Abstract:
1. An image interpolation apparatus comprising: a data storage unit that is configured to store macro block data to be interpolated and peripheral macro block data used for interpolation; a half pel interpolation unit that is configured to receive data corresponding to one row of the data storage unit and to perform half pel interpolation thereof; a data selection unit that is configured to select a portion of a plurality of half pel interpolation results output from the half pel interpolation unit in response to data selection signals; and a quarter pel interpolation unit that is configured to generate the data selection signals in response to a motion vector of a decoded image and to perform quarter pel interpolation in response to the half pel interpolation results selected by the data selection unit; wherein the quarter pel interpolation is selectively performed in accordance with the motion vector, and wherein the data storage unit stores data of a size of (M+5)×(N+5) when a macro block has a size of M×N.
