Abstract
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′ value of the predetermined reference image.
