Formula is for carrying out enhancing processing to different video frames.Specifically, being arranged successively when choosing enhances processing mode for video
Each video frame, can intersect choose first enhancing processing mode and second enhancing processing mode each sub- enhancing processing side
Formula.
For example, second enhancing processing mode son enhancing processing mode be k kind, as soon as by video frame be divided into n frame be group,
It is to say, the 1st frame video frame to n-th frame is one group, and (n+1)th to 2n is one group, and 2n+1 to 3n is one group, and so on, n
More than or equal to k+1.Then for each group of video frame, each frame video frame can be from the first enhancing processing mode and the second enhancing place
Corresponding enhancing processing mode, and the first enhancing processing mode and second are chosen in the k seed enhancing processing mode of reason mode
The k seed enhancing processing mode of enhancing processing mode is all selected.The selection rule of each group video frame can be consistent, can also be with
It is inconsistent.With the son enhancing processing mode of the second enhancing processing mode for 2 kinds, 4 frame video frames are divided into for one group, then one group of view
The first and second frame in frequency frame can choose the first enhancing processing mode, and third and the 4th frame video frame can be selected respectively
Two seeds are taken to enhance processing mode.
For another example, the son enhancing processing mode of the second enhancing processing mode is k kind, and choosing enhancing processing mode can be, the
One frame video frame chooses the first enhancing processing mode, and the 2nd to+1 frame of the kth each height for choosing the second enhancing processing mode respectively increases
Strong processing mode；+ 2 frame video frame of kth chooses the first enhancing processing mode, and kth+3 to kth+3+k-1 frame chooses the second increasing respectively
Each height of strong processing mode enhances processing mode, and so on.
Present invention also provides a kind of embodiments, and in this embodiment, the second enhancing processing mode also may include
Processing mode to video frame without enhancing processing.
In this embodiment, if the second enhancing processing mode is a kind of processing mode, the first enhancing processing mode is one
Kind processing mode includes then the corresponding non-low-power consumption enhancing of the first enhancing processing mode to the processing mode of video frame and is not increased
By force.For example, the video frame selection described second at interval of default frame number enhances processing mode, it is every if default frame number is 1
It being handled every a frame video frame without enhancing, the video frame being spaced carries out enhancing processing by the first enhancing processing mode,
That is the enhancing processing interval of video frame carries out, frame video frame enhancing, a frame video frame does not enhance, successively carries out.If pre-
If frame number is not 1, then in the video frame being arranged successively, a frame video frame without enhancing, adjacent default frame number video frame into
Row enhancing processing, then next frame video frame, without enhancing, following adjacent default frame number carries out enhancing processing, successively class
It pushes away.
In this embodiment, if the second enhancing processing mode includes more seed enhancing processing modes, more seed enhancings
One of processing mode son enhancing processing mode can be without enhancing.
In the embodiment of the present application, the figure that the first processing enhancing processing mode and the second enhancing processing mode specifically include
As Processing Algorithm does not limit.Specifically, calculation of the algorithm complexity of the first enhancing processing mode than the second enhancing processing mode
Method complexity is high, corresponding, and the treatment effect that the treatment effect of the first enhancing processing mode enhances mode of haveing broken up than second is more preferable,
The power consumption of first enhancing processing mode is also higher than the second enhancing processing mode.
Optionally, it can be, the first enhancing processing mode includes more image processing algorithms preferably to improve video
Image quality, and the image processing algorithm that the second enhancing processing mode includes is fewer than the first enhancing processing mode.Such as, the first enhancing is handled
The enhancing processing of mode includes three kinds or two kinds in Denoising Algorithm, saturation degree enhancing and contrast enhancement algorithms, and second
The enhancing processing costs of enhancing processing mode includes Denoising Algorithm, saturation degree enhancing and one of contrast enhancement algorithms, such as
Denoising Algorithm.The enhancing processing of either the first enhancing processing mode includes that Denoising Algorithm, saturation degree enhancing and contrast increase
Three kinds in strong algorithms, and the enhancing processing costs of the second enhancing processing mode includes Denoising Algorithm, saturation degree enhancing and comparison
Two kinds in degree enhancing algorithm.
Wherein, specifically corresponding image processing algorithm does not limit every kind of algorithm in the embodiment of the present application.Such as it denoises
Algorithm can be the image processing algorithm intact to detailed information such as image borders, e.g., former based on local space continuity
Guiding filtering algorithm then, while the filter bilateral filtering of pixel space difference and strength difference is considered, it takes full advantage of
The self-similarity of whole image and NLM (Non-Local Means, non-local mean) Image denoising algorithm of redundancy.Example
Algorithm as contrast enhances can be Adaptive contrast enhancement algorithm (ACE, Adaptive Contrast
Enhancement), histogram equalization (Histogram Equalization) and Histogram Matching (Histogram
Matching) etc..Such as the algorithm of saturation degree enhancing can be the colour component increased in video frame, e.g., video frame passes through RGB
When expression, each Color Channel of RGB is turned up respectively；Or it is not very intuitive for adjusting brightness and saturation degree in rgb color space, and
HSL color mode very visual representation can go out the saturation degree of each pixel, can then reconvert arrive by the pixel RGB values of image
HSL color mode obtains saturation degree S (Saturation), and saturation degree is turned up by adjusting the value of S.Again by video frame adjusted
Rgb color mode is transformed into for showing from HSL color mode.
Optionally, the number of iterations for being also possible to algorithm in the first enhancing processing mode is handled greater than first enhancing
Enhance the number of iterations of Processing Algorithm in mode.Corresponding first enhancing processing mode is better than the treatment effect of video frame image quality
Second enhancing processing mode, such as clarity are higher, and saturation degree is higher, and contrast is stronger etc., corresponding first enhancing processing side
The power consumption of formula is also higher.
Optionally, for the image procossing of same purpose, first enhances in processing mode using the higher algorithm of complexity.
For example, can connect using based on local space in the second enhancing processing mode for the image processing algorithm of denoising
The guiding filtering algorithm of continuous property principle, NLM (Non-Local Means, non-local mean) Image denoising algorithm etc. is conventional to be gone
It makes an uproar calculation, still, conventional Denoising Algorithm still may make image impairment part details.
First enhancing processing mode can be more complicated but more denoise the better Denoising Algorithm of effect, for example, only to view
Part in frequency frame other than edge details feature is denoised by Denoising Algorithm, without carrying out to the edge feature in video frame
Processing, to retain the good edge details feature of image.
Specifically, the image processing algorithm denoised in the first enhancing processing mode can be, edge detection algorithm is first passed through
Obtain the marginal portion in video frame.Wherein, specific edge detection algorithm does not limit in the embodiment of the present application, such as can
To be difference edge detection, Reborts operator, Sobel operator, Prewitt operator, Luo Baici overlapping edges detection (Roberts
Cross operator), any one in Kirsch operator and Laplace operator etc..
Will test the edge extracting obtained from video frame again to come out, i.e., by video frame be divided into marginal portion and edge with
Outer part.Specifically, the video frame can be cut to first according to edge detection as a result, by trimming algorithm
Divide and second part, the first part are the marginal portion, the second part is the portion other than the marginal portion
Point.Specific trimming algorithm does not limit in the embodiment of the present application, it is all can be by edge that edge detection arrives from video frame
In cut out, make that video frame is tailored to first part and the trimming algorithm of second part is ok, such as Cohen-
Sutherland trimming algorithm.Or directly according to edge detection results, will be expressed as in edge detection the pixel at edge from
It is extracted in video frame, video frame is made to be divided into first part and second part.
Denoising is carried out to second part by Denoising Algorithm again.Specific Denoising Algorithm is in the embodiment of the present application simultaneously
Do not limit, can be it is any meet to video frame carry out denoising image processing algorithm, such as above-mentioned guiding filtering algorithm,
Bilateral filtering algorithm and NLM algorithm etc. are also possible to other Denoising Algorithms, such as neighborhood averaging, median filtering, low-pass filtering
Equal filter in spatial domain Denoising Algorithm, Fourier transform, Walsh-Hadanjard Transform, cosine transform, Karhunen-Loeve transformation and small echo become
Change equal transform domains filtering and noise reduction algorithm etc..
The second part after the first part and denoising is combined into image again, is handled as the video frame enhancing
Video frame afterwards.Specifically, first part and second part are combined into a frame image, make the figure of first part after combining
As in, corresponding position is first part position in cropped video frame；It is corresponding in the image of second part after combining
Position be second part position in cropped video frame.That is, combination after image in, first part be the figure
Edge feature as in, second part are the part other than edge feature.Using the image after combination as the view after video source modeling
Frequency frame.
In the first enhancing processing mode, the relatively conventional denoising algorithm of the complexity of denoising algorithm is complicated
Du Genggao, power consumption is bigger, but after the edge details part in video frame is cut, goes to the part of non-edge details
It makes an uproar, also removes the edge detail information of image so as to avoid Denoising Algorithm, denoising effect is more preferable.After denoising, then by side
Edge detail section is combined into video frame with the part of non-edge details after being denoised, and forms enhanced video frame, makes video
Edge noise will not amplify in enhanced video frame, and eliminate the noise in video frame.
It for another example, can be using normal in the second enhancing processing mode for the image processing algorithm being sharpened to video frame
The Edge contrast mode of rule, such as Grads Sharp, Laplace operator.Video frame can be promoted due to being sharpened to video frame
Clarity, but sharpen enhance noise, amplify edge noise, keep the information of edge non-video itself more, side
Edge details is fuzzyyer.
Therefore, the first enhancing processing mode can effect be more preferable and the Processing Algorithm of less pull-up noise is to view by sharpening
Frequency frame is handled.Specifically, the algorithm sharpened in the first enhancing processing mode may is that and first pass through edge detection algorithm acquisition
Marginal portion in video frame.The video frame is cut to first part and second part again, the first part is institute
Marginal portion is stated, the second part is the part other than the marginal portion.By Image Sharpening Algorithm to described second
Dividing and is sharpened processing, specific Edge contrast algorithm does not limit in the embodiment of the present application, for example, it may be, gradient is sharp
Change, Laplace operator etc..Second part after first part and sharpening is combined into image, is enhanced as the video frame
Video frame afterwards.
First enhancing processing mode uses the Processing Algorithm of pull-up noise less than the second enhancing processing mode to be sharpened
Processing, still, corresponding, it is higher that the power dissipation ratio second in the first enhancing processing mode treatment process enhances processing mode.
The higher image processing algorithm of algorithm complexity used in specific first enhancing processing mode carries out video frame
Enhance in the embodiment of the present application and is not listed one by one.First enhancing processing mode is obtained more preferable by the higher algorithm of complexity
Video treatment effect, but relative to second enhancing Processing Algorithm have higher power consumption.

For choosing the video frame of the second enhancing processing mode, enhancing processing is carried out with the second enhancing processing mode.It should be understood that if
Second enhancing processing mode includes more seed enhancing processing modes, then chooses the video frame to corresponding son enhancing processing mode, with
The son enhancing processing mode of selection is handled.If the second enhancing processing mode includes the place to video frame without enhancing processing
Reason mode is then chosen the video frame to the processing mode without enhancing, is handled without enhancing.
In the embodiment of the present application, the selection of the enhancing processing mode of video frame can carry out display enhancing with to video frame
Processing is synchronous to be carried out.That is, the enhancing processing of video frame can be to be enhanced while choosing enhancing processing mode
Processing.For example, can then start to pass through selection to the video frame after choosing corresponding enhancing processing mode for a frame video frame
Enhancing processing mode carries out enhancing processing.
In the embodiment of the present application, if the second enhancing processing mode includes the processing side to video frame without enhancing processing
Formula, in order to accelerate the processing speed to video frame, can will the frame of video picture quality enhancement be placed on inside GPU and carry out off screen rendering
Processing, the video frame not enhanced the end CPU by screen rendering processing, so that power consumption obtains while guaranteeing video picture quality enhancement
To reduction.After the completion of rendering, video frame is shown by display screen.
In the embodiment of the present application, the first enhancing processing mode is chosen to partial video frame, rest part video frame chooses the
Two enhancing processing modes.First enhancing processing mode is the enhancing processing mode under non-low-power consumption enhancing, can be electronic equipment
The best enhancing processing mode of the reinforcing effect that can achieve.The power consumption of second enhancing processing mode is lower than the first enhancing processing side
Formula, so that it is lower to make the enhancing of video handle power consumption, simultaneously because partial video frame enhances at processing mode still through first
Reason, the overall synergistic effect of video are still preferable.In this embodiment, it keeps reducing view while video good reinforcing effect
Power consumption when frequency enhancing processing.
It should be understood that in the embodiment of the present application, increasing if choosing power consumption to all video frames of video frame lower than first
