Abstract: An image transmission method uses image transmission equipment to transmit image signals from an electronic device to a display device, the equipment which includes a base device coupled to the display device, and a peripheral device coupled to an electronic device. The base device wirelessly communicates with the peripheral device. After the electronic device obtains an image transmission program from an outside source existing outside the peripheral device and executes the image transmission program, image signals from the electronic devices can be transmitted to the display device via the peripheral device and the base device.

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.

Abstract: An interactive projection system includes an electronic device, a projection device and an interactive module. The projection device is connected with the electronic device for receiving a first image signal generated by the electronic device and accordingly projecting a first image. The interactive module includes a processing unit, a storage unit connected with the processing unit for storing a calibration data, an image capture unit connected with the processing unit for capturing the first image and a light point image, and a communication unit connected with the electronic device and the processing unit for transmitting an absolute coordinate information computed and generated by the processing unit according to the light point image and the calibration data to the electronic device. An output signal is generated by the electronic device with the absolute coordinate information. Therefore, the present invention avoids the repeating image calibration and reduces labor cost and time cost.
