Title: Moving picture encoding apparatus

Abstract: Disclosed is a moving picture encoding apparatus which comprises: means for dividing moving picture data picked up by a camera into small blocks and detecting motion vectors corresponding to the small blocks; encoding means for motion-compensating the small blocks based on the motion vectors to perform an inter-frame predictive encoding process; means for extracting a moving object area based on the motion vectors; means for calculating a horizontal and vertical components of a representative vector of the moving object area based on the motion vectors of all or a part of the moving object area; means for setting pan/tilt amounts based on the horizontal component and the vertical component of the representative vector; means for outputting a signal that represents the pan/tilt amounts; and means for causing the encoding means to finely perform quantization only for the small block in the moving object area.
