There is an advantage.

Hereinafter will be described in detail with reference to the accompanying drawings, a preferred embodiment of a method for transmitting an image by fax in the present invention mobile phone.

2 is an explanatory diagram of an image transmission method using the present inventors fax in addition to the existing service.

First, a mobile phone 200 equipped with a small camera 210 and a display unit 212 is presented. The small camera 210 is installed on one side of the mobile phone 200. The small camera 210 performs image capturing and is implemented as a CCD camera or a CMOS camera. In addition, a driving chip (not shown) is provided inside the mobile phone 200, and the driving chip (not shown) controls image capturing and image transmission. The display unit 212 is installed at one side of the mobile phone 200. The display unit 212 displays an image photographed by the small camera 210. The image transmitted from the mobile phone 200 is transmitted to the mobile communication base station 230. The mobile communication base station 230 is provided with a modem pool (IWF) interworking function (232). The modem pool 232 converts the digital signal transmitted from the mobile phone 200 into an analog signal. The base station 230 is connected to the user's fax 250 via a public switched network (PSTN). The fax 250 receives image data sent from the mobile phone 200.

The following describes an operation process for the method of transmitting an image to a fax in the mobile phone of the present invention having the configuration as described above.

3 is a flow chart of the data flow from a mobile phone to a fax receiver.

First, the user photographs an image to be transmitted to the mobile phone 200 equipped with the small camera 210 (step 310). The image photographed in step 310 is displayed on the display unit 212 of the mobile phone 200. Shooting of the image is controlled from the driving chip (not shown).

After performing step 310, when the user wants to transmit the generated image to the fax 250, the user dials the fax number (step 312). A call is set up by dialing.

After performing step 312, the image generated by step 310 is converted into a black and white image format suitable for receiving by fax (step 314). Step 314 is a function that does not exist in the existing fax service option is implemented in the present invention through the present invention.

Step 314, which is a black and white image conversion step, is performed by a fax program on an application layer of a mobile phone. Looking at the fax program in detail, the program is executed in a core chip (most of which is actually an ARM core) inside the mobile phone, and is controlled by a modem control unit (MCU). In addition, the monochrome image conversion may be performed by converting an image photographed from a camera into a compressed file such as JPEG and then using a digital signal processor (DSP) inside the modem chip.

After performing step 314, the data converted in step 314 is transmitted to the mobile communication base station 230 using the fax service option built in the mobile phone 200 (step 316). The fax service option is one of the service option functions embedded in the mobile phone, which is responsible for determining what kind of call is a call sent when a call is transmitted from a base station or a mobile phone in a CDMA mobile communication system. These service options have a 16-bit data value and are responsible for the service of voice, text and fax for each service number. Step 316 is also controlled by a driving chip (not shown).

After performing step 316, the base station exchange 230 converts the image transmitted by the fax service option into a fax format (step 318). Specifically, the base station 230 recognizes that the call sent from the mobile phone 200 is fax data and opens a path to the IWF 232. The IWF 232 converts the received digital data into an analog signal that can be received by the fax 250 receiver using an analog modem.

After performing step 318, the data converted according to the fax protocol in step 318 is transmitted to a public switched network (PSTN) fax number (step 320). Step 320 is performed by the IWF modem 232.

Finally, the recipient receives the image through the fax 250 receiver connected to the public network when there is a call with the fax number.

The above embodiment is merely one embodiment of the technical idea of the present invention, and of course, other modifications can be made within the technical idea of the present invention.
