摘要

PPROBLEM TO BE SOLVED: To provide an MFP 10 which corrects a color part which appears on a line read from an original image to pure black. PSOLUTION: A black line correction unit 100 is provided with: a color space conversion section 104 which generates a position vector of a three-dimensional color space from pixel values of the respective pixels of primary color image data; a line width detection section 103 which detects line width; a vector conversion section 105 which calculates a plurality of conversion vectors through vector conversion; a selector 106 which selects a conversion vector from candidate vectors according to the line width; a three-dimensional LUT 108 which stores a color vector and a determination value of the three-dimensional color space; a table reading section 107 which reads the determination value corresponding to the conversion vector; and a character area detection section 110 which outputs pure black to the pixels when the determination value is pure black.
