First, a power OFF signal is input to the portable imaging device 100 (step 601).

When the photographer inputs a power OFF signal through the power button 12, the controller 37 does not immediately turn off the power of the portable photographing apparatus 100, but the photographing apparatus 100 moves in a specific direction. It is determined whether it is inclined (step 602). In this case, the direction detecting sensor 38 detects a direction to which the portable photographing apparatus 100 is directed and outputs it to the controller 37, and the controller 37 determines whether the direction is a preset direction to perform a specific operation. (Step 602).

If the power-off signal is input in a state in which the portable photographing apparatus 100 faces a specific direction, for example, a direction corresponding to a function set by a user, the controller 37 controls the specific function set in the specific direction. After performing (or a mode) (step 603), the power of the portable photographing apparatus 100 is turned off (OFF), thereby terminating the entire operation of the portable photographing apparatus 100 (step 604).

As a specific function (or mode) that can be performed while terminating the operation of the portable photographing apparatus 100, for example, after performing an operation of removing dust from a CCD (not shown) of the portable photographing apparatus 100. The power may be turned off, or the storage unit 36 may generate a new folder in which the image to be captured will be stored at the next shooting of the portable photographing apparatus 100, and then turn off the power of the portable photographing apparatus 100 ( OFF). In addition, after initializing the setting values of the various modes converted in the photographing process, the power of the portable photographing apparatus 100 may be turned off.

If the power-off signal is input while the portable photographing apparatus 100 faces a direction other than a specific direction set by the user, the power is immediately turned off to terminate the entire operation of the photographing apparatus 100. (Step 604). Of course, even in this case, instead of immediately turning off the power of the photographing apparatus 100, as in the above-described embodiment, it is determined whether the user generates a signal by another function (or mode) button and the corresponding signal. May occur, and after performing a corresponding function (or mode), the power of the photographing apparatus 100 may be turned off.
