ABSTRACT:
A system for correcting an output device for the effects of reflected ambient illumination comprises a reflection device of known reflectivity. The color display memory stores a first graphical interface and a second graphical interface. The first graphical interface displays a range of intensities of outputs that the display device can generate. The second graphical interface displays a range of hues that the display device can generate. The reflection device has a target surface which defines an aperture. The ambient light reflecting from the target surface is compared to the first graphical interface and to the second graphical interface by viewing the interfaces through the aperture. The system receives a first input of an intensity of the first graphical interface that appears to match the ambient illumination reflected from the reflection device; the system then receives a second input of a hue of the second graphical interface that appears to match the ambient illumination reflected from the reflection device. The system determines the intensity and hue of the ambient illumination reflected from the output device by matching the intensity and hue of the ambient illumination reflected from the reflection device with the output of the output device. The system then adjusts the outputs of the output device to compensate for the reflected ambient illumination.
