Method and equipment for monitor calibration and storage medium storing a program for executing the method

A method of detecting the black point of a monitor comprising the steps of:

• calibrating on a computer a gradation component input to a monitor driver by displaying a solid black display area and a gray display area adjacent to one another;
• and
• gradually changing brightness of the gray display area from light to dark or from dark to light,
• wherein a selected one of the solid black display area and the gray display area is surrounded by a non-selected one of the solid black display area and the gray display area to detect a black point of a monitor and the brightness of the solid black display area and the gray display area are periodically exchanged, while the brightness of the gray display area is gradually changed from light to dark or from dark to light.

A monitor calibration equipment for detecting a black point of a monitor display capable of being executed on a computer for calibration of a gradation component input to a monitor driver, comprising:

• display area setting means for setting at least one portion of both a solid back display area and a gray display area on the monitor display so as to be interposed in the other display area;
• solid black display area control means for outputting display output of a minimum brightness to be displayed in the solid black display area set by the display area setting means;
• and
• gray display area control means for outputting display output which brightness is gradually varied from light to dark or from dark to light to be displayed in the gray display area set by the display area setting means to detect a black point of a monitor, wherein the solid black display area control means periodically displays in the solid black display area output equivalent to the display output for the gray display area control means while at the same time the gray display area control means displays in the gray display area display output having the minimum brightness, in order that the brightness of the solid black display area and of the gray display area are periodically exchanged, while the brightness of the gray display area is gradually changed from light to dark or from dark to light.
