yes I forgot about electronic shutters: essentially a non-mechanical version of a scanner where each row is "exposed" in sequence.
So I stand corrected: even though your phone is using a "single"-shot cmos/ccd sensor, as there is no mechanical shutter they thus capture the data one line at a time in a way that is analogous to a scanner.
Way cool effect! (too bad you can't get your Canon 5d to simulate it!)

M, OK ... so if the camera in the phone is not performing a scanning process during "image acquisition" (or maybe during postprocessing) then what causes the artifact that looks like it was caused by some scanning artifact? ?? andy editor@xxxxxxxxxxxxxx wrote: > well, of course, your digital camera is not a scanner (they are all single-shot these days) and thus would not render such an interesting result! > > M
