In a conventional single-exposure photograph, moving objects or moving cameras cause motion blur. The exposure time defines a temporal box filter that smears the moving object across the image by convolution. This box filter destroys important high-frequency spatial details so that deblurring via

causes a variation in exposure time across the detector of no more than 0.0009 seconds. On-orbit ratios of actual versus commanded exposure times are also the same as in ground tests. The shutter fails to meet the repeatability requirement of 0.01 seconds, as expected from ground testing results (Hilbert

The majority of consumer quality cameras sold today have CMOS sensors with rolling shutters. In a rolling-shutter camera, images are read out row by row, and thus each row is exposed during a different time interval. A rolling-shutter exposure causes geometric image distortions when either

velocity model for camera motion and estimates these additional parameters in a bundle adjustment. In experiments on synthetic and real image sequences we demonstrate how effects caused by a rolling shutter video camera can be compensated by the velocity estimation.

Abstract- We propose an approach for keeping the light shift in laser cooled frequency standards down to the lo-’ ’ level without the use of mechanical shutters. For laser systems using a master-slave laser configuration, cutting the injection power to a slave causes it to lase at its free

Abstract — We present measurements confirming operation of a cesium fountain frequency standard with light shift below 10-15 (and with evidence suggesting it is several orders of magnitude below this level) but without the use of mechanical shutters. Suppression of the light shift is realized using

for robust tracking; images are often received at less than 15Hz; long exposure times result in significant motion blur; and finally, a rolling shutter causes severe smearing effects. This paper describes an attempt to implement a keyframe-based SLAM system on a camera phone (specifically, the Apple iPhone 3

There is a trend toward improving the quality of hazard-warning decisions in order to reduce danger and interruption of work or leisure caused by electrified clouds and thunderstorms. Lightning warning devices
