involves changing marking inserted in displayed summary image on display unit to change line of sight and zooming position of PTZ camera

摘要

The method involves generating a summary image, and showing the produced summary image on a display unit (5). A marking is inserted into the displayed summary image to indicate the temporary light or sight or temporary zooming position of a PTZ camera (1). The marking in the displayed summary screen is then changed. The line of sight and zooming position of the PTZ camera is also changed as a reaction to the changed marking. The marking is a frame that can be shifted or drawn up for changing the line of sight and zooming position of the PTZ camera. An independent claim is also included for the control device.
