PURPOSE:To adjust the position of a camera simply, quickly and accurately by inputting lateral and vertical deviation between the optical axis of an optical system and the optical axis of the camera in a CRT controller into an input circuit of a controller from numeric keys or the like. CONSTITUTION:To display a character image (a) at the center of a CRT24 of a CRT controller 16, the optical axis l' of the optical system is coincided with the optical axis of a camera 18. When both optical axis deviate, the character image (a) is memorized at the position biased to one side in an input video RAM20. When the lateral deviation (x) in the optical axis and the vertical deviation (y) in the optical axis are inputted from an input circuit 7 of a controller 25, a system controller 21 commands a camera controller 19 to shift the start position of transferring data to an output video RAM22 from the input video RAM20 by (x) laterally and (y) vertically. |
