Description

Display control method and apparatus, display device and storage medium Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to display control methods, display control devices, display equipment, and storage media. Background Technology

[0002] When playing videos on a display device, the display brightness is primarily determined based on the brightness of the video content. However, during video production, ambient illumination can change dynamically; for example, the video creator can adjust the ambient illumination. In such cases, if the display brightness is still determined solely based on the brightness of the video content, it will be difficult to accurately reproduce the ambient illumination information within the video, thus affecting the video's display quality.

[0003] Summary of the Invention

[0006] According to a second aspect of the present disclosure, a display control device is provided, the device comprising: a processing module configured to determine a first display brightness for displaying the video on a display device based on the content brightness of the video; an acquisition module configured to acquire a first ambient illuminance at the time of video production and a second ambient illuminance of the display device; the processing module further configured to determine an adjustment coefficient based on the first ambient illuminance and the second ambient illuminance; and to adjust the first display brightness according to the adjustment coefficient to obtain a second display brightness; and a display module configured to display the video based on the adjusted display brightness.

[0007] According to a third aspect of the present disclosure, a display device is provided, comprising: one or more processors; wherein the display device is configured to perform the method of any one of the first aspect and any optional embodiments thereof.

[0008] According to a fourth aspect of the present disclosure, a storage medium is provided that stores instructions that, when executed on a communication device, cause the communication device to perform the method of any one of the first aspect and optional embodiments thereof.

[0009] According to a fifth aspect of the present disclosure, a program product is provided that, when executed by a communication device, causes the communication device to perform the method of any one of the first aspect and optional embodiments thereof.

[0010] According to embodiments of this disclosure, when displaying video, the display device can consider a first ambient illuminance during video production and a second ambient illuminance in the environment where the display device is located. Then, an adjustment coefficient is determined based on the first and second ambient illuminances. By adjusting the adjustment coefficient, the first display brightness of the video displayed by the display device is adjusted when the video is not encoded based on the first ambient illuminance. This ensures that when the video is displayed according to the adjusted second display brightness, it can reflect both the ambient illuminance during video production and the ambient illuminance of the environment where the display is located, thus guaranteeing a good display effect.

[0064] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0065] As shown in Figure 1A, the communication system 100 includes a production end 101 and a display end 102. The display end can be a display device, which can include any device with display function, such as a terminal, network device, server, etc. Among them, the network device includes at least one of the following: access network device and core network device.

Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0069] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0070] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0071] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0072] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A.

[0073] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0074] In some embodiments, when a video is played on a display device, the display brightness of the video is determined primarily based on the brightness of the video content. For example, the video type may include high dynamic range (HDR) video, or other types of video.

[0075] In some embodiments, the ambient illumination can be dynamically changed during video production. For example, if the video is a live stream, the ambient illumination during video production is the same as the ambient illumination during the live stream. The ambient illumination during the live stream can be changed. For example, the video producer can actively adjust the ambient illumination during the live stream, or the video producer can change the live stream position, causing the ambient illumination to change. This disclosure does not limit the way the ambient illumination is changed during video production.

[0076] Since the illumination during video production can change dynamically, if the display brightness is determined solely based on the brightness of the video content, the display brightness will fail to reflect information about the ambient illumination, thus affecting the video's display quality.

[0077] It should be noted that the video in this disclosure is not limited to live video, but may also include other types of video, such as recorded video. For ease of illustration, the following mainly uses live video as an example to illustrate the technical solution of this disclosure.

[0078] Figure 1B is a schematic diagram illustrating a video processing method according to an embodiment of the present disclosure.

[0079] As shown in Figure 1B, HDR video is used as an example.

[0080] On the video production side, the video can first undergo HDR pre-processing, such as adjusting the video display effect and adding watermarks to the video.

[0081] Videos pre-processed with HDR can be encoded with metadata, such as the first ambient illuminance at the time of video production, as well as the coordinates of the three primary colors, the maximum brightness of the video, etc. Metadata other than the first ambient illuminance can be referenced from relevant technologies, which will not be described in detail here.

[0082] The encoding result can be transmitted from the video production end to the video display end (e.g., the display device in the following embodiments). At the display end, the encoding result can be decoded first, for example, to obtain the video after HDR preprocessing, as well as metadata such as the first ambient illuminance (e.g., the coordinates of the three primary colors and the maximum brightness of the video).

[0083] Then, the display device can process the video based on metadata such as the first ambient illuminance to determine the second display brightness of the video displayed on the display device, taking the ambient illuminance into account.

[0084] In some embodiments, the display brightness of the video displayed on the display terminal needs to take into account both the ambient illuminance reflecting the video production environment (e.g., referred to as the first ambient illuminance) and the ambient illuminance of the environment in which the display terminal is located (e.g., referred to as the second ambient illuminance).

[0085] Therefore, as shown in Figure 1B, when the display terminal processes the video based on metadata such as the first ambient illuminance, it can further consider the second ambient illuminance to ensure that the determined second display brightness can reflect the ambient illuminance during video production and adapt to the ambient illuminance of the environment where the display terminal is located, thus ensuring a good display effect.

[0086] In some embodiments, the following embodiments of the display control method can be performed during the video processing at the display end shown in FIG1B based on metadata such as the first ambient illuminance and the second ambient illuminance.

[0087] Figure 2 is a schematic flowchart illustrating a display control method according to an embodiment of the present disclosure.

[0088] For example, the display control method can be executed by a display device, which can include any device with display function, including but not limited to terminals, network devices, and servers.

[0089] As shown in Figure 2, the display control method may include the following steps:

[0090] In step S201, the first display brightness of the video displayed on the display device is determined based on the brightness of the video content;

[0091] In step S202, the first ambient illuminance during video production and the second ambient illuminance of the display device are obtained, and an adjustment coefficient is determined based on the first ambient illuminance and the second ambient illuminance.

[0092] In step S203, the first display brightness is adjusted according to the adjustment coefficient to obtain the second display brightness;

[0093] In step S204, the video is displayed according to the adjusted display brightness.

[0094] It should be noted that display devices can display video on the screen; therefore, display brightness can also be described as screen brightness.

[0095] In some embodiments, such as based on the embodiment shown in FIG1B, the first display brightness refers to the brightness of the video displayed by the display device when the video is not encoded based on the first ambient illuminance, for example, it can be denoted as Y. p .

[0096] In some embodiments, the display device can determine a first display brightness corresponding to the content brightness of the video based on a first mapping relationship. The first mapping relationship is the mapping between the content brightness of the video and the first display brightness of the video displayed by the display device when the video is not encoded based on a first ambient illuminance. For example, the first mapping relationship can be determined by a function Y. p=f(Y) c ) characterization, where Y c This determines the brightness of the video content.

[0097] However, when considering both the first and second ambient illuminance, the mapping relationship between the content brightness of the video and the second display brightness of the video displayed on the display device (e.g., referred to as the second mapping relationship) will change relative to the first mapping relationship mentioned above.

[0098] In this embodiment, an adjustment coefficient can be determined based on the first ambient illuminance and the second ambient illuminance, and then the first display brightness can be adjusted using the adjustment coefficient to obtain the second display brightness. The second ambient illuminance can be obtained, for example, by monitoring ambient light using a sensor of the display device.

[0099] For example, the adjustment coefficient is denoted as h, and the second display brightness is denoted as Y. s The adjustment factor for the brightness of the first display can be expressed as Y. s =hY p It can be represented by the function Y s =g(Y p Determining the second display brightness accordingly ensures that, taking into account both the first and second ambient illuminance, the required second display brightness for displaying the video content on the display device can be accurately determined.

[0100] According to embodiments of this disclosure, when displaying video, the display device can consider a first ambient illuminance during video production and a second ambient illuminance in the environment where the display device is located. Then, an adjustment coefficient is determined based on the first and second ambient illuminances. By adjusting the adjustment coefficient, the first display brightness of the video displayed by the display device is adjusted when the video is not encoded based on the first ambient illuminance. This ensures that when the video is displayed according to the adjusted second display brightness, it can reflect both the ambient illuminance during video production and the ambient illuminance of the environment where the display is located, thus guaranteeing a good display effect.

[0101] It should be noted that the embodiments of this disclosure are compatible with display brightness determination methods that do not consider ambient illuminance. For example, if the display device determines that the metadata received from the manufacturing equipment includes a first ambient illuminance, it can determine the second display brightness based on the embodiments of this disclosure. Conversely, if the display device determines that the metadata received from the manufacturing equipment does not include the first ambient illuminance, it can determine the second display brightness based on the function Y. p =f(Y) c Determine the first display brightness and display the video according to the first display brightness.

[0102] Figure 3 is a schematic diagram illustrating the application of a display control method according to an embodiment of the present disclosure.

[0103] As shown in Figure 3, based on the embodiment shown in Figure 1B, the process of the display device processing the video may include tone mapping. For example, the display device may first perform tone mapping based on the case where the video is not encoded based on a first ambient illuminance. In this case, the metadata for tone mapping may not include the first ambient illuminance, and the display device may use the brightness of the displayed video determined based on the first mapping relationship as the first display brightness.

[0104] Figure 4 is a schematic diagram of a mapping relationship curve according to an embodiment of the present disclosure.

[0105] For example, the first mapping relationship can be represented as Y p =f(Y) c Therefore, the mapping relationship between the first display brightness and the content brightness of the video can be shown in Figure 4.

[0106] Figure 5 is a schematic diagram of another mapping relationship curve shown according to an embodiment of the present disclosure.

[0107] After obtaining the first display brightness, a first ambient illuminance and a second ambient illuminance can be introduced according to the embodiments of this disclosure. For example, an adjustment coefficient can be determined based on the first ambient illuminance and the second ambient illuminance, and then the first display brightness can be adjusted according to the adjustment coefficient to obtain the second display brightness.

[0108] For example, adjusting the brightness of the first display by adjusting the coefficient can be represented as Y. s =g(Y p )=Ys=g(f(Y c )), that is, Y s =g(Y p ), Y s =g(Y p This can also be called the second mapping relationship. The mapping relationship between the second display brightness and the content brightness of the video can be shown in Figure 5.

[0109] Furthermore, after determining the second display brightness, the display device can display the video based on the second display brightness. Additionally, the display device can perform post-processing on the video as needed, such as storage or resolution adjustment; this disclosure does not limit the scope of post-processing.

[0110] In some embodiments, the content brightness, first display brightness, and second display brightness of the video can be represented by a table. For example, taking n+1 sampling points as an example, the content brightness of n+1 points is Y. c0 To Y cn Then there can be n+1 corresponding first display brightness of Y p0 To Y pn The corresponding n+1 second display brightness is Y s0 To Ysn For example, the corresponding characters can be shown in Table 1 below:

[0111] Table 1

[0112] The following examples illustrate how a display device adjusts a first display brightness according to an adjustment coefficient to obtain a second display brightness.

[0113] In some embodiments, adjusting the first display brightness according to an adjustment coefficient to obtain the second display brightness includes: determining the ratio of the second ambient illuminance to the first ambient illuminance; and determining a first parameter based on the ratio, a preset maximum value, and a preset minimum value.

[0114] For example, the first ambient illuminance is denoted as E. r The second ambient illuminance is denoted as E. o The ratio is denoted as k.

[0115] Since the encoding range of the first ambient illuminance is not infinite, but within a certain range, for example, from 0 to 50,000 Lux, then 0 ≤ Er ≤ 50,000 Lux. In this case, the ratio k of the second ambient illuminance to the first ambient illuminance can be calculated using the following formula:

[0116] Therefore, it can be avoided that the molecule of k will not exceed 50,000, and that E can be avoided. o If the value of k is too large (e.g., greater than 50000), it will cause problems in the display process. Based on the above formula, the value of k ranges from 0.00002 (i.e., 1 / 50000) to 50000.

[0117] In some embodiments, although k can be used as an adjustment coefficient to determine the second display brightness, considering that adjusting the first display brightness based solely on a ratio k may result in relatively poor robustness of the system, in this embodiment, the first parameter can be determined based on k, and then the adjustment coefficient can be determined based on the first parameter.

[0118] In some embodiments, the display control method further includes:

[0119] When the first ambient illuminance is less than the second ambient illuminance, determine the preset maximum value of the adjustment coefficient (or determine the preset maximum value of the first parameter);

[0120] When the first ambient illuminance is greater than the second ambient illuminance, determine the preset minimum value of the adjustment coefficient (or determine the preset minimum value of the first parameter).

[0121] For example, the adjustment coefficient is denoted as h, and the preset maximum value of the adjustment coefficient is denoted as h. maxThe preset minimum value of the adjustment coefficient is denoted as h. min h max and h min The value is a preset value, which may be set by the display device manufacturer or by the display device user. It is an adjustable value, and this disclosure does not limit the specific setting method.

[0122] When the second ambient illuminance is less than the first ambient illuminance (k < 1), the second display brightness needs to be less than the first display brightness. In this case, the value of h is less than 1. min As the minimum value among all h values ​​less than 1, h can be determined based on Table 1 above, for example, when the second ambient illuminance is less than the first ambient illuminance. min .

[0123] When the second ambient illuminance is greater than the first ambient illuminance (k > 1), the second display brightness needs to be greater than the first display brightness. In this case, the value of h is greater than 1. max As the maximum value among all h values ​​greater than 1, h can be determined based on Table 1 above, for example, when the second ambient illuminance is greater than the first ambient illuminance. max .

[0124] Furthermore, when the first ambient illuminance is equal to the second ambient illuminance (k equals 1), the second display brightness is equal to the first display brightness, meaning that there is no need to adjust the first display brightness. In this case, the value of h is equal to 1.

[0125] In some embodiments, a preset maximum value and a preset minimum value are provided to ensure that the second display brightness increases as the first display brightness increases.

[0126] Since the second display brightness increases with the first display brightness, for example, with two first display brightness Y... p1 and Y p2 For example, Y s1 =g(Y p1 ), Ys2=g(Y p2 ), then in Y p1 ≤Y p2 In the case of Y s1 ≤Y s2 Therefore, when setting the values ​​of some parameters in advance, it is necessary to ensure that the second display brightness increases with the first display brightness to avoid conflicts between the set parameter values ​​and the actual situation.

[0127] In some embodiments, based on the ratio k and the preset maximum value h max and preset minimum value h min Determine the first parameter h k It can be represented as follows:

[0128] Where a = h max -h min b = 1 d = h min , where e is the natural constant.

[0129] Figure 6 is a schematic diagram illustrating the relationship between mapping curves according to an embodiment of the present disclosure.

[0130] As shown in Figure 6, when the video content brightness is relatively high, the first display brightness Yp and the second display brightness Ys are approximately equal, meaning that in this case, ambient illuminance has little impact on display brightness. However, when the content brightness is relatively low and not near 0, the difference between the first display brightness Yp and the second display brightness Ys is significant, meaning that in this case, ambient illuminance has a greater impact on display brightness.

[0131] For example, if the content brightness ranges from 0.00001 nit to 10000 nits, when mapped to the screen of a display device, the display brightness ranges from 0.001 nit to 1800 nits. In this case, a display brightness between 3 nits and 200 nits can be considered medium brightness. Within the medium brightness range, ambient illuminance has a significant impact on display brightness. Therefore, the preset maximum value h... max and preset minimum value h min The corresponding Yp and Ys should also be located within this medium brightness range.

[0132] It should be noted that in the embodiment shown in Figure 6, the case where the second ambient illuminance is greater than the first ambient illuminance, i.e., h is greater than 1, is taken as an example.

[0133] Figure 7 is a schematic diagram illustrating an adjustment coefficient according to an embodiment of the present disclosure.

[0134] In some embodiments, based on the mapping curve shown in Figure 6, the Y at each sampling point can be calculated. s With Y p The curve of h is plotted using the ratio of h to h, for example, the curve of h is shown in Figure 7. max The value is 4.

[0135] The following examples illustrate the application of the first parameter h. k The adjustment factor h is determined as an example.

[0136] In some embodiments, the display control method further includes: determining the maximum display brightness and the minimum display brightness of the display device, and determining at least one of the following:

[0137] The preset maximum value corresponds to the preset maximum brightness in the first display brightness setting;

[0138] The preset minimum value corresponds to the preset minimum brightness in the first display brightness.

[0139] To further improve robustness, when determining the adjustment coefficient h, the maximum and minimum display brightness of the display device can be further considered, where the maximum display brightness of the display device (e.g., denoted as Y) is... pmax ) and minimum display brightness (e.g., denoted as Y) pmin ), are inherent parameters of the display device.

[0140] Furthermore, the preset maximum value corresponding to the preset maximum brightness in the first display brightness can be determined (e.g., denoted as Y). phmax It can also determine the preset minimum brightness corresponding to the first display brightness (e.g., denoted as Y). phmin For example, Y phmax It can be used to determine h and Y when the second ambient illuminance is greater than the first ambient illuminance. phmin It can be used to determine h when the second ambient illuminance is less than the first ambient illuminance.

[0141] In some embodiments, when the first ambient illuminance is less than the second ambient illuminance, an adjustment factor is determined based on the first ambient illuminance and the second ambient illuminance, including at least one of the following:

[0142] When the first display brightness is equal to the preset maximum brightness, the adjustment coefficient is determined to be equal to the first parameter;

[0143] When the first display brightness is greater than or equal to the minimum display brightness and less than the preset maximum brightness, the adjustment coefficient is determined based on the first parameter, the preset maximum brightness and the minimum display brightness.

[0144] When the first display brightness is greater than the preset maximum brightness but less than or equal to the maximum display brightness, the adjustment coefficient is determined based on the first parameter, the preset maximum brightness, the maximum display brightness, and the preset maximum value.

[0145] As shown in the embodiment in Figure 7, when the second ambient illuminance is greater than the first ambient illuminance, the curve of h is based on h. max It is a function that is first monotonically increasing and then monotonically decreasing, with extreme points.

[0146] Therefore, for the extreme point h max That is, the first display brightness is equal to the preset maximum brightness (Y). p =Y phmax In the case of h, it can be determined that the adjustment coefficient is equal to the first parameter, that is, h = h k .

[0147] Furthermore, for the cases where the first display brightness is greater than or equal to the minimum display brightness but less than the preset maximum brightness, and for the cases where the first display brightness is greater than the preset maximum brightness but less than or equal to the maximum display brightness, the function corresponding to the adjustment coefficient h can be determined respectively.

[0148] For example, the first display brightness is greater than or equal to the minimum display brightness, but less than the preset maximum brightness (Y). pmin ≤Y p <Y phmax In this case, the adjustment coefficient can be determined based on the first parameter, the preset maximum brightness, and the minimum display brightness. For example, the calculation method can be as follows:

[0149] For example, the first display brightness is greater than the preset maximum brightness, but less than or equal to the maximum display brightness (Y). phmax <Y p ≤Y pmax In this case, the adjustment coefficient can be determined based on the first parameter, the preset maximum brightness, the maximum display brightness, and the preset maximum value. For example, the calculation method can be as follows:

[0150] In the two calculation formulas above, α and β can be preset values ​​or adjustable values. For example, the value range of α is greater than 0, and the value range of β is less than or equal to 1. Furthermore, α and β need to satisfy the condition that the second display brightness increases as the first display brightness increases.

[0151] Based on the above embodiments, it can be seen that when the second ambient illuminance is greater than the first ambient illuminance, h can be calculated as follows:

[0152] In some embodiments, when the first ambient illuminance is greater than the second ambient illuminance, an adjustment factor is determined based on the first ambient illuminance and the second ambient illuminance, including at least one of the following:

[0153] The adjustment coefficient is set to equal the first parameter, where the first display brightness is equal to the preset minimum brightness;

[0154] The adjustment coefficient is determined based on the first display brightness, the first parameter, the preset minimum brightness, and the minimum display brightness, wherein the first display brightness is greater than or equal to the minimum display brightness and less than the preset minimum brightness;

[0155] The adjustment coefficient is determined based on the first display brightness, the first parameter, the preset minimum brightness, the maximum display brightness, and the preset minimum value, wherein the first display brightness is greater than the preset minimum brightness and less than or equal to the maximum display brightness.

[0156] For example, the calculation method for h when the second ambient illuminance is greater than the first ambient illuminance can be used as a reference to determine the calculation method for h when the first ambient illuminance is greater than the second ambient illuminance. For example, when the first ambient illuminance is greater than the second ambient illuminance, the calculation method for h can be as follows:

[0157] In some embodiments, adjusting the first display brightness according to an adjustment coefficient to obtain a second display brightness includes: determining the product of the adjustment coefficient and the first display brightness; and determining that the second display brightness is equal to the minimum value between the product and the maximum display brightness.

[0158] Considering that the display brightness of a display device has extreme values, such as the maximum display brightness Y of the display device. pmax After adjusting the first display brightness using an adjustment factor, the second display brightness should not exceed Y. pmax Therefore, when determining the relationship between the second display brightness and the first display brightness, the maximum display brightness needs to be considered.

[0159] For example, the second display brightness can be determined by multiplying the first display brightness by an adjustment factor, but since the second display brightness should not exceed Y... pmax Therefore, we can take the above product and Y. pmax The minimum value in the range is used as the second display brightness. For example, the second display brightness Y... s The calculation method can be shown below:

[0160] Y s =min(h·Y) p ,Y pmax ).

[0161] Therefore, if the product of the first display brightness and the adjustment coefficient is less than or equal to Y... pmax In cases where the product of the first display brightness and the adjustment coefficient is greater than Y, this product can be used as the second display brightness. pmax In this case, then Y pmax As a second display brightness, it ensures that the second display brightness does not exceed the maximum brightness that the display device can display, and ensures that the display device can accurately display video at the second display brightness.
