Rotation compensation device

Abstract

The invention relates to a rotation compensation device, which comprises a base, a carrier and a base plate, wherein at least one multi-axis rotating bracket surrounds the periphery of the carrier, apair of rotating elements is respectively fixed between the multi-axis rotating bracket closest to the carrier and the carrier, between two adjacent multi-axis rotating brackets, and between the baseand the adjacent multi-axis rotating bracket, the rotating element is provided with an inner side connecting part, an outer side connecting part and a rotating shaft homodromous connecting body connected between the inner side connecting part and the outer side connecting part, a driving module enabling the carrier to rotate along the rotating shafts of one pair of the rotating elements in the same direction is arranged between the carrier and the base, a control module connected with the driving module and a light path adjusting element is arranged on the base plate, and the control module isfurther connected with a position sensor used for judging the rotating angle of the carrier. According to the invention, the compensation rotation dimension is increased, and the rotation of each shaft is independent from each other and is not influenced by a linkage mechanism, so that the shockproof compensation device with a simple structure and capable of making the image center to the edge clear is formed.

Description

technical field [0001] The invention relates to a rotation compensating device, which is suitable as a compensating device for unstable images caused by external vibrations in an optical system. Background technique [0002] Generally, the optical systems of common handheld optical products on the market, such as digital cameras, camcorders, and mobile phones, are composed of optical lens groups and image sensors. During the shooting process, it is easy to be shaken by external forces, such as hand-held, vehicle movement, and external environmental factors, which cause the device to shake, which in turn leads to problems such as inability to clearly image or blur images. The image compensation system commonly used in mobile phones on the market uses lens shifting to compensate for light path deviation. However, this compensation mechanism usually results in a clear center but blurred or shaken corners in image recognition. This phenomenon is mainly caused by the non-synchro...

Problems solved by technology

The translation compensation mechanism is not obvious to the naked eye when it is shaken at a small and slow speed, but it is easy to cause image incongruity when it is in a dark environment, large angle and fast shaking, and there is room for improvement.
