ABSTRACT:
Provided is a method for magnifying an image by interpolation. The method including: a) setting m×m local windows and calculating a direction of each m×m local window; b) when a linear direction exists in an m×m local window, considering an edge exists; c) when a linear direction does not exist in the m×m local window, dividing the m×m local window into m/2×m/2 sub windows and calculating directions of the m/2×m/2 sub windows; d) when the directions of the m/2×m/2 sub windows exists toward the center of the m×m local window, considering a corner exists in the m×m local window; and e) selecting pixels located in a virtual line that goes along in the linear direction or in the directions to calculate a new pixel value by using the pixels.
