Title: Method of transmitting pictures by mobile telecommunication device

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a method of transmitting pictures, more particularly to a method of transmitting pictures by a mobile telecommunication device through a picture specification conversion program installed in the mobile telecommunication device, and by using the picture specification conversion table to convert the specification of a picture information into the size complying with the display screen of a model number of a receiver&#39;s mobile telecommunication device, enabling the display screen of the receiver&#39;s mobile telecommunication device to fully show the pictures in the picture information.  
      2. Description of the Related Art  
      After the General Packet Radio Service (GPRS) technology was established, the GPRS technology integrates the independent Global System for Mobile Communication (GSM) and Internet and also adds several data exchange nodes to the current Global System for Mobile Communication. Since the data exchange node has the function of processing packets, so that the Global System for Mobile Communication can be connected to the Internet.  
      Further, the maximum transmission rate between a handset incorporating the General Packet Radio Service technology (hereinafter referred to as GPRS handset) and a base station reaches 160 Kbps, and the data transmission rate of a handset incorporating the Global System for Mobile System (GSM) technology (hereinafter referred to as GSM handset) is 9.6 Kbps. Thus, the transmission rate of the GPRS handset is about 16˜17 times faster than that of the GSM handset, which is a large increase. The speed 160 Kbps is also 2˜3 times faster than the dialup modem speed 56 Kbps. General personal computers can use the transmission rate of 56 Kbps to browse the text and graphics on Internet. Of course, the GPRS handset can concurrently send out multimedia information including sound, pictures and text. For example, a GPRS handset is used to send multimedia messaging service (MMS), and MMS is called “Color Information” by China Mobile Company or “Color Mobile Audio and Picture Message Service” by Taiwan Mobitai Communications. As implied by its name, multimedia messaging service (MMS) can transmit contents of multimedia information including various text information, black and white or color graphic files, sound (including ring tone, chord ring, a record of sound, or even a use&#39;s voice recorded by the handset and differs according to different supporting file formats). Besides transmitting rich contents, the MMS also inherits the advantages of the traditional short message for sending multimedia short messages to opposite parties or receiving multimedia short messages from one&#39;s handset or email address. Compared with the short message service (SMS), MMS can transmit larger volume of information in a richer and more colorful expression form.  
      However, since the size of display screen of the GPRS handset of each brand or different models of the same brand is different. If a GPRS handset uses MMS to directly send out pictures without making any editing, the receiver&#39;s handset may have the following problems when displaying the received pictures:  
      (1) The size of the pictures sent by the sender&#39;s handset is larger than the size of display screen of the receiver&#39;s handset. As a result, the edge of the picture goes beyond the edge of the display screen, and the receiver&#39;s handset cannot show the picture in full.  
      (2) The size of the pictures sent by the sender&#39;s handset is smaller than the size of display screen of the receiver&#39;s handset. As a result, some dark edges are produced between the edge of the display screen and the edge of the picture.  
      Therefore, fully showing a picture transmitted from a sender&#39;s handset onto the display screen of a receiver&#39;s handset demands immediate attention and solution.  
     SUMMARY OF THE INVENTION  
      In view of the shortcomings of the prior art, the inventor of the present invention conducted extensive researches and experiments, and developed a method of transmitting pictures through a mobile telecommunication device in accordance with the invention.  
      The primary objective of the present invention is to provide a method that installs a picture specification conversion program in a mobile telecommunication device, and the picture specification conversion program includes a picture display conversion table, and the picture display conversion table includes a plurality of fields for inputting model numbers of different mobile telecommunication device and picture specifications corresponding to the model numbers, so that when the mobile telecommunication device sends a picture information to a receiver&#39;s mobile telecommunication device, the mobile telecommunication device uses the picture specification conversion table to obtain the picture specification of the receiver&#39;s mobile telecommunication device, and then converts the specification of the picture information into the size complying with the display screen of the receiver&#39;s mobile telecommunication device, and sends the converted picture information out. Therefore, the display screen of the receiver&#39;s mobile telecommunication device can fully show the pictures in the converted picture information.
