Global Shutter

  • all pixels in a frame are exposed to light at the same time

  • mostly supported by CCD image sensor (one read per frame)

Rolling Shutter

  • pixels are read and stored line-by-line in a frame

  • mostly happens as the side effect of CMOS sensors

Example image in the presence of rolling shutter effect.

Example video in the presence of rolling shutter effect (also called "jelly" effect).

Three factors contributing to this jelly effect:

  • The camera is a rolling shutter camera

  • The camera is rigidly attached to a quadrotor (without gimbal)

  • The quadrotor frame by itself has high frequency vibration (without damping design)
