A display control unit executes an information code display process in which a display unit is controlled to change a luminance of a light color display area, in which light color cells are to be displayed, from a luminance of a predetermined initial display screen on the display unit in a certain direction, and to change a luminance of a dark color display area, in which dark color cells are to be displayed, from the luminance of the predetermined initial display screen in an opposite direction to the certain direction.

Information code display device and information code display system

An information code reading system including an information code display device and an information code reading device. The information code display device generates, corresponding to an information code to be displayed, multiple partial code images to be different from one another. A code area of the information code to be displayed includes multiple cells and each cell is included in at least one of the multiple partial code images. Each partial code image is generated by removing a part of the cells from the code area to be different from one another. The multiple partial code images are displayed on a display screen in a cyclic manner. The information code reading device captures, as an information code, an image of the display screen with an exposure time set to be longer than a cycle of cyclic display of the multiple partial code images, and decodes the captured information code.

Information code reading system

There is provided a system that uses a two-dimensional information code. The system administers an information code which is provided with a data recording region and an image region. The system is provided with a specific information acquisition section that acquires specific information of a subject or an object, as information recorded in the data recording region, or as information to be correlated to the information recorded in the data recording region. Further, the is provided with a unique image acquisition section that acquires a unique image of a subject or an object, or a unique image for specifying the subject or the object, as information indicated in the image region. Further, the system is provided with a registration section that registers specific information acquired by the specific information acquisition section, being correlated to a unique image acquired by the unique image acquisition section.
