2.2 Rolling and Global Shutter
ThesCMOSsensorusedbytheZyla5.5oersachoiceofbothRollingandGlobalshutter,providingsuperior
applicationexibility.RollingandGlobalshuttermodesdescribetwodistinctsequencesthroughwhichthe
imagemaybereadoasCMOSsensor.Inrollingshutter,chargeistransferredfromeachrowinsequence
duringreadout,whereasinglobalshuttermodeeachpixelinthesensoreectivelyendstheexposure
simultaneously. However, lowest noise and fastest frame rates are achieved from rolling shutter mode.
Traditionally,mostCMOSsensorsoereitheroneortheother,butveryrarelydoestheuserhavethechoice
of both from the same sensor. For the Zyla 5.5, it is possible to select between either readout mode from the
samesensor,sothemostappropriatemodecanbeselectedforthespecicapplication.TheZyla4.2oers
Rolling Shutter only.
