[Operation of control unit]
Operations relating to image quality and user settings of the main control unit 100 included in the display device 10 according to the present embodiment will be described below with reference to FIGS. FIG. 2 is a flowchart showing a flow of processing relating to image quality and user settings of the main control unit 100 included in the display device 10 according to the present embodiment.

(Image quality / user setting process)
As shown in FIG. 2, when notified to display a menu screen for setting image quality adjustment values, the image quality setting unit 120 displays a selection screen for selecting whether or not to perform simple settings on the display unit 23. (Step S1). If it is selected to perform easy setting (YES in step S1), an operation of “easy setting” by the user is accepted (step S2).

  Here, “easy setting” means displaying on the display unit 23 a sample image whose image quality has been adjusted based on a plurality of pieces of image quality information (image quality adjustment settings previously applied to the sample image in order to make simple settings). In this setting method, the image quality adjustment value is set based on the image quality information of one image selected by the user from a plurality of sample images. By presenting the sample image in this way, the user can intuitively select a favorite image.

  More specifically, in the present embodiment, three sample images are presented for each genre and performed for three types of genres. The three types of genres are “film”, “video”, and “sports”. “Film” indicates that the content originates from a film, and is a content genre obtained by performing 3: 2 pull-down processing on content shot at 24 Hz. “Video” is a genre of content derived from normal broadcasting of 60 Hz. “Sports” is a genre of content associated with genre information of sports by EPG data. The sample images are adjusted with different patterns. The genre information is not limited to “video”, “film”, and “sports”, but “news / report”, “information / wide show”, “variety”, “movie”, etc. You may comprise so that various genres can be identified.

  In the three types of sample images, color saturation, sharpness, and gamma are adjusted from pattern 1 to pattern 3, and the three sample images processed in patterns 1 to 3 are displayed for each genre. . The image quality setting unit 120 records the three pieces of image information selected one by one for each genre among the three types of displayed sample images in association with the genre information and records them in the recording unit 21.

  In the example described here, the pattern 2 is a pattern recommended by the manufacturer that performs standard image quality adjustment, the pattern 1 is a pattern that performs so-called “smooth” image quality adjustment, and the pattern 3 is so-called “rich”. This pattern performs image quality adjustment. “Slightly” means, for example, that the color tone is gentle in terms of color saturation, and that the contour is more ambiguous and gentle in terms of sharpness. This means that it is straight or the S-shaped characteristic is weaker. In addition, the term “dull” means, for example, that the color saturation is more vivid in terms of color saturation, and that the contour is more emphasized in terms of sharpness (0 is the initial value). The greater the value of +, the stronger the sharpness.) In terms of gamma, it means that the S-characteristic is stronger.

  In the above description, the sample image is presented in the simple setting. However, instead of the sample image, “color saturation is (1) light, (2) normal, (3) You may display an explanatory note such as "Which one will you choose?" In this way, at the time of simple setting, an image or an explanatory text adjusted with candidate image quality information may be displayed.

  When it is selected not to perform simple setting (NO in step S1), an operation of “professional setting” by the user is accepted (step S3). Here, the “professional setting” is a setting method in which the user himself / herself sets a finer image quality adjustment value than the simple setting according to the user's preference. That is, this setting is for users who have more detailed knowledge about image quality.

  When you select the target genre for professional settings, an adjustment bar for adjusting the brightness level, black level, color depth, hue, and sharpness is displayed on the screen for adjusting the image quality parameters. Send instructions to adjust each parameter. The image quality setting unit 120 records the set parameter values (image quality adjustment values) in the recording unit 21 in association with the genre information. In this embodiment, the brightness level, the black level, the color density, the hue, and the sharpness are described as parameters for adjusting the image quality. However, the present invention is not limited to these. In this embodiment, the configuration in which the professional setting is performed when the simple setting is not performed has been described as an example, but the present invention is not limited to this. For example, after performing the simple setting, the professional setting is further performed. You may employ | adopt the structure to perform.

  After performing simple settings (step S2) or after performing professional settings (step S3), an operation for user registration is accepted (step S4). FIG. 3 shows an example of a user registration screen in the present embodiment. As shown in FIG. 3, the image quality setting unit 120 accepts input of a user name by operating the remote controller 30. Examples of the user name include father, mother, child 1, child 2, and the like, but are not limited thereto. The image quality setting unit 120 records the input user name in the recording unit 21 in association with the image quality adjustment value for each genre recorded in step S2 and step S3. Note that the configuration in which the image quality setting unit 120 receives an input of a user name has been described, but the present invention is not limited to this, and a configuration in which a preset user name is selected may be used.

  FIG. 4 shows an example of image information set for each user by simple setting. As shown in FIG. 4, the recording unit 21 records the user set in step S4, and three sample images for each of the three types of genres set in step S2 associated with each user. One of them is recorded.

  FIG. 5 shows an example of image quality adjustment values set for each user by professional settings. As shown in FIG. 5, the user set in step S4 is recorded in the recording unit 21, and image quality adjustment values for each of the three types of genres set in step S3 associated with each user are recorded. Has been.

(User-specific processing)
An operation related to user-specific processing of the main control unit 100 included in the display device 10 according to the present embodiment will be described below with reference to FIG. FIG. 6 is a flowchart showing a flow of processing relating to user identification in the main control unit 100 included in the display device 10 according to the present embodiment.

  As shown in FIG. 6, when the user selection screen display instruction is acquired, the user specifying unit 130 displays the user selection screen on the display unit 23 (step S11). On the user selection screen, for example, user names of users who have set image quality adjustment values may be displayed as a list, or a screen as shown in FIG. 3 may be displayed. The content displayed on the user setting screen is not limited to this.

  When the user selection screen is displayed, the user specifying unit 130 acquires a user selection signal that selects the user name of the user who uses the display device 10 from the displayed user names (step S12).

  When the user selection signal is acquired, the image quality adjustment instruction unit 150 acquires the user name of the user selected from the user specifying unit 130, and reads the image quality adjustment value recorded in association with the acquired user name from the recording unit 21. . The image quality adjustment instruction unit 150 adjusts the video signal input to the display device 10 based on the image quality adjustment value set for the genre information acquired from the genre acquisition unit 140 among the read image quality adjustment values. Thus, the image quality adjustment unit 22 is notified (step S13).

(When multiple users view)
Although the case where there is only one user who watches a program has been described as an example, a case where a plurality of users view a program at the same time is also assumed. For example, the case where a user who watches a program at the same time is a father, a mother, and a child 1 will be described below with reference to FIGS.

  FIG. 7 is a diagram illustrating an example of a value obtained by averaging image information of sample images selected by each user for each genre in the simple setting. FIG. 7A is a diagram showing the weights set for the sample images selected by each user for each genre in the simple setting, and FIG. 7B is an image selected by each user for each genre. FIG. 7C is a diagram illustrating the setting of the image quality adjustment value when the average value does not become an integer.

  When a plurality of users are watching a program, the image quality adjustment value of each genre is determined by averaging the image quality adjustment values set by the plurality of users. As shown in (a) of FIG. 7, weights are set for the images selected by each user in the simple setting. For example, a weight of 1.0 is set for image 1, 2.0 for image 2, and 3.0 for image 3. In addition, the father selects image 3 among the sample images for setting the image quality adjustment value for sports, image 1 for video, and image 1 for film. The mother selects image 3 for sports, image 2 for video, and image 3 for film, and the child 1 selects image 3 for sports, image 2 for video, and image 2 for film.

  As shown in FIG. 7B, when a plurality of users watch a program at the same time, an image quality adjustment value is determined by averaging the weight of the image selected by each user in the simple setting for each genre. To do. Among the three types of genres, since the image 3 is selected by three users for the sample image relating to sports, the average value of the image weights is 3.0. That is, when the father, mother, and child 1 watch a program whose genre information is sports at the same time, image quality adjustment is performed based on the image quality information of the image 3.

  In the sample image whose genre information is film, the image 1 is selected by the father, the image 2 is selected by the mother, and the image 2 is selected by the child 1. Therefore, the average value of the image weights is 2.0. That is, when the father, the mother, and the child 1 simultaneously view a program whose genre information is a film, the image quality adjustment is performed based on the image quality information of the image 2.

  Further, in the sample image whose genre information is video, since the image 1 is selected by the father, the image 3 is selected by the mother, and the image 2 is selected by the child 1, the average value of the image weights is about 1.6. Since there is no sample image with the weight set to 1.6, as shown in FIG. 7C, when the father, the mother, and the child 1 watch a program whose genre information is video at the same time. The image quality adjustment value is set between the set values of the image quality information of the image 1 and the image quality information of the image 2 based on a value close to the image quality information of the image 2 by about 60% from the image quality information of the image 1.

  Note that, when a plurality of users are watching a program, the image quality adjustment value of each genre is determined by averaging the image quality adjustment values set by the plurality of users, but the present invention is not limited to this. Of the image quality adjustment values set by the user, the image quality adjustment value that is set most frequently may be used as the image quality adjustment value for each genre.

  FIG. 8 is a diagram in which the most frequently selected sample images are selected from the sample images selected for each genre by each user in an example of simple setting. FIG. 8A is a diagram showing sample images selected by each user for each genre in simple setting, and FIG. 8B is a diagram in which the most frequently set sample images are selected. .

  As shown in FIG. 8A, the dad has selected image 3 among sample images for setting sports image quality adjustment values, image 1 for video, and image 1 for film. Also, the mother selects image 3 for sports, image 2 for video, and image 3 for film, and the child 1 selects image 3 for sports, image 2 for video, and image 2 for film.

  As shown in FIG. 8B, when a plurality of users watch a program at the same time, an image selected most frequently among images selected by each user in an easy setting is set as an image for each genre. Determine the image quality adjustment value. Among the three types of genres, the image 3 is selected by the three users, so that the most frequently selected image is the image 3. That is, when the father, mother, and child 1 watch a program whose genre information is sports at the same time, image quality adjustment is performed based on the image quality information of the image 3.

  In addition, the sample image whose genre information is film is image 1 selected by the father, image 2 by the mother, and image 2 by the child 1, so the most frequently selected image is image 2.
