The invention provides an image interpolating method, which comprises receiving the low resolution pixels Yij. Then, a homogenous area and an edge area of the image are determined according to pixel differences of the pixels Y2i,2j in comparing with a threshold. Then, the pixels Y2i,2j belonging to the...http://www.google.ca/patents/US7286721?utm_source=gb-gplus-sharePatent US7286721 - Fast edge-oriented image interpolation algorithm
