Abstract
A device for judging the type of color of a document judges in real time on the basis of read data whether or not a document is a color document or a black-and-white document. It is judged whether or not each pixel is a color pixel on the basis of the read data. When not less than a predetermined number of color pixels are continuously detected, the presence of a color block is detected. When there are not less than a predetermined number of color blocks in one line or there is a relatively long color block having not less than a constant length in one line, it is judged that the line is a color line. When not less than a predetermined number of color lines, for example, 100 color lines are detected, it is judged that the document is a color document.
