In a situation where information indicating whether or not a color is capable of being reproduced by an output device which is to output the entered image data is held by a three-dimensional LUT, information indicative of a color incapable of being reproduced is held on at least the boundary surface

In a situation where information indicating whether or not a color is capable of being reproduced by an output device which is to output the entered image data is held by a three-dimensional LUT, information indicative of a color incapable of being reproduced is held on at least the boundary surfaces of the LUT. By referring to the LUT, it is judged whether or not a color expressed by the entered image data is capable of being reproduced by the output device.

[ What is claimed is:] [6.] An image processing method comprising the steps of:providing a look-up table that stores data indicating whether or not each of a plurality of representative points lies within a color-reproduction range of an output device;entering image data having a plurality of color components; andperforming interpolation processing by referring to the look-up table in accordance with the entered image data, and judging whether or not the entered image data lies within the color-reproduction range of the output device based on output data provided by the interpolation processing,wherein the look-up table stores data representative of all points located at sides of a solid comprised by the plurality of color components and which are out of the color-reproduction range of the output device.
