The wearable device may be a smart watch, a smart bracelet, a watch phone, a smart foot ring, a smart earring, a smart necklace, a smart headset, or the like, and the embodiment of the present invention is not limited.
The executing main body of the light sensing detection method provided by the embodiment of the present invention may be the terminal device, or may also be a functional module and/or a functional entity capable of implementing the light sensing detection method in the terminal device, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited. The light sensation detection method provided by the embodiment of the invention is exemplarily described below by taking a terminal device as an example.
As shown in fig. 1, an embodiment of the present invention provides a light sensing method, which can be applied to the above terminal device, and the method can include the following steps:
101. and acquiring an initial light sensation value through the light sensation sensor.
In the embodiment of the invention, the terminal equipment can be provided with the light sensor below the screen, the light sensor can generate strain on the light intensity, the light sensor generates a photoelectric effect after being irradiated by visible light, and converts a light signal into an electric signal to be output, and the light sensor can measure the light intensity and can also measure various physical quantities such as size, displacement, speed, temperature and the like by utilizing the transmission, the shielding, the reflection, the interference and the like of light, so the light sensor is an important sensitive device with wide application and is often used in the fields of optical measurement and detection and the like. The light sensor can sense the ambient light condition, automatically adjust the backlight brightness of the display and reduce the power consumption of the product. When the ambient brightness is high, the light sensor can automatically adjust the brightness of the display to high brightness; when the ambient brightness is low, the light sensor can automatically adjust the brightness of the display to be low.
It should be noted that the initial light sensitivity value can be used to characterize the light intensity collected by the light sensor.
102. And determining a screen display parameter value corresponding to the screen position according to the screen position corresponding to the light sensor.
In the embodiment of the present invention, since the light sensor is disposed below the screen of the terminal device, the terminal device may determine a setting position of the light sensor below the screen, and determine a screen position corresponding to the light sensor according to the setting position of the light sensor below the screen, and then the terminal device may determine a screen display parameter value corresponding to the screen position according to the screen position corresponding to the light sensor.
It should be noted that the terminal device may only determine the screen display parameter value corresponding to the screen position corresponding to the light sensor, and since the screen display parameter values may be different in the content displayed in the screen, if the terminal device calculates the ambient light sensitivity value according to the screen display parameter value of the whole screen, the detection of the ambient light intensity by the terminal device may be inaccurate.
Wherein the screen display parameter values may include: pixel values, and backlight levels, etc.
Optionally, the pixel value includes: RGB values, or YUV values.
Alternatively, the RGB value is a color standard, and various colors are obtained by changing three primary color channels of red (R), green (G) and blue (B) and superimposing them on each other. The colors that can be seen by the naked eyes are formed by mixing the lights of three primary colors of red, green and blue according to different proportions, the RGB values refer to the brightness of the lights of the three primary colors, each light has 256 brightness values, and the brightness values are represented by numbers as 0, 1 and 2.
Optionally, YUV is a color coding method, and is mainly used for optimizing transmission of color signals. Compared with the transmission of RGB signals, the great advantage is that it only needs to occupy little bandwidth (RGB requires the transmission of three independent color signals at the same time). Here, "Y" is a baseband signal and represents brightness (Luminance), i.e., a gray scale value. The "U" and "V" represent chromaticity (chroma) which is used to describe the color and saturation of the image for specifying the color of the pixel. U and V are quadrature modulated signals. The YUV color model is derived from an RGB model, and is characterized in that the brightness and the chroma are separated, so that the YUV color model is more suitable for the field of image processing.
Optionally, the backlight level may refer to an intensity of Light emitted by a screen of the terminal device itself, and since an Active-matrix Organic Light-Emitting Diode (AMOLED) screen or an Organic Light-Emitting display (OLED) screen is generally adopted in the current terminal device, the AMOLED screen and the OLED screen may both emit Light, and the terminal device may control a luminance level of the screen Light emission, so that the terminal device may store a plurality of luminance levels of the screen Light emission in advance.
103. And acquiring a screen light sensation value corresponding to the screen display parameter value.
In the embodiment of the present invention, after determining the screen display parameter value corresponding to the screen position, the terminal device may determine the screen light sensation value corresponding to the screen display parameter value according to the pre-stored correspondence between the screen display parameter and the screen light sensation.
Wherein the screen light sensitivity value can be used for representing the light intensity of self-luminescence of the screen of the terminal equipment.
104. And determining the current ambient light sensitivity value according to the initial light sensitivity value and the screen light sensitivity value.
In the embodiment of the present invention, since the initial light sensation value is used to represent the light intensity collected by the light sensation sensor, and the light collected by the light sensation sensor may include ambient light and self-luminescence of the screen, a difference value between the initial light sensation value and the screen light sensation value is a current ambient light sensation value, and the ambient light sensation value may be used to represent the light intensity of the ambient light.
The embodiment of the invention provides a light sensation detection method.A terminal device is provided with a light sensation sensor below a screen, and the terminal device can obtain an initial light sensation value through the light sensation sensor; determining a screen display parameter value corresponding to the screen position according to the screen position corresponding to the light sensor, so as to obtain a screen light sensing value corresponding to the screen display parameter value; then, a current ambient light sensitivity value is determined according to the initial light sensitivity value and the screen light sensitivity value, and the ambient light sensitivity value is used for representing the light intensity of the ambient light. According to the scheme, the light sensor arranged below the screen can collect the ambient light and the screen light, so that the initial light sensing value obtained by the terminal equipment according to the light sensor is the sum of the ambient light sensing value and the screen light sensing value; and then the terminal equipment determines a screen light sensation value according to the screen position corresponding to the light sensation sensor, and the light sensation value obtained by the terminal equipment according to the initial light sensation value and the screen light sensation value is an accurate ambient light sensation value.
As an optional implementation manner, the terminal device may further include a plurality of light sensing sensors below the screen, where the setting position corresponding to each light sensing sensor is different, that is, the screen position corresponding to each light sensing sensor is also different, and at this time, the current ambient light sensing value is determined according to the initial light sensing value and the screen light sensing value, which may specifically include: the terminal equipment can determine a plurality of ambient light sensitivity values according to the plurality of initial light sensitivity values and the plurality of screen light sensitivity values; and determining the current ambient light sensitivity value according to the plurality of ambient light sensitivity values.
The plurality of initial light sensation values are acquired by the terminal equipment through the plurality of light sensation sensors, and the plurality of light sensation sensors correspond to the plurality of initial light sensation values one to one; the plurality of screen light sensation values are determined according to the plurality of screen display parameter values, and the plurality of screen display parameter values are determined according to the screen positions corresponding to the plurality of light sensation sensors, so that the plurality of light sensation sensors, the plurality of screen display parameter values and the plurality of screen light sensation values are respectively in one-to-one correspondence, namely, one light sensation sensor can determine one screen display parameter value, and one screen light sensation value can be determined according to the screen display parameter value.
It should be noted that the plurality of ambient light sensitivity values respectively correspond to the plurality of light sensor, and the terminal device may determine an ambient light sensitivity value through each light sensor, and then process the plurality of ambient light sensitivity values to obtain a current ambient light sensitivity value; the processing may specifically include: averaging, median processing, etc., and the embodiments of the present invention are not limited.
Through this optional implementation, terminal equipment can set up a plurality of light sense sensors and carry out the ambient light sense and detect to worth obtaining current ambient light sense value according to a plurality of ambient light senses, detect through setting up a plurality of light sense sensors, can avoid because of single light sense sensor is sheltered from or corresponds the screen display problem etc. and cause the inaccurate condition of detection, improved terminal equipment to the accuracy that ambient light intensity detected.
As shown in fig. 2, an embodiment of the present invention provides a light sensing method, which may further include the following steps:
201. and under the condition that the terminal equipment is in a dark test environment, controlling the test area on the screen of the terminal equipment to respectively display according to at least one group of screen test display parameter values.
In the embodiment of the invention, the terminal equipment needs to perform light sensation calibration on the light sensation sensor in advance, and the purpose of the light sensation calibration is to eliminate the influence of the screen light on the lighting of the light sensation sensor when the light sensation is actually detected, so that the terminal equipment can detect the influence of the screen light on the lighting of the light sensation sensor in advance, the influence of the screen light on the lighting of the light sensation sensor can be eliminated when the light sensation is actually detected, and the accurate ambient light sensation can be obtained.
Optionally, when the terminal device detects the influence of the screen light on the lighting of the light sensor, the terminal device needs to eliminate the influence of the ambient light on the lighting of the light sensor, and therefore the terminal device needs to be in a completely dark environment, and the light collected by the light sensor is the light emitted by the screen.
It should be noted that, in the embodiment of the present invention, when the terminal device is in a dark test environment, the test area on the screen of the terminal device may start to perform light emitting display, and in the light emitting display process, the screen test display parameter value may be adjusted at any time, that is, the test area on the screen of the terminal device is displayed according to the screen test display parameter value.
The content displayed in the test area on the screen of the terminal device may be a picture, a text, a video, etc., as long as the screen display parameter of the test area is a screen test display parameter value, which is not limited in the embodiment of the present invention.
Optionally, the test area is determined according to the arrangement position of the light-sensitive sensor below the screen.
It should be noted that the position of the test area on the screen of the terminal device is related to the position of the light sensor, so that the test area may be a screen area corresponding to the setting position of the light sensor below the screen, or may be another area determined according to the setting position of the light sensor below the screen, which is not limited in the embodiment of the present invention.
For example, the test area may be a screen area corresponding to the position where the light sensor is disposed below the screen, a part of the screen area corresponding to the position where the light sensor is disposed below the screen, or an area including the screen area corresponding to the position where the light sensor is disposed below the screen.
Through this optional implementation, because the light sense sensor gathers ambient light through its screen that the set position below the screen corresponds, therefore terminal equipment when detecting screen light also can detect the screen region that the set position of light sense sensor below the screen corresponds, can improve terminal equipment like this to the accuracy of ambient light intensity detection.
Optionally, the step of respectively displaying the test areas on the screen of the terminal device according to at least one group of screen test display parameter values by the terminal device includes: acquiring a value range corresponding to each screen test display parameter; dividing the value range of each screen test display parameter into a plurality of value intervals, and determining the screen test display parameter value in each value interval to obtain a plurality of groups of screen test display parameter values; and controlling the test area on the screen to respectively display according to the test display parameter value of each group of screens.
In this optional implementation manner, the test areas may be respectively displayed according to at least one set of screen test display parameter values, and then the terminal device may determine the value of the screen test display parameter according to the value range of the screen test display parameter.
Specifically, the terminal device can obtain a value range corresponding to each screen test display parameter, then divide the value range of each screen test display parameter into a plurality of value intervals, and determine a value in each value interval as a screen test display parameter value in the value interval, so that the terminal device can obtain a plurality of screen test display parameter values, and then control the test area to display according to the plurality of screen test display parameter values.
It should be noted that the number of the screen test display parameters may be one or multiple; when the number of the screen test display parameters is multiple, the terminal device can also combine multiple screen test display parameter values corresponding to each screen test display parameter to obtain more groups of screen test display parameter values, and then control the test area to display according to the multiple groups of screen test display parameter values.
It should be noted that, in the process of dividing the value range of each screen test display parameter into a plurality of value intervals, the division can be performed according to the actual accuracy requirement. If the light sensation accuracy required by the terminal equipment is higher, the terminal equipment can divide the value range of each screen test display parameter into more value intervals, and the range of each value interval is smaller; if the light sensation accuracy required by the terminal equipment is low, the terminal equipment can divide the value range of each screen test display parameter into a small number of value intervals, and the range of each value interval is large.
For example, assuming that the screen test display parameter is an RGB value, the value range of the RGB value is (0, 0, 0) - (255, 255, 255), the terminal device divides the value range of the RGB value into 5000 sections according to the light sensation accuracy requirement, and determines a value in each section as the RGB value of the section, so that the terminal device can obtain 5000 RGB values, and at this time, the terminal device can control the test area to display the 5000 RGB values respectively.
Exemplarily, assuming that screen test display parameters are an RGB value and a backlight level, the RGB value ranges from (0, 0, 0) to (255, 255, 255), and the backlight level ranges from 0 to 100 levels; the terminal equipment divides the value range of the RGB value into 5000 intervals according to the light sensation accuracy requirement, and determines a value in each interval as the RGB value of the interval, so that the terminal equipment can obtain 5000 RGB values; similarly, the terminal device divides the value range of the backlight grade into 20 intervals according to the light sensation accuracy requirement, and determines a grade in each interval as the backlight grade of the interval, so that the terminal device can obtain 20 backlight grades; at this time, the terminal device combines 5000 RGB values and 20 backlight levels to obtain 100000 sets of screen test display parameter values, and then the terminal device can control the test area to display according to the 100000 sets of screen test display parameter values respectively.
Through this optional implementation, terminal equipment can divide a plurality of value intervals according to the value range of screen test display parameter to confirm a plurality of screen test display parameter values according to a plurality of value intervals and carry out the light sense and detect, terminal equipment just can gather the corresponding relation between a large amount of screen test light sense values and the screen test display parameter like this, so that terminal equipment can directly use the data of this screen light sense value to calculate in the actual light sense detects, improve terminal equipment to the accuracy that the ambient light intensity detected.
202. And respectively acquiring screen test light sensing values corresponding to each group of screen test display parameter values through the light sensing sensors.
In the embodiment of the invention, the terminal equipment can acquire the current screen test light sensation value through the light sensation sensor when the test area displays according to each group of screen test display parameters.
It should be noted that, the terminal device may first determine the screen test display parameter as a first screen test display parameter value, and then collect a first screen test light sensation value determined by the light sensation sensor; determining the screen test display parameters as second screen test display parameter values, and then collecting second screen test light sensation values determined by the light sensation sensors; by analogy, the terminal equipment can continuously adjust the values of the screen test display parameters, and then the screen test light sensation value corresponding to the value of each screen test display parameter determined by the light sensation sensor is collected.
The first screen test light sensitivity value can be used for indicating the light intensity of the corresponding screen light when the screen display parameter of the test area is the first screen test display parameter value; the second screen test light sensitivity value may be used to indicate the light intensity of the corresponding screen light when the screen display parameter of the test area is the second screen test display parameter value; by analogy, each screen light sensation value can be used for indicating the light intensity of the corresponding screen light when the screen display parameter of the test area is a certain screen test display parameter value.
203. And storing each group of screen test display parameter values and corresponding screen test light sensitivity values in a light sensitivity database.
In the embodiment of the invention, after the terminal device obtains the screen test light sensitivity value, the screen test light sensitivity value and the corresponding screen test display parameter can be correspondingly stored to obtain the light sensation database, so that the terminal device can determine the screen light sensitivity value according to the current screen display parameter value in the actual light sensation detection process.
Alternatively, the format stored in the light sensation database may be (screen test display parameter value, screen test light sensation value).
204. And acquiring an initial light sensation value through the light sensation sensor.
205. And determining a screen display parameter value corresponding to the screen position according to the screen position corresponding to the light sensor.
In the embodiment of the present invention, for the description of the steps 204 to 205, please refer to the detailed description of the steps 101 to 102 in the first embodiment, which is not repeated herein.
Optionally, after the terminal device obtains the initial light sensation value, the state of the automatic backlight function may be detected, which may specifically include but is not limited to the following implementation manners:
the implementation mode is as follows: and under the condition that the automatic backlight function of the screen of the terminal equipment is in an open state, determining a screen display parameter value corresponding to the screen position according to the screen position corresponding to the light sensation sensor.
In this implementation manner, if the terminal device detects that the automatic backlight function of the terminal device is in an on state, the terminal device needs to determine the current accurate ambient light sensitivity value, and therefore the terminal device needs to determine the screen display parameter value to eliminate the influence of the screen light on the light sensor.
It should be noted that the automatic backlight function is a function that the terminal device can automatically adjust the screen brightness, and in general, when the terminal device is in an environment with high brightness, the screen brightness of the terminal device is adjusted to be high, so that the user can clearly see the content displayed on the screen; when the terminal device is in an environment with very low brightness, if the screen brightness of the terminal device is high, the user experience will be influenced, and therefore the screen brightness of the terminal device needs to be reduced so that the user can view the content displayed on the screen more comfortably. In a terminal device without an automatic backlight function, or the terminal device does not start the automatic backlight function, a user is required to manually adjust the screen brightness to adapt to the light intensity of ambient light; when the automatic backlight function of the terminal equipment is started, the terminal equipment can automatically adjust the screen brightness according to the light intensity of the ambient light, and the detection of the terminal equipment on the light intensity of the ambient light is realized through the light sensation sensor, so that the accuracy requirement of the terminal equipment on the light sensation sensor is higher.
The implementation mode two is as follows: and determining the initial light sensation value as the current ambient light sensation value under the condition that the automatic backlight function of the screen of the terminal equipment is in the closed state.
In this implementation, if the terminal device detects that the automatic backlight function of the terminal device is in the off state, the terminal device does not need to detect the screen light sensation value, and also does not need to determine the screen display parameter value, so the terminal device can directly determine the initial light sensation value as the current ambient light sensation value.
