Two-dimensional code display system, two-dimensional code display method, and program

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.

What is claimed is: 
     
         1 . A two-dimensional code display system comprising:
 a display unit which is capable of displaying a synthesis image of a predetermined image and a two-dimensional code that represents predetermined information by a plurality of cells arranged in a matrix;   a memory unit for storing a plurality of two-dimensional codes each having a different proportion of a colored pattern in a cell; and   a display control unit for controlling the display unit to sequentially display one of the plurality of two-dimensional codes at a time.   
     
     
         2 . The two-dimensional code display system according to  claim 1 , wherein the memory unit includes a layer structure formed by stacking the plurality of two-dimensional codes in a predetermined order. 
     
     
         3 . The two-dimensional code display system according to  claim 1 , wherein the plurality of two-dimensional codes stored in the memory unit further comprises another plurality of two-dimensional codes each having a different shape of the colored pattern in a cell. 
     
     
         4 . A two-dimensional code display method for controlling a display unit to display a synthesis image of a predetermined image and a two-dimensional code that represents predetermined information by a plurality of cells arranged in a matrix, the method comprising:
 controlling the display unit to sequentially display one of a plurality of two-dimensional codes at a time wherein the plurality of two-dimensional codes each has a different proportion of a colored pattern in a cell.
