摘要： A film supply apparatus is provided wherein one film is held in a waiting position while a first film is being processed and the waiting film is automatically processed after the processing of the first film has been completed. The apparatus comprises a film holding supply mechanism with a film nip section that nips the film at a film waiting position, a film moving mechanism for moving the film from the film waiting position to a film supply position and a driving mechanism for nipping and transferring the film between it and the film moving mechanism. The film moving mechanism is configured to return to the film waiting position after a predetermined portion of the first film has been transferred and wherein after the film moving mechanism has returned to the film waiting position, the next film can be nipped using the film nip section at the film waiting position.

摘要： The encoding computational complexity and the decoding computational complexity are reduced while suppressing deterioration of coding efficiency in comparison with conventional intra divided-picture coding. A divided picture generation unit divides an input encoding target picture into blocks having the same size, and collects pixels having the same relative position in the blocks to generate divided pictures having the same size. An intra divided-picture encoding unit performs intra divided-picture encoding on some divided pictures. A reference picture selection unit selects, as a reference picture, an encoded divided picture in which a pixel position on an original picture is close in order to encode the other encoding target divided pictures. An inter divided-picture predictive encoding unit generates a predicted picture using the selected reference picture and encodes an encoding target divided picture through inter divided-picture prediction in units of divided pictures.

摘要： In motion vector prediction encoding, the efficiency of motion vector prediction is improved and the efficiency of moving picture encoding is improved. A motion search is performed for a block to be encoded in a picture to be encoded using an encoded reference picture to calculate a motion vector. A plurality of blocks which include at least one of encoded blocks in the picture to be encoded and encoded blocks in an encoded picture and in predetermined positions relative to the position of the block to be encoded in the picture to be encoded are set as primary candidate blocks, and N primary candidate reference motion vectors are determined from motion vectors used in encoding the primary candidate blocks. The degrees of reliability of the primary candidate reference motion vectors which quantitatively represent effectiveness in motion vector prediction of the block to be encoded is calculated using encoded picture information for each of the primary candidate reference motion vectors. Top M primary candidate reference motion vectors with higher degrees of reliability are selected from the primary candidate reference motion vectors as secondary candidate reference motion vectors. A predictive motion vector of the block to be encoded is calculated using the secondary candidate reference motion vectors, and a residual between the motion vector obtained through the motion search of the block to be encoded and the predictive motion vector is encoded as encoded information of the motion vector.
