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

A monitor calibration method for aiding a viewer in detecting the black point of a monitor, comprising the steps of:

• 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 non-selected one of the solid black display area and the gray display area.

A monitor calibration equipment for aiding a viewer in detecting a black point of a monitor display, comprising:

• display area setting means for setting at least one portion of both a solid black 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.

A monitor calibration equipment for adjacently displaying a solid black display area and a gray display area on a monitor display and for aiding a viewer in detecting a black point of a monitor display by gradually changing brightness of the gray display area from dark to light or from light to dark, which equipment comprises:

• display area setting means for setting one of either the solid black display area or the gray display area so as to be surrounded by the other display area on the monitor display;
• 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 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.

A monitor calibration equipment for aiding a viewer in determining a black point of a monitor display, which equipment comprises:

• display area setting means for adjacently setting a first gray display area and a second gray display area on the monitor display;
• first gray display area control means for outputting display output to the first gray display area set by the display area setting means;
• second gray display area control means for outputting display output to the second gray display area set by the display area setting means which output is different from the display output of the first gray display area control means;
• and
• display output control means for controlling display output of the first gray display area control means and display output of the second gray display area control means so that the display output for both is changed from light to dark while the difference in the display outputs is maintained or gradually decreased, or so that the display output for both is changed from dark to light while the difference in the display outputs is maintained or gradually increased.
