1. A method of reducing interlaced noise on an interlaced video display device by reducing motion artifacts due to motion that occurs between acquisition of fields of video that comprise a video frame, comprising the steps of:

  • a) comparing at least one pixel in at least one line of a first field of video with at least one pixel in at least one line of a second field of video that is interlaced with said first field on said video display device, said at least one line of said first field being in close proximity to said at least one line of said second field, said at least one pixel in said first field being in close proximity to said at least one pixel in said second field,b) determining whether a difference between a value of said at least one pixel in said at least one line of said first field and a value of said at least one pixel in said at least one line of said second field exceeds a fixed value,c) if said difference between said values of said pixels exceeds said fixed value, replacing said value of said at least one pixel in said at least one line of said second field with a value closer to said value of said at least one pixel in said at least one line of said first field,d) if said difference between said values of said pixels is less than said fixed value, maintaining said value of said at least one pixel in said at least one line of said second field,e) performing steps a) through d) above for additional pixels in said at least one line of said first field and said at least one line of said second field, andf) preforming steps a) through e) above for additional lines of said first and second fields.
