Abstract
Abstract An image processing apparatus prevents the misdetermination of a read color and allows correct marker edition. A marker registration circuit reads and register color data marked by a predetermined color marker and a color determination circuit compares the color data registered and the read color data at the reading of the document sheet to determine a color code of the marker color. An area determination circuit determines whether an area being read belongs to a normal area, a line area or a paint area and an output color determination circuit determines a color to be outputted in accordance with the color code and the area being read.
