In such a case, there is an advantage that the configuration (s) arranged in the first rear case 100A-2 in the closed state is protected by the second body 100B. Further, even if the second camera module 121-2 is not separately provided, the first camera module 121-1 can be configured to be rotatable so that the second camera module 121-2 can be photographed up to the photographing direction of the second camera module 121-2 .

Hereinafter, with reference to FIG. 4, a description will be given of the organic operation relationship among the respective components in implementing the operation control function in the portable terminal according to the present invention. Fig. 4 is a block diagram showing the constituent elements shown in Fig. 1 that are necessary for the implementation of the present invention.

The control unit 180 measures the temperature of the portable terminal 100 using a thermistor 141 when at least one functional operation mode is selected through the operation unit 130. [ At this time, the thermistor 141 may be included in the sensing unit 140.

Herein, the functional operation mode refers to a state for executing a functional operation that can be implemented in the portable terminal 100, and includes, for example, a broadcasting viewing mode, a multimedia reproducing mode, a video shooting mode, Mode. ≪ / RTI > Of course, the functional operation mode is not limited to the above-described ones, but may include all functional operation modes that can be performed by the portable terminal 100. [

The thermistor 141 is a device having a different resistance value according to temperature, measures the temperature, and transmits the measured temperature to the control unit 180. The controller 180 converts the temperature inputted in the analog form from the thermistor 141 into a digital temperature by using an AD converter (not shown). The AD converter may be provided in the control unit 180 or may be separately provided.

First, in accordance with the first embodiment, the control unit 180 controls the operation of the selected functional operation mode at the measured temperature using the consumed energy amount information at the time of performing the functional operation mode for each temperature stored in the storage unit 160 And calculates the consumed power amount.

When the calculated amount of consumed electric power exceeds the current residual electric power amount of the portable terminal 100, the controller 180 turns off the power of the portable terminal 100 during the selected functional operation mode Output through the A / V output unit 150, or prohibit entry into the selected functional operation mode.

Next, in accordance with the second embodiment, when the temperature measured using the thermistor 141 is lower than a predetermined temperature, the controller 180 turns off the power of the portable terminal 100 during the execution of the selected functional operation mode output via the A / V output unit 150, or prohibit entry into the selected functional operation mode.

Hereinafter, a method of controlling the operation of the mobile terminal according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 5. FIG. Fig. 5 shows a flowchart of a method of controlling the operation of the portable terminal according to the first embodiment of the present invention.

The portable terminal 100 selects a function operation mode corresponding to the selection operation according to a selection operation of the user using the operation unit 130 (S510).

As the functional operation mode is selected, the portable terminal 100 measures the temperature of the portable terminal 100 using the thermistor 141 (S520).

Since the thermistor 141 is an element having a different resistance value depending on the temperature, the temperature can be measured using such a characteristic.

The portable terminal 100 calculates the amount of power consumption at the time of performing the selected functional operation mode at the temperature measured using the thermistor 141 and the current residual power amount of the portable terminal 100 at step S530.

Here, the consumed power amount may be calculated using the consumed power amount information when performing the functional operation mode for each temperature previously stored in the storage unit 160. [ For example, in the storage unit 160, information on the amount of power consumed by each functional operation mode at each temperature may be stored in a table format. The residual power amount can be calculated by measuring the residual power amount of the battery 191 included in the power supply unit 190. [

Then, the portable terminal 100 determines whether the consumed power amount exceeds the residual power amount (S540).

If it is determined that the amount of consumed electric power exceeds the residual power amount, the portable terminal 100 determines that the portable terminal 100 can be powered off when the selected functional operation mode is performed, (S550).

For example, the portable terminal 100 displays a message indicating that the portable terminal 100 can be powered off when the selected function operation mode is performed, through the display module 151 or the sound output module 152 As a voice.

Alternatively, if it is determined that the amount of consumed power exceeds the residual amount of power, the portable terminal 100 prohibits entry into the selected functional operation mode (S560).

For example, when the selected function operation mode is the "multimedia playback mode ", the portable terminal 100 may prohibit the multimedia playback module 181 from entering the" multimedia playback mode "

If it is determined that the amount of consumed power does not exceed the residual power amount, the portable terminal 100 may enter the selected function operation mode and perform the selected function operation mode (S570).

Hereinafter, a method of controlling an operation of a mobile terminal according to a second embodiment of the present invention will be described with reference to FIGS. 1 and 6. FIG. Fig. 6 shows a flowchart of a method of controlling an operation of the portable terminal according to the second embodiment of the present invention.

The portable terminal 100 selects a function operation mode corresponding to the selection operation according to the selection operation of the user using the operation unit 130 (S610).

As the functional operation mode is selected, the portable terminal 100 measures the temperature of the portable terminal 100 using the thermistor 141 (S620).

The portable terminal 100 determines whether the temperature measured by the thermistor 141 is lower than a predetermined temperature (S630).

Since the power consumption of the portable terminal 100 rapidly increases at a low temperature lower than a predetermined temperature (for example, less than -10 ° C), there is a great risk that the power is turned off at the time of performing the specific function operation mode. Accordingly, the present invention proposes a method for preventing a sudden power-off situation when it is determined that the temperature of the portable terminal 100 is lower than a predetermined temperature.

If it is determined that the temperature is lower than the predetermined temperature, the portable terminal 100 notifies the AV output unit 150 that the power of the portable terminal 100 can be turned off at step S640.

Otherwise, if it is determined that the temperature is lower than the predetermined temperature, the portable terminal 100 prohibits entry into the selected function operation mode (S650).

If it is determined that the temperature is not lower than the predetermined temperature, the portable terminal 100 enters the selected function operation mode and can perform the selected function operation mode (S660).

Hereinafter, the configuration of a display screen in the functional mode control process of the portable terminal according to the present invention will be described with reference to FIG.

The mobile terminal 100 displays sub-menu items constituting "multimedia" through the display module 151 when "multimedia"

When the "TV watching" 711 is selected among the submenu items, the portable terminal 100 measures the temperature of the portable terminal 100 or consumes the " TV watching " The amount of power and the amount of residual power are calculated.

When the consumed power amount exceeds the residual power amount or when the measured temperature is lower than a predetermined temperature, the portable terminal 100 is powered off through the display module 151 at the time of watching TV (B) a warning message 721 indicating that it can be done.
