When the insertion portion 131 of the support column 130 is inserted into the connection portion 117, the projection portion 132 engages with the hole 118 and the main body portion 110 is fixed to the support column 130. In a state where the main body 110 is fixed to the column 130, the main body 110 can be removed from the column 130 by pulling the main body 110 upward while pushing the protrusion 132 inward. Thus, in the present embodiment, the user can easily attach / remove the main body 110 to / from the support column 130 by hand without using a tool. Therefore, in some cases, the user can remove the main body 110 from the support 130 and place it at an arbitrary place to view the video. As shown in FIG. 2, since the input / output terminal 115 is disposed on the side surface of the main body 110, even when the main body 110 is placed on the floor so that the back surface of the main body 110 faces downward, Connection to the input / output terminal 115 of cables is possible. Therefore, the user can view the video even when the main body 110 is placed on the floor with the display screen 111 oriented horizontally.
　さらに、本実施形態に係る映像表示装置１００は、フレームシーケンシャル方式の立体表示に対応している。すなわち、映像表示装置１００は、対応するシャッター眼鏡とともにフレームシーケンシャル方式の映像表示システムを構成する。具体的に、映像表示装置１００は、右眼用画像及び左眼用画像を時分割で交互に切り替えて表示画面１１１に表示する。また、本体部１１０にはトランスミッター１１９が配置されており、このトランスミッター１１９が対応するシャッター眼鏡に対して画像切り替えのタイミングを知らせる信号を送出している。シャッター眼鏡は、この信号を受信して、表示画面１１１に右眼用画像が表示されている間は左眼用のシャッターを閉じ、左眼用画像が表示されている間は右眼用のシャッターを閉じる。これにより、シャッター眼鏡をかけたユーザは左眼で左眼用画像を、右眼で右眼用画像を、それぞれ見ることができる。 Furthermore, the video display device 100 according to the present embodiment is compatible with frame sequential 3D display. That is, the video display apparatus 100 constitutes a frame sequential video display system together with the corresponding shutter glasses. Specifically, the video display apparatus 100 displays the right-eye image and the left-eye image on the display screen 111 by alternately switching in time division. In addition, a transmitter 119 is disposed in the main body 110, and the transmitter 119 sends a signal informing the shutter glasses corresponding to the timing of image switching. The shutter glasses receive this signal and close the left-eye shutter while the right-eye image is displayed on the display screen 111, and the right-eye shutter while the left-eye image is displayed. Close. As a result, the user wearing the shutter glasses can view the left eye image with the left eye and the right eye image with the right eye.
　また、映像表示装置１００は、このようなフレームシーケンシャルの表示方式を利用して、複数のユーザのそれぞれに互いに異なる画像を視聴させることもできる。具体的に、映像表示装置１００は、右眼用画像及び左眼用画像の代わりに、ユーザＡ用の画像、及びユーザＢ用の画像を、交互に切り替えて表示画面１１１に表示する。また、トランスミッター１１９は、ユーザＡが使用するシャッター眼鏡、及びユーザＢが使用するシャッター眼鏡のそれぞれに対して、画像の切り替えタイミングを知らせる信号を送出する。この信号を受けて、ユーザＡが使用するシャッター眼鏡は、ユーザＢ用の画像が表示されている間両眼のシャッターを閉じ、ユーザＡ用の画像が表示されている間は両眼のシャッターを開ける。逆に、ユーザＢが使用するシャッター眼鏡は、ユーザＡ用の画像が表示されている間両眼のシャッターを閉じ、ユーザＢ用の画像が表示されている間は両眼のシャッターを開ける。こうすれば、二人のユーザが互いに全く別の映像を視聴することができる。 Also, the video display apparatus 100 can allow each of a plurality of users to view different images using such a frame sequential display method. Specifically, the video display device 100 alternately displays an image for the user A and an image for the user B on the display screen 111 instead of the image for the right eye and the image for the left eye. In addition, the transmitter 119 sends a signal notifying the switching timing of images to each of the shutter glasses used by the user A and the shutter glasses used by the user B. Upon receiving this signal, the shutter glasses used by the user A close the binocular shutter while the user B image is displayed, and the binocular shutter while the user A image is displayed. Open. Conversely, the shutter glasses used by the user B close the binocular shutter while the image for the user A is displayed, and open the binocular shutter while the image for the user B is displayed. In this way, two users can view videos that are completely different from each other.
　以下、本実施形態に係る映像表示装置１００の動作状態の遷移、及びこの状態遷移に伴うインジケーターの表示の具体例について、図４の状態遷移図を用いて説明する。 Hereinafter, a specific example of the transition of the operation state of the video display apparatus 100 according to the present embodiment and the display of the indicator accompanying the state transition will be described with reference to the state transition diagram of FIG.
　まず、電源が入っていない状態であっても、本体部１１０に対して電力供給が行われていれば、映像表示装置１００は電源インジケーター１１３を点灯させる。この状態を以下では待機状態Ｍ１という。このとき電源インジケーター１１３は、映像表示装置１００が待機状態Ｍ１にあることを表示するために、第１の色（例えば赤色）で点灯する。なお、この時点では状態表示インジケーター１１２は点灯しない。 First, even when the power is off, the video display device 100 turns on the power indicator 113 if power is supplied to the main body 110. Hereinafter, this state is referred to as a standby state M1. At this time, the power indicator 113 is lit in the first color (for example, red) in order to display that the video display device 100 is in the standby state M1. At this time, the status display indicator 112 is not lit.
　待機状態Ｍ１においてユーザが電源ボタンを押下すると、映像表示装置１００の電源がオンになり、映像表示装置１００は初期準備状態Ｍ２に移行する。この初期準備状態Ｍ２では、映像表示装置１００は外部からの映像信号の入力の有無を判定し、映像信号の入力があれば、当該映像信号に応じた映像を表示するための準備を行う。より具体的に、映像表示装置１００は、映像信号に含まれる同期信号の検出を行う。信号の同期がとれない間は、映像を正常に表示できないおそれがあるため、表示画面１１１による映像の表示は行われない。信号の同期が完了し、映像を表示する準備が整うと、映像表示装置１００は後述する映像表示状態Ｍ３に遷移する。一方、電源がオンになったときに外部からの映像信号の入力がない場合、映像表示装置１００は、映像信号の入力がない旨を知らせるメッセージを表示画面１１１に一定時間表示して、後述する省電力動作状態Ｍ４に遷移する。 When the user presses the power button in the standby state M1, the power of the video display device 100 is turned on, and the video display device 100 shifts to the initial preparation state M2. In the initial preparation state M2, the video display apparatus 100 determines whether or not an external video signal is input, and if there is an input of the video signal, prepares to display a video corresponding to the video signal. More specifically, the video display apparatus 100 detects a synchronization signal included in the video signal. While the signals cannot be synchronized, there is a possibility that the video cannot be displayed normally, so that the video is not displayed on the display screen 111. When the signal synchronization is completed and the video is ready to be displayed, the video display device 100 transitions to a video display state M3 described later. On the other hand, when there is no external video signal input when the power is turned on, the video display device 100 displays a message informing that there is no video signal input on the display screen 111 for a certain period of time, which will be described later. Transition to the power saving operation state M4.
　この初期準備状態Ｍ２の間、映像表示装置１００は、状態表示インジケーター１１２を点灯して、映像表示の準備中であることをユーザに知らせる表示を行う。具体的に、映像表示装置１００は、電源がオンになって待機状態Ｍ１から初期準備状態Ｍ２に遷移すると、状態表示インジケーター１１２を所定の色（例えば青色）で点灯させる。また、電源がオンになったことを示すために、電源インジケーター１１３は、待機状態Ｍ１を示す第１の色から、これとは異なる第２の色（例えば緑色）に発光色を変更する。 During the initial preparation state M2, the video display device 100 turns on the status display indicator 112 to display to the user that the video display is being prepared. Specifically, when the video display device 100 is turned on and transitions from the standby state M1 to the initial preparation state M2, the state display indicator 112 is lit in a predetermined color (for example, blue). In order to indicate that the power is turned on, the power indicator 113 changes the emission color from the first color indicating the standby state M1 to a second color different from the first color (for example, green).
　映像表示状態Ｍ３は、外部から入力される映像信号に基づいて表示画面１１１に映像を表示中の状態である。初期準備状態Ｍ２からこの映像表示状態Ｍ３に遷移すると、表示画面１１１による映像の表示が開始され、このタイミングで状態表示インジケーター１１２による表示は終了する（すなわち、状態表示インジケーター１１２が消灯する）。なお、電源インジケーター１１３は映像表示状態Ｍ３でもそのまま第２の色で点灯している。 The video display state M3 is a state in which a video is being displayed on the display screen 111 based on a video signal input from the outside. When the transition is made from the initial preparation state M2 to the video display state M3, the display of the video on the display screen 111 is started, and the display by the status display indicator 112 is terminated at this timing (that is, the status display indicator 112 is turned off). The power indicator 113 is lit in the second color as it is even in the video display state M3.
　省電力動作状態Ｍ４は、映像表示装置１００が省電力で動作している状態である。この状態では、映像表示装置１００の電源はオンになっているが、映像信号が入力されていないため、映像表示装置１００は表示画面１１１に何も表示せず、一部の回路への電力供給を停止する。電源インジケーター１１３は、映像表示装置１００が省電力動作状態Ｍ４に移行すると、通常動作状態を示す第２の色から、第１及び第２の色のいずれとも異なる第３の色（例えばオレンジ色）に発光色を変更する。なお、状態表示インジケーター１１２は、初期準備状態Ｍ２から省電力動作状態Ｍ４に移行した際にも消灯する。 The power saving operation state M4 is a state in which the video display device 100 is operating with power saving. In this state, the video display device 100 is turned on, but no video signal is input, so the video display device 100 does not display anything on the display screen 111 and supplies power to some circuits. To stop. When the video display device 100 shifts to the power saving operation state M4, the power indicator 113 changes from the second color indicating the normal operation state to a third color (for example, orange) that is different from both the first and second colors. Change the emission color to. The state display indicator 112 is also turned off when the initial preparation state M2 is shifted to the power saving operation state M4.
　映像表示状態Ｍ３又は省電力動作状態Ｍ４においてユーザが電源ボタンを押下すると、映像表示装置１００の電源はオフになる。このとき映像表示装置１００は、待機状態Ｍ１に遷移し、電源インジケーター１１３の発光色は第１の色に変更される。 When the user presses the power button in the video display state M3 or the power saving operation state M4, the video display device 100 is turned off. At this time, the video display device 100 transitions to the standby state M1, and the light emission color of the power indicator 113 is changed to the first color.
　映像表示状態Ｍ３において外部からの映像信号の入力が中断した場合、映像表示装置１００は映像信号の入力がない旨を知らせるメッセージを表示画面１１１に一定時間表示して、省電力動作状態Ｍ４に遷移する。また、省電力動作状態Ｍ４において映像信号の入力が開始された場合、映像表示装置１００は準備状態Ｍ５に遷移する。この準備状態Ｍ５において、映像表示装置１００は、初期準備状態Ｍ２と同様に、入力される映像信号に含まれる同期信号の検出を行う。そして、信号の同期が完了し、映像を表示する準備が整うと、映像表示装置１００は映像表示状態Ｍ３に遷移する。 When the input of an external video signal is interrupted in the video display state M3, the video display device 100 displays a message informing that there is no video signal input on the display screen 111 for a certain period of time, and transitions to the power saving operation state M4. To do. When the input of the video signal is started in the power saving operation state M4, the video display device 100 transitions to the preparation state M5. In this preparation state M5, the video display apparatus 100 detects a synchronization signal included in the input video signal, as in the initial preparation state M2. Then, when the signal synchronization is completed and preparation for displaying the video is completed, the video display device 100 transitions to the video display state M3.
　省電力動作状態Ｍ４から準備状態Ｍ５に遷移する際には、電源インジケーター１１３の発光色は第３の色から第２の色に戻り、映像表示装置１００が省電力動作状態Ｍ４から通常の動作状態になったことを表示する。しかしながら、初期準備状態Ｍ２の場合と異なり、映像表示の準備中であることを示す状態表示インジケーター１１２の表示は行わないこととする。省電力動作状態Ｍ４から準備状態Ｍ５への遷移は、ユーザがケーブルを映像入力端子に接続するなどのユーザのアクションを契機として発生するので、映像信号の入力があることがユーザにとって明らかだからである。 At the time of transition from the power saving operation state M4 to the preparation state M5, the light emission color of the power indicator 113 returns from the third color to the second color, and the video display device 100 changes from the power saving operation state M4 to the normal operation state. Is displayed. However, unlike the case of the initial preparation state M2, the state display indicator 112 indicating that the video display is being prepared is not displayed. This is because the transition from the power saving operation state M4 to the preparation state M5 is triggered by the user's action such as connecting the cable to the video input terminal, so that it is clear to the user that the video signal is input. .
　また、映像表示状態Ｍ３において表示中の映像の解像度が変更された場合、映像表示装置１００は再度映像信号の同期をとる必要がある。そのため、映像表示装置１００は準備状態Ｍ５に遷移し、解像度変更後の映像を表示する準備が整うと、映像表示状態Ｍ３に復帰する。この場合にも、解像度の変更は通常映像信号を入力する外部機器に対するユーザの何らかの指示に応じて行われるので、状態表示インジケーター１１２の表示は行わないこととする。 In addition, when the resolution of the video being displayed is changed in the video display state M3, the video display device 100 needs to synchronize the video signal again. For this reason, the video display device 100 transitions to the preparation state M5, and returns to the video display state M3 when preparation for displaying the video after the resolution change is completed. Also in this case, since the resolution change is performed according to some user instruction to the external device that inputs the normal video signal, the state display indicator 112 is not displayed.
　ここで、以上説明した状態遷移を実現するために映像表示装置１００が備える機能について、図５の機能ブロック図を用いて説明する。映像表示装置１００は、機能的に、電源制御部１５１と、同期検出部１５２と、映像表示制御部１５３と、電源インジケーター制御部１５４と、状態表示インジケーター制御部１５５と、を含んで構成される。これらの機能は、本体部１１１に内蔵される制御回路等によって実現される。 Here, the functions of the video display device 100 for realizing the state transition described above will be described with reference to the functional block diagram of FIG. The video display device 100 is functionally configured to include a power control unit 151, a synchronization detection unit 152, a video display control unit 153, a power indicator control unit 154, and a status display indicator control unit 155. . These functions are realized by a control circuit or the like built in the main body 111.
　電源制御部１５１は、映像表示装置１００の電源状態を管理する。具体的に、電源制御部１５１は、本体部１１１への電力供給が行われている間動作し、ユーザによる電源ボタンの操作を監視する。そして、ユーザが電源ボタンをオンにする操作を行った場合には、本体部１１１内の各部へ電力供給を行い、その動作を開始させる。また、ユーザが電源ボタンをオフにする操作を行った場合には、本体部１１１内の各部の動作を停止させる。さらに、電源ボタンがオンの状態で入出力端子１１５からの映像信号の入力がない場合には、本体部１１１を省電力状態Ｍ４に遷移させる制御を行う。さらに、省電力状態Ｍ４において映像信号の入力が開始された場合には、省電力状態Ｍ４から準備状態Ｍ５への遷移を指示する。さらに、本実施形態において電源制御部１５１は、電源状態の変化を電源インジケーター制御部１５４及び状態表示インジケーター制御部１５５に通知する。 The power control unit 151 manages the power state of the video display device 100. Specifically, the power control unit 151 operates while power is being supplied to the main body unit 111 and monitors the operation of the power button by the user. Then, when the user performs an operation of turning on the power button, power is supplied to each unit in the main body unit 111 to start its operation. When the user performs an operation to turn off the power button, the operation of each unit in the main body 111 is stopped. Furthermore, when the power button is on and no video signal is input from the input / output terminal 115, control is performed to shift the main body 111 to the power saving state M4. Further, when the input of the video signal is started in the power saving state M4, a transition from the power saving state M4 to the preparation state M5 is instructed. Further, in the present embodiment, the power supply control unit 151 notifies the power supply indicator control unit 154 and the state display indicator control unit 155 of the change in the power supply state.
　同期検出部１５２は、映像表示装置１００が初期準備状態Ｍ２又は準備状態Ｍ５に遷移した場合に、入出力端子１１５から入力される映像信号を受け付けて、当該映像信号の中に含まれる同期信号を検出する。本実施形態において、同期検出部１５２は、同期信号の検出が完了した際に、その旨を状態表示インジケーター制御部１５５に通知する。 When the video display device 100 transitions to the initial preparation state M2 or the preparation state M5, the synchronization detection unit 152 receives a video signal input from the input / output terminal 115 and outputs a synchronization signal included in the video signal. To detect. In the present embodiment, when the detection of the synchronization signal is completed, the synchronization detection unit 152 notifies the status display indicator control unit 155 to that effect.
　映像表示制御部１５３は、同期検出部１５２が検出した同期信号によって決定されるタイミングに基づいて映像信号を処理する。この映像信号の処理には、例えば色補正処理などが含まれてよい。さらに映像表示制御部１５４は、処理された映像信号に基づいて表示画面１１１に映像を表示する。 The video display control unit 153 processes the video signal based on the timing determined by the synchronization signal detected by the synchronization detection unit 152. This video signal processing may include, for example, color correction processing. Further, the video display control unit 154 displays a video on the display screen 111 based on the processed video signal.
　電源インジケーター制御部１５４は、電源制御部１５１が通知する電源状態の変化に応じて、電源インジケーター１１３の発光色を変化させる。具体的に、既に説明したように、電源インジケーター制御部１５４は、電源ボタンがオフの状態では電源インジケーター１１３を第１の色で点灯させる。そして、電源ボタンがオンになると電源インジケーター１１３を第２の色で点灯させ、本体部１１１が省電力動作状態Ｍ４に遷移すると電源インジケーター１１３を第３の色で点灯させる。 The power indicator control unit 154 changes the emission color of the power indicator 113 according to the change in the power state notified by the power control unit 151. Specifically, as already described, the power indicator control unit 154 lights the power indicator 113 in the first color when the power button is off. When the power button is turned on, the power indicator 113 is lit in the second color, and when the main body 111 is shifted to the power saving operation state M4, the power indicator 113 is lit in the third color.
　状態表示インジケーター制御部１５５は、電源制御部１５１から映像表示装置１００の電源がオンになった旨の通知を受けた場合（すなわち、映像表示装置１００が初期準備状態Ｍ２に遷移する場合）、状態表示インジケーター１１２を所定の色で点灯させる。また、同期検出部１５２から同期信号の検出終了の通知を受けた場合（すなわち、映像表示装置１００が初期準備状態Ｍ２から映像表示状態Ｍ３に遷移する場合）、状態表示インジケーター１１２を消灯する。また、電源制御部１５１が初期準備状態Ｍ２から省電力状態Ｍ４への遷移を通知した場合にも、状態表示インジケーター１１２を消灯させる。 When the state display indicator control unit 155 receives a notification from the power supply control unit 151 that the power of the video display device 100 is turned on (that is, when the video display device 100 transitions to the initial preparation state M2), the state display indicator control unit 155 The display indicator 112 is lit in a predetermined color. Further, when the notification of the end of detection of the synchronization signal is received from the synchronization detection unit 152 (that is, when the video display device 100 transitions from the initial preparation state M2 to the video display state M3), the state display indicator 112 is turned off. The state display indicator 112 is also turned off when the power supply control unit 151 notifies the transition from the initial preparation state M2 to the power saving state M4.
　以上説明したように、本実施形態では、電源インジケーター１１３は、待機状態Ｍ１（映像表示装置１００の電源がオフの状態）において第１の色で点灯し、省電力動作状態Ｍ４（映像表示装置１００が省電力で動作する状態）において第３の色で点灯し、それ以外の状態（映像表示装置１００の通常の動作状態）において第２の色で点灯する。これによって、電源インジケーター１１３は、映像表示装置１００の電源状態の変化を表示する。これに対して状態表示インジケーター１１２は、初期準備状態Ｍ２の間だけ、所定の色で点灯し、初期準備状態Ｍ２から他の状態に遷移する際に消灯する。これによりユーザは、表示画面１１１に何も表示されていない状態であっても、状態表示インジケーター１１２の表示によって映像表示装置１００は映像表示の準備中であることを把握できる。 As described above, in the present embodiment, the power indicator 113 is lit in the first color in the standby state M1 (the power of the video display device 100 is off), and the power saving operation state M4 (the video display device 100). Is lit in the third color in a state where the power is operated with power saving), and is lit in the second color in the other state (normal operation state of the video display device 100). As a result, the power indicator 113 displays a change in the power state of the video display device 100. On the other hand, the state display indicator 112 is lit in a predetermined color only during the initial preparation state M2, and is turned off when transitioning from the initial preparation state M2 to another state. Thereby, even if the user is in a state where nothing is displayed on the display screen 111, the user can grasp that the video display device 100 is preparing for video display by displaying the status display indicator 112.
　なお、以上の説明においては、準備状態Ｍ５では状態表示インジケーター１１２を点灯しないこととしたが、準備状態Ｍ５でも初期準備状態Ｍ２と同様に状態表示インジケーター１１２を点灯させることとしてもよい。この場合には、表示画面１１１に映像が表示されておらず、かつ、映像表示状態Ｍ３に遷移する可能性のある状態において状態表示インジケーター１１２が点灯することになる。そのためユーザは、現在は映像が表示されていないがこれから表示される可能性のある状態であることを状態表示インジケーター１１２の表示により判別できる。 In the above description, the state display indicator 112 is not lit in the preparation state M5. However, the state display indicator 112 may be lit in the preparation state M5 as in the initial preparation state M2. In this case, the state display indicator 112 is lit in a state where no video is displayed on the display screen 111 and there is a possibility of transition to the video display state M3. Therefore, the user can determine from the display of the status display indicator 112 that the video is not currently displayed but may be displayed in the future.
　また、以上の説明では、初期準備状態Ｍ２においては、映像信号の入力がない場合（一定時間後に省電力動作状態Ｍ４に遷移する場合）にも状態表示インジケーター１１２を点灯させることとしたが、このような場合には状態表示インジケーター１１２を点灯させず、映像信号が入力中の場合にのみ状態表示インジケーター１１２を点灯させることとしてもよい。こうすると、状態表示インジケーター１１２は映像信号の同期中に限って点灯することになり、ユーザは、状態表示インジケーター１１２による表示が行われているときには、必ずその後に映像が表示されると判断することができる。 Further, in the above description, in the initial preparation state M2, the state display indicator 112 is turned on even when there is no video signal input (when transitioning to the power saving operation state M4 after a certain time). In such a case, the state display indicator 112 may not be turned on, and the state display indicator 112 may be turned on only when a video signal is being input. In this way, the status display indicator 112 is lit only during the synchronization of the video signal, and the user always determines that the video is displayed after the status display indicator 112 is displayed. Can do.
　また、以上の説明においては、状態表示インジケーター１１２は初期準備状態Ｍ２において点灯し、それ以外の場合は消灯することによって、映像表示の準備中であることを表示することとしたが、状態表示インジケーター１１２は、他の方法でこのような表示を行ってもよい。例えば状態表示インジケーター１１２は、初期準備状態Ｍ２の間、点滅表示を行ってもよい。また、他の状態の間の発光色とは異なる色で点灯することとしてもよい。 In the above description, the state display indicator 112 is turned on in the initial preparation state M2 and is turned off in other cases to indicate that the video display is being prepared. 112 may perform such display in other ways. For example, the state display indicator 112 may perform blinking display during the initial preparation state M2. Moreover, it is good also as lighting with the color different from the luminescent color in another state.
　また、以上の説明においては、映像表示状態Ｍ３において電源インジケーター１１３は通常動作状態であることを示す第２の色で点灯することとしたが、映像表示状態Ｍ３においては電源インジケーター１１３を消灯することとしてもよい。映像表示状態Ｍ３では表示画面１１１に映像が表示されているので、映像表示装置１００が通常動作中であることは明らかだからである。 In the above description, the power indicator 113 is turned on in the second color indicating that it is in the normal operation state in the video display state M3. However, the power indicator 113 is turned off in the video display state M3. It is good. This is because it is clear that the video display device 100 is in normal operation since the video is displayed on the display screen 111 in the video display state M3.
　また、映像表示装置１００は、当該映像表示装置１００の動作モードに応じて、状態表示インジケーター１１２による表示を行うか否かを切り替えることとしてもよい。例えば映像表示装置１００は、通常の起動モードのほかに、高速起動モードを備える場合がある。この高速起動モードは、待機状態Ｍ１において電源ボタンが押下された際に、通常の起動モードより高速な映像表示装置１００の起動を実現するモードである。この高速起動モードは、待機状態Ｍ１でも通電されるメモリ内に映像表示装置１００の動作に必要な設定値を予め読み込んでおくなどの準備をすることによって実現できる。映像表示装置１００がこのような高速起動モードにある場合には、通常の起動モードよりも初期準備状態Ｍ２に留まる時間が短時間になり、その間にわざわざ映像表示の準備中であることを表示する必要性は少ない。そのため、映像表示装置１００は、高速起動モードで起動する際には、初期準備状態Ｍ２の間にも状態表示インジケーター１１２による表示を行わないこととしてもよい。 Also, the video display device 100 may switch whether or not to perform display by the status display indicator 112 according to the operation mode of the video display device 100. For example, the video display apparatus 100 may have a fast startup mode in addition to the normal startup mode. This high-speed start-up mode is a mode that realizes start-up of the video display device 100 faster than the normal start-up mode when the power button is pressed in the standby state M1. This high-speed startup mode can be realized by making preparations such as reading in advance a setting value necessary for the operation of the video display device 100 in the memory that is energized even in the standby state M1. When the video display device 100 is in such a high-speed startup mode, the time for staying in the initial preparation state M2 is shorter than that in the normal startup mode, and during that time, it is displayed that the video display is being prepared. There is little need. Therefore, the video display device 100 may not display the status display indicator 112 during the initial preparation state M2 when starting up in the fast startup mode.
