Abstract

The disclosure relates to an image transmission device, which includes a central processing unit and a wireless communication module connected thereto, a button, a universal serial bus connector and an internal storage unit. The USB connector is plugged into a computer with portable software, the computer cannot access the internal storage unit, the portable software is copied from an external source to the computer and executed by the computer. The wireless communication module is wirelessly connected to the receiving device. When the button is activated, the button sends a signal to the CPU, and the CPU sends an instruction to the portable software to execute to control the screen mirroring, so that multiple images are transmitted from the computer to the receiving device through the USB connector and the wireless communication module . In this way, security and application diversity can be effectively improved, and the function of one-click screen mirroring can be realized.

Description

technical field [0001] The present disclosure relates to an image transmission device, in particular to an image transmission device and an image transmission method. Background technique [0002] In recent years, various external devices are widely used to assist display projection. For example, when a computer is used to make a presentation, its screen must be mirrored to a projector so that the content displayed on the computer screen can be projected onto the projection screen in real time. Traditionally, D-SUB, DVI or HDMI cables are used to connect computers and projectors for projection. However, this approach is limited to wired connections. [0003] In this regard, image transmission devices have been developed to realize wireless connections between computers and screens / projectors. Traditionally, such image transmission devices usually include an image storage unit for storing related software programs and / or drivers. When the image transmission device is conn...
