The camera 20 for taking a picture at a predetermined position of the folded and exposed surface of the flip 12 is configured, and the battery 108 is configured on a rear surface of the main body 14 in a known detachable manner.

1 to 3 illustrate one of the configuration examples of a conventional mobile phone, and an example of such a configuration does not limit the technical idea of the present invention. It is apparent that the present invention may be variously limited to the scope of the technical idea described in the detailed description.

On the other hand, the flash 16 has a connection terminal (not shown) to be connected to a connection port (not shown) configurable to the main body 14, the connection terminal is formed by the contacts (extended to the connection port of the main body 14 ( (Not shown) is configured to interface with the control signal and the power supply, and for this purpose, it may be configured in the form of a conventional round 4 terminal.

As described above, when the user wants to take a picture by configuring the embodiment, the user flips the flip 12 and positions the camera 20 in a desired direction.

When the flip 12 is flipped, the mobile phone 10 is switched to the power-on mode, and the user rotates the flash 16 installed on the side of the main body 14 to provide illumination for taking a desired picture.

Thereafter, a picture can be taken by operating buttons in a predetermined order for taking a picture, and the flash 16 provides an illumination state for emitting light at the moment of taking the picture.

It is preferable that the cellular phone 10 has the circuit diagram of the block diagram of FIG. 4 for the photographing and the call operation of the above-described embodiment.

Referring to FIG. 4, the camera module 30 corresponding to the camera 20 included in the flip 12 and the flash module 32 corresponding to the flash 16 of the main body 14 are configured. 30 and the flash module 32 are configured to receive the necessary power from the power supply 46.

In addition, the control unit 38 is configured to control the operation of each unit. Specifically, the control unit 38 includes a handset module 42 for a call, a memory 48 for data storage, and a wireless module 40 for wireless transmission and reception. ), The liquid crystal module 36 for driving the liquid crystal 34 is connected and controlled, and the control unit 38 is configured to control the operation of the camera module 30 and the flash module 32.

In addition, a key matrix 44 for selecting a call mode, a photo capture mode, and the like by the user is connected to the controller 38.

The power supply 46 supplies power for the operation of the liquid crystal 34, the liquid crystal drive module 36, the control unit 38, and the handset module 42.

Accordingly, when the user selects the mode for the call by operating the key matrix 44, the controller 38 controls the handset module 42 and the wireless module 40 to control call attempts and connections. In addition, the reading / writing of data accompanying the data is interactively performed with the memory 48, and the information to be processed is displayed on the liquid crystal 34 by controlling the liquid crystal driving module 36.

The progress information herein refers to the inclusion of a letter or logo indicating a call attempt digit indication, a dialing state, and the like.

If the user selects a mode for photographing by operating the key matrix 44, the controller 38 controls the camera module 30 and the flash module 32.

Accordingly, when the photographing is selected by the user by the operation of the key matrix 44, the camera module 30 captures the captured image and temporarily stores the captured image in the memory 48 through the control unit 38 to secure illumination. In order to control the control unit 38, the flash module 32 controls the flash 16 to emit light at the time of photographing.

Then, a high quality captured image having sufficient illuminance is temporarily stored in the memory 48 as digital information, and then wireless transmission or storage of the image can be performed by a function that can be predetermined according to a user's selection. have. It is apparent that the provision of additional functions for this purpose can be variously implemented by those skilled in the art.

As described above, the flash module 32 may be operated by using a power source of the battery 108 detachable for the operation of the mobile phone 10. In this case, the battery 108 is included in the power supply 46. Have

However, since a large amount of current consumption is instantaneously generated for the flash operation, the adoption of an auxiliary power source for the flash may be considered.

That is, corresponding to the power supply unit 46 of FIG. 4, the power supply unit 40a is configured to have a main power supply 50 and an auxiliary power supply 52, and the flash module 32 is connected to either the main power supply 50 or the auxiliary power supply 52. 5 may be configured to be selected by the switch 54 to supply power.

Referring to FIG. 5, the flash module 32 includes a booster 56, a resistor R1 and a capacitor C1 connected in parallel thereto, an inductor L1 and a switch SW connected in parallel thereto, and in parallel to the capacitor C1. The lamp L which emits light is comprised. In this case, the switch SW is turned on / off by the control signal LS applied from the controller 38, and accordingly, the lamp L is supplied to the voltage charged through the booster 56 and charged in the capacitor C1. It emits light instantly.

The interface for supplying power to the flash module 32 and the interface for providing the control signal LS may be formed by the contact between the aforementioned connection terminal and the connector.

Here, the main power source 50 is a power source for the operation of the mobile phone 10 including a normal call and the auxiliary power source 52 may be configured as a battery that can be built in the cover of the flash for the flash operation.

In a normal state, the auxiliary power supply 52 supplies power through the boosting unit 56 for the flash operation, and when the power supply of the auxiliary power supply 52 is depleted, the switch 54 is switched to boost the power using the main power supply. Power may be supplied through the unit 56.

In this case, the switch 54 may be implemented as a mechanical switch or a switch that is converted into an electronic form by changing the battery switching mode according to the manipulation of the button, which may be variously implemented according to the intention of the manufacturer.
