摘要： PROBLEM TO BE SOLVED: To provide a technology for properly switching and reproducing moving image data picked up in different frame rates.
SOLUTION: A normal frame rate stream-decoding part 68 decodes a stream of a normal frame rate and outputs a frame for a moving image of a normal frame rate. A high frame rate stream-decoding part 72 decodes a stream of a frame rate higher than a normal one about at least a partial scene included in the stream of the normal frame rate and outputs a frame of a moving image of a frame rate higher than the normal one. When changing a frame rate of a moving image that is currently reproduced, a frame selecting part 62 reproduces the frame rate of a stream of the moving image to be reproduced before and after switching, while performing the gradual switching from a frame rate before the switching to a frame rate after the switching.

摘要： PROBLEM TO BE SOLVED: To provide a technique for efficiently managing a plurality of moving image data picked up at different frame rates.
SOLUTION: A frame buffer 16 stores frames of a moving image picked up at a higher frame rate than usual. A frame thinning-out unit 18 thins out the frames in the frame buffer at predetermined intervals to generate frames of a normal frame rate. A normal frame rate frame encoding unit 36 encodes the thinned-out frames to generate a stream of the normal frame rate. A high frame rate frame encoding unit 38 encodes the frames stored in the frame buffer to generate a stream of a high frame rate only in a predetermined period in parallel with the stream generation of the normal frame rate. A control unit 22 generates related information specifying the predetermined period. A file connection unit 32 connects the stream of the normal frame rate, the stream of the high frame rate, and the related information together to generate a single file.

摘要： PROBLEM TO BE SOLVED: To provide an encoding technology capable of solving a problem of an increase in a coding amount caused by information for particularizing scan sequence added to coded data in scanning DCT blocks to apply variable length encoding to an image.
SOLUTION: An image reduction section 12 reduces an input image to give the result to a basic layer processing block 120. A prediction section 24b applies in-frame prediction to an image frame and gives an in-frame prediction error image to a DCT section 26b. The DCT section 26b applies discrete cosine transform (DCT) to the in-frame prediction error image and gives an obtained DCT coefficient to a quantization section 28b. The quantization section 28b quantizes the DCT coefficient and gives the result to a variable length coding section 30b. The variable length coding section 30b uniquely determines a scan sequence being one of ordinary zigzag scan, horizontal priority scan, and vertical priority sequence on the basis of an aspect scaling ratio of the image to scan the DCT coefficient in the scan sequence determined in the DCT block thereby applying the variable length encoding to the image.

摘要： PROBLEM TO BE SOLVED: To provide an encoding technology of solving a problem of a degraded encoding efficiency caused by an increase in an encoding amount in applying interactive ROI encoding to moving pictures.
SOLUTION: A ROI setting section 14 establishes interactive ROI regions on a moving picture frame. An image division section 10 divides whole regions of the moving picture frame into the interactive ROI regions and non-interactive ROI regions other than the interactive ROI regions. An image reduction section 12 reduces the interactive ROI regions and the non-interactive ROI regions to respectively convert them into low resolution images and gives the result to a basic layer processing block 120. The basic layer processing block 120 and an extended layer processing block 110 independently encode the interactive ROI regions with low and high resolutions by the unit of a slice to produce hierarchical encoded data with spatial scalability. On the other hand, only the basic layer processing block 120 encodes the non-interactive ROI regions to produce encoded data without the spatial scalability.
