Image processing device

Abstract

Abstract PURPOSE:To exactly identify the type (property) of original color picture data with a simple constitution by identifying the character of the original color picture data based on the distribution of frequency histogram. CONSTITUTION:An extracting means extracts information concerning a color at every picture element by executing prescribed arithmetic between elements constituting the original color picture data. An arithmetic means calculates the frequency histogram for the picture in a prescribed area at least concerning the color extracted by the extracting means. Based on the distribution of the frequency histogram calculated by the arithmetic means, an identification means identifies the property of the original color picture data. Thus, the character picture of strong monochromaticity is satisfactorily identified from the other picture.
