Effect, improves Consumer's Experience.
Embodiment two is a kind of method for adjusting luminance video provided in an embodiment of the present invention, shown in reference picture 2,
This method includes：
201st, the brightness of current video frame is obtained.
Specifically, according to the brightness of predeterminable area in current video frame, obtaining the brightness of current video frame.
Wherein, predeterminable area can be inside frame of video 2/3rds region in current video frame, then this is obtained
Taking the process of the brightness of current video frame can be：
Current video frame is divided into inside and outside two parts, internal area accounts for 2/3rds of whole video frame size,
Outside is the region outside inside；
Brightness detection is carried out respectively to the inside and outside of current video frame, according to testing result, by brightness compared with
Most brightness value is as the brightness of the current video frame, and the brightness can represent with x.
It should be noted that the predeterminable area can be inside frame of video 2/3rds region or
3/4ths internal regions or the half domain of inside, can also be other, the present invention
Embodiment is not limited to the area shared by inside, and the area of the shared whole frame of video in the inside can basis
Practical application is specifically limited.
The predeterminable area can be the circle inside the rectangle or overall frame of video of frame of video whole interior
Shape or elliptical region, in addition to this it is possible to be irregular shape or hexagon inside overall frame of video etc.
Other shapes, the embodiment of the present invention is not limited to this, wherein, if the region is frame of video whole interior
Rectangle, the rectangle can be and integrally long and width equal proportion the rectangle of frame of video.
In addition, the predeterminable area can also be the region for including face in frame of video.
Exemplary, if the predeterminable area is the rectangle of frame of video whole interior, the predeterminable area is referred to
The region in video clip in Fig. 3 shown in a；If the predeterminable area is the ellipse of frame of video whole interior,
The predeterminable area is referred in Fig. 3 the region in the video clip shown in b；If the predeterminable area is video
Frame in includes the region of face, and the predeterminable area is referred in Fig. 3 the region in the video clip shown in c.
By the way that frame of video is divided into inside and outside two parts, and it regard the brightness value of brightness major part as the frame of video
Brightness, compared to traditional when the luminance contrast in image or frame of video is larger, to image or frame of video
Overall brightness detected and adjusted, the problem of contrast is uncoordinated after the regulation of appearance, thereby using
The method that inventive embodiments are provided, further increases the accuracy of luminance video regulation, improves brightness tune
The effect of section.
After the brightness for obtaining current video frame, method also includes：
It is bright frame or spacer to determine the current video frame.
Specifically, the process can be：
If the brightness of all frame of video in the default consecutive intervals time is both greater than the second preset value, it is determined that should
Last frame frame of video in the default consecutive intervals time is bright frame；If the institute in the fruit default consecutive intervals time
The brightness for having frame of video is both less than or equal to the second preset value, it is determined that in the default consecutive intervals time
Last frame video is spacer；
Exemplary, the predetermined interval can be 3s, and second preset value can be brightness value 64.
By determining that current video frame is bright frame or spacer, enabling the frame of video to being bright frame and spacer
It is adjusted, so as to further increase the accuracy of luminance video regulation, is carried by different regulation strategies
The high effect of brightness regulation so that the brightness after regulation is more applicable for frame of video instantly.
202nd, the regulated value of the brightness to current video frame is obtained.
Specifically, obtaining the regulated value of the brightness to current video frame, the regulated value of the brightness can use m tables
Show, exemplary, the regulated value of the brightness can be acquisition that user is manually entered or automatic,
The embodiment of the present invention to the specific acquisition modes of the regulated value of the brightness without limitation.
203rd, the regulation plan of brightness is determined according to the relativity of the brightness of the regulated value of brightness and current video frame
Slightly.
If specifically, the ratio of the brightness of the regulated value and current video frame of brightness is pre- less than or equal to first
If value, it is determined that regulation strategy is the first regulation strategy, performs step 204；Otherwise, if the regulated value of brightness
It is more than the first preset value with the ratio of the brightness of current video frame, it is determined that regulation strategy is the second regulation strategy,
Perform step 205.
Wherein, first preset value can be 2 in actual applications, i.e.,：
During m≤2x, it is determined that regulation strategy is the first regulation strategy, performs step 204；
During m ＞ 2x, it is determined that regulation strategy is the second regulation strategy, performs step 205.
The regulation plan of brightness is determined by the relativity of the brightness of regulated value and current video frame according to brightness
Slightly so that it is determined that regulation strategy be more applicable for video condition instantly, improve luminance video regulation standard
True property so that the luminance video after regulation is truer, improves user of the user during instant video
Experience.
If it is the first regulation strategy the 204, to adjust strategy, the brightness after regulation is calculated using the first preset algorithm.
Specifically, first preset algorithm can be following preset formula：
Y=ax2+bx+c
Wherein x be the current video frame brightness, a, b, c be according to regulated value m calculate parameter, a, b, c can
To be that by three points (0,0), (x, m), (255,255) substitute into the first preset formula and calculate what is obtained.
It should be noted that being the first regulation strategy as m≤2x for bright frame and spacer, pass through
One preset algorithm calculates the brightness value after regulation.
If it is the second regulation strategy the 205, to adjust strategy, the brightness after regulation is calculated using the second preset algorithm.
If specifically, the current video frame is bright frame, the brightness after regulation is calculated using the second preset algorithm
Process include：
Calculate

By point (0,0), (x, 2x), (255,255), (0,0), (2x, 4x), (255,255) ...
(0,0), (Cx, m), (255,255) respectively substitute into above-mentioned formula in, a is calculated respectively1, b1, c1
To ac, bc, cc；
By yCTo y2Substitute into y1It is iterated, obtains y1=d1x2C+d2x2C-1+...d2C x+d2C+1；
By calculating obtained y1For the brightness after the bright frame regulation.
If the current video frame is spacer, the process bag of the brightness after regulation is calculated using the second preset algorithm
Include：
Calculate
Calculated according to C：y1=a1x2+b1x+c1, y2=a2x2+b2x+c2…yC=aCx2+bCx+cC；
By point (0,0), (x, 2x), (255,255), (0,0), (2x, 4x), (255,255) ...
(0,0), (Cx, m), (255,255) respectively substitute into above-mentioned formula in, a is calculated respectively1, b1, c1
To ac, bc, cc；
By yCTo y2Substitute into y1It is iterated, obtains y1=d1x2C+d2x2C-1+...d2C x+d2C+1。
It should be noted that step 204 and step 205 are to realize the regulation policy calculation according to brightness with working as
The process of brightness after the corresponding regulation of brightness of preceding frame of video, in addition to aforesaid way, can also pass through
Other modes realize the process, and the embodiment of the present invention is not limited to specific mode.
According to the brightness after the regulation corresponding with the brightness of current video frame of the regulation policy calculation of brightness, not only
During so that part or all of region in the video frame is dimmed or fuzzy, the brightness of frame of video is maintained, together
When regulation current video frame brightness for regulation after brightness, further increase luminance video regulation it is accurate
Property, the effect of brightness regulation is improved, Consumer's Experience is improved.
206th, judge current video frame for bright frame or spacer.
