Abstract

A color adjustment system for a display device includes a computer device, and a display device for displaying an image. The display device selectably displays a plurality of color temperature color presets. The computer device makes a white point adjustment to the display device, based on a color temperature color preset selected from among the plurality of color temperature color presets by a selecting operation from the computer device.

said printed material, with an image printed thereon, being used in making a white point adjustment to the display device,

said image including at least:

a white portion;

a shadow portion of an achromatic color continuously changing from white to black;

a black portion; and

a gray portion,

wherein the percentage of said white portion and said shadow portion in said image is greater than 10%,

wherein the percentage of said gray portion in said image is greater than 30%, and

wherein the percentage of said black portion in said image is greater than 2%,

wherein the color adjustment system is further configured to install said generated color profile into a management folder, and prior to the installation, a comparison is made between the white point and a gamma value of existing profile in the management folder and the white point and the gamma value of the generated color profile, and based on a determination that these values are within a predetermined limit, the existing profile is specified as a default color profile so as to be used as the color profile associated with the display device.
