ABSTRACT:
An image processing apparatus for measuring concentration of concentration patterns by optical sensors and correcting image information on the basis of a correction value obtained on the basis of measured concentration values has: a measured concentration value obtaining unit which measures the concentration in different concentration patterns by the optical sensors and obtains the measured concentration values; an estimation value obtaining unit which estimates original concentration by an independent component analysis on the basis of the obtained measured concentration values and obtains an estimation value; and a correction value obtaining unit which obtains the correction value for allowing the measured concentration value to approach the obtained estimation value. An influence of color noises is reduced, thereby correcting an image.
