Abstract (in Japanese) (See Japanese page) 
(in English) We are developing an efficient lossless video coding scheme based on motion compensation and block-adaptive 3D prediction. In this scheme, multiple 3D predictors which use both the current and motion-compensated previous frames are switched block-by-block.In the previous work, these predictors are designed for each frame. However, if textures and/or motions in a sequence vary spatially rather than temporally, designing the predictors for each area given by intra-frame dividing and inter-frame merging would be reasonable .In this paper, therefore, appropriate conditions for such spatial-temporal partitioning are explored. Simulation result indicate that the proposed method can provide bit-rate savings of 0.01--0.06 bits/pel for tested images.
