Abstract
PURPOSE:To obtain a composite image without the sense of incompatibility by obtaining the fluctuation of the average luminance signal level of an image to obtain a maximum area on a screen and the image which becomes a base by making variable continuously the level of the signal for a frame added as a boundary in accordance with the luminance level of a main image. CONSTITUTION:An automatic level control circuit 6 controls a frame signal from a frame signal generating circuit 5 with a direct current component from an integration circuit 3, and changes the level of the frame signal in accordance with the change of the luminance component level of a main picture signal supplied to the integration circuit 3. On the screen of a monitor 11, a main image 12 and a sub-image 14 are displayed while the boundary is provided by a frame of the frame signal, and the images are displayed so that the brightness (luminance) can be changed in accordance with the luminance signal level of the main image in which the frame 14 of the frame signal occupies a main area on the screen. Thus, it can be prevented that it is hard for a user to see the frame 14.
