Embodiment 1

[0042] See figure 1 , figure 1 It is a flow chart of the first preferred embodiment of the frame rate reduction method of the present invention. Such as figure 1 As shown, a frame rate reduction method for taking pictures, wherein, comprising the following steps:

[0043] Step S100, obtain the preview frame rate of the current environment through the camera preview, and collect the exposure information of each frame of data in real time.

[0044] In the embodiment of the present invention, in the preview callback thread of the mobile terminal, the data of each frame is fed back by metadata, and the feedback information contains the required exposure information; storage; the exposure information includes exposure duration, sensitivity value and exposure stability mark; when the exposure information is unstable, the exposure information is cleared; at the same time, when obtaining the exposure information, it is also necessary to collect the frame rate information, and the e...

Embodiment 2

[0088] The embodiment of the present invention also provides a mobile terminal, such as figure 2 As shown, the mobile terminal in this embodiment of the present invention may be a mobile phone (or a tablet computer), wherein the mobile terminal in this embodiment includes a processor 10 and a memory 20 connected to the processor 10;

[0089] The memory 20 stores a reduced frame rate photographing program, which is used to implement the reduced frame rate photographing method when executed by the processor 10; the details are as described above.

Embodiment 3

[0091] A storage medium, wherein the storage medium stores a reduced frame rate photographing program, and the reduced frame rate photographing program is used to implement the reduced frame rate photographing method when executed by the processor 10; the details are as described above.

[0092] To sum up, the present invention discloses a method for taking pictures with reduced frame rate, a mobile terminal, and a storage medium. The method includes: obtaining the preview frame rate of the current environment through camera preview, and collecting the exposure information of each frame of data in real time; According to the exposure information and the preview frame rate, it is judged whether the current photographing environment is a low-light environment with a predetermined value; when it is judged that the current photographing environment is a low-light environment with a predetermined value, modify the exposure parameters according to a preset algorithm, and The paramete...

Abstract

The invention discloses a frame-lowering photographing method, a mobile terminal and a storage medium. The method includes: using a camera to preview so as to obtain the preview frame rate of a current environment, and collecting the exposure information of each frame of data in real time; judging whether the current photographing environment is a preset-value low-light environment or not according to the exposure information and the preview frame rate; if so, modifying exposure parameters according to a preset algorithm, and outputting corresponding frame data according to the exposure parameters; selecting the frame data with the exposure time satisfying a preset value, and outputting an image according to the selected frame data. The method has the advantages that the original camera isused to output high-quality pictures by lowering frame rate, the problem that pictures are poor in sharpness and have many noise points under a low-light environment is solved from the source, the quality of the pictures is increased, and use convenience is brought to users.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method for taking pictures with a lower frame rate, a mobile terminal and a storage medium. Background technique [0002] The Android operating system is an intelligent mobile terminal operating system launched by Google. In recent years, with the development of technologies such as mobile terminal hardware and software, mobile terminal camera applications have become more and more extensive; but in low-light environments , especially in the night scene, due to the limitations of the hardware of the mobile terminal itself and the limitations of the lighting factors of the environment, when shooting, there will be a phenomenon of poor clarity and high noise in the photo. [0003] Therefore, it is particularly important for users to improve the quality of taking pictures in low light; in the current technology, although the multi-frame synthesis software technolo...
