Problems solved by technology

However, when the user uses the terminal to take pictures, it usually causes shaking due to various reasons, such as pressing the camera button, the user is moving, etc., resulting in blurred pictures and poor quality
At present, the commonly used anti-shake technology is algorithm anti-shake. The dynamic vector between two adjacent image frames in the shooting process is calculated by software, and then the current image is moved in reverse, that is, the image after anti-shake is obtained. The algorithm anti-shake moves in reverse The current image, image processing may cause image distortion, poor anti-shake effect

Abstract

The embodiment of the invention discloses an anti-shake photographing method and device. The method includes the steps that cache image frames are obtained through a terminal camera, and the obtained cache image frames are stored in an image cache queue; a photographing instruction is received; the image definition values of the cache image frames in the current image cache queue are obtained; the cache image frame with the highest image definition value is determined as the photographed image, and the photographed image is output. By means of the photographing method and device, the anti-shake effect of terminal photographing can be improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an anti-shake photographing method and device. Background technique [0002] With the development of terminal technology, the camera has become the standard configuration of most terminal equipment, providing users with the function of taking pictures, bringing great fun and convenience to people's life and work, and the camera pixels are getting higher and higher, aiming to allow users Take better quality photos. However, when the user uses the terminal to take pictures, it usually causes shaking due to various reasons, such as pressing a camera button, the user is moving, etc., which in turn causes blurred pictures and poor quality. At present, the commonly used anti-shake technology is algorithm anti-shake. The dynamic vector between two adjacent image frames in the shooting process is calculated by software, and then the current image is moved in reverse, that is, ...
