In the above embodiment, the circuit connection structure of the display and the camera module 2 as shown in fig. 11 may specifically operate according to the following principle:

first, the display main board 13 powers on the single chip 27 to power on and initialize the single chip 27, and the single chip 27 controls the control end of the MOS transistor 293 to be conducted to power the ISP image signal processor 26 through the GIPO to initialize the ISP image signal processor 26, and communicates with the ISP image signal processor 26 through the UART module, as shown in fig. 12 and 13.

Specifically, the specific process of power-on initialization may be that after the single chip 27 is powered on, a clock, a register, a GPIO port, an I2C module, a UART module, an interrupt module, and the like are initialized. Subsequently, the single chip 27 controls the MOS 293 control end to be conducted through the GIPO to supply power to the ISP, and sets the acceleration sensor to operate in the interrupt mode through the I2C module. After the ISP is powered on, the DDR, Flash, GPIO, USB module, UART module, etc. are initialized to wait for receiving the command of the motherboard 13 and the command of the single chip 27UART module.

Then, the single chip microcomputer 27 initializes the acceleration sensor by addressing I2C (SCL and SDA), and the single chip microcomputer 27 executes an acceleration sensor interrupt processing flow.

Specifically, when the user turns the camera module 2 to the horizontal direction (the included angle between the lens bearing base 21 and the non-light-emitting side of the display screen 11 is 90 degrees), the acceleration sensor sends an interrupt signal INT1 to the single chip 27, the single chip 27 sends a position signal of the camera module 2 through the UART module to notify the ISP image signal processor 26 that the camera module 2 has reached the shooting station; when the user restores the camera module 2 to the hidden station (the included angle between the lens bearing base 21 and the non-light-emitting side of the display screen 11 is smaller than 90 degrees), the acceleration sensor sends an interrupt signal INT2 to the single chip 27, the single chip 27 sends a position signal of the camera module 2 through the UART module to notify the ISP image signal processor 26 that the camera module 2 has reached the hidden station.

Fig. 14 shows a specific processing flow of the ISP image signal processor 26, wherein when the camera module 2 arrives at a shooting position, a user can send an open instruction for opening a camera application through the remote controller, the signal receiving machine receives a remote control signal sent by the remote controller, the main control chip 14 on the motherboard 13 can convert the remote control signal into an instruction in a USB format, and send the instruction to the ISP image signal processor 26 through the first interface 15 and the second interface 28, the television needs to call the camera, the ISP image signal processor 26 sets the Power Down of the image sensor 23 to a high level, the image sensor 23 collects original data of a shot image and transmits the original data to the ISP image signal processor 26, and the ISP image signal processor 26 performs image optimization on the original data of the image, including lens 22 defect compensation, noise processing, contrast/color enhancement, image quality adjustment, and color quality adjustment, Video scaling, etc., to generate YUV data (video stream) necessary for encoding. Then the data is encoded (MJPEG/H.264/H.265) and packed into a USB format to be sent to the main control chip 14 for decoding. Meanwhile, the ISP controls the indicator lamp 24 to be lightened through the GPIO, and can prompt a user that the camera is working.

When a user restores the camera module 2 to a hidden station (an included angle between the lens bearing base 21 and the non-light-emitting side of the display screen 11 is smaller than 90 degrees), if the current image sensor 23 is in a flow-out state (the camera module 2 is in an open state), the display can also automatically close the camera module 2, the acceleration sensor sends an interrupt signal INT2 to the single chip microcomputer 27, the single chip microcomputer 27 sends position information to the ISP image signal processor 26 through a UART module, the ISP image signal processor 26 sets Power Down of the image sensor 23 to be low level, the ISP image signal processor 26 does not output data stream, and the ISP image sensor 23 controls the indicator lamp 24 to be closed, at the moment, the camera module 2 is closed, and the user is informed very intuitively whether the camera works normally or not through the on and off of the lamp, so that the privacy of the user is protected; if the image sensor 23 is in the no-flow state (the camera module 2 is in the off state), only the current position information of the camera module 2 needs to be saved.
