Photographic anti-shake

The concept of anti-shake was first put forward by Nikon Corporation of Japan in 1994. 1995, Canon introduced the first lens EOS75~300MM F4~5.6IS with image stabilizer.

The full name of IS is IMAGESTABILIZER, which is also our daily oral anti-shake.

Anti-shake can be divided into three types:

Optical anti-shake, electronic anti-shake, photoreceptor anti-shake.

There are two kinds of optical image stabilization: lens image stabilization and imaging device image stabilization. Lens anti-shake is to set a special anti-shake compensation lens group in the lens, adjust the position and angle according to the camera's shake direction and degree, and keep the optical path stable.

Among them, the brands with advanced technology and strong anti-shake performance are Canon's IS series lens, Nikon's VR series lens and Sony's OSS lens.

Electronic anti-shake mainly refers to the anti-shake of digital camera by forcibly increasing the photosensitive parameters of CCD, speeding up the shutter speed, analyzing the images obtained on CCD, and then using edge images to compensate. In fact, it is an anti-shake technology that reduces the image quality, which is cheaper than optical anti-shake.

Anti-shake of fuselage is to design a vibration sensor inside the fuselage. This technology can analyze the amplitude of hand jitter and move the photosensitive element in the opposite direction to offset the influence of hand jitter and obtain a clear image.
