Embodiment Construction
[0059] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0060]see Figure 1 to Figure 3 , this embodiment provides a video deinterleaving processing method, and the method of the present invention may be applied to a video deinterleaving processing device. The de-interlacing process is actually to process the video signal collected by field image, and restore the frame image signal of each field image time slice, that is, to reconstruct the missing complementary field image on each field image time slice to obtain a complete frame image. When performing de-interleaving processing, to obtain the image data of the previous line and the next line of pixels that need to be reconstructed in the frame image space (that is, the data on the known field image at the current time), use the previous...

The invention discloses a video de-interleaving method and device. The method comprises the following steps: space weight coefficients and time weight coefficients of all pixels of a picture of a field which needs to be rebuilt at current time are calculated, and static state weighting coefficients of all pixels of the picture of the field which needs to be rebuilt are calculated according to the space weight coefficients and the time weight coefficients of all pixels of the picture of the field which needs to be rebuilt; picture data of the field which needs to be rebuilt can be calculated according to the static state weighting coefficients of all pixels of the picture of the field which needs to be rebuilt, spatial interpolation data of the picture of the current field which needs to be rebuilt and time interpolation data of the picture of the current field which needs to be rebuilt; based on a technical solution disclosed in the invention, by considering time weight and spatial weight, the weighting coefficients are obtained and then subjected to interpolation operation, and therefore the picture data of the rebuilt field can be obtained. Image quality can be improved, and video de-interleaving effects can be enhanced.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to a motion video deinterlacing processing method and device. Background technique [0002] There are two scanning modes in the current broadcast television system: one is progressive scanning (Progressivescanning) mode, and the other is interlaced scanning (Interlacedscanning) mode. Progressive scanning is to scan a complete image within each Δt time, which is called a frame. Interlaced scanning is to divide a frame of image into two fields for 2:1 interlaced scanning. The first field is called an odd field, and only its odd lines are scanned; the second field is called an even field, and only its even lines are scanned. The advantages of progressive scanning are high image definition, fine and rich image details, stability and no flicker between lines, etc.; the disadvantage is that it requires a large transmission bandwidth. The advantage of interlaced scannin...
