Image Sensors and Shutter-related Artifacts Andrey Filippov Elphel, Inc. 1405 W. 2200 S. #205 West Valley City, UT 84119 Image sensors and shutter-related artifacts

Frame transfer CCD image sensor Image sensors and shutter-related artifacts

Interline transfer CCD image sensor Image sensors and shutter-related artifacts

Image sensors and shutter-related artifacts “Smear” artifacts of the interline transfer CCD image sensor (KODAK KAI-11002) 1 - smear during fast pre- exposure vertical pixels shift (clearing CCD) 2 - smear during slower vertical shift (readout) 3 – vertical smear from the stationary objects (dark pole above) Image sensors and shutter-related artifacts

Image sensors and shutter-related artifacts “Smear” and blooming artifacts in the interline transfer CCD image sensor Image sensors and shutter-related artifacts

CMOS image sensor with the electronic rolling shutter (ERS) Image sensors and shutter-related artifacts

Image sensors and shutter-related artifacts ERS distortions of the moving objects, horizontal sensor scan lines (landscape mode) Image sensors and shutter-related artifacts

Image sensors and shutter-related artifacts ERS distortions of the moving objects, vertical sensor scan lines (portrait mode) Image sensors and shutter-related artifacts
