  When a code pattern with an error correction rate of 15 percent with different opacity is read and decoded with an NEC DoCoMo mobile phone N900i manufactured by NEC, the opacity is 100 percent to 20 percent when the code pattern is displayed on the display. When the code pattern was laser-printed on plain paper, it was decoded well when the opacity was in the range of 100 percent to 10 percent.

  Accordingly, the first opacity is set to a value of 20 percent or more and less than 100 percent in a case where the code pattern after image synthesis based on the composite image data 25 is displayed on the display. When the code pattern after image synthesis based on the above is printed, it is preferable that the value is 10% or more and less than 100%.

As described above, according to the above embodiment, the code pattern image data 21 from 0 percent than high and rather low than 100 percent, and the code pattern is one of the values in the decodable range alone Code pattern translucent image data 23 having an opacity of 1 is generated, and translucent image data 24 having a second opacity higher than 0 percent and lower than 100 percent is generated from the overlay image data 22. Then, based on the code pattern translucent image data 23 and the superimposing translucent image data 24, composite image data of a composite image obtained by superimposing the first opacity code pattern and the second opacity superimposition image. 25 is generated.

  Thereby, it is possible to visually recognize the superimposed image while making the code pattern decodable, and it is possible to realize a code pattern with improved design.

  Further, according to the above embodiment, the first opacity is any value within a range where the code pattern can be decoded alone. Thereby, it is possible to satisfactorily perform decoding from the code pattern included in the composite image.

  Further, according to the above-described embodiment, it is preferable that the first opacity is 50% and the second opacity is any value between 50% and 60%. As a result, it is possible to satisfactorily visually recognize the superimposed image while enabling the code pattern to be satisfactorily decoded, thereby realizing a code pattern with improved design.

  Further, according to the above embodiment, the code pattern 111 after image synthesis is printed on the medium 101 based on the synthesized image data 25. Thereby, since the code pattern 111 can be decoded and the image for superimposition can be visually recognized, the code pattern which improves designability on various media can be realized.

  Further, according to the above-described embodiment, the code pattern 212 after image synthesis is displayed on the display 4 based on the synthesized image data 25. Thereby, since the code pattern 212 can be decoded and the image for superimposition can be visually recognized, it is possible to realize a code pattern that improves designability on various display pages.

  If the opacity of either the code pattern or the superimposing image is 100%, the visibility of the superimposing image is impaired, or the possibility of decoding from the code pattern is impaired.

  The above-described embodiments are preferred examples of the present invention, but the present invention is not limited to these, and various modifications and changes can be made without departing from the scope of the present invention. is there.

  For example, in the above embodiment, a QR code (registered trademark) code pattern which is a two-dimensional code is given as an example of a code pattern, but other types of two-dimensional code, one-dimensional barcode, etc. A code pattern may be adopted.

  In the above embodiment, the superimposition image is a monochrome image on the paper surface, but may be a color image. In that case, the background color of the composite image is white, and the code pattern is a monochrome image. The background color and code pattern of the composite image become colorless and the superposition image becomes a color image, so that the visibility of the superposition image is enhanced.

In the above embodiment, a code pattern image, but each a superposition image so as to synthesize and translucent, for example, superimposition image without, and translucent only Kodopa turn images, It may be printed on a medium by the printer 3 or displayed on the display 4. Even in such a case, an unprecedented beauty can be produced by adjusting the opacity of the code pattern.

  In the above embodiment, the opacity (specifically, for example, the transmittance) of the code pattern image and the superimposing image is adjusted. For example, the hue, brightness, and saturation are adjusted. You may do it.

  In the above embodiment, for example, a transparent or translucent medium can be used as a medium printed by the printer 3. For example, it is possible to print on a transparent member such as an acrylic plate or a translucent member such as frosted glass. By using such a medium, an unprecedented beauty can be produced.

  Furthermore, the printed information may be protected by applying a coating material to the printed portion of the medium. In this case, for example, “vinylidene fluoride (film)” can be used as the coating material. Vinylidene fluoride is also used for traffic signs and the like and has a resistance of more than 10 years. Vinylidene fluoride is characterized by being resistant to scratches, dirt, doodles, and ultraviolet rays.
