According to an embodiment of the present invention, an interpolation method comprises: a step of calculating an interpolation error between pixels neighboring to a deficient pixel, in a low resolution image; a step of calculating autocorrelation with regard to each edge by using the interpolation error; a step of determining the direction with the lowest cost as an edge direction based on the calculation result; and a step of interpolating the pixel by using a weight value average filter. The present invention provides an edge-based interpolation method, configured to express a reliable edge detection method based on autocorrelation of neighboring pixels for candidate directions. |
