Description

Method for automatically adjusting display parameters of a display screen in a vehicle interior
Technical Field
The present disclosure relates to methods, systems, devices, storage media, and program products for automatically adjusting display parameters of a display screen inside a vehicle.
Background
In some vehicles (especially high-end vehicles), a large display screen and a matched cinema system are sometimes arranged at the rear row of the vehicle, so that an experience similar to a private cinema is created for passengers at the rear row. When a display screen in the rear row of a vehicle plays video, for example, ambient light (e.g., sunlight, lights, etc.) around the display screen may have an impact on the user's viewing of the display screen. For example, when the illumination intensity of the ambient light is too large, it may cause a viewer to fail to see the picture played in the display screen.

Detailed Description
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the described exemplary embodiments. It will be apparent, however, to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In the described exemplary embodiments, well known structures or processing steps have not been described in detail in order to avoid unnecessarily obscuring the concepts of the present disclosure.

It will be appreciated by those skilled in the art that the blocks described in each block diagram may be combined or divided into sub-blocks to implement the principles of the present disclosure.
The steps of the methods presented in this disclosure are intended to be illustrative. In some embodiments, the method may be accomplished with one or more additional steps not described and/or without one or more of the steps discussed. Furthermore, the order in which the steps of a method are illustrated and described is not intended to be limiting.
First, a system for automatically adjusting display parameters of a display screen inside a vehicle according to some embodiments of the present disclosure will be described with reference to fig. 1.
Fig. 1 is an exemplary block diagram of a system 100 for automatically adjusting display parameters of a display screen inside a vehicle according to some embodiments of the present disclosure. As shown in fig. 1, in some embodiments, the system 100 may include an environmental parameter acquisition unit 110, a determination unit 120, an eye state monitoring unit 130, and an adjustment unit 140. The environmental parameter acquisition unit 110 may acquire the environmental parameters of the environmental light around the display screen by a sensor mounted on the display screen in the vehicle. The determination unit 120 may determine whether the environmental parameter of the environmental light acquired by the environmental parameter acquisition unit 110 matches the display parameter of the corresponding display screen inside the vehicle. The eye state monitoring unit 130 may monitor the state of the eyes of the user through a camera mounted on a display screen of the vehicle interior. In the case where it is determined by the determination unit 120 that the environmental parameter of the environmental light acquired by the environmental parameter acquisition unit 110 does not match the display parameter of the display screen of the corresponding vehicle interior, the adjustment unit 140 may automatically adjust the display parameter of the display screen of the corresponding vehicle interior based on the environmental parameter of the environmental light acquired by the environmental parameter acquisition unit 110. In addition, the adjustment unit 140 may also automatically adjust display parameters of a display screen inside the vehicle based on the state of the eyes of the user monitored by the eye state monitoring unit 130.
The operation of the respective units as shown in fig. 1 will be described in further detail below.
Fig. 2 is an exemplary flowchart illustrating a method 200 for automatically adjusting display parameters of a display screen inside a vehicle according to some embodiments of the present disclosure.
As shown in fig. 2, the method 200 begins at step S210. At step S210, the environmental parameter acquisition unit 110 may acquire the environmental parameters of the environmental light around the display screen by a sensor mounted on the display screen of the vehicle interior. For example, the environmental parameter acquiring unit 110 may acquire the illumination intensity of the environmental light through a light sensor mounted on the display screen. In addition to this, the environmental parameter acquisition unit 110 may acquire more environmental parameters of the environmental light, such as color temperature of the environmental light, chromaticity of the environmental light, saturation of the environmental light, and the like, by other types of sensors such as a color temperature sensor and a chromaticity sensor. It should be understood that the types of sensors listed herein, as well as the environmental parameters of the ambient light, are exemplary only and not limiting.
Next, the method 200 proceeds to step S220. At step S220, the determination unit 120 may determine whether the environmental parameter of the environmental light acquired by the environmental parameter acquisition unit 110 matches the display parameter of the display screen of the corresponding vehicle interior. In some embodiments, for example, when the environmental parameter of the environmental light is illumination intensity of the environmental light, the display parameter of the corresponding display screen is brightness of the display screen. Similarly, when the environmental parameter of the environmental light is the color temperature/chromaticity of the environmental light, the display parameter of the corresponding display screen is the color temperature/chromaticity of the display screen.
Further, in some embodiments, the specific values of the environmental parameters of the environmental light acquired by the environmental parameter acquisition unit 110 may be divided into a plurality of levels according to actual demands, for example. In some embodiments, for example, the illumination intensity of ambient light has a value greater than 500lux of a first level, a value less than 500lux and greater than 100lux of a second level, and a value less than 100lux of a third level. It should be understood that the above-described multiple level partitioning is exemplary only and not limiting. For example, the value of the illumination intensity of the ambient light may be divided into fewer or more levels according to the actual requirements. Furthermore, the particular values described above are for illustrative purposes only and are not limiting.
In addition, in some embodiments, similarly to the above-described division of the values of the environmental parameters of the environmental light into the plurality of levels, the values of the display parameters of the display screen corresponding to the environmental parameters of the environmental light may also be divided into the plurality of levels, and the plurality of levels of the values of the environmental parameters of the environmental light and the plurality of levels of the values of the display parameters of the corresponding display screen are in one-to-one correspondence, so that the correspondence table of the environmental parameters of the environmental light and the display parameters of the corresponding display screen may be obtained. For example, a correspondence table of illumination intensity of ambient light and luminance of a display screen, a correspondence table of color temperature of ambient light and color temperature of a display screen, a correspondence table of chromaticity of ambient light and chromaticity of a display screen, and the like can be obtained.
In some embodiments, the determining unit 120 may determine whether the acquired illumination intensity of the ambient light matches the brightness of the display screen, for example, based on the above-described correspondence table of the illumination intensity of the ambient light and the brightness of the display screen. In addition to this, similarly, the determination unit 120 may determine whether or not the acquired color temperature of the ambient light matches the color temperature of the display screen based on the above-described correspondence table of the color temperature of the ambient light and the color temperature of the display screen. It should be understood that the above-described manner of determination by the determination unit 120 is merely exemplary and not limiting.
In the case where it is determined by the determination unit 120 that the environmental parameter (e.g., illumination intensity) of the environmental light acquired by the environmental parameter acquisition unit 110 does not match the display parameter (e.g., brightness) of the corresponding display screen of the vehicle interior (no in step S220), the method 200 proceeds to step S230. In the case where it is determined by the determination unit 120 that the environmental parameter (e.g., illumination intensity) of the environmental light acquired by the environmental parameter acquisition unit 110 matches the display parameter (e.g., brightness) of the display screen of the corresponding vehicle interior (yes in step S220), the method 200 proceeds to step S240.
At step S230, the adjustment unit 140 may automatically adjust the display parameters of the display screen of the corresponding vehicle interior based on the environmental parameters of the environmental light acquired by the environmental parameter acquisition unit 110. In some embodiments, for example, the adjusting unit 140 may automatically adjust the brightness of the display screen based on the acquired illumination intensity of the ambient light according to the above-mentioned correspondence table of the illumination intensity of the ambient light and the brightness of the display screen. Similarly, the adjusting unit 140 may also automatically adjust the color temperature of the display screen based on the acquired color temperature of the ambient light according to the above-described correspondence table of the color temperature of the ambient light and the color temperature of the display screen. It should be understood that the above-described adjustment by the adjustment unit 140 is merely exemplary and not limiting.
At step S240, the eye state monitoring unit 130 may monitor the state of the eyes of the user through a camera mounted on a display screen of the vehicle interior. For example, the eye state monitoring unit 130 may monitor the pupil diameter of the user, the eyeball movement state of the user, the eye opening amplitude of the user, and the like through a camera mounted on a display screen inside the vehicle. Then, the method 200 proceeds to step S250. At step S250, the adjustment unit 140 may automatically adjust display parameters of a display screen inside the vehicle based on the state of the eyes of the user monitored by the eye state monitoring unit 130 at step S240. The operations at step S240 and step S250 will be described in detail later with reference to fig. 3 and 4.
Through the above-mentioned method 200, the display parameters of the corresponding display screen may be automatically adjusted based on the environmental parameters of the ambient light around the display screen and the states of the eyes of the user, so that the brightness, color temperature, chromaticity, etc. of the display screen may be adjusted to a degree matching with the illumination intensity, color temperature, and chromaticity of the current ambient light, thereby avoiding the following situations: the user (e.g., viewer) cannot see the picture played by the display screen because the illumination intensity of the ambient light does not match the brightness of the display screen (e.g., the illumination intensity of the ambient light is too high and the brightness of the display screen is too low). Through the method 200 described above, the viewing experience of the user can be improved and a good viewing environment can be created.
In some embodiments, in the case where the value of the environmental parameter of the environmental light is divided into a plurality of levels as described above, if the frequency at which the value of the environmental parameter of the environmental light is switched between different levels of the plurality of levels within a certain period of time is greater than a preset frequency, the adjustment unit 140 may automatically adjust the display parameter of the display screen inside the corresponding vehicle without based on the environmental parameter of the environmental light acquired by the environmental parameter acquisition unit 110. In some embodiments, the adjustment unit 140 may also perform control to automatically raise the shade of the vehicle interior. For example, when the number of times of switching back and forth between the above-described first level and second level within, for example, 5 minutes, which is a value of the illumination intensity of the ambient light acquired by the ambient parameter acquisition unit 110, reaches, for example, 3 times or more, it may be determined that the illumination intensity of the ambient light around the display screen inside the vehicle is frequently changing at this time (for example, the vehicle may be traveling on a boulevard). In this case, if the display parameters (e.g., brightness) of the corresponding display screen are adjusted based on the environmental parameters (e.g., illumination intensity) of the ambient light as in the method 200, the display parameters (e.g., brightness) of the display screen may be caused to frequently change, instead causing the user to feel uncomfortable. Therefore, in order to avoid frequent changes in the display parameters of the display screen caused by the above-described situation, upon occurrence of the above-described situation, the adjustment unit 140 may automatically adjust the display parameters of the display screen of the corresponding vehicle interior, not based on the environmental parameters of the environmental light acquired by the environmental parameter acquisition unit 110. Furthermore, in some embodiments, the adjustment unit 140 may also perform control to automatically raise the shade of the vehicle interior, so that frequent changes in the value of the environmental parameter of the ambient light may be further avoided. In this way, a better viewing experience can be provided to the user and unnecessary impact on the user is reduced.
Next, the operations at step S240 and step S250 in the above-described method 200 will be described in detail with reference to fig. 3 and 4.
Fig. 3 is an exemplary flowchart illustrating a method 300 for automatically adjusting display parameters of a display screen of a vehicle interior according to further embodiments of the present disclosure.
As shown in fig. 3, the method 300 begins at step S310. At step S310, the eye state monitoring unit 130 may monitor the pupil diameter of the user in real time through a camera mounted on a display screen of the vehicle interior and store data on the pupil diameter of the user. For example, the eye state monitoring unit 130 may capture a face image of the user through a camera, then recognize a pupil portion in the face image according to a known image recognition method or the like and calculate the pupil diameter of the user based on a known algorithm. Since the present disclosure does not focus on a specific calculation method of the pupil diameter, redundant description is not made here.
Next, the method 300 proceeds to step S320. At step S320, the pupil diameter of the user at the current time monitored by the eye state monitoring unit 130 may be compared with the previously stored pupil diameter of the user at the previous time by a comparison unit not shown. In some embodiments, the eye state monitoring unit 130 may capture facial images of the user and calculate the pupil diameter of the corresponding user, for example, at certain time intervals (e.g., 5 seconds). Thus, the comparison unit may compare the pupil diameter of the user at the current moment with the pupil diameter of the user, for example, 5 seconds ago. In some embodiments, the comparison by the comparison unit may comprise comparing a magnitude relation between the pupil diameter of the user at the current time and the pupil diameter of the user at the previous time. In addition, the comparison by the comparison unit may further include calculating a difference between the pupil diameter of the user at the present time and the pupil diameter of the user at the previous time and comparing the calculated difference with a predetermined threshold value.
In some embodiments, the adjustment unit 140 may automatically adjust the brightness of the display screen inside the vehicle based on the comparison performed by the comparison unit at step S320. Next, how the adjustment unit 140 automatically adjusts the brightness of the display screen inside the vehicle based on the comparison performed by the comparison unit at step S320 will be described in detail.
In general, for example, the pupil diameter decreases as the illumination intensity of the ambient light increases, and increases as the illumination intensity of the ambient light decreases. Thus, in some embodiments, for example, at step S330, when the comparison by the comparison unit at step S320 indicates that the pupil diameter of the user at the current time is greater than the pupil diameter of the user at the previous time (yes in step S330), the method proceeds to step S340, otherwise the method 300 ends.
At step S340, when the comparison performed by the comparison unit at step S320 indicates that the difference between the pupil diameter of the user at the present time and the pupil diameter of the user at the previous time is greater than the preset first threshold (yes in step S340), the method proceeds to step S350, otherwise the method 300 ends. The fact that the pupil diameter of the user at the present moment is larger than the pupil diameter of the user at the previous moment and the difference between them is larger than the preset first threshold value indicates that the illumination intensity of the present ambient light is significantly reduced, resulting in a significant increase of the pupil diameter. Here, the first threshold value set in advance may be set according to actual conditions and may be, for example, about 1mm.
At step S350, as described above, since the illumination intensity of the current ambient light is significantly reduced, the brightness of the display screen inside the vehicle can be reduced by the adjustment unit 140.
Further, in some embodiments, for example, at step S360, when the comparison performed by the comparison unit at step S320 indicates that the pupil diameter of the user at the current time is smaller than the pupil diameter of the user at the previous time (yes in step S360), the method proceeds to step S370, otherwise the method 300 ends.
At step S370, when the comparison performed by the comparison unit at step S320 indicates that the difference between the pupil diameter of the user at the present time and the pupil diameter of the user at the previous time is greater than the preset second threshold (yes in step S370), the method proceeds to step S380, otherwise the method 300 ends. The fact that the pupil diameter of the user at the present moment is smaller than the pupil diameter of the user at the previous moment and the difference between them is larger than the preset second threshold value indicates that the illumination intensity of the present ambient light is significantly increased, thereby causing a significant reduction of the pupil diameter. Here, the second threshold value set in advance may be set according to actual conditions and may be the same as or different from the first threshold value.
At step S380, as described above, since the illumination intensity of the current ambient light is significantly increased, the brightness of the display screen inside the vehicle can be increased by the adjustment unit 140.
Through the method 300, the brightness of the display screen in the vehicle can be adaptively adjusted based on the state of the eyes of the user, specifically, the pupil diameter of the user, so that a better viewing experience can be brought to the user, and discomfort caused by the brightness of the display screen which is too bright or too dark to the eyes of the user can be avoided.
Fig. 4 is an exemplary flowchart illustrating a method 400 for automatically adjusting display parameters of a display screen of a vehicle interior according to further embodiments of the present disclosure.
As shown in fig. 4, the method 400 begins at step S410. At step S410, the eye state monitoring unit 130 may monitor the eyeball movement state of the user in real time through a camera mounted on a display screen inside the vehicle. For example, the eye state monitoring unit 130 may capture a face image of a user by a camera, and then recognize an eyeball portion in the face image and determine an eyeball movement state such as a movement direction of the eyeball, a rotation angle of the eyeball, or the like according to a known image recognition method or the like. Since the present disclosure does not focus on a specific method of determining the state of eye movement, redundant description is not made here.
Next, the method 400 proceeds to step S420. At step S420, the above-described determination unit 120 or other unit may determine whether the user views the display screen inside the vehicle based on the state of eye movement of the user monitored by the eye state monitoring unit 130 at step S410. For example, when the eye state monitoring unit 130 monitors that the rotation angle of the eyeball of the user is out of the range in which the display screen inside the vehicle can be viewed, the determining unit 120 may determine that the display screen is not being viewed by the user at this time (for example, the user may be looking out of the window at this time or the user may be looking down at the mobile phone). Here, a specific value of the rotation angle of the eyeball of the user that is out of the range in which the display screen inside the vehicle can be viewed may be predetermined according to the actual situation. It should be appreciated that the above-described manner of determining whether a user views a display screen inside a vehicle is merely exemplary and not limiting.
Next, the method 400 proceeds to step S430. At step S430, in the case where it is determined by the determining unit 120 that the user does not view the display screen inside the vehicle for a certain period of time, the adjusting unit 140 may automatically decrease the brightness of the display screen inside the vehicle and/or turn off the display screen inside the vehicle. For example, when the determining unit 120 determines that the user does not view the display screen of the vehicle interior within, for example, 5 minutes, the adjusting unit 140 may decrease the brightness of the display screen of the vehicle interior to save power. In some embodiments, the adjustment unit 140 may also pause the playback of the display screen inside the vehicle and/or turn off the display screen inside the vehicle to avoid disturbing the user.
By the above-described method 400, the brightness of the display screen inside the vehicle can be adaptively adjusted based on the state of the eyes of the user, specifically, the state of eye movement of the user, so that the brightness of the display screen can be automatically reduced when the user is not viewing the display screen, whereby power can be saved and unnecessary interference to the user can also be reduced.
In addition to the methods 300 and 400 described above, methods according to the present disclosure may further include monitoring the eye-open amplitude of the user in real-time by the eye-state monitoring unit 130. For example, similar to the pupil diameter of the monitoring user in the method 300 and the eye movement state of the monitoring user in the method 400, the eye state monitoring unit 130 may capture a facial image of the user through a camera, and then identify eye portions in the facial image and determine the eye opening amplitude of the eyes according to a known image identification method or the like. Since the present disclosure does not focus on a specific method of determining the eye-opening amplitude of the eyes, redundant description is not made here.
In some embodiments, the adjustment unit 140 may automatically decrease the brightness of the display screen inside the vehicle when the magnitude of the opening eyes of the user monitored by the eye state monitoring unit 130 is less than a preset magnitude. For example, when the eye-open amplitude of the user monitored by the eye-state monitoring unit 130 is less than half of the normal eye-open amplitude, it may be determined that the eyes of the user may be in a tired state or an eye-closed state at this time. In this case, the adjustment unit 140 may automatically reduce the brightness of the display screen inside the vehicle, pause the playback of the display screen inside the vehicle, and/or turn off the display screen inside the vehicle to reduce the irritation to the eyes of the user.
In addition, the method according to the present disclosure may further include monitoring whether a person is present in front of the display screen of the vehicle interior by a camera mounted on the display screen of the vehicle interior. For example, an image in front of a display screen of a vehicle interior may be captured by a camera mounted on the display screen of the vehicle interior, and whether a person is present in the captured image may be determined by, for example, a known image recognition method. In some embodiments, in the absence of a person in the captured image-i.e., in the event that no person is detected in front of the display screen of the vehicle interior-the adjustment unit 140 may automatically pause the playback of the display screen of the vehicle interior and/or turn off the display screen of the vehicle interior in order to save power.
Further, according to the method of the present disclosure, road information may be acquired through a car navigation system inside the vehicle. In some embodiments, the adjustment unit 140 may reduce the brightness of the display screen inside the vehicle in advance when the acquired road information indicates that the vehicle will travel through the tunnel. By this means, it is possible to judge in advance whether the vehicle will travel through the tunnel based on the road information. When the acquired road information indicates that the vehicle is going through the tunnel, for example, the brightness of the display screen inside the vehicle may be reduced in advance by the adjustment unit 140, thereby providing a better viewing experience for the user.
As described above, the present disclosure provides systems and methods for automatically adjusting display parameters of a display screen inside a vehicle. According to the method disclosed by the invention, the display parameters of the corresponding display screen can be automatically adjusted based on the environment parameters of the environment light around the display screen and the states of the eyes of the user, so that the viewing experience of the user is improved, and discomfort of the user caused by mismatch between the environment parameters of the environment light and the display parameters of the display screen can be avoided. In addition, according to the method disclosed by the invention, the brightness of the display screen in the vehicle can be adaptively adjusted based on the state of the eyes of the user, so that better watching experience can be brought to the user, and discomfort caused by the brightness of the display screen which is too bright or too dark to the eyes of the user can be avoided. In addition, adaptively adjusting the brightness of the display screen inside the vehicle based on the state of the user's eyes may also save power and reduce unnecessary interference and irritation to the user's eyes. In addition, according to the method disclosed by the invention, frequent changes of the display parameters of the display screen caused by frequent changes of the numerical values of the environmental parameters of the environmental light can be avoided, so that better viewing experience can be provided for the user, and unnecessary influence on the user is reduced.
