ABSTRACT:
The image processing apparatus comprises: a pixel train setting unit for setting a pixel train; a moving average calculating unit for estimating the intensity of light illuminating the object as a moving average of luminance of the pixel train; a reflectance calculating unit for converting the luminance of the pixel into reflectance, with the luminance of the pixel divided by the estimated intensity of light; a digitizing unit for digitizing the reflectance of the pixel; an edge detecting means for detecting an edge at which the luminance of the image changes sharply; and a comparing means for comparing the digitized reflectance signal with the edge signal to detect a boundary of regions having different luminance from each other, to eliminate it from the digitized reflectance signal for being a false edge.
