Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable radio telephone apparatus, and more particularly to an image transmission communication terminal that realizes efficient and simple image transmission.
[0002]
[Prior art]
As a conventional technique, image transmission is performed during a call, and the transfer rate of a portable terminal is at most 64 Kbps. In addition, portable communication terminals are becoming smaller and lighter, and there are few cases in which high-definition still images and moving images need to be transmitted. Since the video of the caller is displayed on the terminal by simple one-shot image transmission (either a still image or a moving image), the convenience of the call is increased and it contributes to the acquisition of the user. In addition, the advancement of image processing technology enables image compression / decompression processing with simple hardware.
[0003]
[Problems to be solved by the invention]
However, there is no mobile terminal that completes image transmission during a call, and image transmission performed during a call has a problem in that the quality of the image has to be deteriorated.
[0004]
In addition, since the image is transferred during the call, the quality of the call must be impaired, and the capacity of the data communication has to be reduced because the image is transferred during the call.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide an image transmission communication terminal that realizes efficient and simple image transmission without losing the quality of a call because image transmission processing is completed during a call.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention described in claim 1 of the present invention is a mobile phone device capable of transmitting image data, wherein a caller's side during a call or call connection process or a call process is provided. In the caller-side communication terminal that captures an image, an image capturing unit that is built in a direction perpendicular to the dial surface, a video capturing unit that captures a video of the caller using the image capturing unit, and a captured image An image processing means for image processing data according to a communication data channel capacity and a means for transmitting the image processed data to a partner communication terminal , wherein the image capturing means It is characterized by capturing the video of the caller.
[0011]
According to the above configuration, since an image is transmitted using a vacant channel that is being called, an image transmission communication terminal that transmits an image of a caller without degrading voice quality during a call is provided.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0013]
FIG. 1 is an external view showing the configuration of a simplified image transmission communication terminal according to the present invention, and FIG. 2 is a block diagram showing the configuration of the image transmission communication terminal of the present invention.
In FIG. 1, an image transmission communication terminal 1 includes a solid-state imaging device for photographing a user's face and capturing an image, an optical system such as a lens, and a small imaging unit 2 that is a device for capturing a self-portrait. It is provided at the upper front. Also, an RF signal transmission / reception antenna 3, a speaker 4 that converts the other party's voice signal into voice, a liquid crystal display unit 5 that displays the other party's image, a key operation unit 6 that performs dialing, transmission, address registration, etc. A microphone 7 for converting the own voice into an audio signal is provided.
[0014]
In FIG. 2, a baseband processing unit 11 performs digital processing necessary for communication. The RF processing unit 12 is an interface between a baseband signal and a radio band signal. The speaker 13 converts the other party's voice signal into voice. The speaker interface 14 converts the other party's voice signal into an analog signal. The microphone 15 converts the voice of the speaker into a voice signal. The microphone interface 16 amplifies the own voice signal and converts it into a digital signal. The man-machine interface 17 is a signal processing unit such as a button or a volume. The imaging unit 18 captures a self-image. An image processing unit (encoder) 19 compresses the self-image data. The liquid crystal display unit 20 displays the partner image. The image processing unit (decoder) 21 decompresses the partner image data.
[0015]
Next, the operation of the image transmission communication terminal in the usage state will be described.
[0016]
First, in the image transmission communication terminal 1 on the transmission side, the face of the caller is displayed by the small imaging unit 2 built in the vicinity of the dial panel while the other party number is dialed by the key operation button 6 or at the same time the call button is pressed. Import as an image. At this time, the imaging unit 2 is installed so as to be perpendicular to the panel surface. That is, generally speaking, when dialing, the caller tends to naturally point the dial panel surface toward his / her eyes or face, so if the direction of the imaging unit 2 is set to be perpendicular to the dial panel surface, It is enough.
[0017]
A normal wireless connection sequence is started at the same time as the call button is pressed. At this time, using the idle time during the call connection process or the call process, the captured image data is subjected to image processing according to the communication data channel capacity and transmitted to the partner terminal.
[0018]
【The invention's effect】
As described above, the image transmission communication terminal according to the present invention completes image transmission during a call, so that the call quality is not deteriorated. Moreover, since it is a simple image transmission, advanced hardware and software are not required.
[0019]
In addition, since image transmission processing such as compression is performed during wireless connection processing, call quality is not deteriorated. Further, since the decompression process on the receiving side is performed during the incoming call response process, there is an effect that the call quality is not affected.
