Thanks Ajay, but I still don\'t see how a global left/right asymmetry could arise. The angle hitting a microlens/photosite/pixel on the extreme left side will be exactly the same as one symmetrically on the extreme right side. So why is there a red hue on the left side and cyan hue on the right side?


I guess the color shift is asymmetric because the angle of incidence onto the RGBG quadruplets of the Bayer array is different in each quadrant of the sensor. Some of the subpixels will be attenuated more and some will be excited more due to the light leakage caused by the obliquely incident light. The RGBG subpixel arrangement is the same all over the sensor, but depending on the direction the light is coming from, the light leakage must affect different subpixels. Makes sense?
