Abstract:
A system which utilizes the processing capabilities of the graphics processing unit (GPU) in the graphics controller. Each interlaced video field is resampled to provide full resolution and then displayed at full rate. The field pixel values are resampled as appropriate using the GPU to provide values corresponding to the locations missing from that field. The resampled values and the original values are provided to the frame buffer for final display for each field. Each of these operations is done in real time for each field of the video. Because each field has had the values resampled to provide a value for the missing locations from the other field, the final displayed image is both full resolution and full rate. In an alternate embodiment, the values of the preceding and following fields are included in the resampling operation to improve still object rendition.
