Self-shooting method and self-shooting device for mobile terminals

Abstract

The invention relates to the electronic field, and discloses a self-shooting method and a self-shooting device for mobile terminals. The method includes the following steps: periodically acquiring the current frame of view finding of a camera; automatically correcting the distortion of the current frame in real time, and displaying the frame after correction on the screen of a mobile terminal in real time; controlling the camera to carry out shooting formally after receiving a shooting instruction; and correcting the distortion of a formally shot target image automatically and storing the target image. According to the invention, during view finding of shooting, real-time automatic correction of frame distortion on the screen of the mobile terminal can be realized, and distortion correction can be carried out automatically on the shot target image so as to obtain an image in line with human visual habits.

Description

technical field [0001] The invention relates to the electronic field, in particular to a Selfie technology of a mobile terminal. Background technique [0002] In recent years, portable mobile terminals have become popular all over the world. With the development of science and technology, their computing processing and network connection functions have become more and more powerful, and their costs have become lower and lower, providing new ways for people to obtain information, communicate, work and entertain. [0003] In particular, many people now like to take selfies with mobile terminals such as smart phones (that is, use mobile terminals to take pictures of themselves). However, due to the limitation of the length of the human arm on the view point of the shooting, the selfie photo has the following limitations: First, the selfie is limited in viewfinder. Generally, the selfie can only capture the head and shoulders of the person, covering the upper body at most; If yo...

Problems solved by technology

However, due to the limitation of the length of the human arm on the view point of the shooting, the selfie photo has the following limitations: First, the selfie is limited in viewfinder. Generally, the selfie can only capture the head and shoulders of the person, covering the upper body at most; If you take pictures of the lower body of your body, due to the significant difference in the distance between each part of the human body and the lens, the captured image will appear to have extremely short legs and small feet, which will greatly affect the effect of Selfie photos; Selfie, although to a certain extent, can alleviate the limitation of viewfinder range, but it will bring more image distortion

[0005] Secondly, if you need to shoot a part far away from the lens (lower body), the lens often has to be tilted relative to the subject, which will cause perspective distortion, making the part of the subject farther away from the lens appear too small in the image (with the lens and subject at normal visual distance)
