Abstract
Abstract The name of one camera to be controlled is displayed in a camera-name display field of a camera control interface displayed on a screen. When a prescribed operation is performed, the names of cameras capable of being controlled are sorted in accordance with the degrees of frequency of use thereof so that the camera names are displayed in a list in order of decreasing frequency of use. By selecting one of the displayed camera names, the camera is selected as the camera to be controlled.
