Embodiment 1

[0029] In preferred embodiment 1, the status information includes the motion status of the terminal.

[0030] The sensor on the terminal can perceive the motion state of the terminal, and then adjust the frame rate of the video recording of the terminal according to the motion state of the terminal. For example, the motion state of the terminal may be determined according to the speed or acceleration of the terminal. In general, the faster the motion speed is, the higher the frame rate of the video needs to be in order to ensure the quality of the video. Preferably, when the terminal is in a relatively static state, a lower video frame rate can be set; when the terminal is in a relatively moving state, a higher video frame rate can be set.

[0031] In order to reduce the frequency of adjusting the video frame rate, the speed or acceleration can be divided into multiple ranges, and different video frame rates can be set for each different range. In this case, the above step S...

Embodiment 2

[0033] In the second preferred embodiment, the status information includes the light intensity of the environment where the terminal is located.

[0034] In a preferred embodiment, the light intensity of the environment where the terminal is located is determined according to the acquired data; and the frame rate of the video recording of the terminal is adjusted according to the light intensity of the environment where the terminal is located.

[0035] In this embodiment, a video frame rate adjustment device is also provided, which is used to implement the above method. What has been explained in the above method will not be repeated here. The names of the modules in the device below should not be understood. To limit the module, for example, the adjustment module is used to adjust the frame rate of the terminal video recording according to the state information, and can also be expressed as "a method for adjusting the frame rate of the terminal video recording according to th...

Abstract

Disclosed are a method and device for adjusting the frame rate of video recording. The method comprises: acquiring data collected by a sensor of a terminal; determining state information in accordance with the data, wherein the state information is used for adjusting the frame rate of video recording of the terminal; and adjusting the frame rate of video recording of the terminal in accordance with the state information, thereby reducing the power consumption of the terminal. The present invention solves the problem in related art of additional power consumption because the frame rate of video recording is adjusted by means of dynamic adjustment of an image picture, reduces the power consumption of the video function, and improves the endurance capability of the terminal.

Description

technical field [0001] The present invention relates to the field of video, in particular to a method and device for adjusting video frame rate. Background technique [0002] In related technologies, terminal devices are used more and more, and the hardware capabilities of the terminal devices are also getting stronger. For example, current terminal devices are generally equipped with processors, cameras, sensors and other devices. It is precisely because of the addition of these devices that the terminal has a variety of functions, for example, the terminal has a camera function. [0003] Generally, the camera function of a terminal is only an auxiliary function. For example, in a smart phone or a tablet computer, the communication function (such as a call function or a data communication function) is its main function, and, due to the current mobile terminal Devices usually have typical features such as multi-core high-frequency processors, large screens, advanced graphi...
