PURPOSE:To obtain an optimum picture even when a camera head is singly used by obtaining automatic set-up function in both a camera head part and a camera control part. CONSTITUTION:When only a camera head part 1 is singly used, video signals R, G and B of the camera head part 1 are taken into an automatic set-up device 3 and here, raster position error and an amplitude error are detected. Then, a correction control signal is calculated by an automatic set-up means and outputted to a video signal processing part 2. The video signal of such a result is inputted again to the automatic set-up device 3 and operation is repeated until the video signal output of the video signal processing part 2 goes to be optimum. |
