Method and apparatus for operating projection mode in projection device

摘要

A projection device capable of automatically controlling on/off of a projection module for projecting display data onto an exterior surface according to an open/closed state of a cover of the projection module, and an operation method thereof are provided. The method for operating a projection module in a projection device includes turning-on the projection module when a first detection signal is detected, wherein the first detection signal is generated when a cover of the projection module is open, and after the projection module is turned on, turning-off the projection module when a second detection signal is detected, wherein the second detection signal is generated when a cover of the projection module is closed.

1. A method for operating a projection mode in a projection module is mounted in a portable terminal or is configured in an external type, the method comprising:
opening a cover of the projection module according to a sliding type moving; detecting a detection signal from a state sensor while performing an operation in a normal mode, the detection signal being generated when the cover of the projection module is open; automatically turning-on the projection module for projecting a various external screen data when the detection signal is detected and a display module of the portable terminal is in an on state; displaying an internal screen data to operate a function of the projection module on a display; and outputting an audio corresponding to the various external screen data be projected to an exterior through an audio processing unit according to execution of the function of the projection module; and storing data associated with control of operation corresponding to the function of the projection module, wherein the detection signal is generated when the cover approaches within a recognition range of the state sensor by a close and/or an open operation of the cover.
