Abstract
The invention discloses a kind of interlaced video scaling method of sampling is proposed, mainly comprises the steps that S1: to interlaced video de-interlacing, generating progressive video；S2: sampling is zoomed in and out to progressive video；S3: vertical filtering is increased to scaling sampled result；S4: to progressive video plus the generation interlaced video that interlocks.This method scaling sampling after video played on interleaved TV flicker problem be improved significantly, also ensure that the clarity of video will not be substantially reduced because of smothing filtering.
Description
Technical field
The present invention relates to video scaling fields more particularly to a kind of interlaced video to scale the method for sampling.
Background technique
In broadcast system, interlaced video scales the widespread demand having, such as the video file editor of non-volume, interlaced video
Broadcasting etc. is broadcasted, a kind of interlaced video scaling New sample method is needed, the scaling of video can be adjusted, and can guarantee video again
Result of broadcast.
Meanwhile most vision signals is partiting row sampling, using this scan format, can significantly be reduced
The bandwidth of video, but can also cause colour to be creeped, film flicker, edge blurry and phenomena such as sawtooth.Traditional video scaling skill
Art only simply does upper down conversion to interlaced video, and this defect is with regard to more obvious.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of interlaced video scaling method of sampling.
The invention mainly includes steps:
S1: to interlaced video de-interlacing, progressive video is generated:
S2: sampling is zoomed in and out to progressive video；
S3: vertical filtering is increased to scaling sampled result；
S4: to progressive video plus the generation interlaced video that interlocks.
Further, after the step S1 is to interlaced video de-interlacing, the progressive video of 2 times of length is generated.
Further, the step S2 zooms in and out sampling using lancos to each picture of progressive video.
The beneficial effects of the present invention are: the video after this method scaling sampling plays flashing on interleaved TV
Problem be improved significantly, also ensure that the clarity of video will not be substantially reduced because of smothing filtering.
Detailed description of the invention
Fig. 1 is interlaced video scaling method of sampling flow chart.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing with tool to this
Invention is described in further detail.
As shown in Figure 1, the present invention proposes a kind of interlaced video scaling method of sampling, mainly comprise the steps that
S1: to interlaced video de-interlacing, progressive video is generated:
S2: sampling is zoomed in and out to progressive video；
S3: vertical filtering is increased to scaling sampled result；
S4: to progressive video plus the generation interlaced video that interlocks.
Further, after the step S1 is to interlaced video de-interlacing, the progressive video of 2 times of length is generated.
Further, the step S2 zooms in and out sampling using lancos to each picture of progressive video.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
Claims (3)
1. a kind of interlaced video scales the method for sampling, which comprises the following steps:
S1: to interlaced video de-interlacing, progressive video is generated；
