Abstract

The invention provides a de-interlace method and a de-interlace device. The de-interlace method is performed by the following process. First, edge directions of pixels surrounding a target pixel to be interpolated in an interpolating line are received, and a search range selected from the edge directions of the surrounding pixels is determined by checking a consistency of the edge directions of the surrounding pixels. Sequentially, an edge direction of the target pixel is determined based on the search range, and a pixel value of the target pixel is generated based on the edge direction of the target pixel for interpolation.

Description

De-interlacing method and device Technical field The present invention relates to a video image processing method and device, in particular to a de-interlace method and device. Background technique An interlaced video frame is divided into an odd field and an even field. The odd field is displayed on the odd line of the monitor, and then the even field is displayed on the even line of the monitor to present a complete frame. The de-interlacing method converts the interlaced video to the non-interlaced video to facilitate display in a sequential scanning mode with optimal quality. Figure 1 shows an odd field of an interlaced video containing odd lines of pixel data. The de-interlacing method generates even-line pixel data according to odd-line pixel data to form a complete frame. For example, the pixel value of the target pixel M0 of line 2 can be obtained by interpolation based on the adjacent pixel values ​​of line 1 and line 3. According to a known interpolation method, ...
