PURPOSE:To execute gradation correction with table data to match with the characteristic of an image and to optimize the both of a person image and a CG image by setting the data of a data table which are different in the gradation correcting time of the person image and in the gradation correcting time of the computer graphic CG image to a gradation correcting circuit. CONSTITUTION:A person 10 is illuminated by a illumination light source 11 in a studio and directly image-picked up by a color TV camera 12. The person image signal of red, green and blue image-picked up from this camera 12 and a synchronizing signal are outputted. By a timing circuit 13, based on the synchronizing signal, the conversion timing signal of an A/D converter 14 and an address signal at the time of a writing to a frame memory 15 are outputted. By this converter 14, the person image signal of respective colors is converted to a digital signal per color and sent to the frame memory 15 and the image signal of the respective colors is written to a proscribed address. The image signal of the memory 15 and a CG image signal inputted from a floppy 17 are color-corrected by a color correcting circuit 20. |
