Abstract:
1. A method for processing motion information in an input interlace-scanned pixel signal, the method comprising the steps of: detecting motion information, as original motion information, indicating whether a target pixel is a moving picture or a still picture based on difference information of a pixel signal at the same location between two fields; storing the original motion information of a target pixel in a past field prior to a target field; distinguishing whether moving pixels of at least a predetermined number are present within an area containing a plurality of adjacent pixels containing a target pixel in the target field, each of the moving pixels being a pixel of which the original motion information indicates a moving picture; and outputting the original motion information of the target pixel in the target field when the distinguishing step distinguishes that the moving pixels of at least the predetermined number are not present within the area, and determined motion information of the target pixel in the target field, the determined motion information being determined based on the motion information of the target pixel in the target field and the motion information of the target pixel in the past field at the same location, when the distinguishing step distinguishes that the moving pixels of at least the predetermined number are present in the area.
