For a more complete understanding of the nature and the technical content of the embodiments of the present application, reference should be made to the following detailed description of embodiments of the application, taken in conjunction with the accompanying drawings, which are meant to be illustrative only and not limiting of the embodiments of the application.

It is to be understood that the "first\second\third" distinguishing objects may be interchanged where appropriate such that embodiments of the application described herein may be practiced in sequences other than those illustrated or described herein.

In an embodiment of the present application, the technical solution of the present application may be implemented on any electronic device, such as a tablet computer, a desktop computer, a notebook computer, a server, a public information inquiry station, a mobile phone, etc.

Fig. 1 is a flow chart of a display control method according to an embodiment of the present application. As shown in fig. 1, the method may include steps 101 to 103:

step 101, obtaining a first parameter and a second parameter.

In the embodiment of the present application, the current scene at least includes a target object and a target device, where the target device is used to display an image content to the target object, and accordingly, in the process that the target object receives the image content, due to the influence of illumination, the target device may have a reflection phenomenon in an area where the image content is displayed, so that the target object cannot receive the original image content.

In some embodiments, the first parameter characterizes position information of the target object. The target object is an object capable of receiving the image content displayed by the target device. By way of example, the target object may be, but is not limited to, a person, a video camera, a still camera, and the like. The above-mentioned position information may be a position coordinate of the target object in the world coordinate system, specifically, the first parameter is a position coordinate of the image capturing portion of the target object in the world coordinate system, for example, in the case that the target object is a person, the first parameter is a position coordinate of a person's eye in the world coordinate system; in the case where the target object is a camera, the first parameter is a coordinate position of a lens of the camera in a world coordinate system.

In some embodiments, the first parameter may be obtained by an internal sensor deployed in the target object or target device, or may be obtained by an external sensor deployed outside the target object. In an exemplary case where the target object is a person, the first parameter may be acquired through a wearable sensor disposed on the head, or may be acquired through an eye tracking device disposed in the current scene, and the first parameter may be acquired based on an image recognition and tracking algorithm. The eye tracking device may be a third party device or a sensor device in the target device.

In some embodiments, the second parameter characterizes a relative pose of the target device, such as an angle, orientation, etc. of the target device. The target device is a device capable of displaying image content. By way of example, the target device may be, but is not limited to, a tablet, notebook, cell phone, etc. The second parameter may be a relative pose between screens of the target device in the world coordinate system or a relative pose between a screen and a placement plane, for example, when the target device includes one screen, the second parameter may be a relative pose between a plurality of areas between screens in the world coordinate system or a relative pose between one screen and a desktop on which the screen is placed; when the target device comprises at least two screens, the second parameter is the relative pose between the at least two screens in the world coordinate system.

In some embodiments, the second parameter may be obtained by internal sensors within the target device, and the relative pose of the target device may also be determined by detecting changes in the angle of portions of the target device as they deform. The second parameter may be obtained by detecting the pose of the target device when the target device includes one screen by the gravity sensor, or may be obtained by detecting the bending angle of the bendable portion of the screen to determine the relative pose of the target device, and may be obtained by detecting the rotation angle of the connecting shaft of the two screens when the target device includes two screens.

Step 102, determining a target area based on the first parameter and the second parameter.

The target area is an area which generates visual influence on the target object, and belongs to a screen area of the target device.

In some embodiments, the visual effect on the target object refers to a negative effect that interferes with the normal viewing behavior of the user, for example, the visual effect may refer to a visual effect that is generated on the target object after the projection of strong light or other images and the content to be observed by the target object are overlapped in the target area, and for example, the target object needs to observe the movie being played on the screen, and at this time, the light emitted by the other light sources reflects light, and is overlapped with the movie being played, so that the target object cannot observe the original content of the movie well.

In some embodiments, the area that affects the vision of the target object, i.e. the target area, refers to the area that may directly or indirectly affect the vision of the target object, for example, the area a of the screen a generates the light reflection on the area B of the screen B, where the area B directly affects the vision of the user, and the area a indirectly affects the vision of the user, where the area a and/or the area B may be regarded as the target area, and the number of target areas is not limited, where the area a and the area B are merely exemplary illustrations of how to determine the target area, and in the foregoing illustrations, all areas of the screen a and the screen B are screen areas of the target device, and the foregoing A, B screen and the area a and the area B are merely for illustrating the area and the screen area that affect the vision of the target, and are not limited to the screen or the number of the areas.

In some embodiments, the target area may be determined by directly calculating based on the first parameter and the second parameter by an internal system of the target device, or by deploying a sensor for the target object and analyzing the acquired visual image, and determining the target area in combination with the first parameter and the second parameter, where, by way of example, the target device may determine, based on the first parameter and the second parameter, a light path from a light ray emitted by the target device that reaches the target object after being reflected, and further determine the target area, or by deploying a sensor for the target object, acquiring a real-time image, identifying a reflective area in the image, and determining, based on the first parameter and the second parameter, a target area on a screen area in the world coordinate system.

Step 103, in response to the instruction for visual impact, performing brightness compensation on the target area.

In some embodiments, the instruction is automatically issued by the system, which may be an instruction to adjust the target area screen, after the system has performed steps 101-102, to determine the target area and how to adjust the target area to eliminate the visual impact of the target area on the target object.

In some embodiments, the brightness compensation of the target area may be characterized by adjusting the brightness of the target area, specifically, may be adjusting the brightness of the target area entirely or adjusting the brightness of a part of the pixels in the target area individually, and any control method capable of adjusting the brightness of the screen may be used in the embodiments of the present application, which is not limited herein specifically.

Through the above, in the use of electronic equipment, because other screens or light sources emit light to form reflection on the screen, normal use of the screen by a user is affected, in this case, in order to reduce the reflection, if the light is no longer reflected into human eyes through the screen only by adjusting the angle of the screen, the effect achieved by this method is not ideal in the case of a large reflection area or more light sources. Therefore, the embodiment of the application does not adjust the screen angle, but determines the target area needing to be subjected to brightness compensation based on the position information of the target object and the pose information of the target device through steps 101-103, and performs brightness compensation on the target area to weaken or eliminate bad visual influence of glare on a user, thereby improving the viewing experience of the user, and simultaneously, the steps can be repeatedly executed along with the change of the first parameter and the second parameter so as to correct the position and the range of the target area, thereby ensuring that the user can always obtain a good compensation effect in the use process.

It should be noted that, the target area determined based on the first parameter and the second parameter is an area capable of generating a visual effect on the target object, and the subsequent adjustment of brightness is performed on the target area, it should be understood that as the target object is continuously moving, the first parameter is correspondingly changed, and the corresponding target area is correspondingly changed, so that it is necessary to determine the target area based on the first parameter and the second parameter, if brightness compensation is performed on the original target area when the first parameter is changed, a good compensation effect cannot be obtained and the use experience of the user is further reduced;

the glare and the reflection are the same in meaning hereinafter, and refer to the physical phenomenon generated by the light after being reflected by the screen, and in the following embodiments, the two can be replaced with each other, which is only different in that the glare mainly shows the subjective feeling of the influence of the reflection on human eyes, and the reflection objectively describes the physical phenomenon of light emission only from the perspective of equipment.

In the embodiment of the application, the target device in the current scene at least comprises two screens, when the target object looks at one of the screens, correspondingly, in the process that the target object receives the content displayed on the looked-at screen, because the other screens send out the influence of light rays, the target device may have a glare phenomenon in the area where the content is displayed, and the target object cannot watch the original display content.

In the above scenario, the second parameter obtained in step 101 of fig. 1 may be updated as: obtaining the second parameter if the target device comprises at least two screens; the second parameter characterizes a first angle between the at least two screens.

In some embodiments, the at least two screens of the target device are two screens independent of each other, and may display content independently, and control a switch independently, and illustratively, the screen EFAB and the screen ABCD in fig. 2 are two screens independent of each other of the device.

In some embodiments, the included angle between at least two screens may be obtained by detecting the rotation angle of the connecting shaft between the screens, or may be obtained by determining a plane equation of each screen in the world coordinate system to calculate the included angle between the screens, and taking the notebook computer as an example, when the notebook computer is in a buckled state, the rotation shaft between the two screens does not rotate at this time, which may be regarded as 0 ° between the two screens, and when the notebook computer is unfolded, the rotation shaft rotates, which may be regarded as the included angle between the two screens at this time; the coordinate system may be established by taking a certain screen plane of the notebook computer as a reference plane and the center of the screen as an origin, taking the size of the notebook computer as a coordinate value to be substituted into the coordinate system to calculate a plane equation of each screen, solving the angles between the planes, taking the angles obtained as the angles between the screens, and the second parameter obtained in the embodiment may be applied to step 102 to determine the target area based on the first parameter and the second parameter.

In the embodiment of the application, the target device in the current scene comprises a screen, the screen can be a foldable screen, when a user bends the screen, the screen is divided into two areas along the bending position, when the user focuses on the content of one area, the light rays emitted by the other screen area can generate glare in the area of the screen focused on by the user, and the viewing of the user is influenced.

In some embodiments, the target device in the above scenario that includes one screen is a foldable device. The screen of the target device may be deformed by bending or other means to form two display areas. By way of example, the target device may be a foldable cellular phone, a foldable tablet computer, or the like. The first area and the second area are two display areas formed by taking a bending area as a boundary when the screen of the foldable equipment is bent, and the second included angle is an included angle between the two display areas. In the case of a foldable mobile phone of the target device, the bending operation is performed on the screen of the mobile phone, and at this time, the screen is deformed due to bending, and two display areas are formed by taking the crease as a boundary, and the two display areas are a first area and a second area, and an included angle between the two areas is a second included angle.

In some embodiments, the second parameter may be obtained by detecting the relative pose information between the two regions through a gyroscope built in the target device, or may be directly obtained by detecting the bending angle of the target device. For example, when the target device is a foldable mobile phone, a plurality of gyroscopes may be set in the mobile phone to detect pose information of different areas to obtain the second parameter, or the second parameter may be directly determined by directly detecting a bending angle of a bendable portion of the mobile phone, and the second parameter obtained in this embodiment may be applied to step 102 to determine the target area based on the first parameter and the second parameter.

In the embodiment of the application, the target device in the current scene comprises a screen, and the screen can be an integral screen which is not foldable, and in the process of looking at the content played by the screen, the user cannot see the content originally played by the screen because the illumination generated by the light source outside the target device is reflected by the screen and overlapped with the content originally played by the screen.

In the above scenario, the target device includes a screen that is not deformable, i.e., the screen is entirely one area and is not deformable by bending or the like to form a plurality of display areas. By way of example, the target device may be a display, notebook, mobile phone, etc., which is not flexible in the screen. The target plane is a platform or plane on which the target device is placed. By way of example, the target plane may be a desktop surface on which a display is placed, a podium on which a notebook computer is placed, etc., wherein a horizontal plane may be taken as the target plane if the target device is not placed on any plane or table top. The third angle may be an angle between a screen of the target device and the target plane, and specifically, the second parameter is an angle between a plane of the screen of the target device and the target plane, for example, in a case where the target device is a mobile phone, the second parameter is an angle formed by a plane of the phone screen and a horizontal plane; in the case that the target object is a notebook computer placed on a desktop, the second parameter is an included angle formed between a screen of the notebook computer and the desktop.

In some embodiments, the second parameter may be obtained by obtaining the relative pose of the horizontal plane with the sensor inside the device using the horizontal plane directly as the target plane. For example, when the notebook computer is placed on the desktop, the desktop may be regarded as horizontal, and at this time, the second parameter, which is the angle between the screen of the notebook computer and the desktop, may be obtained only by obtaining the angle between the screen and the horizontal plane through the sensor built in the notebook computer, and the second parameter obtained in this embodiment may be applied to step 102, and the target area is determined based on the first parameter and the second parameter.

In some embodiments, after obtaining the second parameter, the method further comprises: obtaining a third parameter; the third parameter characterizes a position of a target light source, which is a light source that can have a visual impact on the target object.

In some embodiments, the current scene includes a target object, a target device, and a target light source, the target object and the target device representing the same objects and devices as in the embodiments described above.

In the above scenario, the third parameter characterizes the position information of the target light source. The target light source is a light source object except for the target device, specifically, the target light source can be any light-emitting object, such as an incandescent lamp, a flashlight, a sun and the like, and can be an object which does not emit light but can reflect light, such as a plane mirror, glass and the like. Wherein the position may be the position coordinate of the target light source in the world coordinate system, specifically, the third parameter is the position coordinate of the light emitting or reflecting portion of the target light source in the world coordinate system, for example, when the target light source is an incandescent lamp, the third parameter is the position coordinate of the incandescent lamp in the world coordinate system; when the target object is a plane mirror, the third parameter is the position coordinate of the part of the plane mirror, which reflects light and can reach the target object through the reflection of the screen, in the world coordinate system.

In some embodiments, the third parameter may be obtained by identifying the light source image by using an external photographing device of the target device, or may be determined by infrared scanning. In an exemplary case where the target light source is an incandescent lamp, the light source image may be acquired through a photographing device disposed outside the target device to identify the light source image to acquire a third parameter, or the distance and angle between the incandescent lamp and the target device may be acquired through infrared scanning to acquire the third parameter, where the third parameter acquired in this embodiment may be applied to step 102, and the target area is determined based on the first parameter, the second parameter and the third parameter.

In some embodiments, the determining the target area based on the first parameter and the second parameter may be further implemented by:

In some embodiments, if the target device includes a screen, determining the target area based on the first parameter, the second parameter, and the third parameter may further be implemented by:

the target object is regarded as a luminous light source, and the directions of all reflected light rays of the light rays emitted by the target object after being reflected by the screen are determined based on the first parameter and the second parameter; based on the third parameter and the direction of the reflected light, a set of reflected light passing through the target light source in the reflected light is determined, and a set of reflection points corresponding to the reflected light is determined as a target area, where the target area determined in this embodiment may be the area where brightness compensation is performed in step 103.

In the embodiment of the application, the target device in the current scene comprises at least two screens, wherein light rays emitted by one screen can form glare on the other screen, and the glare can have bad visual influence on the target object when the target object views any one of the screens.

In some embodiments, in the above scenario, the determining the target area based on the first parameter and the second parameter, and performing brightness compensation on the target area may be implemented by the following method: determining a target area comprising a light reflecting area based on the first parameter and the second parameter, and adjusting the light emitting brightness of the light reflecting area; determining a target area comprising a light emitting area based on the first parameter and the second parameter, and adjusting the light emitting brightness of the light emitting area; and determining a target area comprising a light emitting area and a light reflecting area based on the first parameter and the second parameter, and cooperatively adjusting the light emitting brightness of the light emitting area and the light reflecting area.

And adjusting the light-emitting brightness of the light-reflecting area according to the target area determined based on the first parameter and the second parameter. The embodiment of the application can adjust the overall luminous brightness of the screen where the light reflecting area is located, and can also adjust the luminous brightness of the area of the screen where the light reflecting area is located.

In the process of adjusting the overall brightness of the screen where the light reflecting area is located, the screen comprises the light reflecting area, so that the light emitting brightness of the light reflecting area is correspondingly adjusted after the overall brightness of the screen is adjusted.

In the process of adjusting the brightness of the area of the screen where the light reflecting area is located, the area needing to be adjusted in brightness, namely the light reflecting area, can be determined first. The light reflecting area is a screen area which is observed by a target object and generates light reflection on a screen, and the position of the light reflecting area is not fixed and can be changed along with the change of the first parameter and the second parameter, but does not exceed the screen range of target equipment. For example, when the target object observes the second screen, the target object may observe a glare or projection formed on the second screen by the content played on the first screen, and the area where the glare or projection is located is a reflective area, and along with the change of the position of the target object and the included angle between the first screen and the second screen, the position of the reflective area on the second screen also changes correspondingly. The light-emitting brightness of the light-reflecting area is the light-emitting brightness of the screen of the light-reflecting area, and specifically, the light-emitting brightness is the sum of the brightness of all pixel points of the screen in the light-reflecting area. For example, the screen of the reflective area on the second screen will emit light, and the sum of the luminous intensities of the pixels of the screen in the area is the luminous intensity of the reflective area.

In some embodiments, an observation light path of the target object may be established based on the first parameter and the second parameter, and it is determined that reflection areas on the second screen corresponding to all light paths emitted by the target object and capable of reaching the first screen through reflection by the second screen are light reflection areas. For example, when the target object is a person, the human eye can be regarded as the light source to emit light, the direction of the reflected light of the light emitted by the human eye after being reflected by the second screen is obtained based on the first parameter and the second parameter, and the reflection area formed on the second screen by the light which can reach the first screen by the reflected light is determined as the reflection area.

In some embodiments, the brightness of the reflective area may be adjusted by integrally adjusting the brightness of the screen of the reflective area, and the brightness of a portion of the pixels in the screen of the reflective area may be adjusted by adjusting the brightness of the portion of the pixels in the screen of the reflective area.

And adjusting the light-emitting brightness of the light-emitting region with respect to the above-described process of determining the target region including the light-emitting region based on the first parameter and the second parameter. The embodiment of the application can adjust the overall luminous brightness of the screen where the luminous area is located, and can also adjust the luminous brightness of the area of the screen where the luminous area is located.

In the process of adjusting the overall light-emitting brightness of the screen where the light-emitting area is located, since the screen includes the light-emitting area, after the overall light-emitting brightness of the screen is adjusted, the light-emitting brightness of the light-emitting area is correspondingly adjusted.

In the process of adjusting the light-emitting brightness of the area of the screen where the light-emitting area is located, the area where the brightness needs to be adjusted, that is, the light-emitting area, may be determined first. The light-emitting area is an area where light emitted from the screen can reach the target object through reflection of the light-reflecting area, wherein the light-emitting area and the light-reflecting area are positioned on different screens. For example, there is a region a on the first screen, and the light emitted by the region a may reach the target object by being reflected by the second screen, so that the region a on the first screen is the light emitting region.

In some embodiments, the light emitting region may be determined based on the same method as in the above embodiments. The light emitted by the target object is determined to reach the area formed by the first screen after being reflected by the second screen, and the brightness of the light-emitting area can be adjusted based on the method for adjusting the brightness of the light-reflecting area in the above embodiment.

And a process of adjusting the light emission brightness of the light reflection area and the light reflection area in cooperation with respect to the above-described target area including the light emission area and the light reflection area determined based on the first parameter and the second parameter. The embodiment of the application can adjust the whole brightness of the reflecting area and the screen where the reflecting area is positioned, and also can adjust the brightness of the reflecting area and the area of the screen where the luminous area is positioned.

In the process of adjusting the overall brightness of the screen where the light reflecting area and the light emitting area are located, the screen respectively comprises the light reflecting area and the light emitting area, so that after the overall brightness of the screen is adjusted, the light emitting brightness of the light reflecting area and the light emitting area is correspondingly adjusted.

In the process of adjusting the brightness of the areas of the screen where the light reflecting area and the light emitting area are located, the area where the brightness needs to be adjusted, namely the light reflecting area and the light emitting area, can be determined first.

In some embodiments, the collaborative adjustment characterization may adjust the brightness of the light emitting area and the light reflecting area at the same time, or may sequentially adjust the brightness of the light emitting area and the light reflecting area, the order and the number of adjustment are not limited, and the adjustment method for the light emitting brightness of each area may be the same as the adjustment method in the above embodiments, that is, the adjusted screen may overcome the visual influence of the glare on the target object.

In some embodiments, adjusting the light emission luminance of the region includes: and determining the reflection brightness of the reflection area, and adjusting the luminous brightness of the reflection area and/or adjusting the luminous brightness of the luminous area according to the reflection brightness.

In some embodiments, the retroreflective brightness of the retroreflective regions characterizes the brightness of the retroreflective formed by the light emitted from the retroreflective regions after being reflected by the retroreflective regions. The light emitted by the light emitting area of the first screen is emitted to the second screen through the first screen panel, and then is reflected by the second screen to finally reach the target object, so that the sum of the brightness of the light reaching the target object is the reflection brightness.

In some embodiments, the brightness of the light-emitting area can be adjusted to reduce the brightness of the light-reflecting area to a negligible extent, the brightness of the light-reflecting area after the light-reflecting brightness is overlapped with the brightness of the light-reflecting area is the same as the brightness of the light-reflecting area before the light-reflecting area is adjusted, and the brightness of the light-reflecting area and the brightness of the light-emitting area can be simultaneously adjusted to achieve the effect of overcoming the visual influence caused by light reflection. For the area with brightness adjustment, the brightness of the area is different from the brightness of other areas on the same screen, because the brightness of the same screen defaults to be the same, so that obvious glare can be generated, if the brightness of a certain area on the screen is lower, obvious visual influence can not be generated after the area is overlapped with the reflective brightness, and adjustment is not needed. Illustratively, after adjusting the brightness of the light-emitting region on the first screen, the brightness of the light-emitting region is different from the brightness of the other regions on the first screen.

In some embodiments, the determining a target region including a light emitting region and a light reflecting region based on the first parameter and the second parameter includes: constructing all observation light paths based on the first parameter and the second parameter; the observation light path starts from the target object, reflects through a reflection point of the second screen and falls on a luminous point of the first screen; the at least two screens include at least the first screen and a second screen; determining a screen area where each light emitting point is located as the light emitting area, and determining a screen area where each light reflecting point is located as the light reflecting area; and determining the light reflecting area and the light emitting area as the target area.

The observation light path characterization uses a target object as a light source, the light path formed by light rays emitted by the target object is characterized in that the reflection point is a contact point between the observation light path and the second screen when the observation light path is reflected by the second screen, and the light emitting point is an intersection point formed by the observation light path and the first screen after the observation light path is reflected by the second screen.

Wherein, the determination target area of the constructed observation optical path can be determined by taking the center of the second screen (ABCD) as an origin O, taking the axis parallel to the horizontal direction of the second screen as an X-axis, taking the axis parallel to the vertical direction of the second screen as a through-point O, taking the axis perpendicular to the second screen as a Z-axis, establishing a space rectangular coordinate system, and setting four vertexes of the second screen as a (X _A ,y _A ,z _A ),B(x _B ,y _B ,z _B ),C(x _C ,y _C ,z _C ),D(x _D ,y _D ,z _D ) The four vertices of the first screen are a (x _A ,y _A ,z _A ),B(x _B ,y _B ,z _B ),E(x _E ,y _E ,z _E ),F(x _F ,y _F ,z _F ) The included angle between the first screen and the second screen is theta. The position coordinates of the target object are I (x _I ,y _I ,z _I ). I.e. x _A ＝x _D ＝x _F ＝x ₀ ,x _B ＝x _C ＝x _E ＝-x ₀ ,y _A ＝y _B ＝y ₀ ,y _C ＝y _D ＝-y ₀ ,z _A ＝z _B ＝z _C ＝z _D =0. Is easy to find by the included angle theta, z _E ＝z _F ＝2y ₀ sinθ，y _E ＝y _F ＝2y ₀ cos θ. Wherein the equation of the second screen is z=0 (-x) ₀ ≤x≤x ₀ ,-y ₀ ≤y≤y ₀ ). The normal vector of the plane in which it is located is: n= (0, 1), the plane equation of the first screen (AFEB) is a ₀ x+B ₀ y+C ₀ z+D ₀ ＝0(-x ₀ ≤x≤x ₀ )。

Wherein, parameter A in the equation of the first screen ₀ 、B ₀ 、C ₀ 、D ₀ Can be derived from equation (1).

As the preparation calculation for establishing the observation optical path above, calculation will be performed taking as an example the establishment of one observation optical path.

Let the coordinates of any point G on the second screen be (x ', y', 0), point G can be regarded as a reflecting point on the second screen, the light should be emitted from a point H on the first screen, point H can be regarded as a reflecting point on the first screen, the light emitted from point H enters human eye I after being reflected by point G on the second screen, and since the light path is reversible, the human eye can be regarded as a reflecting point to establish an observation light path, namely, the light is regarded as being emitted from point I, and the equation of incident light IG is shown in formula (2):

the incident ray direction vector is shown in formula (3):

L＝(x′-x _I ,y′-y _I ,-z _I )x′∈[-x ₀ ,x ₀ ],y′∈[-y ₀ ,y ₀ ]formula (3);

the direction vector of the corresponding reflected light ray GH is shown in formula (4):

the equation for reflected ray GH is shown in equation (5):

At this time, the observation light path is established, the complete observation light path is IG-GH, and the light is emitted by the point I and reflected by the point G to reach the point H.

If the reflected light beam has an intersection point H with the first screen, the following formula (6) is solved, that is, the reflection will occur at the position G, and the reflection point corresponding to the point H is the point G:

expanding x' in the above formula (6) to [ -x) ₀ ,x ₀ ]Y' extends to [ -y ₀ ,y ₀ ]The method for determining the observation light path determines the observation light path formed by all the light rays emitted by the point I and directed to the second screen, so that the area formed by the intersection point of the observation light path and the first screen can be obtained, the area is determined as a light emitting area, and the corresponding area formed by the light reflecting point on the second screen is a light reflecting area.

In the embodiment of the application, the target device in the current scene comprises two screens, and when the target object looks at one of the screens, the light rays emitted by the other screen form reflection, so that adverse visual influence is generated on the target object.

In some embodiments, the co-adjusting the light emitting region and the light reflecting region comprises: and if the focus of the target object is positioned on the second screen, adjusting the luminous brightness of the luminous area, and if the target condition is not met, adjusting the luminous brightness of the light reflecting area.

In some embodiments, the focus of the target object characterizes the location of interest of the target object. For example, if the target object is a person, if the person looks at the second screen at this time, the focal point of the person's gaze is located on the second screen at this time, and if the target object is a camera, if the camera needs to capture the content of the second screen, the focal point of the camera is located on the second screen at this time.

In some embodiments, the target condition characterization may overcome the visual impact of light reflection. For example, if the target object still observes that there is reflection on the second screen after adjusting the brightness of the light emitting area on the first screen, the target condition is not satisfied at this time, and if the target object does not observe that there is reflection on the second screen, the target condition is satisfied at this time, that is, the brightness compensation of the light emitting area is insufficient to eliminate the visual influence on the user.

In some embodiments, the focal position of the target object may be determined by a tracking device built in the target device, and after determining that the focal point of the target object is located on the second screen, the light-emitting brightness of the light-emitting area on the first screen may be adjusted, specifically, the light-emitting brightness of the entire light-emitting area may be adjusted, or the brightness of a partial area within the light-emitting area may be adjusted.

In some embodiments, the value of the reflection brightness corresponding to the adjusted light emitting area may be calculated by the internal system of the target device, so as to determine whether the reflection brightness may have a visual effect on the target object, so as to determine whether the target condition is met, or whether the light currently reaching the target object includes reflection that affects the visual effect of the target object, so as to determine whether the target condition is met.

In some embodiments, when the target condition is not satisfied, the light-emitting brightness of the light-reflecting area is adjusted, and the adjustment method may be the same as the above-described method of adjusting the light-emitting brightness of the light-emitting area.

In some embodiments, the adjusting the light emitting brightness of the light emitting region includes: obtaining an adjustment coefficient, and adjusting the luminous brightness of the luminous area based on the adjustment coefficient; the adjusting the light-emitting brightness of the light-reflecting area comprises the following steps: obtaining a fourth parameter and a fifth parameter; the fourth parameter characterizes the transmissivity of the first screen and the fifth parameter characterizes the reflectivity of the second screen; determining the reflection brightness of the reflection area based on the fourth parameter, the fifth parameter and the brightness of the brightness-adjusted light-emitting area; the reflection brightness represents the brightness of reflection formed by the light-emitting area in the reflection area after adjustment; and reducing the light-emitting brightness of the light-reflecting area by units of the light-reflecting brightness.

In some embodiments, the light-emitting brightness of the region may be represented by a brightness value of each pixel, and the adjustment coefficient characterizes an operation parameter when adjusting each brightness value in the region. For example, the brightness value of all pixels in the current light emitting area is 100, and the brightness is required to be adjusted to be 80% of the current brightness based on the adjustment coefficient, the adjustment coefficient is 0.8, the brightness value of the adjusted pixels is 100×0.8=80, and due to factory setting of the screen, the adjustment coefficient has a maximum value and a minimum value, that is, the brightness of the screen has an upper limit and a lower limit when the screen is turned on.

In some embodiments, the transmittance is indicative of a ratio of an amount of light transmitted through the object to an amount of incident light in the incident light. Illustratively, there is a transparent cover on the screen, assuming that 90% of the light emitted by the pixel points is refracted through the transparent cover, and the remaining 10% of the light is reflected by the cover without passing through the cover, the transmittance of the transparent cover is 90%. The reflectivity is expressed as the ratio of the amount of light reflected by the surface of the object to the amount of light transmitted through the object, and the transparent cover plate is taken as an example, and assuming that 90% of the light emitted by the pixel points is reflected, the remaining 10% of the light passes through the cover plate, i.e. the reflectivity of the transparent cover plate is 90%, and the difference between the light transmittance and the reflectivity may be caused by the difference of the screen cover plate, the coating and the angle.

In some embodiments, the light reflection brightness of the light reflection area can be determined by setting the light emission point a on the first screen after the brightness is adjusted _i Brightness isThe first screen has light transmittance p (alpha), the second screen has reflectivity r (alpha), and the luminous point a _i Corresponding to the reflective point a 'on the second screen' _i Is +.> Further, the reflection point a 'is formed' _i Is reduced by->The corresponding numerical value can lead the sum of the reflection brightness and the luminous brightness of the reflection point to be the same as the reflection brightness before adjustment, and the reflection brightness of the reflection point to be described is +.>The light emission luminance is smaller than that of the reflection point before adjustment.

In some embodiments, adjusting the area light emission luminance includes: determining different color channels corresponding to each emitted ray; one area corresponds to a plurality of emitted light rays, and the sum of the luminous brightness corresponding to each emitted light ray is the regional luminous brightness; and adjusting the channel brightness of the channels with different colors to adjust the luminous brightness corresponding to the emitted light.

In some embodiments, a pixel includes three different color channels of RGB, a single pixel emits a light ray of a mixed color of three channels of RGB, a plurality of pixels are provided in a region, that is, each pixel emits a light ray, the sum of brightness of all pixels in the region is the brightness of the light ray in the region, the brightness of each pixel can be changed by adjusting the brightness of each channel of each pixel, and brightness difference exists between the combined different color channels and the combined light ray before combining, so that the adjustment accuracy can be improved by adjusting the brightness of the single color channel.

In some embodiments, the above-mentioned adjustment of the area light-emitting brightness may be achieved by the following method:
