摘要： PROBLEM TO BE SOLVED: To provide a tampering detection apparatus and tampering detection method which perform high accuracy tampering detection even under relatively large deterioration of an image to be detected with respect to a source image. SOLUTION: A signal image for comparison corresponding to bits of watermark information extracted from image data D1 to be detected is generated, the watermark information being constituted of a bit stream in which values of bits are specified in accordance with a correlation between the signal image for comparison and a source image I, and the image data D1 to be detected being obtained by embedding the watermark information while superimposing it on the source image I. A correlation value between the image data D1 and each signal image for comparison is calculated, the bits of the watermark information is compared with the correlation value of the corresponding signal image for comparison. When the values of the bits of the signal image for comparison are not matched with the correlation between the signal image for comparison and the source image I, from these comparison results, absolute values of the correlation values are integrated, and on the basis of the integrated value, presence/absence of tampering for the image data D1 is determined.

摘要： PROBLEM TO BE SOLVED: To detect screen motion highly precisely with a small amount of operation.
SOLUTION: A decoder 101 decodes an encoded bit stream for outputting an encoding parameter and a decoded image. A statistics target block determination 102 calculates the degree of block complexity for each statistics block where the decoded image is divided into prescribed sizes, and for determining a statistics target block where each statistics block becomes the target of motion statistics processing for screen motion detection, based on the calculated degree of complexity in blocks and encoding parameters. A motion statistics processor 103 calculates the motion of an entire screen for outputting as a screen motion vector based on a motion vector included in the encoding parameters in the determined statistics target block.

摘要： PROBLEM TO BE SOLVED: To provide a media coder and a media decoder that can composite and reproduce a plurality of media signals without time deviations. SOLUTION: The media coder individually codes image signals in the unit of partial images A-D to generate an image coded stream, inserts a time stamp respectively in common to the image coded stream and frame numbers to the image coded stream, assembles the resulting image coded stream into packets, multiplexes the packets and provides an output of the result as partial image data. The media decoder demultiplexes and extracts the image coded stream from a plurality of the partial image data, decodes the stream, and corrects a time deviation between the decoded signals by referring to the frame number time stamp so as to match the time base among the divided image signals.
