摘要： This invention relates to a coding method for motion-image data and others effective in a special interactive environment for transmitting motion-image data with information concentrated on only a partial region of a display image as in a two-way interactive system implementing real-time two-way interaction. The coding method involves dividing an image frame forming motion-image data into a plurality of rectangular regions, and grouping each of these rectangular regions into a preset ROI and a non-ROI. These rectangular regions are sequentially compressed so that a code length of a rectangular region grouped into the ROI is larger than a code length of a rectangular region grouped into the non-ROI, thereby generating coded data of each image frame.

摘要： A master key (K2,2) inputted by an input unit is stored in a storage unit. A matrix generating unit generates key element matrices (M1-M3) with respect to each of split keys (eR2, eR1, eR3) obtained by a key dividing unit dividing the master key (K2,2). To each coordinate entry of the key element matrices (M1-M3), operation data that successively obtained by repeating a hash operation with a one-way hash function is assigned, so as to maintain hierarchical nature of scalability (L). A key generating unit generates partial keys (K1,1-K2,2) corresponding to respective hierarchies of the scalabilities (R, L), on the basis of the key element matrices (M1-M3). These partial keys (K1,1-K2,2) are outputted to a coding unit or a decoding unit by an output unit.

摘要： The present invention relates to an encryption key generating method ensuring resistance to collusion attacks and achieving reduction in a key length of encryption keys corresponding to respective hierarchies of each scalability. In the encryption key generating method, an encryption key (K2,2) corresponding to data in the lowest hierarchies of hierarchical scalabilities (R, L) is divided as a master key by the number of hierarchies in scalability (R). Key element matrices (M1-M3) generated with respective split keys (eR2, eR1, eR3) are assigned operation data successively obtained by repeating a hash operation with a one-way hash function, so as to maintain hierarchical nature of scalability (L). Partial keys (K1,1-K2,2) corresponding to respective hierarchies of the scalabilities (R, L) are generated by combining key elements coordinately consistent among the key element matrices (M1-M3).

摘要： The present invention relates to an image processing method and image inspecting method with high versatility which enable efficient and highly accurate proof of authenticity of a digital image. The image processing method subjects at least a part of a digital image which can exist temporarily or continuously in a falsification-vulnerable environment, to a first morphology operation using a predetermined structuring element, to process the digital image. The image inspecting method subjects the digital image thus processed, to a second morphology operation using the same structuring element as in the first morphology operation. The morphology operations have the idempotent and the presence or absence of falsification can be detected by determining identity of images before and after the second morphology operation.

摘要： The present invention relates to a displaying method for video image coded data which prevents deterioration of image quality of a video image as much as possible, and conceals, from an observer, deteriorated video quality caused due to a transmission error. The displaying method selects target image frames to be decoded and target image frames to be discarded, by performing error determination (32) in parallel with an error recovery process and other image restoration processes, and decodes (33) only the selected target image frames. A predetermined display device sequentially displays (34) only the decoded target image frames while adjusting a frame rate.

摘要： The present invention relates to a moving-picture image data-distribution method that suppresses increases in processing loads at respective information terminals without being affected by an uneven distribution status of processing loads that changes over time or by a bandwidth status of a connected network. During a distribution operation of moving-picture image data from transmission-side information terminals (120, 130) to a reception-side information terminal (110), when the reception-side information terminal (110) repetitively issues a transmission requirement for moving-picture image data at a predetermined time interval to the transmission-side information terminals (120, 130), the reception-side information terminal (110) calculates, in advance, at least any one data amount of an own receivable amount of image frames and an own permissible load amount as reception-limit information, and subsequently sequentially notifies the transmission-side information terminals (120, 130) of an upper limit of at least any one of the data amount and a data structural element that is used as a basis for calculation of the data amount.
