Abstract
Interpolation method and apparatus for interpolating pixels using levels of pixels surrounding a pixel to be interpolated is disclosed wherein PA1 a level difference between two pixels on an interpolation line is calculated for all interpolation lines, likelihoods of correlation are calculated from the level differences obtained using a membership function, PA1 an interpolation direction is determined based on the likelihoods of correlation and directions of the interpolation lines and an interpolation value for the pixel to be interpolated is calculated based on levels of two pixels on the interpolation line having the interpolation direction determined.
