Appeal No. 2004-0252 Application No. 09/439,920 in th art, to remove the overlapping regions so that no abrupt transitions are represented thereby reducing the amount of high frequency coefficient data” (answer, paragraph bridging pages 8- 9). Further, the examiner mentions that while Igarashi does not teach removing the overlapping regions, Igarashi “does process the even fields separate from the odd fields in order to avoid the overlap” (answer, page 8). By the examiner’s own admission, Igarashi does not remove overlap regions, and, in fact, avoids the overlap. Yet, instant claim 26 indicates that an overlap region might exist and, if there is an overlapping region of two fields of the frame, any vertical detail, if present, is removed. Thus, the claim does not remove the overlap, but rather the vertical detail that might exist withing an overlapping region. Accordingly, the examiner’s reliance on column 7, lines 33-45, of Igarashi is not persuasive. However, at page 12 of the answer, the examiner further points to columns 29 and 30 of Igarashi where the reference does indicate that pairs of vertically adjacent rows are expected to be devoid of comb distortion (column 29, lines 31-33) and the examiner argues that comb distortion removal is shown in Igarashi’s Figure 2. The examiner also points out (answer, page 12) that Igarashi reduces vertical detail by eliminating high -14-Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
