All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The display control method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.
The display control method provided by the embodiment of the application can be applied to a scene that a user shares a multimedia file through the display control device.
Assuming that the user a wants to share a picture with the user B, in the related art, the user a may first take a picture 1 to be shared through the display control device 1, and perform editing input on the picture 1 to trigger the display control device 1 to control the picture 1 to enter an editable state, so that the user a may adjust display parameters of the picture 1, where the display parameters may include saturation, hue, brightness, and the like, and perform storage input on the adjusted picture 1, and then the user a may send the picture 1 to the display control device 2 of the user B through the display control device 1, so that the user B may perform click input on the adjusted picture 1 to enable the display control device 2 to display the adjusted picture 1, and thus the user B may view the adjusted picture 1. However, since the hardware devices of the display control apparatus 1, such as the display screen type of the display screen, may be different from the display screen type of the display screen of the display control apparatus 2, when displaying the adjusted picture 1, the display color of the display control apparatus 2 may be different from the display color of the display control apparatus 1, and thus, a situation that the display control apparatus 2 displays the adjusted picture 1 with color distortion may occur.
However, in the embodiment of the present application, after the user a performs storage input on the adjusted picture 1, the display control apparatus 1 may store the adjusted display parameters into an International Color Consortium (ICC) color profile of the picture 1, where the picture 1 is an unadjusted picture, and then the display control apparatus 1 may obtain parameters of the display screen of the display control apparatus 1, which may be a color gamut, and store the parameters into the ICC color profile of the picture 1, so that the user a may transmit the picture 1 to the display control apparatus 2 through the display control apparatus 1, so that the display control apparatus 2 may obtain the color gamut of the display screen of the display control apparatus 1 from the ICC color profile of the picture 1 in case of receiving the picture 1, and based on the color gamut of the display screen of the display control apparatus 1 and the color gamut of the display screen of the display control apparatus 2, and displaying the picture 1 on the display screen of the display control device 2 according to at least one of the color gamut of the display screen of the display control device 2, the display parameters of the display screen of the display control device 2 and the display parameters of the display content of the picture 1 after adjustment. Therefore, the situation that the display color of the display control device 2 is different from the display color of the display control device 1 when the picture 1 is displayed due to the fact that the display screen type of the display screen of the display control device 1 is different from the display screen type of the display screen of the display control device 2 can be avoided, and the situation that the picture 1 is displayed by the display control device 2 and is distorted in color can be avoided.
Fig. 1 shows a flowchart of a display control method according to an embodiment of the present application. As shown in fig. 1, the display control method provided in the embodiment of the present application may include steps 101 to 103 described below.
Step 101, under the condition of receiving a target multimedia file sent by a second display control device, a first display control device obtains a first type parameter of a first display screen of the second display control device from a header file of the target multimedia file.
Optionally, in this embodiment of the application, in a process that the user 1 uses the second display control device, the user 1 may open a shooting type application program of the second display control device, so that the second display control device may display a shooting preview interface, and perform a shooting input in the shooting preview interface, so that the second display control device may collect a target multimedia file through a camera of the second display control device, and update the shooting preview interface to a first interface, where the first interface includes the target multimedia file, and then the user 1 may perform a storage input on the target multimedia file, so that the second display control device may store the target multimedia file, and acquire a first type parameter of the first display screen, so that the second display control device may store the first type parameter into a header file of the target multimedia file, i.e. into the ICC color profile. In this way, the user 1 may trigger the second display control device to select the target multimedia file, and send the target multimedia file to the first display control device, so that the first display control device may obtain the first type of parameter of the first display screen.
Further optionally, in this embodiment of the application, the shooting input may be: a user's press input to the first display screen, e.g., a user's click input to a "shoot" control in a shoot preview interface; alternatively, the user inputs a press input to a physical key of the second display control device, for example, a long press input to the physical key by the user. The shooting input may be input in other forms, and the embodiment of the present application is not limited to this.
Further optionally, in this embodiment of the application, the storage input may be: a user pressing input to the first display screen, e.g., a user clicking input to a "save" control in the first interface. It should be noted that the storage input may also be other forms of input, and the embodiment of the present application is not limited to this.
Optionally, in this embodiment of the application, the target multimedia file may specifically be any one of the following: images, videos.
In this embodiment of the application, the first type parameter is used to indicate a display screen type of the first display screen.
Optionally, in this embodiment of the application, the display screen type of the first display screen may be any of the following: a Cathode Ray Tube (CRT) type, an organic light-emitting diode (OLED) type, a Liquid Crystal Display (LCD) type, and the like.
Optionally, in this embodiment of the application, the first type of parameter may specifically be: the color gamut of the first display screen, for example, the first color gamut in the embodiments described below. Wherein, the color gamut of the first display screen can be any one of the following: srgb (standard greenblue) color gamut, ntsc (national television standards committee) color gamut, Adobe RGB color gamut, DisplayP3 color gamut, DCI-P3 color gamut, and the like.
Optionally, in this embodiment of the present application, the first display control apparatus may detect a header file, that is, an ICC color profile, in the target multimedia file to obtain the first type of parameters.
And 102, the first display control device adjusts the target parameters based on the first type of parameters and the second type of parameters of the second display screen of the first display control device.
Optionally, in this embodiment of the application, after the first display control device acquires the first type of parameter, the first display control device may detect the second display screen to acquire the second type of parameter, so that the first display control device may adjust the target parameter based on the first type of parameter and the second type of parameter.
In this embodiment of the application, the second type of parameter is used to indicate a display screen type of the second display screen.
Optionally, in this embodiment of the application, the display screen type of the second display screen may be any of the following: a Cathode Ray Tube (CRT) type, an organic light-emitting diode (OLED) type, a Liquid Crystal Display (LCD) type, and the like.
Further optionally, in this embodiment of the application, the display screen type of the second display screen may be the same as or different from the display screen type of the first display screen.
Optionally, in this embodiment of the application, the second type of parameter may specifically be: the color gamut of the second display screen, for example, the second color gamut in the embodiments described below. Wherein, the color gamut of the second display screen can be any one of the following: srgb (standard greenblue) color gamut, ntsc (national television standards committee) color gamut, Adobe RGB color gamut, DisplayP3 color gamut, DCI-P3 color gamut, and the like.
Further optionally, in this embodiment of the application, the second type parameter may be the same as or different from the first type parameter. It will be appreciated that the gamut of the second display screen may be the same or different from the gamut of the first display screen.
In an embodiment of the present application, the target parameter includes at least one of: the second type of parameters, the display parameters of the second display screen and the display parameters of the target multimedia file.
Optionally, in this embodiment of the application, the display parameter may include at least one of the following: saturation, hue, brightness, etc.
Optionally, in this embodiment of the application, the first display control device may determine the target parameter according to whether the first type of parameter and the second type of parameter are matched, and then adjust the target parameter.
Further optionally, in this embodiment of the application, in a case that the first type of parameter matches the second type of parameter, the first display control device may adjust at least one of a display parameter of the second display screen and a display parameter of the target multimedia file.
It should be noted that "the first type parameter and the second type parameter match" may be understood as: the first type of parameters and the second type of parameters are the same; or the difference value between the first type parameter and the second type parameter is in a preset range.
Exemplarily, assuming that the first type parameter is a color gamut of a first display screen, the color gamut of the first display screen is 105% NTSC, the second type parameter is a color gamut of a second display screen, the color gamut of the second display screen is 96% NTSC, and a preset range is-10% NTSC, because a difference value between the first type parameter and the second type parameter is 9% NTSC, and the 9% NTSC is within-10% NTSC, the difference value between the first type parameter and the second type parameter is within the preset range, i.e., the first type parameter and the second type parameter are matched.
It should be noted that NTSC refers to the color gamut introduced by the national television systems committee in 1953. The color gamut of the above-described display screen may be depicted using the 1931CIE x-y chromaticity diagram published by the international commission on illumination (international commission on lighting) or the "CIE". The NTSC standard defines a triangle on the CIE x-y chromaticity diagram, and thus the color gamut can be expressed as a percentage of the area of the triangle defined by the NTSC standard. Thus, for example, if the first color gamut is 9% higher than the second color gamut, NTSC, the area on the CIE x-y chromaticity diagram of the light output of the display screen for the second display control device may be considered to be 9% higher than the area on the CIE x-y chromaticity diagram of the light output of the display screen for the first display control device.
In this embodiment of the application, if the first type of parameter and the second type of parameter are matched, it may be considered that the display screen type of the first display screen is the same as the display screen type of the second display screen, that is, the hardware level is at the same level, and therefore, the first display control device may adjust at least one of the display parameter of the second display screen and the display parameter of the target multimedia file, so that when the target multimedia file is displayed, the display color of the target multimedia file displayed by the first display control device is the same as or similar to the display color of the target multimedia file displayed by the second display control device.
Further optionally, in this embodiment of the application, in a case that the first type parameter and the second type parameter do not match, the first display control device may adjust at least one of the second type parameter and a display parameter of the second display screen.
It should be noted that the above "the first type parameter and the second type parameter do not match" can be understood as follows: the first type of parameters and the second type of parameters are different; or the difference value between the first type parameter and the second type parameter is out of the preset range.
Exemplarily, assuming that the first type parameter is a color gamut of a first display screen, the color gamut of the first display screen is 115% NTSC, the second type parameter is a color gamut of a second display screen, the color gamut of the second display screen is 85% NTSC, and a preset range is-10% NTSC, because a difference value between the first type parameter and the second type parameter is 30% NTSC, and the 30% NTSC is outside the-10% NTSC, the difference value between the first type parameter and the second type parameter is outside the preset range, i.e., the first type parameter and the second type parameter are not matched.
In this embodiment of the application, if the first type of parameter and the second type of parameter are not matched, it may be considered that the display screen type of the first display screen is different from the display screen type of the second display screen, that is, the hardware level has a large difference, and therefore, the first display control device may adjust at least one of the second type of parameter and the display parameter of the second display screen, so that when the target multimedia file is displayed, the display color of the target multimedia file displayed by the first display control device is the same as or similar to the display color of the target multimedia file displayed by the second display control device.
Optionally, in this embodiment of the application, the first display control device may adjust the second type of parameter to another parameter, for example, the first type of parameter, so as to adjust the second type of parameter.
Further alternatively, in this embodiment of the application, the first display control device may adopt a preset algorithm, for example, a first preset algorithm in the following embodiments, to adjust the second type of parameter to other parameters.
Optionally, in this embodiment of the application, the first display control device may increase a parameter value of the display parameter of the second display screen according to one preset value, or may decrease a parameter value of the display parameter of the second display screen according to another preset value.
Optionally, in this embodiment of the application, the first display control device may obtain a parameter adjustment value from the head file, for example, a target parameter adjustment value in the following embodiments, and adjust a parameter value of a display parameter of the target multimedia file according to the parameter adjustment value; alternatively, the first display control device may turn down or turn up the parameter value of the display parameter of the target multimedia file according to a preset parameter adjustment value.
Further optionally, in this embodiment of the application, the parameter adjustment value may specifically be: the second display control means is obtained in accordance with the editing input of the user 1 to the target multimedia file.
Further alternatively, in this embodiment of the application, the first display control device may adopt a preset algorithm, for example, a second preset algorithm in the following embodiments, to reduce the parameter value of the display parameter of the target multimedia file.
And 103, displaying the target multimedia file in the second display screen by the first display control device according to the adjusted target parameter.
It can be understood that the display color of the target multimedia file displayed in the second display screen by the first display control device is the same as or similar to the display color of the target multimedia file displayed in the first display screen by the second display control device.
In the embodiment of the application, in the case that the first display control device receives the target multimedia file sent by the second display control device, the first display control device can display the identifier of the target multimedia file, e.g., a thumbnail, so that the user can enter an identification of the target multimedia file, so that the first display control device can acquire the first type parameters of the display screen of the second display control device from the header file of the target multimedia file, so that the first display control device can adjust at least one of the second type parameter of the second display screen, the display parameter of the second display screen and the display parameter of the target multimedia file according to the first type parameter of the first display screen and the second type parameter of the second display screen, so that when the target multimedia file is displayed, the display color of the first display control device is the same as or similar to the display color of the second display control device.
In the display control method provided in the embodiment of the present application, when a target multimedia file sent by a second display control device is received, a first display control device may obtain, from a header file of the target multimedia file, a first type of parameter for indicating a display screen type of a display screen of the second display control device, adjust a target parameter based on the first type of parameter and a second type of parameter for indicating the display screen type of the display screen of the first display control device, where the target parameter includes at least one of the second type of parameter, the display parameter of the second display screen, and the display parameter of the target multimedia file, and display the target multimedia file in the second display screen according to the adjusted target parameter. Since the first display control device can adjust at least one of the second type parameter, the display parameter of the display screen of the first display control device and the display parameter of the target multimedia file based on the first type parameter of the display screen of the second display control device sending the multimedia file and the second type parameter of the display screen of the first display control device, and display the multimedia file in the second display screen according to at least one of the adjusted second type parameter, the adjusted display parameter of the display screen of the first display control device and the adjusted display parameter of the target multimedia file instead of directly displaying the multimedia file, in case of receiving the multimedia file, it is possible to avoid that the display screen type of the display screen of the first display control device is different from the display screen type of the display screen of the second display control device, when the multimedia file is displayed, the display color of the first display control device is different from the display color of the second display control device, so that the situation that the first display control device displays the multimedia file and has color distortion can be avoided, and the accuracy of the first display control device in displaying the color of the multimedia file can be improved.
It can be understood that, after the first display control device sends or shares the target multimedia file, the first display control device can dynamically adjust the display content or adjust the parameters of the display screen, so that the user 2 of the first display control device can obtain the effect experience close to the consistency with the user 1, so that the original intention of the user 1 can be transmitted to the user 2, and the multimedia file can be expressed to the user 2 with the best effect, therefore, the adjustment of the multimedia file is more intelligent, and simultaneously, the method is convenient and efficient, and can accurately transmit and express information, so as to improve the use experience of the user.
In the following, how the first display control device adjusts the target parameter will be exemplified by taking as an example that the display screen type of the display screen of the second display control device is the same as the display screen type of the display screen of the first display control device, that is, the hardware levels of the two display screens are at the same level.
Alternatively, in this embodiment of the application, as shown in fig. 2 in combination with fig. 1, the step 102 may be specifically implemented by a step 102a described below.
102a, under the condition that the first type of parameters are matched with the second type of parameters, the first display control device adjusts the display parameters of the target multimedia file.
Further optionally, in this embodiment of the application, the first display control device may obtain a parameter adjustment value from the head file, and adjust a parameter value of a display parameter of the target multimedia file according to the parameter adjustment value.
In the embodiment of the application, under the condition that the display screen type of the display screen of the second display control device is the same as or similar to the display screen type of the display screen of the first display control device, the first display control device can firstly adjust the display parameters of the target multimedia file, then, the target multimedia file is displayed instead of directly displaying the target multimedia file, and the user is not required to store and adjust the display parameters of the target multimedia file and store the target multimedia file after adjusting the display parameters again, therefore, the first display control device can avoid color distortion when displaying the target multimedia file, and can also avoid repeatedly storing the target multimedia file with different display parameters, thus, the accuracy of displaying the color of the multimedia file by the first display control device can be improved, and meanwhile, the storage space of the first display control device is saved.
Optionally, in this embodiment of the present application, the first type of parameter includes: the first color gamut of the first display screen, the second type of parameter includes: a second color gamut of the second display screen. Specifically, referring to fig. 2, as shown in fig. 3, before the "adjusting the display parameter of the target multimedia file" in the step 102a, the display control method provided in the embodiment of the present application may further include the following step 201 and step 202, and the step 102a may be specifically realized by the following step 102a 1.
Step 201, under the condition that the difference value between the first color gamut and the second color gamut is within a preset range, the first display control device obtains a target coordinate range and a target parameter adjustment value of the target multimedia file from the header file.
Further optionally, in this embodiment of the application, after the second display control device stores the target multimedia file, the user 1 may perform an editing input on the target to the media file to trigger the second display control device to control the target multimedia file to be in an editable state, so that the user 1 may adjust a display parameter of an image area of the target multimedia file, where the image area of the target multimedia file may be a target image area in the following embodiments, and trigger the second display control device to acquire color feature information of the adjusted target multimedia file, so that the second display control device may determine a target coordinate range and an adjusted parameter value of the target image area according to the color feature information, where the adjusted parameter value is a target parameter adjustment value, and store the target coordinate range and the target parameter adjustment value into a header file of the target multimedia file, thus, the user 1 can input the target multimedia file so that the second display control device can transmit the target multimedia file to the first display control device, and thus, the first display control device can acquire the target coordinate range and the target parameter adjustment value.
It is understood that the target multimedia file is: the original multimedia file without adjusting the display parameters.
Further optionally, in this embodiment of the application, the target coordinate range may specifically be: the coordinate range in the coordinate system is preset.
It should be noted that the preset coordinate system may be: the first display control device takes a central point of a display screen of the first display control device as a coordinate origin, and takes straight lines where two central axes of the display screen are located as an X axis and a Y axis respectively to establish a plane rectangular coordinate system.
For example, the second display control device may determine the target coordinate range and the target parameter adjustment value using a neural network algorithm model according to the color feature information of the target multimedia file, where the neural network algorithm model is: the multimedia file is obtained by adopting a plurality of groups of corresponding relations for training in advance, wherein each group of corresponding relations are respectively color characteristic information, a coordinate range and a parameter adjustment value of a multimedia file.
Further illustratively, the second display control device may determine, from a plurality of sets of correspondences in the historical usage data of the user, color feature information of one multimedia file corresponding to the color feature information of the target multimedia file according to the color feature information of the target multimedia file, so that the second display control device may determine, as a target coordinate range and a target parameter adjustment value, one coordinate range and one parameter adjustment value from a set of correspondences corresponding to the color feature information of the one multimedia file.
Further alternatively, in this embodiment of the application, the first display control device may determine a difference value between the first color gamut and the second color gamut to determine whether the difference value is within a preset range.
In this embodiment, the target coordinate range is used to indicate at least one image area in an image corresponding to a target multimedia file, where the at least one image area is a target image area in the following embodiments; the target parameter adjustment value is used for adjusting the display parameter of the target multimedia file, namely, adjusting the parameter value of the display parameter of the target multimedia file to be larger or adjusting the parameter value of the display parameter of the target multimedia file to be smaller.
Further optionally, in this embodiment of the application, in a case that the target multimedia file is an image, the target coordinate range is used to indicate an image area in the image; in the case where the target multimedia file is a video, the target coordinate range is used to indicate an image area of each of at least one video frame of the video.
Further optionally, in this embodiment of the application, the first display control device may detect the header file, so as to obtain the target coordinate range and the target parameter adjustment value from the header file.
Step 202, the first display control device determines a target image area from the image area corresponding to the target multimedia file according to the target coordinate range.
Further optionally, in this embodiment of the application, the first display control device may determine an image area corresponding to the target coordinate range as a target image area, so as to determine the target image area from the image area corresponding to the target multimedia file.
In step 102a1, the first display control means adjusts the display parameter of the target image area based on the target parameter adjustment value.
Further optionally, in this embodiment of the application, the first display control device may first determine the target parameter adjustment value, determine whether the target parameter adjustment value is within a parameter adjustment range of the display parameter corresponding to the target parameter adjustment value, and adjust the display parameter of the target image area according to the determination result.
The above "target parameter adjustment value is within the parameter adjustment range of the display parameter corresponding to the target parameter adjustment value" may be understood as: the target parameter adjustment value is less than or equal to a parameter maximum adjustment threshold of a certain display parameter of the first display control device and is greater than or equal to a parameter minimum adjustment threshold of the certain display parameter of the first display control device; wherein, the certain display parameter is a display parameter corresponding to the target parameter adjustment value.
Further optionally, in this embodiment of the application, under the condition that the target parameter adjustment value is within the parameter adjustment range of the display parameter corresponding to the target parameter adjustment value, the first display control device may adjust the parameter value of the display parameter of the target image area according to the target parameter adjustment value.
It can be understood that, if the target parameter adjustment value is within the parameter adjustment range of the display parameter corresponding to the target parameter adjustment value, it may be considered that the first display control device is capable of adjusting the parameter value of the display parameter of the target image area according to the target parameter adjustment value, and therefore, the first display control device may directly adjust the parameter value of the display parameter of the target image area.
Further optionally, in this embodiment of the application, under the condition that the target parameter adjustment value is outside the parameter adjustment range of the display parameter corresponding to the target parameter adjustment value, the first display control device may first adjust the target parameter adjustment value according to a preset rule, and then adjust the parameter value of the display parameter in the target image area according to the adjusted target parameter adjustment value.
It can be understood that, if the target parameter adjustment value is outside the parameter adjustment range of the display parameter corresponding to the target parameter adjustment value, it may be considered that the first display control device is unable to adjust the parameter value of the display parameter of the target image area according to the target parameter adjustment value, and therefore, the first display control device may first adjust the target parameter adjustment value to adjust the parameter value of the display parameter of the target image area according to the adjusted target parameter adjustment value.
Specifically, the preset rule may include any one of: critical value rule, equal proportion rule.
It should be noted that the above "critical value rule" can be understood as: the first display control device may adjust the target parameter adjustment value according to a maximum critical value or a minimum critical value in a range in which the display parameter corresponding to the target parameter adjustment value is adjusted by the first display control device. The above-mentioned "rule of equal proportions" can be understood as: the first display control means may adjust the target parameter adjustment value according to a certain ratio: and determining the maximum critical value or the minimum critical value in the parameter adjusting range of the display parameter corresponding to the target parameter adjusting value based on the target parameter adjusting value and the first display control device.
In the embodiment of the application, in the process of transmitting the target multimedia file through the application program of the second display control device, the application program may compress the target multimedia file, and therefore, when the target multimedia file is displayed, the display color of the first display control device may be different from the display color of the second display control device. In this way, the second display control device may first obtain the target coordinate range and the target parameter adjustment value, and store the target coordinate range and the target parameter adjustment value in the header file of the target multimedia file, that is, the target multimedia file is the original multimedia file of which the display parameters are not adjusted, so as to reduce the situation of different display colors caused by the compression processing of the target multimedia file by the application program. Next, the first display control device may receive the target multimedia file, and obtain the target coordinate range and the target parameter adjustment value from the header file in a case that the difference value between the first color gamut and the second color gamut is within a preset range, and then, the first display control device may adjust the display parameter of the image area corresponding to the target coordinate range based on the target parameter adjustment value.
In the embodiment of the application, under the condition that the display screen type of the display screen of the second display control device is the same as or similar to the display screen type of the display screen of the first display device, the first display control device may adjust the parameter value of the display parameter of the image area corresponding to the target coordinate range in the multimedia file according to the target parameter adjustment value, so that a situation that the display color of the first display control device is different from the display color of the second display control device due to the compression processing of the target multimedia file by the application program in the process of transmitting the target multimedia file may be reduced, and thus, the accuracy of displaying the color of the multimedia file by the first display control device may be improved.
In the following, how the first display control device adjusts the parameter value of the display parameter of the target image region will be described as an example of the first display control device adjusting the parameter value of the display parameter of the target image region based on the target parameter adjustment value.
Optionally, in this embodiment of the application, the target parameter adjustment value includes N parameter adjustment values of N display parameters; at least one first display parameter meeting preset conditions exists in the N display parameters, and the preset conditions comprise: the first parameter adjustment value of the first display parameter of the second display control device is larger than the maximum adjustment value of the first display parameter of the first display control device; n is a positive integer. Specifically, the step 102a1 can be realized by the step 102a2 or the step 102a3 described below.
In step 102a2, the first display control device adjusts the parameter adjustment values of the N display parameters of the first display control device to the maximum adjustment value of each display parameter.
It can be understood that, if the first parameter adjustment value of the first display parameter of the second display control device is greater than the maximum adjustment value of the first display parameter of the first display control device, the target parameter adjustment value may be considered to be outside the parameter adjustment range of the display parameter corresponding to the target parameter adjustment value, and therefore, the first display control device may adjust the parameter adjustment values of the N display parameters to the maximum adjustment value of each display parameter by using a threshold rule.
Further optionally, in this embodiment of the application, the N display parameters may include at least one of the following: saturation, hue, brightness, etc.; the N parameter adjustment values include at least one of: a saturation parameter adjustment value, a hue parameter adjustment value, a brightness parameter adjustment value, and the like.
In an embodiment of the present application, the first display parameter is: any one of the N display parameters; the maximum adjustment value of the first display parameter is: the maximum critical value of the parameter adjustment range of the first display parameter.
Illustratively, assume that the N display parameters include: saturation, hue and brightness, the N parameter adjustment values comprising: a first parameter adjustment value of saturation, a parameter adjustment value of hue, and a parameter adjustment value of brightness, the first parameter adjustment value being 0.8, the parameter adjustment value of hue being 100, the parameter adjustment value of brightness being 1.0, the maximum adjustment value of saturation of the first display control device being 0.6, the maximum adjustment value of hue being 120, and the maximum adjustment value of brightness being 1.2, the first display control device may adjust the parameter adjustment value of saturation to the maximum adjustment value of saturation, i.e., 0.6, and may adjust the parameter adjustment value of hue to the maximum adjustment value of hue, i.e., 120, and may adjust the parameter adjustment value of brightness to the maximum adjustment value of brightness, i.e., 1.2, in a case where the first parameter adjustment value of the first display parameter is greater than the maximum adjustment value of the first display parameter of the first display control device.
In this embodiment, if there is at least one first display parameter that satisfies the preset condition in the N display parameters, it may be considered that the display color of the second display control device is vivid when the target multimedia file is displayed, and therefore, the first display control device may adjust the parameter adjustment value of each display parameter in the N display parameters to the maximum adjustment value of each display parameter, so that when the target multimedia file is displayed, the display color of the first display control device is the same as or close to the display color of the second display control device.
In the embodiment of the application, under the condition that at least one first display parameter meeting the preset condition exists in the N display parameters, the first display control device can adjust the parameter adjustment value of each display parameter in the N display parameters to the maximum adjustment value of each display parameter, so that the situation that the display color of the first display control device is different from the display color of the second display control device when the target multimedia file is displayed can be avoided, and thus, the accuracy of the first display control device in displaying the color of the multimedia file can be improved.
Step 102a3, the first display control device obtains the ratio of the maximum adjustment value of the first display parameter of the first display control device to the original parameter value of the first display parameter of the second display control device, and increases the parameter values of the N display parameters according to the ratio.
It can be understood that, if the first parameter adjustment value of the first display parameter of the second display control device is greater than the maximum adjustment value of the first display parameter of the first display control device, the target parameter adjustment value may be considered to be outside the parameter adjustment range of the display parameter corresponding to the target parameter adjustment value, and therefore, the first display control device may adjust the parameter values of the N display parameters by using an equal-scale rule.
Further optionally, in this embodiment of the application, the original parameter values of the first display parameter may specifically be: the first display control device is obtained from a header file of the target multimedia file; or, the first display control device detects the target multimedia file.
Illustratively, assume that the N display parameters include: saturation, hue and brightness, the N parameter adjustment values comprising: a first parameter adjustment value of saturation, a parameter adjustment value of hue, and a parameter adjustment value of brightness, where the first parameter adjustment value is 0.8, the parameter adjustment value of hue is 100, the parameter adjustment value of brightness is 1.0, the maximum adjustment value of saturation of the first display control device is 0.6, the maximum adjustment value of hue is 120, the maximum adjustment value of brightness is 1.2, the original parameter value of saturation is 0.4, the original parameter value of hue is 80, and the original parameter value of brightness is 0.8, and when the parameter adjustment value of saturation is greater than the maximum adjustment value of the first display parameter of the first display control device, the first display control device may adjust the parameter adjustment value of saturation to the maximum adjustment value of saturation, that is, 0.6, and may adjust the maximum adjustment value of saturation according to a ratio of 0.6 to the original parameter value of saturation, that is, 3: and 2, increasing the parameter adjustment value of the hue, namely the parameter adjustment value of the adjusted hue is as follows: the parameter adjustment value for increasing the brightness, that is, the parameter adjustment value for the adjusted hue, is as follows, with the ratio of 80 × (3:2) ═ 120, and based on this ratio of 3: 2: 0.8 × (3:2) ═ 1.2.
In this embodiment of the application, if there is at least one first display parameter that meets a preset condition in the N display parameters, it may be considered that the display color of the second display control device is bright when the target multimedia file is displayed, and therefore, the first display control device may obtain a ratio of a maximum adjustment value of the first display parameter of the first display control device to an original parameter value of the first display parameter of the second display control device, and adjust the parameter values of the N display parameters according to the ratio, so that when the target multimedia file is displayed, the display color of the first display control device is the same as or close to the display color of the second display control device.
In the embodiment of the application, under the condition that the adjustment value corresponding to the second display parameter is outside the parameter adjustment range corresponding to the second display parameter, the first display control device can obtain the ratio of the maximum adjustment value of the first display parameter of the first display control device to the original parameter value of the first display parameter of the second display control device, and increase the parameter values of the N display parameters according to the ratio, so that the situation that the display color of the first display control device is different from the display color of the second display control device when the target multimedia file is displayed can be avoided, and thus, the accuracy of the first display control device in displaying the color of the multimedia file can be improved.
It should be noted that, the first display control device adjusts the parameter value of the display parameter of the target image area to be smaller based on the target parameter adjustment value, and reference may be made to the specific description in the above step, which is not repeated herein in this embodiment of the application.
In the following, it will be exemplified how the first display control device adjusts the target parameter by taking an example that the display screen type of the display screen of the second display control device is different from the display screen type of the display screen of the first display control device, that is, the hardware levels of the two display screens have a large difference.
Alternatively, in the embodiment of the present application, as shown in fig. 4 in combination with fig. 1, the step 102a may be replaced with a step 102b described below.
And 102b, under the condition that the first type of parameters and the second type of parameters are not matched, the first display control device adjusts the second type of parameters and the display parameters of the second display screen.
In the embodiment of the application, under the condition that the display screen type of the display screen of the second display control device is different from the display screen type of the display screen of the first display control device, the first display control device can adjust the second type of parameters and the display parameters of the second display screen first, then display the target multimedia file, but not directly display the target multimedia file, so that the situation that the color distortion occurs when the first display control device displays the target multimedia file can be avoided, and thus, the accuracy of the first display control device in displaying the color of the multimedia file can be improved.
Optionally, in this embodiment of the present application, the first type of parameter includes: the first color gamut of the first display screen, the second type of parameter includes: a second color gamut of the second display screen. Specifically, referring to fig. 4, as shown in fig. 5, the step 102b may be implemented by the step 102b1 or the step 102b2 described below.
Step 102b1, when the difference between the first color gamut and the second color gamut is outside the preset range and the first color gamut is smaller than the second color gamut, the first display control device compresses the second color gamut to the first color gamut, or reduces the parameter value of the display parameter of the second display screen according to the first preset value.
Further optionally, in this embodiment of the application, when the difference value between the first color gamut and the second color gamut is outside the preset range and the first color gamut is smaller than the second color gamut, the first display control device may obtain the first color gamut from the header file of the target multimedia file, so that the first display control device may compress the second color gamut to the first color gamut.
Further optionally, in this embodiment of the application, when the difference between the first color gamut and the second color gamut is outside the preset range and the first color gamut is smaller than the second color gamut, the first display control device may obtain the first preset value from the header file of the target multimedia file, or obtain the first preset value from the first display control device, so that the first display control device may reduce the parameter value of the display parameter of the second display screen according to the first preset value.
Alternatively, in the embodiment of the present application, the step 102b1 may be specifically implemented by the step 102b3 or the step 102b4 described below.
Step 102b3, when the difference between the first color gamut and the second color gamut is outside the preset range and the first color gamut is smaller than the second color gamut, the first display control device compresses the second color gamut to the first color gamut when the first display control device has the color processing function.
The above "having a color processing function" can be understood as: the first display control apparatus supports an ICC color management function. The above-mentioned "supporting ICC color management functions" can be understood as: when the first display control device is in the process of encoding and decoding the received multimedia file, the first display control device can modify the display color of the multimedia file through an ICC color management function so as to reduce the difference when different display control devices display the same color.
Further alternatively, in this embodiment of the present application, the first display control device may employ a first preset algorithm to compress the second color gamut to the first color gamut.
Further optionally, in this embodiment of the application, the first preset algorithm may specifically be: a gamut mapping algorithm.
It should be noted that, for the description of the color gamut mapping algorithm, reference may be made to specific descriptions in the related art, and details of the embodiments of the present application are not repeated herein.
Further alternatively, in this embodiment of the application, the first display control device may first use a first preset algorithm to obtain a first mapping matrix from the second color gamut to another color gamut, where the another color gamut may be an XYZ color gamut, so that the first display control device may adjust the second color gamut to the XYZ color gamut according to the first mapping matrix, and then use the first preset algorithm to obtain a second mapping matrix from the XYZ color gamut to the first color gamut, so that the first display control device may adjust the XYZ color gamut to the first color gamut according to the second mapping matrix.
In the embodiment of the application, the first display control device can compress the second color gamut to the first color gamut under the condition that the first display control device has the color processing function, so that the color gamut of the display screen of the first display control device is the same as the color gamut of the display screen of the second display control device, and thus, the condition that the display color of the first display control device is different from the display color of the display screen of the second display control device when the target multimedia file is displayed due to the fact that the display screen type of the display screen of the second display control device is different from the display screen type of the display screen of the first display control device can be avoided, and thus, the accuracy of the first display control device in displaying the color of the multimedia file can be improved.
Step 102b4, when the difference between the first color gamut and the second color gamut is outside the preset range and the first color gamut is smaller than the second color gamut, and the first display control device does not have the color processing function, the first display control device decreases the parameter value of the display parameter of the second display screen according to the first preset value.
Further optionally, in this embodiment of the application, the first display control device may adopt a second preset algorithm to reduce a parameter value of the display parameter of the second display screen.
Further optionally, in this embodiment of the application, the second preset algorithm may specifically be: a gamut compression mapping algorithm.

In this embodiment, if the difference between the first color gamut and the second color gamut is outside the preset range and the first color gamut is smaller than the second color gamut, it can be considered that the display color of the first display control device is bright when the target multimedia file is displayed, and therefore the first display control device can adjust the second color gamut or reduce the parameter value of the display parameter of the second display screen, so that the display color of the first display control device is the same as or close to the display color of the second display control device.
In the embodiment of the application, because the first display control device can compress the second color gamut to the first color gamut or reduce the parameter value of the display parameter of the second display screen according to the first preset value when the difference value between the first color gamut and the second color gamut is outside the preset range and the first color gamut is smaller than the second color gamut, the situation that the display color of the first display control device is different from the display color of the second display control device when the target multimedia file is displayed can be avoided, and thus, the accuracy of the first display control device in displaying the color of the multimedia file can be improved.
Step 102b2, when the difference between the first color gamut and the second color gamut is outside the preset range and the first color gamut is larger than the second color gamut, the first display control device increases the parameter value of the display parameter of the second display screen according to the second preset value.
Further optionally, in this embodiment of the application, the first display control device may adopt a third preset algorithm, and adjust a parameter value of the display parameter of the second display screen according to the second preset value.
Specifically, the third preset algorithm may specifically be: a color enhancement algorithm.
It should be noted that, for the description of the color enhancement algorithm, reference may be made to specific descriptions in the related art, and details are not repeated herein in the embodiments of the present application.
In the embodiment of the application, because the first display control device can adjust the parameter value of the display parameter of the second display screen according to the second preset value under the condition that the difference value between the first color gamut and the second color gamut is out of the preset range and the first color gamut is larger than the second color gamut, the display color of the first display control device can be the same as or close to the display color of the second display control device, and thus, the accuracy of the first display control device in displaying the color of the multimedia file can be improved.
