Problems solved by technology
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.

The invention discloses a dual camera shooting method, applied to electronic equipment. The method comprises the following steps: obtaining a shooting target; controlling a first camera and a second camera to simultaneously carry out focusing, and determining an initial focus position of the first camera and a second focus position of the second camera; when the initial focus position is within an adjacent range of the second focus position, determining a first focus position based on the initial focus position; when the initial focus position is not within the adjacent range of the second focus position, driving a first focus lens of the first camera to move from the initial focus position to a reference position in the adjacent range, and determining the first focus position based on the reference position; and shooting the shooting target based on the first focus position and the second focus position. The invention also provides a dual camera shooting device. According to the dual camera shooting method and device disclosed by the invention, the focus speed and accuracy in dark environments can be improved.
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 is generally that the color camera focuses first, and the black-and-white camera focuses according to the focal position of the color camera. 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 ...
