Description

541831

In particular, the present invention relates to a digital imaging system which can be remotely monitored. 5-2 Background of the Invention: A general digital camera converts its digital image: Ji Yi, or—external memory (externalmemc) rycard), K = -connected peripheral display device, such as a TV or personal computer, for use The computer displays the glory view and stores it in the memory of the digital camera. M: If you want to print out the daytime image, the image data stored in the digital camera can be transferred to a personal computer, and the image data will be output to an application software— Printer. When the digital camera that wants to transmit the digital camera needs a central processing unit that manipulates the surface, it is then transmitted to the remote hardware through a wireless communication network. The operating specifications are not compatible with the image data captured by the median camera. Only the card is received, but cannot be directly sent to the communication network. The video data of the digital camera is sent to a remote connection device. The shadow data is transmitted to a communication interface through a wired communication network or connected device. However, @, digital camera = the hardware operating specifications of the processor, the number ^ is flash memory or an external memory sergeant processor. Therefore, if you want to transfer data to a remotely connected device
