Claim Text:
1. An apparatus for high speed filtering of an image for high precision, the apparatus comprising: a coordinate determining unit configured to determine coordinates (P,Q) of a first pixel on an edge of an image displayed on a screen; a pixel determining unit configured to determine second pixels with coordinates from (P,Q1) to (P,Qu) and coordinates from (P1,Q) to (Pv,Q), in response to the direction of the edge being in a direction other than parallel to the axial direction of P and the axial direction of Q, where u of Qu corresponds to a number of pixels located on a vertical side of the screen and v of Pv corresponds to a number of pixels located on a horizontal side of the screen, and, to determine the second pixel with coordinates including either P+m or Q+m in response to the direction of the edge being in a direction other than parallel to the axial direction of P and the axial direction of Q, m being an integer; and a processing unit configured to compare a first block including the first pixel and a second block including the second pixels, to calculate a weight with respect to the second block based on the comparison, and to filter the first pixel by adjusting a brightness value of the first pixel using a value obtained by multiplying a brightness value of the second pixels and the weight.
