摘要:
A sensing section reads the dot codes by optically scanning a recording medium on which multimedia information has been recorded in the form of optically readable dot codes. The thus obtained dot codes are processed and restored to the original multimedia information by a scanning conversion section, a data string adjusting section, an error correction section, a reproducing section and a controller. An output unit reproduces each piece of information and outputs them. In this case, on the basis of the dot codes thus read, the scanning conversion section and controller sense information reproduction parameters, such as the dot size. The sensed parameters are then stored in a parameter memory. According to the parameters stored in the parameter memory, the dot codes are then subjected to a reproducing process.
摘要:
A dot code recorded on an information recording medium consists of a data code corresponding to the contents of multimedia information to be reproduced, and a pattern code for determining a read reference point for the data code. The pattern code consists of pattern dots arranged at predetermined positions with respect to the data code, and markers arranged at predetermined positions with respect to the pattern dots and used to detect the pattern dots. In an information reproduction system for optically reading and reproducing a dot code from an information recording medium on which such a dot code is recorded, the dot code is imaged by an image input section. A data read reference point determining section then recognizes the pattern code from the picked-up image, and determines a data read reference point for reading the data code. A data reading section reads the data code on the basis of the data read reference point determined by the data read reference point determining section. A reproducing section reproduces/outputs the data read by the data reading section.

A marker detecting section detects markers formed at four corners of a block using binary image data of a two-dimensional code stored in a data memory. A marker's approximate center calculating section calculates the approximate centers of the detected markers. A pattern code detecting means detects a pattern code in accordance with format information of the two-dimensional code stored in a format memory. A marker's real center calculating section calculates the real centers of the markers from the detected pattern code and the format information using the error minimizing method. Based on the calculated real centers of the markers, a data code reading coordinate calculating section calculates reading coordinates for reading data dots of address code and data code areas from the data memory.
