Rolling Shutter
For each frame in cameras with a rolling shutter sensor the exposure for each line begins at an offset equal the
readout time for each line. While the exposure time for each line is the same, the start and stop times are
staggered. Each line’s data readout begins immediately following the exposure. Readout time for each line has
the same length but staggered start and stop times.
Increase sensitivity is one of the advantages of rolling shutter, however due to the varying start times
throughout the frame, there are known artifacts such as skew, wobble and partial exposure. Please see
rolling for additional information.
