Description

Technical Field

[0001] The present disclosure relates to the field of computer technologies, and in particular, to a screen control method, apparatus, electronic device, and storage medium. Background Art

[0002] With the development of computer technologies, the brightness, color temperature, etc. of the screens of more and more electronic devices can be adjusted, so that users feel more comfortable when viewing the screens. When each electronic device works independently, it adjusts the brightness, color temperature, etc. of the screen according to the light conditions in the environment where it is located. However, when there is a certain distance between the position of the user and the position of the electronic device, there will be a difference between the light conditions perceived by the user and the light conditions detected by the electronic device. If the electronic device still adjusts according to the detected light conditions, the adjustment will not be accurate enough, which affects the display effect of the electronic device and the user experience is poor.

[0087] Figure 9 is a block diagram of an electronic device shown according to an exemplary embodiment. Detailed Description of the Invention

[0088] Here, exemplary embodiments will be described in detail, and examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0089] In the related art, when each electronic device works independently, it adjusts the brightness, color temperature, etc. of the screen according to the light conditions in the environment. When there is a certain distance between the position of the user and the position of the electronic device, there will be a difference between the light conditions perceived by the user and the light conditions detected by the electronic device. If the electronic device still adjusts according to the detected light conditions, the adjustment will not be accurate enough, affecting the display effect of the electronic device and resulting in a poor user experience.

[0090] See Figure 1Schematic diagram of the application scenario shown. Taking an electronic device as a TV as an example, when a user is watching TV, the light source is located around the user, and the light source is relatively far from the TV. In this case, the actual light condition perceived by the user is significantly different from the light condition detected by the TV. For the light condition perceived by the user, when a mobile phone is located around the user, the light condition detected by the mobile phone can be used to represent the light condition perceived by the user. For example, the user is holding a mobile phone in their hand, and the mobile phone detects that the ambient illuminance is 200 lux (lux) and the color temperature is 6500 K (Kelvin). The TV is 2 meters away from the user, and the TV detects that the ambient illuminance is 100 lux and the color temperature is 10000 K. It can be seen that the ambient illuminance and color temperature detected by the TV are significantly different from those perceived by the user. When the TV adjusts the screen according to the detected ambient illuminance and color temperature, it cannot be correctly synchronized with the user's perception, which will cause discomfort to the human eye and a poor user experience.

[0091] Embodiments of the present disclosure address the above problems and provide a screen control method, that is, based on the first environmental parameters detected by the first device, to adjust the screen display of the second device. Among them, the first device can be a device relatively close to the user, such as a mobile phone, a tablet computer, a laptop computer, a wearable device, etc., and the second device is a device relatively far from the user, such as a TV, a laptop computer, a display screen, etc. The first device and the second device are in the same environment, and the first device and the second device are connected by a wireless connection method. For example, the first device and the second device are connected by Bluetooth, or by a local area network connection, or by a WiFi (Wireless Fidelity) connection, etc.

[0092] Figure 2 is a flowchart of a screen control method shown according to an exemplary embodiment, executed by the first device. Refer to Figure 2 and the method includes the following steps:

[0093] Step S201, obtain the first environmental parameters collected by the first device, where the first environmental parameters are used to represent the light condition detected by the first device.

[0094] Among them, the first environmental parameters are the environmental parameters collected by the first device and are used to represent the light condition detected by the first device. The first environmental parameters may include the first ambient illuminance and the first color temperature. Of course, the first environmental parameters may also include other parameters representing the light condition.

[0095] In some embodiments, the first device includes a first photosensitive sensor, and the first device collects the first environmental parameters through the first photosensitive sensor. Among them, the number of the first photosensitive sensors is one or more.

[0096] Step S202, determine the screen control parameters based on the first environmental parameters.

[0097] Among them, the screen control parameter is used to adjust the screen display of the device. For example, it can adjust the brightness, color temperature, etc. of the device's screen.

[0098] In some embodiments, based on the first environmental parameter and the preset mapping relationship, the screen control parameter is determined; the preset mapping relationship is used to represent the mapping relationship between the environmental parameter and the screen control parameter. For example, the preset mapping relationship is: screen control parameter = first environmental parameter * preset coefficient.

[0099] Optionally, for different environmental parameters, the preset mapping relationships are different. For example, when the first environmental parameter includes the first environmental illuminance, the screen control parameter includes the brightness control parameter. Based on the first environmental parameter and the preset mapping relationship, determining the screen control parameter includes: based on the first environmental illuminance and the first preset mapping relationship, determining the brightness control parameter, and the first preset mapping relationship is used to represent the mapping relationship between the environmental illuminance and the brightness control parameter. When the first environmental parameter includes the first color temperature, the screen control parameter includes the color temperature control parameter. Based on the first environmental parameter and the preset mapping relationship, determining the screen control parameter includes: based on the first color temperature and the second preset mapping relationship, determining the color temperature control parameter, and the second preset mapping relationship is used to represent the mapping relationship between the color temperature and the color temperature control parameter.

[0100] Of course, other methods can also be used to calculate the screen control parameter based on the first environmental parameter.

[0101] Step S203: Send the screen control parameter to the second device. The screen control parameter is used to adjust the screen display of the second device; among them, the first device, the second device, and the user are at different positions in the same environment, and the first distance between the first device and the user is less than the second distance between the second device and the user.

[0102] In the embodiments of the present disclosure, when the first distance between the first device and the user is less than the second distance between the second device and the user, it means that the first device is closer to the user and the second device is farther from the user. The first environmental parameter collected by the first device can more accurately represent the lighting situation perceived by the user. Therefore, when it is necessary to adjust the screen display of the second device, the first device sends the screen control parameter to the second device, so that the second device adjusts based on the screen control parameter, thereby making the screen display of the second device more in line with the user's perception.

[0103] For the adjustment of the screen display, when the screen control parameter includes the brightness control parameter and the color temperature control parameter, the second device adjusts the brightness of the second device's screen based on the brightness control parameter and adjusts the color temperature of the second device's screen based on the color temperature control parameter.

[0104] It should be noted that for the first device, the first device can use the screen control parameter to adjust the screen display of the first device. The first device can also calculate other screen control parameters based on the first environmental parameter and use other implementation manners to adjust the screen display of the first device. The embodiments of the present disclosure do not limit the adjustment of the screen display of the first device.

[0105] In the method provided by the embodiments of the present disclosure, in the same environment, when the distance between the user and the first device is less than the distance between the user and the second device, it indicates that the first environmental parameter collected by the first device at this time is more in line with the light condition actually perceived by the user. Therefore, based on the first environmental parameter, the screen control parameter is determined, and then the screen control parameter is sent to the second device, so that the second device adjusts the screen display based on the screen control parameter. Thus, through this cross-device screen control method, the screen display effect of the second device is better, more in line with the user's perception, and the user experience is improved.

[0106] Figure 3 is a flowchart of a screen control method shown according to an exemplary embodiment, which is executed by the second device. Refer to Figure 3 The method includes the following steps:

[0107] Step S301: Receive the screen control parameter sent by the first device. The screen control parameter is determined by the first device based on the first environmental parameter collected. The first environmental parameter is used to characterize the light condition detected by the first device. The first device, the second device, and the user are at different positions in the same environment, and the first distance between the first device and the user is less than the second distance between the second device and the user.

[0108] Step S302: Adjust the screen display of the second device based on the screen control parameter.

[0109] For the implementation manners of step S301 and step S302, refer to the implementation manners of the above steps S201 - S203, which will not be elaborated here.

[0110] In the method provided by the embodiments of the present disclosure, in the same environment, when the distance between the user and the first device is less than the distance between the user and the second device, it indicates that the first environmental parameter collected by the first device at this time is more in line with the light condition actually perceived by the user. Therefore, the second device receives the screen control parameter sent by the first device and adjusts the screen display based on the screen control parameter. The screen control parameter is determined by the first device based on the first environmental parameter. Thus, through this cross-device screen control method, the screen display effect of the second device is better, more in line with the user's perception, and the user experience is improved.

[0111] In some embodiments, in addition to the first device collecting the first environmental parameter, the second device also collects the second environmental parameter, and then determines the screen control parameter based on the first environmental parameter and the second environmental parameter. In one example, referring to Figure 4 the schematic diagram of the multi-device interaction process shown in Figure 5 , the first device and the second device respectively collect the first environmental parameter and the second environmental parameter, and then the first device and the second device adjust the screen display through interaction. The following uses

[0112] Figure 5 a flowchart of a screen control method shown according to an exemplary embodiment, which is executed by the first device and the second device, referring to Figure 5 , and the method includes the following steps:

[0113] Step S501, the first device collects the first environmental parameter.

[0114] For the implementation manner of step S501, refer to the above step S201, and details are not described herein again.

[0115] Step S502, the second device collects the second environmental parameter and sends the second environmental parameter to the first device.

[0116] Among them, the second environmental parameter is the environmental parameter collected by the second device, which is used to characterize the light condition detected by the second device. The second environmental parameter may include the second environmental illuminance and the second color temperature. Of course, the second environmental parameter may also include other parameters characterizing the light condition.

[0117] In some embodiments, the second device includes a second photosensitive sensor, and the second device collects the second environmental parameter through the second photosensitive sensor. Among them, the number of the second photosensitive sensors is one or more.

[0118] Step S503, the first device receives the second environmental parameter sent by the second device.

[0119] Step S504, the first device determines the first distance between the first device and the user, and the second distance between the second device and the user.

[0120] In the embodiments of the present disclosure, considering that if the user is far from the first device and close to the second device, the second environmental parameter collected by the second device is closer to the user's perception than the first environmental parameter collected by the first device. Therefore, when the first distance is less than the second distance, the screen display of the second device needs to be adjusted based on the first environmental parameter of the first device.

[0121] In some embodiments, grip data and a first image are collected based on a first device. The grip data is used to characterize whether a user is gripping the first device. Based on the grip data and / or the first image, a first distance between the first device and the user is determined. Among them, the grip data is collected based on a gravity sensor of the first device, and the first image is collected by an imaging module of the first device. Optionally, when the grip data characterizes that the user is gripping the first device, the first distance between the first device and the user is determined to be 0. When the grip data characterizes that the user is not gripping the first device, based on whether the first image includes the user, the first distance between the first device and the user is determined. For example, when the imaging module collects the first image, it can directly determine the distance between the imaging module and the object being collected (the user), and determine this distance as the first distance. Also, for example, the closer the first device is to the user, the fewer body parts of the user are included in the first image collected. If only a small part of the user's body is included in the first image, the first distance is determined to be smaller; or if most of the user's body is included in the first image, the first distance is determined to be larger.

[0122] In some embodiments, based on a second image, a second distance between a second device and the user is determined. Among them, the second image is captured by the first device and includes the user and the second device. In this case, the second distance is determined according to the distance between the user and the second device in the second image. Or when the imaging module of the first device collects the second image, it directly determines the distance between the imaging module and the user being collected, and the distance between the imaging module and the second device being collected, and then determines the second distance based on these two distances. Or, the second image is captured by the second device and includes the user. In this case, when the imaging module of the second device collects the second image, it directly determines the distance between the imaging module of the second device and the user being collected, and uses this distance as the second distance.

[0123] In the embodiments of the present disclosure, when the first distance is less than the second distance, step S505 is executed. When the first distance is not less than the second distance, subsequent steps are no longer executed.

[0124] Step S505: When the first distance is less than the second distance, the first device determines a screen control parameter based on a first environmental parameter and a second environmental parameter, and sends the screen control parameter to the second device.

[0125] In some embodiments, the first environmental parameter includes the first environmental illuminance, the second environmental parameter includes the second environmental illuminance, the screen control parameter includes a brightness control parameter, and the brightness control parameter is used to adjust the brightness of the screen of the second device. Based on the first environmental parameter and the second environment, the screen control parameter is determined, including: determining the difference between the first environmental illuminance and the second environmental illuminance; when the difference is greater than the first threshold, determining the brightness control parameter based on the first environmental illuminance; when the difference is less than or equal to the first threshold, determining the brightness control parameter based on the second environmental illuminance. Wherein, the difference is used to characterize the degree of difference between the first environmental illuminance and the second environmental illuminance. Optionally, the difference can directly be the difference between the first environmental illuminance and the second environmental illuminance. In this case, the first threshold is a preset value of an environmental illuminance. Or, the difference can be the ratio of the difference between the first environmental illuminance and the second environmental illuminance to the second environmental illuminance or the first environmental illuminance. In this case, the first threshold is a preset percentage value.

[0126] When the difference is greater than the first threshold, it indicates that the difference between the second environmental illuminance and the first environmental illuminance is relatively large, and the brightness control parameter needs to be determined based on the first environmental illuminance. When the difference is less than or equal to the first threshold, it indicates that the difference between the second environmental illuminance and the first environmental illuminance is relatively small, and the brightness control parameter can be directly determined based on the second environmental illuminance.

[0127] Of course, in some embodiments, regardless of the difference between the first environmental illuminance and the second environmental illuminance, the brightness control parameter can be directly determined based on the first environmental illuminance; or, the brightness control parameter can also be determined based on the average environmental illuminance of the first environmental illuminance and the second environmental illuminance.

[0128] In some embodiments, the brightness control parameter is determined based on the second distance and the first environmental illuminance; wherein, the brightness control parameter has a positive correlation with the second distance. That is to say, the farther the distance between the user and the second device, in order to allow the user to clearly see the screen of the second device, the greater the brightness of the screen of the second device needs to be. Therefore, the intensity control parameter is determined based on the second distance and the second environmental illuminance. Optionally, based on the second distance, a target ratio is determined, and the target ratio has a positive correlation with the second distance. The first environmental illuminance is increased by the target ratio to determine the third environmental illuminance, and the brightness control parameter is determined based on the third environmental illuminance. For example, if the second distance is 2 meters, the target ratio is 20%. The first environmental illuminance is increased by 20%, that is, the first environmental illuminance * 120% to obtain the third environmental illuminance. For example, if the first environmental illuminance is 200 lux and the second environmental illuminance is 150 lux, the brightness control parameter is determined based on 240 lux.

[0129] In some embodiments, the first environmental parameter includes a first color temperature, the second environmental parameter includes a second color temperature, the screen control parameter includes a color temperature control parameter, and the color temperature control parameter is used to adjust the color temperature of the screen of the second device. Considering that the color temperature closer to the user is more accurate, therefore, based on the first environmental parameter and the second environment, the screen control parameter is determined, including: determining the color temperature control parameter based on the first color temperature. For example, if the first color temperature is 6500K and the second color temperature is 10000K, then the color temperature control parameter is determined based on 6500K.

[0130] In another embodiment, a third image including a light source and a user is collected based on the first device; based on the third image, a third distance between the light source and the user is determined; when the third distance is less than a second threshold, the screen control parameter is determined based on the first environmental parameter. That is to say, when the user is relatively close to the light source, the influence of the distance between the user and the first device and the second device is considered, while when the user is relatively far from the light source, the influence of the distance between the user and the first device and the second device is no longer considered.

[0131] Optionally, the third distance is determined according to the distance between the user and the light source in the third image, or when the camera module of the first device collects the third image, the distance between the camera module and the collected user and the distance between the camera module and the collected light source are directly determined, and then the third distance is determined according to these two distances.

[0132] It should be noted that the embodiments of the present disclosure are only described by taking into account the distance between the user and the first device and the second device as an example. In another embodiment, after receiving the second environmental parameter, the first device can directly determine the screen control parameter based on the first environmental parameter and the second environmental parameter, without determining whether the first distance is less than the second distance.

[0133] Step S506, the second device receives the screen control parameter sent by the first device.

[0134] Step S507, the second device adjusts the screen display of the second device based on the screen control parameter.

[0135] When receiving the screen control parameter, the second device directly adjusts the screen display of the second device based on the screen control parameter.

[0136] In an example, refer to Figure 6The flowchart of the screen control method shown. Taking the first device as a mobile phone and the second device as a TV as an example, the mobile phone and the TV discover each other and add each other through a wireless connection method respectively. Then the mobile phone detects the surrounding environment based on its own photosensitive sensor to obtain the first environmental parameter; the TV detects the surrounding environment based on its own photosensitive sensor to obtain the second environmental parameter; then it is determined whether the mobile phone is located around the user. If the mobile phone is not located around the user, no subsequent operations are performed. If the mobile phone is located around the user, the mobile phone determines the screen control parameters (brightness, color temperature) based on the collected first environmental parameter and the second environmental parameter collected by the TV, and sends the screen control parameters to the TV through a wireless transmission method. The TV adjusts the screen display according to the obtained screen control parameters.

[0137] It should be noted that the above embodiments are only described by taking the second device as an example that can collect the second environmental parameter. In another embodiment, when the second device does not have the function of collecting the second environmental parameter, the first device directly determines the screen control parameter based on the first environmental parameter.

[0138] In the method provided by the embodiments of the present disclosure, in the same environment, when the distance between the user and the first device is less than the distance between the user and the second device, it means that the first environmental parameter collected by the first device at this time is more in line with the actual light situation perceived by the user. Therefore, based on the first environmental parameter, the screen control parameter is determined, and then the screen control parameter is sent to the second device, so that the second device adjusts the screen display based on the screen control parameter. Thus, through this cross-device screen control method, the screen display effect of the second device is better, more in line with the user's perception, improving the user experience and making the user more comfortable to watch.
