detailed description

Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

Referring to FIGS. 1-4 , the control method according to the embodiment of the present invention is used to control the brightness of the display screen 130 of the electronic device 100 , and the feature is that the display screen 130 includes a pixel array 131 . Control methods include:

S01, detecting an overbright pixel 1311 whose brightness is greater than a predetermined brightness value;

S02, determining a predetermined coefficient according to the adjustment level;

S03. Multiply the difference between the luminance of the overbright pixel 1311 and the predetermined luminance value by a predetermined coefficient and add the predetermined luminance value to obtain the blended luminance of the overbright pixel 1311; and

S04. Adjust the overbright pixel 1311 to a blended brightness.

The control device 110 in the embodiment of the present invention includes a detection module, a coefficient determination module 112 , a calculation module 113 and an adjustment module 114 , which can be used to implement S01 , S02 , S03 and S04 respectively. That is to say, the detection module is used to detect the overbright pixel 1311 whose brightness is greater than the predetermined brightness value, the coefficient determination module 112 is used to determine the predetermined coefficient according to the adjustment level, and the calculation module 113 is used to compare the brightness of the overbright pixel 1311 with the predetermined brightness value The difference is multiplied by a predetermined coefficient and added to a predetermined brightness value to obtain the blended brightness of the overbright pixel 1311 , and the adjustment module 114 is used to adjust the overbright pixel 1311 to the blended brightness.

Please refer to FIG. 3 , in some embodiments, the electronic device 100 includes a mobile phone or a tablet computer. The electronic device 100 may include a light sensor 150 or an image acquisition device 170 for sensing ambient brightness. The image acquisition device 170 may be a camera.

When displaying on the display screen 130 of an electronic device 100 such as a mobile phone, it is often encountered that the brightness of a local area is too high and dazzles the eyes. If the overall brightness of the display screen 130 is adjusted, it is easy to cause the overall display to be dark, which makes the user experience bad and is not conducive to eye protection.

In the embodiment of the present invention, only the overbright pixels 1311 whose brightness exceeds a predetermined brightness value are adjusted, so that the brightness of the overbright area is reduced without affecting the brightness of the non-overbright area, thereby reducing the area of the adjusted brightness area as much as possible. Adjust the display on the display screen 130 under the premise of protecting the user's eyes. In this way, on the one hand, it protects the eyes, and on the other hand, it prevents the originally dark area from being too dark and affecting the user's viewing of the displayed content. In addition, different adjustment levels correspond to different predetermined coefficients, that is, corresponding to different adjustment strengths. In this way, different adjustment levels can be used for different situations to more accurately meet the user's eye protection and viewing needs.

Please refer to FIG. 4 , for example, the adjustment levels are divided into weak, medium, and strong, and the corresponding predetermined coefficients are 0.7, 0.4, and 0.1, respectively. Assuming that the predetermined brightness value is 50, and the brightness value of an overbright pixel 1311 is 100, the results of adjusting it at the weak, medium and strong adjustment levels are respectively:

(100-50)*0.7+50＝85;

(100-50)*0.4+50=70;

(100-50)*0.1+50＝55

The predetermined coefficient determines the adjustment range of the overbright pixel 1311, and the predetermined coefficient is generally a number greater than or equal to 0 and less than 1. If the predetermined coefficient is 0, it is equivalent to directly adjusting the overbright pixel 1311 to a predetermined brightness value, and if the predetermined coefficient is 1, it is equivalent to not performing any adjustment. The smaller the predetermined coefficient, the larger the adjustment range.

The smaller the predetermined coefficient, the smaller the adjusted brightness and the closer to the predetermined brightness value. Different adjustment levels correspond to different predetermined coefficients, so as to meet the individual needs of users. In addition to user input, the adjustment level can also be intelligently adjusted or switched according to user information such as the user's age and health status, so as to better adapt to the user's specific situation and adjust the brightness.

In some implementations, each overbright pixel 1311 corresponds to an independent adjustment coefficient, and the adjustment coefficient is determined according to the brightness of the overbright pixel 1311; the greater the brightness of the overbright pixel 1311, the smaller the adjustment coefficient.

That is to say, the adjustment coefficients corresponding to different overbright pixels 1311 may be different, and the magnitude of the adjustment coefficients is related to the brightness of the overbright pixels 1311 . Since the higher the brightness of an over-high pixel, the greater the damage to the eyes, so a smaller adjustment coefficient should be used. In this way, adjustments can be made for different situations of the overbright pixel 1311, thereby helping to achieve the purpose of eye protection.

There are many ways to determine the adjustment level. For example, please refer to FIGS. 5-6 . In some implementations, the control method includes: S05. Determine the adjustment level according to user input.

S05 may be implemented by the input module 115 of the control device 110 in some embodiments. That is, the input module 115 is used to determine the adjustment level according to user input.

In this way, users can set an appropriate adjustment level according to the current situation and their own needs. For example, the user's eyes are more sensitive to strong light, and the user can set the intensity adjustment level through input, and greatly reduce the brightness of the overbright pixel 1311 to protect eyesight.

For another example, referring to FIGS. 7-8 , in some implementations, the control device 110 includes:

S06. Determine the adjustment level according to the continuous opening time of the display screen 130 .

S06 may be implemented by the first level determination module 116 of the control device 110 in some embodiments. That is, the first level determination module 116 is used to determine the adjustment level according to the continuous opening time of the display screen 130 .

For example, when the display screen 130 of an electronic device 100 such as a mobile phone is continuously turned on for a first predetermined time, it automatically enters the low adjustment level; Three scheduled times to enter the emphasis level. The first predetermined time, the second predetermined time, and the third predetermined time may be 1 hour, 1.5 hours, and 2 hours respectively. When calculating the continuous on time of the display screen 130, the short screen off during the long time on can be ignored. In this way, the user's eye fatigue caused by watching the display screen 130 for a long time can be relieved, and the adjustment strength can be strengthened as the fatigue program increases.

For another example, referring to FIGS. 9-10 , in some embodiments, the control method includes:

S07. Determine the adjustment level according to the age of the user.

S07 may be implemented by the second level determination module 117 in some embodiments, that is, the second level determination module 117 is used to determine the adjustment level according to the age of the user.

The user's age can be input by the user, such as setting the entry of the user's personal information, and the personal information includes the item of age. For example, when the user enters (or is entered by the parents on behalf of the child) the age of personal information in the system is 9, the system recognizes the user as a child. Children's eyes are in the developing stage and need stronger protection. Therefore, a stronger adjustment level can be set to protect children's eyesight. In this way, the display of the electronic device 100 is more intelligent and humanized, and eye protection can be provided for different groups of people.

In addition to active input, it is also possible to use certain characteristics of the user to determine the age of the user. Referring to FIGS. 11-12 , in some implementations, the electronic device 100 includes an image acquisition device 170 for acquiring a user's face image; the control method includes:

S08, identifying the face image to determine the age of the user.

S08 may be implemented by the identification module 118 of the control device 110 in some implementations. That is, the identification module 118 is used to identify the face image to determine the age of the user.

The existing image processing technology can recognize the face in the image, as well as the facial features, wrinkles, skin fineness and other features of the user's face, and can roughly judge the user's age based on these features, and generate Trigger signal, i.e. age-specific brightness adjustment.

For example, referring to the above-mentioned embodiment of "the user input may be the age of the user", corresponding brightness adjustment is performed to protect the user's eyesight when it is determined that the user is a child.

In this way, the electronic device 100 can automatically judge the user's age so as to perform eye protection matching other ages, which has better application value when there may be multiple users of the electronic device 100 . For example, adults with children often worry that their children will affect their eyesight due to excessive use of their mobile phones for entertainment. If the electronic device 100 adopts the control method of this embodiment, it can automatically adjust the brightness of the display screen when the child uses the mobile phone, thereby protecting the child. vision.

In addition, a distance sensor can be set to sense the distance from the camera or electronic device 100 to the face, and according to the distance to the face and the size of the face in the face image, the size of the face can be converted to a face at a standard distance The size of the face is compared with the standard face size of people of all ages at a standard distance (the size difference between the face size of children and adults is large), and the age group corresponding to the user can be matched, so that it can be judged whether the user is a child or an adult. aldult.

Referring to Figures 13-14, in some embodiments, the control method includes:

S09, determining the adjustment rate according to the adjustment level;

In S04, the overbright pixel 1311 is adjusted to the blended brightness at the adjustment rate.

In some implementations, the control device 110 includes a rate determination module 119 for implementing S09, that is, the rate determination module 119 is used for determining the adjustment rate according to the adjustment level. The adjustment module 114 of the control device 110 is also used to adjust the overbright pixel 1311 to a harmonious brightness at an adjustment rate.

The adjustment rate refers to the adjusted brightness value of the overbright pixel 1311 per unit time. That is to say, different adjustment levels may correspond to different adjustment rates. For example, when the adjustment level is strong, it is often necessary to adjust a larger brightness value range for the excessively high pixels. Therefore, a faster adjustment rate can be set for the strong adjustment level to ensure that the brightness of the display screen 130 can be adjusted in a relatively short time. complete. In this way, adjusting to the harmonious brightness for eye protection as soon as possible helps to protect the user's eyesight.

In some embodiments, the predetermined brightness value is set according to user input. Since different users have different degrees of adaptation to highlighting, and users may have different adaptation procedures to brightness in different environments or places, it can be set that the predetermined brightness value can be set by the user himself. For example, setting an adjustment bar for a predetermined brightness value, the user can slide the adjustment bar with a finger to adjust the size of the predetermined brightness value. The predetermined brightness value can be increased when the ambient brightness is bright, and the predetermined brightness value can be adjusted when the ambient brightness is dark. Small.

Referring to Figures 15-17, in some embodiments, the control method includes:

S11, acquiring ambient brightness; and

S12. Determine a predetermined brightness value according to the ambient brightness.

S11 and S12 can be respectively implemented by the acquisition module 121 and the brightness determination module 122 of the control device 110 in some embodiments, that is, the acquisition module 121 is used to acquire the ambient brightness, and the brightness determination module 122 is used to determine a predetermined brightness value according to the ambient brightness.

Referring to FIG. 17 , for example, the sensed ambient brightness is used as the predetermined brightness value. For example, the ambient brightness is 54, so the predetermined brightness value is set at 54. If the adjustment coefficient is 0.4 at the medium adjustment level, then the overbright pixel 1311 with a brightness of 100 becomes (100-54)*0.4+50= after adjustment. 68.4.

The size of the pupil of the human eye changes with the change of the ambient brightness in the field of view. For example, when the brightness in the field of view is low, the pupils of the person dilate, and if the brightness of the display screen 130 is too high at this time, it will give strong stimulation to the human eyes, causing discomfort to the human eyes, that is, "dazzling". Therefore, the predetermined brightness value can be determined according to the ambient brightness, and the adjustment process is intelligent and convenient, giving users a good experience and helping to protect the eyes.

Please refer to FIG. 3 in conjunction with FIG. 3 . There are multiple ways to obtain ambient brightness. For example, in some implementations, the electronic device 100 includes a light sensor 150 , and the ambient brightness is obtained through the light sensor 150 . The light sensor 150 is a device widely used in electronic devices 100 such as mobile phones.

Please refer to FIG. 3 , in addition to the light sensor 150 , in some embodiments, the electronic device 100 includes an image acquisition device 170 for obtaining an image of the environment, and the brightness of the environment is obtained by calculating the brightness value of the image.

For example, the captured environmental image can be converted into HSL format to obtain the brightness value of each pixel, and then the brightness values of all pixels are added to obtain an average value, and the average value is used as the ambient brightness. The environmental image captured by the camera can cover a wider field of view, so a more objective environmental brightness can be obtained.

In addition, since a single image is taken, the brightness of the image may not be realistic and objective due to unexpected circumstances, such as fingers or other objects accidentally blocking the camera, or image distortion due to shaking. Therefore, multiple frames of images can be taken, and the average value of the average brightness values of each frame of images can be calculated as the average brightness. Further, screening can be performed in multiple frames of images, for example, eliminating images with too high or too low average brightness values (which may be caused by the above-mentioned accidents), and then using the remaining images to calculate the average brightness. In this way, more reasonable and objective results can be obtained.

The light sensor 150 and the image acquisition device 170 can also be used comprehensively, and even multiple image acquisition devices 170 can be used at the same time, for example, the front camera and the rear camera are used at the same time, so as to sense the ambient brightness from different angles and perform comprehensive calculations to obtain More objective ambient brightness.

Please refer to Fig. 18-19, the control method of the embodiment of the present invention can be triggered under certain conditions. For example, in some embodiments, the control method includes:

S11, acquiring ambient brightness; and

S13, judging whether the decrease range of the ambient brightness is greater than a predetermined range, and triggering S01 if the judgment is yes.

S11 and S13 can be respectively implemented by the acquiring module 121 and the judging module 123 of the control device 110 in some embodiments. Trigger the detection module when the judgment is yes.

At present, many electronic devices 100 such as mobile phones have the function of automatically adjusting the brightness of the display screen 130 according to the ambient brightness, for example, dimming the brightness of the display screen 130 when sensing that the ambient brightness is dimmed. Assuming that the brightness of the display screen 130 has been adjusted to a brighter state under relatively bright ambient brightness, if the ambient brightness drops significantly at this time, the control method may be triggered to dim the area with too high brightness to protect the user's eyesight.

Ways to acquire the ambient brightness include sensing by the light sensor 150, acquiring by the image acquisition device 170, etc. You can refer to the above-mentioned description of the corresponding ambient brightness acquisition method in some implementations in which the predetermined brightness value is obtained according to the ambient brightness. More details.

The control method can also be triggered according to user input. In some embodiments, S1 is triggered according to user input. In the control device 110 in some embodiments, the detection module is triggered according to user input.

For example, set a virtual button for intelligent brightness adjustment, trigger when the user clicks, or trigger S1 when entering the intelligent adjustment mode according to user input. In this way, the user's demand for brightness adjustment can be better met.

The control method can also be triggered according to the continuous turn-on time of the display screen 130 , for example, in some implementations, S1 is triggered when the continuous turn-on time of the display screen 130 reaches a predetermined time. In some implementations of the control device 110, the detection module is triggered when the continuous on time of the display screen 130 reaches a predetermined time.

For example, when the display screen 130 of the electronic device 100 such as a mobile phone is continuously turned on for a certain period of time, it will automatically enter into the smart eye protection mode and generate an alarm. When calculating the continuous on time of the display screen 130, the short screen off during the long time on can be ignored. In this way, the user's eye fatigue caused by watching the display screen 130 for a long time can be relieved.

In some implementations, the control method determines whether the proportion of the overbright pixels 1311 to all pixels is greater than a predetermined proportion after S01, and if so, proceeds to S02.

That is to say, if the number of overbright pixels 1311 is too large, or the overbright display area is too large, the brightness adjustment in the control method is performed; and if the number is small, no adjustment is required, because the user's eyes The impact is limited. In this way, intelligent judgment can be made, and the brightness adjustment of the control method can be triggered in a timely manner.

After S01, S02, S03 and S04 are triggered for the first time, since the display content of the display screen 130 changes in real time in many cases, that is to say, the brightness of each pixel may also change constantly, so some methods or steps are taken to Keep the display screen 130 in an eye-protecting state.

For example, in some implementations, the control method triggers S1 in real time to detect overbright pixels 1311 whose brightness is greater than a predetermined brightness value. In some implementations, the control device 110 triggers the detection module in real time to detect the overbright pixel 1311 whose brightness is greater than a predetermined brightness value.

In many cases, the display content of the display screen 130 changes in real time, that is to say, the brightness of each pixel may also change continuously, so it is necessary to detect the overbright pixel 1311 in real time and adjust the new overbright pixel 1311 . Only in this way can the display screen 130 be kept in an eye-protecting state.

For another example, referring to FIGS. 20-21 , in some implementations, the control method includes after S04:

S14. Trigger S01 when the display content of the display screen 130 changes.

S14 can be implemented by the trigger module 124 of the control device 110 in some embodiments, that is, the trigger module 124 is used to trigger the detection of the overbright pixel 1311 whose brightness is greater than a predetermined brightness value when the display content of the display screen 130 changes.

Taking a mobile phone or a tablet computer as an example, in many cases, the displayed content of the display screen 130 does not change in real time. content changes, and usually display content is static. In fact, except when playing video and games, in most of the other cases, the change of the displayed content is not real-time and infrequent. bright pixels 1311 and adjust overbright pixels 1311 .

In this way, the control method is triggered according to the change of the display content, which can not only meet the user's eye protection needs, but also simplify the workload and power consumption of the system, so that it can only adjust the brightness in a timely manner.

Whether the displayed content changes can be determined by detecting changes in brightness values of pixels or by detecting user operation signals. In addition, whether to generate a trigger signal to trigger the control method can also be determined according to whether the current application program (APP) or the application interface is switched.

In some implementations, after S4, the control method includes triggering S01 when it is detected that the user switches the application program or application interface.

The application interface can refer to different interfaces of the application program. For example, a social platform APP can include a chat interface, a friend list interface, an address book interface, a setting interface, etc.; an application interface can also refer to different interfaces with built-in functions of the system, such as the SMS function interface , phone call interface, system setting interface, etc. When the content displayed on the display screen 130 is switched from one APP to another APP, or when switching from one application interface to another application interface, the displayed content will change, and the brightness of each pixel will also change, so it is appropriate to trigger the implementation of the present invention. The control method of the method is to re-enter the bright pixel 1311 to detect and adjust. Detection of applications or application interfaces is simple and feasible.

In some embodiments, the display screen 130 includes a self-luminous display screen 130; the pixel array 131 includes an array of point light sources.

For example, in some embodiments, the self-luminous display screen 130 includes an OLED display screen 130 .

OLED (Organic Light-Emitting Diode) has the characteristic of self-illumination, so the OLED display 130 can implement an array of point light sources, and the brightness of each point light source can be adjusted by controlling the brightness of each point light source. In addition, the OLED display screen 130 has the advantages of thin thickness, good shock resistance, wide viewing angle, quick response, high luminous efficiency, and bendability.

By controlling the brightness of the point light source to adjust the brightness of the display screen 130, the control is more direct and the response is quick. By adjusting the brightness of the bright spot light source, the eye protection effect can be achieved.
