　この発明は、画面の輝度を調整する輝度調整装置、輝度調整方法および輝度調整プログラムに関する。 The present invention relates to a brightness adjusting device, a brightness adjusting method, and a brightness adjusting program for adjusting the brightness of a screen.
　従来より、モニタやディスプレイ等を有する装置（例えば、ＰＣ（Personal　Computer）など）において、環境やアプリケーションの使用状況に応じて、画面の輝度を調整する方法が知られている。例えば、ユーザが手動で画面の輝度を調整する操作を行って、画面の輝度の調整を行う方法が知られている。 2. Description of the Related Art Conventionally, there has been known a method of adjusting screen brightness in an apparatus having a monitor, a display, or the like (for example, a PC (Personal Computer) or the like) according to an environment or an application usage state. For example, a method is known in which the user manually adjusts the screen brightness to adjust the screen brightness.
　また、自動で画面の輝度を調整する方法として、使用環境に応じて自動で画面の輝度を調整する方法が存在する（特許文献１～４参照）。例えば、周囲の明るさに関する情報を用いて、自動で画面の輝度を調整する技術が知られている。具体的には、周囲の明るさを検出する周囲光センサが内蔵された装置が、電源投入時において、周囲光センサで周囲の明るさを検知し、検知された周囲の明るさに応じて、画面の輝度を設定する。 Also, as a method for automatically adjusting the screen brightness, there is a method for automatically adjusting the screen brightness according to the use environment (see Patent Documents 1 to 4). For example, a technique for automatically adjusting the brightness of a screen using information on ambient brightness is known. Specifically, a device with a built-in ambient light sensor that detects ambient brightness detects ambient brightness with the ambient light sensor when the power is turned on, and according to the detected ambient brightness, Set the screen brightness.
　また、表示対象となるコンテンツ情報を用いて、自動で画面の輝度を調整する方法が知られている。具体的には、予め設定されたアプリケーションプログラムの起動を検知した場合に、起動したアプリケーションプログラムに応じて、最適な輝度を設定する。 Also, a method of automatically adjusting the screen brightness using content information to be displayed is known. Specifically, when the activation of a preset application program is detected, the optimum luminance is set according to the activated application program.

　図１に示すように、輝度調整装置１０は、キーボード、ポインティングデバイス１２、ディスプレイ１４とバス等を介して接続され、ビデオカード１５、記憶部１６、制御部１７を有する。また、ディスプレイ１４は、光度センサ１３と接続される。以下にこれらの各部の処理を説明する。 As shown in FIG. 1, the brightness adjusting apparatus 10 is connected to a keyboard, a pointing device 12, a display 14 via a bus or the like, and includes a video card 15, a storage unit 16, and a control unit 17. The display 14 is connected to the light intensity sensor 13. The processing of each of these units will be described below.
　キーボード１１およびポインティング１２は、各種情報や各種設定を入力するものである。具体的には、キーボード１１およびポインティング１２は、セキュリティ上目立たせたくないアプリケーションの種類を指定するセキュリティ指定の入力を行う。また、キーボード１１およびポインティング１２は、アプリケーションを起動する旨の指示する入力、画面上のウィンドウの大きさを変更する入力、アクティブウィンドウを指定する入力を行う。 The keyboard 11 and pointing 12 are used to input various information and various settings. Specifically, the keyboard 11 and the pointing 12 perform security designation input that designates the type of application that is not desired to stand out in terms of security. Further, the keyboard 11 and the pointing 12 perform an input for instructing to start an application, an input for changing the size of a window on the screen, and an input for designating an active window.
　また、キーボード１１およびポインティング１２は、セキュリティ指定されたアプリケーションの輝度を変更するか否かを示すフラグである「セキュリティ指定フラグ」の有無を設定する入力、占有率の高いアプリケーションの設定にあわせて画面全体の輝度を変更するか否かを示すフラグである「占有率による全体指定フラグ」の有無を設定する入力、アクティブウィンドウが変更されたら設定にあわせて画面全体の輝度を変更するか否かを示すフラグである「フォーカス変更による変更指定フラグ」の有無を設定する入力を行う。 Further, the keyboard 11 and the pointing 12 are displayed in accordance with an input for setting the presence / absence of a “security designation flag” that is a flag indicating whether or not to change the luminance of the security designated application, and the setting of the application with a high occupation ratio. Input to set the presence / absence of “overall specification flag by occupancy rate” which is a flag indicating whether or not to change the overall brightness, if the active window is changed, whether to change the brightness of the entire screen according to the setting An input for setting the presence / absence of a “change designation flag by changing focus” is performed.
　光度センサ１３は、輝度調整装置１０の使用場所の外光の明るさを解析する。具体的には、光度センサ１３は、所定の間隔で外光の明るさを解析し、解析された外光の明るさのレベルをディスプレイ１４に通知する。 The light intensity sensor 13 analyzes the brightness of outside light at the place where the brightness adjusting device 10 is used. Specifically, the light intensity sensor 13 analyzes the brightness of outside light at a predetermined interval, and notifies the display 14 of the analyzed brightness level of outside light.
　光度センサ１３の位置の例について図２を用いて説明する。図２に例示するように、光度センサ１３は、外光をチェックしやすいように、ディスプレイ１４の上部に配置されている。また、光度センサ１３は、ディスプレイ１４の近傍に配置されることにより、ディスプレイ１４に入り込む光量も考慮した外光の明るさをチェックすることが可能となっている。つまり、その場の環境の明るさだけでなく、ユーザが光源（室外での太陽光や室内での蛍光灯）に対してディスプレイ１４をどちらに向けているかで変化する外光の強弱も解析する。 An example of the position of the light intensity sensor 13 will be described with reference to FIG. As illustrated in FIG. 2, the light intensity sensor 13 is arranged on the upper part of the display 14 so that the outside light can be easily checked. Further, the light intensity sensor 13 is arranged in the vicinity of the display 14 so that it is possible to check the brightness of external light in consideration of the amount of light entering the display 14. In other words, not only the brightness of the environment at the spot, but also the intensity of the external light that changes depending on which direction the display 14 is directed to the light source (sunlight outdoors or fluorescent lamps indoors) is analyzed. .
　ディスプレイ１４は、輝度調整装置１０から輝度設定情報を受信し、受信された輝度設定情報に基づいて画面全体の輝度または画面の一部の輝度を変更しつつ、起動されたアプリケーションに対応するアプリケーションウィンドウなどを表示する。 The display 14 receives the luminance setting information from the luminance adjusting device 10 and changes the luminance of the entire screen or the luminance of a part of the screen based on the received luminance setting information, and an application window corresponding to the activated application. Etc. are displayed.
　ディスプレイ１４は、外光の明るさと輝度レベルとが対応付けられた輝度テーブルを用いて輝度レベルを決定する輝度テーブル値判定部１４ａを有する。ここで、輝度テーブルについて図３を用いて具体的に説明する。図３に示すように、輝度テーブルは、外光の明るさレベル（図３では、「外光」と記載）と輝度レベルとを対応付けて記憶する。 The display 14 includes a luminance table value determination unit 14a that determines a luminance level using a luminance table in which the brightness of external light and the luminance level are associated with each other. Here, the luminance table will be specifically described with reference to FIG. As shown in FIG. 3, the brightness table stores the brightness level of external light (indicated as “external light” in FIG. 3) and the brightness level in association with each other.
　輝度テーブル値判定部１４ａは、光度センサ１３から外光の明るさレベルを受信し、受信された明るさレベルに対応する輝度レベルを輝度テーブルから読み出す。そして、輝度テーブル値判定部１４ａは、読み出された輝度レベルを輝度調整装置１０に通知する。 The brightness table value determination unit 14a receives the brightness level of external light from the light intensity sensor 13, and reads the brightness level corresponding to the received brightness level from the brightness table. Then, the luminance table value determination unit 14a notifies the luminance adjustment device 10 of the read luminance level.
　ビデオカード１５は、輝度調整装置１０で処理された情報をディスプレイ１５で表示するように制御する。 The video card 15 controls the display 15 to display information processed by the brightness adjusting device 10.
　記憶部１６は、制御部１７による各種処理に必要なデータおよびプログラムを格納し、制御部１７によってデータおよびプログラムが読み出されるが、特に、制御プログラム１６ａおよび各種アプリケーション１６ｂを有する。この制御プログラム１６ａは、各種アプリケーション１６ｂの実行を制御するためのプログラムである。また、各種アプリケーション１６ｂは、動画のアプリーション、文書作成などの一般アプリケーション、ウィルスチェックのアプリケーションおよび音楽再生のアプリケーションなどがある。 The storage unit 16 stores data and programs necessary for various types of processing by the control unit 17, and the data and programs are read by the control unit 17. In particular, the storage unit 16 includes a control program 16a and various applications 16b. The control program 16a is a program for controlling the execution of various applications 16b. The various applications 16b include a moving image application, a general application such as document creation, a virus check application, and a music playback application.
　制御部１７は、各種の処理手順などを規定したプログラムおよび所要データを格納するための内部メモリを有し、これらによって種々の処理を実行するが、特に、セキュリティ指定受付部１７ａ、外光情報取得部１７ｂ、アプリケーション解析部１７ｃ、輝度設定部１７ｄを有する。 The control unit 17 has an internal memory for storing a program that defines various processing procedures and necessary data, and executes various processes using these programs. In particular, the security designation receiving unit 17a, external light information acquisition, and the like are executed. A unit 17b, an application analysis unit 17c, and a luminance setting unit 17d.
　また、制御部１７は、図４に示すように、アプリケーションの輝度テーブルを内部メモリに格納する。図４を用いて具体的に説明すると、輝度テーブルは、アプリケーションの種類を示す「アプリの種類」、ディスプレイ１４から通知された「輝度レベル」、ディスプレイの輝度を設定するための情報である「輝度設定値」がそれぞれ対応付けて記憶されている。輝度調整装置１０の制御部１７では、輝度設定値の値が大きいほど、ディスプレイに表示される画像を明るくするように設定し、輝度設定値が小さいほどディスプレイに表示される画像が暗くなるように設定する。 Further, as shown in FIG. 4, the control unit 17 stores the luminance table of the application in the internal memory. More specifically, the luminance table is an “application type” indicating the type of application, a “brightness level” notified from the display 14, and “brightness” which is information for setting the luminance of the display. “Set values” are stored in association with each other. In the control unit 17 of the brightness adjusting device 10, the larger the brightness setting value, the brighter the image displayed on the display, and the smaller the brightness setting value, the darker the image displayed on the display. Set.
　つまり、輝度調整装置１０は、動画やテレビのウィンドウについて、文書作成などの一般アプリケーションウィンドウと比較して、より明るく表示するように設定する。また、輝度テーブルでは、動画のウィンドウを表示している状況であっても、外光が暗い場合には、ユーザの視覚的負担とならないように、輝度設定値を落とすようにしている。 That is, the brightness adjusting device 10 is set so that a moving image or a television window is displayed brighter than a general application window for document creation or the like. In the luminance table, even when a moving image window is displayed, the luminance setting value is lowered so as not to be a visual burden on the user when the outside light is dark.
　また、輝度調整装置１０は、セキュリティ上目立たせたくないウィンドウについて、暗く表示するように設定し、ウィルスチェックや音楽再生ソフトなどの画面を見る必要のないアプリケーションについては、外光の明暗に関係なく、輝度設定値を最低としている。なお、輝度テーブルの各パラメータ（アプリの種類、輝度レベル、輝度設定値）については、ユーザの好みに応じて、カスタマイズすることが可能である。 In addition, the brightness adjusting device 10 is set so that a window that is not conspicuous for security is displayed darkly, and an application that does not need to view a screen such as a virus check or music playback software is irrespective of the brightness of external light. The brightness setting value is the lowest. It should be noted that each parameter of the brightness table (application type, brightness level, brightness setting value) can be customized according to user preferences.
　また、制御部１７は、ユーザによって有無が設定されるフラグを内部メモリに格納する。具体的には、図５に示すように、セキュリティ指定されたアプリケーションの輝度を変更するか否かを示すフラグである「セキュリティ指定フラグ」、占有率の高いアプリケーションの設定にあわせて画面全体の輝度を変更するか否かを示すフラグである「占有率による全体指定フラグ」、アクティブウィンドウが変更されたら設定にあわせて画面全体の輝度を変更するか否かを示すフラグである「フォーカス変更による変更指定フラグ」を格納する。 In addition, the control unit 17 stores in the internal memory a flag that is set by the user. Specifically, as shown in FIG. 5, a “security designation flag” that is a flag indicating whether or not to change the luminance of the security-designated application, and the luminance of the entire screen in accordance with the setting of the application with a high occupation ratio "Whole Specified Flag by Occupancy Rate" which is a flag indicating whether or not to change, and a flag indicating whether to change the brightness of the entire screen according to the setting when the active window is changed "Change by changing focus" Stores "designated flag".
　セキュリティ指定受付部１７ａは、所定のアプリケーションの種類について、輝度が低く表示されるように設定するセキュリティ設定を受け付ける。具体的には、セキュリティ指定受付部１７ａは、キーボード１１およびポインティング１２からセキュリティ上目立たせなくないアプリケーションの種類を指定するセキュリティ指定を受け付けて、内部メモリにセキュリティ指定のアプリケーションの種類を格納する。 The security designation receiving unit 17a receives a security setting for setting a predetermined application type so that the brightness is displayed low. Specifically, the security designation receiving unit 17a receives a security designation that designates an application type that does not stand out in terms of security from the keyboard 11 and the pointing 12, and stores the security designated application type in the internal memory.
　外光情報取得部１７ｂは、外光の明るさに関する外光情報を取得する。具体的には、外光情報取得部１７ｂは、ディスプレイ１４から通知された輝度レベルが前回通知された輝度レベルと比較して変化したか監視し、輝度レベルが変化した場合には、起動中のアプリケーションの種類を解析する旨の指示をアプリケーション解析部１７ｃに通知する。 The external light information acquisition unit 17b acquires external light information related to the brightness of external light. Specifically, the external light information acquisition unit 17b monitors whether or not the luminance level notified from the display 14 has changed compared to the previously notified luminance level. An instruction to analyze the application type is sent to the application analysis unit 17c.
　アプリケーション解析部１７ｃは、起動中のアプリケーションの種類を解析する。また、アプリケーション解析部１７ｃは、起動中のアプリケーションが複数ある場合には、起動中の各アプリケーションの画面の占有率を解析し、また、起動中の各アプリケーションのウィンドウのうちアクティブウィンドウに指定されたウィンドウを特定する。 The application analysis unit 17c analyzes the type of application being started. In addition, when there are a plurality of running applications, the application analysis unit 17c analyzes the occupation ratio of the screen of each running application, and is designated as the active window among the windows of each running application. Identify the window.
　具体的には、アプリケーション解析部１７ｃは、外光情報取得部１７ｂから起動中のアプリケーションの種類を解析する旨の指示を受信すると、起動中のアプリケーションの種類を解析する。そして、アプリケーション解析部１７ｃは、複数のアプリケーションが起動中であるか判定する。 Specifically, when receiving an instruction to analyze the type of the active application from the external light information acquisition unit 17b, the application analysis unit 17c analyzes the type of the active application. Then, the application analysis unit 17c determines whether a plurality of applications are being activated.
　その結果、アプリケーション解析部１７ｃは、複数のアプリケーションが起動していないと判定した場合には、起動中のアプリケーションの種類および外光の明るさに応じて輝度を設定する処理を行う旨の指示を輝度設定部１７ｂに通知する。 As a result, when the application analysis unit 17c determines that a plurality of applications are not activated, the application analysis unit 17c issues an instruction to perform a process of setting the luminance according to the type of the activated application and the brightness of external light. Notify the brightness setting unit 17b.
　また、アプリケーション解析部１７ｃは、複数のアプリケーションが起動していると判定した場合には、複数のアプリケーションのうち、いずれのアプリケーションを輝度調整に用いるかを決定する処理を行う。 In addition, when it is determined that a plurality of applications are activated, the application analysis unit 17c performs a process of determining which of the plurality of applications is used for brightness adjustment.
　アプリケーション解析部１７ｃは、アプリケーションを輝度レベル設定に用いるかを決定する処理として、占有率による全体指定フラグが有るか判定し、占有率による全体指定フラグが有る場合には、占有率の高いアプリケーションの設定に合わせて画面全体の輝度を変更する旨の指示を輝度設定部１７ｄに通知する。 The application analysis unit 17c determines whether or not there is an overall designation flag based on the occupation rate as a process for determining whether to use the application for setting the luminance level. If there is an overall designation flag based on the occupation rate, the application analysis unit 17c An instruction to change the luminance of the entire screen in accordance with the setting is notified to the luminance setting unit 17d.
　また、アプリケーション解析部１７ｃは、アプリケーションを輝度レベル設定に用いるかを決定する処理として、フォーカス変更による変更指定フラグが有るか判定し、フォーカス変更による変更指定フラグが有る場合には、アクティブウィンドウに指定されたアプリケーションの設定に合わせて画面全体の輝度を変更する旨の指示を輝度設定部１７ｄに通知する。 In addition, the application analysis unit 17c determines whether or not there is a change designation flag due to focus change as processing for determining whether to use the application for luminance level setting. If there is a change designation flag due to focus change, the application analysis unit 17c is designated as an active window. The brightness setting unit 17d is notified of an instruction to change the brightness of the entire screen in accordance with the set application.
　輝度設定部１７ｄは、外光情報およびアプリケーションの種類に応じて、輝度の設定を変更する。具体的には、輝度設定部１７ｄは、アプリケーション解析部１７ｃから起動中のアプリケーションの種類および外光の明るさに応じて輝度を設定する処理を行う旨の指示を受け付けた場合には、起動中のアプリケーションに決定し、また、占有率の高いアプリケーションの設定に合わせて画面全体の輝度を変更する旨の指示を受け付けた場合には、占有率の高いアプリケーションに決定し、また、アクティブウィンドウに指定されたアプリケーションの設定に合わせて画面全体の輝度を変更する旨の指示を受け付けた場合には、アクティブウィンドウに指定されたアプリケーションを輝度調整に用いるアプリケーションに決定する。 The luminance setting unit 17d changes the luminance setting according to the external light information and the type of application. Specifically, when the luminance setting unit 17d receives an instruction from the application analysis unit 17c to set the luminance according to the type of application being activated and the brightness of external light, the luminance setting unit 17d is being activated. If an instruction is received to change the brightness of the entire screen according to the settings of an application with a high occupancy ratio, the application is determined to have a high occupancy ratio and is designated as the active window. When an instruction to change the brightness of the entire screen is received in accordance with the set application, the application specified for the active window is determined as the application used for brightness adjustment.
　そして、輝度設定部１７ｄは、セキュリティ指定フラグが有るか判定し、セキュリティ指定フラグがある場合には、輝度調整に用いられるアプリケーションの種別がセキュリティ設定されているか判定する。 The brightness setting unit 17d determines whether there is a security designation flag. If there is a security designation flag, the brightness setting unit 17d determines whether the application type used for brightness adjustment is security set.
　その結果、輝度設定部１７ｄは、輝度調整に用いられるアプリケーションの種別がセキュリティ設定されている場合には、そのアプリケーションがセキュリティ上目立たせたくないアプリケーションであると判定し、アプリケーションの輝度テーブルからアプリの種類が「セキュリティ上目立たせたくないウィンドウ」であって、ディスプレイから取得された輝度レベル（Ａ～Ｃのいずれか）に対応する輝度設定値（１～３のいずれか）を読み出す。 As a result, when the security type is set for the application type used for the brightness adjustment, the brightness setting unit 17d determines that the application is an application that should not be conspicuous in terms of security, and determines the application from the brightness table of the application. The brightness setting value (any one of 1 to 3) corresponding to the brightness level (any one of A to C) acquired from the display is read out, with the type being “a window that does not want to stand out for security”.
　また、輝度設定部１７ｄは、セキュリティ指定フラグがない場合、または輝度調整に用いられるアプリケーションの種別がセキュリティ設定されていない場合には、解析されたアプリケーションの種類に対応する輝度設定値を輝度テーブルから読み出す。 In addition, when there is no security designation flag or when the type of application used for luminance adjustment is not security-set, the luminance setting unit 17d determines the luminance setting value corresponding to the analyzed application type from the luminance table. read out.
　そして、輝度設定部１７ｄは、ウィンドウ単位で個別の輝度調整を行う旨の設定がなされているか判定する。その結果、輝度設定部１７ｄは、ウィンドウ単位で個別の輝度調整を行う旨の設定がなされていない場合には、画面全体の輝度の設定を変更する。また、輝度設定部１７ｄは、ウィンドウ単位で個別の輝度調整を行う旨の設定がなされている場合には、ウィンドウ単位での輝度の設定を変更する。 Then, the luminance setting unit 17d determines whether or not a setting for performing individual luminance adjustment for each window is made. As a result, the luminance setting unit 17d changes the setting of the luminance of the entire screen when the setting for performing individual luminance adjustment for each window is not made. Also, the luminance setting unit 17d changes the setting of the luminance in the window unit when the setting for performing the individual luminance adjustment in the window unit is made.
　ここで、輝度設定処理の一例について、図６を用いて説明する。図６に示すように、輝度調整装置１０は、使用環境の外光の明るさをチェックし、実行中のアプリケーションの種類を解析し、外光の明るさおよびアプリケーションの種類に応じて、輝度設定処理を行っている。 Here, an example of the brightness setting process will be described with reference to FIG. As shown in FIG. 6, the brightness adjusting apparatus 10 checks the brightness of the external light in the usage environment, analyzes the type of application being executed, and sets the brightness according to the brightness of the external light and the type of application. Processing is in progress.
　そして、図６の例では、輝度調整装置１０は、複数のアプリケーションウィンドウが表示されており、左のアプリケーションウィンドウでは動画を表示されており、右のアプリケーションウィンドウではメール文章（この図の例では、メールに関するアプリケーションがセキュリティ指定されていることとする）が表示されている。 In the example of FIG. 6, the brightness adjusting device 10 displays a plurality of application windows, the left application window displays a moving image, and the right application window displays mail text (in this example, The application related to e-mail is designated as security).
　図６に示すように、輝度調整装置１０は、右のアプリケーションウィンドウについて、動画ウィンドウであって占有率が高いので、明るく表示されるように、輝度が設定されている。また、輝度調整装置１０は、左のアプリケーションウィンドウについて、セキュリティ指定されたアプリーケーションとして輝度が低く設定されている。また、輝度調整装置１０は、フォーカスによりアクティブウィンドウが変更すると、変更されたアクティブウィンドウのアプリケーションの種類に応じて、輝度の設定を変更する。 As shown in FIG. 6, the brightness adjustment apparatus 10 is set to be brightly displayed because the right application window is a moving image window and has a high occupation rate. In addition, the brightness adjusting device 10 is set to have a low brightness as the security-designated application for the left application window. In addition, when the active window is changed by the focus, the brightness adjusting apparatus 10 changes the brightness setting according to the application type of the changed active window.

　図７に示すように、光度センサ１３は、所定の間隔で外光の明るさを解析し、解析された外光の明るさのレベルの変更をディスプレイ１４に通知する（ステップＳ１０１）。そして、ディスプレイ１４は、光度センサ１３から外光の明るさレベルを取得し（ステップＳ１０２）、保持する輝度テーブル（図３参照）で輝度レベルに変換して（ステップＳ１０３）、輝度調整装置１０に輝度レベルを通知する（ステップＳ１０４）。 As shown in FIG. 7, the light intensity sensor 13 analyzes the brightness of the outside light at a predetermined interval, and notifies the display 14 of the change in the analyzed brightness level of the outside light (step S101). Then, the display 14 acquires the brightness level of external light from the light intensity sensor 13 (step S102), converts the brightness level into a brightness level using the held brightness table (see FIG. 3) (step S103), and sends it to the brightness adjusting apparatus 10. The brightness level is notified (step S104).
　次に、図８を用いて輝度調整装置１０の全体の処理手順を説明する。図８に示すように、輝度調整装置１０は、ディスプレイ１４から通知された輝度レベルが前回通知された輝度レベルと比較して変化したか監視し（ステップＳ２０１）、輝度レベルが変化した場合には（ステップＳ２０１肯定）、起動中のアプリケーションの種類を解析する（ステップＳ２０２）。 Next, the overall processing procedure of the brightness adjusting apparatus 10 will be described with reference to FIG.
