And when applicable, it transfers to the process of step ST15.
If not, the process proceeds to step ST16.

  In step ST15, the signal processing unit 57 causes the LED array 61 to display an image as defined in the process setting table.

In step ST16, it is determined whether or not processing has ended. If the process has not been completed, the process proceeds to step ST11 again.
On the other hand, when the process is finished, the process is finished.

By doing in this way, the image display according to the surrounding environment can be performed automatically.
Thereby, the user can use the mobile phone 1 more comfortably without any special operation.

<Second Modification>

Moreover, you may be based on the image information which the camera part 13 which the memory | storage part 56 memorize | stored has not image | photographed.
Below, the 4th modification is demonstrated.

  FIG. 12 is an explanatory diagram of a fourth modification.

  In step ST21, the user selects one of the image data stored in the storage unit 56.

In step ST <b> 22, the signal processing unit 57 determines whether the image data is the light emission pattern data of the LED array 61.
When the image data is the light emission pattern data of the LED array 61, the process proceeds to step ST24.
On the other hand, when the image data is not the light emission pattern data of the LED array 61, the process proceeds to step ST23.

  In step ST <b> 23, the signal processing unit 57 performs data change processing so that a light emission pattern is obtained.

  In step ST24, the correction process by the user is received.

  In step ST <b> 25, the signal processing unit 57 performs light emission processing of the LED array 61.

By such a method, the design of the mobile phone 1 can be changed based on the image information stored in the mobile phone 1.
This has the effect that the user can easily change the design of the mobile phone 1.
