Method and apparatus for automated optimization of white and color balance on video camera

摘要

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.
