TWO-DIMENSIONAL COLOR CODE DISPLAY DEVICE AND DISPLAY METHOD FOR THE SAME, AND TWO-DIMENSIONAL COLOR CODE READING DEVICE AND READING METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a two-dimensional color code display device capable of reducing error in reading a two-dimensional color code.SOLUTION: A two-dimensional color code display device 10 comprises: a two-dimensional color code generation part 11 which generates a two-dimensional color code 22 corresponding to data 21; a correction frame output part 12 which outputs a correction frame 23 used to correct a color of the two-dimensional color code; a display frame selection part 13 which selectively outputs the two-dimensional color code 22 and the correction frame 23; and a display part 15 which displays the two-dimensional color code or correction frame output from the display frame selection part.
