DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an information recording medium, such as paper, recording, as an optically readable code pattern, so-called multimedia information including, for example, audio information such as a speech and music, video information obtained from a camera, a video device, etc., and digital code data obtained from a personal computer, a word processor, etc., and an information reproducing apparatus optically reading out a code pattern recorded on such an information recording medium and reproducing its original multimedia information.
BACKGROUND ART
Various media, such as a magnetic tape, an optical disc, etc., have been conventionally known as media for recording speech, music, etc. These media, being manufactured in large quantities, become higher in unit cost and occupy greater space. Further, if there arises the need to send a speech-recorded medium to a person in a far-away place or places, it takes more time and trouble even if it is mailed to him or her or it is carried with him or her in person. The same thing can also be true about the so-called multimedia information including in addition to audio information, video information obtained from a camera, video device, etc., as well as digital code data obtained from a personal computers word processors, etc.
The applicant has conceived a system for recording multimedia information containing at least one of audio information, video information and digital code data, in dot-code form, on an information recording medium such as paper, that is, the multimedia information as image information, ie., coded information, capable of facsimile transmission and of copying in large quantities at low cost and a system for reproducing such recorded multimedia information and filed the invention as an international application PCT/JP93/01377 (WO 94/08314).
In the information reproducing system of this international application, the information reproducing apparatus is adapted to achieve reproduction operation by optically reading out the dot code from the information recording medium and adapted to achieve read-out operation by manually scanning the recorded medium along the recorded dot code while carrying the apparatus by hand.
The dot code pattern per se is now under investigation to improve the recording density and the information recording medium and information reproducing apparatus filed under the above international application have not been fully considered in terms of their flexibility and versatility on a future change or modification.
DISCLOSURE OF THE INVENTION
It is accordingly the object of the present invention to provide an information recording medium and information reproducing apparatus which, even if the configuration of a code pattern itself varies in the future, can cope with this situation.
In order to achieve the above-mentioned object, there is provided an information recording medium having an area recording as an optically readable code pattern, multimedia information containing at least one of audio information, video information and digital code data, characterized in that the code pattern contains processing information necessary to subject the data to edit processing in accordance with a reproduction process for reproducing original multimedia information by reading out the code pattern.
Or an information recording medium of the present invention has an area recording, as an optically readable code pattern, multimedia information containing at least one of audio information, video information and digital code data, characterized in that reproducing means, adapted to be applied to the information recording medium for reading out the code pattern and for reproducing the code pattern to original multimedia information at least comprises first layer processing means for converting the read-out code pattern to code data as an image and for delivering an output with information related to the read-out attached as first processing information to the code data; second layer processing means for reco
