Abstract: An electronic device includes a display unit, a memory and a processor. The display unit displays at least one of a first display representing a code display and a second display representing a display other than the code display. The processor performs a first display process and a second display process. The first display process controls the display unit such that the display unit performs the first display with contrast ratio of the display unit, based on a contrast data item for first display stored in the memory. The second display process controls the display unit such that the display unit performs the second display with contrast ratio of the display unit, based on a contrast data item for second display stored in the memory.

Abstract: An electronic device including a display, a memory that stores instructions, and a processor. The processor, under control of the instructions, performs processes including a first display process of controlling the display such that the display displays a code while setting the display with a contrast ratio; and in a case where the code is displayed on the display, a contrast change process of automatically changing the contrast ratio of the display at each of intervals, each of the intervals corresponding to a first duration of time.
