Image-stabilized binoculars are binoculars that have mechanisms to reduce the apparent movement of the display due to binoculars. Binocular stable images are designed to minimize image shake in handheld binoculars. Higher power binoculars carry the picture closer, but the image shift is also larger with smaller hand movements. Image stabilization technology in binoculars ensures instant image adjustment to compensate for movement. The main brands that make images of stabilized binoculars include Canon, Fujinon, Nikon, Carl Zeiss, and Bushnell.
Several different mechanisms have been used for image stabilization.

Sistem aktif
In this system changes in binoculars are perceived electronically, and some parts of the system are altered to correct this offset. The lens group can be shifted, or the fluid-filled prism angle can be changed.

Passive system
In this system there is no feedback from the sensor to the corrective element. All binoculars can be stabilized by using a gyroscope, or prism binoculars can be detached from the house, allowing them to not be affected by binoculars movement.
Use
Stable binocular images are often used when viewing from moving objects such as boats or planes. They are also very helpful with high powered binoculars. Stable binocular images have become popular among amateur astronomers.
Other image stabilizer options
Image stabilization is also used in video and camera lenses.
