Method for shooting light painting video and mobile terminal

Abstract

The invention discloses a method for shooting a light painting video. The method includes the following steps of unceasingly collecting light painting images through a camera after shooting starts, intermittently reading the light painting images, generating a synthesized image according to the current light painting image and the collected light painting images, grabbing the synthesized image, conducting video coding on the grabbed synthesized image, and generating the light painting video according to the synthesized image processed through video coding. The invention further discloses a mobile terminal. By means of the method and the mobile terminal, the video displaying the running process of a light source can be shot through a shooting device; or the method and the mobile terminal can be applied to similar application scenes; the requirements of users for diversification are met; user experience is improved. Meanwhile, due to the fact that the synthesized image is coded while shooting is conducted, the generated synthesized image does not need to be stored; thus, the size of a video file obtained through shooting can not be too large, and storage space can not be occupied too much.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to a method for shooting light painting videos and a mobile terminal. Background technique [0002] With the continuous improvement of camera hardware of mobile terminals such as mobile phones and tablet computers, the shooting functions of mobile terminals are becoming more and more diversified, and users have higher and higher requirements for shooting of mobile terminals. The shooting functions of current mobile terminals depend on the relevant processing algorithms provided by camera hardware equipment and chip suppliers, and only have several fixed shooting modes such as focus and white balance. In recent years, a shooting mode of light painting photography has emerged, and users can use light painting photography for artistic creation. Light painting photography refers to a shooting mode that uses long-time exposure to create special images through changes in the light source...

AI Technical Summary

Problems solved by technology

Due to the need for long-time exposure, corresponding light-sensitive hardware is required to support it, and the light-sensitive hardware that can support long-time exposure is relatively expensive, so currently only professional camera devices such as SLR cameras have light painting photography functions

[0003] The current light-slow photography can only take light-painted photos, that is, the final result is only a static image showing the trajectory of the light source, and it is impossible to shoot a dynamic video that can show the operating process of the light source

Therefore, there is no solution for shooting light painting video in the prior art, which cannot meet the diverse needs of users and affects the user experience
