A sub-pixel generating apparatus includes a first and a second calculating sections configured to execute an average value calculation for pixel values of a plurality of pixels in an image, with a round-up process and with a round-down process, respectively; and a selecting section configured to generate an interpolated pixel, by at least one selection process among a first selection process configured to select the round-up process or the round-down process depending on a position of the interpolated pixel, a second selection process configured to select the round-up process or the round-down process for each coding prediction method, and a third selection process configured to select the round-up process or the round-down process for each average value calculation if the interpolated pixel is obtained by a plurality of the average value calculations.
