Patent ID: 7236644

Claim:
An image processing apparatus of performing a process for recording a target image on a recording medium at unit of a pixel by means of a plurality of recording elements, wherein the plurality of recording elements respectively use a plurality of recording agents of different densities with respect to a same color, said apparatus comprising: storage means for storing a table of ink superimposed printing, the table including pattern information about use/no use of each of said recording agents in said recording elements for each gradation level and a density of gradation expressed by the corresponding pattern information for each gradation level; measurement means for measuring a density of a predetermined image recorded in advance on said recording medium on the basis of the table; and correction means for correcting the table in said storage means on the basis of a measured result of said measurement means, wherein the table is corrected by obtaining a difference between the density of gradation and the measured density for each gradation level and changing the pattern information based on magnitude of the difference for each gradation level.
