[0047] See also Figure 2 , Figure 2 This is a flow chart of an eye protection method in an embodiment of the present invention. The method is applied to an eye protection device. The method specifically includes the following steps:

[0048] 301. Obtaining human eye feature information detected by a human eye detection module;

[0049] It can be understood that the human eye feature information detected by the human eye detection module will be transmitted to the control module included in the eye protection device. The human eye detection module can be a camera device with shooting and collecting capabilities. The human eye feature information includes but is not limited to the upper eyelid circumference, inner and outer corners, iris center, dark pupil area, bright pupil area, etc.

[0053] 304. Control the working state of the blue light film retractable module according to the control signal, wherein the working state includes retracting or unfolding the blue light film.

[0054] It should be noted that the working state of the blue light film retractable module can be controlled by outputting a control signal based on the line of sight, so that the blue light film can be retracted or unfolded according to different working states, thereby protecting the human eyes.

[0055] The present invention provides an eye protection method, which is applied to a blue light display device, and includes: obtaining human eye feature information detected by a human eye detection module; determining the line of sight relationship between the human eye and a screen included in the blue light display device according to the human eye feature information; using the line of sight relationship to output a control signal corresponding to the line of sight relationship; and controlling the working state of a blue light film retractable module according to the control signal, the working state including retracting or unfolding the blue light film. The method can automatically capture and determine the line of sight relationship between the viewer and the screen, control the working state of the blue light film retractable module according to different line of sight relationships, retract or unfold the blue light film, and automatically and spontaneously realize eye protection.

[0056] See also Figure 3 , Figure 3 It is a structural schematic diagram of an eye protection device in an embodiment of the present invention, the eye protection device is applied to a blue light display device 301, and the eye protection device includes: a human eye detection module 302, a control module (not shown) and a blue light film retracting and extending module 304; wherein, the human eye detection module 302, the control module and the blue light film retracting and extending module 304 are electrically connected in sequence; further, the human eye detection module is arranged on the blue light display device, and the human eye detection module is used to detect human eye feature information; the control module is used to determine the line of sight relationship between the human eye and the screen 303 included in the blue light display device according to the human eye feature information, and output a control signal corresponding to the line of sight relationship to the blue light film retracting and extending module using the line of sight relationship; the blue light film retracting and extending module is arranged on the target side of the screen, and the blue light film retracting and extending module is used to execute a corresponding working state according to the control signal to perform blue light filtering processing, and the working state includes retracting or unfolding the blue light film. Among them, the screen included in the blue light display device is a display medium used by the blue light display device to display image images. The screen can be a blue light screen or any display medium that can display based on optical signals, and this example is not limited here.

[0057] It should be noted that Figure 3 The human eye detection module 302, the control module and the blue light film retracting and releasing module 304 are shown. Figure 1 The human eye detection module 102, the control module and the blue light film retracting module 104 are similar, and are not described here to avoid repetition. For details, please refer to the aforementioned Figure 1 Content shown.

[0058] Furthermore, the human eye detection module 302 includes: an image processor (not shown) and an infrared camera (not shown) having an infrared light source which are electrically connected in sequence; the infrared camera is used to collect the target area using the infrared light emitted by the infrared light source, obtain the target collection data, and transmit the target collection data to the image processor; the image processor is used to extract the target human eye image using the target collection data, and obtain the human eye feature information, and the human eye feature information includes the bright pupil area and the dark pupil area. It can be understood that the target area is the preset viewing range in front of the screen, and the target collection data is the corneal reflection data when the infrared light is irradiated to the human eye.

[0059] Among them, the shooting principle of the infrared camera is that the infrared light source (Infrared, IR) emits infrared rays to illuminate the object, and the infrared rays are diffusely reflected and received by the camera to form a video image. Infrared rays are electromagnetic waves with a wavelength between microwaves and visible light, so they are invisible to the naked eye and difficult to detect. In this way, the infrared camera is used to collect human eye images, and the collected data is transmitted to the image processor to obtain the target human eye image. Further, the image processor can realize human eye tracking in combination with eye tracking technology. Eye tracking technology includes bright pupil tracking and dark pupil tracking. Due to the different positions of the light source, the target collection data is different, resulting in a bright pupil or dark pupil effect. When the infrared light source is consistent with the line of sight axis, the retina will reflect the light and a bright pupil effect will appear, so that the iris area in the corneal reflection data in the target collection data is a bright pupil area. When the infrared light source is offset from the line of sight axis, the reflection will be projected at a distance from the infrared camera, making the pupil appear dark, achieving a dark pupil effect, so that the iris area in the corneal reflection data in the target collection data is a dark pupil area effect. Therefore, by using eye tracking technology, the bright pupil area and dark pupil area of ​​the human eye can be obtained, and these two sensitive contrast areas can be used to obtain iris characteristics and corneal characteristics.

[0060] Furthermore, the blue light film retracting module 304 includes: a blue light film 314, a rotating shaft 324 and at least one rotating motor 334; the rotating shaft 324 is arranged on the first target side of the screen 303, one end of the blue light film 314 is connected to the rotating shaft 324 and the blue light film 314 is rolled up on the rotating shaft 324, the rotating motor 334 is coaxially arranged with the rotating shaft 324, and the rotating motor 334 is used to perform a rotational movement according to a control signal, and when performing the rotational movement, the blue light film 314 is retracted to the first target side of the screen or the blue light film 314 is unfolded to cover the screen 303.

[0061] It should be noted that there is at least one rotating motor, which is coaxially connected to the rotating shaft to drive the rotating shaft to rotate, so that the blue light film fixed on one end of the rotating shaft can also move synchronously when the rotating shaft rotates, so as to achieve the effect of folding or unfolding the blue light film. Optionally, the blue light film can be rolled up and stored on the rotating shaft for easy folding and unfolding. Figure 3 There are two rotating motors, which are respectively arranged at two ends of the rotating shaft and coaxially connected to the rotating shaft. The first target side is the left side of the rectangular screen. It can be understood that the first side can also be the upper side, the lower side or the right side.

[0062] Furthermore, the blue light film retracting and extending module also includes: at least one moving motor 344, at least two infrared probes 354 and at least one moving track 364; the moving track 364 is arranged on the second target side of the screen 303, and the first target side is vertically related to the second target side, the moving motor 344 is arranged on the moving track 364, and the moving motor 344 is connected to the other end of the blue light film 314, the moving motor is used to perform horizontal movement on the moving track 364 to move to the target position according to the control signal, and when performing the horizontal movement, the blue light film 314 is retracted to the first target side of the screen 303 or the blue light film 314 is unfolded to cover the screen 303; the infrared probe 354 is arranged on the first target side of the screen and on the opposite side of the first target side, and is used to detect the position of the moving motor 344 on the screen 303, and when the moving motor moves to the target position, a stop motion signal is output to the moving motor 344 and the rotating motor 334.

[0063] It should be noted that the moving track is used to move the motor to perform linear motion. The moving track is installed on the second target side of the screen, and the second target side is perpendicular to the first target side. Figure 3 For example, if the first target side where the rotation axis is located is the left side of the screen, then the first target side can be the upper side or the lower side of the screen. The moving motor is used to drive the blue light film to make a linear motion, and the linear motion is a horizontal motion. The other end of the blue light film is connected to the moving motor. When the moving motor moves, the blue light film will also move. It can be understood that one end of the blue light film and the other end of the blue light film are two opposite ends of a pair of blue light films. The number of moving motors is at least one.

[0064] The infrared probe is used to detect whether the mobile motor moves to the target position, which is the first target side or the opposite side of the first target side. Figure 3 For example, the first target side is the left side of the screen, and the side opposite to the first target side is the right side of the screen. Therefore, the number of infrared probes is at least two.

[0065] Among them, Figure 3For example, there are two mobile motors 344, which are respectively arranged on the upper side and the lower side, and then two mobile tracks are respectively arranged on the upper side and the lower side so that the two mobile motors move on the mobile tracks. There are four infrared probes respectively arranged at the two ends of the left side of the screen and the two ends of the right side of the screen. When the mobile motor moves to the position of the infrared probe, it can trigger the infrared probe to generate a sensing signal, thereby monitoring the position of the mobile motor.

[0066] The present invention provides an eye protection device, which is applied to a blue light display device, and the eye protection device comprises: a human eye detection module, a control module and a blue light film retracting and extending module; the human eye detection module, the control module and the blue light film retracting and extending module are electrically connected in sequence; the human eye detection module comprises an image processor and an infrared camera with an infrared light source which are electrically connected in sequence; the control module is used to determine the line of sight relationship between the human eye and the screen included in the blue light display device according to human eye feature information, and output a control signal corresponding to the line of sight relationship to the blue light film retracting and extending module by using the line of sight relationship; the blue light film retracting and extending module comprises a blue light film, a rotating shaft, at least one rotating motor, at least one moving motor, at least two infrared probes and at least one moving track. By setting up a human eye detection module, the visual relationship between the human eye and the screen included in the blue light display device can be automatically determined, and the moving motor and the rotating operation can be timely controlled according to the control signal output based on the visual relationship to fold or unfold the blue light film to perform blue light filtering processing, thereby automatically and spontaneously realizing eye protection without user participation. The blue light film can be folded in time according to the visual relationship, so there will be no problem of difficulty in disassembly, and it can be suitable for various types of screens.

[0067] Figure 4 This is another flow chart of an eye protection method in an embodiment of the present invention. The method is applied to an eye protection device. The method specifically includes the following steps:

[0068] 401. Obtaining human eye feature information detected by a human eye detection module;

[0069] The content shown in step 401 is similar to that shown in step 201 , and will not be described here to avoid repetition. For details, please refer to the content shown in the aforementioned step 201 .

[0070] It can be understood that different light and dark areas can be obtained through different tracking methods. This embodiment takes dark pupil tracking as an example. When the IR light source is turned on, when someone stands in front of the screen and watches the screen, the IR camera can capture the image of the viewer. The principle of image formation is that IR light enters the human eye through the pupil, and the pupil area of ​​the human eye has no light reflection to form a dark pupil area, while other areas outside the pupil have light reflection to form a bright pupil area. Therefore, the pupil forms a light and dark contrast with other parts. After the image is captured, the collected data enters the image processor through the optical sensor. Since the pupil has a light and dark contrast with other parts, the image processor can easily distinguish the pupil position and obtain the characteristic information of the human eye.

[0071] 402. Determine the iris area of ​​the human eye by using the dark pupil area and the bright pupil area;

[0072] Furthermore, the eye feature information includes a dark pupil area and a bright pupil area. Taking dark pupil tracking as an example, the dark pupil area is the pupil area and the bright pupil area is the cornea area. It can be determined that the dark pupil area is the iris area.

[0073] 403. Determine, according to the iris area, a line of sight relationship between a human eye and a screen included in the blue light display device;

[0074] In a feasible implementation, step 403 may include steps 4031 to 4033, wherein steps 4031 to 4033 are specifically as follows:

[0075] 4031. Project the iris region onto the screen to determine a projection area of ​​the iris region;

[0076] It is understandable that, since the human eye detection module is set on the screen, the detected human eye feature information is all located in front of the screen. Therefore, taking the screen as the projection surface, the projection area corresponding to the iris area can be obtained.

[0077] 4032. When the projection area meets a preset iris area threshold, determining that the sight line relationship between the human eye and the screen included in the blue light display device is a first sight line relationship, where the first sight line relationship is that the human eye is looking directly at the screen;

[0078] 4033. When the projection area does not meet a preset iris area threshold, it is determined that the line of sight relationship between the human eye and the screen included in the blue light display device is a second line of sight relationship, and the second line of sight relationship is that the human eye is not looking directly at the screen.

[0079] It should be noted that the comparison of the projection area with the preset iris area threshold can determine the line of sight relationship between the human eye and the screen. If the human eye is watching the screen, the iris of the human eye should be in a state of facing the screen, so the projection area at this time is close to the complete iris area, and if the human eye is not watching the screen, the iris of the human eye should be in a state of not facing the screen, so the projection area at this time will be much smaller than the complete iris area. Then, the projection area can be used to determine whether the human eye is facing the screen. Among them, the preset iris area threshold is an iris area interval, the maximum value of the interval can be the complete iris area, and the minimum value is 1 / 2 of the complete iris area. Among them, if the projection area meets the preset iris area threshold, it means that the projection area is in the iris area interval, and it can be determined that the line of sight relationship between the human eye and the screen included in the blue light display device is the first line of sight relationship in which the human eye is facing the screen. Similarly, if the projection area is not in the iris area interval, the projection area does not meet the preset iris area threshold, and the line of sight relationship is the second line of sight relationship in which the human eye is not facing the screen.

[0080] 404. Outputting a control signal corresponding to the line of sight relationship by using the line of sight relationship;

[0081] It can be understood that different sight lines correspond to different control signals to control the blue light film retractable module, and then the blue light film retractable module is controlled by outputting a control signal corresponding to the sight line relationship.

[0082] 405. Control the working state of the blue light film retractable module according to the control signal, wherein the working state includes retracting or unfolding the blue light film.

[0083] In a feasible implementation, the control module can convert the optical signal into an electrical signal through a photoelectric sensor to control the motor. The control signal includes a first control signal and a second control signal, and 405 can also include steps 4051-4052:

[0084] 4051. When the sight line relationship is the first sight line relationship, controlling the working states of the rotating motor and the moving motor according to the first control signal, so that the blue light film is unfolded to cover the screen;

[0085] It can be understood that the first line of sight relationship indicates that the human eye is facing the screen. At this time, the first control signal is used to protect the human eye. Therefore, the first control signal can make the blue light film cover the screen. Therefore, the first control signal can control the movement of the moving motor and the rotating motor to make the blue light film cover the screen, wherein the first control signal includes a first pulse signal of the movement of the motor, and the first pulse signal is used to control the movement of the rotating motor and the moving motor respectively. Figure 3 and Figure 5(a) to Figure 5(b) , Figure 3It can represent the state of the screen when no one is watching the screen. Figure 5(a) shows that when there is a first line of sight relationship, the first control signal controls the moving motor to move from the left side of the screen to the right side of the screen, and controls the rotating motor to rotate and unfold the blue light film, so that the blue light film covers the screen as shown in Figure 5(b) to filter the blue light.

[0086] It is understandable that when the blue light film completely covers the screen, if it is the first line of sight, there is no need to control the motor movement, and the status quo can be maintained. Therefore, the position of the mobile motor detected by the infrared probe can be obtained to determine whether to control the motor movement. If the infrared probe on the left side is triggered, it is determined that the motor needs to be started, and if the infrared probe on the right side is triggered, it is determined that the motor does not need to be started. This can be done by detecting the sensing signal of the infrared probe.

[0087] 4052. When the line of sight relationship is the second line of sight relationship, the working states of the rotating motor and the moving motor are controlled according to the second control signal so that the blue light film is retracted to the first target side of the screen.

[0088] It can be understood that the second line of sight relationship indicates that the human eye is not looking directly at the screen, and eye protection is not required at this time. Therefore, the second control signal is used to retract the blue light film to display the real screen color. Therefore, the second control signal can retract the blue light film to the first target side. Therefore, the first control signal can control the movement of the moving motor and the rotating motor to make the blue light film covering the screen retract to the first target side of the screen. Among them, the second control signal includes a second pulse signal for the movement of the motor, and the second pulse signal is used to control the movement of the rotating motor and the moving motor respectively. Please refer to Figures 5(b), 5(c) and Figure 3 FIG5(b) shows the screen state when the blue light film is covered on the screen, and FIG5(c) shows the screen state when there is a second sight line relationship, the second control signal controls the moving motor to move from the right side of the screen to the left side of the screen, and controls the rotating motor to rotate and retract the blue light film, so that the blue light film is as shown in FIG5(c). Figure 3 It is shown retracted to the first target side of the screen to display the actual imaging color of the screen.

[0089] It should be noted that if the first pulse signal is forward, the second pulse signal is reverse, or if the first pulse signal is reverse, the second pulse signal is forward. That is, the pulse signal controls the motor movement in the opposite way. Further, the pulse signal includes a stop signal, or the pulse signal is a continuous pulse signal, and when the trigger signal of the infrared probe, i.e., the stop motion signal, is received, the pulse output is stopped, and the motor is controlled to stop, which is not limited to this example.

[0090] It is understandable that when the blue light film is retracted to the first target side of the screen, if it is the second line of sight at this time, there is no need to control the motor movement, and the status quo can be maintained. The position of the mobile motor detected by the infrared probe can be obtained to determine whether to control the motor movement. If the infrared probe on the left side is triggered, there is no need to start the motor. If the infrared probe on the right side is triggered, it is determined that the motor needs to be started. Whether to output a pulse signal can be determined by detecting the sensing signal of the infrared probe.
