Grade, class parameter C indicate the tertiary gradient.A, b and c respectively indicates different enhancing processing modes.If then receiving target
Grade is the first estate, then class parameter A can be searched from mapping table.When finding class parameter A, then to search this right
Answering the corresponding enhancing processing mode of A in relation table is a, the corresponding enhancing processing side of goal gradient so as to get selection
Formula is a.
After determining the corresponding enhancing processing mode of goal gradient, then the corresponding image of enhancing processing mode can be determined
Processing Algorithm.Optionally, can be, the corresponding mode parameter of every kind of enhancing processing mode, which parameter it is corresponding one or
Polyalgorithm identification parameters, each algorithm identification parameters indicate an image processing algorithm.Then after determining enhancing processing mode,
Can the corresponding algorithm parameter of parameter by this way, call the corresponding image processing algorithm of enhancing processing mode.Optionally,
Image processing algorithm corresponding to every kind of enhancing processing mode, can also be encapsulated as a program module.Determine enhancing processing side
After formula, the corresponding program module of enhancing processing mode is called.
For the video of different resolution, have the characteristics that different.For example, being differentiated for SD and smooth video
Rate is lower, and noise is serious in video, and image is fuzzy in video frame, and image border is unintelligible, has edge noise.And for high definition
Etc. high-resolution video, noise is small, image clearly.Due to the low video of the video and resolution ratio of high resolution, video frame
Middle feature of image is different, for the video of different resolution, the video source modeling of same grade, if all being handled using identical enhancing
Mode is handled, then the image quality that may handle rear video is entirely different, and may reinforcing effect to video it is undesirable.Example
Such as, sharpening can make the image of high definition apparent, but sharpening and denoising contradict, in the video of low resolution, if carrying out
Edge contrast may be exaggerated edge noise instead.Therefore, it for the video of different resolution, to be realized by enhancing identical
Or similar video image quality, different image processing algorithms is needed, corresponding, the video of different resolution enhances processing side
Formula.
Optionally, in the embodiment of the present application, the different resolution of can be according to different resolution the characteristics of, corresponding video are set
Set different mapping tables.In different mapping tables, the corresponding enhancing processing mode of identical class parameter is different.?
With regard to saying, different enhancing processing modes can be chosen if the resolution ratio of video is different for the video source modeling of same grade.
Specifically, electronic equipment can obtain the resolution ratio of video according to video data.Wherein, the resolution ratio of video is to use
A how many parameter of data volume, can be indicated, wherein W refers to video frame in cross by way of W*H in measurement video frame
Upward valid pixel, H refer to the valid pixel of video frame in the longitudinal direction.
The mode for obtaining the resolution ratio of video can be, and electronic equipment is decoded video, video counts after the decoding
In, there is the data portion of corresponding storage resolution, which can be one piece of data.It therefore, can be from video
In decoded data, the corresponding data portion of resolution ratio is got, then obtain video from the corresponding data portion of resolution ratio
Resolution ratio.
For example, H.264, while being also MPEG-4 Part X, it is by ITU-T Video Coding Experts Group (VCEG) and ISO/
The height pressure that the joint video team (JVT, Joint Video Team) that IEC dynamic image expert group (MPEG) constitutes jointly proposes
Contracting digital video coding-coding device standard.It include the resolution of video for using the code stream H.264 encoded, in the stream information of code stream
Rate, and the stream information of code stream is stored in special structure, is called SPS (Sequence Parameter Set), which is
For the corresponding data portion of decoded data intermediate-resolution.According to the format information of H.264 code stream, in H.264 code stream, with
0x000x00 0x01 or 0x00 0x00 0x00 0x01 are opening code, therefore pass through first character section after detection opening code
Whether five be 7 (00111) to judge whether it is SPS afterwards.After acquisition SPS, so that it may parse the resolution ratio of video.Its
In, there are two member, pic_width_in_mbs_minus1 and pic_height_in_map_units_minus_1 in SPS,
Respectively indicate the width and height of image, and be all subtract 1 again (as unit of on area by the block of 16*16) as unit of 16, so
Actual width is (pic_width_in_mbs_minus1+1) * 16, a height of (pic_height_in_map_units_minus_1
+ 1) * 16, that is, corresponding to W in above-mentioned resolution ratio is (pic_width_in_mbs_minus1+1) * 16, in corresponding above-mentioned resolution ratio
H is (pic_height_in_map_units_minus_1+1) * 16.
After getting the resolution ratio of video, the corresponding mapping table of the resolution ratio can be determined, with determining correspondence
Relation table is as the mapping table for searching class parameter.That is to say, being looked into the corresponding mapping table of resolution ratio of video
