Embodiment Construction

[0012] Such as figure 1 Shown is a functional block diagram of the wireless projection device 100 provided by the embodiment of the present invention. The wireless projection device 100 includes a wireless receiver 20 , a processing module 30 and a projection module 40 .

[0013] The wireless receiver 20 is used for receiving wireless digital information, and extracting image information from the received wireless digital information. The wireless receiver 20 can receive a digital message from an external electronic device. The digital information can be transmitted through infrared data transmission technology, bluetooth technology, or wireless network.

[0014] It can be understood that in the existing wireless transmission technology, the transmitted data will be packaged, but in the wireless projection device 100 in this embodiment, the wireless receiver 20 has the function of unpacking. In this embodiment, for example, Bluetooth technology is used to transmit data. Aft...

Abstract

The invention provides a wireless projecting apparatus which comprises a wireless receiver, a processing module and a projecting module, wherein the wireless receiver is used for receiving wireless digital information and extracting image information in the received wireless digital information; the processing module is used for directly capturing the image information and performing format conversion for the image information which is not supported by the wireless projecting apparatus; and the projecting module is used for projecting the image information after being processed. The wireless projecting apparatus does not need to convert between digital signals and analog signals so as to reduce the probability of noise and improve the imaging quality. In addition, the invention also provides a wireless projecting method for the wireless projecting apparatus.

Description

technical field [0001] The invention relates to a wireless digital projection device and method. Background technique [0002] Early PC (Personal Computer) monitors used were CRT (Cathode Ray Tube cathode ray tube) monitors. Since the signal processed inside the mainframe of the PC is a digital signal, and the CRT display can only display images of analog signals, a digital / analog signal converter is installed at the output end of the mainframe to convert the digital signal output by the mainframe into an analog signal for the CRT The display shows. Early projectors also used CRT for projection and display, so when the projector receives the analog signal from the host, it can project without signal conversion. [0003] With the development of projectors, projectors began to use LCD (Liquid Crystal Display) or DMD (Digital Micromirror Device) instead of CRT for projection, and the processing signal in the projector also changed from analog to digital. signal, the projecto...
