Embodiment 1

[0024] refer to figure 1 , showing a flow chart of the steps of an embodiment of a method for setting shooting parameters of the present invention, which is applied to a mobile terminal with at least two cameras, the cameras include a main camera and a secondary camera, and the main camera is set according to the first A preset frame rate to output image data, the secondary camera is set to output image data according to a second preset frame rate, the method may specifically include the following steps:

[0025] Step 101, acquiring second image data output by the secondary camera according to a second preset frame rate;

[0026] In a specific implementation, there are at least two cameras on the mobile terminal, and of course there may be three or more cameras. In the embodiment of the present invention, the camera can be used to collect images, and different cameras can be set with different frame rates to output image data. Wherein, the frame rate (Frame rate) is a measur...

Embodiment 2

[0040] refer to figure 2 , showing a flow chart of the steps of an embodiment of a method for setting shooting parameters of the present invention, which is applied to a mobile terminal with at least two cameras, the cameras include a main camera and a secondary camera, and the main camera is set according to the first A preset frame rate to output image data, the secondary camera is set to output image data according to a second preset frame rate, the method may specifically include the following steps:

[0041] Step 201, acquiring second image data output by the secondary camera according to a second preset frame rate;

[0042]In the embodiment of the present invention, the main camera and the sub-camera are set to output image data at different frame rates, wherein the second frame rate of the sub-camera is higher than the first frame rate of the main camera. For example, the main camera can be set to output image data at a frame rate of 30 frames per second, and the seco...

Embodiment 3

[0073] refer to Figure 4 , shows a structural block diagram of a mobile terminal embodiment of the present invention, the camera of the mobile terminal at least includes a main camera and a secondary camera, and the main camera is set to output image data according to a first preset frame rate, so The secondary camera is set to output image data according to a second preset frame rate, and the mobile terminal may specifically include the following modules:

Abstract

The embodiment of the invention provides a shooting parameter setting method and a mobile terminal. The shooting parameter setting method is applied to the mobile terminal having at least two cameras, the cameras comprise a main camera and an auxiliary camera, the main camera is configured to output image data according to a first preset frame rate, and the auxiliary camera is configured to output image data according to a second preset frame rate. The method comprises the following steps: obtaining second image data output by the auxiliary camera according to the second preset frame rate; calculating a calibration parameter by using the second image data; and setting shooting parameters of the main camera according to the calibration parameter. According to the shooting parameter setting method provided by the embodiment of the invention, the shooting parameters of the cameras are quickly set in this manner, thereby improving the shooting speed and improving the shooting user experience.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for setting shooting parameters and a mobile terminal. Background technique [0002] With the rapid development of smart mobile terminals such as mobile phones, the performance of camera photosensitive chips continues to improve, coupled with the portability of mobile terminals, cameras on mobile terminals often replace traditional cameras or even SLR cameras most of the time. The shooting applications of mobile terminals are becoming more and more extensive. [0003] The shooting speed is fast enough to bring users a pleasant feeling. The speed of the camera is already a relatively big pain point for users. Quick start, snapping, etc. have become an evaluation index for camera manufacturers. But at present, the cameras of general mobile terminals use the traditional 3A algorithm to maintain 3A stability. Specifically, the traditional 3A algorithm refers to an a...
