PURPOSE:To provide the image controller which suppresses malfunction in the case wherein the body of the same color with an object to be detected is put in a picked-up image. CONSTITUTION:A position detection processing part 40 while detecting a chromakey image of a specific color based on the chromakey detection signal CRO supplied from a video signal processing part 20 according to a detection frame generates a new detection frame corresponding to the shape of the detected chromakey image. A CPU 51 controls the display mode of a computer image displayed on a display screen according to the display position of the chromakey image detected through the generated detection frame. Consequently, the CPU 51 performs the chromakey detection according to the detection frame corresponding to the shape of the chromakey image, so even when the body of the same color with the detection object enters the picked up image, the possibility that the body is detected as the chromakey image by mistake is a little and the malfunction can be suppressed. |
