Basic of electronic shutter
(combination of shutter and reset)
1. Global shutter + global reset

Complete global shutter action

As scanning time is longer in lower part of image, black floating phenomenon
might be caused by dark current effect. ＝ This can be corrected as it is slight
2. Global shutter + rolling reset

Global shutter mode can reduce an effect of time difference during reading by
resetting on each line

In some cases, effect of virtual global reset is achieved by high speed rolling
reset
3. Rolling shutter + global reset

As only resetting is done in one time, exposure time after reset varies on each
line.
＝ The lower part of image is the brighter as exposure time is longer.
4. Rolling shutter + rolling reset

Complete Rolling shutter action

Stable exposure process as both reset and shutter are rolling mode

Easier to make low noise type sensor as structure of less pixel transistor number.

As disadvantage, motion image shot under continuous light will be distortive.
