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 unit is capable of displaying a synthesis image of a predetermined image and the two-dimensional code; and

the display control unit controls the display unit to display the synthesis image while changing a proportion of a colored pattern contained in the cell.

5. The two-dimensional code display system according to claim 1, wherein the display control unit allows the two-dimensional code to represent the predetermined information by gradually increasing the proportion of the colored pattern after a first period elapses since the display unit starts displaying the predetermined image.

6. The two-dimensional code display system according to claim 1, wherein the display control unit causes the two-dimensional code not to represent the predetermined information by gradually decreasing the proportion of the colored pattern after a second period elapses since the proportion of the colored pattern becomes the maximum.

7. The two-dimensional code display system according to claim 1, wherein the display control unit controls the display unit to display the synthesis image while changing the proportion of the colored pattern by sequentially changing and displaying plural kinds of two-dimensional codes each having a different proportion of the colored pattern.

8. The two-dimensional code display system according to claim 1, wherein the display control unit controls the display unit to display the synthesis image while changing a shape of the colored pattern.

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

a display control step of controlling the display unit to display a synthesis image of a predetermined image and the two-dimensional code while changing a proportion of a colored pattern contained in the cell.

15. The two-dimensional code display method according to claim 12, wherein in the display control step, the display unit is controlled to display the synthesis image while changing a shape of the colored pattern.

16-18. -18. (canceled)

19. A 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 representing predetermined information when a display unit is controlled to display the two-dimensional code by plurality of cells arranged in a matrix, wherein

the display control means controls the display unit to display a synthesis image of a predetermined image and the two-dimensional code while changing a proportion of a colored pattern contained in the cell.

22. The computer-readable recording medium recording a program according to claim 19, wherein the display control means controls the display unit to display the synthesis image while changing a shape of the colored pattern.
