PURPOSE:To provide an image controller which can set a wide visual field range while securing detection precision. CONSTITUTION:A CPU 51 indicates a visual field direction so that the center point of a chromaky image extracted by a position detection processing part 40 is in the center of the image pickup visual field of an image pickup part. A support mechanism part 14 pans the image pickup part 1 according to an instruction from the CPU 51. Consequently, the chromakey image is put in the image pickup visual field at all times. Therefore, the possibility that malfunction is caused by deviation from the image pickup visual field and the need to widen the visual field angle to prevent the chromakey image from deviating from the image pickup field are eliminated, thus, a video visual field range can be set without causing a decrease in detection precision. |
