Now is clearly obvious why MOS sensors have mechanical shutters like the E-P1 and so on. @Edvian: thanks for the explanation about CCD sensors, that is what I thought.

CMOS sensors have no such possibility, so light must be cut off mechanically at the end of exposure. The charges are then read out slowly for A/D conversion. Video recording with CMOS sensors use a "rolling shutter" where row by row of pixels are cleared, then read out later. The top of the picture is captured 1/30 second after the bottom, making "jello" effects possible if you move the camera fast in the mean time. Re mechanical shutter:
