摘要：
An apparatus to automatically adjust, in accordance with a set of user preferences, a computer display parameter, such as brightness or contrast, in response to ambient light conditions is described. The apparatus includes an ambient light sensor to obtain an ambient light signal. A mapping mechanism, connected to the ambient light sensor, maps the ambient light signal to a user preference value in a user preference table. Computer display control circuitry, connected to the mapping mechanism, then adjusts the selected computer display parameter of the computer display in response to the user preference value. A preferable embodiment of the invention includes colored light sensors that produce colored ambient light signals. The colored ambient light signals are mapped into colored preference tables. By adjusting the values in the colored preference tables, the image appearing on the computer display can be matched to a replica of the image printed on paper.
