Claim 4:
5. The device of claim 4, wherein the at least one processor is further configured to:
determine whether a first ratio of the fourth length of the second QR image to the first length of the first QR image is equal to or less than a first predetermined value;
store the second QR image in the memory when the first ratio is equal to or less than the first predetermined value;
reduce the first weight, calculate a fourth length of a new second QR image generated through the image conversion, and determine whether a ratio of the fourth length of the new second QR image to the first length of the first QR image is equal to or less than the first predetermined value, when the first ratio is greater than the first predetermined value;
determine whether a second ratio of the fifth length of the second QR image to the second length of the first QR image is equal to or less than the first predetermined value, and store the second QR image in the memory when the second ratio is equal to or less than the first predetermined value; and
reduce the second weight, calculate a fifth length of a new second QR image generated through the image conversion, and determine whether a ratio of the fifth length of the new second QR image to the second length of the first QR image is equal to or less than the first predetermined value, when the second ratio is greater than the first predetermined value,
wherein the first predetermined value is selected from a range of 1 to 1.4.
