Embodiment Construction

[0051] At first the terms involved in the present invention are defined as follows:

[0052] In this embodiment, the "pixel" is the smallest unit that constitutes an image, the "dot" is the smallest unit of a screen corresponding to the pixel that constitutes the smallest unit of an image, and the "dot of a dot" is the smallest unit that constitutes a dot . "Dots of network dots" are composed of "printing dots", the smallest unit that can be printed by printing equipment.

[0053] The "geometric information embedded code" refers to the distribution of its lattice pattern, according to the distribution of its different positions, the distribution of different directions, the distribution of different shapes, the points of different sizes of dots, the dots of different numbers of dots, Concentration and dispersion of dots are used to record the dot matrix pattern of information, which is called geometric information embedding code.

[0054] The "physical information embedded c...

Abstract

The invention relates to a method for forming a printed matter with an automatic reading function. Specifically, the additional information of an embedded object is converted into a geometrical or physical information recording and embedding code which has printing screen characteristics and is possible for pattern recognition, and the code is embedded into an image of a printing medium file to form the printed matter with the automatic reading function. The printed matter with the automatic reading function is scanned into image data, and a code value of the information recording and embedding code is recognized, thereby achieving an automatic reading effect. The method has the advantages that: document files with great amounts of information are directly embedded into paper medium files, thereby realizing the automatic reading function; and simultaneously, for the paper medium files, the sense of inharmony and reduction in the quality of a printed image can be avoided.

Description

technical field [0001] The present invention relates to an automatic reading system, an information embedding device, an information embedding program, an information identification device, an information identification program and an automatic reading printed matter for an integrated machine. Background technique [0002] In recent years, in order to reduce the cost of storage, use, and management of paper-based documents, according to the implementation of national policies, paper-based documents are rapidly shifting to electronic. However, in order to convert a paper document into an electronic form, the general method is to first scan the paper document with a scanner, and then save it as image data. However, the problem is that image data cannot be edited or directly applied to the database. [0003] On the other hand, among the representative methods of reading technology, "character reading device" [character reading device] (JP-A-6-333086) and "reading device and re...
