  • Publication number: 20210383088
    Abstract: 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.
