Calibration method and apparatus for display devices.

摘要

A display control unit (31) reads out a dot pattern image from a pattern image data holding unit (30) and a grayscale pattern image containing a plurality of grayscale patches of gradually varying gray scale from a grayscale image data holding unit (32), and presents the thus readout images for display on a display device (14). A user selects the grayscale patch having brightness closest to the brightness of the dot pattern image by operating a selection unit (16). Based on the selection, a gamma coefficient value is calculated by a gamma coefficient value calculation unit (36), and based on this gamma coefficient value, a profile creation unit (38) modifies an International Color Consortium (ICC) profile held in a common information holding unit (39) and thus creates a customized ICC profile. Such apparatus can create an ICC profile in a simple manner without using a specialized measuring instrument. <IMAGE>
