[0073] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0074] Application Overview

[0075] As mentioned above, in order to improve users' Internet audio-visual experience, the following three approaches are mainly used.

[0076] First, improve the display quality of the content itself by carefully producing the content medium; second, transcode the content through excellent transcoding technology to minimize the loss of content quality during the transcoding process; and, use high-quality audio and video playback equipment as much as possible.

[0077] However, even if all the above conditions are met, in many cases, it is still found that the content played by the user through the terminal device is far from the desired effect. For example, when a user watches a movie through a video application on a mobile terminal such as a smartphone, it is difficult to get the same viewing experience as watching a movie in a theater.

[0078] The inventor of the present application has found through research that, although some optimizations have been made to the display content in the current terminal players, these optimizations do not take into account the factors of the display content when it is finally produced. For example, after the film is produced, after the film editing, aesthetic color grading and other post-production adjustments, the director finally needs to review the film effect of the entire film, and the device used by the director to review the film usually has specific parameter settings.

[0079] In response to the above technical problems, the basic concept of the present application is to adjust other display parameters based on the production reference parameters of the display content and the key parameters in the current display parameters, so as to adjust the presentation effect of the display content to be the same as the display effect based on the production reference parameters to restore the production effect.

[0080] Specifically, the display control method, device and electronic device for restoring the production effect provided by the present application first determine the production reference parameters of the display content, then obtain the current display parameters of the display content, and finally adjust other display parameters in the current display parameters based on the reference display parameters in the current display parameters and the reference reference parameters in the production reference parameters, so that the display content is presented with the display effect according to the production reference parameters. In this way, the effect of the display content when it was produced can be restored to the user, thereby improving the user's audio-visual experience.

[0081] Here, those skilled in the art can understand that the display content in the solution of the present application is not limited to movies played through video applications, but also includes various types of display content displayed through other display devices. For example, the display content can be a TV series or other program played through a smart phone, a tablet, or a TV, and the present application does not intend to impose any limitation on this.

[0082] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0083] Exemplary Methods

[0084] [First embodiment]

[0085] Figure 1 The figure illustrates a flow chart of a display control method for restoring a production effect according to the first embodiment of the present application.

[0086] like Figure 1 As shown, according to the first embodiment of the present application, the display control method for restoring the production effect includes: S110, determining the production reference parameters of the display content; S120, obtaining the current display parameters of the display content; and S130, adjusting other display parameters in the current display parameters based on the reference display parameters in the current display parameters and the reference reference parameters in the production reference parameters, so that the display content is presented with the display effect according to the production reference parameters.

[0087] In step S110, the production reference parameters of the display content are determined. As described above, after the display content such as a movie is shot, other post-processing such as film editing and aesthetic color grading is required, which are usually completed by dedicated post-production personnel. After the post-production is completed, the director of the film or the producer of other types of programs will watch the film and review it. Therefore, in order to restore the production effect, in the embodiment of the present application, it is necessary to determine the production reference parameters when reviewing after the display content is produced.

[0088] One of the main parameters in the above production benchmark parameters is the brightness of the display device that displays the display content during the review, which is particularly obvious in film production. Because usually, movies are watched by audiences in theaters, and the theater environment is usually dark, and directors usually watch the finished film on specific devices in order to obtain a realistic playback effect.

[0089] At present, the devices that directors use to watch finished films are mainly divided into two types: Standard Dynamic Range (SDR) and High Dynamic Range (HDR), and the brightness of these two display devices is different. Specifically, the brightness of SDR display devices is 100 nits, while the brightness of HDR display devices is 1000 nits. Therefore, the production review brightness of the display content when it is finally produced can be determined according to the format of the display content.

[0090] That is, in the display control method for restoring the production effect according to the embodiment of the present application, determining the production reference parameters of the display content includes: determining whether the display content is in a standard dynamic range format or a high dynamic range format; in response to determining that the display content is in a standard dynamic range format, determining that the production review brightness of the display content is 100 nits; and, in response to determining that the display content is in a high dynamic range format, determining that the production review brightness of the display content is 1000 nits.

[0091] Here, those skilled in the art may understand that the production reference parameters in the embodiments of the present application may include other parameters, such as picture contrast or audio loudness, in addition to the production review brightness of the display content when the production is finally completed.

[0092] In step S120, the current display parameters of the display content are obtained. As described above, when considering the brightness of the display device, the device on which the director watches the finished film is usually 100 nits or 1000 nits, while the terminal device used by the user to watch the film, such as a smartphone, tablet computer, TV, etc., depends on other devices and usually has different brightness.

[0093] Specifically, the current display brightness of smartphones is 200 nits to 1000 nits, the display brightness of tablet computers is 200 nits to 500 nits, and the display brightness of home TVs and monitors is 150 nits to 1000 nits.

[0094] In addition, taking into account the different terminal devices currently used by users, in order to obtain accurate display parameters as much as possible, in an embodiment of the present application, a database containing brightness parameters and other display parameters is pre-established according to the device model parameters of the terminal device, and then the current display parameters are obtained by querying the database.

[0095] Therefore, in the display control method for restoring the production effect according to the embodiment of the present application, the reference benchmark parameter is the production review brightness of the display content when the final production is completed; and, the reference display parameter is the brightness setting parameter of the current display device that displays the display content.

[0096] As mentioned above, although the current main production review brightness is 100 nits or 1000 nits depending on the format of the display content, other devices may also have different brightness, such as 200 nits, etc. The embodiments of the present application are not intended to impose any limitations on this.

[0097] Here, the brightness setting parameter refers to the maximum value of the brightness setting of the current display device. Taking the brightness setting parameter as 200 nits as an example, it indicates that the brightness of the terminal device can be adjusted between 0-200 nits. For example, when the backlight of the terminal device is adjusted to the maximum, the display brightness of the terminal device is 200 nits. Generally, for devices of the same model, their brightness setting parameters are fixed, so the brightness setting parameters can be obtained through the device model parameters of the terminal device.

[0098] In addition, corresponding to the brightness setting parameter, the terminal device also has a brightness versus signal level curve, which is a photoelectric conversion type curve used to represent the relationship between brightness and signal level. Since the size of the signal level is directly related to the human eye's perception of the screen, different display modes perceived by the human eye can be set by adjusting the brightness versus signal level curve, such as a bright color mode, a soft color mode, etc.

[0099] It should be noted that in the embodiment of the present application, the brightness versus signal level curve corresponding to the brightness setting parameter of the current display device displaying the display content is not related to the backlight brightness of the terminal device such as a smart phone, that is, the screen brightness usually adjusted by the user, but also depends on the characteristics of the display panel, such as the light transmittance characteristics of the liquid crystal layer, etc. When the user adjusts the brightness on the terminal device, it is actually moving on this brightness versus signal level curve.

[0100] Therefore, in the display control method for restoring the production effect according to the embodiment of the present application, the reference benchmark parameters further include a first brightness versus signal level curve corresponding to the production review brightness when the display content is finally produced; and, the reference display parameters further include a second brightness versus signal level curve corresponding to the brightness setting parameters of the current display device.

[0101] Moreover, this brightness versus signal level curve cannot usually be obtained directly from the terminal device, or even from the terminal device manufacturer, but needs to be measured under specific conditions using a dedicated brightness measurement tool. Therefore, for various current display devices, it is necessary to pre-test their brightness versus signal level curves and establish a database.

[0102] Therefore, in the display control method for restoring the production effect according to the embodiment of the present application, obtaining the current display parameters of the display content includes: determining the device model parameters of the current display device; and, based on the device type and the model parameters, querying a preset database to obtain the brightness setting parameters of the current display device.

[0103] Of course, those skilled in the art can also understand that in the embodiment of the present application, the display parameters of the display device are not limited to brightness, and depend on the production reference parameters obtained in step S110. The reference display parameters can also be other parameters of the display device.

[0104] In step S130, other display parameters in the current display parameters are adjusted based on the reference display parameters in the current display parameters and the reference reference parameters in the production reference parameters, so that the display content is presented with a display effect according to the production reference parameters.

[0105] Specifically, when the reference display parameter and the reference benchmark parameter are display brightness of the display device, the other display parameters include at least one of contrast, chromaticity, color difference, and color shift. That is, in accordance with different display brightnesses, in the embodiment of the present application, only one other display parameter may be adjusted, or multiple other display parameters may be adjusted simultaneously, so that the display content is presented with a display effect according to the production benchmark parameter.

[0106] Figure 2 FIG. 1 is a schematic diagram showing a relationship curve between different display parameters according to an embodiment of the present application. Figure 2 As shown, the horizontal axis represents the value of parameter 1, for example, it can be a brightness parameter in nits, or a chromaticity parameter in the range of 0-255, or other parameters, and similarly, the vertical axis represents the value of parameter 2. In the simplest case, such as Figure 2 As shown in curve a in , parameter 1 and parameter 2 present a linear relationship, but in most cases, parameter 1 and parameter 2 present a nonlinear relationship, such as Figure 2 As shown in curve b and curve c.

[0107] Figure 3 FIG. 2 is a schematic diagram illustrating a first example of parameter adjustment according to an embodiment of the present application. Figure 3 As shown, for example, if the display brightness (horizontal axis in the figure) and the contrast (vertical axis in the figure) are linearly related. When the production review brightness is 100 nits, the contrast value is P1. Then, when the current brightness of the current display device of the display content is 400 nits, the contrast value is adjusted to P2 accordingly, so that the display effect of the display content is consistent with the effect based on the production review brightness of 100 nits.

[0108] Figure 4 FIG. 2 is a schematic diagram illustrating a second example of parameter adjustment according to an embodiment of the present application. Figure 4 As shown, for example, if the display brightness (horizontal axis in the figure) and the chromaticity (for example, at least one of R, G, B) (vertical axis in the figure) are nonlinearly related. When the production review brightness is 100 nits, the value of the contrast is V1, then when the current brightness of the current display device of the display content is 400 nits, the value of the contrast is adjusted to V2 accordingly, so that the display effect of the display content is consistent with the effect according to the production review brightness of 100 nits.

[0109] Figure 5 The figure shows a schematic diagram of adjusting the brightness to signal level curve according to an embodiment of the present application. Figure 5(A) shows the first brightness versus signal level curve of the display content obtained when the final production is completed. Here, the horizontal axis of the curve represents brightness, and as mentioned above, in the SDR format, the maximum is 100 nits, and the vertical axis represents the signal level, which ranges from 0 to 255. Therefore, in the case of a maximum brightness of 100 nits, the signal level is 255.

[0110] Figure 5 (B) shows the third brightness versus signal level curve corresponding to the first brightness versus signal level curve at another brightness, that is, the brightness setting parameter of the current display device. Here, those skilled in the art can understand that the brightness versus signal level curve at a certain maximum brightness can be calculated by an existing algorithm. That is, Figure 5 Under the third brightness versus signal level curve shown in (B), the display effect of the display content viewed by the user through the current display device is the same as that of the display content when it is finally produced. For example, for a filmed movie, if the display setting parameter of the terminal device used by the user is 300 nits, and the playback device used by the director when the film is finally reviewed is 100 nits, then when the director's playback device has a first brightness versus signal level curve corresponding to 100 nits, and the terminal device used by the user has a third brightness versus signal level curve corresponding to the first brightness versus signal level curve at 300 nits, the user can see on the terminal exactly the same effect as what the director sees on the playback device, that is, the most realistic effect that the director wanted to present when shooting the film is completely restored.

[0111] However, as described above, for the terminal device actually used by the user, depending on the terminal device manufacturer, the brightness versus signal level curve may be adjusted to different curves of various shapes to achieve a specific visual effect. For example, when the brightness versus signal level curve is adjusted to be relatively gentle, the displayed visual effect is relatively soft, and when the brightness versus signal level curve is adjusted to be relatively undulating, the displayed visual effect color is relatively distinct.

[0112] Therefore, in order to present the same effect as the display content when it is finally produced, Figure 5 The original second brightness versus signal level curve of the current display device used by the user as shown in (C) is adjusted to be as follows Figure 5 The third brightness versus signal level curve is shown in (B).

[0113] That is, in the display control method for restoring the production effect according to the embodiment of the present application, adjusting other display parameters in the current display parameters based on the reference display parameters in the current display parameters and the reference benchmark parameters in the production benchmark parameters includes: determining a third brightness-to-signal level curve corresponding to the first brightness-to-signal level curve under the brightness setting parameters based on the first brightness-to-signal level curve; and adjusting the second brightness-to-signal level curve of the current display device to the third brightness-to-signal level curve.

[0114] Here, the adjustment of the brightness to signal level curve can be based on the current brightness to signal level curve, that is, the second brightness to signal level curve as described above, and the target brightness to signal level curve, that is, the reverse adjustment of the third brightness to signal level curve as described above. It is also possible to directly set the brightness to signal level curve to the target brightness to signal level curve when the display device leaves the factory. That is to say, in the embodiment of the present application, adjusting the brightness to signal level curve of the current display device includes setting the third brightness to signal level curve corresponding to the first brightness to signal level curve under the brightness setting parameters when the current display device leaves the factory.

[0115] When the brightness versus signal level curve of the current display device is reversely adjusted, it is first necessary to reversely transform the brightness versus signal level curve to obtain the initial corresponding relationship between the signal level and the brightness of the current display device, for example, a linear relationship. As described above, for various terminal devices, adjustments are made based on the initial corresponding relationship between the signal level and the brightness. For example, if it is necessary to enhance the color contrast, the linear relationship curve between the signal level and the brightness is pulled up to make the signal level curve steeper under low brightness conditions and the signal level flatter under high brightness conditions. Therefore, after restoring the brightness versus signal level curve of the current display device to the initial curve, the initial curve can be adjusted to the desired target brightness versus signal level curve.

[0116] Therefore, in the display control method for restoring the production effect according to the embodiment of the present application, adjusting the second brightness-to-signal level curve of the current display device to the third brightness-to-signal level curve includes: inversely transforming the second brightness-to-signal level curve to obtain the initial correspondence between the signal level and the brightness of the current display device; and adjusting the initial correspondence between the signal level and the brightness of the current display device to the third brightness-to-signal level curve.

[0117] It should be emphasized that the adjustment of the brightness to signal level curve in the embodiment of the present application is different from the adjustment of brightness in various existing terminal devices. As described above, the adjustment of brightness in existing terminal devices is actually on a fixed brightness to signal level curve, and the signal level corresponding to the vertical axis is obtained by adjusting the brightness corresponding to the horizontal axis of the curve, thereby presenting a different feeling to the user. Therefore, if the brightness to signal level curve under the brightness setting parameters of the user's current display device is not adjusted, it is impossible to restore the display content when it is completed, for example, the effect that the film is to be presented when the director reviews the final film, and thus it is impossible to obtain a completely real viewing experience.

[0118] In addition, in the display control method for restoring the production effect according to the embodiment of the present application, in addition to considering the difference between the display parameters of the current display device displaying the display content and the production reference parameters, the influence of the environmental factors of the current display device on the display effect can also be further considered.

[0119] That is to say, in the display control method for restoring the production effect according to the embodiment of the present application, adjusting other display parameters in the current display parameters based on the reference display parameters in the current display parameters and the reference benchmark parameters in the production benchmark parameters includes: adjusting other display parameters in the current display parameters based on the reference display parameters in the current display parameters, the reference benchmark parameters in the production benchmark parameters and the environmental parameters of the current display device displaying the display content.

[0120] Specifically, the environmental parameters may include ambient brightness, ambient loudness, and other environmental factors. With respect to ambient brightness factors, the display content may be rendered in a scene-based manner for different scenes, such as outdoor scenes, office scenes, subway scenes, etc., and various display parameters may be intelligently adapted so that the presentation effect of the display content is consistent with the production effect. In addition, with respect to ambient loudness factors, intelligent sound field adaptation may be performed, such as loudness standardization, automatic voice recognition, and dialogue protection.

[0121] [Second embodiment]

[0122] Figure 6 The figure illustrates a flow chart of a display control method for restoring production effects on a server side according to a second embodiment of the present application.

[0123] like Figure 6As shown, according to the second embodiment of the present application, the display control method for restoring the production effect includes: S210, determining the production review brightness of the display content when the final production is completed and its corresponding production brightness versus signal level curve; S220, calculating the target brightness versus signal level curve at the target display brightness based on the production brightness versus signal level curve; and S230, sending a display control instruction, the display control instruction is used to control the display device that displays the display content to be set to the target brightness versus signal level curve.

[0124] Specifically, taking a movie as an example, in step S210, the brightness (100 nits or 1000 nits) of the movie when the director completes the review after production and its corresponding brightness versus signal level curve are determined.

[0125] Then, in step S220, a brightness versus signal level curve at a target display brightness is calculated based on the brightness versus signal level curve of 100 nits. For example, if the target display brightness is 300 nits, the corresponding brightness versus signal level curve at 300 nits is calculated. Here, those skilled in the art can understand that in the present embodiment, the target display brightness is a preset universal display brightness, for example, 300 nits regardless of the display device, and in other embodiments, for example, in the embodiments described above, the target display brightness can also be a brightness setting parameter determined for the current display device, for example, depending on different devices, it can be 200 nits, 500 nits, 1000 nits, etc.

[0126] Finally, in step S230, a display control instruction is sent, wherein the display control instruction is used to control a display device that displays the display content so that the display device is set to the target brightness versus signal level curve, that is, the target brightness versus signal level curve at 300 nits as described above.

[0127] In the above-mentioned display control method for restoring the production effect on the server side, determining the production review brightness of the display content when the final production is completed and its corresponding production brightness versus signal level curve includes: determining that the display content is in a standard dynamic range format or a high dynamic range format; in response to determining that the display content is in a standard dynamic range format, determining that the production review brightness of the display content is 100 nits; and, in response to determining that the display content is in a high dynamic range format, determining that the production review brightness of the display content is 1000 nits.

[0128] In the above-mentioned display control method for restoring the production effect on the server side, the target display brightness is one or more preset target display brightnesses.

[0129] In the above-mentioned display control method for restoring the production effect on the server side, the target display brightness is the initial display brightness of the display content displayed by the terminal.

[0130] That is, in the second embodiment of the present application, after determining the production reference parameters of the display content, specifically, the production review brightness of the display content when the final production is completed and its corresponding production brightness to signal level curve, the target brightness to signal level curve can be directly determined according to the production brightness to signal level curve. For example, the production brightness to signal level curve corresponds to a brightness of 100 nits, and the target brightness to signal level curve corresponds to one or more brightnesses, such as 200 nits, 300 nits, 500 nits, 1000 nits, etc. Then, when the display content is displayed by a display device, regardless of the display parameters of the display device itself, the brightness to signal level curve of the display device is adjusted to a default one of the target brightness to signal level curves, such as 300 nits. In this way, although the target brightness to signal level curve is not optimized for the display content for different display devices, it can still improve the restoration degree of the display content compared with the original brightness to signal level curve of the display device.

[0131] In addition, the target display brightness may depend on different terminals. For example, if the brightness reference parameter of a terminal is 600 nits, the server may calculate the target brightness versus signal level curve at 600 nits after receiving the initial display brightness of the terminal, i.e., 600 nits.

[0132] In the above-mentioned display control method for restoring the production effect on the server side, calculating the target brightness versus signal level curve at the target display brightness based on the production brightness versus signal level curve includes: determining the device model parameters of the terminal; querying a preset database based on the device model parameters to obtain the initial display brightness of the terminal; and calculating the target brightness versus signal level curve at the target display brightness based on the production brightness versus signal level curve.

[0133] Here, those skilled in the art can understand that other details of the display control method for restoring the production effect on the server side according to the second embodiment of the present application are exactly the same as the corresponding details of the display control method for restoring the production effect according to the first embodiment of the present application, so in order to avoid redundancy, they will not be repeated.

[0134] [Third embodiment]

[0135] Figure 7 The figure illustrates a flow chart of a display control method for restoring a production effect of a terminal according to the third embodiment of the present application.

[0136] like Figure 7 As shown, according to the third embodiment of the present application, the display control method for restoring the production effect of the terminal includes: S310, receiving a display control instruction, the display control instruction is used to instruct the terminal displaying the display content to be set to a target brightness versus signal level curve, the target brightness versus signal level curve is a target brightness versus signal level curve at a target display brightness, and is calculated based on the production brightness versus signal level curve, the production brightness versus signal level curve is a brightness versus signal level curve when the final production of the display content is completed and corresponds to the production review brightness; and S320, setting the target brightness versus signal level curve based on the display control instruction.

[0137] In the above-mentioned display control method for restoring the production effect of a terminal, the target display brightness is one or more preset target display brightnesses.

[0138] In the above-mentioned display control method for restoring the production effect of the terminal, setting the target brightness versus signal level curve based on the display control instruction includes: determining the number of preset target display brightnesses; and, in response to determining that the number of preset target display brightnesses is one, setting the terminal to the preset target brightness versus signal level curve.

[0139] In the above-mentioned display control method for restoring the production effect of the terminal, setting the target brightness versus signal level curve based on the display control instruction further includes: in response to determining that the number of the preset target display brightnesses is multiple, determining the brightness setting parameter of the terminal; comparing the brightness setting parameter with the preset multiple target display brightnesses to determine the candidate target display brightness among the multiple target display brightnesses that is closest to the brightness setting parameter; and setting the terminal to a target brightness versus signal level curve corresponding to the candidate target display brightness.

[0140] In the above-mentioned display control method for restoring the production effect of the terminal, the target display brightness is the initial display brightness of the terminal displaying the display content.

[0141] That is to say, because as mentioned above, when calculating the target brightness to signal level curve at the server side, one or more preset target brightness to signal level curves corresponding to one or more target display brightnesses may be calculated, such as 200 nits, 300 nits, 500 nits, 1000 nits, and these target brightness to signal level curves are sent to the terminal and stored in a preset curve library in the terminal, such as a predetermined curve library of a video playback application. In this case, when the terminal sets the target brightness to signal level curve, it is necessary to determine the number of curves in the curve library. If the number of curves is one, the terminal is set to the target brightness to signal level curve. And if the number of curves is multiple, the terminal needs to select the most suitable target brightness to signal level curve. For example, if the brightness setting parameter of the terminal is 600 nits, then among the curves of 200 nits, 300 nits, 500 nits, and 1000 nits, the terminal will select the curve of 500 nits and set it as the target brightness to signal level curve.

[0142] Of course, if the server sets parameters for the brightness of the terminal, for example, 600 nits, calculates a target brightness versus signal level curve adapted to the terminal and sends it to the terminal, the terminal only needs to be set to the target brightness versus signal level curve.

[0143] In the above-mentioned display control method for restoring the production effect of the terminal, setting the target brightness versus signal level curve based on the display control instruction includes: determining whether the terminal has a preset brightness versus signal level curve; and, in response to the existence of the preset brightness versus signal level curve, adjusting the preset brightness versus signal level curve to the target brightness versus signal level curve.

[0144] In the above-mentioned display control method for restoring the production effect of the terminal, adjusting the preset brightness versus signal level curve to the target brightness versus signal level curve includes: inversely transforming the preset brightness versus signal level curve to obtain the initial correspondence between the signal level and the brightness of the current display device; and adjusting the initial correspondence between the signal level and the brightness of the current display device to the target brightness versus signal level curve.

[0145] In the above-mentioned display control method for restoring production effects of a terminal, setting the target brightness versus signal level curve based on the display control instruction includes: directly setting the target brightness versus signal level curve for the terminal when the terminal leaves the factory.

[0146] That is, as described above, setting the target brightness versus signal level curve of the display device may also include two cases. In one case, if the display device has a preset initial brightness versus signal level curve, it can be adjusted to the target brightness versus signal level curve by, for example, reverse conversion. In another case, if the display device has a brightness versus signal level curve set before leaving the factory, it can be directly set to the target brightness versus signal level curve.

[0147] In the above-mentioned display control method for restoring the production effect of the terminal, after setting the target brightness versus signal level curve based on the display control instruction, it further includes: determining whether the display content is in a predetermined format; in response to the display content being in a predetermined format, calling the target brightness versus signal level curve; and displaying the display content based on the target brightness versus signal level curve.

[0148] That is to say, after completing the setting of the target brightness versus signal level curve, if it is determined that the content to be displayed by the terminal is in a predetermined format, for example, an SDR format movie or an HDR format movie, then the target brightness versus signal level curve will be called, and the display content will be displayed based on the target brightness versus signal level curve.

[0149] In addition, the target brightness versus signal level curve may not be pre-set, but during the process of displaying the display content on the terminal, once it is determined that the display content is in a predetermined format, a display control instruction containing the target brightness versus signal level curve is received from the server side and set to the target brightness versus signal level curve, thereby displaying the display content based on the target brightness versus signal level curve.

[0150] Therefore, in the above-mentioned display control method for restoring the production effect of the terminal, receiving the display control instruction includes: determining whether the display content is in a predetermined format; and, in response to the display content being in the predetermined format, receiving the display control instruction from the server.

[0151] Here, those skilled in the art can understand that other details of the display control method for restoring the production effect of the terminal according to the third embodiment of the present application are exactly the same as the corresponding details of the display control method for restoring the production effect according to the first embodiment of the present application and the display control method for restoring the production effect of the server according to the second embodiment of the present application, so in order to avoid redundancy, they will not be repeated.

[0152] Therefore, the display control method for restoring the production effect according to the first to third embodiments of the present application can restore the screen constructed by the producer of the display content on various terminal devices, so that the user can obtain a good audio-visual experience.

[0156] In one example, in the above-mentioned display control device 400 for restoring the production effect, the reference benchmark parameter is the production review brightness of the display content when the final production is completed; and the reference display parameter is the brightness setting parameter of the current display device that displays the display content.

[0161] In one example, in the above-mentioned display control device 400 for restoring the production effect, the display parameter adjustment unit 330 is used to: determine a third brightness-to-signal level curve corresponding to the first brightness-to-signal level curve under the brightness setting parameters based on the first brightness-to-signal level curve; and adjust the second brightness-to-signal level curve of the current display device to the third brightness-to-signal level curve.

[0162] In one example, in the above-mentioned display control device 400 for restoring the production effect, the display parameter adjustment unit 430 adjusts the second brightness-to-signal level curve of the current display device to the third brightness-to-signal level curve, including: inversely transforming the second brightness-to-signal level curve to obtain the initial correspondence between the signal level and the brightness of the current display device; and adjusting the initial correspondence between the signal level and the brightness of the current display device to the third brightness-to-signal level curve.

[0163] In one example, in the above-mentioned display control device 400 for restoring the production effect, the display parameter adjustment unit 430 is used to: adjust other display parameters in the current display parameters based on the reference display parameters in the current display parameters, the reference benchmark parameters in the production benchmark parameters, and the environmental parameters of the current display device that displays the display content.

[0164] In one example, in the display control device 400 for restoring a production effect, the environmental parameter includes at least one of ambient brightness and ambient loudness.

[0165] Here, those skilled in the art can understand that the specific functions and operations of the various units and modules in the display control device 400 for restoring the production effect have been described in the above reference. Figures 1 to 5 The display control method for restoring the production effect is described in detail, and therefore, its repeated description will be omitted.

[0166] As described above, the display control device 400 for restoring the production effect according to the embodiment of the present application can be implemented in various terminal devices, such as a server of a video service provider, or a user device with a video playback application installed. In one example, the device 400 according to the embodiment of the present application can be integrated into the terminal device as a software module and / or a hardware module. For example, the device 400 can be a software module in the operating system of the terminal device, or it can be an application developed for the terminal device; of course, the device 400 can also be one of the many hardware modules of the terminal device.

[0167] Alternatively, in another example, the display control apparatus 400 for restoring the production effect and the terminal device may also be separate devices, and the apparatus 400 may be connected to the terminal device via a wired and / or wireless network, and transmit interactive information in accordance with an agreed data format.

[0168] Fig. 9 The figure illustrates a block diagram of a display control device for restoring production effects on a server side according to a second embodiment of the present application.

[0169] like Fig. 9 As shown, according to the second embodiment of the present application, a display control device 500 for restoring a production effect on the server side includes: a production parameter determination unit 510, used to determine the production review brightness of the display content when the final production is completed and its corresponding production brightness versus signal level curve; a target parameter calculation unit 520, used to calculate a target brightness versus signal level curve at a target display brightness based on the production brightness versus signal level curve; and a control instruction sending unit 530, used to send a display control instruction, wherein the display control instruction is used to control a display device that displays the display content to be set to the target brightness versus signal level curve.

[0174] Fig.10The diagram illustrates a block diagram of a display control device for restoring a production effect of a terminal according to a third embodiment of the present application.

[0175] like Fig.10 As shown, according to the third embodiment of the present application, a display control device 600 for restoring a production effect of a terminal includes: a control instruction receiving unit 610, used to receive a display control instruction, wherein the display control instruction is used to instruct the terminal displaying the display content to be set to a target brightness versus signal level curve, wherein the target brightness versus signal level curve is a target brightness versus signal level curve at a target display brightness, and is calculated based on the production brightness versus signal level curve, wherein the production brightness versus signal level curve is a brightness versus signal level curve when the final production of the display content is completed and corresponds to the production review brightness; and a display parameter setting unit 620, used to set the target brightness versus signal level curve based on the display control instruction.

[0176] In one example, in the display control device 600 for restoring production effects of a terminal, the target display brightness is one or more preset target display brightnesses.

[0177] In one example, in the above-mentioned display control device 600 for restoring the production effect of the terminal, the display parameter setting unit 620 is used to: determine the number of the preset target display brightnesses; and, in response to determining that the number of the preset target display brightnesses is one, set the terminal to a preset target brightness versus signal level curve.
