Contrast increases and saturation degree increases etc..
Specifically, the video resource file that electronic equipment is shown is to pass through decoded picture material, due to by decoding
Picture material later is that the data of RGBA format need the data by RGBA format to be converted to optimize to picture material
HSV format specifically obtains the histogram of picture material, obtains statistics with histogram by the data conversion of RGBA format
For the parameter of HSV format, the data of RGBA format are being converted to by 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:
One is the differential methods, another is high-pass filtering method.
Wherein, contrast increases the image quality for enhancing image, so that the color in image is distincter, it is specifically, right
Than a kind of method that degree stretching is image enhancement, greyscale transformation operation is also belonged to.By greyscale transformation, gray value is stretched to whole
The section of a 0-255, then what its contrast clearly substantially enhanced.It can be with following formula by the gray scale of some pixel
Value is mapped to bigger gray space:
I (x, y)=[(I (x, y)-Imin)/(Imax-Imin)] (MAX-MIN)+MIN；
Wherein Imin, Imax are the minimum gradation value and maximum gradation value of original image, and MIN and MAX will be stretched to
The minimum gray value and maximum value of gray space.
Therefore, in the present embodiment, after the current distance of the display screen and user that determine electronic equipment, can based on away from
From and the corresponding relationships of Optimal Parameters determine corresponding with current distance Optimal Parameters, and as objective optimization parameter,
It should be understood that objective optimization parameter may include an Optimal Parameters, it also may include multiple Optimal Parameters, do not limit herein
It is fixed.
