Abstract:
1. A method of calibrating a display, comprising: setting an illumination level of a first illumination lamp to its minimum illumination level and recording a first minimum input signal from a power source to the first illumination lamp; setting an illumination level of a second illumination lamp to its minimum illumination level and recording a second minimum input signal from the power source to the second illumination lamp; increasing the illumination level of the first illumination lamp to its maximum illumination level and recording a first maximum input signal from the power source to the first illumination lamp; increasing the illumination level of the second illumination lamp to its maximum illumination level and recording a second maximum input signal from the power source to the second illumination lamp; determining the difference between the first and second minimum input signals; determining the difference between the first and second maximum input signals; and using the differences in the minimum and maximum input signals to map the illumination levels of the first and second illumination lamps as functions of the input signals.
