Transmitting and receiving signal synthesizing unit 22, a receiving unit 23 for low frequency processing the radio signal received through the antenna 21, and the audio signal of the signal processed by the receiving unit 23 is separated by the user A reception signal processor 24 which transmits to the speaker 31 so that it can be heard and transmits various data except for the sound line signal to the central processing unit 25, various data and antennas received from the reception signal processor 24; 21, a central processing unit 25 for processing various types of data to be transmitted, and processing such that various data input from the central processing unit 25 and audio signals input from the speaker 30 can be transmitted to the transmitting unit 27.Transmitting signal processing section 26, the transmission section 27 for making a high frequency of the standard so that the various signals processed by the transmission signal processing section 26 through the antenna 21, and the central processing section 25 Memory 28 for storing various types of information for processing signals, and a screen display unit for enabling video calls through video signals received through the antenna 21 and for displaying various other data. (29), the microphone 30 to amplify the user's voice signal to be heard by the other party's receiver, and the other party's voice signal processed and sent by the reception signal processor 24 so that the user can hear the other's voice signal. Is the image signal detected by the speaker 31, the key input unit 32 for inputting various information (SEND, END, # 1 to # 9, etc.) so that the user can use the telephone, and the receiver 23 of the terminal? Accordingly, the terminal use state detection unit 33 detects whether the current terminal use state is a video call state or a general telephone state and transmits the detected state to the central processing unit 25. According to the detection, the volume of the user input and output through the microphone 30 and the speaker 31 is automatically adjusted.

In this case, the reception signal processing unit 24 outputs voice current signals having different levels according to the terminal use state detection result of the terminal use state detection unit 33. The first and second speakers 31a and 31b output the same. It consists of.

The image display unit 29 is composed of a flat panel display such as a liquid crystal display (LCD) or a plasma display panel (PDP).

Since the method of using a general telephone through an antenna is the same as in the conventional method of using the mobile terminal for video of the present invention, description of the operation when using the general telephone will be omitted.

Subsequently, the method for controlling the call volume of the present invention is as follows.

The use state detection unit 33 of the image mobile terminal of the present invention uses a software method or a hardware method to detect the use state of the terminal.
