An electronic device includes a display and a control unit. The control unit includes a processor and functions, when the processor executes a control program, as a screenshot executing section and a control section. The screenshot executing section acquires an image being displayed on the display. The control section performs authentication processing authenticating a user. When an image that requires authentication of the user is being displayed on the display, the control section forbids the screenshot executing section to acquire the image. When an image that requires no authentication of the user is being displayed on the display, the control section permits the screenshot executing section to acquire the image.
