Rolling Shutter with Global Reset
For each frame in cameras with a rolling shutter with global reset, the lines have the exposure start time while
the stop time for exposure is delayed by the offset of the previous line’s readout. For each line the exposure
time gradually lengthens and data readout begins immediately following the line’s exposure. While the readout
time for each line is the same, the start and stop times are staggered.
The reduction in image artifacts such as skew and wobble that can be typical of rolling shutters is an advantage
of the global reset feature. However, due to increased exposure length throughout each frame there may be an
increase in brightness moving from top to bottom on an image.
