Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Fig. 1 schematically shows a flow chart of a screen control method provided by the present disclosure, where the method includes:
The screen may be any of various display screens, and may be an electronic device having a display function provided in a personal computer, a notebook, a fort machine, or the like. The environment in which the screen is located is the use environment in which the screen is located, and may be inside a house or outside the house, and there is no strict limitation on the use environment as long as the environment in which the screen can be used is used in the embodiments of the present disclosure. The infrared information refers to information related to infrared rays radiated by an object in the environment, such as infrared radiation intensity, infrared receiving direction, and the like, and may be specifically set according to actual requirements, which is not limited herein.
Optionally, the execution subject of some embodiments of the present disclosure may be a screen controller of a screen, where the screen controller is an electronic device for controlling display of the screen, and the screen controller may be separately provided from the screen or integrally provided in the screen.
In this disclosed embodiment, the infrared sensor that the accessible is connected is to the infrared information in the environment of screen place to screen controller can follow infrared sensor and acquire infrared information, and this infrared sensor can be set up on the screen, or establish outside the screen, and all be in same environment with the screen, as long as can be the infrared ray of screen place environment and detect all can be applicable to this disclosed embodiment, and this place does not limit.
And 102, judging whether an intruder heat source other than the user heat source exists in the environment or not according to the infrared information.
In the embodiment of the present disclosure, the user heat source may refer to a user heat source that the screen has authorized to view the screen in advance, and it may be understood that there is a difference in body temperature of different users, so that the user heat source may be identified by analyzing a difference between different heat sources in the collected infrared information. The user heat source can also be a user heat source which is just in front of the screen and is watching the screen, and it can be understood that the user is often watching the screen, and an intruder who snoops the screen is usually at the side of the screen. The user heat source can also be a human heat source previously input by a user, for example, the user can input the user heat source by acquiring own infrared information through an infrared sensor in advance through system configuration, or when the user starts a screen or an electronic device where the screen is located, the system automatically acquires the human heat source in front of the screen through the infrared sensor to serve as the user heat source. Further, the intruder heat source is a user heat source other than the user heat source which is not authorized to view the screen.
Specifically, the screen controller determines whether an intruder heat source exists in the current environment by analyzing the infrared information to identify the human heat source, namely, if any one human heat source is not the user heat source, determining that the intruder heat source exists in the environment where the screen is located, and if all the human heat sources are the user, determining that the intruder heat source does not exist in the environment where the screen is located. It is to be noted that one or more user heat sources may exist, that is, the screen controller may set a plurality of user heat sources as the user heat sources, so that a plurality of users can view the screen at the same time without being snooped by other unauthorized users on the content displayed on the screen.
In the embodiment of the disclosure, the screen controller adjusts the display mode of the active control screen after confirming that the heat source of the intruder exists in the environment. For example, the distance between the intruder and the screen and the distance between the intruder and the user can be calculated according to the infrared information of the intruder, so that the brightness of the screen is adjusted to a brightness range in which only the distance between the user and the screen is visible; the visual range of the screen can be adjusted to a range that is visible only right in front of the screen, so that a user who views only in front of the screen can view the screen display content. Of course, the description is only an exemplary description, and the specific peep-proof display mode may be set according to actual requirements, as long as the function of preventing the intruder from snooping is achieved, and the description is not limited herein.
According to the method and the device, whether the heat source of the intruder except the user exists in the environment is identified by identifying the heat source in the environment according to the infrared information in the environment where the screen is located, so that the screen is automatically controlled to be adjusted to the peep-proof display mode which is only visible for the user after the heat source of the intruder is identified, the screen can be adjusted to the peep-proof display mode in time, the risk that the display content of the screen is seen by the intruder is avoided, and the safety of the display content of the screen is improved.
Optionally, referring to fig. 2, the step 102 includes:
In the embodiment of the present disclosure, the reference human heat source may be obtained by performing feature acquisition on infrared rays emitted by a human body in advance, and it can be understood that since there is a difference in characteristics between infrared rays radiated by different objects, the human heat source is significantly different from the non-human heat source in terms of radiation intensity and radiation range.
The screen controller may perform feature matching on the reference human heat source and the heat source identified in the infrared information, and use a heat source whose feature similarity meets a matching condition, for example, a heat source whose feature similarity is greater than a similarity threshold as the human heat source, or a heat source whose feature similarity is within a similarity threshold range as the human heat source, where a specific manner may be set according to actual needs, and is not limited herein. Because the comparison is only to preliminarily screen out the subsequent human heat sources participating in the user heat source comparison, the comparison precision can be properly widened, and the situation that the human heat sources cannot be identified due to overhigh precision is avoided.
In the implementation of the disclosure, after the screen controller screens out the human heat source through the collected infrared information, the similarity comparison can be performed again on the human heat source and the preset user heat source, and the comparison requirement can be more strict than the screening of the human heat source, so that the accuracy of the identified user heat source is ensured.
According to the embodiment of the disclosure, the heat source of the user in the environment is identified by screening the heat source of the user from the human heat source after the human heat source is screened by referring to human personnel, so that the accuracy of the identification of the heat source of the user is ensured.
Optionally, referring to fig. 3, the step 1022 includes:
In the embodiment of the disclosure, it is considered that the infrared ray is weakened along with the lengthening of the propagation path, so that the closer to the screen, the higher the infrared radiation intensity in the collected infrared information is, and therefore, the infrared radiation intensity of the user who is in the closer range in front of the screen and views the screen is obviously different from the infrared radiation intensity of the intruder who is in the side of the screen or is far from the screen. And then the accessible is in the infrared radiation intensity of the user's heat source of screen short distance viewing screen directly in front and carries out the record in advance to in-service use compares the infrared intensity of different human personnel with the infrared radiation intensity of user's heat source, thereby obtains infrared intensity difference value.
In the embodiment of the present disclosure, the infrared intensity difference value may be a positive value or a negative value, and it can be understood that there is a certain deviation in the probability between the preset user heat source and the actually collected infrared radiation intensity of the user heat source, and the human heat source cannot be completely matched with the preset user heat source, so that whether the human heat source is the user heat source can be determined by analyzing the magnitude of the infrared intensity difference value.
The embodiment of the disclosure compares the infrared radiation intensity of the human heat source and the infrared radiation intensity of the user heat source to identify whether the user heat source exists in the environment, so that the accuracy of user heat source identification is improved.
Optionally, referring to fig. 4, the step 10222 includes:
And 102222, determining that no heat source of the intruder exists in the environment when the infrared intensity difference value is smaller than or equal to the infrared intensity difference threshold value.
In the embodiment of the disclosure, the infrared embedding intensity difference threshold is an infrared radiation difference value which can exist between an actual user heat source allowed by the system and a preset user heat source. It can be understood that a smaller value of the infrared intensity difference indicates a higher probability that the human heat source is the heat source of the user, whereas a larger value of the infrared intensity difference indicates a lower probability that the human heat source is the heat source of the user.
Optionally, the step 103 may include: adjusting the display viewing angle of the screen to only the target display viewing angle of the user.
In the embodiment of the disclosure, the screen controller can change the light-emitting angle of the light-emitting layer of the screen, thereby achieving the effect that the screen display image can only be viewed by the user. Specifically, since a general user is in a viewing angle range of 90 ° to 135 ° right in front of the screen, the display viewing angle can be adjusted to a viewing angle range of 100 ° to 120 °, or a viewing angle range of 90 ° to 120 °, for example, which can be specifically set according to actual requirements, and is not limited herein. According to the embodiment of the disclosure, the content displayed on the screen can only be watched by the user by adjusting the display angle, the risk that the interloper snoops the content on the screen is avoided, and the safety of the content displayed on the screen is improved.
Optionally, the step 103 may include: adjusting the display brightness of the screen to a target display brightness visible only by the user.
The screen controller can adjust the display visual angle of the screen by changing the display brightness of the screen, thereby achieving the effect that the screen display image can only be watched by the user. Specifically, the display brightness of the screen may be adaptively adjusted according to the ambient brightness, so that the higher the ambient brightness is, the higher the screen brightness required when the user can view the screen display image is, and therefore, the screen display brightness may be adjusted to be a brightness which is visible from the screen by 20cm, 25cm, 30cm, and the like according to the ambient brightness, and the specific adjustment mode of the screen brightness may also be set according to actual requirements, which is not limited herein. According to the embodiment of the disclosure, the display brightness of the screen is adjusted to achieve that the content displayed on the screen can only be viewed by the user, so that the risk that the intruder snoops the content of the screen is avoided, and the safety of the content displayed on the screen is improved.
Illustratively, referring to fig. 5, by switching the screen to the peep-proof display mode, the brightness and the display angle of the screen are smaller than those of the normal display mode, so as to achieve the effect of preventing an intruder other than the user from viewing the displayed content of the screen.
Optionally, after the step 103, the method further comprises: and controlling the screen to be restored to a normal display mode when the heat source of the intruder does not exist in the environment.
In the embodiment of the disclosure, the screen controller continuously collects and analyzes the infrared information of the object in the environment after the screen is switched to the peep-proof display mode, and continuously judges whether an intruder exists in the environment through the above method, and when the intruder does not exist in the environment, that is, the heat source of the intruder leaves from the environment, the screen controller automatically switches the screen from the peep-proof display mode to the normal display mode in which the screen displays according to the original configuration. Thereby ensuring that the screen can keep normal display effect when no intruder exists.
