Abstract

The present invention provides an optical anti-shake method and device for an imaging device, the method comprising: obtaining the image shaking trend of the output image frame of the imaging device; according to the anti-shaking parameters preset by the imaging device, the focal length magnification value and The anti-shake gain value is obtained through the calculation of the image shake trend; the movement data of the anti-shake lens of the imaging device is adjusted according to the anti-shake gain value to reduce the image shake amplitude. In the present invention, the shake degree of the output image is fed back to the optical anti-shake system, combined with the feedback information, the movement data of the anti-shake lens is automatically adjusted to minimize the image shake amplitude, thereby realizing the integration of the image and the optical anti-shake system Closed-loop control ensures the transient and steady-state anti-shake performance of the anti-shake equipment.

Description

technical field [0001] The invention relates to the field of optical anti-shake, in particular to an optical anti-shake method and device for an imaging device. Background technique [0002] During the shooting process of the surveillance camera, it may be shaken due to the influence of its environment, and at this time, the image captured by the surveillance camera will become blurred. In order to ensure that the image is clear during camera shooting, it is necessary to introduce camera anti-shake related technologies. [0003] At present, the commonly used anti-shake technology is optical anti-shake: the small movement of the camera is detected by the gyroscope inside the lens, and the signal is sent to the microprocessor to immediately calculate the amount of displacement that needs to be compensated, and then through the compensation lens group, according to The shake direction and displacement of the lens are compensated, so as to effectively overcome the image blur ca...
