Description

Hands-free video call device for vehicle {A PICTURE TELEPHONE CELL DEVICE OF HANDS FREE IN VEHICLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle handsfree, and more particularly to a vehicle handsfree video call apparatus capable of video calling.

In the radio broadcasting communication method, an antenna is installed as high as possible to cover a large area in order to increase transmission power. At this time, the same frequency as the radio frequency used in the area cannot be used unless it goes farther to avoid interference. In the case of a communication type such as an automobile telephone that requires one frequency for one call, there is a limit to the frequency that can be used and the number of communication lines that can be used simultaneously.

The cellular method is also called a small zone method, and is a method of obtaining a wide service area by connecting a large number of wireless zones in which the transmission power is reduced and the area where radio waves can reach. According to the above method, since the frequencies used in one wireless zone can be used in one neighboring wireless zone, the number of external frequencies that can be used as the entire service area can be increased.

Therefore, as described above, the conventional mobile phone system can transmit and receive a voice signal while moving, thereby enabling a telephone call from anywhere.

In particular, a telephone call using a vehicle hands-free has been possible in the related art for safe driving while moving in a vehicle.

However, as video telephony becomes possible with the progress of technology, the current hands-free has a problem that video calls are impossible while moving to a vehicle.

Accordingly, an object of the present invention is to solve the above problems, and to provide a hands-free video call device for a vehicle that allows video calls even while the vehicle is moving.

FIG. 1 is a block diagram illustrating a video communication device of a vehicle handsfree according to the present invention, wherein a handsfree including a voice processing unit 1100 capable of processing voice transmission and reception to enable a telephone call to the mobile phone 2000 while moving a vehicle ( 1000); A microphone (100) connected to the hands-free (1000) for converting voice into an electrical signal and transmitting the voice signal; In the vehicle hands-free comprising a speaker for converting the received audio signal to an audible frequency to convert the voice to audible audio for the driver, the image processing unit 1200 for processing to transmit and receive the image by the mobile phone (2000) )Wow; A main processor 1300 for controlling the operation state of the audio processor 1100 and the image processor 1200 is further provided.

The image processing unit 1200 may include a camera 300 which photographs an image and transmits the image to the image processing unit 1200 as a predetermined electric signal; It is connected to the monitor 400 receives the image signal received from the image processing unit 1200 and outputs it for the driver to see.

The image processing unit 1200 may further include a transmission image signal processing unit 1210 for processing an image signal photographed and transmitted by the camera 300 and outputting the predetermined image signal to the mobile phone 2000 as a predetermined signal; The video signal and text signal received from the mobile phone 2000 is input to the user to view the image signal and text signal processing so that the user can see the image signal processor 1220 is output to the monitor 400.

The main processor 1300 includes an input unit 1310 provided with a call button for selecting a video call according to a user's intention, and a keypad for selecting a phone number and automatic dialing; To control video call transmission and reception by a program set according to a signal selected and input by the input unit 1310, to separately control a received video signal and a text signal, and to store a predetermined input signal and a received text signal. A microcomputer 1320 for outputting a predetermined control signal; In synchronization with the control signal output from the microcomputer 1320, the phone number input by the input unit 1310 and the text message received by the received image signal processor 1220 are stored, and the stored phone number and text message are stored. The memory unit 1330 is output.

The operation of the vehicle hands-free video call device having the above-described configuration will be described.

The mobile phone 2000 connected to the hands-free 1000 while driving the vehicle always transmits to the hands-free 1000 that it is in a reception standby state.

Accordingly, the microcomputer 1320 included in the main processor 1300 of the hands-free 1000 checks whether a reception state is received by the mobile phone 2000.

Subsequently, when a "call" signal is input from the mobile phone 2000, the microcomputer 1320 included in the main processor 1300 of the hands-free 1000 may output the audio (not shown) until the call is completed. Block temporarily.

Subsequently, the microcomputer 1320 included in the main processor 1300 of the hands-free 1000 receives voice signals and video signals received from the mobile phone 2000 from the voice processor 1100 and the image processor 1200, respectively. The signal is processed into a received image signal and output to the speaker 200 and the monitor 400.

The received voice signal may be processed by the received voice signal processor 1120 in the voice processor 1100 of the hands-free 1000 and output to the speaker 200 as a predetermined electric signal so that the user can hear the voice of the other party.

In addition, the received video signal may be processed by the received video signal processor 1220 in the image processor 1200 of the hands-free 1000 and then output to the monitor 400 so that the user may view an image of the other party's caller.

At this time, the microcomputer 1320 of the hands-free 1000 main processor 1300 determines whether a text message is included in the received video signal.

When it is determined that the text message is included in the received video signal, the microcomputer 1320 outputs the received text message to the monitor 400 and temporarily stores the received text message in the memory 1330.

The voice of the user according to the call of the mobile phone 2000 is transmitted by the microphone 100 to the transmission voice signal processing unit 1110 of the voice processing unit 1100 as a predetermined electric signal, and the image of the user is the camera 300. Is taken and transmitted to the transmission image signal processing unit 1210 of the image processing unit 1200 as a predetermined image signal.

The transmission voice signal processing unit 1110 of the audio processing unit 1100 processes a predetermined electric signal transmitted from the microphone 100 as a voice signal and is transmitted to the mobile phone 2000, and at the same time, the transmission image of the image processing unit 1200. The signal processor 1210 processes and transmits a predetermined video signal transmitted from the camera 300 to the mobile phone 2000.

The mobile phone 2000 receives a signal transmitted from the voice processor 1100 and the image processor 1200 of the hands-free 1000 and transmits the signal to the base station as a cellular signal having a predetermined frequency.

Subsequently, the microcomputer 1330 of the hands-free 1000 main processor 1300 returns the output of the audio (not shown) normally when it is determined that the user "ends a call."

The hands-free 1000 includes an input unit 1310 having a "call" and "call completion" buttons and a "number" button for inputting a telephone number, so that a predetermined signal is input from the input unit 1310. The microcomputer 1320 pauses and restores the output of the audio (not shown).

Therefore, the telephone number can be transmitted using the hands free 1000 according to the user's willingness to transmit, and furthermore, the automatic dial and speed dial transmission can be performed without using the mobile phone 2000.

As described above, the hands-free video call device for a vehicle according to the present invention can perform safe driving as the video call is possible while the vehicle is moving, can feel more realistic due to the video communication, and can pursue the luxury of the vehicle. At the same time, there is an effect that can meet the needs of the user.
