发明名称 Color calibration of display devices
摘要 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. Also, the digital-input-to-perceived-color transducing of the display device is calibrated by: (1) supplying digital inputs to produce a white area and one or more color patch areas each having a perceived color other than white; (2) overlaying on the white area one or more filter chips that each produce a desired reference color; and (3) conforming the perceived color of each color patch and the perceived color produced by the corresponding filter chip by adjusting the digital input for the color patch or the filter value of the filter chip.
