Technical Field
The embodiment of the invention relates to the technical field of electronics, in particular to a screen brightness adjusting method, electronic equipment and a computer readable storage medium.
Background
The screen brightness refers to the physical quantity of the luminous intensity of the surface of the luminous object, namely brightness, which is physically represented by L and has the unit of candela per square meter or lumen. The brightness is an important index for measuring the luminous intensity of the screen, and for the display panel, the high brightness also means higher anti-interference capability to the working environment of the display panel. When people look at the screen, the brightness is higher and better, so that the picture is more gorgeous and the detail performance is more excellent. Therefore, many people feel that the higher the screen brightness, the better. But in fact, the brightness is 500 lumens, and the contrast ratio is more than 600: 1, so that the product can completely meet the requirement of viewing. Excessive pursuit of brightness not only increases the power consumption of the screen, but also causes eye fatigue more easily, and is not beneficial to the protection of eyes.
The inventor finds that at least the following problems exist in the prior art: in obtaining the actual brightness of the current environment, the brightness corresponding to the screen is generally adjusted according to the value obtained by the light sensor. However, when the brightness of the screen is adjusted by the value of the light sensor, the light of the screen itself is also received by the light sensor, so that the value obtained by the light sensor is not the actual brightness of the current environment, and further, the brightness of the screen adjusted by the value of the light sensor is also inaccurate.

Because the detected first photosensitive intensity in the current environment contains the photosensitive intensity generated by the screen, the second photosensitive intensity generated by the screen under the condition of obtaining the current screen brightness is subtracted from the first photosensitive intensity, namely the influence of the brightness generated by the screen on the first photosensitive intensity is eliminated, so that the screen brightness is adjusted only according to the actual brightness of the current environment, and the adjustment on the screen brightness is more accurate.
In addition, the second photosensitive intensity generated by the screen is obtained according to the screen brightness, and the method specifically comprises the following steps: acquiring second photosensitive intensity corresponding to the screen brightness according to a first pre-stored corresponding relation; the first corresponding relation is the corresponding relation between the screen brightness and the photosensitive intensity under the condition of no light. By means of the corresponding relation between the screen brightness and the photosensitive intensity under the dark condition, after the current screen brightness is obtained according to the first photosensitive intensity, the second photosensitive intensity generated by the corresponding screen can be directly obtained according to the screen brightness, and a specific method for obtaining the second photosensitive intensity generated by the screen is provided.
In addition, before acquiring the second photosensitive intensity generated by the screen according to the screen brightness, the method further comprises the following steps: judging whether the face information of the user is detected; if the face information of the user is not detected, acquiring second photosensitive intensity corresponding to the screen brightness through a first corresponding relation stored in advance; if the face information of the user is detected, acquiring second photosensitive intensity generated by the screen according to the screen brightness, specifically: acquiring a second photosensitive intensity corresponding to the screen brightness according to a second corresponding relation stored in advance; the second corresponding relation is the corresponding relation between the screen brightness and the photosensitive intensity under the condition of no light; the light intensity in the second corresponding relationship is a value received by the light sensor after the face of the user affects the brightness of the screen. When the face information of the user is detected, the second photosensitive intensity which influences the screen by the light rays emitted by the screen through the face reflection of the user is eliminated in the first photosensitive intensity, so that the brightness of the screen is adjusted more accurately.
In addition, before acquiring the second photosensitive intensity generated by the screen according to the screen brightness, the method further comprises the following steps: analyzing the color information of the current screen; acquiring second photosensitive intensity generated by the screen according to the screen brightness, specifically: acquiring second photosensitive intensity corresponding to the screen brightness according to a pre-stored fourth corresponding relation; the fourth corresponding relation is the corresponding relation between the screen brightness and the photosensitive intensity under the condition of no light; the photosensitive intensity in the fourth corresponding relationship is a value received by the light sensor after the color information of the screen affects the brightness of the screen.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a screen brightness adjusting method. The core of the embodiment lies in that the light intensity under the current environment is detected as the first light intensity; then, acquiring the current screen brightness according to the first photosensitive intensity; acquiring second photosensitive intensity generated by the screen according to the screen brightness; obtaining the actual photosensitive intensity of the current environment according to the first photosensitive intensity and the second photosensitive intensity; and adjusting the brightness of the screen according to the actual photosensitive intensity. Because the detected first photosensitive intensity in the current environment contains the photosensitive intensity generated by the screen, the second photosensitive intensity generated by the screen under the condition of obtaining the current screen brightness is subtracted from the first photosensitive intensity, namely the influence of the brightness generated by the screen on the first photosensitive intensity is eliminated, so that the screen brightness is adjusted only according to the actual brightness of the current environment, and the adjustment on the screen brightness is more accurate. The implementation details of the method for adjusting screen brightness according to the present embodiment are specifically described below, and the following description is only provided for facilitating understanding of the implementation details, and is not necessary for implementing the present solution.
In the present embodiment, the screen may be a liquid crystal display, or a Light Emitting Diode (LED) display, and the screen brightness adjusting method may adjust the brightness of a mobile phone screen, the brightness of a computer screen, and the like, and the adjustment of the brightness of the mobile phone screen is described as an example below. The specific flow chart is shown in fig. 1, and includes:
step 101, detecting the light intensity under the current environment as a first light intensity.
Specifically, a first light sensing intensity of the screen in the current environment can be obtained through the light sensor. The light sensor is also called a brightness sensor, is generally positioned above a mobile phone screen, can acquire the light brightness of the mobile phone in the current environment, and can automatically adjust the screen brightness of the mobile phone according to the light brightness of the mobile phone in the current environment, so that a better visual effect is brought to a user.
And 102, acquiring the current screen brightness according to the first photosensitive intensity.
Specifically, after the first photosensitive intensity is obtained, the current screen brightness is obtained according to the numerical value of the first photosensitive intensity and corresponding to a form built in the system. In the table, the corresponding relationship between the first photosensitive intensity and the screen brightness is recorded, and as shown in table one, the unit of the first photosensitive intensity is candela (Cd for short), and the unit of the screen brightness is nits (nits). When the value of the first photosensitive intensity is in a certain interval, the screen brightness is the value corresponding to the interval. For example, when the first photosensitive intensity is 800Cd, the lookup table is located in the interval [400, 1000), and the corresponding screen brightness is 70 nits.
| First photosensitive intensity (Cd) | Screen brightness (nits) |
| [0，200) | 25 |
| [200，400) | 55 |
| [400，1000) | 70 |
| [1000，3000) | 90 |
| [3000, infinity) | 250 |
Watch 1
It should be noted that the correspondence between the first photosensitive intensity and the screen brightness in the first table is not limited to this. Because the first sensitization intensity of different types of cell-phones all differs with the corresponding relation of screen luminance, the position that leads to light sensor is also different easily in addition to different cell-phone designs, and light sensor's position is different, can directly influence the first sensitization intensity that light sensor received. Therefore, different types of mobile phones require different corresponding relationships, and if the mobile phones are universal, the accuracy of screen brightness adjustment is affected to a certain extent.
And 103, acquiring a second photosensitive intensity generated by the screen according to the screen brightness.
Specifically, the second photosensitive intensity corresponding to the screen brightness can be obtained through the first corresponding relation stored in advance. Here, the second photosensitive intensity is the second photosensitive intensity at the current screen brightness obtained in the absence of light. Because the periphery of the mobile phone is dark and lightless under the lightless condition, the value of the light sensor is only the photosensitive intensity obtained by the brightness of the screen, namely the second photosensitive intensity generated by the screen. The first correspondence relationship here is a correspondence relationship formed by adjusting each luminance of the screen in the absence of light to obtain a light-sensitive intensity corresponding to the luminance.
And 104, obtaining the actual photosensitive intensity of the current environment according to the first photosensitive intensity and the second photosensitive intensity.
That is, the second photosensitive intensity that affects the accuracy of the first photosensitive intensity is excluded, that is, the second photosensitive intensity is subtracted from the first photosensitive intensity, so as to obtain the actual photosensitive intensity of the current environment.
And 105, adjusting the brightness of the screen according to the actual photosensitive intensity.
And adjusting the brightness of the screen according to the obtained actual photosensitive intensity, wherein the actual photosensitive intensity is the actual photosensitive intensity without the influence of the brightness generated by the screen on the first photosensitive intensity.
Compared with the prior art, the method for adjusting the screen brightness provided by the embodiment detects the photosensitive intensity in the current environment as the first photosensitive intensity; then, acquiring the current screen brightness according to the first photosensitive intensity; acquiring second photosensitive intensity generated by the screen according to the screen brightness; obtaining the actual photosensitive intensity of the current environment according to the first photosensitive intensity and the second photosensitive intensity; and adjusting the brightness of the screen according to the actual photosensitive intensity. Because the detected first photosensitive intensity in the current environment contains the photosensitive intensity generated by the screen, the second photosensitive intensity generated by the screen under the condition of obtaining the current screen brightness is subtracted from the first photosensitive intensity, namely the influence of the brightness generated by the screen on the first photosensitive intensity is eliminated, so that the screen brightness is adjusted only according to the actual brightness of the current environment, and the adjustment on the screen brightness is more accurate.
The second embodiment of the invention relates to a screen brightness adjusting method. The embodiment is a further improvement on the basis of the first embodiment, and the specific improvement is as follows: in the embodiment, before the second photosensitive intensity generated by the screen is acquired according to the screen brightness, whether the face information of the user is detected or not is judged; if the face information of the user is not detected, acquiring second photosensitive intensity corresponding to the screen brightness through a first corresponding relation stored in advance; and if the face information of the user is detected, acquiring a second photosensitive intensity corresponding to the screen brightness through a second corresponding relation stored in advance. Because the light intensity in the second corresponding relation is the value received by the light sensor after the face of the user influences the brightness of the screen, the second light intensity influencing the screen is eliminated by reflecting the light emitted by the screen to the screen through the face of the user in the first light intensity, so that the regulation of the screen brightness is more accurate. The specific flow chart is shown in fig. 2, and includes:
step 201, detecting the light sensing intensity in the current environment as a first light sensing intensity.
And step 202, acquiring the current screen brightness according to the first photosensitive intensity.
Since in the present embodiment, steps 201 to 202 are substantially the same as steps 101 to 102 in the first embodiment, the photosensitive intensity in the current environment is intended to be detected as the first photosensitive intensity; and obtaining the current screen brightness according to the first photosensitive intensity, which is not described herein again.
Step 203, determining whether the face information of the user is detected. If the face information of the user is not detected, step 204 is entered; otherwise, step 205 is entered.
Specifically, the face information of the user may be detected by a distance sensor. Since the distance between the face of the user and the mobile phone is about 25 cm to 40 cm when the user uses the mobile phone in general. Therefore, it is preferable that the face information of the user is determined to be detected if the distance between the detected face of the user and the mobile phone is between 25 cm and 40 cm.
And 204, acquiring a second photosensitive intensity corresponding to the screen brightness through a first corresponding relation stored in advance.
Specifically, the second photosensitive intensity here is the second photosensitive intensity at the current screen brightness obtained in the absence of light. Because the periphery of the mobile phone is dark and lightless under the lightless condition, the value of the light sensor is only the photosensitive intensity obtained by the brightness of the screen, namely the second photosensitive intensity generated by the screen. The first correspondence relationship here is a correspondence relationship formed by adjusting each luminance of the screen in the absence of light to obtain a light-sensitive intensity corresponding to the luminance.
Step 205, obtaining a second photosensitive intensity corresponding to the screen brightness through a second pre-stored correspondence.
Specifically, the second photosensitive intensity is a second photosensitive intensity in which light emitted from the screen passes through the face of the user and is reflected to the screen in the absence of light, thereby affecting the light sensor. The second correspondence is a correspondence between the screen brightness and the light-sensitive intensity in the absence of light, and the light-sensitive intensity in the second correspondence is a value received by the light sensor after the face of the user has an influence on the brightness of the screen.
And step 206, obtaining the actual photosensitive intensity of the current environment according to the first photosensitive intensity and the second photosensitive intensity.
And step 207, adjusting the brightness of the screen according to the actual photosensitive intensity.
Since in this embodiment, steps 206 to 207 are substantially the same as steps 104 to 105 in the first embodiment, and are intended to obtain the actual photosensitive intensity of the current environment according to the first photosensitive intensity and the second photosensitive intensity; and adjusting the brightness of the screen according to the actual photosensitive intensity, which is not described herein again.
Compared with the prior art, the method for adjusting the screen brightness provided by the embodiment judges whether the face information of the user is detected or not before the second photosensitive intensity generated by the screen is acquired according to the screen brightness; if the face information of the user is not detected, acquiring second photosensitive intensity corresponding to the screen brightness through a first corresponding relation stored in advance; and if the face information of the user is detected, acquiring a second photosensitive intensity corresponding to the screen brightness through a second corresponding relation stored in advance. Because the light intensity in the second corresponding relation is the value received by the light sensor after the face of the user influences the brightness of the screen, the second light intensity influencing the screen is eliminated by reflecting the light emitted by the screen to the screen through the face of the user in the first light intensity, so that the regulation of the screen brightness is more accurate.
The third embodiment of the present invention relates to a method for adjusting screen brightness, which is further improved based on the first embodiment, and the specific improvements are as follows: in the embodiment, before the second photosensitive intensity generated by the screen is acquired according to the screen brightness, whether the face information of the user is detected or not is judged; if the face information of the user is not detected, acquiring second photosensitive intensity corresponding to the screen brightness through a first corresponding relation stored in advance; and if the face information of the user is detected, acquiring a second photosensitive intensity corresponding to the screen brightness through a pre-stored third corresponding relation. Because the light sensing intensity in the third corresponding relation is a numerical value received by the light sensor after the position of the user relative to the screen and the skin color of the user influence the brightness of the screen, the second light sensing intensity which influences the brightness of the screen by the position of the user relative to the screen and the skin color of the user is eliminated from the first light sensing intensity, and the brightness of the screen is adjusted more accurately. The specific flow chart is shown in fig. 3.
Step 301, detecting the light sensing intensity in the current environment as a first light sensing intensity.
And 303, acquiring the current screen brightness according to the first photosensitive intensity.
Since steps 301 to 302 in the present embodiment are substantially the same as steps 101 to 102 in the first embodiment, the photosensitive intensity in the current environment is intended to be detected as the first photosensitive intensity; and obtaining the current screen brightness according to the first photosensitive intensity, which is not described herein again.
Step 303, judging whether the face information of the user is detected; if it is determined that the face information of the user is not detected, go to step 304; otherwise, step 305 is entered.
Specifically, the face information of the user may be detected by a distance sensor. Since the distance between the face of the user and the mobile phone is about 25 cm to 40 cm when the user uses the mobile phone in general. Therefore, it is preferable that the face information of the user is determined to be detected if the distance between the detected face of the user and the mobile phone is between 25 cm and 40 cm.
Step 304, obtaining a second photosensitive intensity corresponding to the screen brightness through a pre-stored first corresponding relationship, wherein the first corresponding relationship is a corresponding relationship between the screen brightness and the photosensitive intensity under a no-light condition.
Step 305, acquiring the position of the user relative to the screen and the skin color of the user.
Specifically, the position information of the user relative to the screen can be acquired through the distance sensor and the direction sensor, and the skin color of the user can be acquired through the color sensor. Because the positions of the users relative to the screen are different, the second light-sensitive intensities received by the light sensor and reflected to the screen through the face of the user are different, and therefore the positions of the users relative to the screen are considered, and the adjustment of the screen brightness is more accurate. Similarly, the second photosensitive intensities received by the light sensor and reflected to the screen by the skin colors of different users are different, so that the position of the user relative to the screen is considered, and the adjustment of the screen brightness is more accurate.
And step 306, acquiring a second photosensitive intensity corresponding to the screen brightness through a pre-stored third corresponding relation.
Specifically, the third correspondence is a correspondence between screen brightness and light-sensitive intensity in a no-light condition, where the light-sensitive intensity in the third correspondence is a numerical value received by the light sensor after the user's position relative to the screen and the user's skin color affect the screen brightness.
And 307, obtaining the actual photosensitive intensity of the current environment according to the first photosensitive intensity and the second photosensitive intensity.
And 308, adjusting the brightness of the screen according to the actual photosensitive intensity.
Since in this embodiment, steps 307 to 308 are substantially the same as steps 104 to 105 in the first embodiment, the actual photosensitive intensity of the current environment is obtained according to the first photosensitive intensity and the second photosensitive intensity; and adjusting the brightness of the screen according to the actual photosensitive intensity, which is not described herein again.
Compared with the prior art, the method for adjusting the screen brightness provided by the embodiment judges whether the face information of the user is detected or not before the second photosensitive intensity generated by the screen is acquired according to the screen brightness; if the face information of the user is not detected, acquiring second photosensitive intensity corresponding to the screen brightness through a first corresponding relation stored in advance; and if the face information of the user is detected, acquiring a second photosensitive intensity corresponding to the screen brightness through a pre-stored third corresponding relation. Because the light sensing intensity in the third corresponding relation is a numerical value received by the light sensor after the position of the user relative to the screen and the skin color of the user influence the brightness of the screen, the second light sensing intensity which influences the brightness of the screen by the position of the user relative to the screen and the skin color of the user is eliminated from the first light sensing intensity, and the brightness of the screen is adjusted more accurately.
The fourth embodiment of the present invention relates to a method for adjusting screen brightness, which is further improved based on the first embodiment, and the specific improvements are as follows: before acquiring second photosensitive intensity generated by the screen according to the screen brightness, analyzing the color information of the current screen; and acquiring second photosensitive intensity generated by the screen according to the screen brightness, and specifically acquiring the second photosensitive intensity corresponding to the screen brightness through a fourth corresponding relation stored in advance. The photosensitive intensity in the fourth corresponding relation is a value received by the light sensor after the color information of the screen affects the brightness of the screen. The second photosensitive intensity which influences the screen by the color is eliminated from the first photosensitive intensity, so that the brightness of the screen is adjusted more accurately. The specific flow chart is shown in fig. 4.
Step 401, detecting the light sensing intensity in the current environment as a first light sensing intensity.
And 402, acquiring the current screen brightness according to the first photosensitive intensity.
Since steps 401 to 402 in the present embodiment are substantially the same as steps 101 to 102 in the first embodiment, the photosensitive intensity in the current environment is detected as the first photosensitive intensity; and obtaining the current screen brightness according to the first photosensitive intensity, which is not described herein again.
In step 403, the color information of the current screen is analyzed.
Specifically, the three primary colors in the current screen may be recognized by the color sensor and the ratio of the three primary colors in the current screen may be analyzed. Wherein, the three primary colors are respectively red, green and blue, and the brightness of the red is the highest. Because the influence of the brightness of different colors on the light sensor is different, the influence of the three colors on the light sensor under the proportion is obtained by counting the proportion of the three colors, so that the second photosensitive intensity is obtained, and the adjustment of the screen brightness is more accurate.
And step 404, acquiring a second photosensitive intensity corresponding to the screen brightness according to a pre-stored fourth corresponding relation.
Specifically, the fourth correspondence is a correspondence between screen brightness and light-sensitive intensity in the absence of light. The photosensitive intensity in the fourth corresponding relationship is a numerical value received by the light sensor after the color information of the screen affects the brightness of the screen.
And 405, obtaining the actual photosensitive intensity of the current environment according to the first photosensitive intensity and the second photosensitive intensity.
And 406, adjusting the brightness of the screen according to the actual photosensitive intensity.
