　コンピュータゲーム等のように、ユーザが表示映像を見ながら同時に入力操作を行う映像表示システムにおいて、ユーザが入力操作をするタイミングとユーザの入力操作に応じて変化する映像変化のタイミングとの時間差が大きいほど、ユーザは操作性が悪いという印象を受ける。このような映像表示システムでは、ユーザの入力操作に対し、即時に追従して映像が変化することが望ましく、ユーザが入力操作をするタイミングと映像変化のタイミングとの遅延時間がゼロであるものが理想である。 In a video display system in which a user performs an input operation while watching a display video, such as a computer game, the time difference between the timing when the user performs an input operation and the timing of a video change that changes according to the user's input operation is large The user gets the impression that the operability is bad. In such a video display system, it is desirable that the video changes immediately following the user's input operation, and the delay time between the timing when the user performs the input operation and the timing of the video change is zero. Ideal.
　しかし実際には、このような映像表示システムでは、ユーザの入力操作を受付けるコントローラと、その操作信号を受け演算処理をして映像信号を出力する演算装置と、その映像信号を受信し映像を表示する映像装置とのそれぞれにおいて処理に要する時間が発生する。すなわちそれらの合計が遅延時間となる。 However, in reality, in such a video display system, a controller that accepts a user's input operation, an arithmetic device that receives the operation signal and performs arithmetic processing and outputs a video signal, and receives the video signal and displays the video Time required for processing occurs in each of the video devices that perform the processing. That is, the sum of them becomes the delay time.
　このような映像表示システムにおいて、例えば、コントローラや映像装置等の個々の装置については遅延時間の評価がされている。また、操作部と表示部が一体型のゲーム機における操作遅延とその表示補正の技術がある（例えば、特許文献１参照）。 In such a video display system, for example, the delay time is evaluated for individual devices such as a controller and a video device. Further, there is a technique of operation delay and display correction in a game machine in which an operation unit and a display unit are integrated (see, for example, Patent Document 1).

　しかし、映像表示システムでは、コントローラ、演算装置、表示装置を異なる機器構成、及び異なる設定で使用することがあり、そのような場合、システム全体の遅延時間は変化する。そのため個々の装置の測定結果からシステム全体の遅延時間を評価できるとはいえないという問題があった。 However, in a video display system, a controller, a computing device, and a display device may be used with different device configurations and different settings. In such a case, the delay time of the entire system changes. For this reason, there is a problem that the delay time of the entire system cannot be evaluated from the measurement results of the individual devices.
　さらに、映像を同期させて実行する複数の映像表示システムでは、ユーザの入力操作から映像表示装置における映像変化が生じるまでの遅延時間に誤差が生じるおそれがある。この遅延時間の誤差による映像表示システムの応答性の違いがユーザ間の不公平感を生じさせるという問題があった。 Furthermore, in a plurality of video display systems that execute video in synchronization with each other, there is a possibility that an error may occur in the delay time from the user input operation until the video change occurs in the video display device. There is a problem that the difference in response of the video display system due to the error in the delay time causes unfairness among users.
　本発明は、上記の点に鑑みてなされたものであり、その目的は、ユーザの入力操作から映像表示装置における映像変化が生じるまでの映像表示システム全体にわたる遅延時間を考慮した映像表示システムを提供することにある。 The present invention has been made in view of the above points, and an object thereof is to provide a video display system that takes into account the delay time over the entire video display system from the user's input operation to the occurrence of a video change in the video display device.

　図２は、本発明の一実施形態に係る遅延時間検出システム２００が対象とする映像表示システムの構成例を示した図である。
　遅延時間検出システム２００が対象とする映像表示システムは、例えばビデオゲームのシステムであり、コントローラ１０と、演算装置１１と、映像表示装置１２とから構成される。
　コントローラ１０は、押ボタンスイッチ１０ａ，１０ｂ、及び十字スイッチ１０ｃを備える。これらのスイッチを操作スイッチと総称する。コントローラ１０は、ユーザによって操作スイッチ１０ａ，１０ｂ，及び１０ｃが押下されることにより、演算装置１１にユーザの操作に応じた信号を出力する。 FIG. 2 is a diagram illustrating a configuration example of a video display system targeted by the delay time detection system 200 according to an embodiment of the present invention.
The video display system targeted by the delay time detection system 200 is, for example, a video game system, and includes a controller 10, a calculation device 11, and a video display device 12.
The controller 10 includes pushbutton switches 10a and 10b and a cross switch 10c. These switches are collectively referred to as operation switches. The controller 10 outputs a signal corresponding to the operation of the user to the arithmetic device 11 when the operation switches 10a, 10b, and 10c are pressed by the user.
　演算装置１１は、コントローラ１０からの信号を入力する入力部と、実行するプログラムを記憶する記憶部と、ビデオゲームなどのプログラムを実行し、演算結果に基づいて信号を出力する制御演算部と、制御演算部からの信号に基づき映像表示装置１２に映像信号を出力する出力部を備える。
　この入力部は信号入力に対応するインタフェースだけでなく、ディップスイッチなどを含む各種、複数のスイッチを備え、それらのスイッチの組合せ操作により出力部から出力される映像信号に対して遅延時間の設定ができるようにしてもよい。 The computing device 11 includes an input unit that inputs a signal from the controller 10, a storage unit that stores a program to be executed, a control computation unit that executes a program such as a video game and outputs a signal based on the computation result; An output unit that outputs a video signal to the video display device 12 based on a signal from the control calculation unit is provided.
This input unit is equipped with not only an interface corresponding to signal input, but also various types of switches including dip switches, etc., and delay time can be set for the video signal output from the output unit by a combination operation of these switches. You may be able to do it.
　演算装置１１は、例えば、制御演算部が演算した結果を映像表示装置１２へ出力するタイミングを当該スイッチにより設定された時間に応じて遅延させて出力する。また、演算装置１１は、制御演算部が出力した結果を映像表示装置１２に出力するとともに、この映像信号を描画させるタイミングを遅延させる時間を指示する指示信号を出力するようにしてもよい。この指示信号はスイッチにより設定された時間に応じて決まる。すなわち、演算装置１１が備える入力部のスイッチを介して、映像表示システムに影響する信号処理のタイミングを調整する調整値が設定される。 The computing device 11 outputs, for example, the timing at which the result calculated by the control computing unit is output to the video display device 12 with a delay according to the time set by the switch. The arithmetic unit 11 may output the result output from the control arithmetic unit to the video display device 12, and may output an instruction signal for instructing a time for delaying the timing for drawing the video signal. This instruction signal is determined according to the time set by the switch. That is, an adjustment value for adjusting the timing of signal processing that affects the video display system is set via the switch of the input unit included in the arithmetic device 11.
　映像表示装置１２は、演算装置１１から入力される映像信号に基づき、映像表示を変化させる。
　すなわち、コントローラ１０のスイッチ操作により信号が入力されると、演算装置１１の処理を介して、映像表示装置１２の映像が変化する。 The video display device 12 changes the video display based on the video signal input from the arithmetic device 11.
That is, when a signal is input by operating the switch of the controller 10, the video of the video display device 12 changes through the processing of the arithmetic device 11.
　映像表示装置１２は、例えば液晶ディスプレイであり、制御演算部、映像処理部、表示部、入力部を備える。映像表示装置１２の制御演算部は、映像表示装置１２の各部を制御する。例えばＯＳＤ（Ｏｎ　Ｓｃｒｅｅｎ　Ｄｉｓｐｌａｙ）による設定プログラムを実行する。また、映像表示装置１２の制御演算部は記憶手段を有する。映像表示装置１２の映像処理部は、画像処理においてデータを一時的に保持するバッファメモリを備える。映像表示装置１２の表示部は、演算装置１１の出力部が出力する映像信号に基づき画像や文字、及びビデオゲーム操作画面などを表示する。映像表示装置１２の入力部は、映像信号等の信号入力部と、ＯＳＤの設定等に使用されるボタンスイッチ等を備える。ここで、映像表示装置１２の入力部には、遅延時間検出システム２００の時間差測定装置４１から出力される測定値などが入力されてもよい。 The video display device 12 is, for example, a liquid crystal display, and includes a control calculation unit, a video processing unit, a display unit, and an input unit. The control calculation unit of the video display device 12 controls each unit of the video display device 12. For example, a setting program by OSD (On Screen Display) is executed. Moreover, the control calculation part of the video display apparatus 12 has a memory | storage means. The video processing unit of the video display device 12 includes a buffer memory that temporarily holds data in image processing. The display unit of the video display device 12 displays images, characters, a video game operation screen, and the like based on the video signal output from the output unit of the arithmetic device 11. The input unit of the video display device 12 includes a signal input unit such as a video signal, a button switch used for setting an OSD, and the like. Here, a measurement value output from the time difference measurement device 41 of the delay time detection system 200 may be input to the input unit of the video display device 12.
　ここで、ＯＳＤにおいて、映像信号を受信してから表示するまでの遅延時間を調整する設定が行われるようにしてもよい。例えば、遅延時間を延ばすには、映像表示装置１２の映像処理部が備えるバッファメモリを使用して、映像表示装置１２の制御演算部に、画像処理においてデータを一時的に保持した後で出力する処理をさせる。この処理により遅延時間を調整し、例えばミリ秒単位で遅延時間を延ばすことができる。なお遅延時間の調整は、例えばＯＳＤから入力される調整値に基づいて映像表示装置１２の制御演算部が行う。 Here, in the OSD, a setting for adjusting the delay time from the reception of the video signal to the display may be performed. For example, in order to extend the delay time, the buffer memory provided in the video processing unit of the video display device 12 is used, and the data is temporarily stored in the image processing device and then output to the control calculation unit of the video display device 12. Let the process. By this processing, the delay time can be adjusted, and the delay time can be extended, for example, in milliseconds. The adjustment of the delay time is performed by the control calculation unit of the video display device 12 based on an adjustment value input from the OSD, for example.
　図３は、本発明の一実施形態に係る遅延時間検出システム２００の概略構成を示した図である。
　遅延時間検出システム２００は図３に示すように、操作検出装置２１と、映像変化検出装置３１と、時間差測定装置４１とを備える。 FIG. 3 is a diagram showing a schematic configuration of a delay time detection system 200 according to an embodiment of the present invention.
As shown in FIG. 3, the delay time detection system 200 includes an operation detection device 21, a video change detection device 31, and a time difference measurement device 41.
　なお、図３における遅延時間検出システム２００、操作検出装置２１、映像変化検出装置３１、時間差測定装置４１、コントローラ１０、演算装置１１、及び映像表示装置１２は、図１における遅延時間検出システム１、操作検出装置２、映像変化検出装置３、時間差測定装置４、コントローラ５、演算装置６、及び映像表示装置７にそれぞれ対応している。 Note that the delay time detection system 200, the operation detection device 21, the video change detection device 31, the time difference measurement device 41, the controller 10, the arithmetic device 11, and the video display device 12 in FIG. The operation detection device 2, the image change detection device 3, the time difference measurement device 4, the controller 5, the arithmetic device 6, and the video display device 7 are respectively supported.
　操作検出装置２１は、押ボタンスイッチ２１ａを備える。例えば、コントローラ１０が備える押ボタンスイッチ１０ｂが操作検出装置２１の押ボタンスイッチで押下されることにより、両方の押ボタンスイッチが同時に押下され、そのタイミングで操作検出装置２１は検出信号を時間差測定装置４１に出力する。 The operation detection device 21 includes a push button switch 21a. For example, when the push button switch 10b included in the controller 10 is pushed by the push button switch of the operation detection device 21, both push button switches are pushed simultaneously, and at that timing, the operation detection device 21 sends the detection signal to the time difference measuring device. 41 is output.
　なお、コントローラ１０の押ボタンスイッチ１０ａ，１０ｂ、及び十字スイッチ１０ｃと、操作検出装置２１の押ボタンスイッチ２１ａとは、スイッチの動作特性が近いほど、操作スイッチからの入力操作による信号が検出されるタイミングが近づく。すなわち、コントローラ１０が備える操作スイッチに対する入力操作が検出されるタイミングと、操作検出装置２１が備える押ボタンスイッチ２１ａに対する入力操作が検出されるタイミングとの時間差が小さくなる。 The push button switches 10a and 10b and the cross switch 10c of the controller 10 and the push button switch 21a of the operation detecting device 21 detect a signal due to an input operation from the operation switch as the switch operating characteristics are closer. The timing approaches. That is, the time difference between the timing at which an input operation on the operation switch included in the controller 10 is detected and the timing at which the input operation on the push button switch 21a included in the operation detection device 21 is detected becomes small.
　そのため、操作検出装置２１の押ボタンスイッチは、操作荷重やストローク等の動作特性を調整できることが望ましい。具体的には、コントローラ１０の入力信号と操作検出装置２１の入力信号とが検出されるタイミングの許容誤差が、後述の映像変化検出装置３１における許容誤差と同様にミリ秒オーダ以下であるように、操作検出装置２１の押ボタンスイッチ２１ａの動作特性が調整されればよい。 Therefore, it is desirable that the push button switch of the operation detection device 21 can adjust operation characteristics such as operation load and stroke. Specifically, the allowable error of the timing at which the input signal of the controller 10 and the input signal of the operation detecting device 21 are detected is set to be less than or equal to the millisecond order, similar to the allowable error in the video change detecting device 31 described later. The operation characteristics of the push button switch 21a of the operation detection device 21 may be adjusted.
　上述の方法を用いることで、コントローラ１０自体は操作スイッチの入力操作における信号を検出する機能を備えてないにもかかわらず、操作検出装置２１によりコントローラ１０の入力操作の信号を検出することができる。
　すなわち、従来は遅延時間を測定する際にはコントローラを分解し、検出信号を取り出すための配線を追加する等の難しい改造をしなくてはならない問題があったが、上述の方法により、コントローラを改造することなく操作スイッチの検出信号を取り出すことができる。 By using the above-described method, the operation detection device 21 can detect the input operation signal of the controller 10 even though the controller 10 itself does not have a function of detecting a signal in the input operation of the operation switch. .
That is, in the past, when measuring the delay time, there was a problem that the controller had to be disassembled and a difficult modification such as adding wiring for taking out the detection signal had to be made. The detection signal of the operation switch can be taken out without modification.
　映像変化検出装置３１は、ミリ秒オーダで映像の変化を検出することができるカラーセンサを備え、時間差測定装置４１に検出信号を出力する。ここで、ミリ秒オーダとは、例えば、信号が検出されるまでの応答時間が１ミリ秒以下という仕様を満たすようなセンサ仕様とする。なお、センサは、映像の変化を検出することができればモノクロの輝度センサでも良い。 The video change detection device 31 includes a color sensor that can detect a video change in the order of milliseconds, and outputs a detection signal to the time difference measurement device 41. Here, the millisecond order is, for example, a sensor specification that satisfies a specification that a response time until a signal is detected is 1 millisecond or less. The sensor may be a monochrome luminance sensor as long as it can detect a change in video.
　時間差測定装置４１は、操作検出装置２１から検出信号が入力されるタイミングと、映像変化検出装置３１から検出信号が入力されるタイミングとの差分を算出し、ユーザの操作に対する映像変化の遅延時間として出力する。
　出力方法は、例えば、時間差測定装置４１が備える表示部に、操作検出装置２１と映像変化検出装置３１との入力信号のタイミングチャート及び算出された遅延時間を表示する。 The time difference measuring device 41 calculates a difference between the timing at which the detection signal is input from the operation detection device 21 and the timing at which the detection signal is input from the video change detection device 31, and as a delay time of the video change with respect to the user operation. Output.
As an output method, for example, a timing chart of input signals of the operation detection device 21 and the video change detection device 31 and a calculated delay time are displayed on a display unit included in the time difference measurement device 41.
　本実施例では、時間差測定装置４１がタイマ機能を備えており、操作検出装置２１から検出信号が入力されるとカウントを開始し、映像変化検出装置３１から検出信号が入力されるとカウントを停止し、カウント停止時の経過時間を映像表示システムの遅延時間として出力する例を説明する。 In this embodiment, the time difference measuring device 41 has a timer function, and starts counting when a detection signal is input from the operation detection device 21, and stops counting when a detection signal is input from the video change detection device 31. An example in which the elapsed time when the count is stopped is output as the delay time of the video display system will be described.

　入力部２２は、押ボタンスイッチ２１ａを有し、押ボタンスイッチ２１ａが押下された際の信号を検出部２３に送る。
　検出部２３は、入力部２２から受けた信号を検出し、時間差測定装置４１の入力部４５に検出信号を出力する。 FIG. 4 is an electrical block diagram of a delay time detection system 200 according to an embodiment of the present invention.
The delay time detection system 200 includes an operation detection device 21, a video change detection device 31, and a time difference measurement device 41.
The operation detection device 21 includes an input unit 22 and a detection unit 23.
The input unit 22 includes a push button switch 21 a and sends a signal when the push button switch 21 a is pressed to the detection unit 23.
The detection unit 23 detects a signal received from the input unit 22 and outputs a detection signal to the input unit 45 of the time difference measuring device 41.
　映像変化検出装置３１は、入力部３２、検出部３３を有する。
　入力部３２は、映像変化検出装置３１が有するカラーセンサが映像の変化を認識した際の信号を検出部３３に出力する。
　検出部３３は、入力部３２から入力された信号を検出し時間差測定装置４１の入力部４５に検出信号を出力する。 The video change detection device 31 includes an input unit 32 and a detection unit 33.
The input unit 32 outputs a signal when the color sensor included in the video change detection device 31 recognizes a video change to the detection unit 33.
The detection unit 33 detects a signal input from the input unit 32 and outputs a detection signal to the input unit 45 of the time difference measuring device 41.
　時間差測定装置４１は、演算部４２、記憶部４３、表示部４４、入力部４５を有する。
　演算部４２は、処理に必要な演算を行う。具体的には、操作検出装置２１から検出信号を受け取ると遅延時間のカウントを開始する。そして、映像変化検出装置３１から検出信号を受け取るとカウントを終了し、遅延時間を算出する。
　記憶部４３は、演算部４２によって実行されるプログラムを予め記憶し、また、演算で使用されるデータを一時的に記憶する。
　表示部４４は、画像や文字などを表示し、通知部としても機能する。例えば、時間差測定装置４１に入力される検出信号のタイミングチャートや算出された遅延時間を表示し、ユーザへ通知する。 The time difference measuring device 41 includes a calculation unit 42, a storage unit 43, a display unit 44, and an input unit 45.
The calculation unit 42 performs calculations necessary for processing. Specifically, when a detection signal is received from the operation detection device 21, counting of the delay time is started. Then, when the detection signal is received from the video change detection device 31, the count is finished and the delay time is calculated.

The display unit 44 displays images, characters, and the like, and also functions as a notification unit. For example, the timing chart of the detection signal input to the time difference measuring device 41 and the calculated delay time are displayed and notified to the user.
　なお、図４には図示していないが、時間差測定部４１が出力部を備え、外部の装置、例えば映像表示装置１２あるいは演算装置１１に遅延時間の測定結果を出力するようにしてもよい。
　また、時間差測定装置４１を映像表示装置１２に内蔵してもよい。この場合は、映像表示装置１２の入力部に操作検出信号、映像変化検出信号および所定の遅延時間を示す調整値を入力し、測定結果を表示することができるとともに、測定結果よりもさらに遅延時間を増やして表示を遅延させることができる。 Although not shown in FIG. 4, the time difference measurement unit 41 may include an output unit, and the delay time measurement result may be output to an external device such as the video display device 12 or the arithmetic device 11.
Further, the time difference measuring device 41 may be built in the video display device 12. In this case, an operation detection signal, a video change detection signal, and an adjustment value indicating a predetermined delay time can be input to the input unit of the video display device 12 to display the measurement result, and the delay time is further longer than the measurement result.

　遅延時間検出システム２００が対象とする映像表示システムは、操作検出装置２１の押ボタンスイッチによりコントローラ１０が操作されると、演算装置１１を介し信号が処理され、その結果映像表示装置１２に生じる所定の映像変化が映像変化検出装置３１によって検出される。 In the video display system targeted by the delay time detection system 200, when the controller 10 is operated by the push button switch of the operation detection device 21, a signal is processed through the arithmetic device 11, and as a result, a predetermined signal generated in the video display device 12. Are detected by the image change detecting device 31.
　ここで、本実施形態における遅延時間検出システム２００が備える時間差測定装置４１が測定する遅延時間について説明する。
　図５は、本発明の一実施形態に係る遅延時間検出システム２００が備える時間差測定装置４１が測定する遅延時間について説明する図である。
　まず、コントローラ１０からユーザによる入力操作が行われ、コントローラ１０が操作スイッチから入力された信号を検出する際に、第１の遅延時間Ｔａが生じる。例えば、コントローラ１０が信号を検出するサンプリング周波数が６０Ｈｚであった場合、最大で１６．６ｍｓの遅延時間が生じる。 Here, the delay time measured by the time difference measuring device 41 included in the delay time detection system 200 in the present embodiment will be described.
FIG. 5 is a diagram illustrating the delay time measured by the time difference measuring device 41 included in the delay time detection system 200 according to an embodiment of the present invention.
First, when a user performs an input operation from the controller 10 and the controller 10 detects a signal input from the operation switch, a first delay time Ta occurs. For example, when the sampling frequency at which the controller 10 detects a signal is 60 Hz, a maximum delay time of 16.6 ms occurs.
　次に、演算装置１１が、コントローラ１０から出力された信号を受信し、所定の演算処理を行った上で映像信号を映像表示装置１２に出力する。このときの処理に要する時間が第２の遅延時間Ｔｂである。
　そして、映像表示装置１２は、演算装置１１からの映像信号を受け取り、所定の画像処理を行った上で映像として表示する。例えば、Ｉ／Ｐ変換、オーバードライブ、動き補間など複数のフレームの情報を用いる画像処理を含め、映像信号を受け取り、映像として表示するまでには一定の処理時間が必要となる。このときの処理に要する時間が第３の遅延時間Ｔｃである。 Next, the arithmetic device 11 receives the signal output from the controller 10, performs a predetermined arithmetic processing, and then outputs a video signal to the video display device 12. The time required for the processing at this time is the second delay time Tb.
Then, the video display device 12 receives the video signal from the arithmetic device 11, performs predetermined image processing, and displays it as a video. For example, a certain processing time is required until a video signal is received and displayed as a video image including image processing using information of a plurality of frames such as I / P conversion, overdrive, and motion interpolation. The time required for the processing at this time is the third delay time Tc.
　映像表示システムにおいては、ユーザは、入力操作のタイミングから映像変化のタイミングまでの時間を遅延時間として認識するため、図５に示すように、この映像表示システム全体の遅延時間をＴｓとすれば、Ｔｓ＝Ｔａ＋Ｔｂ＋Ｔｃとなる。
　本発明では、操作検出信号と映像変化検出信号との時間差を算出し、このＴｓを算出する。 In the video display system, since the user recognizes the time from the timing of the input operation to the timing of the video change as the delay time, as shown in FIG. 5, if the delay time of the entire video display system is Ts, Ts = Ta + Tb + Tc.
In the present invention, the time difference between the operation detection signal and the video change detection signal is calculated, and this Ts is calculated.
　ここで、本実施形態における遅延時間検出システム２００の動作について図６、図７を用いて説明する。
　図６は、本発明の一実施形態に係る遅延時間検出システム２００の動作について説明する第一の図である。
　まず、ユーザにより操作検出装置２１の押ボタンスイッチでコントローラ１０のボタン、図６の例では押ボタンスイッチ１０ｂを押下する。この操作により、時間差測定装置４１は、操作検出装置２１からの検出信号を受け、遅延時間の測定を開始する。また、時間差測定装置４１は表示部に検出信号のタイミングチャートを表示する。
　上述のコントローラ１０の押ボタンスイッチからの入力操作において、コントローラ１０が信号を検出する際に第１の遅延時間Ｔａが生じる。
　演算装置１１は、コントローラ１０からの信号に基づき演算を行い、映像表示装置１２に信号を出力する。この演算処理の際に第２の遅延時間Ｔｂが生じる。 Here, the operation of the delay time detection system 200 in the present embodiment will be described with reference to FIGS.
FIG. 6 is a first diagram for explaining the operation of the delay time detection system 200 according to the embodiment of the present invention.
First, the user presses the button of the controller 10 with the push button switch of the operation detection device 21, and in the example of FIG. 6, the push button switch 10b is pressed. By this operation, the time difference measuring device 41 receives the detection signal from the operation detecting device 21 and starts measuring the delay time. The time difference measuring device 41 displays a timing chart of the detection signal on the display unit.
In the input operation from the pushbutton switch of the controller 10 described above, a first delay time Ta occurs when the controller 10 detects a signal.
The arithmetic device 11 performs an operation based on a signal from the controller 10 and outputs a signal to the video display device 12. A second delay time Tb occurs during this calculation process.
　図７は、本発明の一実施形態に係る遅延時間検出システム２００の動作について説明する第二の図である。
　映像表示装置１２は、演算装置１１からの信号を受信し、画像処理を介し変化した映像を出力する。この画像処理と、該画像処理により得られた映像の出力との際に第３の遅延時間Ｔｃが生じる。 FIG. 7 is a second diagram for explaining the operation of the delay time detection system 200 according to the embodiment of the present invention.
The video display device 12 receives a signal from the arithmetic device 11 and outputs a changed video through image processing. A third delay time Tc occurs during the image processing and the output of the video obtained by the image processing.
　映像変化検出装置３１は、映像表示装置１２の映像変化を検出し、時間差測定装置４１に検出信号を出力する。
　時間差測定装置４１は、映像変化検出装置３１から検出信号を受けると遅延時間のカウントを終了し、映像表示システムの遅延時間Ｔｓを算出する。また、算出結果の遅延時間Ｔｓの値と検出信号のタイミングチャートを表示部に表示する。 The video change detection device 31 detects a video change of the video display device 12 and outputs a detection signal to the time difference measurement device 41.
When receiving the detection signal from the video change detecting device 31, the time difference measuring device 41 ends the delay time counting and calculates the delay time Ts of the video display system. Further, the value of the delay time Ts of the calculation result and the timing chart of the detection signal are displayed on the display unit.
　なお、上述の説明では遅延時間検出システム２００での信号処理、演算処理の遅延時間を考慮していないが、該遅延時間が映像表示システムにおいて許容され得る予め定められた値以下であれば無視してよい。また、該遅延時間が許容され得る値より大きい場合は、遅延時間の算出処理において遅延時間検出システム２００の遅延時間を差し引く補正処理を行う。 In the above description, the delay time of signal processing and arithmetic processing in the delay time detection system 200 is not considered, but is ignored if the delay time is equal to or less than a predetermined value that can be allowed in the video display system. It's okay. When the delay time is larger than an allowable value, a correction process for subtracting the delay time of the delay time detection system 200 is performed in the delay time calculation process.
　なお、上述の遅延時間検出システム２００での信号処理の遅延時間は、操作検出装置２１が入力操作を検出してから、映像変化検出装置３１が映像変化を検出し、時間差測定装置４１が遅延時間を出力するまでの一連の処理における時間差測定装置４１の演算処理を除いた処理に含まれる。
　上述の遅延時間検出システム２００での演算処理の遅延時間は、時間差測定装置４１の演算処理に含まれる。
　なお、映像表示システムにおいて許容され得る予め定められた基準を満たす遅延時間は、例えば、ミリ秒オーダ以下、具体的には１ミリ秒以下といった値としてもよい。 Note that the signal processing delay time in the above-described delay time detection system 200 is such that the video change detection device 31 detects a video change after the operation detection device 21 detects an input operation, and the time difference measurement device 41 detects the delay time. Is included in the processing excluding the arithmetic processing of the time difference measuring device 41 in a series of processing until the output of.
The delay time of the arithmetic processing in the delay time detection system 200 described above is included in the arithmetic processing of the time difference measuring device 41.
Note that the delay time satisfying a predetermined criterion that can be allowed in the video display system may be a value of, for example, the order of milliseconds or less, specifically, 1 millisecond or less.
　図８は、本発明の一実施形態に係る遅延時間検出システムの遅延時間検出処理について説明するためのフローチャートである。
　まず、操作検出装置２１の押ボタンスイッチ２１ａによりコントローラ１０のいずれかの操作スイッチが押下される（ステップＳ１０１）。
　操作検出装置２１は、押ボタンスイッチ２１ａ押下による検出信号を時間差測定装置４１に出力する（ステップＳ１０２）。
　時間差測定装置４１は、操作検出装置２１から検出信号が入力されると遅延時間のカウントを開始する（ステップＳ１０３）。 FIG. 8 is a flowchart for explaining the delay time detection process of the delay time detection system according to the embodiment of the present invention.
First, one of the operation switches of the controller 10 is pressed by the push button switch 21a of the operation detection device 21 (step S101).
The operation detection device 21 outputs a detection signal when the pushbutton switch 21a is pressed to the time difference measurement device 41 (step S102).
The time difference measuring device 41 starts counting the delay time when the detection signal is input from the operation detecting device 21 (step S103).
　映像変化検出装置３１のカラーセンサにより映像表示装置１２の映像変化を検出する（ステップＳ１０４）。
　映像変化検出装置３１は、時間差測定装置４１に検出信号を出力する（ステップＳ１０５）。
　時間差測定装置４１は、映像変化検出装置３１から検出信号が入力されると遅延時間のカウントを終了する（ステップＳ１０６）。
　時間差測定装置４１は、遅延時間を算出し表示部に出力し（ステップＳ１０７）、処理を終了する。 The video change of the video display device 12 is detected by the color sensor of the video change detection device 31 (step S104).
The video change detection device 31 outputs a detection signal to the time difference measurement device 41 (step S105).
The time difference measuring device 41 finishes counting the delay time when the detection signal is input from the video change detecting device 31 (step S106).
The time difference measuring device 41 calculates the delay time and outputs it to the display unit (step S107), and ends the process.
　以上より、本実施形態における遅延時間検出システム２００によれば、映像表示システムにおいてコントローラからの入力操作に対する映像表示装置において映像変化が生じる遅延時間を測定することが可能となる。すなわち、映像表示システム全体での入力操作に対する映像変化の出力までの遅延時間を測定することができる。
　また、映像表示システムの構成機器の改造や測定用機器の追加をすることなく、入力操作に対する映像変化の出力までの遅延時間を測定することができる。 As described above, according to the delay time detection system 200 in the present embodiment, it is possible to measure a delay time in which a video change occurs in the video display device in response to an input operation from the controller in the video display system. That is, it is possible to measure the delay time until the output of the video change with respect to the input operation in the entire video display system.
Further, it is possible to measure the delay time until the output of the video change with respect to the input operation without modifying the constituent devices of the video display system or adding the measuring device.
　上述の実施形態では、操作検出装置２１は押ボタンスイッチでの入力操作を検出する方法を説明した。しかし、入力操作は押ボタンスイッチに限らない。例えば、コントローラ１０がタッチパネルによる入力操作を受付ける場合、操作検出装置２１がタッチパネルの入力操作を検出できるセンサを備えることで入力操作の検出ができるようにしてもよい。 In the above-described embodiment, the operation detection device 21 has described the method for detecting the input operation with the push button switch. However, the input operation is not limited to a push button switch. For example, when the controller 10 accepts an input operation on the touch panel, the operation detection device 21 may be provided with a sensor that can detect the input operation on the touch panel so that the input operation can be detected.
　上述の実施形態では、映像変化検出装置３１は、外付けの装置であったが、映像表示装置１２に付随する構成としてもよい。また、時間差測定装置４１も映像表示装置１２に付随される構成としてもよい。その場合、遅延時間の検出結果をもとに映像表示装置１２が画像処理の制御をするようにしてもよい。 In the above-described embodiment, the video change detection device 31 is an external device, but may be configured to accompany the video display device 12. Further, the time difference measuring device 41 may be attached to the video display device 12. In that case, the video display device 12 may control the image processing based on the detection result of the delay time.
　また、上述の実施形態では、時間差測定装置４１は、システムを構成する装置の一つとして存在する例を説明したが、これに限らない。例えば、操作検出装置２１、または映像変化検出装置３１のいずれかに内蔵される構成であってもよい。 In the above-described embodiment, the example in which the time difference measuring device 41 exists as one of the devices constituting the system has been described. However, the present invention is not limited to this. For example, the structure incorporated in either the operation detection apparatus 21 or the image | video change detection apparatus 31 may be sufficient.
　また、上述の実施形態では、１組の映像表示システムの遅延時間を測定する場合を説明した。しかし、これに限らず、２組以上の映像表示システムの映像を同期させて使用するような場合、測定した遅延時間の結果をさらに活用することができる。ここで、２組以上の映像表示システムを同期させて使用するような例として、ネットワーク接続されたオンラインコンピュータゲームがあげられる。
　例として、映像表示システムを、ボクシング対戦ゲームのようなネットワーク接続された２組のコンピュータゲームシステムとする。各映像表示システムにおけるシステム全体の入出力には遅延時間が生じるが、映像表示システム毎の該遅延時間は機器構成や設定の違いにより必ずしも同じではなく、差が生じる可能性がある。 In the above-described embodiment, the case where the delay time of a set of video display systems is measured has been described. However, the present invention is not limited to this, and when the images of two or more sets of video display systems are used in synchronization, the result of the measured delay time can be further utilized. Here, an example of using two or more sets of video display systems in synchronization is an online computer game connected to a network.
As an example, assume that the video display system is two sets of networked computer game systems such as a boxing battle game. Although a delay time occurs in input / output of the entire system in each video display system, the delay time for each video display system is not necessarily the same due to a difference in device configuration and setting, and a difference may occur.
　例えば、ユーザが入力としてコントローラ１０の押ボタンスイッチ１０ｂを押下すると映像表示装置１２の画面上で出力としてボクサーがパンチを繰り出すようなオンラインボクシング対戦ゲームの場合、対戦するそれぞれのユーザがコントローラ１０の押ボタンスイッチ１０ｂを押下してから画面上で自身が操作する対象のボクサーがパンチを繰り出すまでの遅延時間には差が生じる可能性がある。 For example, in an online boxing battle game where a boxer punches as an output on the screen of the video display device 12 when the user depresses the pushbutton switch 10b of the controller 10 as an input, each user who competes presses the controller 10 There may be a difference in the delay time from when the button switch 10b is pressed until the target boxer to be operated on the screen starts punching.
　ここで、２組のコンピュータゲームシステムを、第１の映像表示システムと第２の映像表示システムとして説明を行う。なお、遅延時間は、遅延時間検出システム（遅延時間検出手段）２００によって測定された値であり、測定した遅延時間を遅延時間検出システムから映像表示システムへ入力する方法は問わない。例えば、各システムの入出力部を介した受け渡しが行われる。
　まず、第１の映像表示システムにおいて、コントローラ１０が備える操作スイッチ１０ａ，１０ｂ，１０ｃに入力操作が行われるタイミングと、該入力操作に基づき演算装置を介して映像が変化する映像表示装置の映像変化のタイミングとを遅延時間Ａとする。
　次に、第２の映像表示システムにおいて、コントローラ１０が備える操作スイッチ１０ａ，１０ｂ，１０ｃに入力操作が行われるタイミングと、該入力操作に基づき演算装置を介して映像が変化する映像表示装置の映像変化のタイミングとを遅延時間Ｂとする。
　遅延時間Ａと遅延時間Ｂとは必ずしも同じではなく、その差分をＮとする。 Here, two sets of computer game systems will be described as a first video display system and a second video display system. The delay time is a value measured by the delay time detection system (delay time detection means) 200, and the method for inputting the measured delay time from the delay time detection system to the video display system is not limited. For example, delivery is performed via the input / output unit of each system.
First, in the first video display system, the timing at which an input operation is performed on the operation switches 10a, 10b, and 10c included in the controller 10, and the video change of the video display device in which the video changes via the arithmetic device based on the input operation Is the delay time A.
Next, in the second video display system, the timing at which an input operation is performed on the operation switches 10a, 10b, and 10c included in the controller 10, and the video of the video display device in which the video changes via the arithmetic device based on the input operation The change timing is defined as a delay time B.
The delay time A and the delay time B are not necessarily the same, and the difference is N.
　ここで、遅延時間を活用する方法を説明する。第１の映像表示システムの遅延時間がＡミリ秒、第２の映像表示システムの遅延時間がＢミリ秒（Ａ＜Ｂ）であった場合、第１の映像表示システムの遅延時間が（Ａ＋Ｎ）ミリ秒（Ｎ＝Ｂ－Ａ）となるように、例えば映像表示装置１２が備えるＯＳＤから入力された設定情報が映像表示装置１２の制御演算部の記憶手段に書込まれる。その設定情報に基づいて映像表示システム全体として動作する。それによって、２組の映像表示システムにおいて入力操作から出力応答までの遅延時間をミリ秒オーダであわせることができる。 Here, a method for utilizing the delay time will be described. When the delay time of the first video display system is A milliseconds and the delay time of the second video display system is B milliseconds (A <B), the delay time of the first video display system is (A + N). For example, setting information input from the OSD included in the video display device 12 is written in the storage unit of the control calculation unit of the video display device 12 so as to be milliseconds (N = BA). The entire video display system operates based on the setting information. As a result, the delay time from the input operation to the output response can be adjusted in the order of milliseconds in the two sets of video display systems.
　なお、上述の説明では、映像表示システムの遅延時間を映像表示装置１２のＯＳＤにより設定する方法を説明した。しかし、この方法に限らない。映像表示システムの遅延時間は演算装置１１により調整されてもよい。 In the above description, the method for setting the delay time of the video display system by the OSD of the video display device 12 has been described. However, it is not limited to this method. The delay time of the video display system may be adjusted by the arithmetic unit 11.
　以上より、本実施形態における映像表示システムによれば、ユーザの入力操作から映像表示装置における映像変化が生じるまでの映像表示システム全体にわたって遅延時間を評価し、この評価結果を考慮した映像表示システムを構築することにより他の映像表示システムとの遅延時間の差を低減させることができる。また、演算装置あるいは映像表示装置において他のシステムを考慮して遅延時間を設定することにより他の映像表示システムとの遅延時間の差を低減させることができる。 As described above, according to the video display system in the present embodiment, the delay time is evaluated over the entire video display system from the user input operation until the video change occurs in the video display device, and the video display system in consideration of the evaluation result is provided. By constructing, the difference in delay time from other video display systems can be reduced. In addition, by setting the delay time in consideration of other systems in the arithmetic device or the video display device, the difference in delay time from other video display systems can be reduced.
