Description of the invention (1) Background of the invention: The present invention is a device for transmitting data, using the image data in & Mutual method between communication devices, especially an image data communication protocol that is self-defining in digital cameras and portable electronic communications. It checks the data for transmission errors and enables the electronic communication camera to receive correct images. data. According to the previous technology, the more the price, the trend, the larger the demand or the data, the more the number of transactions will be easily disturbed. In the process, the error capacity of the round and the receiving technology are: Instead of sending the phone, it is convenient for the data to be transmitted before the internal content of the data is not transmitted during the wired transmission process. It is advisable to design the system to improve its power and receive a large amount of components. Passing the wrong wheel 4 Ren Hexun; In addition, the "wheel way" is not more and more developed and used in communication, as in the "nothing like a call." When calling the phone, the action was wrong, especially because the code is subject to the booming development of its industry. The more people use the mobile phone, especially the planning not only for the trend towards a thin and light market, but also Satisfy the consumer. In this mobile phone, various text messages are pre-set where the user is located. They can communicate through other types of communication. The transmission bandwidth between people and people is in the narrow frequency range. If data is transmitted and received, In the "Pole number" or other external telecommunications signals, it is the "inspection mechanism for the transmission or reception of data. Data transmission is easy to occur. Digital cameras and computers are transmitted and received with high data. The data is transmitted internally. Signal of the component or external
