Since the signal processed by the host of the PC is a digital signal, and the CRT display can only display the image of the analog signal, a digital/analog signal converter is arranged at the output of the host to convert the digital signal of the host to analog. The signal is displayed for the CRT ^ display. Early projectors also used CRT for projection imaging'. Therefore, when the projector receives the analog signal from the host, it can be projected without signal conversion. [0003] With the development of projectors, projectors began to adopt LCDCLiquid Crystal Display) or DMD (Digital Micromirror Dev ice Digital Micromirror) replaces the CRT for projection, and the processing signal in the projector is also changed from analog signal to digital signal. The projector at this time is called a digital projector. However, since the signal output from the majority of consumers' β PC mainframes is still analogous, the manufacturer has set up an analog/digital converter for the signal access terminal of the digital projector to make the digital projector and the PC. Inter-Signal Compatibility [0004] With the development of wireless digital communication, wireless digital communication technology has begun to be applied to the projection field. Manufacturers have developed a wireless receiver for use with existing digital projectors. The wireless receiving device includes a wireless transceiver and a digital/analog signal converter. The wireless transceiver is configured to receive the wireless digital signal transmitted by the PC, and extract the wireless digit 096135475 Form No. A0101 Page 4 / 14 pages 1003118418-0 100 April 07 Shuttle Replacement Page 1353179 Signal Digital image information. The digital/analog signal converter is configured to convert the digital image information into analog image information. The analog image information is transmitted to the digital projector via an interface. The digital projector converts the analog image information into digital image information through an analog/digital signal converter, and then performs projection display. [0005] The above-mentioned wireless digital projection device first converts digital information into an analog signal in one projection process, and then converts the analog signal into digital information, and then delivers it to the DSP for processing. Due to the secondary signal conversion, the noise in the image is increased, resulting in a decrease in imaging quality. SUMMARY OF THE INVENTION [0006] In view of the above, it is necessary to provide a wireless digital projection apparatus and method that effectively improve imaging quality. [0007]

The processing module 3 is configured to directly acquire the image information and perform format conversion on the image information that is not supported by the wireless projection device 100. The processing module 30 is a DSP (Digital Signal Processing) that acquires the image information extracted by the wireless receiver 2 and determines whether the wireless projection device 100 supports the image information. The format 'is whether the wireless projection device 100 can project the image information. When the wireless projection device 1 cannot project the image information, the processing module 30 performs format conversion on the image information, so that the wireless projection device 100 can project the image information. [0015] In the embodiment, the processing module 30 acquires the image received by the wireless receiver 20 as an example, and the wireless projection device supports an image of the BMP format instead of Support for images in JPG format. However, since the image happens to be in the JPG format, the processing module 30 formats the image and converts it into an image of the BMP format. [0016] It can be understood that a first buffer can be set between the wireless receiver 10 and the processing module 30. The first buffer is used to buffer the image information extracted by the wireless receiver 10. [0017] It can be understood that the present invention is not limited to converting an image into a fixed format as long as its function is the same as the present invention or All similarities should be covered by the scope of the present invention. 096135475 Form No. A0101 Page 7 of 14 1003118418-0 1353179 [0019] [0020] [0023] [0023] [0023] 096135475 100 April 2010 Correction page can be understood, said The processing module 3 can also adjust the saturation, contrast, brightness, and sharpness of the image information. The projection module 40 is configured to project the processed image information. The image of the processing module 3 is processed by the processing module 3 in the embodiment, and is the image to be format converted by the processing module 3 Projection. It can be understood that a first buffer may be disposed between the processing module 30 and the projection module 4 for buffering the processed image information of the processing module 3 . It can be understood that the wireless projection device 1 of the present invention can also be provided with a conventional VGA (Video Graphics Array) interface to connect with an external electronic device to receive image information of analog signals, and set a corresponding one. The analog/digital converter converts the image information of the analog signal into image information of the digital signal, and then delivers the image information of the digital signal to the processing module for processing. Please refer to FIG. 2 for the wireless The projection method flow chart of the digital projection device includes the following steps: Step S11: receiving wireless digital information, and extracting image information in the wireless digital information. The wireless receiver 20 receives a digital information transmitted from an external electronic device, and unpacks the digital information to extract image information. The digital information can be transmitted by infrared data transmission technology, transmitted by Bluetooth technology, or transmitted over a wireless network.

In the embodiment, the processing module 30 acquires the image information extracted by the wireless receiver 10, and determines whether the wireless projection device supports the image information. [〇〇25] _ It can be understood that a support format < list is stored in the wireless projection device 100, and the wireless projection device 100 can be judged by looking for the format of the image information in the list. Whether to support this image information. A [0〇26] + φ $^S21 : If not supported, the image information is format converted, and the image information is projected and displayed. In this embodiment, the location@module 30 converts the image information into a file format supported by the wireless projection device 1 , and then the projection module 40 displays the image information after the format conversion. . [0027] It can be understood that in the step S15 and the step S21, a step of mediating parameters such as saturation, sharpness, contrast, and brightness of the image information may be added. [0028] Step S23: If supported, the image information is directly displayed and displayed. In the embodiment, the projection module 40 acquires the processed image information of the processing module 30, and directly compares and displays the image information. The wireless projection device directly has a wireless receiver, and the wireless After receiving the wireless digit information, the receiver extracts the image information from the wireless number >& information, and the money is directly delivered to the processing module for subsequent processing. Therefore, there is no need to convert between the digital signal and the analog signal.
