摘要： Provided are an image processing apparatus, method, computer program and recording medium capable of embedding a large quantity of additional information in image information upon dispersing the information in such a manner that it will not be noticeable visually. An error correction code is calculated from additional information [x(i)] to be added to image information (D1), and multiplexed information [y(j)] in which the error correction code has been added to the additional information is generated by an error correction encoder (13). Next, the bit sequence of the multiplexed information [y(j)] that has been generated is rearranged into a prescribed bit sequence by a shuffling unit (14), whereby multiplexed information [z(j)] is generated. Furthermore, the multiplexed information [z(j)] whose bit sequence has been rearranged is embedded in the image information (D1) by an additional-information multiplexer (15), whereby image information (D2) is generated. The image information (D2) in which the multiplexed information [z(j)] has been embedded is printed by a printer (16) and is output as a printed image (17).

摘要： A maximum embedding amount can be ensured depending on information to be embedded, by determining an error-correction capability in correspondence with the characteristic of embedded information. For this purpose, upon multiplexing additional information, the additional information is error-correction encoded. At this time, if the additional information is a BMP file, a WAV file or the like, coding is performed with a low error-correction capability since image reproduction can be made without serious problem even if the error-correction capability is low. The error-correction capability is determined by an error-correction parameter determination unit 205 based on an extension of the additional information.
摘要翻译：通过根据嵌入信息的特性确定纠错能力，可以根据要嵌入的信息确保最大嵌入量。为此，在复用附加信息时，附加信息被纠错编码。此时，如果附加信息是BMP文件，WAV文件等，则以低纠错能力进行编码，因为即使纠错能力低，也可以进行无严重问题的图像再现。基于附加信息的扩展，由纠错参数确定单元205确定纠错能力。

摘要： With this invention, upon scanning a print, since additional information recorded together with that print is reproduced while displaying the scanned image, a special effect that cannot normally be obtained from still images can be obtained.A print on which image information and additional information, different from the image information, are printed is scanned by a scanner (209). An additional information demultiplexer (210) demultiplexes that additional information, which is decoded by an error correction decoder (211). After that, the image and the decoded additional information (moving image or/and acoustic information) are simultaneously reproduced in combination.
