Abstract:
A code image data output apparatus which outputs code image data corresponding to multimedia information including at least one of voice information and image information to a recording device for recording the multimedia information on a recording medium as an optically readable code image, comprising:input means for inputting the multimedia information;compression coding means for compression-coding data corresponding to the multimedia information input by said input means; andcode conversion means for converting the data compression-coded by said compression coding means into code data, converting the code data into optically readable code image data according to a predetermined recording format, and outputting the code image data, whereinsaid compression coding means includes data amount calculation means for calculating, in advance before the code image is recorded, a data amount of the compression-coded data corresponding to the multimedia information input by said input means, andsaid code conversion means includes precode generation means for generating precode image data determined on the basis of the data amount calculated by said data amount calculation means and outputting the precode image data before the code image is recorded.
