Method and device for taking pictures with dual cameras

Abstract

A dual-camera photographing method, which is applied to electronic equipment, the method includes: acquiring a shooting target; when it is determined that the current light is dark, adopting a first focusing method to focus on a first camera and a second camera, and determining the The first focus position of the first camera and the second focus position of the second camera; based on the first focus position and the second focus position, shoot the shooting target; when it is determined that the current light is not dark When using the second focusing method to focus the first camera and the second camera, determine the third focus position of the first camera and the fourth focus position of the second camera; based on the first The third focus position and the fourth focus position are used to shoot the shooting target. The invention also provides a dual-camera photographing device. The invention can automatically select the focus corresponding to the light according to the light in the photographing environment, thereby improving the focus speed and accuracy.

Description

technical field [0001] The present invention relates to the technical field of photographing, and in particular to a dual camera photographing method and device. Background technique [0002] In order to improve the photographing effect of terminals, more and more electronic devices use dual cameras, one color camera and one black and white camera. However, the use of dual cameras requires focusing on the two cameras so that the two cameras can be in focus. If the focus is not successful, the object to be photographed will not be able to be clearly imaged. The current focusing method cannot automatically select the focusing method corresponding to the light according to the light in the photographing environment. In this way, since the color sensor of a color camera does not receive as much light as the black and white sensor of a black and white camera in a low light environment, the problem of inaccurate focusing and slow focusing speed is likely to occur in a low light ...

AI Technical Summary

Problems solved by technology

If the focus is not successful, the object being photographed will not be able to be clearly imaged

The current focusing method cannot automatically select the focusing method corresponding to the light according to the light of the photographing environment

In this way, because the color sensor of the color camera does not receive as much light as the black and white sensor of the black and white camera in low light environments, it is easy to have inaccurate and slow focusing problems in low light environments.
