Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is a kind of flow diagram of method for adjusting screen intensity provided in an embodiment of the present invention, including walks as follows
Suddenly：
Step S101：In video display process, the brightness regulation information in video frame tagging in the video is obtained.
Wherein, brightness regulation information is used to identify a kind of bright, common or brightness degree in the dark, every kind of brightness degree difference
A corresponding default screen brightness value.
In a kind of embodiment of the present invention, brightness regulation information is regarding according to each video by server
Frequency brightness is added in advance.
Furthermore, server adds brightness regulation information in advance according to the luminance video of each video, including：
A, to each video, the average brightness value of each basic cycle in each video flowing is calculated.
Wherein, the basic cycle is default fixed video duration, for example, being set according to the empirical parameter during video production
It is a basic cycle to put 1 second, or, sets every 24 video frame basic for one according to the empirical parameter during video production
Cycle.
In a kind of embodiment of the present invention, the average brightness of each basic cycle in each video flowing is calculated
Value, can usually use average weighted method.By the brightness value and the video that calculate each video frame in the basic cycle
Weights corresponding to the brightness value of frame, obtain the average brightness value of basic cycle.
It should be noted that the video frame images in each video flowing are quantified previously according to gradation of image test card
Processing, by the brightness value within the brightness specification to 0-10 of the video frame images, for each frame video image in video flowing,
The brightness value of the quantization of specific one.
