Abstract

The invention provides an optical anti-shake method and an optical anti-shake device for camera equipment. The method comprises the following steps: acquiring an image shake trend of an image frame output by the camera equipment; carrying out calculation to obtain an anti-shake gain value according to an anti-shake parameter preset by the camera equipment, a focal length multiplying power value and the image shake trend; and adjusting movement data of an anti-shake lens of the camera equipment according to the anti-shake gain value so as to reduce the image shake amplitude. According to the invention, the shaking degree of the output image is fed back to the optical anti-shake system, and movement data of the anti-shake lens is automatically adjusted in combination with the feedback information, so that the shake amplitude of the image is minimized, the closed-loop control of the image and the optical anti-shake system is realized, and transient and steady anti-shake performance of theanti-shake equipment is ensured.

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...
