Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
In the description of the present invention, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
With the popularization and application of televisions, personal computers and smart phones, and the rapid development of novel display technologies represented by virtual display, laser display and the like, visual health problems related to display are increasingly prominent. American investigation showed that 65% of the people developed different degrees of "digital asthenopia" symptoms, including shoulder and back soreness (36%), asthenopia (35%), headache (25%), blurred vision (25%), dry eye (24%). Visual fatigue may reduce work efficiency in the short term and may cause visual damage in the long term. China faces a more serious visual health crisis than western countries, with visual health becoming a major concern. The national health vision report issued by the Beijing university Chinese health development research center 2015, 6, indicates that the total number of people suffering from myopia is about 4.5 hundred million in the general population of China over 5 years old in 2012. Blue light is the most damaging for visible light, and its damage to the eye is mainly in the retina. Ultraviolet light and infrared light are typically absorbed by the cornea and lens and thus do not generally strike the retina. Blue light can penetrate the lens to the retina, causing photochemical damage thereto, accelerating oxidative damage of cells in the macular region. The blue light hazard refers to photochemical damage of the retina exposed to blue light radiation. Blue light of short wavelength contains high photon energy and can cause serious damage to the retina.
Moreover, the transmittance of eyes of people of different ages to blue light wavelength is different, the children's lenses are relatively clear, and blue light is easy to penetrate and directly reach retina. At ages 0-1, approximately 70-80% of the blue light may penetrate the lens to the retina, while at ages 60, approximately 40-50% of the blue light may strike the retina. The reason for this difference is that the color of the lens becomes more and more yellow with age.
For children, the blue light transmittance of the lens is high, and the retina is damaged by the blue light. For the aged, the blue light transmittance of the aged is low, the difference between blue colors and the intensity stimulation of a blue picture are not easily perceived, and the green light transmittance is also low, so that the display effect seen by eyes is poor and the image quality is poor for the aged.
Meanwhile, the distance between the user and the device also affects the display effect, and the closer the distance is, the stronger the blue light intensity is, and the farther the distance is, the weaker the blue light intensity is. Therefore, in order to achieve both eye protection and image quality, it is necessary to comprehensively consider the influence of both age and distance.
Based on the above-mentioned problem study, the embodiments of the present invention provide a display adjustment method, apparatus, electronic device, and storage medium, where after collecting the user age of the user and the distance information between the user and the device to be adjusted, the target display parameter of the device to be adjusted is obtained according to the user age and the distance information, and then the current display parameter of the device to be adjusted is adjusted according to the target display parameter. Thus, the influence of the age of the user and the distance between the user and the device to be adjusted on the display effect of the device to be adjusted is considered. The individuation of display is realized, the display image quality is improved, and the eye protection effect of the equipment to be regulated is enhanced.

S101: and collecting the user age of the user and the distance information between the user and the equipment to be adjusted.
Wherein the age of the user indicates the age of the user currently using the device to be adjusted; likewise, the distance information indicates the distance between the user currently using the device to be adjusted and the device to be adjusted.
In this embodiment, the device to be adjusted may be a display device or other electronic devices with display functions, for example: computers, televisions, electronic displays, etc., the present embodiment is not limited.
The user age of the user and the distance information between the user and the equipment to be regulated are collected again when the equipment to be regulated is started each time; in the using process, if the user is replaced, the current user can manually control to re-acquire; or the user age and distance information can be automatically acquired once at intervals of a fixed time; or may be acquired in real time. As long as the display effect of the equipment to be regulated is ensured to be matched with the user using the equipment to be regulated at present, the eye protection effect is better, the best image quality is provided, and other equivalent acquisition modes can be adopted by the person skilled in the art. It should be understood that the collection manner described in this embodiment is merely illustrative, and is not limited to the user age and distance information collection mode.
In this embodiment, there are multiple collection modes when collecting the age of the user. If the user manually inputs the age, the voice recognition or the face recognition, and the like, responding to the operation of inputting the age by the user when the user manually inputs the age, and obtaining the age of the user; when voice recognition is adopted, if a user speaks a statement such as … of my age, the user age is obtained through recognition; and when the face recognition mode is adopted, acquiring a user image, and extracting characteristics of the user image to obtain the age of the user. It can be appreciated that the above embodiments are only examples of the user age acquisition mode, and in practical applications, those skilled in the art may equally substitute according to requirements, and the embodiments are not limited in detail.

S102: and obtaining target display parameters of the equipment to be regulated according to the age and distance information of the user.
The target display parameters of the device to be adjusted are those that are affected by the age difference and the distance difference, such as blue light intensity, green light intensity, and the like, which are not limited in this embodiment.
In this embodiment, according to the correspondence between the age of the user and the display parameter of the device to be adjusted and the correspondence between the distance information and the display parameter of the device to be adjusted, the target display parameter corresponding to the age of the user and the distance information of the current user can be obtained. Wherein, the target display parameters are: aiming at the current user, the current display parameter of the equipment to be adjusted needs to reach the target value.
In this embodiment, the target display parameters of the device to be adjusted are determined according to the age and distance information of the user, and the difference between the user age and the display difference caused by the distance between the user age and the device to be adjusted is considered, so that the eye protection and the image quality are considered, and a better display effect can be achieved.

The device to be regulated needs to simultaneously protect eyes and image quality, and needs to know the damage of the device to be regulated to eyes and the factors influencing the image quality of the device to be regulated. From the viewpoint of eye protection, blue light is the most harmful, and damages the retina of human eyes, and ultraviolet light and infrared light in the visible light are generally absorbed by cornea and crystalline lens, so that the visible light is not generally irradiated to the retina; however, blue light with short wavelength contains high photon energy, which can cause serious damage to retina, and blue light can penetrate lens to reach retina, thereby causing photochemical damage and accelerating oxidative damage of macular cells. Moreover, existing studies have shown that the transmittance of the human eye lens to blue light is different at different ages, wherein the transmittance of the child's lens to blue light is highest and gradually decreases with age. The higher the blue light transmittance, the more easily the eyes are damaged, while the lower the blue light transmittance, the image quality and effect of human eyes are affected. And as the age increases, the transmittance of the aged's lens to green light also decreases, and the aged's viewing effect is also affected. Moreover, the blue and green light intensities in the device to be tuned are weaker the farther from the device to be tuned. If the eye protection effect and the display effect of the equipment to be adjusted are considered, the age difference of the user and the influence of the distance between the user and the equipment to be adjusted are also considered. Based on this, in this embodiment, by collecting the age and distance information of the user, the display effect of the device to be adjusted is adjusted according to the age and distance information of the user.
Optionally, in this embodiment, the step of collecting the user age of the user includes:
when the operation mode of the equipment to be regulated is a manual mode, responding to the operation of inputting the age by the user, and acquiring the age of the user;
and when the operation mode of the equipment to be regulated is an automatic mode, acquiring a user image, and extracting the characteristics of the user image to obtain the age of the user.
When the operation mode of the equipment to be regulated is a manual mode, the condition that the user manually inputs the age of the user through a remote controller or a control APP and other tools is referred to. In the manual mode, the age of the user can be obtained only by responding to the operation of inputting the age by the user and collecting the age.
The operation mode of the device to be adjusted is an automatic mode, which means that the device to be adjusted automatically collects the age of the user, and is an automatic collection mode which is set for the minors and the elderly who can not operate the remote controller and control the tool such as the APP, and the device to be adjusted defaults to the automatic mode, and is not switched to a manual mode until the remote controller or the tool such as the APP is controlled to switch the operation mode. In the automatic mode, the age of the user does not need to be manually input, the device to be adjusted can automatically collect the user image, and the feature extraction is carried out on the user image so as to obtain the age of the user.
Optionally, in this embodiment, the step of extracting features from the user image to obtain the age of the user includes:
analyzing and processing the user image, and extracting facial features or human body features of the user;
based on facial features or body features, the age of the user is determined.
The user image is different from the device to be adjusted according to the distance between the user and the device to be adjusted, if the user is close to the device to be adjusted, the user image can only acquire the face image of the user, and if the user is far away from the device to be adjusted, the user image can be acquired as a whole.
In this embodiment, the user image is automatically acquired by the camera. When the distance is short, extracting facial features of a user face image, constructing a neural network model for predicting the age of the user, and inputting the facial features into the neural network model for predicting the age of the user to obtain the age of the user; in this embodiment, the facial features may be facial textures, interpupillary distances, and the like. When the distance is far, the facial features or the human body features of the face image of the user can be extracted and input into a neural network model for predicting the age of the user to obtain the age of the user, wherein the facial features comprise the above features, and the details are not repeated here; the human body features may be human body gestures, etc., as long as the human body features and the facial features can be determined by the age of the user, and it should be understood that the facial features and the human body features in the foregoing embodiments are merely exemplified and are not to be construed as limiting the facial features and the human body features in the present embodiment.
In this embodiment, when the operation mode of the device to be adjusted is the automatic mode, the camera is used to collect the user image, and the user image is extracted by the features, so as to obtain the age of the user, so that the device is convenient to collect and does not need manual operation.
After the user age and the distance information are acquired, the influence of the user age and the distance information on the display effect of the equipment to be adjusted is required to be comprehensively considered, and the influence of the user age on the display parameter of the equipment to be adjusted and the influence of the distance information on the display parameter of the equipment to be adjusted are required to be respectively considered.
Optionally, in this embodiment, the step of obtaining the target display parameter of the device to be adjusted according to the age and the distance information of the user includes:
determining an age group corresponding to the user age according to the user age, and obtaining a distance difference value according to the distance information and a preset standard distance;
determining and obtaining age display parameters corresponding to age groups according to a preset display parameter relation library, and determining and obtaining distance display parameters corresponding to distance difference values according to the display parameter relation library; the display parameter relation library comprises age display parameters corresponding to each age group and distance display parameters corresponding to each distance difference value;
And determining and obtaining target display parameters according to the distance display parameters and the age display parameters.
The age groups are divided according to the change relation between the display parameters and the ages. The standard distance is a reference and is used for measuring the distance between a user and equipment to be adjusted; the standard distance can be selected from a plurality of choices, for example, a distance 1.5 times the diagonal of the display screen of the device to be adjusted is selected as the standard distance. It will be understood that, the distance 1.5 times the diagonal of the display screen of the device to be adjusted is taken as a standard distance by way of example only, and the specific value of the standard distance is not limited in this embodiment.
In this embodiment, the display parameter relation library stores the correspondence between the age of the user and the age display parameter, and the correspondence between the distance difference and the distance display parameter. When a display parameter relation library is established, firstly, dividing a plurality of age groups according to the change relation between the age display parameters and the ages, wherein each age group corresponds to one age display parameter, and the age display parameters represent the optimal value of the display parameter corresponding to the age group, so that the corresponding relation between the ages of the user and the age display parameters is obtained; correspondingly, a plurality of distance segments are divided according to the change relation between the distance display parameters and the distances, and each distance segment corresponds to one distance display parameter, so that the corresponding relation between the distance difference value and the distance display parameter is obtained.
If the distance between the user and the equipment to be adjusted is different from the standard distance, determining a target display parameter according to a distance display parameter and an age display parameter of a distance section corresponding to the distance difference. If the distance between the user and the equipment to be adjusted is equal to the standard distance, the current display parameter is the optimal value matched with the age and distance information of the current user, and adjustment is not needed.
Optionally, in this embodiment, the age display parameter is a display parameter value corresponding to the age group under the standard distance; the distance display parameter is an adjustment ratio determined according to the standard distance and the distance difference. For example: if the age display parameter corresponding to the age of the current user is X, and if the distance between the user and the equipment to be adjusted is a standard distance, the distance display parameter is 1, and the target display parameter is X; when the distance between the user and the equipment to be adjusted is greater than the standard distance, the distance display parameter is greater than 1, and the target display parameter is greater than X; when the distance between the user and the equipment to be adjusted is smaller than the standard distance, the distance display parameter is smaller than 1, and the target display parameter is smaller than X; the target display parameter is the product of the age display parameter and the distance display parameter.
Optionally, in this embodiment, the age display parameter is a display parameter value corresponding to the age group under the standard distance; the distance display parameter is an adjustment display parameter determined according to the standard distance, the distance difference value and the corresponding relation between the display parameter and the distance. For example, the currently adjusted display parameter is blue light intensity, which is related to distance: the farther the distance, the weaker the blue light intensity; if the age display parameter corresponding to the age of the current user is X, and if the distance between the user and the equipment to be adjusted is a standard distance, the distance display parameter is 0, and the target display parameter is X; when the distance between the user and the equipment to be adjusted is greater than the standard distance and the distance difference is Y1, obtaining an adjustment display parameter Z1 according to the corresponding relation between the blue light intensity and the distance, and obtaining a target display parameter X+Z; when the distance between the user and the equipment to be adjusted is smaller than the standard distance and the distance difference is Y2, the corresponding adjustment display parameter is Z2, and the target display parameter is X-Z2.
In this embodiment, when the target display parameter is determined according to the distance display parameter and the age display parameter, the age display parameter and the distance display parameter may have multiple characterization forms. When the age display parameter and the distance display parameter are used to calculate the target display parameter, various calculation modes, such as multiplication, addition, etc., may be adopted, and in practical application, the target display parameter is determined according to the representation modes of the age display parameter and the distance display parameter, which is not limited in this embodiment.
In this embodiment, in consideration of damage to eyes caused by blue light, in order to achieve an eye-protecting effect, the target display parameters in this embodiment include blue light intensity; i.e. the target blue light intensity is determined according to the user's age and the distance information of the user from the device to be adjusted. Therefore, the age groups in this embodiment are divided according to the difference of blue light transmittance of the crystalline lens of the human eye, for example, the blue light transmittance is divided into one age group with 70% -80% and one age group with 60% -70%. The age groups can be divided and adjusted by a person skilled in the art according to actual requirements.
In this embodiment, in order to balance the eye protection and display effects, the blue light transmittance of the lens of an adult is taken as a reference, so that the blue light intensity reaching the retina of a user in different age groups is ensured to be the same as that of the adult. In this embodiment, the reference age group serving as the reference is an adult age group, and the blue light transmittance of the lens in this reference age group is less damaged by the blue light of the retina, and can ensure that the display image perceived by the human eye is better. The reference age group can be determined by the blue light transmittance of the lens at different age stages, and the present embodiment is not particularly limited.
In this embodiment, if the display parameters include blue light intensity, the display parameter relation library includes a blue light intensity relation library, and when the blue light intensity relation library is established in order to comprehensively consider the age of the user and the distance between the user and the device to be adjusted, firstly, dividing the blue light transmittance according to different ages to obtain a plurality of age groups after dividing, where each age group corresponds to one age display parameter; according to the influence of the distance on the blue light intensity, dividing a plurality of distance segments, wherein each distance segment corresponds to a distance display parameter. And if the distance between the user and the equipment to be adjusted has a distance difference value, obtaining a target display parameter according to the distance display parameter and the age display parameter.
Optionally, in this embodiment, when the display parameter is blue light intensity, the age display parameter is age blue light intensity, and it is characterized that each age group is at a standard distance, so as to ensure that the blue light intensity falling on the retina of the human eye is the same as the selected reference age group, and the device to be adjusted needs to adjust the blue light intensity.
Optionally, in this embodiment, the target display parameter includes a target blue light intensity, and the step of adjusting the current display parameter of the device to be adjusted according to the target display parameter includes:
Determining and obtaining the value of the adjusting parameter of the blue light driving chip in the equipment to be adjusted according to the target blue light intensity; the adjustment parameters comprise at least one of current, voltage and duty cycle of the blue light driving chip;
and adjusting the current blue light intensity of the equipment to be adjusted according to the value of the adjusting parameter.
In this embodiment, when the target display parameter includes the target blue light intensity and the blue light of the device to be adjusted has an independent driving chip, the adjustment of the blue light intensity may be achieved by adjusting at least one of the current, the voltage, and the duty ratio of the driving chip. The blue light of the equipment to be regulated is required to be independently driven, so that the blue light intensity is regulated without influencing other display parameters.
Optionally, in this embodiment, the target display parameter includes a target blue light intensity, and the step of adjusting the current display parameter of the device to be adjusted according to the target display parameter includes:
determining the target electric field intensity according to the target blue light intensity;
and adjusting the deflection angle of the liquid crystal molecules corresponding to the blue light of the equipment to be adjusted according to the target electric field intensity so as to adjust the current blue light intensity of the equipment to be adjusted.
In this embodiment, when the target display parameter includes the target blue light intensity and the device to be adjusted is backlight driving, the blue light intensity may be adjusted by adjusting the deflection angle of the liquid crystal molecule corresponding to the blue light, that is, the deflection angle of the liquid crystal molecule may be controlled by adjusting the electric field intensity of the electric field where the liquid crystal molecule corresponding to the blue light is located, so as to adjust the blue light intensity. Likewise, it is ensured that the blue light intensity is adjusted without affecting other display parameters.
The target display parameters in this embodiment further include green light intensity, because the transmittance of the lens of the eyes of the elderly to green light gradually decreases with age, so that the perceived image quality of the eyes is poor for the population in the elderly, wherein the elderly is classified according to the transmittance of the lens of the eyes of different ages, and the embodiment is not limited. Therefore, in order to improve the perceived image quality of the eyes of the elderly, the intensity of blue light is adjusted as well as the intensity of green light.
Accordingly, when the green light intensity is adjusted in this embodiment, the green light transmittance of the lens of the adult is also used as a reference, so that the green light intensity reaching the retina of the aged user is ensured to be the same as that of the adult. In this embodiment, the reference age group used as the reference is an adult age group, and the green light transmittance of the lens in this reference age group is moderate, so that the display image perceived by human eyes can be ensured to be better. The reference age group can be determined by the green transmittance of the lens at different age stages, and the present embodiment is not particularly limited.
Therefore, in this embodiment, the adjustment of the green light intensity is also included for the aged user. I.e. the display parameters comprise green light intensity, the display parameter relation library comprises a green light intensity relation library, and the method for establishing the green light intensity relation library is the same as that for establishing the blue light intensity relation library. Firstly, dividing age groups according to the transmittance of green light of different ages, and obtaining a plurality of age groups after dividing, wherein each age group corresponds to one age display parameter; according to the influence of the distance on the green light intensity, a plurality of distance segments are divided, and each distance segment corresponds to one distance display parameter. And if the distance between the user and the equipment to be adjusted has a distance difference value, obtaining a target display parameter according to the distance display parameter and the age display parameter.
Similarly, in this embodiment, when the display parameter is green light intensity, the age display parameter is age green light intensity. Age green intensity characterizes each age group at a standard distance, ensuring that the green intensity falling on the retina of the human eye is the same as the selected reference age group, to which the device to be adjusted needs to be adjusted.
Optionally, in this embodiment, the target display parameter includes a target green light intensity, and the step of adjusting the current display parameter of the device to be adjusted according to the target display parameter includes:
according to the target green light intensity, determining and obtaining the value of the adjustment parameter of the green light driving chip in the equipment to be adjusted; the adjustment parameters comprise at least one of current, voltage and duty cycle of the blue light driving chip;
and adjusting the current green light intensity of the equipment to be adjusted according to the value of the adjustment parameter.
Similarly, in this embodiment, when the target display parameter includes the target green light intensity and the green light of the device to be adjusted has a corresponding individual driving chip, the adjustment of the green light intensity may be achieved by adjusting at least one of the current, the voltage, and the duty ratio of the driving chip. The green light of the device to be adjusted is required to be driven independently, so that the green light intensity is adjusted without affecting other display parameters.
Optionally, in this embodiment, the target display parameter includes a target green light intensity, and the step of adjusting the current display parameter of the device to be adjusted according to the target display parameter includes:
determining the target electric field intensity according to the target green light intensity;
and adjusting the deflection angle of the liquid crystal molecules corresponding to the green light of the equipment to be adjusted according to the target electric field intensity so as to adjust the current green light intensity of the equipment to be adjusted.
Similarly, in this embodiment, when the target display parameter includes the target green light intensity and the device to be adjusted is backlight driving, the green light intensity may be adjusted by adjusting the deflection angle of the liquid crystal molecule corresponding to the green light, that is, the deflection angle of the liquid crystal molecule may be controlled by adjusting the electric field intensity of the electric field where the liquid crystal molecule corresponding to the green light is located, so as to adjust the green light intensity. Likewise, it is ensured that the green light intensity is adjusted without affecting other display parameters.
According to the display adjusting method provided by the embodiment, from the viewpoints of eye protection and display image quality, according to the age of a user and the distance between the user and equipment to be adjusted, blue light intensity and green light intensity of the equipment to be adjusted are adjusted by taking the perception of the eyes of an adult on the blue light and green light as a reference. Comprehensively considering the influence of the age of the user and the distance between the user and the equipment to be regulated on the blue light intensity and the green light intensity.
In this embodiment, the target display parameters include blue light intensity, and for elderly persons with too low a green light transmittance of the lens, the target display parameters also include green light intensity. Therefore, the device to be adjusted in this embodiment may be an OLED display or a miniLED display. As long as the blue light intensity can be adjusted alone without affecting the display technology of other colored lights, or the display technology can be adjusted alone for both blue light intensity and green light intensity. For children, for example, the blue light of the device to be adjusted for children such as learning flat plates can be adjusted independently because the blue light transmittance of the lens of the children is high. If the equipment to be regulated is used by the old and young, such as televisions and computers, the display requirements of different age groups are considered, and the blue light intensity and the green light intensity can be regulated.
In the existing devices to be regulated, the maximum current, voltage or duty ratio is set for some devices to be regulated, or the condition that the deflection angle of the liquid crystal molecules is maximum, namely the light transmittance is maximum. When the age of the user is smaller than the reference age group or the current viewing distance between the user and the equipment to be adjusted is larger than the standard distance, the intensity of blue light or green light cannot be continuously enhanced in the existing equipment to be adjusted when the intensity of the blue light or the intensity of the green light needs to be enhanced, and the method is not suitable for the method. Therefore, in the display adjustment method provided in this embodiment, an adjustment space is reserved for the device to be adjusted, for example: when the blue light and the green light of the equipment to be regulated are provided with separate driving chips, the current, the voltage and the duty ratio of the driving chips are reserved on the basis of the value corresponding to the reference age group, and an up-adjustable space is reserved. When the device to be regulated is in backlight driving, a reserved liquid crystal molecule deflection angle corresponding to a reference age range is reserved, and is not the maximum deflection angle of the liquid crystal molecules, and an up-regulating space is reserved. The reserved adjustment space can be realized by means of software programming, hardware circuits and the like, and can be adjusted according to requirements by a person skilled in the art.
