Description

  The present invention relates to image quality adjustment of a display.

  Conventionally, TV receivers are equipped with image quality adjustment functions as standard, and users can adjust image quality adjustment items (brightness, contrast, color density, sharpness, color temperature, memory color, etc.) prepared in advance. By doing so, it is possible to adjust to the desired image quality. In the case of a broadcast program, the image quality adjustment operation is performed while watching the program being viewed. In the case of a recording / playback device such as a DVD or a hard disk, the image quality adjustment operation is performed while the recorded video is played back and displayed. The optimum image quality is set by repeating the adjustment.

  Such an image quality adjustment operation is generally a cumbersome operation, and it is often a heavy burden on the user to repeat this operation for each viewing. Therefore, various measures are taken into consideration in order to reduce the burden on the user.

Among products that are currently commercialized, once set image quality adjustment values are preset in non-volatile memory, and the user can select the preset information manually and restore the adjustment values at any time. There is something. Patent Document 1 discloses a method of associating an input video source (TV tuner, car navigation system, VTR, etc.) with an image quality adjustment value and storing them in a preset memory. Further, Patent Document 2 discloses a method of associating program information that can be acquired from broadcasting and an image quality adjustment value in association with each other in a preset memory. In either case, the adjustment value can be automatically restored if the user matches the condition associated with the adjustment value without manually selecting preset information.

  In the case of car navigation, almost a specific individual user often uses the car exclusively. Also, in analog broadcasting television viewing styles in ordinary homes, there are many cases where only one person in the family is particular about image quality adjustment. The prior art can be said to be a suitable means when applied to such a specific user for the purpose of reducing the burden of image quality adjustment.

  Recently, however, high-definition and high-definition video can be enjoyed at home by digitalization of broadcasting, and a large screen such as a flat panel (liquid crystal, PDP) can be used in parallel with the flow. With the development of high-resolution, high-definition, and high-quality images, general users are increasingly interested and interested in image quality. For this reason, it is expected that the number of cases in which a plurality of users will adjust the image quality of their choice to future TV viewing styles in the future will increase. Accordingly, even in such an environment, the adjustment value once set is unexpectedly changed by another user, so that further improvement is required so as to eliminate the trouble of readjustment.

In addition, due to the recent spread of home appliances such as hard disk recorders, large screen displays are installed in living rooms, small displays are installed in rooms such as bedrooms, and video on each display is distributed from a common video home server. Is expected to be used. As a result, it is expected that the viewing style will change to a viewing location that is selected according to the life scene and viewed on a plurality of displays, instead of viewing the video on a single display as before.

  Different types of displays have different luminance characteristics, light emission characteristics, luminance, color reproduction ranges, and the like. For example, an adjustment value adjusted on a living room display may be too bright on a bedroom display. Even if the type of display is the same, the living room is bright and adjusted to increase the brightness. However, in the bedroom, the room is often darkened, so there are differences such as wanting to reduce the brightness further.

  In other words, the image quality adjustment value in the multiple display environment as described above is important as to which “adjustment” is adjusted for “what image” while watching “which display”. There is a demand for an image quality adjustment method that can cope with changes in the viewing style depending on the life scene.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to automatically improve image quality in accordance with each user's preference and viewing environment in an environment where a plurality of displays are shared by a plurality of users. An object of the present invention is to provide an image quality adjustment apparatus and a display system that can be adjusted.

  An image quality adjustment apparatus according to an aspect of the present invention is an image quality adjustment apparatus that can be connected to a plurality of displays, and includes a user ID for specifying a user, a display ID for specifying a display, and an image quality adjustment of the display. Storage means capable of storing a plurality of image quality adjustment profiles associated with the image quality adjustment information used in the process, ID acquisition means for acquiring a user ID of a user who wants to view the display and a display ID of the viewing target display, An image quality adjustment profile including a user ID and a display ID that match the ID acquired by the ID acquisition unit is read from the storage unit, and an image quality adjustment process for the viewing target display based on the image quality adjustment information included in the image quality adjustment profile And processing means for executing.

  In addition, a display system according to an aspect of the present invention includes a plurality of displays and an image quality adjustment device connected to the plurality of displays, and the image quality adjustment device includes a user ID for identifying a user, Storage means capable of storing a plurality of image quality adjustment profiles associating a display ID for specifying a display and image quality adjustment information used for image quality adjustment of the display, a user ID of a user who wants to view the display, and its viewing An ID acquisition unit that acquires the display ID of the target display, and an image quality adjustment profile that includes a user ID and a display ID that match the ID acquired by the ID acquisition unit are read from the storage unit and included in the image quality adjustment profile The viewing target data is based on the image quality adjustment information. And a processing unit for executing image quality adjustment processing on the display.

  According to the present invention, when a user tries to view a display, an appropriate image quality adjustment process corresponding to the user and the display is executed. Therefore, even in an environment in which a plurality of users share a plurality of displays, it is possible to automatically adjust the image quality according to each user's preference and viewing environment.

  Exemplary embodiments of the present invention will be described in detail below with reference to the drawings.

<First Embodiment>
FIG. 1 is a functional block diagram of a display system according to the first embodiment of the present invention.

  This display system is roughly composed of three blocks: a receiving device 1, a first display device 9, and a second display device 15. The receiving device 1 has a function as a server device that distributes a video signal broadcast from a broadcasting station or a video signal input from the recording / playback unit 21 to at least one display device (display). The receiving device 1 also has a function as an image quality adjusting device that adjusts the image quality displayed on the display device. The first display device 9 and the second display device 15 have a function as a display device that displays the video signal distributed from the receiving device 1. The first display device 9 and the second display device 15 may be different types of displays (for example, the first display device 9 is a PDP (Plasma Display Panel) and the second display device 15 is an LCD (Liquid Crystal Display)).

  In this embodiment, the receiving device 1, the first display device 9, and the second display device 15 are installed in physically separated rooms (for example, the receiving device 1 and the first display device 9 are a living room, a second display device). 15 is assumed to be a system such as a so-called master unit or slave unit television system. The number of display devices is not limited to two and may be one or more than two.

(Receiver)
First, the configuration of the receiving device 1 will be described.

  The receiving device 1 receives BS / CS / terrestrial digital broadcasting with an antenna 2. In this embodiment, digital broadcasting is illustrated, but a video signal may be received from an analog terrestrial wave, an optical cable, or the like.

  The channel selection units 31 and 32 pass the broadcast signal through a bandpass filter, a down converter, etc., and then perform demodulation processing that matches the transmission type of the broadcast type, and also perform error correction processing, etc. , TS). This TS is delivered to the demultiplexing units 41 and 42.

  The demultiplexing units 41 and 42 separate MPEG2 video data, MPEG2 audio data, and additional information of a desired program from the TS.

  The separated MPEG2 audio data is decoded by an audio decoder (not shown) and output as an audio signal. If you connect an amplifier or speaker to this output terminal, you can listen to the audio of the received program.

  The separated MPEG2 video data is decoded by video processing units 51 and 52 and converted into a raster scan baseband display format. Furthermore, the video data is subjected to processing such as resolution conversion and I / P conversion according to the resolution of the display device as a broadcast video source, and then delivered to the image quality adjustment units 61 and 62.

The additional information separated by the demultiplexing units 41 and 42 is transferred to the system control unit 8 through the signal line S0. When the additional information is data broadcasting operated by BS digital broadcasting, the system control unit 8 interprets BML (Broadcast Markup Language) script language,
A content scenario of a multimedia information service provider can be obtained. When the additional information is EPG (Electrical Program Guide) information, the system control unit 8 interprets PSI (Program Specific Information) / SI (Service Information; program arrangement information) and program information (for example, program information). , Metadata representing information about video such as broadcast time, title, category, etc.).

  The image quality adjustment units 61 and 62 of the receiving device 1 are image quality adjustment means for executing image quality adjustment processing on video data. In the image quality adjustment units 61 and 62, image quality adjustment items such as brightness, contrast, color density, sharpness, color temperature, and memory color are prepared, and flexible image quality adjustment is possible according to the user's preference. is there.

  The system control unit 8 is a control means for controlling the entire system, and has a CPU having computing power, a RAM for temporarily storing data, a ROM for storing a control program, a counter for measuring time, a peripheral input / output interface and the like (Both not shown). Further, the system control unit 8 may be composed of only logic logic, or may be a CPU or a media processor capable of parallel operation. The control program may be built in the ROM or transferred from the outside via a peripheral input / output interface. The ROM stores character fonts and the like as necessary, and is used when expanding character information on the screen.

  The preset memory 7 is a storage device configured by a rewritable nonvolatile memory device such as a flash memory, and stores necessary system data even after the power is turned off.

  The recording / playback unit 21 includes a recording device such as a hard disk or a DVD, and can record / playback video signals (video data). Recording / reproduction of the video signal is controlled by the system control unit 8. At the time of recording, the system control unit 8 takes out the TS (PTS) to be recorded from the demultiplexing units 41 and 42 and writes the data to the recording / reproducing unit 21. At the time of reproduction, the system control unit 8 reads a reproduction target TS (PTS) from the recording / reproduction unit 21 and delivers the data to the video processing units 51 and 52.

  The two video signals from the receiving device 1 are distributed to the first display device 9 and the second display device 15 via the first and second display interfaces. The display interface may be unidirectional communication or bidirectional communication capable of command communication. Also, wired or wireless is not an issue.

(Display device)
Next, the configuration of the first display device 9 and the second display device 15 will be described.

  The video data distributed from the receiving device 1 is input to the display correction units 10 and 16. The display correction units 10 and 16 perform display-dependent signal processing (inverse gamma conversion, color conversion, color reproduction correction, gradation control, etc.) according to the characteristics of the display units 12 and 18. The output here is transferred to the display control units 11 and 17.

The display control units 11 and 17 perform drive control according to the type of the display units 12 and 18. The display units 12 and 18 are display panels, which are flat panels having a matrix electrode structure (LCD, PDP, FED (Field Emission Display), SED (Surface-conduction Electron-emitter Display, etc.)), CRT (Cathode Ray Tube). However, any device that can display an image is acceptable.

  The control units 13 and 19 are control means for controlling the entire first display device 9 and second display device 15. The control units 13 and 19 of the display device and the system control unit 8 of the receiving device 1 are connected by bidirectional communication lines S1 and S2. The control units 13 and 19 include a nonvolatile memory, and unique identification information for each display device is stored in the memory. The identification information of this display device is defined as “display ID”.

  The user identification units 14 and 20 are parts for identifying a user who intends to view (use) the display device. Various user identification methods can be employed. For example, a method for notifying a user identification unit 14 or 20 from a personal remote controller in which personal information is registered in advance, a UI card (User Interface Card), an RF tag (Radio Frequency Tag), a mobile phone, or the like, or voice or fingerprint A user identification method based on biometrics information recognition, and a user login method generally used in a personal computer are assumed. Of course, the present invention is not limited to these, and any other method may be adopted as long as the user who wants to view the display device can be specified. Note that identification information for identifying a user such as personal information, biometric information, and a login ID is defined as a “user ID”.

(Image quality adjustment processing)
Hereinafter, image quality adjustment processing in the display system will be described with reference to the flowchart of FIG.

  A user who wants to view a display device first logs in to the display device to be viewed (hereinafter, the case of viewing the first display device 9 will be described). Specifically, when the user gives a login request to the first display device 9, the control unit 13 reads its own display ID from the memory (step S100), and controls the user identification unit 14 to The user ID is acquired by such an identification method (step S101). The login request is given, for example, when the user operates a switch such as a display device or a remote controller to turn on display on the display device or input an explicit login request.

  In step S102, the control unit 13 notifies the system control unit 8 of the receiving device 1 of the display ID and the user ID through the bidirectional communication line S1. Thereby, the system control unit 8 of the receiving device 1 can acquire the user ID of the user who wants to view the first display device 9 and the display ID of the first display device 9 that is the viewing target. That is, in this embodiment, the system control unit 8 corresponds to the ID acquisition unit of the present invention.

  Next, when the user selects viewing media on the first display device 9, the control unit 13 transmits a selection signal to the system control unit 8 through the bidirectional communication line S1 (step S103). When the viewing media is a broadcast system, the system control unit 8 switches the broadcast program by tuner control of the channel selection unit 31 and distributes the video signal of the selected program to the first display device 9. As a result, the broadcast video is displayed on the first display device 9.

  When the user operates the first display device 9 or a switch on the remote controller to make an image quality adjustment request, the control unit 13 transmits an image quality adjustment request signal to the system control unit 8 through the bidirectional communication line S1. When receiving the image quality adjustment request signal (step S104: YES), the system control unit 8 synthesizes and outputs an image quality adjustment OSD (On Screen Display) screen to the video.

  The user can perform an image quality adjustment operation on the image quality adjustment OSD screen displayed on the first display device 9 (step S105). As described above, this image quality adjustment operation adjusts various image quality adjustment items such as brightness, contrast, color density, sharpness, color temperature, and memory color. When the image quality adjustment operation is finished, in step S106, it is confirmed whether or not the adjustment items are preset for the user. In the case of presetting, the system control unit 8 creates an image quality adjustment profile in step S107.

This image quality adjustment profile is information associated with at least a user ID for specifying a user, a display ID for specifying a display device, and an image quality adjustment value (image quality adjustment information) used for image quality adjustment of the display device. It is. Thus, the image quality adjustment value is managed together with the user ID and the display ID because it is important which user sets the image quality adjustment value on which display device. That is, the image quality adjustment profile can be prepared individually according to the user's preference, the viewing environment of the display device, the display characteristics of the display device, and the like.

  Further, in the present embodiment, the image quality adjustment value is managed in association with the video attribute (media attribute). This makes it possible to set different image quality adjustment values according to the content and type of video.

  A specific example of image quality adjustment profile management is shown in FIG. In this example, since digital broadcasting has been described as an example, the video attribute is a program category that can be acquired from the above-described SI information. However, the program title itself, and further, the time attribute when the image quality adjustment is performed (the viewing environment is It may be associated with the image quality adjustment due to the light place and dark place.)

  In step S108, the image quality adjustment profile is stored in the preset memory 7 in the structure table description as shown in FIG. In the example of FIG. 3, four image quality adjustment profiles are preset, and it can be seen that different image quality adjustment values are set according to combinations of the user, the display, and the media attributes. In the present embodiment, the preset memory 7 corresponds to the storage means of the present invention.

  The above image quality adjustment operation can be reset any number of times until the user logs out at the viewing location in step S109.

  Next, a process when image quality adjustment is automatically performed using a preset image quality adjustment profile will be described.

  The process for acquiring the user ID and the display ID and the process for selecting the viewing media are the same as steps S100 to S103 described above.

  If there is no image quality adjustment request from the user in step S104, the system control unit 8 executes automatic image quality adjustment processing. First, the system control unit 8 compares the user ID and display ID acquired in step S102 with the user ID and display ID of each image quality adjustment profile stored in the preset memory 7 (step S110).

  Here, if there is no image quality adjustment profile with the matching ID (step S111: NO), the system control unit 8 reads a default adjustment value stored in advance in the preset memory 7, and sends the adjustment value to the image quality adjustment unit 61. hand over. The image quality adjustment unit 61 performs image processing on the video signal from the video processing unit 51 based on (and therefore) the received default adjustment value. In this way, the default adjustment value is reflected in the video of the first display device 9 (step S114).

  On the other hand, when there is an image quality adjustment profile with the matching ID (step S111: YES), the system control unit 8 includes information included in the metadata attached to the viewing target program (video signal), and the image quality adjustment profile. It is determined whether or not the media attributes match (step S112). In the example of FIG. 3, the SI information of the currently selected broadcast program is acquired and compared with the SI information preset in the media attribute of the image quality adjustment profile.

If the media attributes match (step S112: YES), the system control unit 8 passes the image quality adjustment value included in the image quality adjustment profile to the image quality adjustment unit 61. The image quality adjustment unit 61 performs image processing on the video signal from the video processing unit 51 based on (and therefore) the received image quality adjustment value. In this way, the image quality adjustment value set by the user is reflected in the video of the first display device 9 (step S113), and the user's favorite image quality is restored.

  On the other hand, if the media attributes do not match (step S112: NO), the system control unit 8 reflects the default adjustment value as described above (step S114).

  In the present embodiment, the system control unit 8 and the image quality adjustment unit 61 (62) correspond to the processing means of the present invention.

  According to the present embodiment described above, when a certain user tries to view a display device, the image quality adjustment value set in the past by the user on the display device is automatically reflected. Therefore, even in an environment where a plurality of users share a plurality of display devices, it is possible to automatically adjust the image quality according to each user's preference and viewing environment.

  In addition, since the image quality adjustment is controlled by matching the user ID, an adjustment value set by another user is reflected in error, or the adjustment operation for the user is performed again after viewing by another user. The user can be freed from such annoyance.

  Further, in the present embodiment, since the image quality adjustment value and the video attribute (media attribute) are associated with each other, the optimum image quality adjustment can be automatically switched according to the content and type of the viewing target video.

<Second Embodiment>
In the first embodiment, an example in which the image quality adjustment method of the present invention is applied to a broadcast video has been described. In the second embodiment, an example in which the video image adjustment method is applied to a playback video from a recording / playback apparatus will be described. In addition, about the part which is common in the thing of 1st Embodiment, such as a structure of a display system, the detailed description is abbreviate | omitted using the same code | symbol.

(Image quality adjustment processing)
Hereinafter, image quality adjustment processing in the display system of this embodiment will be described with reference to the flowchart of FIG. (Since there are some steps common to the first embodiment, the difference will be described below.)

  When the user logs in to the first display device 9, the system control unit 8 obtains the display ID and the user ID through the bidirectional communication line S1 in steps S100 to S102.

  Next, when the user selects viewing media on the first display device 9, the control unit 13 transmits a selection signal to the system control unit 8 through the bidirectional communication line S1 (step S103). When the viewing media is a recording / reproducing device, the system control unit 8 reproduces the video of the recording / reproducing unit 21 and distributes the reproduced video to the first display device 9. As a result, the reproduced video is displayed on the first display device 9.

  If there is an image quality adjustment request from the user, the image quality adjustment operation is performed in steps S104 to S105, and the adjustment items are preset for the user in step S106, as in the first embodiment. Check whether or not. In the case of presetting, the system control unit 8 creates an image quality adjustment profile in step S107.

  The management method of the image quality adjustment profile here is different from the management method of the first embodiment. Specifically, while the media attribute is included in the image quality adjustment profile in the first embodiment, the image quality adjustment profile that does not include the media attribute is managed in association with the video signal. This is because, unlike the broadcast video, the video during playback is always the same.

  Further, in the first embodiment, the image quality adjustment profile is stored in the preset memory 7, whereas in the present embodiment, the image quality adjustment profile is embedded in the video signal and stored in the recording / playback unit 21 together with the video signal (Step S1). S108). That is, in the present embodiment, the recording / reproducing unit 21 corresponds to the storage unit of the present invention.

  FIG. 4 shows an example of the image quality adjustment profile. In the example of FIG. 4, a user area is defined by expanding a header in a normal video data area, and a user ID, a display ID, and an image quality adjustment value associated with the user area are embedded as an image quality adjustment profile. A plurality of image quality adjustment profiles can be embedded in one video signal (video data area) (two are embedded in FIG. 4).

  The video data recorded in the recording / playback unit 21 can record a plurality of video data for each program and each scene. Therefore, when there are a plurality of video data areas, a user area may be provided for each video accordingly, and an image quality adjustment profile may be embedded in each user area.

  The above image quality adjustment operation can be reset any number of times until the user logs out at the viewing location in step S109.

  Next, a process when image quality adjustment is automatically performed using an image quality adjustment profile embedded in a video signal will be described.

  If there is no image quality adjustment request from the user in step S104, the system control unit 8 executes automatic image quality adjustment processing. First, the system control unit 8 acquires the user ID and display ID acquired in step S102, and the user ID and display ID of each image quality adjustment profile embedded in the video signal to be viewed (read from the recording / playback unit 21). Are compared (step S110).

  Here, if there is no image quality adjustment profile with the matching ID (step S111: NO), the system control unit 8 performs image quality adjustment based on the default adjustment value stored in advance in the preset memory 7, and reproduces the video. (Step S114).

  On the other hand, if there is an image quality adjustment profile with the matching ID (step S111: YES), the system control unit 8 passes the image quality adjustment value included in the image quality adjustment profile to the image quality adjustment unit 61. The image quality adjustment unit 61 performs image processing on the video signal from the video processing unit 51 based on (and therefore) the received image quality adjustment value. In this way, the image quality adjustment value set by the user is reflected in the reproduced video on the first display device 9 (step S113), and the user's favorite image quality is restored.

  Even with the configuration of the present embodiment described above, the same operational effects as those of the first embodiment can be obtained. Moreover, according to the present embodiment, the image quality adjustment method can be applied not only to broadcast video but also to playback video from a recording / playback apparatus.

In general, image quality adjustment to a recorded video is performed by a user performing an editing operation and writing it again on a recording medium such as a DVD with the image quality adjustment performed. In this case, only data whose image quality has been adjusted can be reproduced at the next reproduction. For this reason, when performing different image quality adjustments for each user, it is necessary to prepare a plurality of recording media for each user, or when you want to redo image quality adjustment later, back up the original data to another storage medium. An inconvenient problem arises that must be kept.

  On the other hand, according to the present embodiment, since the image quality adjustment profile is embedded in the user area of the video signal, the original data remains as it is, and an adjustment value is added for each user, and the adjustment can be repeated many times later. Changes can be made. Thereby, there is an advantage that sharing of image quality adjustment values of a plurality of users can be realized with only one recording medium.

It is a functional block diagram of a display system. It is a flowchart of an image quality adjustment process. It is an example of the image quality adjustment profile for broadcast video. It is an example of an image quality adjustment profile for a recorded video.
