  • Color calibration of display devices
    Patent number: 5483259
    Abstract: Methods for calibrating a display device, for instance, a computer monitor, that transduces digital inputs to regions of perceived color. The brightness control is calibrated by (1) supplying to the display device digital inputs that produce a black area and an adjacent dark gray area; (2) adjusting the brightness control of the display so that the black area and the gray area are distinguishable; and (3) slowly reducing the brightness control to the point that the black area and the gray area are indistinguishable.
