Directional interpolation method using frequency information and related device
A method for interpolating a pixel within an image is provided. The image has a plurality of pixels arranged in a matrix format. The method includes: detecting if there is an edge in a block of the image according to frequency information of the block associated with the pixel; determining an interpolation direction for the pixel according to the detection result and the frequency information; and interpolating the pixel according to the determined interpolation direction. Additionally, a device for implementing the method is also provided.
