FUJINON’s Optical Image Stabilization

The video below shows the effect of the Optical Image Stabilization (OIS) in the FUJINON D60x16.7 zoom lens.

The company says that designers of demanding surveillance systems, where cameras and lenses might possibly be exposed to vibrations, should get it right from the beginning and compare the capabilities of optical versus electronic image stabilization by, for example, evaluating its D60x16.7 zoom lens with 60x zoom, 2 megapixel resolution for up to 1/1.8” image sensors.

It goes onto say that even Even small vibrations of the mounting point of zoom lenses can lead to very shaky and often unusable video captures. To be on the save side, high-performance image stabilization is key to compensate such vibrations.

The vibrations which influence a camera and zoom-lens installation may derive from heavy engines in a building, ship, or other vehicles. They can also be induced by bypassing railway trains or strong, low-frequency sound sources in factory environments, or even just strong winds.

The company argues that whereas software based stabilization might sound like a good hands-on solution, Optical Image Stabilization from FUJINON has multiple advantages over electronic/software based approaches which includes

  1. Higher picture quality without frame loss
    This is especially true at the observation of moving objects. While software based stabilization requires several frames to calculate a stabilized image, optical stabilization provides instant results without losing any frames.
  2. Maximum field of view and constant image section
    Electronic stabilizers require cropping numerous pixels at the edges of the video image while optical stabilization continuously shows the full frame without losing image sensor resolution or field of view.
  3. Compensation of up to 4x stronger vibration
    The Optical Image Stabilization in FUJINON’s zoom devices is capable to deliver steady video captures even at vibrations which are up to four times stronger than software based stabilizers can compensate, depending on frequency and amplitude of the vibration.
