Abstract: A shared terminal for displaying an image to be viewed by a plurality of users on a display is provided. The shared terminal includes circuitry to receive an instruction to turn on the shared terminal according to operation of a power switch, and determine whether login authentication and redisplay of a previously-displayed image are individually set. The previously-displayed image is an image that has been previously displayed when the circuitry receives an instruction to turn off the shared terminal. The circuitry further causes the display to redisplay the previously-displayed image in response to the instruction to turn on, based on a determination that the login authentication is not set and the redisplay of the previously-displayed image is set.
