Abstract
An image transmission device includes a CPU, and a wireless communication module, a button, a USB connector and an internal storage unit connected with the CPU. The USB connector is inserted into a computer having a portable software. The internal storage unit is inaccessible to the computer. The portable software is copied or downloaded to the computer from an external source and executed by the computer. The wireless communication module is wirelessly connected with a receiving device. When the button is activated, a signal is transmitted to the CPU and a command is transmitted to the portable software by the CPU to execute screen mirroring control, so that images are transmitted from the computer to the receiving device through the USB connector and the wireless communication module. The safety and application diversity are effectively enhanced, and the one-button screen mirroring is realized.
