Therefore, the burden on the user is extremely small, and the image quality switching of the display device according to the application software can be very easily performed.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of an image display system including a display device and a computer according to an embodiment of the present invention.
This embodiment corresponds to claims 7 and 19 of the present invention.

  The image display system includes a display device 1 that is a device that displays an image, and a computer 3 that outputs a signal related to the image to the display device 1. The display device 1 includes, for example, a CRT 5, and an image is displayed by a signal from the video circuit 7. The video circuit 7 is connected by a video cable 8 to a graphic controller 21 built in the computer 3 described later, and operates based on the output signal.

  The graphic controller 21 includes a graphic card mounted in an expansion slot or the like of the computer 3 in addition to the one built in the computer 3.

  A memory 9 corresponding to the first storage means of the present invention stores parameters for adjusting the image quality by controlling the video circuit 7 described above. Specifically, a parameter table in which image quality modes and parameters are associated in advance is stored so that the image quality on the display device 1 is appropriate. Although details regarding the parameter table will be described later, specifically, the parameter table is as shown in the schematic diagram of FIG.

  A USB cable 12 connected to the computer 3 is connected to the USB controller 11 corresponding to the communication interface in the present invention. The USB controller 11 is mainly used for communication with the computer 3.

  The control unit 13 determines an image quality mode of application software (hereinafter referred to as an active application) that is executed by the computer 3 and selected and activated by the user.

  Specifically, the image quality mode of the active application is acquired from the USB controller 11. Then, the corresponding parameter is extracted based on the parameter table stored in the memory 9 and the image quality mode, and the video circuit 7 is adjusted with the parameter.

  The control unit 13 corresponds to the control means in the present invention.

  The computer 3 includes a CPU 15, a memory 17, a hard disk 19, and a graphic controller 21, which are connected via a bus 23.

  A program that is read from the hard disk 19 and executed is resident in the memory 17. Further, the image quality mode table (see FIG. 3) is read from the hard disk 19 as necessary. The program performs association and setting in the image quality mode table, recognizes which of the plurality of application software programs executed on the computer 3 has been selected by the user, and determines the image quality mode. To work.

  The hard disk 19 stores an operating system, various programs, and an image quality mode table.

  The CPU 15 corresponds to the determination unit of the present invention, and the memory 17 corresponds to the second storage unit of the present invention.

  The parameter table stored in the memory 9 is configured, for example, as shown in the schematic diagram of FIG. That is, the data is in table format in which nine types of image quality modes are associated with parameters for adjusting the video circuit 7. These associations are set in advance at the time of factory adjustment. Also, the user can freely set it according to his / her preference.

  In this embodiment, nine image quality modes are set as an example. Specifically, Text, Browser, Picture, Graphic, sRGB, Movie1, Movie2, Movie3, Movie4.

  The “Text” mode is a standard screen display, is an image quality mode suitable for writing or reading a sentence, and is mainly suitable for a word processor or the like. The “Browser” mode is a screen display with a slightly enhanced contrast correction, and is an image quality mode suitable for displaying a screen such as a browser where text and photographs are mixed. The “Picture” mode increases the brightness to increase the contrast. This is a screen display with enhanced correction, and is an image quality mode suitable for still images such as photographs.

  The “Graphic” mode is a bright screen display with increased brightness without contrast enhancement correction, and is suitable for animations and illustrations. The “sRGB” mode is a screen display corresponding to Windows standard sRGB, the color temperature is fixed at 6500K, and the color environment can be standardized with other devices such as a printer, which is suitable for printing.

  “Movie1” mode is a bright screen display with high brightness and contrast enhancement correction, suitable for full-screen movies such as DVD and TV. “Movie2” mode is a bright screen display with high brightness and contrast enhancement correction. Suitable for standard size display of movies such as DVD and TV, “Movie3” mode is a screen display with high brightness and no contrast enhancement correction, sharpness is applied, and “Movie4” mode is high brightness and contrast enhancement The screen display is not corrected and sharpness is not applied.

  The above nine types of image quality modes include parameters such as contrast, brightness, color temperature, gamma value 1 which is a low gradation part gamma, and gamma 2 which is a gamma value of an intermediate gradation part. , And contour correction. Some of these parameters are set in advance as default values, and others are configured so that the user can appropriately set them.

  It is not necessary to set all the parameters described above, and only one of them may be set.

  The image quality mode table stored in the memory 17 is configured as shown in the schematic diagram of FIG. 3, for example. That is, the table is a table in which the nine types of image quality modes described above and image quality adjustment values for adjusting the graphic controller 21 are associated with application software. These associations are performed in advance by the user as necessary.

  In this example, “Text” mode is associated with “word processor” of application software, “Text” mode is associated with “Spreadsheet”, “Graphic” mode is associated with “Retouch”, and “Video playback” is associated with The “Window Movie” mode is associated. As the “word processor”, for example, a Microsoft word is representative, and as the “spreadsheet”, Microsoft Excel is typical. “Retouch” is typically Adobe Photoshop, and “movie playback” is typically Microsoft Windows Media Player.

  The “Window Movie” mode is different from other image quality modes and is associated with “Movie 1” or “Movie 2” of the image quality mode in the parameter table of FIG.

  Examples of the image quality adjustment value set in the image quality mode table include a gamma value and a resolution. In general, there is little need to change these in the Text mode and the Graphic mode, and the default is often left. That is, the gamma values of symbols γ-1 to γ-3 and the resolution of symbols R-1 to R3 in FIG. 3 are often default values.

  On the other hand, these settings are useful in the “Window Movie” mode. For example, it is preferable to set the gamma value γ-4 in FIG. 3 to be lower than the default to lower the luminance. The resolution R-4 is preferably set to a value suitable for viewing.

  The graphic controller 21 outputs a signal related to drawing to the video circuit 7 of the display device 1 based on an instruction of the operating system executed in the memory 17. At that time, the image quality mode table is referred to, and the image quality adjustment value is reflected on the graphic controller 21. However, the gamma value is not reflected only in the area where the moving image is displayed. This function is generally referred to as “overlay”, and many graphic controllers and graphic cards on the market today have this function.

  Next, the operation of the above-described image display system will be described with reference to the flowchart of FIG. 4 showing the main part of the operation of the image display system.

  In the computer 3, it is assumed that a plurality of application software is already executed by the user. The processing described below shows the main part of the processing from when application software is switched, and the following processing is executed each time switching is performed.

Step S1
For example, the operating system (hereinafter referred to as OS) recognizes the application software selected by the user selecting one of the windows using a pointing device such as a mouse (not shown), that is, the active application. In response, the program determines the image quality mode of the active application.

  The recognition of the active application and the determination of the image quality mode are performed as follows, for example. The case where the OS is Windows will be described as an example.

  First, the OS acquires a window handle (hereinafter referred to as AH) of the active application, and acquires a process ID (hereinafter referred to as AID) of the active application using this AH. Next, a list of process IDs of application software activated on the OS (IDs for managing programs being executed by the OS) is acquired. Then, a list of application software processes (hereinafter referred to as CP) running on the OS is acquired.

  Next, a process ID (hereinafter referred to as CID) is acquired from the CP, and it is determined whether or not the AID and the CID match. If they match, the execution program name of the application software (extension is EXE), that is, the application software is obtained from the CP. The image quality mode table is collated with respect to this application software, and the image quality mode is determined depending on whether or not the application software exists in this table.

Step S2
Based on the determined active application and image quality mode table, the image quality of the graphic controller 21 is adjusted according to the active application. Further, the image quality mode corresponding to the active application is transmitted to the display device 1 via the USB controller 11.

  In this way, when not only the video circuit 7 but also the image quality adjustment values of the graphic controller 21 are associated with each other, image quality adjustment that cannot be adjusted only by the video circuit 7 can be performed by adjusting the graphic controller 21 as well. It has become.

  As an example, assume that the active application is a “word processor”. In that case, since the image quality mode is “Text” from the image quality mode table of FIG. 3, this is transmitted to the display device 1.

  If the image quality mode of the active application is the same as the image quality mode that has already been set, the process ends.

Step S3
In the display device 1, parameters corresponding to the image quality mode are read based on the image quality mode received by the control unit 13 and the parameter table in the memory 9.

  When the active application is “word processor” and the image quality mode is “Text” mode, contrast: 100, brightness: 100, color temperature: 9300K, gamma 1: off, gamma from the parameter table of FIG. 2: OFF, contour correction: OFF is read out.

Step S4
The control unit 13 controls the video circuit 7 according to the read parameters. As a result, an image is displayed on the display device 1 with an image quality corresponding to the active application.

  As described above, since the control unit 13 adjusts the video circuit 7 with the parameters associated with the application software selected by the user, the image quality is automatically set to an appropriate image quality according to the selected application software without being aware of the user. Can be switched to. Therefore, the burden on the user is extremely small, and the image quality switching of the display device 1 can be performed very easily.

  By the way, the nine image quality modes described above are realized only by changing the parameters of the video circuit 7. Therefore, when the image quality adjustment according to the active application is performed, the entire display screen is adjusted uniformly. “Movie 1” or the like is an image quality mode that provides high brightness to optimally display a moving image, but is an image quality mode that is excessively bright and inappropriate for images other than moving images. Therefore, when a moving image is displayed in a window, the computer image becomes too bright and difficult to see.

  Therefore, the active application is related to moving image reproduction, and the gamma value (γ-4 in FIG. 3) for the image quality mode “Window Movie” in the image quality mode table is lowered from the default value. In this case, the video circuit 7 is adjusted according to the parameter set to “Movie 1” or “Movie 2”, and the gamma value of the graphic controller 21 of the computer 3 is adjusted according to the set value γ−4. The As described above, since the graphic controller 21 generally has an “overlay” function, the moving image display region and the display region other than the moving image can be controlled independently, and they can be controlled independently. Image quality can be set. For example, when the gamma value of the graphic controller 21 is set to be the default or optimal for an image other than a moving image, the moving image reproduction area including the intermediate color is displayed slightly darker.

  When, for example, “Movie 1” suitable for moving image reproduction is set as the image quality mode for the application software for moving image reproduction, the moving image display area is optimally displayed, while the other display areas are excessively bright. On the other hand, as described above, when “Window Movie” is set as the image quality mode and the gamma value γ-4 is set lower, the gamma value of the graphic controller 21 is controlled to lower the luminance. At the same time, for example, an image quality mode “Movie 1” corresponding to “Window Movie” is transmitted to the display apparatus 1 side, and the video circuit 7 is adjusted with parameters corresponding thereto.

  As described above, since the gamma value is not reflected in the area where the moving image is reproduced by the “overlay” function, the area where a word processor or the like other than the moving image is displayed becomes dark according to the gamma value. On the other hand, the area where the moving image is reproduced remains as it is. Therefore, even if the gamma value is lowered as described above, only the moving image playback area is displayed brightly, and the image quality suitable for movie viewing remains.

  In addition, in application software such as a moving image or a game, it may be more appropriate to display at low resolution than to display at high resolution. In such a case, it is preferable to set the resolution R-4 of the image quality mode table to a low resolution.

  In addition, this invention is not limited to said embodiment, A deformation | transformation implementation is also possible as follows.

  (1) Although the active application is discriminated by the CPU 15 of the computer 3 in the above embodiment, this discrimination may be performed on the display device 1 side via the USB controller 11.

  This modification corresponds to claims 6 and 18 of the present invention.

  (3) Both the parameter table and the image quality mode table in the embodiment may be provided in the hard disk 19 on the computer 3 side. In this case, parameters corresponding to the active application are read on the computer 3 side, and the parameters themselves are transmitted to the display device 1 to adjust the image quality.

  This modification corresponds to claims 9 and 20 of the present invention.

  (4) A parameter table in which application software and parameters are directly associated may be used without using an image quality mode table in which image quality modes and application software are associated. In that case, a parameter corresponding to the active application is obtained based on this. The parameter table may be provided in the memory 9 on the display device 1 side or the hard disk 19 on the computer 3 side. In the former, active application information is transmitted to the display apparatus 1, and in the latter, parameters are transmitted to the display apparatus 1.

  The former corresponds to claim 5 of the present invention, and the latter corresponds to claims 8 and 20 of the present invention.

  (5) The image quality mode table may include only the association between the application software and the image quality mode, and the image quality adjustment value may not be associated.

  (6) As the image quality adjustment value, it is not necessary to provide both the gamma value and the resolution, and only one of them may be provided.

  (7) As a communication interface, a serial interface may be used without using USB.

It may be. That is, you may employ | adopt the structure which integrated the communication interface.

  (9) In the “Window Movie” mode described above, is the “display state” of the application software, for example, whether the application software is displayed in one of a plurality of windows displayed on the display device 1 ( This is referred to as “window display”), or the display state of whether it is displayed in one maximized window displayed on the entire screen of the display device 1 (referred to as “full screen display”). The image quality mode may be switched according to the determination.

  Specifically, when the moving image is “windowed”, the first image quality in which the image quality adjustment value is set so that both the moving image and the display of the application software displayed in another window are compatible. Mode (for example, “Movie2”) and a second image quality mode (for example, “Movie1”) in which an image quality adjustment value is set so as to be specialized only for the movie when the movie is “full screen display”. Try to switch.

Note that “window display” and “full screen display” may be determined as follows when the OS is Windows, for example.
