Embodiment 1

[0022] Embodiment 1 of the present invention provides a shooting method based on dual cameras. The method can be executed by a dual-camera shooting device, wherein the device can be implemented by software and / or hardware, and generally can be integrated in a mobile terminal. figure 1 It is a schematic flowchart of the dual-camera-based shooting method provided in Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes:

[0023] S101. Obtain light intensity information of an external environment, and determine a main camera and an auxiliary camera.

[0024] Specifically, the light intensity information of the external environment may be acquired only when the shooting program or software corresponding to the dual cameras is started, or the light intensity information of the external environment may be acquired in real time or at preset intervals after the camera function of the device is turned on. The method of obtaining the light intensity...

Embodiment 2

[0038] figure 2 It is a schematic flowchart of a shooting method based on dual cameras provided in Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments. Further, before obtaining the light intensity information of the external environment and determining the main camera and the auxiliary camera, it also includes: obtaining the camera switching mode of the device; if the camera switching mode If it is an automatic switching mode, the main camera and the auxiliary camera are determined according to the distance information between the current device and the scene to be photographed; if the camera switching mode is a manual switching mode, the main camera and the auxiliary camera are determined according to the user's switching operation.

[0039] Correspondingly, such as figure 2 As shown, the shooting method based on dual cameras provided in this embodiment includes:

[0040] S201. Obtain the camera switching mode of the ...

Abstract

The embodiment of the invention discloses a camera shooting method and device based on double cameras. The method comprises the steps of acquiring light intensity information of an external environment, and determining a main camera and an auxiliary camera; if the light intensity information is lower than a light intensity threshold value corresponding to the main camera, collecting light of the current external environment through the auxiliary camera, and supplementing into an imaging picture of the main camera, so that the light intensity when the main camera is used for camera shooting is increased; starting the main camera to shoot a scenery to be shot. According to the embodiment of the invention, by adopting the technical scheme, when the light intensity is weaker, light is supplemented for the imaging picture of the main camera through the auxiliary camera, so that the light intensity and the light supplementing effect of the imaging picture of the main camera can be improved, the imaging effect of the scenery shot by the main camera is improved, the calculated amount required in a shooting process is reduced, the requirement on the performance of a central processing unit is reduced, the cost of terminal equipment is reduced, and the utilization ratio of the double cameras is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photographing, and in particular, to a method and device for photographing based on dual cameras. Background technique [0002] In recent years, with the development of photographing technology and the improvement of people's requirements for photographing quality, more and more developers have begun to equip their mobile terminals with rear dual cameras to improve the photographing quality of users. [0003] Dual cameras in mobile terminals usually include a wide-angle camera and a telephoto camera, wherein the wide-angle camera is a wide-angle camera device that can accommodate more scenes within a limited distance; the telephoto camera is a long-focus camera The photographing equipment generally can be used to photograph the scenery that is far away from the mobile terminal. The existing dual cameras equipped in the mobile terminal are usually used to shoot the scenery at the sam...
