After selecting a micro pixel under a microlens, do we scale it up the light received by that pixel by the average amount of light coming through the entire microlens?

@lucida. The point here is to simulate a photograph that would be taken by a [near]-pinhole camera posited at a point on the main lens. Your suggestion is to scale the exposure of this camera by the average amount of light hitting over the entire main lens. But you don't want to do that because our virtual pinhole camera wouldn't be affected by light hitting elsewhere on the main lens!
Scaling the pixel's value up or down would be equivalent to changing the exposure time of the virtual pinhole camera.
