Patent ID: 7983530

Claim:
A recording and playback apparatus for recording an image on a recording medium and playing back the image from the recording medium, the recording and playback apparatus comprising: first obtaining means for obtaining one or more moving parameters regarding motion from a high definition (HD) image; converting means for converting the first image into a decimated image composed of a lesser amount of data than the HD image by frame decimating the HD image; second obtaining means for obtaining one or more moving parameters from the decimated image; and difference information obtaining means for obtaining difference information regarding one or more differences between the moving parameters of the HD image and the moving parameters of the decimated image; compressing means for compressing the decimated image into compressed data using the moving parameters obtained from the decimated image; multiplexing means for multiplexing the compressed data and the difference information into multiplexed information; and recording controlling means for recording the multiplexed information on the recording medium; reading controlling means for reading the multiplexed information from the recording medium; demultiplexing means for demultiplexing the multiplexed information into the compressed data and the difference information; decompressing means for decompressing the compressed data into the decimated image and the moving parameters obtained from the decimated image; reconstructing means for reconstructing the moving parameters of the HD image from the moving parameters obtained from the decimated image and the difference information; and image processing means for executing image processing on the decimated image using the moving parameters of the HD image.
