PURPOSE:To facilitate the checking of a negative, by processing the signals obtained by image picking up plural printing negative films through plural TV cameras to display these signals to a monitor TV and at the same time converting an optional signal into a color different from the original color. CONSTITUTION:The negative films 2-5 correspond to 4 colors Y (yellow), M (magenta), C (cyan) and BL (black) which are arranged on a holding plate 1 and formed into images of desired sizes through zooming 7'-10' to be image picked up through TV cameras 7-10. Thus signals Y, M, C and BL are obtained. The white and black levels are controlled 12 by an electric signal processing circuit 11. Then these 4 signals are amplified by a matrix circuit 13 and converted into 3 primary signals R, G and B. These 3 signals are fed to a monitor TV 14 and synthesized to a color to be displayed. Furthermore the signal supplied from a negative film which produces the signal Y which is hard to check the negative film is converted into a signal of another easy-to-see color and fed to the TV 14. As a result, the priority can be easily detected for the conjecture of each negative film. |
