  • Patent number: 9319507
    Abstract: Disclosed are an apparatus and a method for forming an event picture in a mobile communication terminal. If an event such as call reception, alarm or message reception occurs while a service picture is displayed on a screen of the terminal, the current service picture is backed up, a command input through the buttons provided to the terminal is interrupted and the event picture is overlapped over the current service picture, thereby allowing a user to perceive the corresponding event. Accordingly, the terminal user can correctly perceive the event occurred during the service. In addition, when the event occurs, the command input through the buttons is interrupted, so that it is possible to prevent an unintended event processing or erroneous operation due to an erroneous button manipulation.
