Abstract:
A video image coding device having a first coding mode for encoding an image within a first region and a second coding mode for encoding an image within a second region being a partial region of the first region, which comprises:a region selecting portion for selecting the first region and the second region, a shape coding portion for encoding shapes of the first and second regions, a video image coding portion for encoding only values of pixels inside a selected region according to an output of the shape coding portion, a flag generating portion for generating overlapping information indicative of whether (a) a partial regional image data coded in the second coding mode is overlapped with a background image generated by an image coded in the first coding mode or (b) a partial regional image data coded in the second coding mode is overlapped with a background image generated by any method, and a coding data integrating portion for integrating the outputs of the shape coding portion, the video image coding portion and flag generating portion.
