Definitions
- the present invention relates to an information input / output method using a dot pattern for inputting / outputting various information and programs by optically reading dot pattern information formed on a printed material or the like.
- an information output method for reading a barcode printed on a printed matter or the like and outputting information such as sound For example, a method has been proposed in which information that matches key information given in advance to storage means is stored, information is retrieved from a key read by a bar code reader.
- a dot pattern in which fine dots are arranged according to a predetermined rule is generated, and the dot pattern printed on a printed material is captured as image data by a camera and digitized for audio information.
- a technique for outputting a signal has also been proposed.
- the above-described conventional method of outputting sound or the like by using a barcode has a problem that the barcode printed on the printed matter is annoying.
- the barcode occupies a part of the large paper surface, if the barcode is large in this way, a character that has the meaning of appearing in a part of a sentence or sentence, or in a picture, picture, or graphic image. In other words, it was difficult to assign a large number of barcodes for each object and it was impossible to layout.
- a dot pattern is captured as image data by a camera, the image data is digitized into 256 gray levels, and the change in the gray level is differentiated in order to recognize the dot.
- the edge of the dot is obtained by comparing with a predetermined threshold value.
- 256-level data is converted into white or black.
- This binary value causes a printing error when printing dots on paper, due to printing misalignment and blurring, and misalignment when pixelated.
- printers were checked for errors using a parity check.
- these error checks are more complicated than the dot-by-dot printer checks. There was a problem in that it was impossible to determine which dot had a printing error and to have a wide imaging range of the camera by checking for errors in the data cluster obtained from a number of dots. .
- the imaged dot pattern is distorted due to lens distortion and oblique imaging, expansion and contraction of the paper surface, media surface curvature, and distortion during printing, and advanced technical skills are required to correct this. Then there was a problem.

- dot misalignment when printing on the media surface paper surface
- dot center misalignment when digitally entering wrinkles on the printing paper surface
- dot pattern when shooting from an oblique direction of the optical reading means Even if deformation occurs, the analysis can be performed using the quasi-reference lattice points.
- At least one of the reference grid dots or the quasi-reference grid dots constituting the block is arranged at a position shifted from the virtual grid point, and the shifted direction is the direction of the block.
- the direction of the dot pattern can be recognized when read by the optical reading means. Therefore, by changing the meaning of the information dot read for each direction, it is possible to define a larger amount of information as a dot pattern.
- Claim 5 of the present invention is characterized in that the blocks are continuously arranged in an arbitrary region in the vertical and horizontal directions, and the reference grid dots are shared by the blocks in the vertical direction. This is an information entry / exit method using the dot pattern described in Item 1-14.

Therefore, information dot 5 can be easily read.

In this case, it is placed on the leftmost vertical reference grid line If a random number is used for the information dot (the initial value in the difference), the positions of the dots placed thereafter (rightward) become irregular, and the dot pattern can be prevented from being visually patterned.
- FIG. 5B shows an example in which quasi-reference grid point dots are arranged on the grid line C in FIG.

- FIG. 16B is an example in which quasi-reference lattice points are provided in the dot pattern of FIG. 16A.
