Problems solved by technology

[0002] During the real-time video interaction of the user, when the intensity of the ambient light source of any one of the video interaction parties is weak, it will cause some or all areas in the video frame corresponding to the user's face in the video to become dark or blurred, affecting the user's vision. Real-time video interaction, thereby reducing the user's interactive experience
[0003] When some or all areas in the video frame become dark or blurred due to weak light source intensity, the user can only overcome the above problems by adjusting the light source intensity in the environment or moving to a place with stronger light intensity, but in practice In the application, the size of the light source in the user's environment is not adjustable or inconvenient to adjust, and the user moves to a place with strong light intensity, which will also cause inconvenience to the user during the real-time video process; in the actual use process, the above two solutions Both solutions will reduce the user experience of users in the process of real-time video

Embodiment 1

[0069] Embodiment 1 is a method for adjusting video brightness provided by the embodiment of the present invention, refer to figure 1 As shown, the method includes:

[0070] 101. Acquire the brightness of the current video frame.

[0071] Specifically, the brightness of the current video is acquired according to the brightness of a preset area in the current video frame.

[0072] 102. Acquire an adjustment value of the brightness of the current video frame.

[0073] 103. Determine a brightness adjustment strategy according to a contrast relationship between the brightness adjustment value and the brightness of the current video frame.

[0074] Specifically, if the ratio of the brightness adjustment value to the brightness of the current video frame is less than or equal to the first preset value, the adjustment strategy is determined to be the first adjustment strategy; otherwise, the adjustment strategy is determined to be the second adjustment strategy.

[0075] 104. Calc...

Embodiment 2

[0084] Embodiment 2 is a method for adjusting video brightness provided by the embodiment of the present invention, refer to figure 2 As shown, the method includes:

[0085] 201. Acquire the brightness of the current video frame.

[0086] Specifically, the brightness of the current video frame is acquired according to the brightness of a preset area in the current video frame.

[0087] Wherein, the preset area in the current video frame can be the inner two-thirds area of ​​the video frame, then the process of obtaining the brightness of the current video frame can be:

[0088] Divide the current video frame into inner and outer parts, the inner area accounts for two-thirds of the entire video frame size, and the outer area is the area outside the inner area;

[0089] Luminance detection is performed on the inside and outside of the current video frame, and according to the detection results, the luminance value of the larger part of the luminance is used as the luminance o...

Embodiment 3

[0150] Embodiment 3 is an electronic device 4 provided by the embodiment of the present invention, refer to Figure 4 As shown, the electronic equipment includes:

[0151] Brightness acquiring module 41, is used for acquiring the brightness of current video frame;

[0152]An adjustment value acquisition module 42, configured to acquire an adjustment value to the brightness of the current video frame;

[0153] Strategy generating module 43, for determining the adjustment strategy of brightness according to the contrast relationship between the adjustment value of brightness and the brightness of current video frame;

[0154] The processing module 44 is used to calculate the adjusted brightness corresponding to the brightness of the current video frame according to the adjustment strategy of the brightness;

[0155] An adjustment module 45, configured to adjust the brightness of the current video frame to the adjusted brightness.

[0156] Optionally, the brightness acquisitio...

Abstract

The invention discloses a method for adjusting video brightness and an electronic device, and belongs to the field of videos. The method comprises the following steps: obtaining the brightness of a current video frame; obtaining an adjustment value of the brightness of the current video frame; determining an adjustment strategy of the brightness according to a contrast relation between the adjustment value of the brightness and the brightness of the current video frame; calculating adjusted brightness corresponding to the brightness of the current video frame according to the adjustment strategy of the brightness; and adjusting the brightness of the current video frame to the adjusted brightness. According to the method provided by the invention, the adjusted brightness corresponding to the brightness of the current video frame is calculated according to the adjustment strategy of the brightness, therefore when a part of or all areas in the video frame become dark or fuzzy, the brightness of the video frame is kept, the obtained adjusted brightness is better suitable for the current video condition, the accuracy of adjusting the video brightness is improved, the adjusted video brightness is truer, the user experience in an instant video process is improved, and the brightness adjustment effect is improved.

Description

technical field [0001] The invention relates to the video field, in particular to a method and electronic equipment for adjusting video brightness. Background technique [0002] During the real-time video interaction of the user, when the intensity of the ambient light source of any one of the video interaction parties is weak, it will cause some or all areas in the video frame corresponding to the user's face in the video to become dark or blurred, affecting the user's vision. Real-time video interaction, thereby reducing the user's interactive experience. [0003] When some or all areas in the video frame become dark or blurred due to weak light source intensity, the user can only overcome the above problems by adjusting the light source intensity in the environment or moving to a place with stronger light intensity, but in practice In the application, the size of the light source in the user's environment is not adjustable or inconvenient to adjust, and the user moves to...
