PURPOSE:To obtain a natural condition by suitably operating the color processing of a boundary part at the time of a color adjustment and a picture synthesis. and operating the color processing of the boundary part at the time of detecting the presence of a specific color deviation phenomenon by an image scanner. CONSTITUTION:At the time of the color adjustment, the color C14 of a boundary part 3 between an object part 2 and a background part 1 is prepared by the additive color mixing processing of the RGB signal of the new color C4 of the object part 2 and the RGB signal of the existing color C1 of the background part 1. And also, at the time of the picture synthesis, the color C24 of the boundary part 3 between the object part 2 and a background part 4 is prepared by the additive color mixing processing of the RGB signal of the existing color C2 of the object part 2 and the RGB signal of the new color C4 of the background part 4. As for the additive color mixture, the ratio of the mixture of the object color C2 with the background color C1 to the boundary color C12 before the color adjustment or the picture synthesis is searched, and the boundary color C14 due to the mixture of the new objective color C4 with the background color C1 at the time of the color adjustment, or the boundary C24 due to the mixture of the new background color C4 with the object color C2 to be synthesized at the time of the picture synthesis, are calculated according to the pertinent ratio. |
