PROBLEM TO BE SOLVED: To create a color sample for checking the appearance of color having a spatial distribution in an actual environment.SOLUTION: A storage medium (ROM 22) is a computer readable storage medium which records image data generated in a two-dimensional closed region as a color sample, a spatial distribution related to a hue value representing each pixel of the image data exists in a pseudo random number distribution kept within a certain numerical range, and an amplitude spectrum in a spatial frequency space related to each hue value is almost proportional to an inverse number of a space frequency.SELECTED DRAWING: Figure 8 |
