Description

Technical Field

[0001] The present disclosure relates to the field of 3D display technologies, and in particular, to a brightness adjustment method, an electronic device, a storage medium, and a program product. Background Art

[0002] A naked-eye three-dimensional (3D) display device enables a user to view a 3D image without the aid of 3D glasses. The naked-eye 3D display device can process a two-dimensional (2D) image into a 3D image with a difference between the left eye and the right eye through a software algorithm, project the images corresponding to the left and right eyes into the user's left and right eyes respectively, and create a three-dimensional stereoscopic image by using the parallax principle.

[0003] However, since the user's left and right eyes need to receive two images respectively, due to the influence of ambient light, there will be a difference in the brightness of the images seen by the left and right eyes. As a result, when the user's brain synthesizes the three-dimensional stereoscopic image, there will be discomfort or the image will be unclear. Therefore, the current display effect of the naked-eye 3D display device when displaying images is poor, resulting in a poor user experience. Summary of the Invention

[0013] In the embodiments of the present disclosure, by judging the difference between the ambient light information entering the user's left eye and the ambient light information entering the user's right eye after the ambient light is reflected by the screen of the 3D display device, if there is an obvious difference between the ambient light information reflected to the user's left eye and the ambient light information reflected to the user's right eye, then the brightness of the left-eye image and the right-eye image displayed by the 3D display device can be adjusted, so as to adjust the light information entering the user's left eye (including the information of the ambient light and the information of the left-eye image) and the light information entering the user's right eye. Thus, by compensating the brightness of the left-eye image and the right-eye image displayed by the 3D display device, the brightness of the image seen by the user's left eye and the brightness of the image seen by the user's right eye can be balanced, thereby improving the display effect of the image displayed by the 3D display device and enhancing the user experience.

[0029] Before introducing the brightness adjustment method provided by the embodiments of the present disclosure in detail, the implementation environment and application scenarios of the embodiments of the present disclosure will be introduced first.

[0030] First, the application scenarios of the embodiments of the present disclosure will be introduced.

[0031] Currently, a 3D display device can process a 2D image into two different images (i.e., a left-eye image and a right-eye image) through a software algorithm, and then project the left-eye image into the user's left eye and the right-eye image into the user's right eye. By using the parallax principle, the effect of the user viewing a three-dimensional stereoscopic image is created, so that the user can see a 3D image without wearing 3D glasses, which has a strong visual impact.

[0032] Exemplarily, as Figure 1 shown, the inner display screen 101 of the 3D display device can simultaneously display a left-eye image (constituted by the picture shown in the shaded area in the figure) and a right-eye image (constituted by the picture shown in the white area in the figure). Under the influence of the parallax barrier (not shown in the figure), the left-eye image can be projected (represented by a dotted line in the figure) through the outer display screen 102 into the user's left eye 103, but cannot be projected into the user's right eye 104; and, under the influence of the parallax barrier, the right-eye image can be projected (represented by a solid line in the figure) through the outer display screen 102 into the user's right eye 104, but cannot be projected into the user's left eye 103.

[0033] That is, the core principle of the naked-eye 3D technology is to utilize the parallax characteristics of the human eye and project different images to the left eye and the right eye to enable the brain to synthesize a three-dimensional image. Specifically, the naked-eye 3D technology can be realized through the following several main technologies.

[0034] Slit grating technology: By adding a slit grating in front of the screen, the opaque stripes block one eye of the user, so that the other eye can see the corresponding image. That is, by using the parallax barrier principle, the visible pictures of the left eye and the right eye are separated through the parallax barrier (i.e., the slit grating). In this way, the left eye and the right eye can see different pictures respectively, thus forming a 3D effect.

[0035] Barrier-type technology: By using a switchable liquid crystal screen, a polarizing film, and a polymer liquid crystal layer, a vertical fine stripe pattern (i.e., a parallax barrier) is created. Through these stripes, the left eye and the right eye see different images respectively, thus achieving a 3D effect. That is, by placing a parallax barrier between the backlight module and the liquid crystal display (LCD) panel, using a switchable liquid crystal screen, a polarizing film, and a polymer liquid crystal layer, a series of vertical stripes with a direction of 90° and a width of dozens of micrometers are created to form a vertical fine stripe pattern. In the stereoscopic display mode, when the left-eye image is displayed on the liquid crystal screen, the opaque stripes will block the right eye; similarly, when the right-eye image is displayed on the liquid crystal screen, the opaque stripes will block the left eye, thus separating the visible images of the left eye and the right eye and enabling the user to see a 3D image.

[0036] Lenticular lens technology: Also known as micro-lenticular 3D technology, it projects the pixel points corresponding to the left eye and the right eye into the corresponding eyes respectively through the refraction principle of the lens. This technology does not affect the screen brightness and has a good display effect. That is, by covering a lenticular lens array on the surface of the screen, the pixel light on the screen is refracted and focused, so that the light rays emitted from different angles can be accurately projected into the left eye and the right eye of the user. Thus, the left eye and the right eye see slightly different images, and the brain constructs a stereoscopic picture based on the parallax information.

[0037] Directional light source technology: By combining two groups of light-emitting diodes (LEDs) with different angles distributed on the left and right sides, cooperating with a high-refresh-rate LCD panel and a reflection prism module, the picture is reflected to the left eye and the right eye respectively in an odd-even frame interleaved sorting manner. It can also achieve projecting the left-eye image and the right-eye image into the left eye and the right eye of the user respectively by attaching the backlight module behind the display panel and controlling the emission directions of the left-eye and right-eye parallax image light beams. When the image display panel displays the left-eye picture, the light source in the left-eye viewing area of the corresponding backlight module is turned on, and then the light beam is projected to the left eye through the backlight module, and the same is true for the right eye. Thus, by changing the direction and angle of the backlight source, the left eye and the right eye see different pictures respectively.

[0038] However, since the left eye and the right eye of the user need to receive two different images respectively, if affected by ambient light, there will be a difference in the brightness of the images seen by the left eye and the right eye, resulting in discomfort or unclear images when the brain synthesizes the three-dimensional stereoscopic image. That is, ambient light will affect the visual effect of the naked-eye 3D image.

[0039] Exemplarily, such as Figure 2As shown in the figure, after the ambient light is reflected by the screen surface (i.e., the outer display screen 201), part of the ambient light will be reflected into the user's eyes. Thus, some ambient light A 202 with specific incident directions and incident positions (represented by long dashed lines in the figure) will be reflected into the user's left eye 203, and some other ambient light B 204 with specific incident directions and incident positions (represented by short dashed lines in the figure) will be reflected into the user's right eye 205.

[0040] Based on this, if the ambient light intensity of ambient light A 202 is higher than that of ambient light B 204, after ambient light A 202 and ambient light B 204 are reflected by the screen, they enter the user's left eye 203 and right eye 205. Due to the natural physiological reaction, when the user's eyes are irradiated by light, the pupils of the eyes will contract. However, since the ambient light intensity of ambient light A 202 is higher than that of ambient light B 204, the contraction degree of the pupil of the user's left eye 203 is greater than that of the pupil of the user's right eye 205. As a result, the image brightness seen by the user's left eye 203 will be lower than the image brightness seen by the user's right eye 205.

[0041] If the left-eye image and the right-eye image displayed by the 3D display device have the same brightness, then the left eye 203 of the user is more affected by the stronger ambient light A 202, resulting in a greater contraction degree of the pupil, which will cause the brightness of the left-eye image seen by the user's left eye 203 to be lower. Furthermore, when the left-eye image and the right-eye image are synthesized by parallax in the brain to obtain a 3D image, since one eye sees a bright and clear image and the other eye sees a dim and blurred image, the stereoscopic imaging effect of the 3D image synthesized by parallax is poor, and the user will feel discomfort, reducing the user experience effect.

[0042] To solve the above problems, an embodiment of the present disclosure provides a brightness adjustment method. The brightness adjustment method provided by the embodiment of the present disclosure is applied to a 3D display device including a naked-eye 3D display screen. By adding a photosensitive layer (photosensitive module) in the naked-eye 3D display screen, the embodiment of the present disclosure detects and analyzes the ambient light to determine whether there is a difference in the light intensity entering the user's left eye and right eye after being reflected by the screen. If there is an obvious difference, the brightness of the left-eye image and the right-eye image displayed on the screen is adjusted (brightness compensation) to balance the difference in the brightness of the images seen by the user's left eye and right eye.

[0043] In the embodiments of the present disclosure, by determining the difference between the ambient light information (such as ambient light intensity) entering the user's left eye and the ambient light information entering the user's right eye after the ambient light passes through the screen reflection of the 3D display device, if there is an obvious difference between the ambient light information reflected to the user's left eye and the ambient light information reflected to the user's right eye, the brightness of the left-eye image and the right-eye image displayed by the 3D display device can be adjusted, so as to adjust the light information (including the information of the ambient light and the information of the left-eye image) entering the user's left eye and the light information entering the user's right eye. Thus, by compensating the brightness of the left-eye image and the right-eye image displayed by the 3D display device, the brightness of the image seen by the user's left eye and the brightness of the image seen by the user's right eye can be balanced, thereby improving the display effect of the image displayed by the 3D display device and enhancing the user experience.

[0044] The implementation environment of the embodiments of the present disclosure will be introduced below.

[0045] As Figure 3 shown, it is a schematic diagram of a brightness adjustment system provided by an embodiment of the present disclosure, which is applied to a 3D display device. The brightness adjustment system may include: a user 301 and a 3D display device 302. The 3D display device 302 can display a left-eye image and a right-eye image through the screen. The user 301 can view the left-eye image displayed on the screen of the 3D display device 302 through the left eye and view the right-eye image displayed on the screen of the 3D display device 302 through the right eye.

[0046] The 3D display device 302 can determine the first ambient light information of the ambient light reflected by the screen to the user's left eye and the second ambient light information of the ambient light reflected by the screen to the user's right eye.

[0047] The 3D display device 302 can also adjust the brightness of the displayed left-eye image and right-eye image based on the first ambient light information and the second ambient light information.

[0048] Among them, the 3D display device 302 can be a device including a naked-eye 3D display screen such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a personal digital assistant (PDA), a wearable electronic device, a vehicle-mounted device, etc. The embodiments of the present application do not make any restrictions on this.

[0049] Exemplarily, the 3D display device 302 may include a processor, a naked-eye 3D display screen, a camera, etc. Among them, the processor may include one or more processing units. For example, the processor may include an application processor, a modem processor, a graphics processor, an image signal processor, a controller, a video codec, a digital signal processor, a baseband processor, and / or a neural network processor, etc. Among them, different processing units may be independent devices or integrated in one or more processors.

[0050] The 3D display device 302 can display two images (left-eye image and right-eye image) through the naked-eye 3D display screen to achieve the display effect that users can view 3D images with the naked eye.

[0051] The naked-eye 3D display screen can implement the function of displaying two images based on technologies such as slit grating technology, barrier strip technology, lenticular lens technology, and pointed light source technology.

[0052] Of course, the 3D display device 302 provided in the embodiments of the present application may also include one or more devices such as a battery, an antenna, a mobile communication module, a wireless communication module, an audio module, a speaker, a receiver, a microphone, a headphone jack, a key, a motor, an indicator, and a SIM card interface. The embodiments of the present application do not impose any restrictions on this.

[0053] In a possible implementation manner, as Figure 4 shown, it is a schematic structural diagram of a 3D display device provided by an embodiment of the present disclosure. The 3D display device includes: a naked-eye 3D display screen 401, a light-sensing module 402, a storage module 403, a human eye positioning module 404, a light ray construction module 405, a processor 406, and a brightness control module 407.

[0054] The naked-eye 3D display screen 401 is used to display the left-eye image and the right-eye image (i.e., the naked-eye 3D image).

[0055] The light-sensing module 402 is disposed on the surface or inside of the naked-eye 3D display screen 401 and is used to collect the incident position, incident direction, and incident light intensity of the ambient light irradiating the naked-eye 3D display screen 401.

[0056] The storage module 403 is used to store the incident position, incident direction, and incident light intensity of the ambient light collected by the light-sensing module 402.

[0057] The human eye positioning module 404 determines the relative position information between the user's binocular eyes and the naked-eye 3D display screen 401 based on devices such as the camera, infrared sensor, or structured light sensor of the 3D display device, and further determines the gaze point position and gaze direction of the user's binocular eyes according to the pupil positions of the user's binocular eyes.

[0058] A light construction module 405, configured to determine, according to the incident position, incident direction, and incident light intensity of the ambient light stored in the storage module 403, and the relative position information of the user's binoculars and the autostereoscopic 3D display screen 401 determined by the binocular localization module 404, the ambient light information (ambient light intensity) of the effective ambient light that enters the user's left eye and the user's right eye respectively after the ambient light is reflected by the screen.

[0059] A processor 406, configured to determine, according to the ambient light information of the effective ambient light that enters the user's left eye and the user's right eye determined by the light construction module 405, whether the difference between the ambient light intensities that enter the user's left eye and the user's right eye is greater than a preset threshold.

[0060] A brightness control module 407, configured to control the brightness of the left-eye image and the right-eye image displayed on the autostereoscopic 3D display screen 401 in regions according to a certain ratio, or compensate for the brightness of the left-eye image and the right-eye image, according to the difference (light intensity difference) between the ambient light intensities that enter the user's left eye and the user's right eye.

[0061] After introducing the application scenarios and implementation environments of the embodiments of the present disclosure, the brightness adjustment method provided by the embodiments of the present disclosure will be described in detail below in combination with the above implementation environment.

[0062] The embodiments of the present disclosure provide a brightness adjustment method, which is applied to a 3D display device, such as Figure 5 shown, the brightness adjustment method may include: S501 - S502.

[0063] S501. Determine the ambient light information of the ambient light reflected by the screen of the 3D display device to the user's binoculars.

[0064] Wherein, the ambient light information includes first ambient light information corresponding to the left eye and second ambient light information corresponding to the right eye.

[0065] In the embodiments of the present disclosure, when there is ambient light (such as sunlight, lamp light, etc.) in the environment where the user uses the 3D display device, the ambient light irradiates on the screen of the 3D display device and is reflected into the user's binoculars, which will affect the user's viewing effect of the 3D image when using the 3D display device. Therefore, it is necessary to adjust the brightness of the image displayed by the 3D display device according to the ambient light information of the ambient light reflected by the screen to the user's binoculars, so as to reduce the influence of the ambient light on the image displayed by the 3D display device that the user views, and improve the display effect and user experience.

[0066] Exemplarily, such as Figure 6As shown in the figure, the screen of the 3D display device includes an outer display screen 601 and an inner display screen 602, and a photosensitive module 603 is included between the outer display screen 601 and the inner display screen 602. The left-eye image (constituted by the picture shown in the shaded area in the figure) displayed on the inner display screen 602 can, under the influence of a parallax barrier (not shown in the figure), pass through the outer display screen 601 and the photosensitive module 603 and be projected (represented by a dotted line in the figure) into the user's left eye 604. The right-eye image (constituted by the picture shown in the white area in the figure) displayed on the inner display screen 602 can, under the influence of the parallax barrier, pass through the outer display screen 601 and the photosensitive module 603 and be projected (represented by a solid line in the figure) into the user's right eye 605.

[0067] When there is ambient light in the environment, the ambient light A 606 (represented by a long dotted line in the figure) will be reflected into the user's left eye 604 after being reflected by the outer display screen 601, and the ambient light B 607 (represented by a short dotted line in the figure) will be reflected into the user's right eye 605 after being reflected by the outer display screen 601. Moreover, the ambient light A 606 and the ambient light B 607 can pass through the outer display screen 601 and irradiate the photosensitive module 603 to enable the photosensitive module 603 to detect the corresponding ambient light information (such as ambient light intensity).

[0068] In this way, the photosensitive module 603 can determine the first ambient light information reflected by the screen into the user's left eye and the second ambient light information reflected into the user's right eye.

[0069] In a possible implementation, the photosensitive module 603 can also be disposed on the surface of the outer display screen 601, and the present application does not make specific limitations on the setting position of the photosensitive module 603.

[0070] In a possible implementation, the ambient light information can include ambient light intensity, and can also include information such as ambient light color.

[0071] S502. Based on the first ambient light information and the second ambient light information, perform brightness adjustment on the images displayed by the 3D display device.

[0072] Among them, the images include a left-eye image and a right-eye image.

[0073] In a possible implementation, the brightness of the left-eye image and / or the right-eye image displayed by the 3D display device can be adjusted based on the first ambient light information and the second ambient light information.

[0074] It can be understood that the brightness of only one of the left-eye image and the right-eye image can be adjusted, or the brightness of both images can be adjusted.

[0075] In a possible implementation, the brightness of the left-eye image and / or the right-eye image displayed by the 3D display device may be adjusted based on the magnitude relationship between the first ambient light information and the second ambient light information; or, the brightness of the left-eye image and / or the right-eye image displayed by the 3D display device may be adjusted based on the difference between the first ambient light information and the second ambient light information (such as the difference in ambient light intensity).

[0076] In the embodiments of the present disclosure, by determining the difference between the ambient light information (such as ambient light intensity) entering the user's left eye and the ambient light information entering the user's right eye after the ambient light is reflected by the screen of the 3D display device, if there is an obvious difference between the ambient light information reflected to the user's left eye and the ambient light information reflected to the user's right eye, the brightness of the left-eye image and the right-eye image displayed by the 3D display device may be adjusted, thereby adjusting the light information (including the information of the ambient light and the information of the left-eye image) entering the user's left eye and the light information entering the user's right eye. In this way, by compensating the brightness of the left-eye image and the right-eye image displayed by the 3D display device, the brightness of the image seen by the user's left eye and the brightness of the image seen by the user's right eye may be balanced, thereby improving the display effect of the image displayed by the 3D display device and enhancing the user experience.

[0077] In some embodiments, the above S501 may specifically include:

[0078] S5011. Obtain the incident information of the first ambient light incident on the screen.

[0079] In a possible implementation, the first ambient light is all the light rays incident on the screen, that is, the first ambient light is all the light rays detected by the photosensing module 603.

[0080] In some embodiments, the incident information includes at least one of the following: incident position, incident direction, and incident light intensity.

[0081] It can be understood that the photosensing module 603 may determine information such as the incident position, incident direction, and incident light intensity of the ambient light based on the detected ambient light.

[0082] In a possible implementation, the incident information may further include information such as ambient light color.

[0083] In a possible implementation, after obtaining the incident information of the first ambient light, the photosensing module 603 may store the incident information of the first ambient light in the storage module of the 3D display device.

[0084] S5012. Obtain the gaze information of the user's binoculars on the screen.

[0085] In some embodiments, the gaze information includes: the gaze point positions of the user's two eyes on the screen, and / or, the gaze directions, where the gaze directions include: the left-eye gaze direction and the right-eye gaze direction.

[0086] In a possible implementation, when the user's two eyes gaze at the screen of the 3D display device, the 3D display device can determine the gaze information of the user's two eyes on the screen through devices such as cameras, infrared sensors, or structured light sensors.

[0087] In some embodiments, the above S5012 can be specifically implemented through the following steps:

[0088] S5012a. Obtain the relative position information between the user's two eyes and the screen, and the pupil positions in the user's two eyes.

[0089] In a possible implementation, the relative position information may include the distance between the user's two eyes and the screen in the first direction (the direction perpendicular to the screen), and the distance between the user's two eyes and the center point of the screen in the second direction (the direction perpendicular to the first direction).

[0090] It can be understood that the relative position information between the user's two eyes and the screen includes: the relative position information between the user's left eye and the screen and the relative position information between the user's right eye and the screen. The pupil positions in the user's two eyes include: the position of the pupil in the user's left eye and the position of the pupil in the user's right eye.

[0091] It should be noted that since there is a certain distance between the user's left eye and the user's right eye, there are differences between the relative position information of the user's left eye and the screen and the relative position information of the user's right eye and the screen, and there are also differences between the position of the pupil in the user's left eye and the position of the pupil in the user's right eye.

[0092] In a possible implementation, the gaze point positions and gaze directions of the user's two eyes can be further determined based on the pupil positions in the user's two eyes.

[0093] S5012b. Determine the gaze information of the user's two eyes on the screen based on the relative position information between the user's two eyes and the screen, and the pupil positions in the user's two eyes.

[0094] Exemplarily, as Figure 7 shown, taking the upper left corner of the screen 701 of the 3D display device as the origin, a coordinate system (two-dimensional coordinate system or three-dimensional coordinate system) is established on the surface of the screen 701 with the long side of the screen 701 as the X-axis and the short side as the Y-axis. The projections of the user's left eye 702 and the user's right eye 703 on the screen 701 are as Figure 7As shown. Taking the user's left eye 702 as an example, the ambient light A 704 irradiated onto the screen 701 is reflected by the fixation point 705 and then irradiates into the user's left eye 702. Based on the determined relative position information between the user's left eye 702 and the screen 701, the coordinate values of the projection of the user's left eye 702 in the coordinate system can be determined as (X 左 , Y 左 ), and the vertical distance h between the user's left eye 702 and the screen 701 can be determined, and the coordinate values of the fixation point 705 in the coordinate system can be determined as (X1, Y1). The left-eye fixation direction of the user's left eye 702 is the direction of the line connecting the user's left eye 702 and the fixation point 705. When the ambient light A 704 enters the user's left eye 702 after being reflected by the fixation point 705, the incident direction of the ambient light A 704 needs to satisfy the incident angle a as shown in the figure (that is, the included angle between the incident direction and the Y-axis is a), so that the ambient light A 704 can be reflected by the fixation point 705 in the screen 701 into the user's left eye 702.

[0095] In a possible implementation, according to the coordinate values of the projection of the user's left eye 702 in the coordinate system as (X 左 , Y 左 ) and the coordinate values of the fixation point 705 in the coordinate system as (X1, Y1), the left-eye fixation direction of the user's left eye 702 on the fixation point 705 can be determined in the coordinate system.

[0096] It should be noted that the incident direction of the ambient light A 704 is opposite to the left-eye fixation direction of the user's left eye 702 on the fixation point 705. Therefore, the reverse direction of the left-eye fixation direction of the user's left eye 702 on the fixation point 705 is the incident direction of the ambient light A 704 (that is, the incident angle a).

[0097] In a possible implementation, based on the coordinate values of the projection of the user's left eye 702 in the coordinate system as (X 左 , Y 左 ) and the coordinate values of the fixation point 705 in the coordinate system as (X1, Y1), the angular value of the incident angle a can be determined through Formula 1.

[0098] a = arctan[(X1 - X 左 ) / (Y1 - Y 左 )] Formula 1

[0099] Furthermore, combined with Figure 7 , such as Figure 8As shown, in the side view angle, the vertical distance between the user's left eye 702 and the screen 701 is h, and the distance Q between the projection point 801 of the user's left eye 702 and the fixation point 705 can be determined by Formula 2. When the ambient light 704 enters the user's left eye 702 after being reflected by the fixation point 705, the incident direction of the ambient light 704 also needs to satisfy the incident angle b as shown in the figure (i.e., the angle between the incident direction and the screen 701 is b).

[0100]

[0101] It can be understood that the incident angle b between the incident direction of the ambient light 704 and the screen 701 is equal to the reflection angle c between the reflected light of the ambient light 704 reflected by the fixation point 705 and the normal line of the screen 701.

[0102] In a possible implementation, the angular values of the incident angle b and the reflection angle c can be determined based on Formula 3.

[0103] b = c = arctan(Q / h) Formula 3

[0104] In this way, based on the determined incident angle a, incident angle b (or reflection angle c), the left-eye fixation direction of the user's left eye 702 on the fixation point 705, and the incident direction of the ambient light 704 reflected by the fixation point 705 to the user's left eye 702 can be accurately determined.

[0105] Similarly, for the method of determining the fixation information of the user's right eye 703 on the screen 701, reference can be made to the method of determining the fixation information of the user's left eye 702 on the screen 701, which will not be elaborated here.

[0106] In the embodiments of the present disclosure, by respectively determining the relative positional relationship between the user's left eye and the fixation point on the screen, and the relative positional relationship between the user's right eye and the fixation point on the screen, the left-eye fixation direction and the right-eye fixation direction of the user can be determined, and the incident direction of the light reflected to the user's left eye and the incident direction of the light reflected to the user's right eye can be determined. Thus, the light reflected to the user's left eye and the light reflected to the user's right eye can be accurately determined.

[0107] S5013. Based on the incident information of the first ambient light and the fixation information of the user's both eyes on the screen, determine the ambient light information of the ambient light reflected by the screen to the user's both eyes.

[0108] In a possible implementation, after determining the gaze information of the user's two eyes on the screen, the left-eye gaze direction and the right-eye gaze direction of the user can be determined based on the gaze information of the user's two eyes on the screen. Thus, based on the left-eye gaze direction and the right-eye gaze direction of the user, combined with the incident information (incident direction) of the first ambient light incident on the screen, the second ambient light reflected to the user's two eyes can be determined from the first ambient light.

[0109] In some embodiments, the ambient light information includes the ambient light intensity; the above S5013 can be specifically implemented through the following steps:

[0110] S5013a. Determine the second ambient light reflected to the user's two eyes from the first ambient light based on the incident position and incident direction of the first ambient light and the gaze information of the user's two eyes on the screen.

[0111] In some embodiments, the above S5013a can be specifically implemented through the following steps:

[0112] Based on the incident position of the first ambient light, determine the third ambient light whose incident position is at the gaze point position of the user's two eyes on the screen from the first ambient light; then, based on the incident direction of the third ambient light, determine the second ambient light whose incident direction matches the gaze direction of the user's two eyes on the screen from the third ambient light.

[0113] It should be noted that the first ambient light may include multiple beams of ambient light, and each beam of ambient light has its own incident position and incident direction.

[0114] Therefore, according to the incident position of each beam of ambient light included in the first ambient light, the ambient light whose incident position coincides with the gaze point position of the user's two eyes on the screen can be screened out (i.e., the third ambient light).

[0115] Furthermore, based on the incident direction of each beam of ambient light included in the third ambient light, the ambient light whose incident direction is opposite (i.e., matches) to the gaze direction of the user's two eyes on the screen (i.e., the direction determined by the incident angle a and the incident angle b) can be screened out (i.e., the second ambient light).

[0116] S5013b. Determine the ambient light intensity of the second ambient light reflected to the user's two eyes based on the incident light intensity of the second ambient light.

[0117] In a possible implementation, the incident light intensities of the ambient light reflected to the left eye of the user in the determined second ambient light can be accumulated to determine the ambient light intensity reflected to the left eye of the user; similarly, the incident light intensities of the ambient light reflected to the right eye of the user in the second ambient light can be accumulated to determine the ambient light intensity reflected to the right eye of the user.

[0118] In a possible implementation, the ambient light intensity reflected onto the user's left eye (right eye) can also be determined by calculating the average incident light intensity of the ambient light reflected onto the user's left eye (right eye).

[0119] In the embodiments of the present disclosure, based on the fixation point positions of the user's two eyes on the screen, the projection positions of the user's two eyes on the screen, and the vertical distance between the user's two eyes and the screen, the fixation directions of the user's two eyes can be determined. Then, based on the opposite directions of the fixation directions of the user's two eyes, combined with the incident positions and incident directions of all ambient light incident on the screen, the ambient light that can be reflected onto the user's two eyes can be determined from all the ambient light incident on the screen. Furthermore, based on the incident light intensity of each beam of ambient light reflected onto the user's two eyes, the ambient light intensities reflected onto the user's left eye and right eye can be determined. In this way, based on the positional relationship between the user's two eyes and the screen, the ambient light intensities reflected onto the user's two eyes can be accurately determined, and then it can be determined whether it is necessary to adjust the brightness of the image displayed by the 3D display device.

[0120] In some embodiments, the first ambient light information includes the first ambient light intensity, and the second ambient light information includes the second ambient light intensity; the above S502 can be specifically implemented through the following steps:

[0121] S5021. Determine the light intensity difference between the first ambient light intensity and the second ambient light intensity.

[0122] S5022. Adjust the brightness of the image displayed by the 3D display device based on the light intensity difference.

[0123] In some embodiments, the above S5022 can be specifically implemented through the following steps:

[0124] S5022a. When the first ambient light intensity is greater than the second ambient light intensity, increase the pixel brightness of the left-eye image and / or decrease the pixel brightness of the right-eye image based on the light intensity difference.

[0125] In a possible implementation, the greater the light intensity difference, the greater the difference between the pixel brightness of the left-eye image and the pixel brightness of the right-eye image. Therefore, the greater the light intensity difference, the higher the increase in the pixel brightness of the left-eye image, and / or the lower the decrease in the pixel brightness of the right-eye image.

[0126] It can be understood that when the first ambient light intensity is greater than the second ambient light intensity, it indicates that the brightness received by the user's left eye is higher than that received by the user's right eye. As a result, the pupil of the user's left eye contracts more than that of the user's right eye. Therefore, the brightness of the left-eye image seen by the user's left eye is lower than the brightness of the right-eye image seen by the user's right eye.

[0127] Therefore, the brightness of the left-eye image seen by the user can be balanced with the brightness of the right-eye image seen by the user by increasing the pixel brightness of the left-eye image and / or decreasing the pixel brightness of the right-eye image.

[0128] In a possible implementation, the pixel brightness of only the left-eye image can be increased while keeping the pixel brightness of the right-eye image unchanged; or, the pixel brightness of the left-eye image can be kept unchanged while only the pixel brightness of the right-eye image is decreased; or, both the pixel brightness of the left-eye image is increased and the pixel brightness of the right-eye image is decreased.

[0129] In some embodiments, the above S5022 can be specifically implemented through the following steps:

[0130] S5022b. When the first ambient light intensity is less than the second ambient light intensity, based on the light intensity difference, decrease the pixel brightness of the left-eye image and / or increase the pixel brightness of the right-eye image.

[0131] It can be understood that when the first ambient light intensity is less than the second ambient light intensity, it indicates that the brightness received by the user's left eye is lower than that received by the user's right eye. As a result, the pupil of the user's left eye contracts less than that of the user's right eye. Therefore, the brightness of the right-eye image seen by the user's right eye is lower than the brightness of the left-eye image seen by the user's left eye.

[0132] Therefore, the brightness of the left-eye image seen by the user can be balanced with the brightness of the right-eye image seen by the user by increasing the pixel brightness of the right-eye image and / or decreasing the pixel brightness of the left-eye image.

[0133] In a possible implementation, the pixel brightness of only the left-eye image can be decreased while keeping the pixel brightness of the right-eye image unchanged; or, the pixel brightness of the left-eye image can be kept unchanged while only the pixel brightness of the right-eye image is increased; or, both the pixel brightness of the left-eye image is decreased and the pixel brightness of the right-eye image is increased.

[0134] In an embodiment of the present disclosure, based on the difference between the first ambient light intensity of the ambient light reflected to the user's left eye and the second ambient light intensity of the ambient light reflected to the user's right eye, it is determined whether to adjust the brightness of the image displayed by the 3D display device. Thus, when the ambient light intensities of the ambient light reflected to the two eyes of the user are different, by adjusting the brightness of the pixel points of the corresponding image (left-eye image and / or right-eye image), the brightness of the left-eye image seen by the user's left eye can be made equal to the brightness of the right-eye image seen by the user's right eye. Therefore, the display effect of the image displayed by the 3D display device is improved, and the user experience is enhanced.

[0135] In still some other embodiments, the above S5022 can specifically be implemented through the following steps:

[0136] S5022c. When the absolute value of the light intensity difference is greater than the first preset threshold, based on the light intensity difference, adjust the brightness of the image displayed by the 3D display device.

[0137] In a possible implementation manner, the brightness of the image displayed by the 3D display device can be adjusted based on the light intensity difference only when the absolute value of the light intensity difference is greater than the first preset threshold.

[0138] That is, when the absolute value of the light intensity difference is less than or equal to the first preset threshold, it indicates that the difference in brightness between the left-eye image seen by the user's left eye and the right-eye image seen by the user's right eye is small, and there is no need to adjust the brightness of the image displayed by the 3D display device.

[0139] In still some other embodiments, when the incident light intensity of the ambient light incident on the target area of the screen is greater than the second preset threshold, adjust the brightness of the image in the target area.

[0140] In a possible implementation manner, considering that in some scenarios, the ambient light is relatively concentrated, thus forming a brighter light spot locally (in the target area) on the screen, which affects the clarity of the local image on the screen. Therefore, it can be determined whether to adjust (compensate) the brightness of only the image displayed in the target area by determining whether the incident light intensity of the ambient light incident on the target area of the screen is greater than the second preset threshold.

[0141] It should be noted that to implement the function of adjusting the loneliness connection of the image displayed in a partial area of the screen, the backlight module of the screen needs to be able to control the brightness of each area and each pixel on the hardware. Specifically, for small-sized screens, an Organic Light-Emitting Diode (OLED) screen can be used. Based on the principle of light emission of the OLED screen, under the action of voltage, positive and negative charges are injected and meet and recombine in the organic semiconductor material, releasing energy and causing the organic material to be in an excited state, thereby generating visible light. As a result, the brightness of each pixel can be independently controlled. For large-sized screens, a liquid crystal screen with full-array backlight can be selected. Full-array backlight means that the backlight system of a liquid crystal TV consists of multiple independently controlled LED lights. These LED lights are distributed behind the liquid crystal panel, and each LED light can independently adjust the brightness and on / off state. This design enables the 3D display device to precisely control the brightness of the image displayed in each area when displaying different scenes.

[0142] In the embodiment of the present disclosure, when the incident light intensity of the ambient light incident on the target area of the screen is greater than the second preset threshold, it indicates that the brightness of the image displayed in the target area is relatively low when the user's eyes view it. Therefore, only the brightness of the image displayed in the target area can be adjusted, without the need to adjust the brightness of all images, thereby reducing the task volume.

[0143] It can be understood that in order for the electronic device to implement the above functions, it includes the corresponding hardware structure and / or software module for executing each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiment of the present disclosure, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the way of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional technicians can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present disclosure.

[0144] The embodiment of the present disclosure can divide the function modules of the data sending end and the data receiving end according to the above method embodiment. For example, each function module can be divided corresponding to each function, or two or more functions can be integrated into one function module. The above integrated module can be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiment of the present disclosure is illustrative, only a logical function division, and there can be other division methods in actual implementation. The following takes the example of dividing each function module corresponding to each function for description.
