As a result, there is a problem that the original image and the recorded image recorded on the recording paper are different in appearance.
[0011] In addition, when the undercolor removal process is performed on the pixels included in the predetermined chromaticity range and lightness range centered on the undercolor, regardless of the color mode or the black and white mode, the aesthetics before and after the undercolor removal are produced (also That is, the original image and the appearance of the recorded image) are different

Abstract
An image color decision apparatus according to the present invention includes a ground color decision unit and a target image decision unit. The ground color decision unit decides the presence or absence of a ground color in a target image based on image data concerning the target image, and the ground color decision unit decides the ground color when the target image has the ground color. The target image decision unit uses the decision result of the ground color decision unit to make a color decision of the target image based on the image data concerning the target image.
Description
technical field [0001] The present invention relates to an image judging device and an image color judging method for judging the background color of a target image, and more particularly, to an improvement made so that even if a document has a background color, the color judgment can be performed well. [0002] This application claims Japanese Patent Application Nos. 2006-242189 filed on September 6, 2006, 2006-242193 filed on September 6, 2006, 2007-183147 filed on July 12, 2007, and 2007 Priority No. 2007-183148 filed on July 12, 2007 and incorporated herein by reference in its entirety. Background technique [0003] In general, an apparatus having a color printing function has a color mode for printing on printing paper in color, and a black-and-white mode for printing in black and white (no color, only expressed in grayscale). Print in any processing mode. Normally, the user selects the processing mode. However, there are cases in which printing is performed in a proc...
