Abstract

A two-dimensional code display system has a display unit which can display a two-dimensional code representing predetermined information by plural cells arrange in a matrix, and a control unit which changes the display form of the two-dimensional code. For example, after 0.5 second has elapsed since the display unit starts displaying the image of a logo mark, the control unit controls the display unit to change the display from the image of the logo mark to a two-dimensional code. After 2.0 seconds has elapsed since the display unit starts displaying the two-dimensional code, the control unit controls the display unit to change the display from the two-dimensional code to the image of the logo mark. By repeating such control, the control unit can control the display unit to display alternately the image of the logo mark and the two-dimensional code.

Claims

1. A two-dimensional code display system comprising:

a display unit which is capable of displaying a two-dimensional code representing predetermined information by plurality of cells arranged in a matrix; and

a display control unit for changing a display form of the two-dimensional code, wherein

the display control unit controls the display unit to intermittently and visibly display the two-dimensional code, and controls the display unit to visibly display a predetermined image while the two-dimensional code is not displayed, the predetermined image being different form a two-dimensional code.

2. The two-dimensional code display system according to claim 1, wherein the display control unit repeats a control of changing the display of the display unit to the two-dimensional code after a first period elapses since the display unit starts displaying the predetermined image, and a control of changing the display of the display unit to the predetermined image after a second period elapses since the display unit starts displaying the two-dimensional code.

3. The two-dimensional code display system according to claim 1, wherein the display control unit controls the display unit to sequentially change and display plural two-dimensional codes each representing information having a different content.

4. The two-dimensional code display system according to claim 1, wherein the display control unit controls the display unit to display an image while the two-dimensional code is not displayed, the image visibly representing a content of the information represented by the two-dimensional code.

5. A two-dimensional code display method for controlling a display unit to display a two-dimensional code representing predetermined information by a plurality of cells arranged in a matrix, the method comprising:

a display control step of changing a display form of the two-dimensional code, wherein

in the display control step, the display unit is controlled to intermittently and visibly display the two-dimensional code and to visibly display a predetermined image while the two-dimensional code is not displayed, the predetermined image being different from a two-dimensional code.

6. The two-dimensional code display method according to claim 5, wherein in the display control step, the display unit is controlled to sequentially change and display plural two-dimensional codes each representing information having a different content.

7. The two-dimensional code display method according to claim 5, wherein in the display control step, the display unit is controlled to display an image while the two-dimensional code is not displayed, the image visibly representing a content of the information represented by the two-dimensional code.

8. A non-transitory computer-readable recording medium recording a program that allows a computer to function as:

display control means for changing a display form of a two-dimensional code when a display unit is controlled to display the two-dimensional code, the two-dimensional code representing predetermined information by a plurality of cells arranged in a matrix, wherein

the display control means controls the display unit to intermittently and visibly display the two-dimensional code, and controls the display unit to visibly display a predetermined image while the two-dimensional code is not displayed, the predetermined image being different from a two-dimensional code.

9. The non-transitory computer-readable recording medium recording a program according to claim 8, wherein the display control means controls the display unit to sequentially change and display plural two-dimensional codes each representing information having a different content.

10. The non-transitory computer-readable recording medium recording a program according to claim 8, wherein the display control means controls the display unit to display an image while the two-dimensional code is not displayed, the image visibly representing a content of the information represented by the two-dimensional code.
