ABSTRACT:
Method and apparatus for compensating for variations in the output signal of a color sensor due to varying temperature of the color sensor. The color sensor receives light and generates an output signal that is based on the received light. The temperature compensation mechanism measures the temperature of the color sensor and uses the measured temperature to selectively adjust the output signal of the color sensor to generate a compensated output signal that is not dependent on temperature of the color sensor.
