Abstract:
1. An interlaced image processing method for processing fields generated by interlacing, the fields including a plurality of rows of scan signals, said interlaced image processing method comprising the following steps: performing horizontal line detection on a current field so as to find which of the rows of the scan signals is a horizontal line, wherein, in performing the horizontal line detection, a specific determination is made with respect to each pixel of a scan signal, the specific determination comprising a determination as to whether a current pixel satisfies at least one specific condition; according to the horizontal line detection result of the current field and a horizontal line detection result of a previous field, adjusting position of the horizontal line in the current field so as to approach position of a corresponding horizontal line in the previous field, wherein when adjusting the position of the horizontal line, the rows of the scan signals that are not horizontal lines are shifted upward when the current field is a top field; and according to the result of position adjustment, re-sampling the current field.
