It seems to me that the autofocus function of the projector does a descent but not perfect job. Perhaps it could be improved? I have tried to understand how it works currently, and this is my assumption: The projector tries a number of different focus settings, and at each setting, it measure the contrast of the test-pattern. Higher contrast equals better focus. But it does this in discrete steps, not continually. Would it be possible to continue doing what it is already doing, but then to try smaller steps just around that setting (in a second phase) to get the focus just right (so that we don’t have to do the manual adjustment to get it just right)?
