Embodiment Construction

[0035] The method based on the invention provides a hybrid two-dimensional and three-dimensional interlaced progressive conversion method for generating accurate progressive video display signals from interlaced video signals. The data in the interlaced video field stream is interpolated by applying the current field data (i.e. the data in the field where the pixel to be interpolated is located) and the front and rear field data (i.e. the data in the video field different from the current field) to each line in the current field. Each field is converted into an image frame. The "hybrid" interpolation method can effectively reduce the defects caused by the traditional two-dimensional interlaced progressive conversion method for static scenes.

[0036] Figure 3A Four consecutive interlaced video fields 600(T-1), 600(T), 600(T+1) and 600(T+2) are shown. Each field contains twenty pixels arranged in five columns and four rows C1, C2, C3, C4 and C5. Even fields 600(T-1) and 600...

Abstract

An interpolation-based interlaced-to-progressive conversion method is used to generate progressive video frames from multi-field data from an interlaced video signal. A pixel on the top of the pixel to be interpolated and a pixel below it, a pixel corresponding to the same position in the previous field where the pixel to be interpolated is located, and a pixel corresponding to the same position in the next field where the pixel to be interpolated is located (that is, the pixel to be interpolated Two pixels whose positions are the same as the pixel to be interpolated in the current field in the previous field and the next field of the field) can be used to generate the pixel value of the pixel to be interpolated by using an interpolation method. Utilizing pixel data in multiple fields increases the resolution of the interpolation operation results, thereby improving the accuracy of output progressive video frames. The pixel values ​​of neighboring pixels of the pixel to be interpolated may also be adjusted to improve the consistency of the video display of the output video frame.

Description

technical field [0001] This invention relates to digital display systems. More precisely, the present invention relates to a method and circuit implementation for accurate interlaced-to-progressive conversion of video signals. Background technique [0002] Typically a modern video signal consists of a series of still images called "frames". Playing this sequence of image frames in rapid succession, such as on a computer display or television, produces the effect of continuous motion in the image content. For example, the specified playback rate of a standard NTSC (National Television System Committee) television signal is 29.970 frames per second. For some historical reasons, the video signal frames in most consumer video applications (and many professional video applications) are composed of interlaced signals, which are composed of a series of image "fields". Each field contains half of a frame of video signal. Specifically, one field includes the signals of every othe...
