Description

電子装置、制御方法及びプログラムElectronic device, control method and program
　本発明は、マルチウィンドウシステムにおいて動画表示を行う技術に関する。 The present invention relates to a technique for displaying a moving image in a multi-window system.
　従来、表示画面上に複数のウィンドウを同時に表示できるようにしたソフトウェアシステム、即ちマルチウィンドウシステムを採用した電子装置（コンピュータ等）が広く利用されている。 2. Description of the Related Art Conventionally, software systems that enable a plurality of windows to be displayed simultaneously on a display screen, that is, electronic devices (computers or the like) that employ a multi-window system have been widely used.
　このマルチウィンドウシステムが動作する電子装置であれば、複数のプログラムを同時に実行し、それらプログラムによる表示を夫々のウィンドウに表示できる。例えば、テレビ番組等の動画を視聴しつつ、動画再生以外の機能（文書作成やメールチェック等）を主として使用することができる。 An electronic device that can operate this multi-window system can execute a plurality of programs at the same time and display the display of each program in each window. For example, while watching a moving image such as a TV program, functions other than moving image reproduction (document creation, mail check, etc.) can be mainly used.
　このため、ユーザは、マウスなどのポインティングデバイスで、これらのウィンドウを選択的に切り替えることによって、利用するアプリケーションを選択する。 For this reason, the user selects an application to be used by selectively switching these windows with a pointing device such as a mouse.
　このとき、ユーザが選択したウィンドウ（アクティブウィンドウ）が最前面に表示されて処理対象になり、このウィンドウと重なっている他のウィンドウは、その背面に隠れることになる。 At this time, the window (active window) selected by the user is displayed in the foreground and becomes a processing target, and other windows overlapping with this window are hidden behind the window.
　しかし、動画を表示するウィンドウが隠れてしまったのでは視聴できなくなるため、動画を視聴しつつ他のウィンドウを選択する場合には、動画を表示するウィンドウを画面端へ移動し、隠れない程度にウィンドウサイズを小さくするようにユーザが操作していた。 However, if the window that displays the movie is hidden, you cannot view it. If you select another window while watching the movie, move the window that displays the movie to the edge of the screen so that it is not hidden. The user was operating to reduce the window size.

The information input from the above and the information read from the storage unit 17 are processed. In particular, in the present embodiment, the CPU 11 functions as the moving image reproduction unit 21 by executing the moving image reproduction program, and functions as the window state detection unit 14 and the display control unit 16 by executing the display control program.
　図４は、アクティブウィンドウを切り替えた際、本実施形態のコンピュータ１０がプログラムに従って実行する制御方法の説明図である。 FIG. 4 is an explanatory diagram of a control method executed by the computer 10 according to the present embodiment according to a program when the active window is switched.
　ユーザが、キーボードやマウスで動画の再生を選択する、或はリモコン１３Ｂのテレビボタン３１，ＤＶＤボタン３２，ネットＴＶボタン３３を選択すると、動画再生プログラム（テレビジョン再生アプリケーション２８Ａ、ＤＶＤ動画再生アプリケーション２８Ｂ、ネットワーク配信動画再生アプリケーション２８Ｃ）が起動し、該動画再生プログラムに従って動画再生部２１が生成した映像信号を表示制御部１６を介して動画表示ウィンドウに表示させる（ステップ１、以下Ｓ１のように略記する）。本実施形態においてウィンドウ状態検出部１４は、この動画再生部２１による映像信号を表示するウィンドウを動画表示ウィンドウとして判別する。また、これに限らずウィンドウ状態検出部１４は、所定の動画データの再生が選択された場合、例えば".mpg"や".avi"等の拡張子が付いたファイル、ストリーミングデータの再生が選択された場合に、このデータを表示しているウィンドウを動画表示ウィンドウと判別しても良い。 When the user selects playback of a moving image with the keyboard or mouse, or selects the TV button 31, the DVD button 32, or the net TV button 33 of the remote controller 13B, a moving image playback program (television playback application 28A, DVD video playback application 28B). , The network distribution video playback application 28C) is started, and the video signal generated by the video playback unit 21 in accordance with the video playback program is displayed on the video display window via the display control unit 16 (step 1, hereinafter abbreviated as S1). To do). In the present embodiment, the window state detection unit 14 determines a window for displaying a video signal by the moving image reproduction unit 21 as a moving image display window. Not limited to this, the window state detection unit 14 selects, for example, a file with an extension such as “.mpg” or “.avi”, or reproduction of streaming data when reproduction of predetermined moving image data is selected. In such a case, the window displaying this data may be determined as the moving image display window.
　そして、ウィンドウ状態検出部１４は、所定期間毎（本例では１００ｍｓ毎）に動画表示ウィンドウの状態の切り替わりが無いか、即ちポーリングにより動画表示ウィンドウのアクティブへの切り替わり或は非アクティブへの切り替わりを検出する（Ｓ２）。 Then, the window state detection unit 14 determines whether there is no switching of the state of the moving image display window every predetermined period (in this example, every 100 ms), that is, the switching of the moving image display window to active or inactive by polling. Detect (S2).
　この動画表示ウィンドウの切り替わりが無ければ待機し、動画表示ウィンドウの切り替わりが有った場合、ウィンドウ状態検出部１４は、動画表示ウィンドウがアクティブであるか否かを判定する（Ｓ３）。 If there is no switching of the moving image display window, the process waits. If there is a switching of the moving image display window, the window state detection unit 14 determines whether the moving image display window is active (S3).
　ここで、動画表示ウィンドウが非アクティブに切り替わったと判定した場合、ウィンドウ状態検出部１４は、更に、この切り替わりが、初めてであるか否かを判定する（Ｓ４）。例えば、この切り替わりが、動画表示プログラムのインストール後初めて或は動画表示プログラムの起動から終了までの間で初めてであるか否かを判定する。 Here, when it is determined that the moving image display window is switched to inactive, the window state detection unit 14 further determines whether or not this switching is the first time (S4). For example, it is determined whether or not this switching is the first time after the installation of the moving image display program or the first time from the start to the end of the moving image display program.
　もし、初めて動画表示ウィンドウが非アクティブに切り替わったのであれば、表示制御部１６は、現在の動画表示ウィンドウのサイズを第１ウィンドウサイズとして記憶部１７に記憶させ（Ｓ５）、該動画表示ウィンドウを所定の第２ウィンドウサイズに変更する（Ｓ６）。ここで所定の第２ウィンドウサイズとは、予めデフォルト値を設定しておいても良いし、ユーザが操作入力部１３で所望のサイズを入力し、記憶部１７に記憶させて（設定して）おくものでも良い。 If the moving image display window is switched to inactive for the first time, the display control unit 16 stores the current moving image display window size in the storage unit 17 as the first window size (S5). The window size is changed to a predetermined second window size (S6). Here, the predetermined second window size may be set in advance as a default value, or the user inputs a desired size with the operation input unit 13 and stores (sets) it in the storage unit 17. You can leave it.
　なお、表示制御部１６は、動画表示ウィンドウを第２ウィンドウサイズに変更する際、ウィンドウのサイズだけを変更するのではなく、動画を縦横比を変えずにウィンドウサイズに合わせて縮小表示する。 In addition, when changing the moving image display window to the second window size, the display control unit 16 does not change only the size of the window, but reduces the moving image to the window size without changing the aspect ratio.
　また、ステップ４で動画表示ウィンドウの非アクティブへの切り替わりが初めてでない、即ち第１ウィンドウサイズが設定済み（記録済み）の場合、表示制御部１６は、第１ウィンドウサイズの記録を省略して動画表示ウィンドウを所定の第２ウィンドウサイズに変更する（Ｓ６）。 In addition, when the moving image display window is not switched to inactive for the first time in step 4, that is, when the first window size is already set (recorded), the display control unit 16 omits the recording of the first window size and displays the moving image. The display window is changed to a predetermined second window size (S6).
　一方、ステップ３で、動画表示ウィンドウがアクティブに切り替わったと判定された場合、表示制御部１６は、記憶部１７を参照し、動画表示ウィンドウを第１ウィンドウサイズに変更する（Ｓ７）。 On the other hand, when it is determined in step 3 that the moving image display window has been switched to active, the display control unit 16 refers to the storage unit 17 and changes the moving image display window to the first window size (S7).
　図５，図６は、上記制御方法によって切り替わるウィンドウの状態を説明した図である。 5 and 6 are diagrams for explaining the state of the window that is switched by the above control method.
　図５，図６において、４１が動画表示ウィンドウ、４２が他のウィンドウであり、それぞれ上部のタイトルバー４１Ａ，４２Ａがハイライト時（図では斜線を記した時）にアクティブとなっている。 5 and 6, reference numeral 41 denotes a moving image display window, 42 denotes another window, and the upper title bars 41A and 42A are active when highlighted (indicated by hatched lines in the figure).
　ユーザが動画を視聴したい場合、動画表示ウィンドウ４１を選択してアクティブにし、図５に示すように最前面に表示させる。このときのサイズＷ１×Ｈ１が第１ウィンドウサイズである。 When the user wants to watch a moving image, the moving image display window 41 is selected and activated, and is displayed in the foreground as shown in FIG. The size W1 × H1 at this time is the first window size.
　そして、ユーザが、動画を見ながら他の作業をしたい場合、他のウィンドウ４２を選択してアクティブウィンドウを切り替え、図６に示すように該他のウィンドウ４２を最前面に表示させる。 When the user wants to perform other work while watching the moving image, the user selects another window 42 to switch the active window, and displays the other window 42 in the foreground as shown in FIG.
　このとき動画表示ウィンドウ４１が非アクティブに切り替わったことをウィンドウ状態検出部１４が検出し、表示制御部１６が動画表示ウィンドウ４１を第２ウィンドウサイズ（Ｗ２×Ｈ２）に切り替える。 At this time, the window state detection unit 14 detects that the moving image display window 41 is switched to inactive, and the display control unit 16 switches the moving image display window 41 to the second window size (W2 × H2).
　このように、本実施形態によれば、ユーザが選択入力部１３でウィンドウを選択する等の操作を行った場合に、電子装置１０がアクティブウィンドウの切り替わりを検出して動画表示ウィンドウのサイズを自動的に変更する。従って、文書作成やメールチェック等の主たる作業を行いながら動画を視聴する場合に、動画表示ウィンドウが隠れないように小さくしたり、小さくした動画表示ウィンドウを標準サイズに戻したりするユーザの手間を軽減できる。 Thus, according to the present embodiment, when the user performs an operation such as selecting a window with the selection input unit 13, the electronic device 10 detects the switching of the active window and automatically sets the size of the moving image display window. Change. Therefore, when watching a movie while performing the main work such as document creation and e-mail check, the movie display window is reduced so as not to be hidden, and the user's trouble of returning the reduced movie display window to the standard size is reduced. it can.
　〈変形例〉
　上記実施形態において、第１ウィンドウサイズと第２ウィンドウサイズは、第１ウィンドウサイズよりも第２ウィンドウサイズが小さければ、任意のサイズに設定して良い。 <Modification>
In the above embodiment, the first window size and the second window size may be set to arbitrary sizes as long as the second window size is smaller than the first window size.
　また、図４の例では、動画表示ウィンドウの非アクティブへの切り替わりが初めてであった場合に第１ウィンドウサイズを記録したが、これに限らずステップ４を省略して図７に示すように、動画表示ウィンドウが非アクティブに変る度に第１ウィンドウサイズを記録するようにしても良い。 In the example of FIG. 4, the first window size is recorded when the moving image display window is switched to inactive for the first time. However, the present invention is not limited to this, and step 4 is omitted, as shown in FIG. The first window size may be recorded each time the moving image display window changes to inactive.
　更に、図７のステップ５を省略して切り替え時に第１ウィンドウサイズの記録を行うのではなく、予め設定したサイズに変更する構成としても良い。 Furthermore, the configuration may be such that step 5 in FIG. 7 is omitted and the first window size is not recorded at the time of switching, but is changed to a preset size.
　該第１ウィンドウサイズを予め設定する場合、例えば、ユーザが操作入力部１３Ａで動画表示ウィンドウを所望のサイズに調整した状態で設定メニューを開き、第１ウィンドウサイズの設定（不図示）を選択する。これに応じ、電子装置１０は、第１ウィンドウサイズの設定が選択されたときの動画表示ウィンドウのサイズを第１ウィンドウサイズとして記憶部１７に記憶する。 When the first window size is set in advance, for example, the user opens the setting menu with the moving image display window adjusted to a desired size by the operation input unit 13A, and selects the first window size setting (not shown). . In response to this, the electronic apparatus 10 stores the size of the moving image display window when the setting of the first window size is selected in the storage unit 17 as the first window size.
　また、第２ウィンドウサイズについても同様に設定できる。例えば、ユーザが、図８に示す動画表示ウィンドウ４３の左下隅４３Ｂをマウスで右上へドラッグして所望サイズの動画表示ウィンドウ４４に縮め、選択メニュー４４Ｃを開いて第２ウィンドウサイズの設定４４Ｄを選択する。これに応じ、電子装置１０は、第２ウィンドウサイズの設定４４Ｄが選択されたときの動画表示ウィンドウのサイズを第２ウィンドウサイズとして記憶部１７に記憶する。 Also, the second window size can be set in the same way. For example, the user drags the lower left corner 43B of the moving image display window 43 shown in FIG. 8 to the upper right by dragging the mouse to the moving image display window 44 having a desired size, opens the selection menu 44C, and selects the second window size setting 44D. To do. In response to this, the electronic apparatus 10 stores the size of the moving image display window when the second window size setting 44D is selected in the storage unit 17 as the second window size.
　図９は、アクティブウィンドウの切り替えに応じて、動画表示ウィンドウを予め設定した第１ウィンドウサイズ或は第２ウィンドウサイズに変更する制御方法の説明図である。 FIG. 9 is an explanatory diagram of a control method for changing the moving image display window to the preset first window size or second window size in accordance with switching of the active window.
　上述のとおり動画表示ウィンドウがアクティブに切り替わったか否かを判定し（Ｓ１～３）、アクティブに切り替わった場合には動画表示ウィンドウを第２ウィンドウサイズから第１ウィンドウサイズに変更し（Ｓ９）、非アクティブに切り替わった場合には動画表示ウィンドウを第１ウィンドウサイズから第２ウィンドウサイズに変更する（Ｓ８）。 As described above, it is determined whether or not the moving image display window has been switched to active (S1 to 3). If the moving image display window has been switched to active, the moving image display window is changed from the second window size to the first window size (S9). If it is switched to active, the moving image display window is changed from the first window size to the second window size (S8).
　なお、第２ウィンドウサイズは、図８で説明した絶対的な値に限らず、動画表示ウィンドウのアクティブ時のサイズ（第１ウィンドウ）に対して所定の割合で下げた（小さくした）サイズとなるように相対的な値を設定しても良い。 Note that the second window size is not limited to the absolute value described with reference to FIG. 8, but is a size that is reduced (reduced) by a predetermined ratio with respect to the active size (first window) of the moving image display window. A relative value may be set as described above.
　例えば、第２ウィンドウサイズを１／２や１／３と設定した場合、動画表示ウィンドウが非アクティブに切り替わった際に、第１ウィンドウサイズの動画表示ウィンドウを１／２或は１／３に変更する。 For example, if the second window size is set to 1/2 or 1/3, the moving image display window of the first window size is changed to 1/2 or 1/3 when the moving image display window is switched to inactive. To do.
　同様に、図４の処理方法において、第２ウィンドウサイズを第１ウィンドウサイズに対する割合で設定し、ステップ５のように、動画表示ウィンドウが非アクティブに切り替わった際、現在のウィンドウサイズ（アクティブ時のサイズ）を第１ウィンドウサイズとして記憶する場合、ステップ６では動画表示ウィンドウをアクティブ時のサイズから所定割合で下げた（小さくした）サイズとする。 Similarly, in the processing method of FIG. 4, when the second window size is set as a ratio to the first window size and the moving image display window is switched to inactive as in step 5, the current window size (when active is displayed). In the case where the (size) is stored as the first window size, in step 6, the moving image display window is set to a size that is reduced (reduced) by a predetermined ratio from the active size.
　また、図５に示すように、第１ウィンドウサイズの動画表示ウィンドウ４１が、動画を表示する動画表示欄４１Ｂと、動画に係るタイトルや概説等の情報を表示する情報表示欄４１Ｃとを有している場合、第２ウィンドウサイズに変更する際にこの情報表示欄４１Ｃを省略（非表示）しても良い。 Further, as shown in FIG. 5, the moving image display window 41 of the first window size has a moving image display column 41B for displaying moving images and an information display column 41C for displaying information such as titles and outlines related to moving images. In this case, the information display column 41C may be omitted (not displayed) when changing to the second window size.
　また、動画表示ウィンドウを小サイズに変更する場合、ウィンドウの隅や中央など所定の位置を基準に縮小する構成としても良い。例えば図６では、右上隅を基準位置としてウィンドウを縮小している。この基準位置は、予め設定して記憶部１７に記憶させておく。例えば図８に示したように、左下隅をドラッグして右上隅を基準位置（移動しない点）として小サイズのウィンドウを設定した場合、ウィンドウサイズと共に基準位置（図では右上隅）も記憶する。 In addition, when the moving image display window is changed to a small size, the moving image display window may be reduced based on a predetermined position such as a corner or center of the window. For example, in FIG. 6, the window is reduced with the upper right corner as the reference position. This reference position is set in advance and stored in the storage unit 17. For example, as shown in FIG. 8, when the lower left corner is dragged and a small window is set with the upper right corner as the reference position (a point that does not move), the reference position (upper right corner in the figure) is also stored together with the window size.
　更に、動画表示ウィンドウを小サイズに変更する場合、決まったサイズに限らず、アクティブなウィンドウと重ならないサイズに変更する構成でもよい。例えば、図１０に示すように動画表示ウィンドウ４１が非アクティブ、他のウィンドウ４２がアクティブに切り替わり、動画表示ウィンドウ４１の一部が隠れる場合、隠れない部分（斜線箇所）４１Ｅ内に収まるサイズに変更しても良い。即ち、動画表示欄４１Ｂの縦横比を変えずに縮小した動画表示ウィンドウ４１の幅Ｗ３及び高さＨ３が、隠れない部分４１Ｅの幅Ｗ４及び高さＨ４以下となるようにサイズを決定する。 Furthermore, when the moving image display window is changed to a small size, the moving image display window is not limited to a fixed size, and may be changed to a size that does not overlap with the active window. For example, as shown in FIG. 10, when the moving image display window 41 is inactive, the other windows 42 are switched to active, and a part of the moving image display window 41 is hidden, the size is changed to fit within the non-hidden portion (shaded portion) 41E. You may do it. That is, the size is determined so that the width W3 and the height H3 of the moving image display window 41 reduced without changing the aspect ratio of the moving image display column 41B are equal to or less than the width W4 and the height H4 of the non-hidden portion 41E.
　更にまた、動画表示ウィンドウを小サイズに変更する場合、動画表示ウィンドウを移動して前記第２ウィンドウサイズ或は前記アクティブウィンドウと重ならないサイズに変更しても良い。例えば、図１１に示すように動画表示ウィンドウを所定位置（図１１では右上隅）或は所定方向に移動する。この所定位置及び所定方向は、予め記憶部１７に記憶（設定）させておく。なお、非アクティブへの切り替わり時に、動画表示ウィンドウの移動前の位置も記録しておき、アクティブに切り替わった場合に、この記録した元の位置へ戻す。 Furthermore, when the moving image display window is changed to a small size, the moving image display window may be moved and changed to a size that does not overlap the second window size or the active window. For example, as shown in FIG. 11, the moving image display window is moved in a predetermined position (upper right corner in FIG. 11) or in a predetermined direction. The predetermined position and the predetermined direction are stored (set) in the storage unit 17 in advance. Note that the position before moving of the moving image display window is also recorded at the time of switching to inactive, and when it is switched to active, the recorded original position is restored.
　〈実施形態２〉
　次に本発明に係る実施形態２について説明図する。本実施形態２は、前述の実施形態１と比べてウィンドウサイズの変更と共に音量の変更を行う点が異なっている。 <Embodiment 2>
Next, a second embodiment according to the present invention will be described. The second embodiment is different from the first embodiment in that the volume is changed together with the window size.
　なお、ハードウェア構成は、前述の実施形態１と同じであるので、同一の要素には同符号を付すなどして再度の説明を省略する。 Since the hardware configuration is the same as that of the first embodiment, the same elements are denoted by the same reference numerals and the description thereof is omitted.
　動画を表示させながら他の作業を行う場合、動画再生音は、ＢＧＭのように小さめの音量とするのが好ましい。即ち、動画を表示させながら他の作業を行う場合、動画のみを視聴する場合と比べて小音量としたい。 When performing other work while displaying a moving image, it is preferable that the moving image playback sound has a lower volume like BGM. In other words, when other work is performed while displaying a moving image, it is desired to reduce the volume compared to the case of viewing only the moving image.
　そこで、本実施形態２では、ウィンドウサイズの変更と共に音量の変更を自動的に行う。図１２は、アクティブウィンドウを切り替えた際、本実施形態２のコンピュータ１０がプログラムに従って実行する制御方法の説明図である。 Therefore, in the second embodiment, the volume is automatically changed together with the window size. FIG. 12 is an explanatory diagram of a control method executed by the computer 10 according to the second embodiment according to a program when the active window is switched.
　ユーザが、キーボードやマウスで動画の再生を選択する、或はリモコン１３Ｂのテレビボタン３１，ＤＶＤボタン３２，ネットＴＶボタン３３を選択すると、動画再生プログラム（テレビジョン再生アプリケーション２８Ａ、ＤＶＤ動画再生アプリケーション２８Ｂ、ネットワーク配信動画再生アプリケーション２８Ｃ）が起動し、該動画再生プログラムに従って動画再生部２１が生成した映像信号を表示制御部１６を介して動画表示ウィンドウに表示させる（ステップ１、以下Ｓ１のように略記する）。本実施形態においてウィンドウ状態検出部１４は、この動画再生部２１による映像信号を表示するウィンドウを動画表示ウィンドウとして判別する。また、これに限らずウィンドウ状態検出部１４は、所定の動画データの再生が選択された場合、例えば".mpg"や".avi"等の拡張子が付いたファイル、ストリーミングデータの再生が選択された場合に、このデータを表示しているウィンドウを動画表示ウィンドウと判別しても良い。 When the user selects playback of a moving image with the keyboard or mouse, or selects the TV button 31, the DVD button 32, or the net TV button 33 of the remote controller 13B, a moving image playback program (television playback application 28A, DVD video playback application 28B). , The network distribution video playback application 28C) is started, and the video signal generated by the video playback unit 21 in accordance with the video playback program is displayed on the video display window via the display control unit 16 (step 1, hereinafter abbreviated as S1). To do). In the present embodiment, the window state detection unit 14 determines a window for displaying a video signal by the moving image reproduction unit 21 as a moving image display window. Not limited to this, the window state detection unit 14 selects, for example, a file with an extension such as “.mpg” or “.avi”, or reproduction of streaming data when reproduction of predetermined moving image data is selected. In such a case, the window displaying this data may be determined as the moving image display window.
　そして、ウィンドウ状態検出部１４は、所定期間毎（本例では１００ｍｓ毎）に動画表示ウィンドウの状態の切り替わりが無いか、即ちポーリングにより動画表示ウィンドウのアクティブへの切り替わり或は非アクティブへの切り替わりを検出する（Ｓ２）。 Then, the window state detection unit 14 determines whether there is no switching of the state of the moving image display window every predetermined period (in this example, every 100 ms), that is, the switching of the moving image display window to active or inactive by polling. Detect (S2).
　この動画表示ウィンドウの切り替わりが無ければ待機し、動画表示ウィンドウの切り替わりが有った場合、ウィンドウ状態検出部１４は、動画表示ウィンドウがアクティブであるか否かを判定する（Ｓ３）。 If there is no switching of the moving image display window, the process waits. If there is a switching of the moving image display window, the window state detection unit 14 determines whether the moving image display window is active (S3).
　ここで、動画表示ウィンドウが非アクティブに切り替わったと判定した場合、ウィンドウ状態検出部１４は、更に、この切り替わりが、初めてであるか否かを判定する（Ｓ４）。例えば、この切り替わりが、動画表示プログラムのインストール後初めて或は動画表示プログラムの起動から終了までの間で初めてであるか否かを判定する。 Here, when it is determined that the moving image display window has been switched to inactive, the window state detection unit 14 further determines whether or not this switching is the first time (S4). For example, it is determined whether or not this switching is the first time after the installation of the moving image display program or the first time from the start to the end of the moving image display program.
　もし、初めて動画表示ウィンドウが非アクティブに切り替わったのであれば、音量制御部２３は、現在の動画再生音の音量を第１値として記憶部１７に記憶させる（Ｓ２１）。また、表示制御部１６は、現在の動画表示ウィンドウのサイズを第１ウィンドウサイズとして記憶部１７に記憶させる（Ｓ５）。 If the movie display window is switched to inactive for the first time, the volume control unit 23 stores the volume of the current movie playback sound as the first value in the storage unit 17 (S21). In addition, the display control unit 16 stores the current moving image display window size in the storage unit 17 as the first window size (S5).
　ステップ５の後或はステップ４で初めてでない場合、音量制御部２３は、前記動画再生音の音量を所定の小音量（第２値）に変更する（Ｓ２２）。ここで所定の第２値とは、後述のように動画表示ウィンドウが非アクティブのときの音量を予め記憶しておく。また、該第２値は、デフォルト値を設定しておいても良いし、ユーザが操作入力部１３で所望の音量を入力し、記憶部１７に記憶させて（設定して）おくものでも良い。 After Step 5 or when it is not the first time in Step 4, the volume control unit 23 changes the volume of the moving image playback sound to a predetermined small volume (second value) (S22). Here, the predetermined second value is stored in advance as the volume when the moving image display window is inactive as described later. The second value may be set as a default value, or may be stored (set) by the user inputting a desired volume with the operation input unit 13 and stored in the storage unit 17. .
　また、表示制御部１６は、該動画表示ウィンドウを所定の第２ウィンドウサイズに変更する（Ｓ６）。ここで所定の第２ウィンドウサイズとは、予めデフォルト値を設定しておいても良いし、ユーザが操作入力部１３で所望のサイズを入力し、記憶部１７に記憶させて（設定して）おくものでも良い。 The display control unit 16 changes the moving image display window to a predetermined second window size (S6). Here, the predetermined second window size may be set in advance as a default value, or the user inputs a desired size with the operation input unit 13 and stores (sets) it in the storage unit 17. You can leave it.
　なお、表示制御部１６は、動画表示ウィンドウを第２ウィンドウサイズに変更する際、ウィンドウのサイズだけを変更するのではなく、動画を縦横比を変えずにウィンドウサイズに合わせて縮小表示する。 In addition, when changing the moving image display window to the second window size, the display control unit 16 does not change only the size of the window, but reduces the moving image to the window size without changing the aspect ratio.
　また、ステップ４で動画表示ウィンドウの非アクティブへの切り替わりが初めてでない、即ち第１ウィンドウサイズが設定済み（記録済み）の場合、表示制御部１６は、第１ウィンドウサイズの記録を省略して動画表示ウィンドウを所定の第２ウィンドウサイズに変更する（Ｓ６）。 In addition, when the moving image display window is not switched to inactive for the first time in step 4, that is, when the first window size is already set (recorded), the display control unit 16 omits the recording of the first window size and displays the moving image. The display window is changed to a predetermined second window size (S6).
　一方、ステップ３で、動画表示ウィンドウがアクティブに切り替わったと判定された場合、音量制御部２３は、現在の動画再生音を第２値として記憶部１７に記憶させ（Ｓ２３）、該動画再生音の音量を標準音量（第１値）に変更する（Ｓ２４）。 On the other hand, when it is determined in step 3 that the moving image display window has been switched to active, the volume control unit 23 stores the current moving image playback sound in the storage unit 17 as the second value (S23), and The volume is changed to the standard volume (first value) (S24).
　また、表示制御部１６は、記憶部１７を参照し、動画表示ウィンドウを第１ウィンドウサイズに変更する（Ｓ７）。 The display control unit 16 refers to the storage unit 17 and changes the moving image display window to the first window size (S7).
　なお、上記フローでは、アクティブウィンドウを切り替えた際に、動画再生音の音量及び設定値（第１値及び第２値）を更新しているが、アクティブウィンドウを切り替え無いとき、即ち動画表示ウィンドウがアクティブのまま或は非アクティブのまま該動画再生音の音量及び設定値を更新することもできる。 In the above flow, when the active window is switched, the volume and setting values (first value and second value) of the moving image playback sound are updated. However, when the active window is not switched, that is, the moving image display window is displayed. It is also possible to update the volume and setting value of the moving image playback sound while remaining active or inactive.
　図１３は、アクティブウィンドウの切り替えなしに動画再生音の音量及び設定値を更新する処理の説明図である。 FIG. 13 is an explanatory diagram of processing for updating the volume and setting value of the moving image playback sound without switching the active window.
　動画表示プログラムを起動（Ｓ１）した後、音量制御部２３は、所定期間（本例では１００ｍｓ）毎に動画表示ウィンドウがアクティブか否かを判定する（Ｓ３２，Ｓ３３）。 After starting the moving image display program (S1), the volume control unit 23 determines whether or not the moving image display window is active every predetermined period (100 ms in this example) (S32, S33).
　そして、音量制御部２３は、音量変更の操作がされたか否かを検出し（Ｓ３４）、操作されていない場合にはステップ３２へ戻り、操作された場合には動画再生音を該操作に応じた音量に変更し（Ｓ３５）、この変更した音量を第１値として記憶部１７に記憶させる（Ｓ３６）。 Then, the volume control unit 23 detects whether or not a volume change operation has been performed (S34). If not, the process returns to step 32. The volume is changed (S35), and the changed volume is stored in the storage unit 17 as the first value (S36).
　一方、ステップ３３で、非アクティブと判定した場合、音量制御部２３は、音量変更の操作がされたか否かを検出し（Ｓ３７）、操作されていない場合にはステップ３２へ戻り、操作された場合には動画再生音を該操作に応じた音量に変更し（Ｓ３８）、この変更した音量を第２値として記憶部１７に記憶させる（Ｓ３９）。 On the other hand, if it is determined in step 33 that the volume is inactive, the volume controller 23 detects whether or not a volume change operation has been performed (S37). If the volume has not been operated, the process returns to step 32 and is operated. In this case, the moving image playback sound is changed to a volume corresponding to the operation (S38), and the changed volume is stored in the storage unit 17 as the second value (S39).
　なお、このように非アクティブ時の動画再生音の音量を変更する場合、マウス等の選択入力部１３Ａで動画表示ウィンドウを操作したのでは、動画表示ウィンドウがアクティブに切り替わってしまうので、リモコン等の特定入力部１３Ｂによって変更するのが望ましい。また、マウス等の選択入力部１３Ａであっても、動画表示ウィンドウ以外を開いてＯＳのマスタボリュームを変更する等の操作によって動画再生音の音量を変えるのであれば、動画表示ウィンドウが非アクティブの状態で音量を変更できる。 Note that when changing the volume of the video playback sound when inactive in this way, if the video display window is operated with the selection input unit 13A such as a mouse, the video display window is switched to an active state. It is desirable to change by specific input part 13B. In addition, even in the selection input unit 13A such as a mouse, if the volume of the moving image playback sound is changed by an operation such as opening a window other than the moving image display window and changing the master volume of the OS, the moving image display window is inactive. You can change the volume in the state.
　このように本実施形態によれば、ユーザが選択入力部１３でウィンドウを選択する等の操作を行った場合に、電子装置１０がアクティブウィンドウの切り替わりを検出して動画表示ウィンドウのサイズ及び動画再生音の音量を自動的に変更する。従って、文書作成やメールチェック等の主たる作業を行いながら動画を視聴する場合に、動画表示ウィンドウが隠れないように小さくしたり、小さくした動画表示ウィンドウを標準サイズに戻したり、動画再生音を小さくしたりするユーザの手間を軽減できる。 As described above, according to the present embodiment, when the user performs an operation such as selecting a window with the selection input unit 13, the electronic apparatus 10 detects the switching of the active window, and the size of the moving image display window and the moving image reproduction. Automatically change the sound volume. Therefore, when watching a movie while performing main work such as document creation and e-mail check, the movie display window is reduced so as not to be hidden, the reduced movie display window is returned to the standard size, or the movie playback sound is reduced. The user's trouble of performing can be reduced.
　〈変形例〉
　上記実施形態において、動画再生音の第１値と第２値は、第１値よりも第２値が小さければ、任意の値に設定して良い。 <Modification>
In the above embodiment, the first value and the second value of the moving image reproduction sound may be set to arbitrary values as long as the second value is smaller than the first value.
　また、図１３の例では、動画表示ウィンドウの非アクティブへの切り替わりが初めてであった場合に第１値を記録したが、これに限らずステップ４を省略して図１４に示すように、動画表示ウィンドウが非アクティブに変る度に第１ウィンドウサイズを記録するようにしても良い。 In the example of FIG. 13, the first value is recorded when the moving image display window is switched to inactive for the first time. However, the present invention is not limited to this, and step 4 is omitted, as shown in FIG. The first window size may be recorded each time the display window changes to inactive.
　更に、図１４のステップ５，２１，２３を省略して切り替え時に第１値及び第２値の記録を行うのではなく、予め設定した音量に変更する構成としても良い。例えば、図１３で設定した第１値又は第２値に変更する。 Furthermore, steps 5, 21 and 23 in FIG. 14 may be omitted, and the first value and the second value may not be recorded at the time of switching, but may be changed to a preset volume. For example, the value is changed to the first value or the second value set in FIG.
　なお、第２値は、図１３等で説明した絶対的な値に限らず、動画表示ウィンドウのアクティブ時の音量（第１値）に対して所定の割合で下げた（小さくした）音量となるように相対的な値を設定しても良い。 Note that the second value is not limited to the absolute value described with reference to FIG. 13 and the like, and is a volume that is lowered (decreased) at a predetermined rate with respect to the volume (first value) when the moving image display window is active. A relative value may be set as described above.
　例えば、第２値を１／２や１／３と設定した場合、動画表示ウィンドウがアクティブ時に第１値であった動画再生音の音量を非アクティブに切り替わった際に、１／２或は１／３に変更する。 For example, when the second value is set to 1/2 or 1/3, when the moving image playback sound volume is switched to inactive when the moving image display window is active, 1/2 or 1 Change to / 3.
　同様に、図１２の処理方法において、第２ウィンドウサイズを第１ウィンドウサイズに対する割合で設定し、ステップ２１のように、動画表示ウィンドウが非アクティブに切り替わった際、現在の音量（アクティブ時の音量）を第１値として記憶する場合、ステップ２２では動画再生音量をアクティブ時の音量から所定割合で下げた（小さくした）音量とする。 Similarly, in the processing method of FIG. 12, the second window size is set as a ratio to the first window size, and when the moving image display window is switched to inactive as in step 21, the current volume (the volume at the time of activation) is set. ) As the first value, in step 22, the moving image playback volume is set to a volume that is lowered (decreased) by a predetermined rate from the volume at the time of activation.
