[0023] The technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-3 , the present invention provides the following technical solutions:

[0025] The multi-screen image viewing management control circuit includes several image input modules 1, an image processing module 2, an image display module 3, and a communication module 4. The several image input modules 1 are used to receive images from multiple sources and convert them into a unified format for subsequent processing. The image processing module 2 is used to enhance the image and enhance the details of the image. The image display module 3 is used to display the image. The communication module 4 is used to communicate with other external devices, can transmit the image to other devices, and can also use other devices to control the image display module 3. The image display module 3 includes a light intensity detection unit 30, a main control unit 31, and a touch screen unit 32. The main control unit 31 adjusts the touch screen unit 32 according to the ambient light intensity detected by the light intensity detection unit 30, and makes the touch screen effect and display effect better by changing parameters.

[0026] In this embodiment, the image input module 1 uses a variety of signal receiving interfaces. The signals can be in different formats such as RGB, YUV, and HDMI, and are decoded by a decoder and finally converted into a unified format.

[0027] Specifically, in the image processing module 2, gamma correction is used for multiple channels of the image to enhance the image. Gamma correction performs a non-linear transformation on the gray values of the image, so that the brightness response of the image conforms to the visual characteristics of the human eye, making the image have better contrast and detail performance in different brightness regions. In low-brightness regions, the human eye is more sensitive to brightness changes, so gamma correction will enhance the contrast in these regions; in high-brightness regions, the human eye is relatively less sensitive to brightness changes, so gamma correction will reduce the contrast in these regions to avoid overexposure. In this way, gamma correction can improve the overall perception and readability of the image.

[0028] Further, the light intensity detection unit 30 includes a power supply VCC, a photosensitive resistor R, a potentiometer RL, a first capacitor C1, a first resistor R1, a second capacitor C2, a first operational amplifier U1, a second resistor R2, a third resistor R3, and a second operational amplifier U2;

[0029] The first terminal of the photosensitive resistor R is connected to the power supply VCC, the second terminal of the photosensitive resistor R is connected to the inverting input terminal of the first operational amplifier U1, the first terminal of the first capacitor C1 is connected to the second terminal of the photosensitive resistor R, the second terminal of the first capacitor C1 is connected to the output terminal of the first operational amplifier U1, the first terminal of the potentiometer RL is connected to the inverting input terminal of the first operational amplifier U1, the second terminal of the potentiometer RL is connected to the output terminal of the first operational amplifier U1, the movable terminal of the potentiometer RL is connected to the output terminal of the first operational amplifier U1, the first terminal of the first resistor R1 is connected to the non-inverting input terminal of the first operational amplifier U1, the second terminal of the first resistor R1 is grounded, the first terminal of the second capacitor C2 is connected to the non-inverting input terminal of the first operational amplifier U1, the second terminal of the second capacitor C2 is grounded, the first terminal of the second resistor R2 is connected to the output terminal of the first operational amplifier U1, the second terminal of the second resistor R2 is connected to the inverting input terminal of the second operational amplifier U2, the non-inverting input terminal of the second operational amplifier U2 is grounded, the first terminal of the third resistor R3 is connected to the inverting input terminal of the second operational amplifier U2, the second terminal of the third resistor R3 is connected to the output terminal of the second operational amplifier U2, and the output terminal of the second operational amplifier U2 is also connected to the main control unit 31. The photosensitive resistor R is used to reflect the intensity of the ambient light by the change of the light intensity. The signal generated by the photosensitive resistor R is amplified and then transmitted to the main control unit 31. The main control unit 31 converts the analog signal into a digital signal through A / D conversion and obtains the ambient light intensity.

[0030] It should be noted that the touch screen unit 32 uses an infrared touch screen. The infrared touch screen uses an infrared matrix densely arranged in two directions to detect and locate the user's touch position. Its working principle is to install a circuit board outer frame in front of the screen, and infrared emitting tubes and receiving tubes are arranged inside the frame to form a horizontal and vertical cross infrared matrix. When the user touches the screen, the finger will block the infrared rays passing through this position, so as to judge the position of the touch point. The main control unit 31 adjusts the infrared touch screen parameters according to the ambient light intensity measured by the light intensity detection unit 30. The parameters include the intensity of the infrared reflection tube, the sensitivity of the infrared receiving tube, and the screen brightness, etc.

[0031] It should be noted that the communication module 4 is connected to the user device through infrared or Bluetooth, can transmit images to other devices, and can also be remotely controlled by other devices, making the operation more convenient.

[0032] When the multi-screen image review management and control circuit of the present utility model is in use, multiple image input modules 1 receive images from different sources and in different formats, and convert the images into a unified format. Then, the image processing module 2 uses gamma correction to enhance image details. The image display module 3 can be directly controlled by the user. By directly interacting with the touch screen unit 32, it manages and displays multi-screen images. The light intensity detection unit 30 detects the intensity of ambient light through the photosensitive resistor R, amplifies the detection signal and then transmits it to the main control unit 31. The main control unit 31 adjusts the parameters of the touch screen unit 32 according to the received signal, including the intensity of the infrared reflection tube, the sensitivity of the infrared receiving tube, and the screen brightness and other parameters, reduces the influence of ambient light on the touch screen, improves the display effect, improves the touch screen accuracy, and is convenient for management. In addition, the communication module 4 is connected to the user device through infrared or Bluetooth, can transmit the image to other devices, and can also be remotely controlled by other devices, with stronger practicability.
