Abstract

Provided are a method and device for adjusting a frame rate of video recording. According to the method, data collected by a sensor of a terminal is acquired; state information is determined according to the acquired data, wherein the state information is used for adjusting a frame rate of video recording of the terminal; the frame rate of video recording of the terminal is adjusted according to the determined state information, thereby reducing the power consumption of the terminal. The technical solution solves the problem in related art of additional power consumption because the frame rate of video recording is dynamically adjusted based on features of an image frame, reduces the power consumption of a video recording function, and improves the endurance capability of the terminal.

First claim

What is claimed is:

1. A method for adjusting a frame rate of video recording, comprising:
acquiring data collected by a sensor of a terminal;
determining state information according to the acquired data; and
adjusting a frame rate of video recording of the terminal according to the determined state information, wherein the determined state information contains: a speed or acceleration of the terminal, adjusting the frame rate of video recording of the terminal according to the speed or the acceleration of the terminal comprises:
determining a range in which the speed or the acceleration of the terminal falls, wherein multiple ranges for speed or acceleration of the terminal are formed in advance, and a frame rate of video recording is set for a respective one of the multiple ranges; and adjusting the frame rate of video recording of the terminal according to the frame rate of video recording corresponding to the range in which the speed or the acceleration of the terminal falls.

2. The method as claimed in claim 1 , wherein determining the state information according to the acquired data, and adjusting the frame rate of video recording of the terminal according to the determined state information comprises:
determining a moving state of the terminal according to the acquired data; and
adjusting the frame rate of video recording of the terminal according to the determined moving state of the terminal.

3. The method as claimed in claim 2 , wherein adjusting the frame rate of video recording of the terminal according to the determined moving state of the terminal comprises:
adjusting the frame rate of video recording of the terminal according to a speed or acceleration of the terminal, wherein the higher the speed or the acceleration is, the higher the frame rate of video recording is.

4. The method as claimed in claim 1 , wherein determining the state information according to the acquired data, and adjusting the frame rate of video recording of the terminal according to the determined state information comprises:
determining, according to the acquired data, light intensity of an environment which the terminal is in; and
adjusting the frame rate of video recording of the terminal according to the determined light intensity of the environment which the terminal is in.

5. A device for adjusting a frame rate of video recording, comprising:
an acquiring component, which is configured to acquire data collected by a sensor of a terminal;
a determining component, which is configured to determine state information according to the acquired data; and
an adjusting component, which is configured to adjust a frame rate of video recording of the terminal according to the determined state information, wherein the determined state information contains: a speed or acceleration of the terminal, the adjusting component comprises: a determining element, which is configured to determine a range in which the speed or the acceleration of the terminal falls, wherein multiple ranges for speed or acceleration of the terminal are formed in advance, and a frame rate of video recording is set for a respective one of the multiple ranges; and
an adjusting element, which is configured to adjust the frame rate of video recording of the terminal according to the frame rate of video recording corresponding to the range in which the speed or the acceleration of the terminal falls.

6. The device as claimed in claim 5 , wherein
the determining component is configured to determine a moving state of the terminal according to the acquired data; and
the adjusting component is configured to adjust the frame rate of video recording of the terminal according to the determined moving state of the terminal.

7. The device as claimed in claim 6 , wherein the adjusting component is configured to adjust the frame rate of video recording of the terminal according to a speed or acceleration of the terminal, wherein the higher the speed or the acceleration is, the higher the frame rate of video recording is.

8. The device as claimed in claim 5 , wherein
the determining component is configured to determine, according to the acquired data, light intensity of an environment which the terminal is in; and
the adjusting component is configured to adjust the frame rate of video recording of the terminal according to the determined light intensity of the environment which the terminal is in.
