Problems solved by technology

Moreover, whether it is optical anti-shake or electronic anti-shake, a motion sensor is generally required to perceive the direction and intensity of motion, and then optical and electronic methods are used to compensate, which increases the limitations of terminal equipment to achieve anti-shake technology

Abstract

The embodiment of the invention discloses a video anti-shaking method and terminal equipment, which are applied in the technical field of mobile communication. The method comprises the following steps: starting a video recording function, acquiring a first video frame image, determining a first coordinate of a target shooting object in a first video frame image, and taking the first coordinate as a reference coordinate; acquiring a second video frame image, and determining a second coordinate of the target shooting object in the second video frame image; and calculating an offset vector of the second coordinate relative to the reference coordinate, cutting the second video frame image according to the offset vector to obtain a target video frame image if the offset vector exceeds a preset threshold value, and outputting the target video frame image. Through adoption of video anti-shaking method and terminal equipment, video anti-shaking can be realized without support of hardware, and limitation on realization of an anti-shaking technology by the terminal equipment is lowered.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a video anti-shake method and terminal equipment. Background technique [0002] With the development of electronic technology, it becomes easier to obtain video with mobile phones, digital cameras, digital video cameras and other devices. However, in the absence of professional equipment (such as a camera stand, etc.), these hand-held devices inevitably cause image shaking due to natural shaking of human hands or interference from external natural factors. This vibration avoidance can be achieved through anti-shake technology. [0003] The current video anti-shake technology is mainly divided into two categories: optical anti-shake and electronic anti-shake. Optical image stabilization is to use the gyro sensor in the lens to detect the movement generated when shooting video, then process the detected movement information, and calculate the compensation mov...
