Only use Camera to Calibrate the color ? brightness? between more two cameras? #18
Description
- I have some questions about how to calibrate the color with the camera.
As we know the camera didn't support measuring the luminance or gamma of projection color. Thus, we can not really know where is the position of SRGB's xyY value. How you can calibrate the color between two projectors if you don't have the correct brightness of those projectors?
Linear R value X
Linear G value = |M| Y
Linear B value Z
x = X/ (X+Y+Z)
y = Z/ (X+Y+Z)
Y=Y #"LUMINANCE"
