Abstract
An electronic device includes: display controller; user presence determination module; user authentication module; and controller. The user presence determination module determines presence of a user based on image data received from the camera while dominating access to a camera. The user authentication module dominates access to the camera, if the display is put in a screen lock state and to perform a user authentication based on the image data. The controller turns off the display if the user present determination module determines that the user is absent and while the display has not been put in the screen lock state, and to cause the user presence determination module to release the access to the camera and to put the display in the screen lock state before turning on the display if it is determined after the display is turned off that the user is present.
