Mutual data transmission method between digital camera and portable electronic communication equipment

Abstract

The present invention provides a method of data mutual transmitting between the digital camera and the portable electronic communication device, which utilizes a self-defined image data communication protocol to send a command packet created by the portable electronic communication device to the digital camera to let the camera convert the image data stored on it to be at least above one rollback packets according to this command packet by utifizing this communication protocol, and then to transmit them back to the electronic communication device to let the electronic communication device carry out the error checking for the checking column position contained in the rollback packet by utilizing this communication protocol to ensure the electronic communication device receiving the correct image data from the digital camera.

Description

Technical field [0001] The present invention relates to a method for mutual data transmission between a digital camera and a portable electronic communication device, in particular to a method of using a self-defined image data communication protocol between the digital camera and the portable electronic communication device to communicate data during the transmission process. The image data is checked for data errors, so that the electronic communication device can receive correct image data from the digital camera. Background technique [0002] In recent years, due to the vigorous development of the communications industry, the price of mobile phones has become cheaper and cheaper, and more and more people are using mobile phones. In particular, the design and development of mobile phones have not only moved towards the market trend of light, thin, short Moving forward, its functions and uses are planned to meet the needs of consumers and continue to improve. For example, in th...

[0003] At present, the transmission capacity of traditional mobile phones is in the narrow frequency range. If the capacity of a piece of data is too large, the data is easily affected by the activation signal of its internal components or other external telecommunication signals during the transmission and reception process. Interference caused by data transmission errors, especially, in the process of data transmission or reception, because there is no inspection mechanism for signal coding, data transmission errors are very easy to occur; in addition, because the general digital camera and computer are based on High-capacity wired transmission method for data transmission and reception. During the process of data transmission and reception, the data will not be interfered by the actuation signal of its internal components or other external telecommunication signals. The data transmission and reception status is very stable. Therefore, the data transmission and reception between a general digital camera and a computer can easily complete the data transmission of tens to hundreds of K (thousand) bytes, although no other signal coding inspection mechanism is added.

[0004] Since, on traditional mobile phones, the high-capacity transmission method between general digital cameras and computers cannot be directly used, if you want to increase the function of receiving image data from digital cameras, it is necessary to address the data transmission between digital cameras and mobile phones. In order to effectively solve the important issue of transmitting high-capacity image data, make mobile phones meet the goal of multi-functional development
