Abstract
An electronic whiteboard includes a power button, a display device, and circuitry that implements processes of detecting an operation of the power button being turned off, storing at least a part of visible information displayed on the display device from a time the power button was turned on until a time the power button was turned off in a first storage device upon detecting that the power button has been turned off, determining whether to display the visible information stored in the first storage device on the display device based on a first time corresponding to a power-on time recorded when the power button was turned on and a second time corresponding to the power-off time recorded immediately before the first time when the power button was turned off, and controlling the display device to display the stored visible information upon determining to display the stored visible information.
