     The content distribution system of  FIG. 1  is configured by connecting a TV  1  and distribution servers  2 - 1  to  2 -N via a network  3  such as the Internet. For operation of the TV  1 , a remote controller  4  is used. From the remote controller  4  to the TV  1 , a command corresponding to a button pressed by a user is transmitted. 
     Between the TV  1  and the distribution servers  2 - 1  to  2 -N, communication via the network  3  is performed. The network  3  may be in any form of a wired network, a wireless network, or a combination of wired and wireless networks. Hereinafter, the distribution servers  2 - 1  to  2 -N are referred to as a distribution server  2  as appropriate, in a case where it is not necessary to distinguish from each other. 
     The TV  1 , which is an image processing apparatus, receives television broadcasts such as terrestrial digital broadcasts, satellite broadcasts, and cable broadcasts broadcast by broadcasting stations (not shown). Broadcasting of programing by the broadcasting stations is carried out in accordance with a predetermined schedule for each channel. 
     The TV  1  displays a video image of the broadcast programing on a display device, and outputs sound from a speaker. For example, the display device of the TV  1  is a display device having so-called 4K resolution (3840×2160) pixels and supporting HDR video image display. 
     Furthermore, the TV  1  has not only a function of receiving programing provided by broadcasting but also a function of receiving a content provided via the network  3 . The content is provided via the network  3 , for example, by streaming. The content may also be provided by download. 
     The TV  1  controls to display a main screen of the distribution service on the display device, in a case where a predetermined distribution service is selected by, for example, an operation using the remote controller  4 . In the TV  1 , it is possible to use multiple distribution services provided individually by different business operators. 
     The TV  1  receives and reproduces the content transmitted from the distribution server  2 . The TV  1  displays a video image obtained by reproducing video data included in the content on the display device, and outputs sound obtained by reproducing audio data from the speaker. 
     The distribution server  2  is a server to provide a distribution service. The distribution server  2 - 1  is a server to provide a distribution service A, and the distribution server  2 - 2  is a server to provide a distribution service B. The distribution server  2 -N is a server to provide a distribution service N. 
     One distribution service may be provided by one distribution server  2 , or may be provided by multiple distribution servers  2 . It is also possible to allow multiple distribution services to be provided by one distribution server  2 . 
     In this way, the user of the TV  1  can select a predetermined distribution service from multiple distribution services, and view a content provided by the selected distribution service. The TV  1  is equipment equipped with a general-purpose operating system (OS), and is installed with applications for using individual distribution services. 
       FIG. 2  is a diagram showing an example of an application structure of the TV  1 . 
     The TV  1  is equipped with a TV OS  11 . Various applications that operate on the TV OS  11  are installed on the TV  1 . The example of  FIG. 2  shows a TV viewing application  12 - 1 , a search application  12 - 2 , an image quality adjustment application  12 - 3 , and a content viewing applications  12 -A to  12 -N. 
     The TV viewing application  12 - 1  is an application that manages viewing of broadcast programing. While the TV viewing application  12 - 1  is running, the user can operate the remote controller  4  to select a predetermined channel and view programing broadcast on the selected channel. 
     The search application  12 - 2  is an application that searches for information on the Web on the basis of a keyword inputted by the user by operating the remote controller  4  or by sound. 
     The image quality adjustment application  12 - 3  is an application that manages image quality adjustment of the display device of the TV  1 . In a case where the user instructs performing of image quality adjustment, the image quality adjustment application  12 - 3  controls to display an image quality adjustment menu, which is a graphical user interface (GUI) for setting various items related to the image quality. 
     The image quality adjustment application  12 - 3  sets image quality adjustment parameters of various items such as a picture mode, brightness, and hue, in accordance with a user&#39;s operation on the image quality adjustment menu. An image quality adjustment function and an image quality adjustment menu display function of the image quality adjustment application  12 - 3  may be provided as functions of the TV OS  11 . 
     The content viewing application  12 -A is an application for using the distribution service A provided by the distribution server  2 - 1 . 
     For example, when the content viewing application  12 -A is starting-up, a main screen of the distribution service A is displayed on the TV  1  on the basis of information transmitted from the distribution server  2 - 1 . The main screen displays information regarding viewable contents, such as titles and thumbnail images, and the user can see these pieces of information and select a desired content. When the user selects a predetermined content, distribution of the content is started. 
     The content viewing application  12 -B is an application for using the distribution service B provided by the distribution server  2 - 2 . 
     Although not shown in  FIG. 2 , dedicated applications for using other distribution services are individually installed on the TV  1 . 
     Furthermore, the TV  1  is also installed with applications such as a video application used for viewing recorded programing recorded on an external recording medium such as a hard disk drive (HDD), and a Web browser used for displaying a Web page. 
     For example, the TV viewing application  12 - 1 , the search application  12 - 2 , and the image quality adjustment application  12 - 3  are software prepared by a manufacturer that carries out manufacturing, selling, and the like of the TV  1 . The content viewing applications  12 -A to  12 -N are software prepared by business operators of the respective distribution services. 
     &lt;Display of Image Quality Adjustment Menu&gt; 
     Here, a display example of the image quality adjustment menu will be described. The image quality adjustment menu is displayed differently between a case where a content of a specific distribution service is being viewed and other cases. 
     In the following, it is assumed that the distribution service A provided by the distribution server  2 - 1  is the specific distribution service. 
     Example of During Programing Viewing 
       FIG. 3  is a view showing a display example of the image quality adjustment menu during programing viewing. 
     Soccer broadcast programing shown in an upper part of  FIG. 3  is, for example, recorded programing. That is, a screen shown in the upper part of  FIG. 3  is a screen when the video application used for viewing recorded programing is running. Recorded programing selected by the user is reproduced by the video application, and a video image is displayed on the display device. 
     In a case where an instruction is made to perform image quality adjustment while the screen as shown in the upper part of  FIG. 3  is displayed, an image quality adjustment menu  51  is displayed at a right edge of the screen, as shown at a tip of the arrow. In an area other than the display area of the image quality adjustment menu  51  in the entire screen, the video image of the recorded programing continues to be displayed. 
       FIG. 4  is an enlarged view showing the image quality adjustment menu  51  of  FIG. 3 . 
     As shown in  FIG. 4 , in the image quality adjustment menu  51 , individual items related to image quality adjustment are displayed vertically side by side. A broken line indicating a boundary of display areas of individual items is not a line actually displayed on the image quality adjustment menu  51 . 
     In an area  61  in an upper part of the image quality adjustment menu  51 , the characters “Picture adjustments” indicating the image quality adjustment menu are displayed, and “Apps (Video)” is displayed below. The “Apps (Video)” indicates that the running application is a video application. 
     In this way, information indicating the running application is displayed in the area  61 . For example, in a case where the TV viewing application  12 - 1  is running and broadcast programing is being viewed, “Apps (Tuner)” indicating that the TV viewing application  12 - 1  is running is displayed. 
     Areas  62  to  67  are sequentially formed below the area  61 . To the areas  62  to  67 , items related to image quality adjustment are assigned. The user can operate the remote controller  4  to select a predetermined item to change setting of the selected item. 
     The area  62  is an area used for setting of Picture mode. The Picture mode is an overall image quality adjustment mode. In the example of  FIG. 4 , “Standard” is set. 
     For example, in a case where the item “Picture mode” is selected, as shown in  FIG. 5 , a selection menu  51 A of the Picture mode is displayed instead of the image quality adjustment menu  51 . In the example of  FIG. 5 , “Vivid”, “Standard”, and “Cinema” are displayed as setting values of the Picture mode. The user operates the remote controller  4  and selects a predetermined setting value from the setting values displayed on the selection menu  51 A. 
     Returning to the description of  FIG. 4 , the area  63  is an area used for setting of Auto picture mode. The Auto picture mode is a function of automatically switching the image quality in accordance with a content being viewed. In the area  63 , a switch  63 A indicating on/off of the Auto picture mode is displayed. The user can select the item “Auto picture mode” to change on/off setting of the Auto picture mode. Here, on/off of the Auto picture mode is displayed in the area  63 , but the “Auto picture mode” may be displayed and selected together with “Vivid”, “Standard”, and “Cinema” as the setting values of the Picture mode. 
     The area  64  is an area used for setting of Brightness. The Brightness represents luminosity (brightness). In the example of  FIG. 4 , a setting value “Max” is set. The user can select the item “Brightness” to change the luminosity setting. 
     The area  65  is an area used for setting of Color. The Color represents hue. In the example of  FIG. 4 , a setting value “60” is set. The user can select the item “Color” to change setting of hue. 
     The area  66  is an area used for setting of Light sensor. The Light sensor is a function of automatically adjusting screen luminosity in accordance with ambient luminosity. In the area  66 , a switch  66 A that represents on/off of the Light sensor is displayed. 
     The user can select the item “Light sensor” to change on/off setting of the Light sensor function. In the example shown in  FIG. 4 , the Light sensor function is on and the switch  66 A is displayed in a bright color. A hatched indication shows that the switch  66 A is displayed in a bright color. 
     The area  67  is an area used for detailed setting. The user can select the item of detailed setting to change multiple detailed setting related to image quality. 
     While viewing of recorded programing or broadcast programing, the image quality is adjusted using the image quality adjustment menu  51  as described above. 
     While viewing of a content provided by a distribution service other than the distribution service A, which is a specific distribution service, the image quality is also adjusted by using a similar image quality adjustment menu  51 . 
     For example, in a case where an instruction is made to perform image quality adjustment while viewing of a content provided by the distribution service B, for example, “Service B app” indicating that the running application is the content viewing application  12 -B is displayed in the area  61 . Furthermore, in a case where an instruction is made to perform image quality adjustment while viewing of a content provided by the distribution service N, for example, “Service N app” indicating that the running application is the content viewing application  12 -N is displayed in the area  61 . 
     Example of During Content Viewing of Specific Distribution Service 
       FIG. 6  is a view showing a display example of the image quality adjustment menu during content viewing of the distribution service A. 
     A content shown in an upper part of  FIG. 6  is, for example, a movie provided by the distribution service A. A content selected by the user is reproduced by the content viewing application  12 -A, and a video image of the content is displayed on the display device. 
     In a case where an instruction is made to perform image quality adjustment while the screen as shown in the upper part of  FIG. 6  is displayed, the image quality adjustment menu  51  is displayed at a right edge of the screen, as shown at a tip of the arrow. In an area other than the display area of the image quality adjustment menu  51  in the entire screen, the video image of the content continues to be displayed. 
       FIG. 7  is an enlarged view showing the image quality adjustment menu  51  of  FIG. 6 . 
     In display of the image quality adjustment menu  51  shown in  FIG. 7 , the same display as that described with reference to  FIG. 4  is denoted by the same reference numeral. Redundant descriptions will be omitted as appropriate. 
     As shown in  FIG. 7 , “Service A app” indicating that the running application is the content viewing application  12 -A is displayed in the area  61 . 
     In the image quality adjustment menu  51  of  FIG. 7 , the area  63  is an area used for setting of Service A calibrated mode. That is, the area  63  becomes an area for the Service A calibrated mode, instead of the Auto picture mode. In the area  63 , a switch  63 B indicating on/off of the Service A calibrated mode is displayed. 
     The Service A calibrated mode is an image quality adjustment mode for the distribution service A. 
     In a case where the Service A calibrated mode is on, image quality adjustment of a content of the distribution service A is performed in accordance with image quality adjustment parameters set for the distribution service A. For example, image quality adjustment with the Service A calibrated mode is performed by using image quality adjustment parameters common to all the contents distributed by the distribution service A. 
     The image quality adjustment parameters for the distribution service A are preset and managed by the content viewing application  12 -A. The image quality adjustment parameters for the distribution service A may be acquired from the distribution server  2 - 1  at a timing when the Service A calibrated mode is set to on. 
     Whereas, in a case where the Service A calibrated mode is off, the image quality adjustment of a content of the distribution service A is performed in accordance with image quality adjustment parameters set by the user using display of other areas including the Picture mode. The Picture mode can also be used for image quality adjustment of the content of the distribution service A in a case where the Service A calibrated mode is off, in addition to image quality adjustment of programing and image quality adjustment of contents of distribution services other than the distribution service A. 
     In the example shown in  FIG. 7 , the Service A calibrated mode is set to off. For example, default setting for the Service A calibrated mode is off. 
     Items in other areas are the same as those described with reference to  FIG. 4 . 
     In the example of  FIG. 7 , the Brightness of the area  64  is set to “35”, and the Color of the area  65  is set to “50”. Furthermore, setting of the Light sensor in the area  66  is turned off. 
       FIG. 8  is a view showing a display example of the image quality adjustment menu  51 . 
     In a case where the Service A calibrated mode is set to on, the area  62  is displayed to be grayed out to indicate an inoperable state. That is, it is prohibited to change the setting of the Picture mode. As the image quality adjustment mode, setting of the Service A calibrated mode has priority over setting of the Picture mode. 
     In the example of  FIG. 8 , the switch  63 B in the area  63  is on, and the switch  63 B is displayed in a prominent color. 
       FIG. 9  is a view showing a display example of the image quality adjustment menu  51  in a case where the Service A calibrated mode has been set to on. 
     In a case where the Service A calibrated mode has been set to on, the Picture mode is displayed to be grayed out as shown in an upper part of  FIG. 9 . In this state, in a case where the user operates the remote controller  4  to select the area  62  of the Picture mode, a message  91  is displayed notifying that a change of the Picture mode is prohibited, as shown at a tip of the arrow. 
     In a case of changing the Picture mode, the user switches setting of the Service A calibrated mode to off, and thereafter, changes the Picture mode. 
     Returning to the description of  FIG. 8 , the Brightness of the area  64  is set to “40”, and the Color of the area  65  is set to “70”. Setting of these Brightness and Color is setting based on the image quality adjustment parameters for the distribution service A. Other items included in the detailed setting are also set as appropriate on the basis of the image quality adjustment parameters for the distribution service A. 
     Even in a case where the Service A calibrated mode has been set to on, items other than the Picture mode are displayed in an operable state. The user can change setting for the items other than the Picture mode. 
     In this way, the TV  1  is provided with the Service A calibrated mode, which is an image quality adjustment mode for the distribution service A. 
     Image quality adjustment parameters of the Service A calibrated mode are, for example, parameters prepared by a business operator of the distribution service A. For contents of the distribution service A, image quality adjustment intended by the business operator of the distribution service A is applied. 
     The business operator of the distribution service A can allow the user to view a video image with image quality intended by the business operator side. 
     Also as the user, it is possible to view the video image of the content with the image quality intended by the business operator side. 
     Processing of the TV  1  to perform the image quality adjustment as described above will be described later with reference to a flowchart. 
     &lt;Configuration and Operation of TV&gt; 
     Configuration of TV 
       FIG. 10  is a block diagram showing a hardware configuration example of the TV  1 . 
     A tuner  101  receives a broadcast wave signal supplied from an antenna (not shown) or a broadcast wave signal supplied from a satellite broadcast or cable TV set-top box, and extracts a signal of a channel selected by the user. The tuner  101  performs various processes such as A/D conversion and demodulation on the extracted signal, and outputs programing data acquired by performing various processes, to a decoder  102 . 
     The decoder  102  decodes a video stream included in the programing data, and outputs data of each picture obtained by decoding, to a signal processing unit  103 . Furthermore, the decoder  102  decodes an audio stream included in the programing data, and outputs sound data of the programing to the signal processing unit  103 . 
     In a case of reproducing a content of a predetermined distribution service, the decoder  102  decodes a video stream and an audio stream of a content received by a communication unit  111  and supplied via a bus  106 . The decoder  102  outputs data of each picture obtained by decoding the video stream of the content and sound data obtained by decoding the audio stream, to the signal processing unit  103 . 
     The signal processing unit  103  performs image quality adjustment of each picture supplied from the decoder  102  in accordance with control by a CPU  107 . The signal processing unit  103  outputs a picture after the image quality adjustment to a display device  104 , and controls to display a video image of the programing or the content. 
     Furthermore, the signal processing unit  103  performs D/A conversion and the like of sound data supplied from the decoder  102 , synchronizes with the video image, and outputs sound of the programing or the content from a speaker  105 . 
     The display device  104  is a display having 4K resolution pixels and supporting HDR video image display. The display device  104  includes a liquid crystal display (LCD), an organic EL display, or the like. 
     The central processing unit (CPU)  107 , a read only memory (ROM)  108 , and a random access memory (RAM)  109  are mutually connected by the bus  106 . The CPU  107  executes a program recorded in the ROM  108  or a recording unit  110  by using the RAM  109 , and controls the entire TV  1 . 
     The recording unit  110  includes a recording medium such as a hard disk drive (HDD) or a solid state drive (SSD). The recording unit  110  records various data such as programing data, contents, EPG data, and programs. 
     The communication unit  111  is an interface of the network  3 . The communication unit  111  communicates with the distribution server  2 . 
     An operation I/F unit  112  receives a command transmitted from the remote controller  4  and outputs to the CPU  107  via the bus  106 . 
       FIG. 11  is a block diagram showing a functional configuration example of the TV  1 . 
     As shown in  FIG. 11 , in the TV  1 , a content reproduction control unit  121 , an image quality adjustment control unit  122 , and a menu display control unit  123  are realized. 
     At least a part of functional units shown in  FIG. 11  is realized by executing a predetermined program by the CPU  107  of  FIG. 10 . For example, the content reproduction control unit  121  is realized by executing the content viewing application  12 -A. The image quality adjustment control unit  122  and the menu display control unit  123  are realized by executing the image quality adjustment application  12 - 3 . 
     The content reproduction control unit  121  communicates with the distribution server  2 - 1  by controlling the communication unit  111 , and requests the distribution server  2 - 1  to transmit a content selected by the user. The content reproduction control unit  121  controls the decoder  102  to reproduce the content transmitted from the distribution server  2 - 1 . 
     The image quality adjustment control unit  122  controls image quality adjustment of programing or contents performed by the signal processing unit  103 . 
     For example, in a case of reproducing a content of the distribution service A, which is the specific distribution service, the image quality adjustment control unit  122  controls to perform image quality adjustment in accordance with image quality adjustment parameters for the distribution service A, in a case where the Service A calibrated mode has been set to on. The image quality adjustment parameters for the distribution service A include, for example, a set of a plurality of parameters representing setting values of a plurality of items. 
     Furthermore, at a time of reproducing programing, or of reproducing a content of a distribution service other than the distribution service A, the image quality adjustment control unit  122  controls to perform image quality adjustment in accordance with image quality adjustment parameters individually set by the user. 
     The menu display control unit  123  causes the display device  104  to display the image quality adjustment menu, in a case where an instruction is made to perform image quality adjustment. Furthermore, the menu display control unit  123  switches display of the image quality adjustment menu in accordance with a user&#39;s operation as described above. 
     Operation of TV 
     Here, with reference to a flowchart in  FIG. 12 , an image quality adjustment process of the TV  1  will be described. 
     The process of  FIG. 12  is started, for example, when the user instructs performing of image quality adjustment. 
     In step S 10 , the menu display control unit  123  determines whether or not a content of the distribution service A, which is the specific distribution service, is being viewed. 
     In a case where it is determined in step S 1  that the content of the distribution service A is being viewed, in step S 2 , the menu display control unit  123  controls to display the image quality adjustment menu ( FIG. 7 ) including the item of the Service A calibrated mode, which is an image quality adjustment mode for the distribution service A. 
     In step S 3 , the menu display control unit  123  switches display of the image quality adjustment menu as described above in accordance with a user&#39;s operation. 
     In step S 4 , the menu display control unit  123  determines whether or not to close the image quality adjustment menu. When the image quality adjustment menu is to be closed, the process returns to step S 3 , and display of the image quality adjustment menu continues until the determination is made in step S 4 . 
     In a case where it is determined in step S 4  that the image quality adjustment menu is to be closed, in step S 5 , the image quality adjustment control unit  122  controls image quality adjustment of the content of the distribution service A, and controls to display a video image after the image quality adjustment. For example, in a case where the Service A calibrated mode is set to on with use of the image quality adjustment menu, the image quality adjustment control unit  122  controls to perform the image quality adjustment in accordance with the image quality adjustment parameters for the distribution service A. 
     Whereas, in a case where it is determined in step S 1  that the content of the distribution service A is not being viewed, in step S 6 , the menu display control unit  123  controls to display the normal image quality adjustment menu ( FIG. 4 ). The image quality adjustment menu displayed here does not include the item of the Service A calibrated mode. 
     In step S 7 , the menu display control unit  123  switches display of the normal image quality adjustment menu in accordance with a user&#39;s operation. 
     In step S 8 , the menu display control unit  123  determines whether or not to close the normal image quality adjustment menu. When the normal image quality adjustment menu is to be closed, the process returns to step S 7 , and display of the normal image quality adjustment menu continues until the determination is made in step S 8 . 
     In a case where it is determined in step S 8  that the normal image quality adjustment menu is to be closed, in step S 9 , the image quality adjustment control unit  122  controls the image quality adjustment of programing or a content in accordance with setting by the user, and controls to display a video image after the image quality adjustment. 
     After the image quality adjustment is performed in step S 5  or step S 9 , the process ends. 
     By the process described above, the business operator of the distribution service A can allow the user to view a video image with image quality intended by the business operator side. Furthermore, the user can view the video image of the content with the image quality intended by the business operator side. 
     Note that the content distributed by the distribution service A may be a content in which an SDR video image is recorded, or may be a content in which an HDR video image is recorded. The maximum brightness of the SDR video image is 100 nits (100 cd/m 2 ), while the maximum brightness of the HDR video image exceeds that, for example, 10000 nits. 
     In a case where the display device  104  of the TV  1  is a display that supports HDR video image display as described above, a range of adjustment is wide. Therefore, there is a possibility that the user performs image quality adjustment different from the one intended by the business operator side. It is considered that preparing the Service A calibrated mode, which is the image quality adjustment mode for the distribution service A, is particularly effective at a time of displaying the content containing the HDR video image. 
     Modified Example 
     Setting Example of Image Quality Adjustment Parameter 
     It has been assumed that the image quality adjustment parameters used in a case where the Service A calibrated mode is set to on are the image quality adjustment parameters common to all the contents distributed by the distribution service A. However, the image quality adjustment parameters may be prepared for each content. In this case, the image quality adjustment parameters are prepared by, for example, a creator of the content, and are managed by the distribution server  2 - 1 . 
     An image quality adjustment process in a case where the image quality adjustment parameters are prepared for each content will be described with reference to a flowchart of  FIG. 13 . 
     The process of  FIG. 13  is started, for example, when the Service A calibrated mode is set to on. 
     In step S 21 , the image quality adjustment control unit  122  communicates with the distribution server  2 - 1 , which is a server of the specific distribution service, and acquires image quality adjustment parameters for a content to be reproduced. 
     In step S 22 , the image quality adjustment control unit  122  causes the signal processing unit  103  to perform image quality adjustment of the content in accordance with the image quality adjustment parameters acquired from the distribution server  2 - 1 . 
     Therefore, the creator of the content distributed by the distribution service A can allow the user to view a video image with image quality intended by the creator side. 
     The image quality adjustment parameters may be prepared for each genre of contents distributed by the distribution service A, or may be prepared for each model of the TV  1 . Furthermore, the image quality adjustment parameters may be prepared for each display performance of the display device  104  included in the TV  1 . 
     Example of Device 
     The image quality adjustment as described above by the TV  1  may be performed on reproduction equipment  201  shown in A of  FIG. 14  or a mobile terminal  202  shown in B of  FIG. 14 . The reproduction equipment  201  is a device such as a set-top box or equipment that supports reproduction of a predetermined package medium. 
     For example, in a case where the Service A calibrated mode has been set to on, the reproduction equipment  201  performs image quality adjustment of contents on the basis of the image quality adjustment parameters for the distribution service A, and outputs a video image after the image quality adjustment to the TV  1  to be displayed. 
     Other Examples 
     As parameters for a specific distribution service, parameters used for image quality adjustment are prepared, but parameters used for sound quality adjustment of the sound of the content may also be prepared. 
     In a case where the Service A calibrated mode has been set to on, the TV  1  is to adjust sound of a content on the basis of the parameters for the distribution service A, and output sound after the sound quality adjustment. 
     &lt;Example of Case where there are Multiple Specific Distribution Services&gt; 
     A description has been given to a case where the specific distribution service is one, which is the distribution service A, but multiple distribution services may be prepared as the specific distribution services. 
     In this case, the user can use an image quality adjustment function similar to the Service A calibrated mode described above not only for viewing the distribution service A but also for viewing contents of other distribution services such as the distribution service B and a distribution service C. 
       FIG. 15  is a diagram showing an example of providing image quality adjustment parameters. 
     In a case where the content viewing application  12 -A is running on the TV  1 , communication is performed between the content viewing application  12 -A and the distribution server  2 - 1 , and the distribution server  2 - 1  provides the content viewing application  12 -A with image quality adjustment parameters for the distribution service A, as shown by arrow #1. 
     The image quality adjustment parameters may be provided at a timing when the Service A calibrated mode is set to on as described above, or may be provided at any timing such as a timing when the distribution of the content is started. 
     In a case where the Service A calibrated mode has been set to on, image quality adjustment of a content of the distribution service A is performed on the basis of the image quality adjustment parameters provided by the distribution server  2 - 1 . The acquisition of the image quality adjustment parameters and the image quality adjustment based on the image quality adjustment parameters are performed by, for example, the image quality adjustment control unit  122 . 
     Such provision of image quality adjustment parameters is also performed by distribution servers that manage provision of other distribution services. 
       FIG. 16  is a diagram showing another example of providing image quality adjustment parameters. 
     For example, in a case where an image quality adjustment mode for the distribution service B has been prepared, image quality adjustment parameters to be used in the image quality adjustment mode for the distribution service B are provided by the distribution server  2 - 2  that manages provision of the distribution service B. 
     That is, communication is performed between the content viewing application  12 -B ( FIG. 2 ) running on the TV  1  and the distribution server  2 - 2 , and the distribution server  2 - 2  provides the content viewing application  12 -B with image quality adjustment parameters for the distribution service B, as shown by arrow #2. 
     The image quality adjustment parameters for the distribution service B are also provided at any timing such as a timing when the image quality adjustment mode for the distribution service B is set to on, or a timing when the content distribution is started. 
     In a case where the image quality adjustment mode for the distribution service B has been set to on, image quality adjustment of a content of the distribution service B is performed on the basis of the image quality adjustment parameters provided by the distribution server  2 - 2 . 
     In a case where image quality adjustment modes for multiple distribution services are prepared in this way, display of an image quality adjustment menu is different from display of the image quality adjustment menu  51  described with reference to  FIG. 8  and the like. 
     About Screen Display 
       FIG. 17  is a view showing a display example of an image quality adjustment menu. 
     In a case where an instruction is made to perform image quality adjustment while viewing of the content of the distribution service A, an image quality adjustment menu  301  is displayed at a right edge of the screen, as shown in an upper part of  FIG. 17 . In an area other than the display area of the image quality adjustment menu  301  in the entire screen, a video image of the content of the distribution service A continues to be displayed. 
     In the image quality adjustment menu  301 , items similar to those of the image quality adjustment menu  51  described above are displayed vertically side by side. Redundant descriptions will be omitted as appropriate. 
       FIG. 18  is an enlarged view showing the image quality adjustment menu  301  of  FIG. 17 . 
     An area  301 A in an uppermost part is an area to display information indicating a type of input (input type) for the display device  104 . In the example of  FIG. 18 , the input type is “Partner App”. 
     The “Partner App” indicates that an application for using a distribution service for which a dedicated image quality adjustment mode is prepared is being executed, and a video image acquired by the application is displayed on the display device  104 . 
     “Partner” is the business operator of the distribution service A, the business operator of the distribution service B, and the like for which a dedicated image quality adjustment mode has been prepared. Hereinafter, an image quality adjustment mode dedicated to the “Partner” is referred to as “Partner calibrated mode” as appropriate. 
     Areas  311  to  316  below the area  301 A are areas to be used for a user&#39;s operation. To the areas  311  to  316 , items related to image quality adjustment are assigned. The user can operate the remote controller  4  to select a predetermined item to change setting of the selected item. 
     The area  311  is an area used for setting of the Picture mode. In the example of  FIG. 18 , “Standard” is set as the Picture mode. 
     The area  312  is an area used for setting of the Auto picture mode. 
     Display of the area  311  and the area  312  is individually the same as display of the area  62  and the area  63  described with reference to, for example,  FIG. 4 . 
     The area  313  is an area used for setting of the Partner calibrated mode, which is an image quality adjustment mode dedicated to “Partner”. Since a content of the distribution service A is being viewed, the characters “Partner calibrated mode for Service A” are displayed in the area  313  of  FIG. 18 . The “Partner calibrated mode for Service A” is the same as the Partner calibrated mode of the distribution service A, that is, the Service A calibrated mode described above. 
     Note that, in the example of  FIG. 18 , setting of the Partner calibrated mode is turned off. Default setting of the Partner calibrated mode is, for example, off. 
     In a case where the user selects the area  313  by operating the remote controller  4 , it becomes possible to select on/off of the Partner calibrated mode. 
     The area  314  is an area used for setting of the Brightness as an image quality adjustment parameter. In the example of  FIG. 18 , a setting value “35” is set. 
     The area  315  is an area used for setting of the Color as an image quality adjustment parameter. In the example of  FIG. 18 , a setting value “60” is set. 
     Display of the area  314  and the area  315  is individually the same as display of the area  64  and the area  65  described with reference to, for example,  FIG. 8 . In a case where the Partner calibrated mode is off, the user can freely set the image quality adjustment parameters of the Brightness and the Color. 
     The area  316  is an area used for setting of Partner Offset. The Partner Offset is Offset used for image quality adjustment in a case where the Partner calibrated mode has been set to on. Using an Offset value set as the Partner Offset enables further adjustment to be made to the image quality adjustment, with the image quality adjustment parameters set with the Partner calibrated mode. 
     That is, by setting the Partner Offset, the user can also view a video image with image quality finely adjusted in accordance with user&#39;s preference, rather than an original video image as it is of the Partner calibrated mode (a video image after image quality adjustment with use of the image quality adjustment parameters provided by the distribution service). 
     The area  316  is displayed to be grayed out in a case where the Partner calibrated mode has been set to off, as shown in  FIG. 18 . In this case, setting of the Partner Offset is disabled. 
     In  FIG. 18 , the fact that the area  316  is colored indicates that the area  316  is displayed to be grayed out. The areas  311  to  315  that are not grayed out are areas that can be operated by the user. 
     With use of such display of the image quality adjustment menu  301 , the user can perform image quality adjustment of a content of the distribution service A. 
     Returning to the description in  FIG. 17 , in a case where the Partner calibrated mode (the Partner calibrated mode for Service A) is set to on, as shown at a tip of arrow #11, a video image of the content is switched to a video image after image quality adjustment with the Partner calibrated mode. Image quality adjustment using parameters provided by the distribution service A, as image quality adjustment parameters such as the Brightness and the Color, is performed on the content. In the example of  FIG. 17 , setting values of “60” as the Brightness and “50” as the Color are used as the image quality adjustment parameters of the Partner calibrated mode. 
     In the image quality adjustment menu  301 , among the areas  311  to  316 , only the area  313  of the Partner calibrated mode and the area  316  of the Partner Offset are operable, and other areas are displayed to be grayed out. 
     In the image quality adjustment menu  301  in a lower part of  FIG. 17 , setting of the Partner calibrated mode of the area  313  has been turned on. Furthermore, the setting of the Picture mode of the area  311  is “Partner calibrated” indicating that the Partner calibrated mode has priority. 
     In this state, in a case where the Partner calibrated mode is set to off, as shown at a tip of arrow #12, a video image of the content is switched to a video image that has not been subjected to the image quality adjustment with the Partner calibrated mode. Display of the image quality adjustment menu  301  will also return to display in an off state before the Partner calibrated mode has been set to on. 
       FIG. 19  is a view showing a display example when the Partner Offset is set. 
     As shown in an upper part of  FIG. 19 , in a case where the Partner calibrated mode is on, when selection is made to set the Partner Offset in a bottom column of the image quality adjustment menu  301 , an Offset menu  302  is displayed instead of the image quality adjustment menu  301 , as shown at a tip of arrow #13. The Offset menu  302  is display to be used for setting of the Partner Offset. 
       FIG. 20  is an enlarged view showing the Offset menu  302 . 
     In an area  302 A in an uppermost part, the characters “Partner Offset (Service A)” indicating that the Offset menu  302  is a menu to be used for setting of the Partner Offset are displayed. 
     Areas  331  and  332  below the area  302 A are areas to be used for a user&#39;s operation. 
     In the example of  FIG. 20 , the area  331  is an area used for setting of an Offset value of the Brightness. Furthermore, the area  332  is an area used for setting of an Offset value of the Color. 
     The user can set the Offset value of the Brightness by selecting the area  331 . Furthermore, the user can set the Offset value of the Color by selecting the area  332 . 
     Setting of the Offset value is performed by using options that use relative expressions with respect to a criterion, for example, such as selecting one of five levels, or selecting any level from +5/+3/−3/−5. 
     That is, the unit of the Offset value is different from the unit of the adjustment parameters such as the Brightness and the Color. As a value of the Offset value, absolute numerical values such as values indicating the Brightness and the Color (“35” and “60” in  FIG. 18 ) are not used. 
     For example, in a case where “+5” is selected as the Offset value of the Brightness, a predetermined value corresponding to “+5” is added to “60”, which is the Brightness specified with the Partner calibrated mode, and a value after the addition is used to adjust the Brightness. 
     After the Offset value is set, display is returned to a state of the upper part of  FIG. 19 , in which the image quality adjustment menu  301  is displayed. 
     Note that, in the example of  FIG. 19 , it is assumed that there are two Offset values that can be set with use of the Offset menu  302 : the Offset value of the Brightness and the Offset value of the Color. However, the number of items displayed in the Offset menu  302  will be different for each the Partner calibrated mode. For example, in the Partner calibrated mode of the distribution service B (Partner calibrated mode for Service B), it is also possible to enable setting of Offset values of more types of image quality adjustment parameters. 
     Even while viewing the content of the distribution service B, various kinds of setting related to image quality adjustment, including setting of the Partner calibrated mode, are made using display similar to the display above. 
       FIG. 21  is a view showing a display example of a screen for each distribution service. 
     Display shown on a left side of  FIG. 21  shows the screen display described above in a case where the content viewing application  12 -A is running and a content of the distribution service A is being viewed. An upper part shows display in a case where the Partner calibrated mode for Service A is off, and a middle part shows display in a case where the Partner calibrated mode for Service A is on. A lower part shows display of the Offset menu  302 . 
     Whereas, display shown on a right side of  FIG. 21  shows screen display in a case where the content viewing application  12 -B is running and a content of the distribution service B is being viewed. An upper part shows display in a case where the Partner calibrated mode for Service B is off, a middle part shows display in a case where the Partner calibrated mode for Service B is on. A lower part shows display of the Offset menu  302 . 
     As shown by arrow #21, display of an input type of the image quality adjustment menu  301  is to be “Partner App” in common to both the case where the content viewing application  12 -A is running and the case where the content viewing application  12 -B is running. 
     As shown by arrows #22 and #24, display of the Picture mode in the image quality adjustment menu  301  is common in the case where the content viewing application  12 -A is running and the case where the content viewing application  12 -B is running. In a case where the Partner calibrated mode is off, a setting value such as “Standard” is displayed to indicate user&#39;s selection contents (arrow #22). In a case where the Partner calibrated mode is on, “Partner calibrated” is displayed to indicate that the Partner calibrated mode has priority (arrow #24). 
     As shown by arrow #23, the Partner calibrated mode can be individually set on/off for each of the content viewing application  12 -A and the content viewing application  12 -B. 
     As shown by arrow #25, setting of the Partner Offset with use of the Offset menu  302  can be individually held for each application of the content viewing application  12 -A and the content viewing application  12 -B. The Offset value of the Partner Offset set in a case where the Partner calibrated mode for Service A is on is used for image quality adjustment with the Partner calibrated mode for Service A. Furthermore, the Offset value of the Partner Offset set in a case where the Partner calibrated mode for Service B is on is used for image quality adjustment with the Partner calibrated mode for Service B. 
     As described above, for the case where the content viewing application  12 -A is running and the case where the content viewing application  12 -B is running, setting for image quality adjustment is made with use of similar user interfaces. 
     About Management of Image Quality Adjustment Parameters 
       FIG. 22  is a view showing an example of management of image quality adjustment parameters. 
     As shown in  FIG. 22 , the image quality adjustment parameters in the Partner calibrated mode are stored and managed in a parameter storage area M 1  as table information, together with image quality adjustment parameters of other input types such as TV and HDMI (registered trademark). 
     Whereas, the Offset value of the Partner Offset is stored and managed in an Offset storage area M 2 , which is a storage area different from the parameter storage area M 1 , for each application. 
     For example, the parameter storage area M 1  is formed in the RAM  109  ( FIG. 10 ), which is a volatile storage area. The Offset storage area M 2  is formed in the recording unit  110 , which is a non-volatile storage area. The parameter storage area M 1  and the Offset storage area M 2  may be formed, for example, in the same non-volatile storage unit (medium). 
     The table information stored in the parameter storage area M 1  is formed by associating multiple types of image quality adjustment parameters for each input type. In some image quality adjustment parameters, the same value is used commonly for multiple input types. Image quality adjustment parameters that are commonly used by multiple input types cannot be rewritten from content viewing applications such as the content viewing application  12 -A and the content viewing application  12 -B. 
     A Calibrated mode area, which is a storage area assigned to the Partner calibrated mode in the parameter storage area M 1  is shared and used by a plurality of content viewing applications, for example. 
     For example, when the content viewing application  12 -A is starting-up, default image quality adjustment parameters are written once in the Calibrated mode area. A set of image quality adjustment parameters for the Partner calibrated mode for Service A obtained from the distribution server  2 - 1  is written to the Calibrated mode area in a form of overwriting the default image quality adjustment parameters stored earlier. 
     In a case where the Partner calibrated mode for Service A is set to on, image quality adjustment is performed on the basis of the image quality adjustment parameters for the Partner calibrated mode for Service A written at a time of starting-up, and on the basis of the Offset value for the Partner calibrated mode for Service A stored in the Offset storage area M 2 . 
     Similarly, when the content viewing application  12 -B is starting-up, the default image quality adjustment parameters are written once in the Calibrated mode area. A set of image quality adjustment parameters for the Partner calibrated mode for Service B obtained from the distribution server  2 - 2  is written to the Calibrated mode area in a form of overwriting the default image quality adjustment parameters stored earlier. 
     In a case where the Partner calibrated mode for Service B is set to on, image quality adjustment is performed on the basis of the image quality adjustment parameters for the Partner calibrated mode for Service B written at a time of starting-up, and on the basis of the Offset value for the Partner calibrated mode for Service B stored in the Offset storage area M 2 . 
     A business operator of each distribution service can set any kind of image quality adjustment parameters as image quality adjustment parameters for the Partner calibrated mode. That is, the types of image quality adjustment parameters included in the set of image quality adjustment parameters for the Partner calibrated mode may differ for each distribution service. 
     By allowing the image quality adjustment parameters to be written in a form of overwriting after the default image quality adjustment parameters are written once, the default image quality adjustment parameters can be used for image quality adjustment, for image quality adjustment parameters that are not included in the set. 
     Here, consider a case where the user can adjust the image quality adjustment parameters of the Partner calibrated mode such as the Brightness and the Color in accordance with his/her preference, and image quality adjustment parameters after the adjustment are written to the Calibrated mode area by the content viewing application. In this case, after information in the Calibrated mode area is reset once, user&#39;s setting contents are also reset. 
     By causing the Offset value for each distribution service to be stored in the Offset storage area M 2 , which is a non-volatile storage area, and making the image quality adjustment to be performed using the image quality adjustment parameters written at a time of starting-up and the Offset value, it becomes possible to perform image quality adjustment to reflect user&#39;s setting contents. 
     The image quality adjustment parameters in the Partner calibrated mode include parameters that include multiple sub-parameters, such as for a standard dynamic range (SDR)/for a high dynamic range (HDR)/for a Dolby Vision HDR/ . . . . For example, in a case where a content to start reproduction is the SDR content, the sub-parameters for the SDR are used, and HDR sub-parameters are used in a case of the HDR content. 
     At a time of writing image quality adjustment parameters to the parameter storage area M 1 , multiple sub-parameters are collectively acquired from the distribution server  2  regardless of the type of the content to start reproduction, such as SDR/HDR, and are written to the parameter storage area M 1 . In a case where the content to start reproduction is the SDR content, the HDR sub-parameters are to be parameters prepared in advance for when the type is switched. 
     Other 
     In a case where the Partner Offset is set by the user, a log showing setting contents may be transmitted to the distribution server  2 . 
     In this case, an Offset value of the Partner Offset set in a case where the Partner calibrated mode for Service A is on is transmitted to the distribution server  2 - 1  by the content viewing application  12 -A. 
     Furthermore, an Offset value of the Partner Offset set in a case where the Partner calibrated mode for Service B is on is transmitted to the distribution server  2 - 2  by the content viewing application  12 -B. 
     Configuration Example of Computer 
     The series of processes described above can be executed by hardware or software. In a case of executing the series of processes by software, a program that forms the software is installed from a program recording medium to a computer incorporated in dedicated hardware, to a general-purpose personal computer, or the like. 
       FIG. 23  is a block diagram showing a configuration example of hardware of a computer that executes the series of processes described above in accordance with a program. 
     A central processing unit (CPU)  1001 , a read only memory (ROM)  1002 , and a random access memory (RAM)  1003  are mutually connected by a bus  1004 . 
     The bus  1004  is further connected with an input/output interface  1005 . The input/output interface  1005  is connected with an input unit  1006  including a keyboard, a mouse, and the like, and an output unit  1007  including a display device, a speaker, and the like. Furthermore, the input/output interface  1005  is connected with a storage unit  1008  including a hard disk, a non-volatile memory, and the like, a communication unit  1009  including a network interface and the like, and a drive  1010  that drives a removable media  1011 . 
     In the computer configured as described above, the series of processes described above are performed, for example, by the CPU  1001  loading a program recorded in the storage unit  1008  into the RAM  1003  via the input/output interface  1005  and the bus  1004 , and executing. 
     The program to be executed by the CPU  1001  is provided, for example, by being recorded on the removable media  1011  or via wired or wireless transfer media such as a local area network, the Internet, and digital broadcasting, to be installed in the storage unit  1008 . 
     Note that the program executed by the computer may be a program that performs processing in a time series according to an order described in this specification, or may be a program that performs processing in parallel or at necessary timing such as when a call is made. 
     In this specification, the system means a set of a plurality of components (a device, a module (a part), and the like), and it does not matter whether or not all the components are in the same housing. Therefore, a plurality of devices housed in separate housings and connected via a network, and a single device with a plurality of modules housed in one housing are both systems. 
     The effects described in this specification are merely examples and are not limited, and other effects may also be present. 
     The embodiment of the present technology is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present technology. 
     For example, the present technology can have a cloud computing configuration in which one function is shared and processed in cooperation by a plurality of devices via a network. 
     Furthermore, each step described in the above-described flowchart can be executed by one device, and also shared and executed by a plurality of devices. 
     Moreover, in a case where one step includes a plurality of processes, the plurality of processes included in the one step can be executed by one device, and also shared and executed by a plurality of devices. 
     Combination Example of Configuration 
     The present technology can have the following configurations. 
     (1) 
     An image processing apparatus including: 
     a display control unit that controls to display an image quality adjustment menu including display related to setting of an image quality adjustment mode for a specific distribution service, in a case where an instruction is made to perform image quality adjustment during execution of an application that is used for viewing a content distributed by the specific distribution service.
