An image of an optical target including dark and light monochromatic patches is captured. An average YUV value is calculated from a predetermined number of YUV values for each monochromatic patch. A white balance is performed using the averaged YUV values and a predetermined reference image. Each averaged YUV value is converted to an equivalent RGB value. A difference in RGB values between the light and the dark monochromatic patches produces a dynamic range for the RGB values. The dynamic range for the G value is adjusted to match the dynamic range for a G&prime; value of the predetermined reference image.

A programmable digital filter. The digital filter detects a predefined pattern over a programmably variable duration. The filter includes an interval register which is coupled to receive an interval count. A sample register is coupled to receive a plurality of samples of an input signal which is sampled at an interval determined by the interval count. A plurality of pattern matching circuits generate a pattern match output if the plurality of samples matches one of a plurality of predetermined patterns, and a state logic circuit generates a signal if a new match is found. The pattern matching circuits may be stable high and stable low test circuits which cooperate to determine if all of the plurality of samples are of a consistent logic value.
