Colored frames from DLP projection while changing camera aperture
I am working on a project which involves using a projector-camera system. I am using a DLP projector & Canon PowerShot G7. While changing aperture i am observing sequence of Red,Green,Blue frames. Since G7 has global shutter, i expected it to happen while changing the shutter speed due to mismatch in frequency of color wheel in projector & shutter speed. But i am surprised to see it happens while changing the aperture also.
Would anybody please enlighten me on this issue?
