A reference picture being as a reference of the replacement area, the reference position of the replacement area and the size of the replacement area has been memorized. Moreover, a replacing LOGO picture has also been memorized. A two dimensional movement amount of a camera is detected by a rotary encoder set on the pan head of the camera, and the detected movement amount is outputted as a movement information. In the picture synthesis device, an address of the reference position of the replacement area in the present picture is calculated based on the movement information, and the replacement area is detected with this address as reference. Then, a key signal indicating a picture in which the present picture and the reference picture within the replacement area are identical or different, and an identical portion between the present picture and the reference picture is replaced with a LOGO picture corresponding to the foregoing identical portion out of the LOGO picture based on this key signal.

Picture replacement system and method of the same

A picture replacement system for replacing a specified area of an original picture, with a desired picture comprising at least one camera for shooting an original picture of the subject; at least one irradiation unit for radiating a specified area of the subject with a predetermined invisible light ray; a picture generation unit for generating a desired picture that matches a size of the specified area; a detection unit for detecting the invisible light ray reflecting from the specified area that has passed around an obstruction in front of the specified area of the subject without being obstructed; a key signal generation unit for generating a key signal indicating a replacement area of the original picture based on a detection result of the detection unit; and a replacement unit for replacing the specified area within the replacement area with a desired picture corresponding to the key signal indicating the replacement area.
