| 发明名称 | Edge detection in a video field | ||
| 摘要 | A method for detecting edges in a video field, comprising the steps of: selecting edges for a pixel of the video field; determining sum of absolute differences (“SAD”) values for the selected edges; determining inverse SAD (“ISAD”) values for the selected edges; and detecting one or more certain ones of the selected edges as a valid edge as a function of the determined SAD values and the determined ISAD values. | ||

| 主权项 | 1. A method for detecting edges in a video field by a receiver, comprising the steps of: selecting edges for a pixel of the video field; determining sum of absolute differences (“SAD”) values for the selected edges; determining inverse SAD (“ISAD”) values for the selected edges; and detecting one or more certain ones of the selected edges as a valid edge as a function of the determined SAD values and the determined ISAD values, wherein the pixel of the video field is interpolated as a function of the detected one or more edges, and wherein the interpolated pixel and the video field are displayed by the receiver. | ||
