Abstract
Abstract An image processing apparatus designates a type of color gamut check method and an output device model for a color gamut check, and sets information indicating a color gamut of the output device model in accordance with a designated type of color gamut check method and a designated output device model. The apparatus then checks, on the basis of the information, whether input color image data is within the color gamut of the designated output device model.

Claim 15
Dependent Claim
21 words
A method according to claim 12, wherein said displaying step displays the result of the checking step visually on a monitor.
Claim 16
Dependent Claim
17 words
A method according to claim 11, wherein the plural color gamut check algorithms have different processing speeds.
Claim 17
Dependent Claim
16 words
A method according to claim 11, wherein the plural color gamut check algorithms have different accuracies.
