Problems solved by technology

[0009] The present invention provides a video de-interlacing method and device. Before processing the interlaced video, it firstly determines and analyzes various application scenarios existing in the video, and uses corresponding de-interlacing methods for different scenarios to solve the problem of the prior art. The problem that the output video quality deteriorates when de-interlacing is performed indiscriminately for different application scenarios

Embodiment Construction

[0031] In order to solve the problem in the prior art that the quality of the output video is degraded when de-interlacing processing is performed on different application scenarios without distinction, the present invention provides a video de-interlacing method and device.

[0032] The implementation principle of the video deinterlacing method provided by the embodiment of the present invention is: read the video frames contained in the input video stream frame by frame, respectively identify the static area and the scrolling subtitle area in the read video frame, and target the identified static area The deinterlacing process is performed on the area, the rolling subtitle area and the motion area respectively, wherein the motion area includes areas in the video frame other than the static area and the rolling subtitle area. According to the video deinterlacing method provided by the embodiment of the present invention, the scene deinterlacing process is performed on the vide...

Abstract

The invention discloses a video deinterlacing method and device used for solving a problem of output video quality degradation due to indiscriminate deinterlacing treatment for different application scenes in the prior art. The video deinterlacing method includes reading video frames contained in an input video flow frame by frame and recognizing and reading static areas and roll title areas in the read video frames separately; performing deinterlacing treatment on the recognized static areas, the roll title areas and motion areas separately, wherein the motion areas include areas in the videoframes except the static areas and the roll title areas.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video deinterlacing method and device. Background technique [0002] De-interlacing technology is a video format conversion technology that processes interlaced scanning video into a video format that can be played on non-TV terminals. TV video signals are collected and sent in an interlaced scan mode, which divides video frames into odd and even fields. When the TV or set-top box receives it, it will process the two scenes in sequence and then display them. Each video picture is actually an image that has been disassembled. However, when non-television terminals (such as digital video displays such as liquid crystals and plasmas) receive, due to processing and displaying according to image frames, various problems caused by field effects such as flickering, sawtooth, and feathering will appear on the screen. The purpose of de-interlacing technology is to eli...
