Patent ID: 7121944

Claim:
A device comprising: a light sensor for detecting ambient light around a money-operated gaming machine and generating a first signal corresponding to the ambient light, the gaming machine comprising an illuminated display for displaying a game of chance and one or more selectively illuminated features, the one or more selectively illuminated features being illuminated based an a status of a game being played; a circuit connected to receive the first signal, the circuit outputting a control signal based on the first signal; a power supply connected to receive the control signal for controlling an output of the power supply; and at least one light within a gaming machine receiving power from the power supply, the at least one light illuminating the display of the game of chance and the one or more selectively illuminated features, a brightness of the at least one light being controlled such that an increased ambient brightness increases the brightness of the at least one light, and a decreased ambient brightness decreases the brightness of the at least one light, wherein the light sensor comprises an integrator for preventing transient changes in ambient light from substantially affecting the brightness of the lights.
