摘要 |
<p>A video encoding device includes means used to estimate a lower limit of a bit amount/distortion cost function when an adaptive interpolation filter (AIF) is used based on a generated bit amount and an encoding distortion amount when a region-based adaptive interpolation filter (RBAIF) is used upon selecting an optimum IF based on a bit amount/distortion cost function among a fixed interpolation filter (IF), the AIF, and the RBAIF, and means used to select an optimum IF based on a comparison of bit amount/distortion cost functions of the fixed IF and the RBAIF when the lower limit is a value greater than the bit amount/distortion cost function for the fixed IF, and selecting an optimum IF based on a comparison of bit amount/distortion functions of the fixed IF, the AIF, and the RBAIF only when the lower limit is less than or equal to the bit amount/distortion cost function for the fixed IF.</p> |
