Digital camera anti-shake technology belongs to what patent classification?

IS optical image stabilization IS a kind of image stabilization technology, that is, lens image stabilizer, which is based on the sensor in the lens to sense the horizontal and vertical displacement and make corresponding compensation. IS is Canon's technology, which is Canon's name for optical image stabilization. Other companies, such as Kodak, also call it that. Most of them use the same anti-shake principle, but the names are different, but they should all be a kind of lens defense, but the names are different.

The real inventor of Sony AS fuselage anti-shake technology is Konica Minolta, which began to develop a unique CCD shift anti-shake technology from 200 1. It does not put the anti-shake device in the lens, but is designed on the CCD.

Body anti-shake and lens anti-shake mean that the anti-shake system is located in different positions. Anti-shake of fuselage was first created after the appearance of digital camera. The anti-shake system is located on the CCD photosensitive system. The principle of CCD anti-shake is to put the CCD on a bracket that can move up and down, left and right, and first detect whether there is jitter. Because of the gyro sensor, the jitter detection is basically the same as that of other companies. Then, the sensor detects the direction, speed and movement amount of the jitter ... The detected signal is processed to calculate the CCD movement amount sufficient to offset the jitter. Prior to this, anti-shake can only be attached to the lens, and veterans in the field of professional cameras such as Canon and Nikon are among them.
