Referring to Fig. 3, Fig. 3 shows the flow diagram of the method for processing video frequency of another embodiment of the application offer.
It will be explained in detail below for process shown in Fig. 3, the method can specifically include following steps:
Step S210: when electronic equipment operation has video resource, the light of the electronic equipment local environment is detected
Brightness.
Step S220: judge whether the brightness is greater than default brightness.
Wherein, the specific descriptions of step S210- step S220 please refer to step S110- step S120, and details are not described herein.
Step S230: when the brightness is greater than the default brightness, to the picture material in the video resource
Tone mapping processing is carried out, and the current screen brightness of the electronic equipment is promoted into preset ratio and obtains the first screen
Brightness.
In the present embodiment, while carrying out tone mapping processing to the picture material in video resource, may be used also
To promote the current screen brightness of electronic equipment, as a kind of mode, the current screen brightness of electronic equipment is pressed into preset ratio

Except the screen intensity for rising electronic equipment, picture material can also be optimized according to video enhancement algorithm is preset, wherein institute
State picture material optimization may include exposure enhance, remove dryness, edge sharpening, contrast increase or saturation degree increase in extremely
Few one kind.
Specifically, the picture material in the video resource of electronic equipment operation is to pass through decoded picture material, due to
Picture material after decoding is that the data of RGBA format need to optimize to picture material by the number of RGBA format
According to HSV format is converted to, specifically, the histogram of picture material is obtained, statistics with histogram is obtained RGBA format
Data are converted to the parameter of HSV format, and the data of RGBA format are being converted to HSV format according to the parameter.
Wherein, exposure enhances, and for improving the brightness of image, then can be handed over brightness value by the histogram of image
The region at bottom increases brightness value, and alternatively, it is also possible to be to increase brightness of image by Nonlinear Superposition, specifically, I expression will be located
The darker image of reason, T indicates that treated brighter image, then the mode of exposure enhancing is T (x)=I (x)+(1-I
(x))*I(x).Wherein, T and I is the image of [0,1] value.If good algorithm can be with successive ignition for primary effect.
Wherein, the noise for removing image is denoised to picture material, specifically, image is normal during generation and transmission
Chang Yin by various noises interference and influence but image deterioration, this will produce the processing of subsequent image and image vision effect
Raw adverse effect.There are many noise type, such as: electrical noise, mechanical noise, interchannel noise and other noises.Therefore, in order to inhibit
Noise, improving image quality, convenient for higher level processing, it is necessary to which noise suppression preprocessing is carried out to image.From the probability of noise point
From the point of view of cloth situation, Gaussian noise, rayleigh noise, gamma noise, index noise and Uniform noise can be divided into.
It specifically, can be by Gaussian filter to image denoising, wherein Gaussian filter is a kind of linear filter,
Noise, smoothed image can effectively be inhibited.Its action principle is similar with mean filter, is all the picture taken in filtering window
The mean value of element is as output.The coefficient of its template window and mean filter difference, the coefficients of mean filter are all phases
Same is 1；And the coefficients of Gaussian filter, then the coefficient reduction with the increase at distance template center.So Gauss filters
Wave device is smaller to image fog-level compared to mean filter.
For example, generating one 5 × 5 gaussian filtering window, it is sampled using the center of template as coordinate origin.It will
The coordinate of each position of template brings Gaussian function into, and obtained value is exactly the coefficient of template.Again by the gaussian filtering window and figure
As convolution can be to image denoising.
Wherein, edge sharpening is for becoming more fully apparent fuzzy image.Generally there are two types of methods for image sharpening:
