摘要： A reading unit optically reads a code including a plurality of blocks arranged in accordance with a predetermined block layout format by sensing the code to include a plurality of blocks within one image sensing frame. A block detection unit detects the blocks from the code read by the reading unit. An address data acquisition unit acquires address data of the blocks detected by the block detection unit. A block data decoding unit decodes block data from the data patterns of the blocks detected by the block detection unit. An information data reproduction unit reproduces original information data by coupling the block data decoded by the block data decoding unit in accordance with the address data acquired by the address data acquisition unit. An image sensing state discrimination unit discriminates the image sensing state of the code read by the reading unit. A block decoding control unit controls the block data decoding unit based on the code image sensing state discriminated by the image sensing state discrimination unit so as to preferentially decode appropriately sensed blocks of the plurality of decodable blocks.

摘要： A binarizing section generates binarized data from an image signal of a dot code on an information recording medium read by a code reading section. The binarizing section has a reference dot detection section, a dot area measuring section, a threshold value modifying section and a threshold value determining section. The reference dot detection section binarizes the image signal with a predetermined threshold value prior to generating binarized data to detect a reference dot from a binarized code image. The dot area measuring section measures the area of the reference dot detected by the reference dot detection section. The threshold value modifying section modifies the threshold value for binarization in such a manner that the area measured by the dot area measuring section approaches a predetermined target value. The threshold value determining section binarizes the image signal with the threshold value modified by the threshold value modifying section.

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.

摘要： A spectacles-type image display device comprises an image output unit for outputting image light of images to be displayed and a reflection unit disposed in a field of view of at least one eyeball of a viewer. The reflection unit is adapted to reflect the image light output from the image output unit toward the eyeball of the viewer so that the viewer can see virtual images of the images. The minimum value of a width of a projection cross-section of the reflection unit in an output direction of the image light to the eyeball is smaller than a dark-adapted pupil diameter of human and is larger than a light-adapted pupil diameter of human.
