METHOD AND DEVICE FOR INTERPOLATING IMAGES BY USING A SMOOTHING INTERPOLATION FILTER.

摘要

Provided is a method for interpolating images by determining an interpolation filter coefficient. An image interpolation method is disclosed that takes into account smoothing for generating the pixel value of at least one subpixel unit, in which method: an interpolation filter is selected from among interpolation filters for generating the pixel value(s) of at least one subpixel unit positioned between pixel units, the selection being performed in a fashion which differs based on the interpolation position and smoothness of the subpixel unit(s); and the selected interpolation filter is used in order to interpolate pixel values of pixel-unit pixels.
