Detailed ways

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

The screen parameter adjustment method, device and equipment according to the embodiments of the present application will be described below with reference to the accompanying drawings.

Wherein, the execution body of the method and apparatus for adjusting screen brightness in the embodiment of the present application may be a terminal device, wherein the terminal device may be a hardware device with a screen such as a mobile phone, a tablet computer, a personal digital assistant, and a wearable device. The wearable device may be a smart bracelet, a smart watch, smart glasses, and the like.

Fig. 1 is a flowchart of a method for adjusting screen parameters according to an embodiment of the present application. As shown in Figure 1, the screen parameter adjustment method includes:

Step 101, acquire the face picture of the current user collected by the front camera when the face recognition is unlocked.

It can be understood that the terminal device has developed from using the front camera to take pictures to being able to use the front camera to unlock. Since the terminal device performs face recognition and unlocking through the front camera, it can obtain the information collected by the front camera on the current user when the face recognition is unlocked. Face pictures.

Step 102, extracting brightness information of the face picture, querying preset control information to obtain ambient brightness information corresponding to the brightness information of the face picture.

In the embodiment of the present application, the brightness information of the face picture may include the sharpness value of the picture, the definition of the picture, the focus metering parameter value of the face area, etc. It can be understood that the brightness value of the face picture is related to The ambient brightness value has a corresponding relationship. For example, the larger the ambient brightness value, the higher the sharpness of the picture may be. For example, the larger the ambient brightness value, the higher the definition of the picture may be. The smaller the focus aperture of the photometry value, etc., thus, the corresponding relationship between the brightness information of the face picture and the environment brightness information is set in advance according to a large amount of experimental data, and after the brightness information of the face picture is extracted, query the preset second control The information acquires ambient brightness information corresponding to the brightness information of the image of the human face, and then adjusts the brightness of the screen according to the ambient brightness information.

It should be noted that in different application scenarios, the method of obtaining the brightness information of the current environment according to the face picture collected by the camera is different. The example is as follows:

In some examples:

Obtain the electrical signal output after the image sensor of the front camera performs photoelectric conversion on the optical signal input by the current preview image, extract the characteristic information of the electrical signal, query the preset first control information to obtain the ambient brightness corresponding to the characteristic information of the electrical signal information.

It should be understood that the front camera is mainly composed of a lens, a photosensitive image sensor, a pre-amplifier synchronization signal generator, a CCD (Charge Coupled Device, Charge Coupled Device) driver, an image signal forming circuit, and a power supply circuit. The main image sensing part of the camera is CCD, which has the characteristics of high sensitivity, small distortion, long life, anti-vibration, anti-magnetic field, small size, no afterimage, etc. CCD can convert light into electric charge and store and transfer electric charge , The stored charge can also be taken out to change the voltage.

The working principle of the front camera is: the object reflects the light, transmits it to the lens, and focuses it on the CCD chip through the lens. The CCD accumulates the corresponding charge according to the intensity of the light, and after periodic discharge, it generates a charge representing a picture. Signal, the photosensitive element used by the image sensor is mainly two kinds of CCD and CMOS. CCD has high resolution and vivid color reproduction, and has become the leading role in digital photography equipment with megapixels, but it is expensive; compared with CCD, CMOS has the characteristics of energy saving and low cost. Moreover, the photosensitive effect of CMOS within a megapixel is completely comparable to that of CCD, so cameras usually use CMOS as the photosensitive element.

That is to say, the image sensor converts the light signal of the collected image into an electrical signal, so that the electrical signal after the photoelectric conversion of the image sensor of the camera has a corresponding relationship with the current ambient brightness, thus, the image sensor of the camera can be obtained. The electrical signal that is output after the optical signal of the current preview image is photoelectrically converted, and then, the control information including the corresponding relationship between the characteristic information of the electrical signal and the ambient brightness information is preset, the characteristic information of the electrical signal is extracted, and the preset control information is queried. Obtain the brightness information of the environment with the electrical signal.

Wherein, the characteristic information of the electrical signal may be a current value, a voltage value, an amplitude value, etc. indicating the strength of the electrical signal, which is not limited here.

Step 103, if the recognized face picture is valid, determine the initial brightness of the screen unlocking according to the brightness information of the current environment, and adjust the screen brightness according to the initial brightness of the screen unlocking.

Specifically, if it is recognized that the face picture is valid, that is, the face picture is a legitimate user, for example, the recognized face picture matches the pre-registered face picture, then it is determined that the recognized face picture is valid, so that the pre-face recognition Unlocking is successful, and at the same time, when the face recognition image is valid, the initial brightness of the screen unlocking is determined according to the brightness information of the current environment, and the screen brightness is adjusted according to the initial brightness of the screen unlocking.

Therefore, in the embodiment of the present application, when performing face recognition unlocking, when the front camera collects face pictures for front unlocking, the brightness information of the current environment can be obtained synchronously. After the unlocking is successful, the The brightness of the screen can be adjusted according to the ambient brightness information obtained when the face is unlocked, so as to provide the user with a visual experience that the brightness of the screen is simultaneously provided when unlocking.

Certainly, in one embodiment of the present application, the face picture (or other non-face picture) collected by the front camera for the current user when the face recognition is unlocked can also be corresponding to environmental brightness information, environmental information (such as shooting Location, shooting scene) and time information (shooting time, shooting season, etc.) Identify and obtain the current environment information, and obtain the corresponding time information by calling the current display time of the terminal device, so as to match the current environment information and time information of the terminal device with the environment information and time information of the stored pictures, when When the matching degree is high, the ambient brightness information corresponding to the matched picture will be used as the current ambient brightness information to adjust the screen brightness. Therefore, it can be obtained directly by matching the environmental information and time information of the previously stored pictures. The brightness information of the current environment improves the adjustment efficiency and flexibility of the screen brightness.

In another embodiment of the present application, since the scene where the user uses the terminal device is relatively fixed, for example, user A usually plays mobile phone after get off work at night. In this scene, in order to further improve the adjustment efficiency of the screen brightness, you can also directly The environmental brightness information of the last screen brightness adjustment is used as the current environmental brightness information, for example, the pictures collected by the relevant cameras are corresponding to the environmental brightness information, environmental information (such as shooting location, shooting scene) and time information (shooting time, shooting season) etc.), so as to identify the current environment information and time information where the terminal device is located, and match the current environment information and time information where the terminal device is located with the environment information and time information of the last stored picture, when When the matching degree is high, the ambient brightness information corresponding to the latest captured picture is used as the current ambient brightness information.

In one embodiment of the present application, due to differences in the perception of the eyes of different users, for example, younger users may prefer brighter screen brightness than older users, and for example, users who have used computers for a long time and those who do not Computer users may need slightly darker users, etc. In order to provide screen brightness adjustment services according to the individual differences of the users, as shown in Figure 2, the above step 103 also includes:

Step 201, acquire user attributes corresponding to face pictures.

Among them, according to different application scenarios, the user attributes corresponding to the face picture include but are not limited to the user's age, user's gender, user's occupation, user's eye medical history, etc.

It should be noted that in different application scenarios, the ways of obtaining user attributes corresponding to face pictures are different. As a possible implementation method, the corresponding relationship between face pictures and user attributes is stored in advance, so that when obtaining the user attributes After the face picture, the corresponding user attributes are matched according to the pre-stored face picture matched with the face.

Step 202, determine the initial brightness of screen unlocking according to user attributes and brightness information of the current environment.

Specifically, after the user attribute is determined, the initial brightness of the screen unlocking is determined according to the user attribute and the brightness information of the current environment. Thus, on the premise of ensuring the initial brightness of the screen unlocking, the individual differences of the user are taken into account, making the screen brightness adjustment easier. Humanization improves user experience.

For example, in determining user attributes based on face pictures, if the user has a history of eye diseases, in order to protect the user's eyes, after the initial brightness of the screen is determined according to the current ambient brightness information, the screen brightness is slightly lowered to avoid damage to the user's eyes. Irritation to user's eyes.

In an embodiment of the present application, due to different applications currently running on the terminal device in actual applications, users may have different preferences for screen brightness. For example, in a video playback application, the user needs to stare at the display screen for a long time , Therefore, the screen needs to be darker to relieve the user's eye irritation. For example, in the music player application, the user does not need to stare at the screen for a long time. Therefore, in order to ensure the clear display of the picture, the screen brightness needs to be higher.

Specifically, as shown in FIG. 3, after adjusting the brightness of the screen according to the initial brightness of screen unlocking, the method further includes:

Step 301, acquiring information about applications currently running on a terminal device.

Specifically, in different application scenarios, the way to obtain the application information currently running on the terminal device includes but is not limited to calling the application running in the foreground through a hook function to identify the application information currently running on the terminal device.

Step 302: Determine the screen reference brightness corresponding to the currently running application information according to the brightness information of the current environment, and adjust the screen brightness according to the screen reference brightness.

Specifically, according to the brightness information of the current environment, the screen reference brightness corresponding to the currently running application information is determined. If the currently running application does not require the user to stare at the screen for a long time, the screen reference brightness The determined screen brightness should be higher or the same. If the currently running application is an application that requires the user to stare at the screen for a long time, the screen reference brightness will be lower than the screen brightness determined directly based on the brightness information of the environment, and then according to the screen reference brightness The brightness of the screen is adjusted, thereby ensuring the user's viewing experience of the currently running application without affecting the viewing experience of the user.

Thus, in the embodiment of the present application, the brightness information of the current environment is obtained according to the face picture collected by the front camera, and then the brightness of the screen is adjusted according to the brightness information of the current environment. In scenarios such as face unlocking, in addition to meeting the needs of the current scene, such as unlocking requirements, you can also make full use of the image information collected by the current front camera to obtain the brightness information of the current environment based on the current image information collected by the current front camera. On the other hand, compared with the prior art, it is necessary to set up a special light sensor to collect the ambient brightness information, this application can obtain the corresponding ambient brightness by multiplexing the functions of the camera that collects the image information, without calling a dedicated The light brightness sensor is used to obtain the current ambient brightness, which not only saves the manufacturing cost of the terminal equipment, but also improves the aesthetics of the terminal equipment, and also reduces the calculation pressure of the processor.

It should be emphasized that, in one embodiment of the present application, the camera that acquires the brightness information of the current environment may be a low-power camera, and the low-power camera may be always on, so as to perform When the screen brightness is adjusted, the brightness information of the current environment can be extracted at any time according to the image information collected by the low-power camera.

Among them, the low-power camera is a device that consumes less energy when running the camera function through the improvement of the circuit structure or the improvement of the working mode. In some examples, the chip in the camera includes multi-directional processing The data output path of image data output by the device uses a camera chip with multiple data transmission paths to replace the existing camera chip with only one data transmission path, which has the advantages of fast photographing speed, low power consumption, and low temperature rise.

In order to more clearly describe the beneficial effects of the screen parameter adjustment method in the embodiment of the present application, the following description will be made in conjunction with its specific application scenario in the embodiment of the present application, as follows:

In an application scenario of this application, when the terminal device is turned on, in order to make the brightness information of the terminal device match the current ambient brightness, the front camera can be turned on, or the sensor of the front camera that is turned on can be used to extract the current preview image The input optical signal undergoes photoelectric conversion to output an electrical signal, extracting the strength of the electrical signal, querying the preset first control information to obtain the environmental brightness information corresponding to the intensity of the electrical signal, and adjusting the screen brightness according to the environmental brightness information .

In one embodiment of the present application, as shown in Figure 4, in order to implement the front face unlock more intuitively, an image preview window may be provided on the screen, when the user previews the image according to the face picture taken by the front camera When the terminal device obtains the image brightness information in the preview screen, it determines to adjust the screen brightness according to the image brightness information. For example, when the image brightness information includes the focus metering value, the larger the aperture in the focus metering value in the preview etc., the lower the current ambient brightness, so that the corresponding relationship between the focus light metering value and the ambient brightness information can be established based on a large amount of experimental data. After obtaining the focus light metering value in the current preview screen, query the above corresponding relationship to obtain the corresponding current Brightness information for the environment.

Therefore, in this embodiment, when other terminal devices realize the front unlock function and call the front camera, they can obtain the brightness information of the current environment synchronously, and then adjust the brightness information of the screen in real time. Compared with the prior art It is not necessary to separately call the light sensor to obtain the brightness information of the current environment before adjusting the screen brightness, which improves the adjustment efficiency of the screen brightness.

To sum up, the screen parameter adjustment method of the embodiment of the present application obtains the face picture collected by the front camera for the current user when the face recognition is unlocked, extracts the brightness information of the face picture, and queries the preset control information acquisition and The brightness information of the face picture corresponds to the environment brightness information. Furthermore, if the recognition of the face picture is valid, the initial brightness of the screen unlocking is determined according to the brightness information of the current environment, and the screen brightness is adjusted according to the initial brightness of the screen unlocking. Thus, the flexibility of adjusting the brightness of the screen is improved, and the cost of adjusting the brightness of the screen is reduced by reducing the acquisition cost of the environment brightness information, and the efficiency of adjusting the brightness of the screen is improved.

In real life, the blue light problem of terminal equipment has always been a hidden danger affecting the eyesight of users. At present, mainstream terminal equipment LED backlight systems mainly use blue LEDs mixed with yellow phosphors to achieve white light. The spectral composition of short-wave blue light in this white light is obvious. In the visible spectrum, the energy carried by short-wave blue light is second only to ultraviolet rays. They not only exist in sunlight, but also exist in large quantities in 3C screens. Long-term excessive blue light exposure will cause unconscious damage to the human eye.

Therefore, in order to avoid damage to human eyes caused by blue light, other screen parameters (eg, color temperature) of the terminal device also need to be adjusted in practical applications.

Specifically, FIG. 5 is a flowchart of a method for adjusting screen parameters according to another embodiment of the present application. As shown in FIG. 5, after the above step 103, the method further includes:

Step 401, acquire the color temperature information of the current environment according to the current image information collected by the camera.

Step 402: Determine the initial color temperature for screen unlocking according to the color temperature information of the current environment, and adjust the screen color temperature according to the initial screen unlocking color temperature.

It should be understood that the screen of the terminal device is mainly composed of RGB three colors superimposed to present different colors, where B is high-energy short-wave blue light. Part of the blue light is filtered out during the color temperature, and the decrease of B will inevitably lead to a decrease in brightness. If too much blue light is filtered out, the brightness of the screen will be very low, and it will be difficult for users to see the screen clearly.

Therefore, in order not to affect the user's viewing when adjusting the screen color temperature, and make the adjustment of the screen color temperature more natural, the current ambient color temperature can also be obtained based on the current image information collected by the camera, such as the composition ratio of RGB based on the current image information. The current ambient color temperature, and then, determine the initial screen unlocking color temperature according to the current environmental color temperature information, and adjust the screen color temperature according to the initial screen unlocking color temperature. Therefore, on the one hand, it is ensured that the color temperature adjustment result of the screen is more in line with the current ambient brightness, and the color temperature is more natural, which does not affect the user's viewing. On the other hand, the color temperature is directly adjusted according to the current image information, and the adjustment efficiency is high.

It should be emphasized that the current image information in the above embodiments may be the latest image information taken by the terminal device, or the image information matching the current scene, or the image information corresponding to the face image captured by the front camera , the principle of acquiring screen parameters based on image information is the same as that of acquiring screen brightness information, and will not be repeated here.

In practical applications, different applications currently running on terminal devices may have different user preferences for color temperature. For example, in video playback applications, users need to stare at the display screen for a long time. Relieve the visual fatigue of the user. For example, in the music playing application, the user does not need to stare at the display screen for a long time. Therefore, in order to ensure the clear display of the picture, the color temperature of the screen needs to be more cooler.

Specifically, to obtain the application information currently running on the terminal device, for example, call the application ID running in the foreground of the current system through the hook function, obtain the application information currently running on the terminal device according to the application ID, and then according to the application information running on the terminal device and the current The color temperature information of the environment adjusts the color temperature of the screen, thereby ensuring the user's viewing experience of the currently running application without affecting the viewing experience of the user.

To sum up, the screen parameter adjustment method of the embodiment of the present application obtains the color temperature information of the current environment according to the current image information collected by the camera, and adjusts the color temperature of the screen according to the color temperature information of the current environment. As a result, the display effect of the screen is more humanized, and the viewing experience of the user is improved.

To achieve the above purpose, the present application also proposes a device for adjusting screen parameters. Fig. 6 is a schematic structural diagram of an apparatus for adjusting screen parameters according to an embodiment of the present application.

Wherein, the third acquiring module 400 is configured to acquire application information currently running on the terminal device.

The adjustment module 300 is further configured to determine a screen reference brightness corresponding to the currently running application information according to the brightness information of the current environment, and adjust the screen brightness according to the screen reference brightness.

It should be noted that the foregoing explanations on the method for adjusting screen parameters are also applicable to the device for adjusting screen parameters in the embodiment of the present application, and the implementation principles thereof are similar, so details are not repeated here.

To sum up, the screen parameter adjustment device of the embodiment of the present application obtains the face picture collected by the front camera for the current user when the face recognition is unlocked, extracts the brightness information of the face picture, and queries the preset control information acquisition and The brightness information of the face picture corresponds to the environment brightness information. Furthermore, if the recognition of the face picture is valid, the initial brightness of the screen unlocking is determined according to the brightness information of the current environment, and the screen brightness is adjusted according to the initial brightness of the screen unlocking. Thus, the flexibility of adjusting the brightness of the screen is improved, and the cost of adjusting the brightness of the screen is reduced by reducing the acquisition cost of the environment brightness information, and the efficiency of adjusting the brightness of the screen is improved.
