Based on the above real-time photo sharing system, the present invention further provides a real-time photo sharing method, as shown in fig. 5, which is a flowchart of the real-time photo sharing method provided by the present invention, and the method includes:

Before real-time sharing of photos, connection between devices for transmitting data of the photos needs to be carried out. Specifically, before step a, the method further comprises:

the receiver is plugged into a USB port on the PC side. When the first power indicator light is turned on for a long time, the whole machine works normally, and when the first power indicator light is turned off, the first power indicator light represents that a power system or an internal circuit is short-circuited. At this time, it is necessary to check whether the battery needs to be charged or replaced, or to check the internal circuit.

When the first power indicator lamp is on for a long time, a switch key is pressed to automatically start the transmitter, and the transmitter enters a preview mode of the camera according to a preset program. At the same time, the sender makes a re-pairing connection with the receiver according to the last connection record. If the last connection record does not exist, the function key of the search device of the key module in the sender is pressed to carry out pairing connection again, and the color screen module pops up a prompt window with display contents of the name of the receiver and the pairing password needing to be input. After the correct pairing password is input, pairing is successful, and a port GPIO49 of a first MCU chip in the transmitter outputs low level, so that the first working indicator lamp is on for a long time.

After the connection between the devices sharing the photo data transmission is completed, the photographed photo data can be transmitted only by photographing in real time. The step A of taking a picture by using the picture taking transmitter and displaying the picture comprises the following specific steps:

the photographing transmitter is aimed at the photographed object, and a photographing key in the photographing transmitter is pressed. A first MCU chip in the photographing transmitter receives a signal of a photographing key and sends a high level to trigger a CMOS photosensitive photographing element through a GPIO74 port of the first MCU chip to photograph. Meanwhile, GPIO76, GPIO78 and GPIO79 of the first MCU chip 101 respectively send high levels to WRST, WR-CTR and OE ports, respectively start a write pointer server, allow the CMOS to write into the first FIFO buffer memory and trigger the first FIFO buffer memory to work. After the photographing is finished, the image data is transmitted to the first FIFO buffer memory through Y10-Y17 ports of the CMOS photosensitive photographing element. Then, the GPIO75 and GPIO77 ports of the first MCU chip 101 respectively send high level signals to the RRST and RCK ports of the first FIFO buffer 123, respectively, and start the memory read control clock and the pointer server, respectively. The photo data are transmitted to GPIO 80-GPIO 87 ports of the first MCU chip through D0-D7 ports of the first FIFO buffer memory, and the photo data are sent to a second FIFO buffer memory of the first MCU chip.

And displaying the photographed picture in the second FIFO buffer memory of the first MCU chip. The GPIO65 port of the first MCU chip 101 sends a low level signal to trigger the color screen module 106, then the picture data is sent to the Flash of the color screen module for buffering through the GPIO52-GPIO59 of the first MCU chip 101, and the GPIO64 port of the first MCU chip 101 sends a high level signal to the RS port of the color screen module 106 to finally confirm the picture data in the Flash. When the photo is confirmed to be normal, after the confirmation key of the keyboard module 105 is pressed, the GPIO50 of the first MCU chip 101 sends a high level to the CLR port of the color screen module 106 to clear the screen. The first MCU chip 101 displays a prompt message to the color screen module 106 in the same control manner to prompt whether to send the photo data. When the sending key of the keyboard module 105 is pressed, the photo sending program is entered.

At this time, the photographed picture is sent, and the photographed picture is sent from the photographing transmitter to the receiver, wherein the step B is as follows:

b1, the first MCU chip in the photographing transmitter transmits the photographed picture to the communication main module.

In the photo sending procedure, the GPIO44 port of the first MCU chip 101 sends a low level signal to trigger the communication master module 104, and the first MCU chip 101 sends photo data to the Flash of the communication master module 104 through the TXD1 port.

B2, transmitting the photo data to the communication slave module in the receiver.

After the transmission is completed, the RXD1 port of the first MCU chip 100 receives the completion determination signal from the communication master module 104, and then the communication master module 104 transmits the photo data to the communication slave module 202 in the receiver 200 according to the set program. In the data transmission process, the State port of the communication main module 104 sends a low level signal to the first MCU chip 101, and the receiver 200 triggers the GPIO49 port of the first MCU chip 101 to switch between the high level signal and the low level signal and sends the signals to the first work indicator, so that the first work indicator flashes to prompt that the photo data is being transmitted. After the transmission is finished, the State port of the slave module 202 sends a high level signal to the first MCU chip 101, and the GPIO49 port of the first MCU chip 101 is triggered to send a low level signal to the first work indicator, so that the first work indicator is on for a long time to indicate that the transmission is finished.

After the photo data is transmitted from the transmitter to the receiver, the receiver needs to send the photographed photo data to the PC, and the PC receives and displays the photographed photo. The step C is specifically as follows:

the P1.3 port of the second MCU chip sends a low level signal to trigger the communication slave module, meanwhile, the P1.1 port of the second MCU chip sends a high level signal to trigger the USB to serial port module, and the communication slave module sends photo data in the Flash to a PC through TXD3 and RXD3 ports of the communication slave module. In the data transmission process, the communication slave module sends a low level to the second MCU chip, and a P1.5 port of the second MCU chip is switched between a high level signal and a low level signal, so that the second work indicator lamp flashes to prompt that photo data are transmitted. After the transmission is finished, the State port of the communication slave module sends a high level signal to the second MCU chip, and the P1.5 port of the second MCU chip sends a low level signal, so that the second work indicator lamp is on for a long time to indicate that the transmission is finished.

When the system further comprises a projector, the projector is connected with the PC end, and after the PC end receives the photo, the photo is projected to the silver screen through the projector to be displayed, so that the whole photo real-time sharing process is completed.
