BACKGROUND
The invention relates to motion vector detecting in an MPEG (Motion Picture
Experts Group) system. Claim 1 is reproduced below.
1. An adaptive motion vector detecting apparatus for adaptively selecting
pixels employed to detect motion vectors between a first video frame and a second
video frame, said first video frame including a reference block of pixels comprised
of all of the pixels in an M x N block of said first video frame and said second video
frame including a check block of pixels, comprising:
analyzing means for adaptively determining positions of a first subset of
pixels in said reference block from a variable feature of said reference block; and
selecting means for sampling said first subset of pixels in said reference
block and a second subset of pixels in said check block at said positions
determined by said analyzing means.
The examiner relies on the following references:
Yamada et al. (Yamada) 5,475,446 Dec. 12, 1995
Kondo 5,612,751 Mar. 18, 1997
(filed Jan. 30, 1995)
Claims 1-3, 8, 19-21, and 26 stand rejected under 35 U.S.C. § 102 as being
anticipated by Yamada.
Claims 4-7, 9-18, 22-25, and 27-36 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Yamada and Kondo.
We refer to the Final Rejection (Paper No. 8) and the Examiner's Answer (Paper
