PURPOSE:To operate a desired device with high operability just by designating the desired one among those devices projected on a TV camera. CONSTITUTION:An intra-video position designating means 7 designates a point position of a desired device to be operated and projected on a TV camera and at the same time outputs the plane coordinate value of the designated point detected on a video. An area coordinate value storage means 8 stores the area coordinate value to prescribe the tanges of plural areas which are previously decided in the video. Then a designated switch deciding means 9 outputs the deciding signal of the prescribed area when the plane coordinate value detected by the means 7 is kept within the range of the prescribed area. A corresponding device designating means 10 receives the deciding signal and outputs a signal to operate the device decided in response to the relevant area. Thus it is not needed to previously store a device code and an operation code nor to designate a device and an operation through the complicated operations. |
