BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a still image transmission and reception apparatus in which a digital camera technology and a mobile phone technology are combined. In particular, the present invention relates to a digital camera-integrated CDMA, TDMA module-mounted terminal product for integrating a digital camera and a mobile phone and enabling transmission and reception of image information through a mobile phone.

A digital camera has a function of receiving an image image from a lens and converting the image image into a predetermined electric signal, storing the image image in a memory, and displaying the image on an LCD monitor.

Briefly describing the configuration and operation of a general CDMA telephone and a TDMA (TRS terminal) telephone, the control unit controls the overall operation of the mobile phone. The memory stores a certain program controlling the overall operation of the mobile phone and inputs the program during execution. The data to be output and the various data to be processed are stored. The duplexer communicates with the base station via an antenna. When a call is made with a general mobile phone as described above, when there is a need for explanation related to an environment image, a drawing, or a graphic, there may be a lot of troubles with only voice. In addition, as described above, in the case of a digital camera, it is not always carried, so it was inconvenient due to this restriction when image storage transmission for urgent environment image or graphic image is needed.

IMT-2000, which has been ambitiously prepared as a communication device of the 21st century, has been in business because of the huge cost investment. Because of the cost, the economic burden and businessability of consumers are becoming a problem. This is due to technical problems and high terminal cost that cannot appeal to consumers because wireless video service is trying to implement high cost video transmission / reception service. In this regard, the present invention intends to devise a system that implements a wireless image (steel cut) transmission system at a low price at a low cost within four years when IMT-2000 service is popularized.

The PDA using the conventional CDMA mobile phone has been focused on the functions and technologies of the terminal in the wireless Internet service, rather than the implementation of the video transmission and reception beyond the voice of the existing mobile phone, but the simple The purpose of using the still image transmission / receiving terminal device through the CDMA of the TDMA type TRS network and the general mobile phone network serviced by the existing Korea Telecom Powertel is not the wireless Internet service but the low cost optimized system. Can have a system that can send and receive images.

The PDA using the CDMA mobile phone network has been focused on the wireless Internet service rather than implementing the video transmission and reception beyond the voice limit of the existing mobile phone. However, the terminal device is not low-cost wireless Internet service. The optimized system can give existing mobile phone users a system to send and receive images.

In addition, the present invention intends to preoccupy the niche market of second generation wireless communication (CDMA 95A, B, C) and third generation wireless communication (IMT-2000). By clearly distinguishing prices and uses from existing PDA-type CDMA interworking terminals, it is possible to make the first year of image transmission and reception in voice in the Korean CDMA market.

As described above, an object and an object of the present invention are to describe a method and apparatus capable of transmitting and receiving still images through RF wireless networks (CDMA, TDMA) in which popular voice call services are currently made. I would like to.

If the present invention also describes the problem to be achieved on the other side, the user takes the image in the field using this terminal (digital camera + wireless module function) and directly to the specific server of the operator or the e-mail of the desired individual using the wireless network It is possible to provide a method and apparatus that can be transmitted.

Conventional wireless communication devices have transmitted voice data directly to the receiving side in the form of electromagnetic waves or directly to the other party's terminal using a base station through a special modulation method of a service provider.

At present, the needs of consumers in voice signal transmission are not satisfied, and consumers have a need for transmitting and receiving multimedia data. Thus, the form of the present invention can handle not only audio signals but also various data such as still images and various types of document data.

Therefore, the existing user can greatly widen the use of the existing wireless communication device by transmitting and receiving images and various data in addition to voice using the wireless communication device. It can be widely used for forest fire monitoring, illegal fishing at sea, remote wireless medical treatment at hospitals, and disasters caused by natural disasters. However, the existing wireless communication devices are not suitable for various purposes because their functions are stopped in transmitting and receiving voice signals.

When the technical problem to be achieved through the present invention is described more easily, there are products having an external form similar to the present invention when judged in a fragmentary manner, but the present inventors separate the terminal device from the existing similar type through the present invention. Has created a new invention. In other words, if the product of the present invention is appropriately mixed with only the desired features from the characteristics of the existing PDA (personal portable PC), digital camera, personal CDMA (95-A, B, C) mobile phone, TRS radio products A form of terminal function similar to the present invention may be defined.

The apparatus for operating the apparatus of the present invention comprises a data input module unit for receiving an electric image signal generated by an image input apparatus such as a digital camera unit and a process of compressing and encrypting the input electric image signal. There is a transmission / reception section for inputting image data in front of a control unit. Finally, it is a general configuration to include a power control unit for supplying power to the circuit.

In addition, since the data input module portion of the image transmitting / receiving apparatus of the present invention directly receives digital data from a digital camera, analog and digital converters are not required.

In addition, the central processing unit (control unit) of the wireless communication terminal of the present invention constitutes a multimedia file (JPEG, Flash File format) processing by one chip function.

In addition, the wireless communication terminal in the present invention implements an additional function by adding an option to diversify the function of the terminal.

In a simple implementation operation scenario of the wireless image transmission terminal, when an image signal is generated by receiving an image data from an internal digital camera, an electrical image signal is first stored in an internal buffer memory. At the same time, the liquid crystal display displays the image information received from the internal digital camera unit and displays the stored image signal on the LCD screen through the operation of the interface unit.

In this way, the JPEG image of the received electronic image data (Still image) itself chipset is compressed by one frame.

The encryption process involves changing the arrangement of the compressed data in a situation where the compressed dithers are sequentially arranged for one frame. For example, if multiple pieces of compressed data exist for one frame, the data is reordered and transmitted. The change table of the data is generated by the secret code generator, and the change table is mixed by the compressed data and the data code mixer and formatter.

The data generated by the input and compression processing unit is transferred to the transmission and reception unit through the control unit and then enters a wireless transmission standby state through the wireless communication network.

Although the operation of the terminal can not transmit video during voice transmission and reception, if the device notifies the other party of the video transmission and reception operation in advance by a certain signal tone and starts the work, the call may be suddenly disconnected.

Referring to the configuration of the terminal device of the present invention, a liquid crystal display for displaying an image as a digital camera-integrated mobile phone is attached to the front and the camera is located at the upper portion of the terminal. Of course, the digital camera unit and the mobile unit are integrally located in the same case.
