PURPOSE: A video encoding apparatus is provided to reduce the amount of data transmitted and received between a frame memory and an image encoding apparatus. CONSTITUTION: A coarse-grain motion estimation unit(110) performs coarse-grain motion estimation based on a current MB(Macro Block) and the SW(Search Window) regions of the current MB. A fine-grain motion estimation & motion compensation unit(111) performs fine-grain motion estimation and motion compensation based on the output of the coarse-grain motion estimation unit, a previous MB, the SW region of the previous MB, and the peripheral pixels of the SW region of the previous MB. Based on the previous MB, the fine-grain motion estimation and the output of the motion compensation unit, an encoding unit performs an encoding operation for an image. |
