摘要 |
<p>A video encoding device performs motion-compensated inter-frame prediction corresponding to fractional pixel precision using a region-based adaptive interpolation filter (RBAIF) in which a frame is divided into regions and an IF coefficient is adaptively set for each division region, and includes means which constructs a linear simultaneous equation for obtaining an IF coefficient for a division region prescribed by a division position when an optimum division position is selected from among candidates for a prepared division position, and means which obtains the IF coefficient by solving the linear simultaneous equation, wherein the equation generation means diverts a redundant arithmetic processing result in an arithmetic operation of calculating the IF coefficient in a different division region and newly calculates only non-redundant difference information using the arithmetic operation.</p> |
