  Also, it is determined whether the adjustment of the television camera is performed by the menu control unit of the camera head, the control device connected to the camera head, or the control device via the camera control unit, and the corresponding adjustment menu is determined according to the determination result. Is output.

  Further, the user ID for adjusting the television camera is determined, and the corresponding adjustment menu and the initial value of the adjustment menu are output according to the determination result.

  When the present invention is used, a cameraman at a camera head of a television camera performs an operation for adjusting a viewfinder image to make it easy to adjust a field angle, a focus, and an aperture, and a camera head used by a video engineer at a CCU side for CCU output. Since the corresponding adjustment menu or adjustment menu is switched and output according to the work for performing the video adjustment and the CCU video processing adjustment, the adjustment is easy and the time is short.

  Further, as a result of switching the adjustment menu or the initial value of the adjustment menu for each user ID, the CPU software for each user of the television camera is integrated into the common software, and the CPU software management of the television camera becomes only the common software, which is easy. In particular, bug management and maintenance become easy.

Examples of the present invention will be described below.
FIG. 2 is a simple system diagram of a television camera that implements one embodiment. In the shooting studio 11, a cameraman adjusts the angle of view, focus, and aperture with the viewfinder 4, and the video signal captured by the camera head 1 passes through the cable 10 and passes through the camera control unit (CCU) 6 in the sub adjustment room 12. Are output to the video monitor 9. Further, the video engineer confirms the video adjustment of the camera head and the video processing adjustment of the CCU used for the CCU output by the control device 8 on the video monitor 9.

  FIG. 1 is a block diagram of a television camera that implements an embodiment of the present invention. The CPU 2 in the camera head 1 discriminates the control devices 5 and 8 and identifies the user ID based on transmission / reception data with the CPU 7 of the CCU 6. A remote menu command from the camera head menu control unit 3 and the control device 5 and a remote menu command from the control device 8 are detected via the CPU 7 of the CCU 6, and a video monitor 9 is detected via the viewfinder 4 or the CPU 7 of the CCU 6. Causes each menu to be output.

  FIG. 3 is a flowchart of the CPU 2 in the camera head 1 when the viewfinder image adjustment and the image processing adjustment on the CCU side according to an embodiment of the present invention are executed independently, and FIG. It is an example of the adjustment menu common to invention. In the flowchart of FIG. 3, the ellipse is the start and end, the rectangle is the process, and the rhombus is the determination step. After the start step 21, if the camera head menu control unit 3 is operated in step 25 of the camera head menu control unit operation detection (YES), a viewfinder image adjustment menu as shown in FIG.
