As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
In order to explain the technical solution of the present application, the following description will be given by way of specific examples.
When the display screen at terminal is for having the display screen of frame from top to bottom, the upper frame at display screen can be placed to ambient light sensor, and when the display screen at terminal was bang screen form, ambient light sensor can be placed in bang region. However, in both arrangements, when the ambient light sensor is located in the backlight direction, the ambient light intensity detected by the ambient light sensor will be low. For example, as shown in fig. 1, the light source is located on the ceiling, and when the user is lying on the bed to watch the mobile phone, the ambient light sensor is located in the backlight direction, and only the reflected light can be detected, so that the ambient light intensity detected by the ambient light sensor will be lower than the ambient light intensity actually sensed by the user.
In addition, when the ambient light sensor of the terminal is blocked, there is a problem that the ambient light intensity of the environment where the terminal is currently located cannot be accurately detected.
When the display screen of the terminal is a full screen, the ambient light sensor is usually designed to be hidden. For example, for an LCD display screen, the ambient light sensor may be placed in a slit region above the display screen, and for an OLED display screen, the ambient light sensor may be hidden in a manner of being placed under the screen.
However, when the ambient light sensor is placed in the slit region above the display screen for hiding, the slit width is narrow, and the ambient light sensor is far away from the display screen glass cover plate, so that the field angle of the ambient light sensor is slightly small and often smaller than that of human eyes, and therefore, the detected ambient light intensity is easily inconsistent with the human eyes.
Therefore, the current ambient light sensor has a problem of low detection precision when detecting the ambient light intensity, and an error will exist in the brightness adjustment of the display screen.
In the embodiment of the application, a first optical sensor for detecting the ambient illumination intensity of a first side of a terminal and a second optical sensor for detecting the ambient illumination intensity of a second side of the terminal are respectively arranged; when the ambient illumination intensity is detected, a first illumination intensity detected by the first light sensor and a second illumination intensity detected by the second light sensor are obtained, and when the first illumination intensity and the second illumination intensity are not both smaller than a first preset illumination intensity threshold value, the larger value of the first illumination intensity and the second illumination intensity is used as the ambient illumination intensity, that is, when any one light sensor of the terminal is in a backlight state or is shielded, the illumination intensity detected by the other light sensor can be used as the ambient illumination intensity, so that the problem that the detection precision is low when the terminal is in a backlight scene or when one light sensor is shielded is effectively solved. In addition, the second optical sensor is arranged on the side opposite to the display screen, so that the second optical sensor has a sufficient field angle, and the detected ambient illumination intensity is not consistent with the feeling of human eyes because the field angle is smaller than the field angle of human eyes.
Fig. 2 shows a schematic flow chart of an implementation of the method for detecting ambient light intensity provided in the embodiment of the present application, where the method is applied to a terminal, and can be executed by a device configured on the terminal for detecting ambient light intensity, and is suitable for a situation where it is necessary to improve detection accuracy of ambient light intensity. The terminal can be an intelligent terminal such as a mobile phone, a tablet computer, a Personal Computer (PC), a learning machine and the like, and comprises a first optical sensor for detecting the ambient light intensity of a first side of the terminal and a second optical sensor for detecting the ambient light intensity of a second side of the terminal; the first side is the side of the terminal provided with the display screen, and the second side is the side back to the back of the display screen of the terminal.
The method for detecting the ambient light intensity may include steps 201 to 203.
The first optical sensor is used for detecting the ambient light intensity of one side provided with the display screen, and the sensor is an ambient light sensor which is arranged on the traditional terminal and used for detecting the ambient light intensity. Also, the first light sensor may be a light sensor including a photo resistor or a photo diode.
The second optical sensor is an optical sensor for detecting the ambient light intensity on the side opposite to the display screen of the terminal.
In some embodiments of the present application, the second light sensor may be a color temperature sensor.
The color temperature sensor is a light sensor capable of detecting the intensity of ambient light with different wavelengths, and has a plurality of color channels, and the color temperature of the ambient light can be calculated through the spectral information of each channel, so that the color temperature sensor is generally used for detecting the color temperature information of the current environment of the terminal to assist the camera in white balance processing.
However, since the color temperature sensor can calculate not only the color temperature but also the ambient light intensity, in the implementation of the present application, the rear color temperature sensor disposed on the side opposite to the display screen of the terminal may be used as the second light sensor.
That is to say, the original color temperature sensor for detecting the ambient color temperature of the terminal can be used as the second light sensor of the present application, and the ambient illumination intensity on the second side of the terminal can be detected by using the second light sensor, so that the accuracy of detecting the ambient illumination intensity by the terminal can be improved without increasing the hardware structure of the terminal.
In addition, in order to increase the angle of view of the second optical sensor, in some embodiments of the present application, a diffusion film may be added on the second optical sensor to increase the angle of view sensed by the second optical sensor.
In other embodiments of the present application, the second optical sensor may also be an ambient light sensor that is the same as the first optical sensor, or the second optical sensor may also be a camera, and the ambient light intensity of the environment where the terminal is currently located is determined according to the brightness of an image acquired by the camera.
In the embodiment of the application, after the first illumination intensity detected by the first light sensor and the second illumination intensity detected by the second light sensor are obtained, whether the current environment of the terminal is a low-light environment or not can be determined by judging whether the first illumination intensity and the second illumination intensity are both smaller than a first preset illumination intensity threshold value or not.
For example, when both the first illumination intensity and the second illumination intensity are smaller than a first preset illumination intensity threshold, it may be determined that the current environment of the terminal is a low-light environment; and when the first illumination intensity and the second illumination intensity are not both smaller than a first preset illumination intensity threshold value, the current environment of the terminal is considered to be a highlight environment.
Specifically, when only one of the first illumination intensity and the second illumination intensity is lower than the first preset illumination intensity threshold, it may be that one of the first light sensor or the second light sensor is blocked or is in a backlight state, rather than that the current environment of the terminal is a low-light environment. Therefore, in the embodiment of the present application, when both the first illumination intensity and the second illumination intensity are smaller than a first preset illumination intensity threshold, it is determined that the current environment of the terminal is a low-light environment; and when at least one of the first illumination intensity and the second illumination intensity is greater than or equal to the first preset illumination intensity threshold value, determining that the current environment of the terminal is a highlight environment.
The first preset illumination intensity threshold may be set at the time of factory shipment, and may be set according to practical experience.
In this embodiment of the application, when the first illumination intensity and the second illumination intensity are not both smaller than the first preset illumination intensity threshold, that is, when it is determined that the current environment of the terminal is a highlight environment, a larger value of the first illumination intensity and the second illumination intensity is used as the ambient illumination intensity, so as to prevent the user from blocking any one of the light sensors, or when any one of the light sensors is in a backlight scene, the detected ambient illumination intensity is relatively low, and thus the detection accuracy of the ambient illumination intensity is improved.
As shown in fig. 3, in some embodiments of the present application, after the step 202 of determining whether the first illumination intensity and the second illumination intensity are both less than the first preset illumination intensity threshold, the method may include: step 204, if the first illumination intensity and the second illumination intensity are both smaller than a first preset illumination intensity threshold, taking the second illumination intensity as the ambient illumination intensity.
Because the terminal hiding the ambient light sensor in the manner of swinging under the screen is affected by light leakage of the display screen, the illumination intensity detected by the ambient light sensor needs to be calculated by using a related fitting algorithm, and the relatively real ambient illumination intensity can be obtained finally. However, due to the inconsistency of the individual display screens and the error of the fitting algorithm, the ambient light intensity calculated by the fitting algorithm usually has an error. Especially, in a low-light environment, most of the illumination intensity detected by the ambient light sensor is derived from light leakage of the display screen, the accuracy can only be achieved by 30% in this way, and when the actual ambient illumination intensity is 0lux, the ambient illumination intensity detected by the ambient light sensor obtained through final calculation may be 2-3 lux, and when the actual ambient illumination intensity is 2-3 lux, the ambient illumination intensity detected by the ambient light sensor obtained through final calculation may be 0 lux.
In some embodiments of the present application, when above-mentioned first illumination intensity and above-mentioned second illumination intensity are all less than first predetermined illumination intensity threshold value, it is low light environment to show the environment that above-mentioned terminal is located at present, consequently, in order to avoid low light environment, because the display screen light leak leads to the environment illumination intensity that the environment light sensor at terminal detected to have great error, the second illumination intensity that this application will directly set up the second light sensor that carries on the back in the body side with the display screen at terminal detected is as environment illumination intensity to improve the detection precision of terminal environment illumination intensity, and make the luminance adjustment of display screen more accurate.
As shown in fig. 4, in some embodiments of the present application, the method for detecting the intensity of ambient light may further include: step 401 to step 404.
That is, in the embodiment of the present application, it may not be necessary to directly compare the first illumination intensity with the second illumination intensity, and then determine the larger value of the first illumination intensity and the second illumination intensity as the above-mentioned ambient illumination intensity; instead, the first illumination intensity may be directly compared with a second preset illumination intensity threshold to determine whether the first light sensor is backlit or shielded, and when the first illumination intensity is smaller than the second preset illumination intensity threshold, the first light sensor is backlit or shielded, and the second illumination intensity is used as the final ambient illumination intensity.
The second preset illumination intensity threshold may be equal to the first preset illumination intensity threshold, or slightly smaller or slightly larger than the first preset illumination intensity threshold.
Optionally, when the first illumination intensity is greater than or equal to the second preset illumination intensity threshold, it is detected whether the second illumination intensity is less than the second preset illumination intensity threshold, and if the second illumination intensity is less than the second preset illumination intensity threshold, it indicates that the second light sensor is in a backlight state or is shielded, so that the first illumination intensity may be used as the ambient illumination intensity.
In some embodiments of the present application, as shown in fig. 5, the method for detecting the intensity of ambient light may further include: step 501 to step 504.
That is to say, in the embodiment of the present application, it is not necessary to directly compare the first illumination intensity with the second illumination intensity, or it is not necessary to compare the first illumination intensity with a second preset illumination intensity threshold value, so as to determine whether the first light sensor is backlit; but determine whether the first light sensor is in a backlight mode by detecting whether the screen angle of the terminal is within a preset angle range, and determine that the first light sensor is in a backlight state when the screen angle of the terminal is within the preset angle range, so that the second light intensity is used as the final ambient light intensity, thereby avoiding that the detected ambient light intensity has a large error due to the fact that the ambient light sensor is in the backlight state, and improving the detection precision of the ambient light intensity.
The preset angle range is an angle range in which a screen of the terminal faces downwards, and can be set according to practical experience. And, the screen angle of the terminal can be detected by a gravity sensor.
Optionally, in step 503, after detecting whether the screen angle of the terminal is within the preset angle range, the method may further include: and if the screen angle of the terminal is not within a preset angle range, taking the first illumination intensity as the ambient illumination intensity.
That is, since the first light sensor is not in a backlight state and the second light sensor may be in a backlight state, the first illumination intensity may be set as the ambient illumination intensity.
It should be noted that for simplicity of description, the aforementioned method embodiments are all presented as a series of combinations of acts, but those skilled in the art will appreciate that the present invention is not limited by the order of acts described, as some steps may occur in other orders in accordance with the present invention.
