[0045] Figure 4 It is a block diagram of the internal structure principle of the intelligent terminal provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] The technical problem that the present invention aims to solve is that the existing projection equipment may affect the user's vision when the light source is directly projected or the user passes in front of the light source. In particular, in home and educational environments, children and adults may be affected by strong light and their vision may be affected when they pass in front of the projection light source without knowing it. In addition, the prior art lacks an effective automatic adjustment mechanism to reduce this risk.

[0049] To this end, the present invention provides an eye protection control method for a projection light source, such as Figure 1 As shown, a method for controlling eye protection of a projection light source according to Embodiment 1 of the present invention comprises the following steps:

[0050] Step S100: pre-setting the brightness parameter, color temperature parameter, contrast parameter, and saturation parameter for starting the preset eye protection mode.

[0051] In the embodiment of the present invention, a projection display device is used as an example for explanation. Before implementation, it is necessary to pre-set the brightness parameter, color temperature parameter, contrast parameter, and saturation parameter for starting the preset eye protection mode. For example, the brightness parameter is set at 100-200 lumens, the color temperature parameter is set at 3000K-4000K warm tones, the contrast parameter is set at 50%, and the saturation parameter is set at 70%. This parameter setting can protect the user's eyes well.

[0052] Step S200: Using image recognition technology, real-time detection of whether a person enters the area in front of the projection light source;

[0053] In the embodiment of this step, a camera in front of the projection can be used to identify objects entering the area in front of the projection light source using image recognition technology, and to detect in real time whether a person enters the area in front of the projection light source.

[0054] Specifically, in the embodiment of this step, a camera in front of the projector is used to monitor and capture the image in the area in front of the light source, that is, the present invention sets a safety monitoring area in front of the image projected by the projector.

[0055] The present invention uses computer vision and deep learning algorithms to analyze the real-time video stream acquired by the camera to identify objects (such as people, animals, etc.) entering the area; and to classify and identify targets of different shapes, sizes and colors.

[0056] Furthermore, the present invention will continuously monitor the captured image data, timely determine whether there is an object entering the area in front of the projection light source, and make corresponding feedback.

[0057] For example, in an art exhibition, there is a projection work in the exhibition that needs to show an image of an excellent design. If the solution of the present invention is used, when a viewer tries to approach the projection area, the camera will capture this action in real time and identify it. If it is detected that a viewer enters the front of the projection, the image brightness can be automatically reduced in the subsequent steps of the present invention to avoid interfering with the viewer's visual experience or negatively affecting the image content.

[0058] This step ensures that the dynamics of entry and exit are monitored and fed back in a timely manner, better protecting the audience's surprise and safety, while also increasing the interactivity and intelligence of the work display.

[0059] It can be seen that, by detecting the behavior of the audience, the present invention can dynamically adjust the projection content or brightness according to the flow of people or the number of the audience, so as to make the audience experience more comfortable and reduce visual interference.

[0060] Step S300: When a person is detected to enter the area in front of the projection light source, the preset eye protection mode is automatically triggered and started;

[0061] In an embodiment of the present invention, when it is detected that a person enters the area in front of the projection light source, and the face recognition technology recognizes that a face enters the area in front of the projection light source, the control automatically triggers the start of the preset eye protection mode.

[0062] Specifically, in the embodiment of the present invention, regarding person detection and recognition, firstly, a camera installed near the projection device is used to detect whether an entity enters the area in front of the projection light source using image recognition technology. Once a person is detected, face recognition technology is further applied to identify whether the person entering the area is a person.

[0063] In this step embodiment, once it is confirmed that someone has entered this area, the eye protection mode is automatically triggered. The eye protection mode may include functions such as reducing the projection brightness and adjusting the color temperature, as described in step S400, to protect the audience's visual health and avoid eye discomfort or damage caused by direct strong light.

[0064] For example, take an educational exhibition as an example. There is a video of a scientific experiment displayed by projection in the exhibition. When the exhibition starts, the brightness of the projected content is high, which is suitable for clear display. However, if the present invention recognizes that someone is approaching the projection area, the present invention will immediately recognize the presence of someone through detection and face recognition. It will automatically start to switch to eye protection mode, reduce the projection brightness and contrast, and ensure that the audience is no longer exposed to strong light.

[0065] This eye protection mode not only ensures the safety and health of the audience, but also effectively enhances the audience's enjoyment of the exhibition content. This intelligent response mechanism makes the event environment more humane and safer.

[0066] The present invention automatically starts the eye protection mode by recognizing that a person enters the projection light source area, thereby effectively reducing the direct stimulation of strong light to the audience's eyes and reducing visual fatigue and eye discomfort caused by long-term observation of strong light projection.

[0067] Step S400: when the preset eye protection mode is activated, the brightness of the projection light source is reduced to a preset brightness according to a preset brightness parameter, and the user is reminded through a built-in voice broadcast function that the eye protection mode has been entered;

[0068] In this step embodiment, after detecting that a face enters in front of the projection light source and activating the eye protection mode, the next step is to adjust the projection brightness to the preset eye protection mode brightness. Specifically, the projector will automatically reduce the brightness of its projection light source according to the preset brightness parameters. This adjustment is based on pre-set standards that take into account the best viewing experience and the visual health of the audience in different environments.

[0069] In the embodiment of the present invention, after the brightness adjustment is completed, a built-in voice broadcast function will be used to prompt the user to inform the user that the eye protection mode has been entered. This voice feedback can remind the user that he is in a safer and more comfortable viewing environment.

[0070] For example, take a children's science exhibition as an example, when the exhibition displays colorful projected animations. When the exhibition begins, the projection brightness is set to a high level to ensure that the image is clearly visible. However, a parent walks in front of the projection light source with a child. At this time, the method of the present invention can detect the presence of people and automatically start the eye protection mode. When the eye protection mode is activated, the brightness of the projection will be adjusted to a preset safety level, such as reduced to about 30% brightness, so that the details of the picture can be displayed without being dazzling. At the same time, the built-in voice system will announce: "Eye protection mode has been activated, the projection brightness has been reduced, please pay attention to eye protection." Such prompts not only let the surrounding audience know that the system is making adjustments, but also remind them to enjoy the content in a comfortable lighting environment.

[0071] In general, the solution of the present invention improves the safety and comfort of exhibition viewing, especially for children and other visitors who are sensitive to light, and protects their visual health to the greatest extent.

[0072] When the present invention recognizes that someone has entered the projection light source area, the eye protection mode can effectively reduce the stimulation of strong light to the audience's eyes by reducing the brightness, reducing the risk of eye fatigue and other vision problems. In addition, the voice prompt not only allows the audience to understand the current status, but also enhances their understanding and trust in the use of the technical system, thereby improving the overall viewing experience.

[0073] Furthermore, the step S400 specifically includes:

[0074] S401, when the preset eye protection mode is activated, the brightness of the projection light source is reduced to a preset brightness according to a preset brightness parameter;

[0075] S402, and adjusting the color temperature of the projection light source to a preset color temperature according to a preset color temperature parameter;

[0076] S403, and adjusting the contrast of the projection light source to a preset contrast according to a preset contrast parameter;

[0077] S404, and adjusting the saturation of the projection light source to a preset saturation according to a preset saturation parameter;

[0078] S405, and reminds the user through the built-in voice broadcast function that the user has entered the eye protection mode.

[0079] For example, in an embodiment of the present invention, when the preset eye protection mode is activated, the following parameter adjustments are performed:

[0080] 1) Automatically set brightness parameters: Reduce the projection brightness, which is usually set at around 100-200 lumens. When watching movies in a dark environment, lower the brightness to 200 lumens to help reduce eye fatigue.

[0081] 2) Automatically adjust the color temperature parameters: lower the color temperature to 3000K-4000K (warm tone), while the standard color temperature is usually between 5000K-7000K. When using the projector for a family meeting at night, adjust the color temperature to 3500K to make the display content softer and reduce the damage of blue light to the eyes.

[0082] 3) Automatically set contrast and saturation parameters, such as appropriately reducing contrast (such as setting it to 50%) and saturation (such as setting it to 70%). When reading or displaying documents for a long time, using the settings of reduced contrast and saturation can make the text easier to read and reduce visual fatigue.

[0083] In the embodiment of the present invention, the eye protection mode is turned on when the user is studying or working online for a long time, and the parameters are automatically adjusted to protect the user's eyesight.

[0084] Step S500: When it is detected that the person has completely left the area in front of the projection light source, the projection light source is automatically restored to the brightness setting before the eye protection mode is activated.

[0085] In an embodiment of the present invention, if a person is detected entering the projection light source area in the previous step, the camera in front of the projector will continue to be used to identify the object entering the area in front of the projection light source; when it is detected that the person has completely left the area in front of the projection light source, the control will automatically restore the projection light source to the brightness setting before the eye protection mode was activated.

[0086] Regarding motion detection, the present invention continuously monitors the area in front of the projection light source to ensure whether there are still people remaining in this area. Once the person who previously entered the area has completely left, the system will recognize that there is no human body in the area. After confirming that no one is present, the present invention will automatically restore the brightness of the projection light source to the setting before the eye protection mode was activated. This means that the projection brightness will be readjusted to the brightness level for the best effect of the exhibition or content display. This process is completed automatically, and the audience does not need to intervene manually, maintaining the smoothness and consistency of the viewing experience and achieving a seamless transition.

[0087] After the present invention restores the original brightness setting, the display effect of the projected content will return to the optimal state, allowing the audience to clearly appreciate the details and colors of the projection and restore the best viewing experience. The automatic detection and recovery function makes the operation of the entire system more intelligent, improves the user experience, and the audience can continue to watch without interruption, and the experience is more natural. While ensuring the safety of the audience's eyesight, it can restore the optimal brightness of the displayed content in time to ensure that the audience's overall viewing experience is not damaged. In addition, the automated adjustment of the present invention eliminates the need for human intervention, reduces dependence on staff, and ensures the smooth progress of activities, especially in large-scale events or exhibitions, so that staff can focus on other more important tasks.

[0088] The present invention is further described in detail below through a specific application example:

[0089] like Figure 2 As shown in the figure, the interaction process between the projection device and the user is shown, including the logical process of user recognition, eye protection mode triggering and voice broadcast reminder. Figure 2 As shown, a method for controlling eye protection of a projection light source according to a specific application embodiment of the present invention comprises the following steps:

[0090] Step S31, when the projector is turned on, the camera of the projector performs a permanent detection. When it is detected that there is no human figure in the projection screen, the process proceeds to step S32. When a person is recognized in the projection screen, the process proceeds to step S33.

[0091] Step S32: Normal output.

[0092] Step S33: The MCU processor receives and processes relevant data, and simultaneously enters steps S34, S35, and S36.

[0093] Step S34: The LED driving part reduces the brightness by adjusting the PWM duty cycle.

[0094] For example, the LED driver part can be controlled through a two-wire interface protocol (IIC protocol, a serial communication protocol) to reduce the brightness by adjusting the PWM duty cycle;

[0095] Step S35: a prompt UI pops up on the screen.

[0096] For example, the screen may be controlled to pop up a prompt UI through the UART protocol (Universal Asynchronous Receiver / Transmitter, a universal asynchronous serial communication protocol).

[0097] Step S36: the sound cavity speaker plays a prompt tone.

[0098] For example, the sound cavity speaker can be controlled to play the prompt tone through the UART protocol (Universal Asynchronous Receiver / Transmitter, a universal asynchronous serial communication protocol).

[0099] In the embodiment of the present invention, specifically, the present invention has developed an intelligent control method, which monitors in real time through a camera and identifies whether the user passes in front of the projection light source, thereby automatically triggering the eye protection mode, reducing the brightness and performing voice broadcast reminders.

[0100] The present invention adopts intelligent recognition and automatic adjustment, specifically using a camera to identify the user, and automatically adjusting the brightness of the projection light source in combination with an intelligent algorithm. The present invention combines the eye protection mode with user behavior recognition, and improves the comfort and safety of viewing by reducing the brightness and voice reminders. This is an innovative application in traditional projection equipment. And through intelligent control, the user experience is improved, making the projection equipment more humane, while also protecting the user's vision health.

[0101] The present invention uses high-precision image recognition technology to achieve user recognition, which can ensure accurate recognition of users under different light and backgrounds. It also uses technology that automatically adjusts the brightness of the projection light source, which can quickly respond and accurately control brightness changes to achieve eye protection effects.

[0102] In addition, after the eye protection mode is activated in the embodiment of the present invention, while the brightness is reduced, an instant voice broadcast system is activated to remind the user, and the system has the capability of fast response and clear voice output.

[0103] It can be seen from the above that by implementing the present invention, the following effects can be achieved:

[0104] Vision protection: effectively reduce the light damage to users when passing in front of the projection light source, and protect the user's vision health.

[0105] Improved user experience: Voice notifications enhance the user's interactive experience, allowing users to learn about changes in light source status in a timely manner.

[0106] Intelligent control: It realizes intelligent control of projection equipment and improves the automation level and response speed of the equipment.

[0107] Of course, in a further embodiment of the present invention, in addition to the camera, other sensors such as infrared sensors and laser radar (LiDAR) can be combined to improve the accuracy and response speed of user recognition.

[0108] Of course, in further embodiments, the present invention can also achieve dynamic brightness adjustment in the eye protection mode, such as dynamically adjusting the brightness according to the ambient light and user behavior, rather than just reducing the brightness. As well as setting the color temperature adjustment and adjusting the color temperature of the light source, the proportion of blue light can also be reduced to further protect eyesight.

[0109] Of course, in further embodiments, the present invention can also provide multi-language voice broadcast options in the eye protection mode to meet the needs of different users. A voice recognition function can also be added to allow users to control the brightness and other settings of the projection device through voice commands.

[0110] Of course, in a further embodiment, the present invention can also set an intuitive graphical user interface in the eye protection mode, so that users can easily configure and adjust the parameters of the eye protection mode. It is also possible to develop a mobile application that allows users to remotely control the projection device and receive reminders of the eye protection mode.

[0111] Of course, in further embodiments, the present invention can also be set in the eye protection mode, in addition to reducing the brightness, to completely shut down the projector or set it to energy saving mode when the user leaves. An integrated ambient light sensor is also provided to automatically adjust the projection brightness according to the indoor light to reduce energy consumption.

[0112] Of course, in a further embodiment, the present invention can choose to blur the camera image when identifying the user in the eye protection mode to protect the user's privacy. It can also be set to temporarily lock the control of the projector in addition to reducing the brightness when the user passes by to prevent misoperation.

[0113] Of course, in further embodiments, the present invention can also add an integrated eye fatigue monitoring function in the eye protection mode, which can automatically adjust the projection settings according to the user's eye condition, and provide health tips after long-term use, suggesting that the user take a rest or do eye exercises.

[0114] Of course, in further embodiments, the present invention can also be set in the eye protection mode to adapt to different application scenarios according to the different users identified, such as educational scenarios, designing a specific eye protection mode for the classroom environment, taking into account the students' visual health and learning efficiency; and home theater: designing an eye protection mode for the home theater environment, taking into account the different needs and viewing habits of family members.
