Description
Technical field
The present invention relates to video playback field, particularly relate to control method and the system of the broadcasting at night of a kind of video.
Background technology
Popularizing of electronic equipment; increasing people uses electronic equipment; especially mobile terminal; but current mobile terminal not yet has again the function protected human eye, particularly at night; user is when using mobile terminal player; manually adjusting screen brightness can only reduce screen to the thorn of human eye along with swashing, this method regulates inconvenient, can not regulate screen intensity intelligently.
In prior art, some relevant technology have been had in TV industry, such as CN101090450A discloses a kind of implementation method and device of night mode of display equipment, by regulating the television image at night, to protect eyes: when TV is switched to Night, according to the associated analog amount of preset in advance value change TV, image or audio frequency are processed, but, the viewing TV if user starts shooting for second day by day, because the state of watching TV night can not meet demand when seeing TV daytime, watch under again must adjusting to adapt to daylight environment, the more important thing is, this technology only recognize night watching mode and conventional watching mode between the difference that exists, give the working mechanism matched with two kinds of watching modes, but the solution of watching mode is simple and crude for night, the direct adjusting screen brightness of parameter only by preset in advance, the mode of contrast and volume, the display effect of screen at night can not be improved, because the external environment condition light brightness at daytime and night is different, when watching night, human eye is not only have requirement to screen intensity, also need the monochrome information of video image to coordinate with each side such as colouring information and pixel and just can reach reasonable viewing effect.Particularly at mobile terminal, mode conventionally manually reduces screen intensity, still very large to the stimulation of human eye, and changes the sense of discomfort that also can cause a period of time to user due to unexpected brightness.
The present invention proposes control method and the system of the broadcasting at night of a kind of video, environmentally can regulate monochrome information and the chrominance information of video playback picture frame by bright intensity automatic order, with eye, protection is formed to the user watching video night.
Summary of the invention
For overcoming the deficiencies in the prior art; the object of the invention is: control method and system that the broadcasting at night of a kind of video is provided; environmentally can regulate monochrome information and the chrominance information of video playback picture frame by bright intensity automatic order, with eye, protection is formed to the user watching video night.
In order to solve the technical problem in background technology, the invention provides the control method of a kind of video broadcasting at night, comprising the following steps:
S1, under night play mode, obtain video single-frame images information successively according to video playback order, calculate brightness value and the chromatic value of each pixel in described image;
The brightness range that S2, the brightness value reducing each pixel extremely set;
S3, the chrominance information of each pixel to be compensated;
Image after S4, Drazin inverse;
S5, step according to S2 to S4, process the multiple image of video successively until video playback terminates.
Preferably, described step S2 is specially: the brightness value of each pixel is reduced 85%-95%.
Correspondingly, described step S3 is specially: mix in proportion with chrominance information the monochrome information after each pixel adjustment, and the proportion of monochrome information and chrominance information is 0.85:0.15 to 0.95:0.05.
Alternatively, by defining the time period mode of Night, sensors sense environmental brightness mode or manually opened mode, video play mode is switched to play mode at night.
Particularly, described step S4 also comprise to the audio-frequency information of video carry out flat regulate arrange, and synchronism output regulate after image information and audio-frequency information.
Present invention also offers the regulating system of a kind of video broadcasting at night, comprise with lower module:
Decoder module, for obtaining the single-frame images of the video under play mode at night;
Computing module, for calculating pixel brightness value and the chromatic value of obtained image;
Luminance adjustment module, the brightness range that the brightness value for reducing each pixel extremely sets;
Chromatic compensation module, for compensating the chrominance information of each pixel;
Output module, for having exported the video image that YC regulates continuously in units of frame.
Preferably, the brightness value of each pixel is reduced 85%-95% by described luminance adjustment module.
Further, described chromatic compensation module mixes with chrominance information in proportion to the monochrome information after each pixel adjustment, and the proportion of monochrome information and chrominance information is 0.85:0.15 to 0.95:0.05.
Alternatively, by defining the time period mode of Night, sensors sense environmental brightness mode or manually opened mode, video play mode is switched to play mode at night.
Preferably, the regulating system of video of the present invention broadcasting at night also comprises audio frequency adjustment module, regulates setting, the image information after described output module synchronism output regulates and audio-frequency information for carrying out flat to the audio-frequency information of video.
Adopt technique scheme, the control method of video of the present invention broadcasting at night and system environmentally can regulate monochrome information and the chrominance information of video playback picture frame by bright intensity automatic order, form protection to the user watching video night with eye.
