moving image displaying means for displaying the decoded moving image, wherein said moving image encoding means conducts the encoding on the basis of positional information said reduced moving image has to facilitate a change of said positional information in consideration with a case that a variation of said positional information occurs due to a disposition of said reduced moving image at the moving image combination, and said moving image composing means changes said positional information to positional information required for its combining processing when a need for the change of the positional information said reduced moving image has takes place.

Abstract
A moving image composing system for displaying reduced and encoded images at arbitrary positions on a multi-image raster. The moving image composing system comprises a moving image reducing unit for reducing a moving image inputted, a moving image encoding unit for encoding the reduced moving image to produce an encoded moving image, an accumulating unit for storing and accumulating the encoded image, and a moving image composing unit for combining more-than-one encoded moving images accumulated to produce a multi-image combined moving image. The moving image encoding unit performs the encoding processing to facilitate the change of positional information the reduced moving image has, in consideration with the case that the change of the position information occurs due to the disposition of the reduced moving image at its combination. When there is a need to change the positional information of the reduced moving image due to the combination processing, the moving image composing unit changes the positional information to positional information required for the combination processing.
