摘要： In recording dots corresponding to the data to be recorded in the record transmission path, the dots are recorded optically readably so that the recorded data may be reproduced by using two-dimensional interference from the adjacent dots. In reproducing data, after the code image has been processed by equalization in the PR-equalization portion, and simultaneously based upon the reading point position information detected in the reading point calculation portion, the values in the reading points are judged, and in the decoding portion, these read data are judged and decoded based upon the predetermined decoding rules, and they are converted into the original data.

摘要： An information recording medium (30) has a recorded system control file (SCF) (96) representing processing parameters necessary for reproduction processing for reading out a print-recorded code pattern and reproducing original multimedia information. With an SCF readout switch (88) operated, an initially determined SCF read-out parameter is input from a parameter memory (92) to a controller (66). The controller (66) controls each part in accordance with the input parameter and outputs read-out image data as a 1-SDU1 to an overlying layer and a state signal, that is, a signal showing that the SCF is being read out, as a 1-SDU2 to the overlying layer. The overlying layer decodes the contents of the SCF (96) and a parameter setting signal is input as the 1-SDU3 from the overlying layer and it is stored in the layer 1 parameter memory (92). At a time of reading out an actual dot code (10) corresponding to the operation of a scanning start switch (86) the parameter memory (92) utilizes its stored contents.

摘要： A compressed data amount calculation section calculates the data amount of compression-coded data corresponding to input multimedia information in advance before a code image is recorded. A precode image data generation section generates precode image data determined on the basis of the calculated data amount and displays the precode image data on a display section. The user changes various coding parameters through a user setting section while observing the displayed precode image data to regenerate the precode image data, thereby obtaining the desired size. A code image data generation section generates actual code image data in accordance with the changed coding parameters.
