Considering the video transmission during the night call at the time of adding a flash function to the terminal relates to a call terminal equipped with a flash function so that video calls can be made without difficulty even at night.

Looking at a similar technology equipped with a flash function in the conventional call terminal, there is no other method than using a low-brightness LED light shining through the keypad as it is or using a separate device or moving to a bright place.

The low-brightness LED light emitted through the keypad was so seaweed that it could not play a definite flash during video calls.

In other words, the light generated from the keypad is very seaweed, so if the user does not pay much attention to using the keypad, there is a problem such as pressing a different number.

In addition, as described above, a method of providing lighting to a terminal using a separate device, or a method of moving to a bright place by pressing a keypad, always provides inconvenience to a user, thereby providing a user with an inconvenience of a mobile phone. It is a technical method that falls behind by greatly undermining the merits of making a call whenever and wherever you want, without being restricted by.

The present invention has been made to solve the above problems, and is also applied to the IMT-2000 terminal, which is being developed as a next-generation mobile communication terminal, to transmit video at night when a camera module should be mounted on the terminal. In consideration of the purpose of adding a flash function to the terminal to enable video calls without difficulty even at night to provide convenience to the user.

In order to achieve the above object, there is a method of mounting a flash on a terminal device with a camera, a method of using a LED light of a keypad for pressing the number of the terminal, a built-in flash method, and the method does not have the lighting of the conventional terminal itself. It was developed based on the inability to accurately convey the outline of the subject.

First, the external flash function is applied to the same equipment as the camera, and the high brightness small bulb is attached to the camera so that the camera can shoot the subject with fluidity and the flash moves the same way.

As a method of using a keypad for pressing the number of the second terminal, the conventional keypad uses a low-brightness LED built in the terminal, and the keypad also has a translucent characteristic in the present invention. Using the LED to send the outline of the subject more clearly during the video call,

The third method has a built-in flash function, which is contained in the terminal equipment except for a video call. In a video call, the user directly operates the flash to turn off the low luminance LED of the keypad. ,

The fourth removable flash function is to attach the flash that is being carried on the video call to the terminal, which may use a separate power source from the terminal, and is configured to receive power from the terminal. By providing a video call using the terminal without difficulty even at night.
