摘要： After a digital content is loaded into an information terminal such as a PC, ID information unique to a viewer or a user of the PC is imprinted into the content. The ID information is imprinted into a predetermined location of the content or alternatively, it may be imprinted over the entire content in the form of a spatial frequency. The content with an ID added thereto is then enabled to be used in the terminal.

摘要： In an image generating system or apparatus, a first storage unit stores key frames and corresponding point data therefor. A performance specifying unit determines a processing performance of a user terminal. A resolution decision unit determines a resolution of motion pictures (intermediate frames) to be generated or reproduced in accordance with the determined processing performance. An intermediate frame generator generates intermediate frames at the determined resolution by interpolating the key frames based on the corresponding point data.

摘要： When a moving picture is encoded with a high compression ratio by the MPEG, the block noise becomes remarkable. Matching is calculated between the first and the second key frame and corresponding point information is generated. According to this corresponding point information, a virtual second key frame is generated. A difference between the actual second key frame and the virtual second key frame is compressed/encoded by a difference encoder. The first key frame, the corresponding point information, and the compressed/encoded difference are outputted as encoded data between the first and second key frame.

摘要： An image interpolation method and apparatus by which to quickly generate and display motion pictures using a small amount of data. An image input unit inputs a first image and a second image. A matching processor computes a pixel matching between those images so that a corresponding point is obtained on the second image with respect to a lattice point of a mesh on the first image. The matching processor stores the matching results recorded as a corresponding point file. An intermediate image generator generates an intermediate image between the first image and the second image based on the corresponding point file. In particular, in generating the intermediate image, an attribute of the pixels on one image may be used as such without the attribute being interpolated between pixels of each image. Thus, when generating intermediate images, only one image and a smaller corresponding point file can be used.

摘要： An image coding and decoding technology for digital movie or video that provides for error checking within the digital video files. The digital video is coded in a data stream that includes key frames and correspondence data between key frames as well as additional correspondence data between somewhat separated key frames. During decoding, an intermediate image generator generates an intermediate frame or frames by interpolation, based on key frame data and correspondence data file between key frames. If an error detector detects an error in an input coded data stream, an error controller instructs the intermediate image generator to perform an error avoidance processing which may include substituting another key frame for an error-containing key frame or use of the additional correspondence data to create the intermediate key frame or frames for an error-containing correspondence data file, and so forth.

摘要： An image coding and decoding technology for compressing motion pictures which makes use of critical point filter technology and that includes detection of scene changes to provide more accurate decoding. An image input unit acquires key frames. A scene change detector detects when there is a scene change between key frames, and notifies a matching processor to that effect. The matching processor then skips generation of correspondence data between those key frames. A stream generator generates a coded data stream in a manner that key frames and associated correspondence data are incorporated when there is no scene change, while key frames and associated correspondence disable data are incorporated when there is a scene change. This allows a decoder to more accurately decode the data stream and take account of scene changes.

摘要： An image processing method and apparatus for encoding and decoding image data in which the coding and decoding method may be simplified based on factors such as processing speed requirements. In encoding, an image input unit receives a first image and a second image (key frames). A matching processor begins performing a multiresolutional analysis using pixel-by-pixel matching between the images but, due to predetermined factors or settings, either discontinues the analysis or switches to a simplified method of analysis prior to the final resolution level. If the analysis is discontinued during encoding (i.e. at the encoding side), the analysis may be completed at the decoding side prior to conducting the decoding and the decoding side may be arranged accordingly.

摘要： An image input unit acquires a first image and a second image. A matching processor computes a pixel matching between the images so that corresponding points are obtained on the second image with respect to lattice points of a mesh defined on the first image. A result thereof is recorded as a corresponding point file. An intermediate image generator generates an intermediate image of the first image and the second image based on the corresponding point file. Since the corresponding point file is composed of corresponding lattice points alone rather than corresponding pixels or the like, the amount of data is relatively small, and thereby allows efficient implementation of and application to various image effects, motion picture compression, on-line commodity presentation, and mobile applications.
