Description

Automatically turning on blue light filter eye protection system and method

The present invention relates to a security management method and system, and more particularly to a security monitoring method and system for securely managing a handheld device.

Using a mobile phone in a dark environment or turning off a light to watch an LED TV can easily cause eye injuries. According to research, blue light is one of the biggest killers of eye damage. Blue light does not mean blue light, but high-energy light with a wavelength of 400-500 nm, which is the most harmful to the eye. The blue light is closest to ultraviolet light and cannot be blocked before the crystal of the human eye. It can penetrate the lens and directly reach the retina. It causes the epithelial cells of the retinal pigment to die, and the decline of epithelial cells causes the light-sensitive cells to lack nutrients, causing visual impairment, and the damage is irreversible.

There are many sources of blue light, which are known from mobile phones, computers, etc. These artificial light sources contain a large number of high-energy short-wave blue light with irregular frequencies. Therefore, protective measures such as blue light filters, protective films, and anti-blue glasses have appeared on the market. However, the blue filter has only the switch adjustment and the filter percentage setting function, and the filter percentage is set to 10%, 30%, 50%, and 75%. These functions cannot be linked with other settings, and are not considered as ambient light sources or A mechanism that compensates for the light source.

In view of the above, it is necessary to propose an automatic opening blue light filter eye protection system, which can automatically turn on the blue light filter and adjust it synchronously by using its own brightness automatic adjusting unit to protect the eyes.

In addition, it is also necessary to propose an automatic eye-opening method for the blue light filter, which can automatically turn on the blue light filter and adjust it synchronously by using its own brightness automatic adjusting unit to protect the eyes.

An automatic opening blue light filter eye protection system running in an electronic device with a blue light filter, the system comprising: a detection module, configured to control the lens to be turned on when detecting that the display screen is illuminated, The color temperature of the current ambient light source is sensed; and the control module is configured to control the blue light filter to be turned on when determining that the color temperature of the current ambient light source is less than a preset color temperature value.

A method for automatically turning on a blue light filter eye protection, the method comprising: applying to an electronic device with a built-in blue light filter, the method comprising: detecting step, when detecting that the display screen is illuminated, controlling the lens Turning on to sense the color temperature of the current ambient light source; and controlling the step of controlling the blue light filter to be turned on when determining that the color temperature of the current ambient light source is less than the preset color temperature value.

Compared with the prior art, the automatic blue light filter eye protection system and method of the present invention can automatically turn on the blue light filter by using the sensing of the ambient light source, the setting of the brightness of the mobile phone, and the synchronous compensation of the ambient light source, and filtering the person. The blue light with large eye damage avoids the problem of excessive chromatic aberration after filtering blue light, and reduces the glare while playing a good eye protection effect.

Referring to FIG. 1, it is a system architecture diagram of a preferred embodiment of the present invention automatically turning on the blue light filter eye protection system.

In the present embodiment, the eye protection system 2 is installed and operated in an electronic device 1 incorporating a blue light filter 13. The electronic device 1 further includes, but is not limited to, the lens 10, sense The detector 11, the processor 12, the filter 14, the brightness automatic adjustment unit 16, and the display screen 15. The electronic device 1 may be a smart phone, a tablet computer, or any device that uses an LED display screen 15 such as a computer or a television.

The sensor 11 is built in the lens 10 for sensing the brightness of ambient light. In this embodiment, the sensor 11 is a light sensor.

The blue light filter 13 can forcibly change the LED illumination mode, and filter out part of the blue light, and the original white light is changed to white light with natural light yellow. In this embodiment, the blue light filter application program is used.

The brightness automatic adjustment unit 16 can automatically adjust the brightness of the display screen 15 according to the brightness of the ambient light sensed by the sensor 11. The brightness automatic adjustment unit 16 in the present invention is not a necessary unit.

The filter 14 is used to correct the color tone of the display screen 15 to avoid excessive color difference after filtering blue light, causing abnormal variation of visual sense and stereoscopic effect. The filter 14 may be a wafer, a filter application or the like.

The display screen 15 is used for displaying visual materials, which may be reading, browsing webpages, multimedia, and the like.

Referring to FIG. 2, it is a functional block diagram of a preferred embodiment of the system for automatically turning on the blue filter of the present invention.

The eye protection system 2 includes a detection module 21, a determination module 22, a control module 23, and an adjustment module 24. Each of the above modules is stored in the storage device of the electronic device 1 in the form of a code or an instruction, or is solidified in the operating system of the electronic device 1, and is executed by a controller of the electronic device 1, such as the processor 12. In order to realize the protection of the eye by automatically turning on the blue light filter 13 and synchronizing the adjustment by the brightness automatic adjusting unit 16.

The specific functions of the modules 21-24 will be described below in conjunction with the flowchart of FIG.

Referring to FIG. 3, it is a flow chart of a preferred embodiment of the method for automatically turning on the blue light filter eye protection of the present invention.

In step S10, when the detecting module 21 detects that the display screen 15 is illuminated, the control lens 10 is turned on.

In step S11, the determining module 22 determines whether the photographing instruction is triggered. The photographing instruction may be clicking a virtual photographing button, or pressing a physical button on the electronic device 1.

When the photographing instruction is not triggered, step S12 is performed; when the photographing instruction is triggered, the following step S18 is performed.

In step S12, the detecting module 21 detects whether the brightness automatic adjusting unit 16 is in an open state. If it is detected that the brightness automatic adjustment unit 16 is in the off state, step S20 is executed, and the control module 23 controls the display screen 15 to maintain the current brightness value.

For example, when reading, the filter 14 automatically adjusts the display screen 15 to a pale yellow color.

In the step S18, the detecting module 21 detects whether the blue filter 13 is in an on state. When it is detected that the blue light filter 13 is in the off state, the above-described step S17 is performed. When it is detected that the blue filter 13 is in the on state, step S19 is performed, and the control module 23 controls the blue filter 13 to be turned off.

In addition, it should be noted that step S12 is not a mandatory step. When there is no automatic brightness adjustment unit 16 in the electronic device 1, the present invention can still be implemented. When the step S11 determines that the camera instruction is not triggered, step S13 is directly executed. The detector 11 senses the color temperature of the ambient light source.
