PURPOSE:To display a distribution of contact pressure by equalizers by obtaining a binary-level analog signal from an analog signal corresponding to color density and an analog signal corresponding to a sample picture of density. CONSTITUTION:The surface of a film 5 on which a pattern picture 6 is drawn is scanned by an image pickup tube 11 together with an array of color density samples 7a-7f to obtain the 1st analog signal V1 corresponding to variation in the color density of the pattern 6 and the 2nd analog signal V2 corresponding to the samples 7a-7f. Those are inputted to an A/D converter 13 and converted into a digital signal, which is inputted to a picture processor 16 and stored in a memory 14. Then, addresses wherein the same values as the color density values of the samples 7a-7b are checked to perform conversion to picture data, and a D/A converter 23 performs conversion to the 3rd analog video signal V3. The signal with this signal V3 of binary level is inputted to a display 18 to display an image showing the equalizer distribution of contact pressure on a display screen 19. |
