Detailed Description

Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein.

Summary of the application

As described above, in order to improve the internet viewing experience of the user, the following three approaches are mainly used.

Firstly, the display quality of the content itself is improved by elaborating the content medium; secondly, transcoding the content by an excellent transcoding technology so as to reduce the loss of content quality in the transcoding process as much as possible; and, high-quality video and audio playback equipment is adopted as much as possible.

However, even if all the above conditions are satisfied, in many cases, it is still found that the effect of 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 obtain the same viewing experience as watching the movie in a cinema.

The inventor of the present application has studied to find that, although some optimization has been performed for the display content in terms of the current terminal player, none of the optimization considers the factors of the display content at the time of the final production completion. For example, after a film is produced, it is eventually necessary to review the film-breaking effect of the entire film by a director who is typically provided with specific parameter settings, after film-cutting, aesthetic toning, and other post-adjustment.

In view of the above technical problems, the basic idea of the present application is to adjust other display parameters based on a production reference parameter of display content and a key parameter in a current display parameter, so that a presentation effect of the display content is adjusted to be the same as a display effect based on the production reference parameter, thereby restoring the production effect.

Specifically, the display control method, the display control device and the electronic device for restoring the production effect first determine a production benchmark parameter of the display content, then acquire a current display parameter of the display content, and finally adjust other display parameters in the current display parameter based on a reference display parameter in the current display parameter and a reference benchmark parameter in the production benchmark parameter, so that the display content is presented with the display effect according to the production benchmark parameter. Therefore, the effect of content production can be restored and displayed to the user, and the audio-visual experience of the user is improved.

Here, those skilled in the art will understand that the display content in the scheme of the present application is not limited to movies played through a video application, but also includes various types of display content displayed through other display devices. For example, the display content may be a tv series or other program played through a smart phone, tablet, or tv, and this application is not intended to limit this in any way.

Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.

Exemplary method

[ first embodiment ] A method for manufacturing a semiconductor device

As shown in fig. 1, a display control method for restoring a production effect according to a first embodiment of the present application includes: s110, determining a production reference parameter of the display content; s120, acquiring 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 standard parameters in the production standard parameters, so that the display content is presented with the display effect according to the production standard parameters.

In step S110, a production reference parameter of the display content is determined. As mentioned above, after the display content such as a movie is finished being filmed, other post-processing such as cut-and-crop, aesthetic toning, etc. is required, which is usually done by specialized post-production personnel. After the post-production is completed, the film is finally viewed and reviewed by the director of the film or the producer of other types of programs. Therefore, in order to restore the production effect, in the embodiment of the present application, it is necessary to determine production reference parameters at the time of review after the completion of production of the display content.

One of the main parameters of the production reference is the brightness of the display device that displays the display content at the time of review, which is particularly evident in movie production. Since, in general, movies are viewed by the audience in theaters, the theatre environment is usually dark and the director, in order to get a realistic play effect, also usually views the movie filmed on a particular device.

Currently, devices for director to view films are largely classified into two types, Standard Dynamic Range (SDR) and High Dynamic Range (HDR), and the brightness of these two types of display devices is not the same. Specifically, the luminance of the SDR display device is 100 nits, while the luminance of the HDR display device is 1000 nits. Therefore, the production audit brightness of the display content at the time of final production completion can be determined according to the format of the display content.

That is, in the display control method for restoring a production effect according to the embodiment of the present application, determining the production reference parameter of the display content 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 a production review luminance 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 a production review brightness of the display content is 1000 nits.

Here, as will be understood by those skilled in the art, the production reference parameter in the embodiment 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 at the time of final production.

In step S120, a current display parameter of the display content is acquired. As described above, when considering the brightness of the display device, the director watches film-cut devices typically 100 nits or 1000 nits, and the terminal devices used by the user for watching movies, such as smart phones, tablet computers, televisions, etc., typically have different brightness depending on other devices.

Specifically, the display brightness of the current smart phone is 200 nits to 1000 nits, the display brightness of the tablet computer is 200 nits to 500 nits, and the display brightness of the household television and the display is 150 nits to 1000 nits.

In addition, in order to obtain accurate display parameters as much as possible in consideration of different terminal devices used by users at present, in the embodiment of the present application, a database containing brightness parameters and other display parameters is established in advance according to device model parameters of the terminal devices, and then current display parameters are obtained by querying the database.

Therefore, in the display control method for restoring a production effect according to the embodiment of the present application, the reference parameter is production verification luminance of the display content at the time of final production completion; and the reference display parameter is a brightness setting parameter of a current display device displaying the display content.

As described above, although the current main production review brightness is 100 nit or 1000 nit depending on the format of the display content, other devices may have different brightness, such as 200 nit, and the embodiment of the present application is not intended to limit this.

Here, the brightness setting parameter refers to a maximum value of the brightness setting of the current display apparatus. Taking the brightness setting parameter as 200 nits as an example, it is indicated 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, the brightness setting parameter is fixed for the same model of device, and thus, the brightness setting parameter can be obtained by the device model parameter of the terminal device.

In addition, the terminal device has a luminance versus signal level curve, which is a photoelectric conversion type curve, for representing a relationship between luminance and signal level, corresponding to the luminance setting parameter. Since the magnitude of the signal level is directly related to the human eye's perception of the screen, different display modes, e.g., vivid color mode, soft color mode, etc., perceived by the human eye can be set by adjusting the luminance versus signal level curve.

It should be noted that, in the embodiment of the present application, the luminance versus signal level curve corresponding to the luminance setting parameter of the current display device displaying the display content is not related to the backlight luminance of the terminal device such as a smart phone, i.e. the screen luminance usually adjusted by the user, but also depends on the characteristics of the display panel, such as the light transmission characteristics of the liquid crystal layer. When the user adjusts the brightness on the terminal device, it essentially moves on such a brightness versus signal level curve.

Therefore, in the display control method for restoring a production effect according to the embodiment of the present application, the reference parameter further includes a first luminance versus signal level curve corresponding to the production audit luminance of the display content at the time of final production completion; and the reference display parameter further comprises a second brightness-to-signal level curve corresponding to the brightness setting parameter of the current display device.

Moreover, such luminance vs. signal level curves are usually not directly available from the terminal device, or even from the manufacturer of the terminal device, but need to be measured by a special luminance measuring tool under certain circumstances. Therefore, for various display devices at present, it is necessary to test the luminance versus signal level curves and build a database in advance.

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

Of course, those skilled in the art can also understand that in the embodiment of the present application, the display parameter of the display device is not limited to the brightness, and the reference display parameter may also be other parameters of the display device depending on the production benchmark parameter obtained in step S110.

In step S130, adjusting other display parameters in the current display parameters based on the reference display parameters in the current display parameters and the reference standard parameters in the production standard parameters, so that the display content is presented with a display effect according to the production standard parameters.

Specifically, when the reference display parameter and the reference base parameter are display luminance of the display device, the other display parameter includes at least one of contrast, chromaticity, color difference, and color shift. That is to say, for the difference of the display brightness, in the embodiment of the present application, only one other display parameter may be adjusted, or a plurality of other display parameters may be adjusted at the same time, so that the display content is presented with the display effect according to the production reference parameter.

Fig. 2 illustrates a schematic diagram of a relationship curve between different display parameters according to an embodiment of the application. As shown in fig. 2, the horizontal axis represents the value of parameter 1, which may be, for example, a luminance parameter in nits, or a chrominance parameter in chrominance values in the range of 0 to 255, or other parameters, and the vertical axis represents the value of parameter 2. In the simplest case, parameter 1 and parameter 2 exhibit a linear relationship, as shown by curve a in fig. 2, but in most cases, parameter 1 and parameter 2 exhibit a non-linear relationship, as shown by curves b and c in fig. 2.

Fig. 3 illustrates a schematic diagram of a first example of parameter adjustment according to an embodiment of the application. As shown in fig. 3, for example, if the display luminance (horizontal axis in the figure) is linearly related to the contrast (vertical axis in the figure). In the case of the production audit brightness of 100 nits, the value of the contrast ratio is P1, and then, in the case of the current brightness of the current display device of the display content of 400 nits, the value of the contrast ratio is correspondingly adjusted to P2, so that the display effect of the display content is consistent with the effect of the production audit brightness according to 100 nits.

Fig. 4 illustrates a schematic diagram of a second example of parameter adjustment according to an embodiment of the application. As shown in fig. 4, for example, if the display luminance (horizontal axis in the figure) is in a non-linear relationship with the chrominance (at least one of R, G, B, for example) (vertical axis in the figure). In the case of the production audit brightness of 100 nits, the value of the contrast ratio is V1, and then, in the case of the current brightness of the current display device of the display content of 400 nits, the value of the contrast ratio is correspondingly adjusted to V2, so that the display effect of the display content is consistent with the effect of the production audit brightness according to 100 nits.

Fig. 5 illustrates a diagram of luminance versus signal level curve adjustment according to an embodiment of the present application. Fig. 5 (a) shows a first luminance versus signal level curve of the display content obtained at the time of final production completion. Here, the horizontal axis of the graph represents luminance, and as described above, in the SDR format, the maximum is 100 nits, and the vertical axis represents a signal level, which ranges from 0 to 255. Therefore, when the maximum luminance is 100 nits, the signal level is 255.

Fig. 5 (B) shows a third luminance versus signal level curve corresponding to the first luminance versus signal level curve under another luminance, i.e., a luminance setting parameter of the current display device. Here, as will be understood by those skilled in the art, the luminance versus signal level curve corresponding to a luminance versus signal level curve at a certain maximum luminance at another maximum luminance can be calculated by the existing algorithm. That is, under the third luminance versus signal level curve shown in fig. 5 (B), the display effect of the display content viewed by the user through the current display apparatus is the same as that of the display content at the time of the final production completion. 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 reviewing the movie last is 100 nits, then when the playback device used by the director has a first luminance versus signal level curve corresponding to 100 nits and the terminal device used by the user has a third luminance versus signal level curve corresponding to the first luminance versus signal level curve at 300 nits, the user can see the exactly same effect on the terminal as the director would see on the playback device, that is, the truest effect that the director would like to present when filming the movie is completely restored.

However, as described above, for a terminal device actually used by a user, it is possible to adjust a luminance versus signal level curve to different curves of various shapes depending on a terminal device manufacturer to achieve a specific visual effect. For example, when the brightness is adjusted to be relatively flat to the signal level curve, the displayed visual effect is relatively soft, and when the brightness is adjusted to be relatively wavy to the signal level curve, the displayed visual effect is relatively bright in color.

Therefore, in order to exhibit the same effect as that of the display contents at the time of the final production completion, the second luminance versus signal level curve originally existing in the current display apparatus used by the user as shown in (C) of fig. 5 is adjusted to the third luminance versus signal level curve as shown in (B) of fig. 5.

That is, in the display control method for restoring a 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 parameters in the production reference parameters includes: determining a third luminance versus signal level curve corresponding to the first luminance versus signal level curve under the luminance setting parameter based on the first luminance versus signal level curve; and adjusting a second luminance versus signal level curve of the current display device to the third luminance versus signal level curve.

Here, the adjustment of the luminance versus signal level curve may be based on a current luminance versus signal level curve, i.e., the second luminance versus signal level curve as described above, and a target luminance versus signal level curve, i.e., the reverse adjustment of the third luminance versus signal level curve as described above. The luminance versus signal level curve may also be set to a target luminance versus signal level curve directly at the time of shipment of the display device. That is, in the embodiment of the present application, adjusting the luminance versus signal level curve of the current display device includes setting a third luminance versus signal level curve corresponding to the first luminance versus signal level curve under the luminance setting parameter when the current display device is shipped from a factory.

When the signal level curve of the brightness of the current display device is inversely adjusted, the signal level curve of the brightness needs to be inversely transformed to obtain an initial corresponding relationship, for example, a linear relationship, between the signal level and the brightness of the current display device. As described above, for various terminal devices, adjustment is performed on the basis of the initial correspondence of the signal level and the luminance, for example, if color contrast needs to be enhanced, the linear relationship curve of the signal level and the luminance is pulled up so that the signal level curve is steeper in the case of low luminance and gentler in the case of high luminance. Thus, after the luminance versus signal level curve of the current display device is restored to the initial curve, the initial curve may be adjusted to a desired target luminance versus signal level curve.

Therefore, in the display control method for restoring a production effect according to an embodiment of the present application, adjusting the second luminance versus signal level curve of the current display device to the third luminance versus signal level curve includes: inversely transforming the signal level curve of the second brightness to obtain an initial corresponding relation between the signal level and the brightness of the current display equipment; and adjusting the initial corresponding relation between the signal level and the brightness of the current display equipment to be the third brightness-to-signal level curve.

It should be emphasized that the adjustment of the luminance versus signal level curve in the embodiment of the present application is different from the adjustment of the luminance in the existing various terminal devices. As described above, the adjustment of the luminance in the existing terminal device is actually to obtain the signal level corresponding to the vertical axis by adjusting the luminance corresponding to the horizontal axis of the curve on the fixed luminance versus signal level curve, thereby presenting different feelings to the user. Therefore, if the luminance versus signal level curve of the current display device of the user under the luminance setting parameter is not adjusted, the effect that the display content is to show when the production is completed, for example, when the film is finally filmed and audited by the director, cannot be restored, and thus a completely real viewing experience cannot be obtained.

In addition, in the display control method for restoring a production effect according to the embodiment of the present application, in addition to considering a difference between a display parameter of a current display apparatus displaying the display content and a production reference parameter, an influence of an environmental factor of the current display apparatus on the display effect may be further considered.

That is to say, in the display control method for restoring a 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 standard parameters in the production standard parameters includes: and adjusting other display parameters in the current display parameters based on the reference display parameters in the current display parameters, the reference parameters in the production reference parameters and the environment parameters of the current display equipment displaying the display contents.

In particular, the ambient parameters may include ambient brightness, ambient loudness, and other ambient factors. Aiming at the brightness factor of the surrounding environment, the scene rendering can be correspondingly carried out on the display content aiming at different scenes, such as an outdoor scene, an office scene, a subway scene and the like, and various display parameters are intelligently adapted, so that the presentation effect and the production effect of the display content are consistent. In addition, intelligent sound field adaptation can be performed for the surrounding loudness factors, including loudness normalization, automatic human voice recognition, dialogue protection, and the like, for example.

[ second embodiment ]

As shown in fig. 6, a display control method for restoring a production effect according to a second embodiment of the present application includes: s210, determining the production auditing brightness of the display content when the final production is finished and a corresponding production brightness-signal level curve; s220, calculating a target brightness-signal level curve under target display brightness based on the manufactured brightness-signal level curve; and S230, sending a display control instruction for controlling to set a display device displaying the display content to the target brightness versus signal level curve.

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

Then, in step S220, a luminance versus signal level curve at the target display luminance is calculated based on the luminance 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, it can be understood by those skilled in the art that in the present embodiment, the target display brightness is a preset general display brightness, for example, 300 nits regardless of the display device, while in other embodiments, for example, in the previously described embodiments, the target display brightness may also be a brightness setting parameter determined for the current display device, for example, 200 nits, 500 nits, 1000 nits, and the like depending on different devices.

Finally, in step S230, a display control instruction for controlling a display device displaying the display content is sent, so that the display device is set to the target luminance versus signal level curve, i.e., the target luminance versus signal level curve at 300 nits as described above.

That is, in the second embodiment of the present application, after determining the production reference parameter of the display content, specifically, the production verification luminance and the corresponding production luminance versus signal level curve of the display content at the time of final production, the target luminance versus signal level curve may be determined directly from the production luminance versus signal level curve. For example, the production luminance versus signal level curve corresponds to a luminance of 100 nits, while the target luminance versus signal level curve corresponds to one or more luminances, such as 200 nits, 300 nits, 500 nits, 1000 nits, and so on. Then, when the display content is displayed with a display device, the luminance versus signal level curve of the display device is adjusted to a default one of the target luminance versus signal level curves, e.g., 300 nits, regardless of the display parameters of the display device itself. In this way, although the target luminance versus signal level curve is not optimized for the display content for different display devices, the degree of restitution of the display content may still be improved over the original luminance versus signal level curve of the display device.

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

Here, as can be understood by those skilled in the art, other details of the display control method for the server-side restoring production effect according to the second embodiment of the present application are completely the same as those of the display control method for the server-side restoring production effect according to the first embodiment of the present application, and therefore are not described again to avoid redundancy.

[ third embodiment ]

As shown in fig. 7, a display control method for a reduction production effect of a terminal according to a third embodiment of the present application includes: s310, receiving a display control instruction, wherein the display control instruction is used for indicating a terminal displaying display content to set a target brightness-to-signal level curve, the target brightness-to-signal level curve is a target brightness-to-signal level curve under target display brightness and is calculated based on the manufactured brightness-to-signal level curve, and the manufactured brightness-to-signal level curve is a brightness-to-signal level curve when the final manufacturing of the display content is completed and corresponds to manufactured auditing brightness; and S320, setting the target brightness-to-signal level curve based on the display control instruction.

That is, because, as described above, when the server side calculates the target luminance versus signal level curves, it is possible to calculate one or more preset target luminance versus signal level curves, e.g., 200 nit, 300 nit, 500 nit, 1000 nit, corresponding to one or more target display luminances, and transmit these target luminance versus signal level curves to the terminal and store them in a curve library preset in the terminal, e.g., a predetermined curve library of a video playback application. In this case, when the terminal sets a target luminance versus 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 sets the entry to the luminance vs. signal level curve. Whereas if the number of curves is multiple, the terminal needs to select the most appropriate target luminance versus signal level curve. For example, if the brightness setting parameter of the terminal is 600 nits, the terminal will select the 500 nits curve among the 200 nits, 300 nits, 500 nits, 1000 nits curves and set the entry target brightness versus signal level curve.

Of course, if the server side calculates a target luminance versus signal level curve adapted to the terminal for the luminance setting parameter of the terminal, for example, 600 nits, and sends the target luminance versus signal level curve to the terminal, the terminal only needs to set the target luminance versus signal level curve of the entry.

That is, as described above, setting the target luminance versus signal level curve of the display device may also include two cases. One case is that if the display device has a preset initial luminance versus signal level curve, it can be adjusted to a target luminance versus signal level curve by means of, for example, inverse transformation. Alternatively, if the display device is set to the target luminance versus signal level curve directly before the luminance versus signal level curve is set at the time of factory shipment.

That is, after the setting of the target luminance versus signal level curve is completed, if it is determined that the content to be displayed by the terminal is a predetermined format, for example, an SDR format movie or an HDR format movie, the target luminance versus signal level curve is called and the display content is displayed based on the target luminance versus signal level curve.

In addition, the target brightness versus signal level curve may not be preset, but in the process of displaying the display content by the terminal, once the display content is determined to be in a predetermined format, a display control instruction including the target brightness versus signal level curve is received from the server side and is set as the target brightness versus signal level curve, so that the display content is displayed based on the target brightness versus signal level curve.

Therefore, in the above display control method for the restoration creation effect of the terminal, receiving the display control instruction includes: determining whether the display content is in a predetermined format; and responding to the display content in a preset format, and receiving the display control instruction from the server side.

Here, it can be understood by those skilled in the art that other details of the display control method for the effect of restoring production of the terminal according to the third embodiment of the present application are completely the same as those of the display control method for the effect of restoring production of the first embodiment of the present application and the display control method for the effect of restoring production of the server according to the second embodiment of the present application, and therefore, the details are not repeated to avoid redundancy.

Therefore, the display control method for restoring a production effect according to the first to third embodiments of the present application can enable a screen constructed by a producer of display content to be restored on various terminal devices, thereby enabling a user to obtain a good viewing experience.
