Abstract

The embodiment of the invention discloses a photographing method that includes steps of: acquiring the shake speed of a current frame by using the speed information of a previous frame of image duringa photographing shake; acquiring the shake displacement threshold of the current frame by using the imaging parameter information of the current frame, wherein the imaging parameter information includes the pixel width, the object distance and the image distance of an imaging sensor; and calculating the exposure time threshold of the current frame according to the shake speed of the current frame and the shake displacement threshold of the current frame; and adjusting the actual exposure time of the current frame according to the exposure time threshold of the current frame. The embodiment of the present invention also discloses a photographing terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a photographing method and a terminal. Background technique [0002] With the popularization of mobile terminals such as smart phones and tablet computers, their built-in camera functions have a very high usage rate in daily social life. When using a mobile terminal to take pictures, it usually encounters overexposure or underexposure, and the obtained image is too bright or too dark. In addition, shaking hands when taking pictures is easy to take blurred images. Therefore, it is an urgent problem to be solved to obtain high-quality images within the allowable range of shaking by automatically adjusting the exposure time. [0003] In the prior art, according to the light intensity value of the current environment, the exposure time required for shooting is obtained, and then the target displacement value of the terminal movement is obtained. If the target displa...
