Claim 11:
12. The method of claim 8, wherein the first plurality of pixels (“px”) comprises pixels p0, p1, p2, p3, p4, and p5,
wherein the second plurality of pixels (“qx”) comprises pixels q0, q1, q2, q3, q4, and q5,
wherein the first reference value (“refP”), the second reference value (“refQ”), and the third reference value (“refMiddle”) are obtained as refP=(p5+p4+1)>>1, refQ=(q5+q4+1)>>1 and refMiddle=((p4+p3+2*(p2+p1+p0+q0+q1+q2)+q3+q4)+8)>>4 and wherein the filtered values are calculated as:

p(x)=(fInt(x)*refMiddle+(64−fInt(x))*refP+32)>>6; and

q(x)=(fInt(x)*refMiddle+(64−fInt(x))*refQ+32)>>6, and

wherein fInt(0) is equal to 58, fInt(1) is equal to 45, fInt(2) is equal to 32, fInt(3) is equal to 19 and fInt(4) is equal to 6, p(x) is a filtered version of px and q(x) is a filtered version of qx, where x ranges from 0 to 4.
