Patent ID: 7456998

Claim:
An image processing apparatus comprising: color density decomposing means for decomposing a value of a color material of high density of a first hue serving as a decomposition target into a combination of the value of the high-density color material of the first hue and a value of a low-density color material of the first hue by using a value obtained by color-measuring a patch in which the high-density color material of the first hue and the low-density color material of the first hue are combined; comparing means for comparing a color measurement value of a patch formed by using the value of the high-density color material serving as a decomposition target with a color measurement value of a patch formed by using the values of the high-density color material and the low-density color material which are formed by said color density decomposing means decomposing the high-density color material; and color correcting means for correcting a color deviation of the first hue as between before and after the color density decomposition by said color density decomposing means by adjusting an amount of a color material of a second hue that is different from the first hue, on the basis of a result of the comparison by said comparing means.
