Abstract: A multi-point interpolation apparatus for reading out plural picture data from a picture memory and effecting interpolation includes apparatus that writes luminance data and chroma data of pixel data at (n+1) point pixel positions at the same address of a picture memory, and reads out luminance data and chroma data from the picture memory. The apparatus also selects, from the luminance data and chroma data of the pixel data at the read-out (n+1) point pixel positions, the luminance data and the chroma data at the n-point pixel positions, while generating, from the luminance data and the chroma data at the selected n-point pixel positions, the luminance data and the chroma data at the designated interpolating point by n-point interpolation.
