Saturation

Color images can be converted to grayscales by setting the Red, Green and Blue values of each pixel to the same value, using the following algorithms:

Simple Averaging Grayscale.
gray = (red + green + blue) / 3

Weighted Averaging Grayscale
gray = ( (3 * red) + (4 * green) + (2 * blue) ) / 9

NTSC-PAL Grayscale.
gray = (0.299 * red) + (0.587 * green) + (0.114 * blue)

If you would like to see support for other grayscles built into CalibrationAider, please email software@imagingassociates.com.au. Thanks!
