Detailed Description
Embodiments of the real-time camera resolution adjustment system and method of the present invention will be described in detail below.
The resolution, also called resolution, can be classified from two directions, display resolution and image resolution.
The display resolution (screen resolution) is the precision of the screen image and refers to how many pixels can be displayed on the display. Since the dots, lines and planes on the screen are all composed of pixels, the more pixels the display can display, the finer the picture is, and the more information can be displayed in the same screen area, so that the resolution is a very important performance index. The whole image can be thought of as a large chessboard, and the resolution is expressed by the number of all the longitude and latitude intersections. Under the condition of a certain display resolution, the smaller the display screen is, the clearer the image is, on the contrary, when the size of the display screen is fixed, the clearer the image is when the display resolution is higher. The image resolution is the number of pixels included in a unit inch, and its definition is closer to the definition of the resolution itself.

Next, the detailed structure of the real-time camera resolution adjustment system of the present invention will be further described.
In the real-time camera resolution adjustment system:

Meanwhile, in order to overcome the defects, the invention also provides a real-time camera resolution adjusting method, which comprises the following steps: a real-time camera resolution adjustment system is used to adjust the resolution of subsequently captured images when a roller coaster body is present in the images captured by the track camera to facilitate subsequent capture of the guest's mood.
Additionally, the network input interface may be a frequency division duplex communication interface. Frequency division duplexing means that uplink and downlink transmissions are made on different frequencies, respectively. In the first and second generation cellular systems, FDD technology is basically used for duplex transmission. In particular, in the first generation cellular systems, since continuous baseband signals are transmitted, duplex uplink and downlink channels must be provided using different frequencies. In the first generation cellular systems, in which FDD is used for continuous information transmission, frequency synthesizers for generating different carrier frequencies are required at both the transmitting and receiving ends, and a duplex filter for preventing the transmission signal from leaking to the receiver is required at the receiving end. In addition, in order to facilitate the fabrication of the duplexer, a certain frequency interval is required between the transmission and reception carrier frequencies. In the second generation of systems such as GSM, IS-136 and IS-95, FDD technology IS also used. In these systems, since the information is transmitted in time slots, the transmission and reception can be performed in different time slots, and the transmission signal of the mobile station or the base station does not interfere with the receiver. So, despite the FDD technique employed, no expensive duplex filters are required.
The FDD mode is characterized by receiving and transmitting in two symmetric frequency channels separated (190 MHz between uplink and downlink frequencies), and separating the receiving and transmitting channels by guard bands.
By adopting the technologies of packet switching and the like, the bottleneck of the second generation development can be broken through, the high-speed data service can be realized, the frequency spectrum utilization rate can be improved, and the system capacity can be increased. FDD must provide third generation services using paired frequencies, i.e., within a bandwidth of every 2x5 MHz. The mode can fully utilize the uplink and downlink frequency spectrums when supporting the symmetric service, but the frequency spectrum utilization rate is greatly reduced (about 40 percent of the frequency spectrum utilization rate is reduced due to low uplink load) when the asymmetric packet switching (Internet) works, and in this regard, the TDD mode has incomparable advantages compared with the FDD mode.
