Problems solved by technology

[0003] At the same time, most of the video signals are interlaced sampling. Using this scanning format can greatly reduce the bandwidth of the video, but it will also cause color crawling, picture flickering, blurred edges and jagged edges.
The traditional video scaling technology simply performs up-and-down conversion for interlaced video, and this defect is even more obvious

Embodiment Construction

[0014] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and tools.

[0015] Such as figure 1 As shown, the present invention proposes a kind of interlaced video scaling sampling method, mainly comprises the following steps:

[0016] S1: Deinterlace interlaced video to generate progressive video:

[0017] S2: Scale and sample the progressive video;

[0018] S3: Add vertical filtering to the zoomed sampling result;

[0019] S4: Add interlacing to progressive video to generate interlaced video.

[0020] Further, after de-interlacing the interlaced video in the step S1, a progressive video of twice the length is generated.

[0021] Further, the step S2 uses lancos to zoom and sample each picture of the progressive video.

[0022] The above disclosures are only preferred embodiments of the present invent...

Abstract

The invention provides an interlacing video scaling sampling method. The method mainly includes the following steps: S1, carrying out de-interleaving on an interlacing video to generate a row-by-row video; S2, carrying out scaling sampling on the row-by-row video; S3, adding vertical filtering to a scaling sampling result; and S4, carrying out interleaving adding on the row-by-row video to generate an interlacing video. The playing flickering problem of the video after scaling sampling of the method on an interlacing scanning television is significantly alleviated, and an effect that definition of the video cannot be significantly reduced due to smoothing filtering is also guaranteed.

Description

technical field [0001] The invention relates to the field of video scaling, in particular to an interlaced video scaling and sampling method. Background technique [0002] In the broadcast system, interlaced video scaling has a wide range of needs, such as non-edited video file editing, interlaced video playback, etc., a new method of interlaced video scaling and sampling is needed, which can adjust the scaling of the video and ensure the accuracy of the video. Play effects. [0003] At the same time, most of the video signals are interlaced sampling. Using this scanning format can greatly reduce the video bandwidth, but it will also cause color crawling, picture flickering, blurred edges and jagged edges. The traditional video scaling technology simply performs up-down conversion on interlaced video, and this defect is even more obvious. Contents of the invention [0004] In order to solve the above problems, the present invention proposes an interlaced video scaling an...
