The present invention relates to an image processing apparatus and method configured to be able to suppress increases in computation due to interpolation processing. For pixels of fractional pixel precision corresponding to sampling positions at a position b and a position d, pixel values corresponding to sampling positions at the position b and the position d are obtained by performing a sum-of-products operation using a first filter. For fractional pixel precision corresponding to sampling positions at a position c, pixel values corresponding to sampling positions at the position c are obtained by performing a sum-of-products operation using a second filter and an intermediate value B or an intermediate value D generated using a second filter with fewer taps than the first filter. The present invention may be applied to image coding apparatus that code in the H.264/AVC format, for example. |
