Abstract
An interpolation apparatus that generates interpolation pixel values necessary for converting input video data of interlace scanning into video data of progressive scanning is provided. A plurality of candidate pixel-pairs each of which is composed of two pixels that are symmetric with respected to a pixel that is going to be interpolated are selected from pixels on adjacent two scan lines within one field of the input video data, and a difference between pixel values of each selected pixel-pair is calculated. A pixel-pair to be used for generating the interpolation pixel value is determined, based on the smallest difference and the second smallest difference of the calculated differences. An interpolation pixel value of the pixel that is going to be interpolated is generated based on pixel values of the determined pixel-pair.
