In addition, time division duplexing is a duplexing method of a communication system for separating reception and transmission channels in a mobile communication system. Mobile communication is currently developing to the third generation, and china filed the third generation draft of mobile communication standards (TD-SCDMA) in 6 months 1997, and its features such as TDD mode and new technology of smart antenna are highly evaluated and become one of three main candidate standards. TDD mode has not been emphasized on the whole in FDD mode in first and second generation mobile communication systems. However, due to the need for new services and the development of new technologies, and many advantages of the TDD mode, the TDD mode will be increasingly emphasized.
The working principle of time division duplex is as follows: TDD is a duplex scheme of a communication system for separating a reception channel and a transmission channel (or uplink and downlink) in a mobile communication system. In the TDD mode mobile communication system, the receiving and transmitting are in different time slots of the same frequency channel, namely carrier, and the receiving and transmitting channels are separated by using the guaranteed time; in the FDD mode, the receiving and transmitting are performed on two separate symmetric frequency channels, and the receiving and transmitting channels are separated by a guaranteed frequency band.
The characteristics and communication benefits of mobile communication systems employing different duplex modes are different. The uplink and downlink channels in the TDD mode mobile communication system use the same frequency, and thus have reciprocity of the uplink and downlink channels, which brings many advantages to the TDD mode mobile communication system.
In TDD mode, the transmission of information in uplink and downlink can be performed on the same carrier frequency, i.e. the transmission of information in uplink and the transmission of information in downlink are realized by time division on the same carrier.
Finally, it should be noted that each functional device in the embodiments of the present invention may be integrated into one processing device, or each device may exist alone physically, or two or more devices may be integrated into one device.
The functions, if implemented in the form of software-enabled devices and sold or used as a stand-alone product, may be stored in a computer-readable storage medium. Based on such understanding, the technical solution of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the steps of the method according to the embodiments of the present invention. And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk or an optical disk, and other various media capable of storing program codes.

8. The multi-functional ride defense warning method of claim 7, characterized in that the method further comprises:
and the use range comparison device is connected with the parameter extraction device and used for sending out a first driving signal when the current white balance value is out of a preset white balance numerical range, and also used for sending out a second driving signal when the current white balance value is within the preset white balance numerical range.
9. The multi-functional ride defense warning method of claim 8, characterized in that:
the range comparison device comprises a memory and a comparator, the memory is used for storing the preset white balance value range, and the comparator is respectively connected with the memory and the parameter extraction device;
wherein, in the range comparing device, the preset white balance numerical range is defined by a preset white balance upper threshold value and a preset white balance lower threshold value.
10. The multi-functional ride defense warning method of claim 9, further comprising:
using a field compensation device respectively connected to the distance detection device, the range comparison device and the parameter extraction device, for performing, upon receiving the first driving signal, a white balance compensation process on the guide filtered image based on the current white balance value to define a white balance value of the processed image within a preset white balance value range;
the field compensation device is also used for outputting the processed image serving as a field compensation image to the distance detection device in place of the guide filtering image;
and the field compensation device is also used for outputting the guide filtering image to the distance detection device as a field compensation image instead of the guide filtering image when receiving the first driving signal.
