　以下、本発明の実施の形態を図面を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図１は、本発明の実施の形態に係る画像表示システム１０の概略構成を示す図である。画像表示システム１０は、動画コンテンツを再生する再生装置１と、再生装置１を遠隔操作するリモコン２と、再生装置２が再生した動画コンテンツを表示する表示装置３と、を備えている。画像表示システム１０は、早送りまたは早戻し時のコンテンツ表示（以下、早送りまたは早戻し表示という）に特徴を有している。すなわち、画像表示システム１０は、動画コンテンツを再生中に早送りまたは早戻しの指示がされると、表示装置３の再生画面下に、再生時点を中心とした複数のシーン（現在、過去及び未来のシーン）のサムネイル画像（縮小静止画像）を一覧表示するとともに、この複数のサムネイル画像を所定の更新間隔で更新表示して、早送りまたは早戻し表示を行うようになっている。そしてこのときの早送りまたは早戻し表示の速度（具体的には、隣接する各サムネイル画像間の時間間隔、及び各サムネイル画像の更新間隔。以下、隣接するサムネイル画像の間の時間間隔をＴ１、各サムネイル画像の更新間隔をＴ２と表記する）は、リモコン２に設けられた操作量検知デバイス２１（詳しくは後述する）の操作量に応じて、柔軟に調整されるようになっている。 FIG. 1 is a diagram showing a schematic configuration of an image display system 10 according to an embodiment of the present invention. The image display system 10 includes a playback device 1 that plays back moving image content, a remote controller 2 that remotely controls the playback device 1, and a display device 3 that displays the moving image content played back by the playback device 2. The image display system 10 is characterized by content display during fast forward or fast reverse (hereinafter referred to as fast forward or fast reverse display). That is, when an instruction for fast-forward or fast-reverse is given during playback of moving image content, the image display system 10 displays a plurality of scenes (current, past, and future) centered on the playback time point below the playback screen of the display device 3. In addition to displaying a list of thumbnail images (reduced still images) of scenes, the plurality of thumbnail images are updated and displayed at predetermined update intervals to perform fast forward or fast reverse display. The speed of fast-forward or fast-reverse display at this time (specifically, the time interval between adjacent thumbnail images and the update interval of each thumbnail image. Hereinafter, the time interval between adjacent thumbnail images is T1, The update interval of the thumbnail image is expressed as T2) is flexibly adjusted according to the operation amount of the operation amount detection device 21 (described later in detail) provided in the remote controller 2.
　図２（ａ）は、画像表示システム１０が早送りまたは早戻し表示をする場合の表示装置３の表示画面を示している。表示画面には、再生時点のシーンの静止画３１が表示されるとともに、表示画面下方に出現したサムネイル領域３２に、複数のサムネイル画像４１～４３、５１、６１～６３が表示される。なお、本実施の形態においては、表示画面の左右方向に沿って７つのサムネイル画像４１～４３、５１、６１～６３が表示される。 FIG. 2A shows a display screen of the display device 3 when the image display system 10 performs fast forward or fast reverse display. On the display screen, a still image 31 of the scene at the time of playback is displayed, and a plurality of thumbnail images 41 to 43, 51, and 61 to 63 are displayed in the thumbnail area 32 that appears at the bottom of the display screen. In the present embodiment, seven thumbnail images 41 to 43, 51, and 61 to 63 are displayed along the horizontal direction of the display screen.
　ここで、サムネイル画像５１は、再生時点のシーン（フレーム画像）のサムネイル画像（静止画３１と同一内容の静止画）であり、サムネイル領域３２の中央に他のサムネイル画像４１～４３及び６１～６３よりも大きな画像で表示される。サムネイル画像４１～４３は、再生時点よりも過去のシーン（フレーム画像）のサムネイル画像であり、サムネイル画像５１の左側に表示される。左に行くほど再生時点から遠ざかり、より過去のシーンとなる。一方、サムネイル画像６１～６３は、再生時点よりも未来のシーン（フレーム画像）のサムネイル画像であり、サムネイル画像５１の右側に表示される。右に行くほど再生時点から遠ざかり、より未来のシーンとなる。なお、本実施の形態においては、図２（ａ）に示すように、サムネイル画像４１～４３及びサムネイル画像６１～６３は、同一の大きさの画像で表示されるが、図２（ｂ）に示すように、早送り表示の場合は、サムネイル画像６１～６３をサムネイル画像４１～４３よりやや大きく表示し、図２（ｃ）に示すように、早戻り表示の場合は、サムネイル画像４１～４３をサムネイル画像６１～６３よりやや大きく表示するようにしてもよい。 Here, the thumbnail image 51 is a thumbnail image (still image having the same content as the still image 31) of the scene (frame image) at the time of reproduction, and the other thumbnail images 41 to 43 and 61 to 63 are located at the center of the thumbnail area 32. Is displayed in a larger image. The thumbnail images 41 to 43 are thumbnail images of scenes (frame images) that are past the playback time point, and are displayed on the left side of the thumbnail image 51. The further to the left, the farther away from the playback point, the more past the scene. On the other hand, the thumbnail images 61 to 63 are thumbnail images of scenes (frame images) that are future than the playback point, and are displayed on the right side of the thumbnail image 51. The further to the right, the farther away from the playback point, the more future scenes will be. In the present embodiment, as shown in FIG. 2A, the thumbnail images 41 to 43 and the thumbnail images 61 to 63 are displayed as images of the same size, but in FIG. As shown in FIG. 2, thumbnail images 61 to 63 are displayed slightly larger than thumbnail images 41 to 43 in the case of fast forward display, and thumbnail images 41 to 43 are displayed in the case of fast return display as shown in FIG. The thumbnail images 61 to 63 may be displayed slightly larger.
　このように、サムネイル領域３２の左右方向は、動画コンテンツの再生方向を示す時間軸となっており、左から右に向かうに従って、シーンは過去、現在そして未来と推移するようになっている。なお、本実施の形態においては、図２に示す複数のサムネイル画像４１～４３、５１、６１～６３における隣接するサムネイル画像の間の時間間隔Ｔ１は、いずれの間も同一であり（例えば、１秒など）、その値は、リモコン２から指示された早送りまたは早戻しの操作内容により決定される。 As described above, the left-right direction of the thumbnail area 32 is a time axis indicating the reproduction direction of the moving image content, and the scene changes from the past, the present, and the future from the left to the right. In the present embodiment, the time interval T1 between adjacent thumbnail images in the plurality of thumbnail images 41 to 43, 51, 61 to 63 shown in FIG. The value is determined by the fast-forward or fast-rewind operation content instructed from the remote controller 2.
　そして、このようなサムネイル画像４１～４３、５１、６１～６３の画像内容が所定の更新間隔Ｔ２（例えば、０．５秒など）で随時更新されていくので、サムネイル画像４１～４３、５１、６１～６３は早送りまたは早戻し表示されることとなる。詳しくは、早送り表示の場合には、更新間隔Ｔ２ごとに、再生時点を時間間隔Ｔ１だけ未来に進めて、進められた再生時点を中心に複数のサムネイル画像４１～４３、５１、６１～６３を作成し、作成したサムネイル画像４１～４３、５１、６１～６３を表示するようになっている。また、早戻し表示の場合には、更新間隔Ｔ２ごとに、再生時点を時間間隔Ｔ１だけ過去に戻して、戻された再生時点を中心に複数のサムネイル画像４１～４３、５１、６１～６３を作成し、作成したサムネイル画像４１～４３、５１、６１～６３を表示するようになっている。この結果、早送り表示の場合には、サムネイル領域３２に表示されるサムネイル画像４１～４３、５１、６１～６３が随時、再生時点よりも未来の画像に更新されていくことになる。また、早戻し表示の場合には、サムネイル領域３２に表示されるサムネイル画像４１～４３、５１、６１～６３が随時、再生時点よりも過去の画像に更新されていくことになる。なお、この更新間隔Ｔ２の値も、リモコン２から指示された早送りまたは早戻しの操作内容により決定される。 Then, the image contents of such thumbnail images 41 to 43, 51, 61 to 63 are updated as needed at a predetermined update interval T2 (for example, 0.5 seconds), so that the thumbnail images 41 to 43, 51, 61-63 are displayed as fast forward or fast reverse. Specifically, in the case of fast-forward display, at each update interval T2, the playback time point is advanced to the future by the time interval T1, and a plurality of thumbnail images 41 to 43, 51, 61 to 63 are displayed around the advanced playback time point. The created thumbnail images 41 to 43, 51, and 61 to 63 are displayed. In the case of fast-reverse display, the playback time point is returned to the past by the time interval T1 at each update interval T2, and a plurality of thumbnail images 41 to 43, 51, 61 to 63 are displayed around the returned playback time point. The created thumbnail images 41 to 43, 51, and 61 to 63 are displayed. As a result, in the case of fast-forward display, the thumbnail images 41 to 43, 51, 61 to 63 displayed in the thumbnail area 32 are updated to images that are later than the playback point at any time. Further, in the case of fast reverse display, the thumbnail images 41 to 43, 51, and 61 to 63 displayed in the thumbnail area 32 are updated to images that are earlier than the playback point at any time. The value of the update interval T2 is also determined by the fast forward or fast reverse operation content instructed from the remote controller 2.
　このように画像表示システム１０は、早送りまたは早戻し表示機能に特徴を有するので、以下、画像表示システム１０の早送りまたは早戻し表示機能について詳説する。 Since the image display system 10 has a feature in the fast-forward or fast-reverse display function as described above, the fast-forward or fast-reverse display function of the image display system 10 will be described in detail below.
　図３は、リモコン２及びリモコン２に設けられた操作量検知デバイス２１の外観を示す概要図である。リモコン２は、図３に示すように、その表面の略中央に操作量検知デバイス２１を備えている。なお、操作量検知デバイス２１の下方に記されている目盛り（例えば、０、１２７、－１２８など）は、操作量検知デバイス２１が検知した左右方向の移動量に対応するデジタル値を示しており、後述するデジタル化された移動量データの値である。 FIG. 3 is a schematic diagram showing the external appearance of the remote controller 2 and the operation amount detection device 21 provided in the remote controller 2. As shown in FIG. 3, the remote controller 2 includes an operation amount detection device 21 at the approximate center of the surface thereof. A scale (for example, 0, 127, -128, etc.) shown below the operation amount detection device 21 indicates a digital value corresponding to the horizontal movement amount detected by the operation amount detection device 21. These are the values of digitized movement amount data, which will be described later.
　操作量検知デバイス２１は、左右方向にスライド可能であるとともに、復帰位置（原点）Ｐに対して復帰力を有する操作部２０１を備えている。操作量検知デバイス２１は、操作部２０１の復帰位置Ｐからの移動量に応じたアナログ値を出力するデバイスであり、例えば、移動量を可変抵抗で検出する場合には、移動量を電圧値として出力する。 The operation amount detection device 21 includes an operation unit 201 that can slide in the left-right direction and has a return force with respect to the return position (origin) P. The operation amount detection device 21 is a device that outputs an analog value corresponding to the movement amount from the return position P of the operation unit 201. For example, when the movement amount is detected by a variable resistor, the movement amount is set as a voltage value. Output.
　リモコン２は、操作量検知デバイス２１の操作部２０１が復帰位置Ｐより右方向に操作された場合（正確には、操作部２０１の中心を、後述する移動量データの値が１０～１２７となる範囲に位置づけた場合）には早送り、スライド部２０１が復帰位置Ｐより左方向に操作された場合（正確には、操作部２０１の中心を、後述する移動量データの値が－１２８～－１０となる範囲に位置づけた場合）には早戻しを再生装置１に対して指示するようになっている。本実施の形態においては、操作部２０１の復帰位置Ｐからの移動量が大きいほど、早送りまたは早戻しの速度が速くなるように設定されている。 When the operation unit 201 of the operation amount detection device 21 is operated rightward from the return position P (to be exact, the remote control 2 has a movement amount data value of 10 to 127 at the center of the operation unit 201, which will be described later. When the slide unit 201 is operated in the left direction from the return position P (more precisely, the value of the movement amount data described later is −128 to −10). When the position is within the range, the playback device 1 is instructed to fast reverse. In the present embodiment, the fast-forward or fast-reverse speed is set to increase as the movement amount of the operation unit 201 from the return position P increases.
　また、リモコン２は、操作部２０１が復帰位置Ｐの近傍にある場合（操作部２０１の中心を、後述する移動量データの値が－９～９となる範囲に位置づけた場合）には、再生装置１に対して再生の指示を行うようになっている。なお、復帰位置Ｐから左右方向に移動した操作部２０１は、復帰位置Ｐへの復帰力を有しているので、操作部２０１に触れていた手を離すと、自動的に復帰位置Ｐに戻るようになっている。すなわち、操作部２０１から手を離した場合には、リモコン２は、再生装置１に対して再生の指示を行うようになっている。 In addition, the remote controller 2 reproduces when the operation unit 201 is in the vicinity of the return position P (when the center of the operation unit 201 is positioned in a range in which a movement amount data value described later becomes −9 to 9). The apparatus 1 is instructed to reproduce. Note that the operation unit 201 that has moved in the left-right direction from the return position P has a return force to the return position P, and therefore automatically returns to the return position P when the hand that touched the operation unit 201 is released. It is like that. That is, when the hand is released from the operation unit 201, the remote controller 2 instructs the playback device 1 to play back.
　このように本実施の形態においては、リモコン２に設けられた操作量検知デバイス２１の操作部２０１を左右方向にスライドさせることにより、早送りまたは早戻しの速度を調整できるので、表示装置３に表示されているサムネイル画像４１～４３、５１、６１～６３を見ながら、簡単に早送りまたは早戻しの速度を調整することができるようになっている。 As described above, in the present embodiment, the fast-forward or fast-reverse speed can be adjusted by sliding the operation unit 201 of the operation amount detection device 21 provided in the remote controller 2 in the left-right direction. While viewing the thumbnail images 41 to 43, 51 and 61 to 63, the fast-forward or fast-reverse speed can be easily adjusted.
　図４は、リモコン２及び再生装置１の機能構成図である。リモコン２は、図４に示すように、操作量検知デバイス２１、Ａ／Ｄ変換部２２、制御コードテーブル２３、制御コード判定部２４、及び制御コード送信部２５を備えている。 FIG. 4 is a functional configuration diagram of the remote controller 2 and the playback device 1. As shown in FIG. 4, the remote controller 2 includes an operation amount detection device 21, an A / D conversion unit 22, a control code table 23, a control code determination unit 24, and a control code transmission unit 25.
　操作量検知デバイス２１は、スライド部２０１の位置を検知し、検知した位置をアナログ値の位置データとしてＡ／Ｄ変換部２２に出力するようになっている。ここにいう位置データとは、その値が、スライド部２０１の操作方向（原点Ｐよりも左に操作したか、あるいは右に操作したか）及び操作量（原点Ｐからどれくらいの距離を操作したか）を示すデータである。 The operation amount detection device 21 detects the position of the slide unit 201 and outputs the detected position to the A / D conversion unit 22 as analog value position data. The position data here refers to the value of the operation direction of the slide unit 201 (whether it has been operated to the left or to the right of the origin P) and the operation amount (how far from the origin P it has been operated). ).
　Ａ／Ｄ変換部２２は、操作量検知デバイス２１から出力されたアナログ値の位置データをデジタル変換し、デジタル値の位置データを制御コード判定部２４に出力するようになっている。本実施の形態では、Ａ／Ｄ変換部２２として８ビットＡ／Ｄ変換器を用いているので、デジタル値として、－１２８～１２７の範囲の値を得ることができる（図３参照）。 The A / D conversion unit 22 digitally converts the analog position data output from the operation amount detection device 21 and outputs the digital position data to the control code determination unit 24. In the present embodiment, since an 8-bit A / D converter is used as the A / D converter 22, a value in the range of −128 to 127 can be obtained as a digital value (see FIG. 3).
　制御コードテーブル２３は、デジタル変換された位置データの値と制御コードを対応付けて記憶しているデータテーブルであり、デジタル変換された位置データの値を制御コードに変換する際に参照される。図５に本実施の形態で用いる制御コードテーブル２３を示す。 The control code table 23 is a data table that stores the digitally converted position data value and the control code in association with each other, and is referred to when the digitally converted position data value is converted into a control code. FIG. 5 shows a control code table 23 used in the present embodiment.
　図５に示す制御コードは、具体的には、早送り、早戻し、または再生を示すコードとなっており、ＦＦ１～ＦＦ１０は早送りを示す制御コード、ＰＬＡＹは再生を示す制御コード、ＲＥＷ１～１０は早戻しを示す制御コードである。このように本実施の形態の制御コードテーブル２３は、早送り及び早戻しの速度を１０段階に分けて管理しており、ＦＦまたはＲＥＷの後の数字が大きい制御コードほど、早送りまたは早戻しの速度が速くなることを示している。 Specifically, the control codes shown in FIG. 5 are codes indicating fast forward, fast reverse, or reproduction. FF1 to FF10 are control codes indicating fast forward, PLAY is a control code indicating reproduction, and REW1 to 10 are codes. This is a control code indicating fast rewind. As described above, the control code table 23 according to the present embodiment manages the fast-forward and fast-reverse speeds in 10 stages. The control code having a larger number after FF or REW has a fast-forward or fast-reverse speed. Shows that it will be faster.
　なお、本実施の形態では、－１２８～１２７の間を等間隔に分けて制御コードを割り当てるのではなく、早送りまたは早戻しの速度が低速になるほど割り当てられる位置データの範囲を広く取っている。例えば、ＦＦ１では１０～３１（数値範囲は２２）、ＦＦ３では５０～６５（数値範囲は１６）、ＦＦ６では９０～９８（数値範囲は９）、ＦＦ１０では１２０～１２７（数値範囲は８）である。これは、早送りまたは早戻しの操作を行う場合には、高速時よりも低速時の方が速度に対する正確性を求めることから、低速時における位置データの範囲を広くして低速時の操作性を向上させるようにしたものである。 In the present embodiment, the control code is not assigned by dividing the interval between −128 and 127 at equal intervals, but the range of the position data to be assigned becomes wider as the speed of fast forward or fast reverse becomes lower. For example, 10 to 31 (number range is 22) for FF1, 50 to 65 (number range is 16) for FF3, 90 to 98 (number range is 9) for FF6, 120 to 127 (number range is 8) for FF10. is there. This is because when fast-forwarding or fast-rewinding operation is performed, accuracy at speed is obtained at low speed rather than at high speed, so the range of position data at low speed is widened to improve operability at low speed. It is intended to improve.
　制御コード判定部２４は、Ａ／Ｄ変換部２２から出力された位置データ及び制御コードテーブル２３に基づいて、再生装置１に送信する制御コードを決定するようになっている。すなわち、制御コード判定部２４は、制御コードテーブル２３を参照して、Ａ／Ｄ変換部２２から出力された位置データの値に対応する制御コードを取得することにより、位置データの値を制御コードに変換するようになっている。例えば、Ａ／Ｄ変換部２２から出力された位置データの値が４０の場合には、制御コード判定部２３は、制御コード「ＦＦ２」を決定する。 The control code determination unit 24 determines a control code to be transmitted to the playback device 1 based on the position data output from the A / D conversion unit 22 and the control code table 23. That is, the control code determination unit 24 refers to the control code table 23 and acquires a control code corresponding to the value of the position data output from the A / D conversion unit 22, whereby the value of the position data is controlled by the control code. It is supposed to convert to. For example, when the value of the position data output from the A / D conversion unit 22 is 40, the control code determination unit 23 determines the control code “FF2”.
　なお、制御コードが早送りまたは早戻しを示す制御コードから再生を示す制御コードに変化した場合には、制御コード判定部２４は、予め定められた待ち時間（例えば、５００ｍ秒など）を待って、制御コードに変化がなければ（早送りまたは早戻しを示す制御コードに変化していなければ）、制御コードを、再生を示す制御コードに決定する。これは、ユーザの操作が早送りから早戻しに移行する場合、または早戻りから早送りに移行する場合には、操作の途中で原点Ｐを通過するので、このような場合には再生の指示を与えないようにするためである。 When the control code changes from a control code indicating fast-forward or fast-reverse to a control code indicating reproduction, the control code determination unit 24 waits for a predetermined waiting time (for example, 500 milliseconds), If there is no change in the control code (if the control code does not change to fast-forward or fast-reverse), the control code is determined to be a control code indicating reproduction. This is because when the user's operation shifts from fast-forward to fast-reverse or from fast-reverse to fast-forward, the origin P is passed in the middle of the operation. In such a case, a reproduction instruction is given. This is to prevent it from occurring.
　制御コード送信部２５は、制御コード判定部２４が決定した制御コードを、無線通信を介して再生装置１に送信するようになっている。本実施の形態においては、無線通信に赤外線通信を用いているが、他の通信方式、例えば、ＲＦ（Radio Frequency）通信を用いてもよい。 The control code transmission unit 25 transmits the control code determined by the control code determination unit 24 to the playback device 1 via wireless communication. In the present embodiment, infrared communication is used for wireless communication, but other communication methods, for example, RF (Radio Frequency) communication may be used.
　一方、再生装置１は、図４に示すように、制御コード受信部１１、制御内容テーブル１２、制御内容決定部１３、画像データ作成部１４、及び画像データ出力部１５を備えている。なお、再生装置１としては、例えば、具体的には、ＢＤ（Blu-ray Disc）プレーヤ、ＢＤレコーダ、ＤＶＤ（Digital Versatile Disc）プレーヤ、ＤＶＤレコーダ、ＨＤＤ（Hard Disk Drive）レコーダなどが想定される。 Meanwhile, as shown in FIG. 4, the playback device 1 includes a control code receiving unit 11, a control content table 12, a control content determining unit 13, an image data creating unit 14, and an image data output unit 15. As the playback device 1, for example, a BD (Blu-ray Disc) player, a BD recorder, a DVD (Digital Versatile Disc) player, a DVD recorder, an HDD (Hard Disk Drive) recorder, and the like are specifically assumed. .
　制御コード受信部１１は、リモコン２から送信された制御コードを受信し、受信した制御コードを制御内容決定部１３に出力するようになっている。 The control code receiving unit 11 receives the control code transmitted from the remote controller 2 and outputs the received control code to the control content determining unit 13.
　制御内容テーブル１２は、制御コードと表示装置３に表示されるサムネイル画像の制御内容を対応付けて記憶しているデータテーブルである。ここで、サムネイル画像の制御内容とは、早送りまたは早戻しの速度を示す値であり、具体的には、サムネイル領域３２に表示される複数のサムネイル画像４１～４３、５１、６１～６３において隣接する各サムネイル画像間の時間間隔Ｔ１、及びサムネイル画像サムネイル画像４１～４３、５１、６１～６３の更新間隔（リフレッシュレート）Ｔ２を示している。図６に本実施の形態で用いる制御内容テーブル１２を示す。 The control content table 12 is a data table that stores the control code and the control content of the thumbnail image displayed on the display device 3 in association with each other. Here, the control content of the thumbnail image is a value indicating the fast forward or fast reverse speed. Specifically, the thumbnail image is adjacent to each other in the plurality of thumbnail images 41 to 43, 51, and 61 to 63 displayed in the thumbnail area 32. The time interval T1 between the thumbnail images to be displayed and the update interval (refresh rate) T2 of the thumbnail image thumbnail images 41 to 43, 51, 61 to 63 are shown. FIG. 6 shows a control content table 12 used in the present embodiment.
　図６に示す制御内容テーブル１２は、低速時（ＦＦ１～ＦＦ５、ＲＥＷ１～ＲＥＷ５）においては、時間間隔Ｔ１を一定（１秒）とし、速度を速くするに従って、更新間隔Ｔ２を短くしている。すなわち、本実施の形態では、低速時（ＦＦ１～ＦＦ５、ＲＥＷ１～ＲＥＷ５）には、更新間隔Ｔ２を短くすることにより、各サムネイル画像４１～４３、５１、６１～６３のコマ送りの速度を上げている。一方、制御内容テーブル１２は、高速時（ＦＦ６～ＦＦ１０、ＲＥＷ６～ＲＥＷ１０）においては、速度が速くなるに従って、時間間隔Ｔ１を長くするとともに更新間隔Ｔ２を短くしている。すなわち、高速時（ＦＦ６～ＦＦ１０、ＲＥＷ６～ＲＥＷ１０）には、時間間隔Ｔ１を長くするともに更新間隔Ｔ２を短くすることにより、各サムネイル画像４１～４３、５１、６１～６３のコマ送りの速度を上げている。 In the control content table 12 shown in FIG. 6, at low speeds (FF1 to FF5, REW1 to REW5), the time interval T1 is constant (1 second), and the update interval T2 is shortened as the speed is increased. That is, in the present embodiment, at low speeds (FF1 to FF5, REW1 to REW5), the frame interval of each thumbnail image 41 to 43, 51, 61 to 63 is increased by shortening the update interval T2. ing. On the other hand, in the control content table 12, at high speeds (FF6 to FF10, REW6 to REW10), the time interval T1 is lengthened and the update interval T2 is shortened as the speed increases. That is, at high speed (FF6 to FF10, REW6 to REW10), the frame interval speed of each of the thumbnail images 41 to 43, 51, and 61 to 63 is increased by increasing the time interval T1 and shortening the update interval T2. Raised.
　制御内容決定部１３は、制御コード受信部１１から出力された制御コード、及び制御内容テーブル１２に基づいて、表示装置３に表示されるサムネイル画像４１～４３、５１、６１～６３の制御内容を決定するようになっている。すなわち、制御内容決定部１３は、制御内容テーブル１２を参照して、制御コード受信部１１から出力された制御コードに対応する制御内容を取得し、制御コードを制御内容に変換するようになっている。例えば、受信した制御コードの値が「ＦＦ３」の場合には、制御内容決定部１３は、時間間隔Ｔ１を１秒、更新間隔Ｔ２を０．２秒と決定する。 Based on the control code output from the control code receiving unit 11 and the control content table 12, the control content determination unit 13 displays the control content of the thumbnail images 41 to 43, 51, and 61 to 63 displayed on the display device 3. It comes to decide. That is, the control content determination unit 13 refers to the control content table 12, acquires the control content corresponding to the control code output from the control code reception unit 11, and converts the control code into the control content. Yes. For example, when the value of the received control code is “FF3”, the control content determination unit 13 determines the time interval T1 as 1 second and the update interval T2 as 0.2 seconds.
　画像データ作成部１４は、制御内容決定部１３で決定されたサムネイル画像の制御内容に従って、サムネイル画像４１～４３、５１、６１～６３を作成し、作成したサムネイル画像４１～４３、５１、６１～６３を含む画像データを画像データ出力部１５に出力するようになっている。より詳しくは、動画コンテンツを構成しているフレーム画像の中から、決定された時間間隔Ｔ１に従って、再生時点を中心とした現在、過去、及び未来の７つのフレーム画像を選択し、選択された７つのフレーム画像に対応するサムネイル画像をそれぞれ作成するようになっている。また、決定された更新間隔Ｔ２ごとに、再生時点を時間間隔Ｔ１だけ未来（早送りの場合）または過去（早戻しの場合）に移動するとともに、決定された時間間隔Ｔ１に従って、移動した再生時点を中心とした現在、過去、及び未来の７つのフレーム画像を選択し、選択された７つのフレーム画像に対応するサムネイル画像をそれぞれ作成するようになっている。また、再生時点における静止画３１を作成し、上述したサムネイル画像と合わせて、表示装置３に表示される表示画面の画像データを作成している。 The image data creation unit 14 creates thumbnail images 41 to 43, 51, 61 to 63 according to the control content of the thumbnail images determined by the control content determination unit 13, and the created thumbnail images 41 to 43, 51, 61 to 63 The image data including 63 is output to the image data output unit 15. More specifically, seven frame images of the present, the past, and the future centered on the reproduction time point are selected from the frame images constituting the moving image content according to the determined time interval T1, and the selected 7 Thumbnail images corresponding to two frame images are respectively created. In addition, for each determined update interval T2, the playback time point is moved to the future (in the case of fast forward) or the past (in the case of fast reverse) by the time interval T1, and the playback time point that has been moved in accordance with the determined time interval T1 is displayed. The center, present, past, and future seven frame images are selected, and thumbnail images corresponding to the selected seven frame images are respectively created. In addition, a still image 31 at the time of reproduction is created, and image data of a display screen displayed on the display device 3 is created together with the above-described thumbnail image.
　なお、本実施の形態においては、再生時点のフレーム画像が００フレームでない場合には（１秒の途中のフレーム画像が選択された場合には）、００フレームでないサムネイル４１～４３、５１、６１～６３が作成されるが、これとは別に、００フレームに対応するサムネイル画像４１～４３、５１、６１～６３が作成されるようにしてもよい。例えば、再生時点のフレーム画像が５分３１秒１５フレームの場合には、本実施の形態においては、５分３１秒１５フレームのサムネイル画像５１が作成されるが、５分３１秒００フレームのサムネイル画像５１が作成されるようにしてもよい。 In the present embodiment, when the frame image at the time of reproduction is not 00 frames (when a frame image in the middle of 1 second is selected), thumbnails 41 to 43, 51, 61 to 63 is created. Alternatively, thumbnail images 41 to 43, 51, 61 to 63 corresponding to 00 frames may be created. For example, if the frame image at the time of reproduction is 5 minutes 31 seconds 15 frames, in this embodiment, a thumbnail image 51 of 5 minutes 31 seconds 15 frames is created, but a thumbnail of 5 minutes 31 seconds 00 frames. The image 51 may be created.
　画像データ出力部１５は、画像データ作成部１４が作成したサムネイル画像４１～４３、５１、６１～６３を含む画像データを表示装置３に出力するようになっている。なお、表示装置３としては、例えば、具体的には、ＴＶ（Television）、モニターなどが想定される。また、本実施の形態においては、再生装置１と表示装置３は、物理的に別筐体の装置としたが、これに限定されず、双方の機能を備えた１つの装置としてもよい。 The image data output unit 15 outputs image data including thumbnail images 41 to 43, 51, 61 to 63 created by the image data creation unit 14 to the display device 3. As the display device 3, for example, specifically, a TV (Television), a monitor, or the like is assumed. In the present embodiment, the playback device 1 and the display device 3 are physically separate devices. However, the present invention is not limited to this, and may be a single device having both functions.
　図７は、制御コードが「ＦＦ３」の場合の表示装置３に表示される表示画面の変化の様子を示している。なお、表示装置３に表示される静止画３１は省略している。また、図７及び図８に示したサムネイル画像４１～４３、５１、６１～６３内の時刻は、サムネイル画像４１～４３、５１、６１～６３の画像内容を識別するために説明上付したものであり、実際には表示されない。例えば、「５：３０」と記されたサムネイル画像５１は、動画コンテンツのコンテンツ開始位置から５分３０秒後のフレーム画像に対するサムネイル画像であることを示している。以下、画像内に５：３０と記されたサムネイル画像は、５：３０のサムネイル画像と称して説明を行う。 FIG. 7 shows how the display screen displayed on the display device 3 changes when the control code is “FF3”. Note that the still image 31 displayed on the display device 3 is omitted. Further, the times in the thumbnail images 41 to 43, 51, 61 to 63 shown in FIGS. 7 and 8 are given for explanation in order to identify the image contents of the thumbnail images 41 to 43, 51, 61 to 63. It is not actually displayed. For example, the thumbnail image 51 marked “5:30” indicates that it is a thumbnail image for the frame image 5 minutes and 30 seconds after the content start position of the moving image content. Hereinafter, the thumbnail image described as 5:30 in the image will be referred to as a 5:30 thumbnail image.
　制御コードが「ＦＦ３」の場合には、時間間隔Ｔ１は１秒なので、例えば、再生時点が５分３０秒であるときには、５分３０秒のサムネイル画像５１、５分２７秒のサムネイル画像４１、５分２８秒のサムネイル画像４２、５分２９秒のサムネイル画像４３、５分３１秒のサムネイル画像６１、５分３２秒のサムネイル画像６２、及び５分３３秒のサムネイル画像６３が表示装置３のサムネイル領域３２に表示される。そして、制御コードが「ＦＦ３」の場合には、更新間隔Ｔ２は０．２秒なので、再生時点が５分３０秒であるときのサムネイル表示の開始から０．２秒が経過すると、再生時点が５分３１秒となり、５分３１秒のサムネイル画像５１、５分２８秒のサムネイル画像４１、５分２９秒のサムネイル画像４２、５分３０秒のサムネイル画像４３、５分３２秒のサムネイル画像６１、５分３３秒のサムネイル画像６２、５分３４秒のサムネイル画像６３が表示装置３のサムネイル領域３４に表示される。 When the control code is “FF3”, since the time interval T1 is 1 second, for example, when the reproduction time point is 5 minutes 30 seconds, the thumbnail image 51 of 5 minutes 30 seconds, the thumbnail image 41 of 5 minutes 27 seconds, A thumbnail image 42 of 5 minutes and 28 seconds, a thumbnail image 43 of 5 minutes and 29 seconds, a thumbnail image 61 of 5 minutes and 31 seconds, a thumbnail image 62 of 5 minutes and 32 seconds, and a thumbnail image 63 of 5 minutes and 33 seconds are displayed on the display device 3. It is displayed in the thumbnail area 32. When the control code is “FF3”, the update interval T2 is 0.2 seconds. Therefore, when 0.2 seconds have elapsed from the start of thumbnail display when the playback time is 5 minutes and 30 seconds, the playback time is 5 minutes 31 seconds thumbnail image 51, 5 minutes 28 seconds thumbnail image 41, 5 minutes 29 seconds thumbnail image 42, 5 minutes 30 seconds thumbnail image 43, 5 minutes 32 seconds thumbnail image 61 A thumbnail image 62 of 5 minutes 33 seconds and a thumbnail image 63 of 5 minutes 34 seconds are displayed in the thumbnail area 34 of the display device 3.
　このように、制御コードが「ＦＦ３」の場合には、０．２秒ごとに各サムネイル画像が１コマずつ左に移動していくことにより、早送り表示が行われる。 As described above, when the control code is “FF3”, each thumbnail image is moved to the left by one frame every 0.2 seconds, whereby fast-forward display is performed.
　図８は、制御コードが途中で「ＦＦ２」から「ＦＦ３」に変化する場合の表示装置３に表示されるサムネイル画像４１～４３、５１、６１～６３の変化の様子を示している。この場合には、時間間隔Ｔ１は１秒のまま変わらないが、更新間隔Ｔ２は０．３秒から０．２秒に変化するので、各サムネイル画像の１コマずつ左に移動していくコマ送りの速度が途中からさらに速くなって、早送り表示が行われる。 FIG. 8 shows how the thumbnail images 41 to 43, 51, and 61 to 63 displayed on the display device 3 change when the control code changes from “FF2” to “FF3” in the middle. In this case, the time interval T1 remains 1 second, but the update interval T2 changes from 0.3 seconds to 0.2 seconds, so that each thumbnail image moves to the left one frame at a time. The speed is further increased from the middle, and fast-forward display is performed.
　以上述べたように、本実施の形態の画像表示システム１０によれば、動画コンテンツの早送りまたは早戻し表示をする場合に、簡単に早送り及び早戻しの速度変更が可能であり、目的のシーンの検索が容易である。 As described above, according to the image display system 10 of the present embodiment, when fast-forward or fast-reverse display of moving image content is performed, the speed of fast-forward and fast-reverse can be easily changed, and the target scene can be changed. Easy to search.
　すなわち、本実施の形態の画像表示システム１０によれば、リモコン２は、左右方向にスライド操作可能な操作量検知デバイス２１を備えているので、ユーザは、表示装置３に表示された複数のサムネイル画像４１～４３、５１、６１～６３を見ながら、簡単に早送りまたは早戻しの速度を変えて目的のシーンを探すことができる。 That is, according to the image display system 10 of the present embodiment, since the remote controller 2 includes the operation amount detection device 21 that can be slid in the left-right direction, the user can display a plurality of thumbnails displayed on the display device 3. While looking at the images 41 to 43, 51, 61 to 63, the target scene can be searched by changing the speed of fast forward or fast reverse.
　例えば、ユーザが、高速に早送り表示されている複数のサムネイル画像４１～４３、５１、６１～６３を見て、目的のシーンが近づいてきたと感じたときは、操作量検知デバイス２１の操作部２０１を操作して、低速に早送り表示させるようにすれば、目的のシーンが行き過ぎることなく、簡単に目的のシーンを探し出すことができる。また、早送り表示させて、目的のシーンが行き過ぎてしまった場合でも、操作量検知デバイス２１の操作部２０１を早送り方向から早戻し方向に方向転換するというスライド操作だけで早戻し表示をすることができるので、早送り表示と早戻し表示の転換が容易である。 For example, when the user sees a plurality of thumbnail images 41 to 43, 51 and 61 to 63 displayed in fast forward at high speed and feels that the target scene is approaching, the operation unit 201 of the operation amount detection device 21 is used. By operating to display fast-forward at a low speed, the target scene can be easily found without excessively going. In addition, even if the target scene is overrun by displaying fast-forward, it is possible to display fast-return only by a slide operation of changing the operation unit 201 of the operation amount detection device 21 from the fast-forward direction to the fast-reverse direction. This makes it easy to switch between fast forward and fast reverse displays.
　また、本実施の形態の画像表示システム１０によれば、７つのサムネイル画像４１～４３、５１、６１～６３を表示するので、ユーザは、現在・過去・未来のシーンを時系列にして一覧に見ることができ、前後のシーンの流れから目的のシーンを探しやすいという効果がある。 Further, according to the image display system 10 of the present embodiment, since the seven thumbnail images 41 to 43, 51, 61 to 63 are displayed, the user can list the current / past / future scenes in time series. It can be seen and it is easy to find the target scene from the flow of the preceding and following scenes.
　以上、本発明の実施の形態について説明してきたが、本発明は、上述した実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲において、本発明の実施の形態に対して種々の変形や変更を施すことができ、そのような変形や変更を伴うものもまた、本発明の技術的範囲に含まれるものである。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made to the embodiments of the present invention without departing from the gist of the present invention. Such modifications and changes can be made, and those accompanying such modifications and changes are also included in the technical scope of the present invention.
　例えば、上記実施の形態においては、操作量検知デバイス２１を左右方向にスライドするスライド型の操作量検知デバイスとしたが、この構成に限定されず、操作量検知デバイスに対する操作方向及び操作量を検知することができるデバイスであれば、いずれの構成としてもよい。 For example, in the above embodiment, the operation amount detection device 21 is a slide-type operation amount detection device that slides in the left-right direction. However, the present invention is not limited to this configuration, and the operation direction and operation amount for the operation amount detection device are detected. Any device can be used as long as it can be used.
　例えば、図９（ａ）に示すようなシャトル型の操作量検知デバイス２１Ａとしてもよい。操作量検知デバイス２１Ａは、左右方向に回転可能な操作部２０１Ａを備えており、操作部２０１Ａの復帰位置（原点）Ｐ１からの回転方向により早戻しまたは早送りを選択し、復帰位置Ｐ１からの回転量により早戻しまたは早送りの速度を調整するものである。具体的には、操作部２０１Ａが復帰位置Ｐ１より右周りに回転した場合は早送り、復帰位置Ｐ１より左回りに回転した場合は早戻しが選択され、復帰位置Ｐ１からの回転量が大きくなるほど、早送りまたは早戻しの速度は速くなるように調整されている。 For example, a shuttle-type operation amount detection device 21A as shown in FIG. The operation amount detection device 21A includes an operation unit 201A that can be rotated in the left-right direction, and selects fast return or fast forward according to the rotation direction from the return position (origin) P1 of the operation unit 201A, and rotation from the return position P1. The speed of fast reverse or fast forward is adjusted according to the amount. Specifically, fast forward is selected when the operation unit 201A rotates clockwise from the return position P1, and fast reverse is selected when the operation unit 201A rotates counterclockwise from the return position P1, and as the amount of rotation from the return position P1 increases, The fast forward or fast reverse speed is adjusted to be faster.
　また、図９（ｂ）に示すようなシーソー型の操作量検知デバイス２１Ｂとしてもよい。操作量検知デバイス２１Ｂは、左右方向の一端及び他端が復帰位置Ｐ２を中心に上下方向に沈み込む操作部２０１Ｂを備えており、操作部２０１Ｂの沈み込む位置により、早戻しまたは早送りを選択し、沈み込む量により早戻しまたは早送りの速度を調整している。具体的には、操作部の右端部２０１ＢＲが沈み込む場合は早送り、左端部２０１ＢＬが沈み込む場合は早戻しが選択され、定常状態（再生状態でもあり、右端部２０１ＢＲ及び左端２０１ＢＬの双方が沈んでいない状態）からの沈み量が大きくなるほど、早送りまたは早戻しの速度は速くなるように調整されている。 Alternatively, a seesaw type operation amount detection device 21B as shown in FIG. 9B may be used. The operation amount detection device 21B includes an operation unit 201B in which one end and the other end in the left-right direction sink in the vertical direction centering on the return position P2, and selects fast reverse or fast forward depending on the position in which the operation unit 201B sinks. The speed of fast reverse or fast forward is adjusted according to the amount of sinking. Specifically, when the right end 201BR of the operation unit sinks, fast forward is selected, and when the left end 201BL sinks, fast reverse is selected, and the steady state (also in the playback state, both the right end 201BR and the left end 201BL sink). The speed of fast-forwarding or fast-rewinding is adjusted to increase as the amount of sinking from the (not-ready state) increases.
　また、図９（ｃ）に示すようなジョイスティック型の操作量検知デバイス２１Ｃとしてもよい。操作量検知デバイス２０１Ｃは、左右方向に倒し込み可能な操作部２０１Ｃを備えており、操作部２０１Ｃの定常状態（再生状態でもあり、操作部２０１が鉛直上方を向いている状態）からの倒し込み方向により早戻しまたは早送りを選択し、定常状態からの倒し込み角度により早戻しまたは早送りの速度を調整するものである。具体的には、操作部２０１Ｃが定常状態より右方向に倒し込まれた場合は早送り、操作部２０１Ｃが左方向に倒し込まれた場合は早戻しが選択され、定常状態からの倒し込み角度が大きくなるほど、早送りまたは早戻しの速度は速くなるように調整されている。 Also, a joystick type operation amount detection device 21C as shown in FIG. 9C may be used. The operation amount detection device 201C includes an operation unit 201C that can be tilted in the left-right direction. The operation amount detection device 201C is tilted from the steady state of the operation unit 201C (which is also a reproduction state and the operation unit 201 faces vertically upward). The fast reverse or fast forward is selected depending on the direction, and the fast reverse or fast forward speed is adjusted by the tilt angle from the steady state. Specifically, when the operation unit 201C is tilted to the right from the steady state, fast forward is selected, and when the operation unit 201C is tilted to the left, fast reverse is selected, and the tilt angle from the steady state is The faster the fast-forward or fast-reverse speed, the higher the speed.
　なお、上述した操作量検知デバイス２１Ａ、Ｂ及びＣは、いずれも復帰位置（定常状態）への復帰力を有しているので、手を離すと、復帰位置（定常状態）に戻るようになっている。 Note that the operation amount detection devices 21A, B, and C described above all have a return force to the return position (steady state), so that they return to the return position (steady state) when they are released. ing.
　また、操作量検知デバイスとしては、圧力を操作量として検知する圧力検知デバイスでもよい。この場合にも、圧力検知デバイスは、操作方向（早送りか早戻しの選択）及び操作量（圧力の大きさ）を検知可能な構成であり、例えば、図９（ｂ）に示すような構成を採用して、左右方向の一端または他端の選択が早送りまたは早戻しの選択に相当し、左右方向の一端及び他端が検知する圧力の大きさが早送りまたは早戻しの速度を決定するようにしてもよい。また、早送りまたは早戻しに対応するボタンをそれぞれ設け、それぞれのボタンが検知する圧力の大きさに応じて早送りまたは早戻しの速度を決定するようにしてもよい。 Also, the operation amount detection device may be a pressure detection device that detects pressure as an operation amount. Also in this case, the pressure detection device has a configuration capable of detecting the operation direction (selection of fast-forward or fast-reverse) and the operation amount (pressure magnitude), for example, a configuration as shown in FIG. The selection of one end or the other end in the left-right direction corresponds to the selection of fast-forward or fast-reverse, and the magnitude of the pressure detected by one end and the other end in the left-right direction determines the speed of fast-forward or fast-reverse. May be. Further, buttons corresponding to fast-forward or fast-reverse may be provided, and the fast-forward or fast-reverse speed may be determined according to the magnitude of pressure detected by each button.
　また、上記実施形態においては、図６に示す制御内容テーブル１２を用いて制御内容を決定したが、制御内容テーブル１２の制御内容はこれに限定されない。例えば、図１０に示すような制御内容テーブル１２Ａとしてもよいし、また、図１１に示すような制御内容テーブル１２Ｂとしてもよい。なお、図１０及び図１１に示す制御内容テーブル１２Ａ及び１２Ｂには、早送りのときの制御内容だけを記載している。 In the above embodiment, the control content is determined using the control content table 12 shown in FIG. 6, but the control content of the control content table 12 is not limited to this. For example, a control content table 12A as shown in FIG. 10 may be used, or a control content table 12B as shown in FIG. 11 may be used. Note that the control content tables 12A and 12B shown in FIGS. 10 and 11 describe only the control content at the time of fast-forwarding.
　図１０に示す制御内容テーブル１２Ａは、早送りの速度によらず時間間隔Ｔ１は一定（１秒）であり、速度が速くなるに従って、更新間隔Ｔ２は短くなっていく場合を示している。また、図１１に示す制御内容テーブル１２Ｂは、早送りの速度が速くなるに従って、概略、時間間隔Ｔ１は倍増して広がっていき、更新間隔Ｔ２が短くなっていく場合を示している。このように、制御内容テーブル１２の内容は種々設定が可能である。 The control content table 12A shown in FIG. 10 shows a case where the time interval T1 is constant (1 second) regardless of the fast-forwarding speed, and the update interval T2 becomes shorter as the speed increases. Further, the control content table 12B shown in FIG. 11 schematically shows a case where the time interval T1 doubles and widens and the update interval T2 becomes shorter as the fast-forward speed increases. In this way, the contents of the control content table 12 can be set in various ways.
　また、上記実施の形態においては、サムネイル領域３２に７つのサムネイル画像４１～４３、５１、６１～６３を表示し、その中心に再生時点のシーンのサムネイル画像５１を表示したが、再生時点のシーンのサムネイル画像５１の表示位置はこれに限定されない。 In the above embodiment, seven thumbnail images 41 to 43, 51, 61 to 63 are displayed in the thumbnail area 32, and the thumbnail image 51 of the scene at the playback time is displayed at the center. The display position of the thumbnail image 51 is not limited to this.
　例えば、図１２に示すように、早送り時には、再生時点のシーンのサムネイル画像５１をサムネイル領域３２の左端に配置し、サムネイル画像５１の右側に、この再生時点よりも未来のシーンのサムネイル画像６１～６６を配置するようにしてもよい。この場合には、未来のシーンのサムネイルが数多く（６つ）表示されることから、再生時点よりも未来のシーンに対する検索がさらに容易となる。同様にして、早戻り時には、再生時点のシーンのサムネイル画像５１をサムネイル領域３２の右端に配置し、サムネイル画像５１の左側に、この再生時点よりも過去のシーンのサムネイル画像４１～４６を配置するようにしてもよい。この場合には、過去のシーンのサムネイルが数多く（６つ）表示されることから、再生時点よりも過去のシーンに対する検索がさらに容易となる。 For example, as shown in FIG. 12, at the time of fast-forwarding, a thumbnail image 51 of a scene at the time of playback is arranged at the left end of the thumbnail area 32, and thumbnail images 61 to 61 of future scenes from the playback time are displayed on the right side of the thumbnail image 51. 66 may be arranged. In this case, since many (six) thumbnails of future scenes are displayed, it becomes easier to search for future scenes than at the time of playback. Similarly, at the time of fast return, the thumbnail image 51 of the scene at the time of playback is arranged at the right end of the thumbnail area 32, and the thumbnail images 41 to 46 of scenes before the playback time are arranged on the left side of the thumbnail image 51. You may do it. In this case, since many (six) thumbnails of past scenes are displayed, it becomes easier to search for past scenes than at the time of playback.
　また、図１３に示すように、早送りまたは早戻しの速度に応じて、再生時点のシーンのサムネイル画像５１の位置を変化させてもよい。すなわち、早送りの速度が速くなるに従って、再生時点のシーンのサムネイル画像５１をサムネイル領域３２の中心から左端に向かって徐々に移動して配置するようにしてもよい。例えば、制御コードがＦＦ１のときには、中心に配置されているサムネイル画像５１は、制御コードがＦＦ２～ＦＦ４のときには、左から３番目の位置に配置され、制御コードがＦＦ５～ＦＦ７のときには、左から２番目の位置に配置され、制御コードがＦＦ８～ＦＦ１０のときには、一番左の位置に配置される。同様にして、早戻しの速度が速くなるに従って、再生時点のシーンのサムネイル画像５１をサムネイル領域３２の中心から右端に向かって徐々に移動して配置するようにしてもよい。例えば、制御コードがＲＥＷ１のときには、中心に配置されているサムネイル画像５１は、制御コードがＲＥＷ２～ＲＥＷ４のときには、右から３番目の位置に配置され、制御コードがＲＥＷ５～ＲＥＷ７のときには、右から２番目の位置に配置され、制御コードがＲＥＷ８～ＲＥＷ１０のときには、一番右の位置に配置される。 As shown in FIG. 13, the position of the thumbnail image 51 of the scene at the time of playback may be changed according to the fast forward or fast reverse speed. That is, as the fast-forward speed increases, the thumbnail image 51 of the scene at the time of reproduction may be gradually moved from the center of the thumbnail area 32 toward the left end. For example, when the control code is FF1, the thumbnail image 51 arranged at the center is arranged at the third position from the left when the control code is FF2 to FF4, and from the left when the control code is FF5 to FF7. When the control code is FF8 to FF10, it is arranged at the leftmost position. Similarly, the thumbnail image 51 of the scene at the time of playback may be gradually moved from the center of the thumbnail area 32 toward the right end as the fast reverse speed increases. For example, when the control code is REW1, the thumbnail image 51 arranged at the center is arranged at the third position from the right when the control code is REW2 to REW4, and from the right when the control code is REW5 to REW7. When the control code is REW8 to REW10, it is arranged at the rightmost position.
　この場合、当然のことながら、サムネイル画像５１の配置位置の変化に伴って、未来または過去のシーンのサムネイル画像の数も変化する。すなわち、早送り表示の場合には、速度を上げるに従って、未来のシーンのサムネイル画像の数が増え、過去のシーンのサムネイル画像の数が減っていく。同様にして、早戻し表示の場合には、早戻し速度を上げるに従って、過去のシーンのサムネイル画像が増え、未来のシーンのサムネイル画像が減っていく。 In this case, as a matter of course, as the arrangement position of the thumbnail images 51 changes, the number of thumbnail images of future or past scenes also changes. That is, in the case of fast-forward display, as the speed is increased, the number of thumbnail images of future scenes increases and the number of thumbnail images of past scenes decreases. Similarly, in the case of fast reverse display, the thumbnail images of past scenes increase and the thumbnail images of future scenes decrease as the fast reverse speed is increased.
　なお、上記実施の形態の画像表示システム１０は、サムネイル領域３２に７つのサムネイル画像を表示したが、サムネイル領域３２に表示されるサムネイル画像の数はこれに限定されない。例えば、サムネイル領域３２に５つのサムネイル画像を表示するようにしてもよい。この場合には、再生時点のサムネイル画像に加えて、過去及び未来のサムネイル画像を２つずつ表示することになる。 Although the image display system 10 of the above embodiment displays seven thumbnail images in the thumbnail area 32, the number of thumbnail images displayed in the thumbnail area 32 is not limited to this. For example, five thumbnail images may be displayed in the thumbnail area 32. In this case, in addition to the thumbnail images at the time of reproduction, two past and future thumbnail images are displayed.
　なお、上記実施の形態の画像表示システム１０は、早送りまたは早戻し表示機能を動画コンテンツのシーン検索に適用したが、他の用途に適用してもよい。 In the image display system 10 of the above embodiment, the fast-forward or fast-reverse display function is applied to the scene search of the moving image content, but may be applied to other uses.
　例えば、画像表示システム１０の早送りまたは早戻し機能を動画コンテンツのチャプター検索に対して適用してもよい。図１４は、画像表示システム１０の早送りまたは早戻し表示機能を動画コンテンツのチャプター検索に適用した場合の表示装置３に表示される早送りまたは早戻し表示の画面である。 For example, the fast-forward or fast-reverse function of the image display system 10 may be applied to chapter search for moving image content. FIG. 14 is a fast-forward or fast-reverse display screen displayed on the display device 3 when the fast-forward or fast-reverse display function of the image display system 10 is applied to chapter search for moving image content.
　この場合は、表示画面には、再生時点のシーンの静止画３１が表示されるとともに、サムネイル領域３２には、複数のサムネイル画像４１～４３、５１、６１～６３が表示される。サムネイル画像５１は、再生時点のシーンのサムネイル画像（静止画３１と同一内容の静止画）である。サムネイル画像４１～４３は、それぞれ、再生時点よりも過去のチャプターの先頭フレーム画像のサムネイル画像であり、サムネイル画像５１の左側に表示される。左に行くほど再生時点から遠ざかり、より過去のシーンとなる。一方、サムネイル画像６１～６３は、再生時点よりも未来のチャプターの先頭フレーム画像のサムネイル画像であり、サムネイル画像５１の右に表示される。右に行くほど再生時点から遠ざかり、より未来のシーンとなる。 In this case, a still image 31 of the scene at the time of reproduction is displayed on the display screen, and a plurality of thumbnail images 41 to 43, 51, 61 to 63 are displayed in the thumbnail area 32. The thumbnail image 51 is a thumbnail image of the scene at the time of reproduction (a still image having the same content as the still image 31). Each of the thumbnail images 41 to 43 is a thumbnail image of the first frame image of the chapter before the playback time point, and is displayed on the left side of the thumbnail image 51. The further to the left, the farther away from the playback point, the more past the scene. On the other hand, the thumbnail images 61 to 63 are thumbnail images of the first frame image of the future chapter from the playback time point, and are displayed on the right side of the thumbnail image 51. The further to the right, the farther away from the playback point, the more future scenes will be.
　この場合には、操作量検知デバイス２１が検知した操作量により、隣接するサムネイル画像のチャプター間隔Ｔ１（チャプター）、及びサムネイル画像の更新間隔Ｔ２（秒）を決定する。ここで、チャプター間隔Ｔ１は、操作量検知デバイス２１が検知した操作量が大きくなるに従って、チャプター間隔Ｔ１を長くし、更新間隔Ｔ２を短くしていくのが好適である。例えば、一例としては、操作量検知デバイス２１が検知した操作量が小さい場合には、チャプター間隔Ｔ１を１として、すべてのチャプターのサムネイル画像を表示するようにし、操作量検知デバイス２１が検知した操作量が大きい場合には、チャプター間隔Ｔ１を３として、３チャプターごとにサムネイル画像を表示するようにしてもよい。図１４は、チャプター間隔Ｔ１が３の場合を示している。なお、図１４に示したサムネイル画像内のチャプター表示は、各サムネイル画像の画像内容を識別するために説明上付したものであり、実際には表示されない。 In this case, the chapter interval T1 (chapter) of adjacent thumbnail images and the update interval T2 (seconds) of thumbnail images are determined based on the operation amount detected by the operation amount detection device 21. Here, as for the chapter interval T1, it is preferable to lengthen the chapter interval T1 and shorten the update interval T2 as the operation amount detected by the operation amount detection device 21 increases. For example, when the operation amount detected by the operation amount detection device 21 is small, thumbnail images of all chapters are displayed with the chapter interval T1 set to 1, and the operation detected by the operation amount detection device 21 is detected. If the amount is large, the chapter interval T1 may be set to 3, and thumbnail images may be displayed every three chapters. FIG. 14 shows a case where the chapter interval T1 is 3. Note that the chapter display in the thumbnail image shown in FIG. 14 is provided for the purpose of identifying the image content of each thumbnail image, and is not actually displayed.
　このように、画像表示システム１０の早送りまたは早戻し機能を動画コンテンツのチャプター検索に対して適用した場合には、ユーザは操作量検知デバイス２１を操作することにより、チャプターの先頭シーンの流れる速度を柔軟に変更することができるので、目的のチャプターを探すことが容易となる。 As described above, when the fast-forward or fast-reverse function of the image display system 10 is applied to the chapter search of the moving image content, the user operates the operation amount detection device 21 to change the flow speed of the first scene of the chapter. Since it can be changed flexibly, it becomes easy to find a target chapter.
　また、画像表示システム１０の早送りまたは早戻し表示機能をスライドショーに対して適用してもよい。図１５は、画像表示システム１０の早送りまたは早戻し表示機能を写真画像のスライドショーに適用した場合の表示装置３に表示される早送りまたは早戻し表示の画面である。このように複数の写真画像を予め定められた順番で表示するスライドショーにおいて、早送りまたは早戻し表示をする場合には、図１５に示すように、表示画面には、現在再生されている写真画像３１が表示されるとともに、サムネイル領域３２には、複数のサムネイル画像４１～４３、５１、６１～６３が表示される。サムネイル画像５１は、現在再生されている写真画像３１のサムネイル画像である。サムネイル画像４１～４３は、すでに表示された写真画像のサムネイル画像であり、サムネイル画像５１の左に表示される。左に行くほど現在再生されている写真画像３１の順番よりも前の順番の写真画像となる。一方、サムネイル画像６１～６３は、これから表示する写真画像のサムネイル画像であり、サムネイル画像５１の右に表示される。右に行くほど現在再生されている写真画像３１の順番よりも後の順番の写真画像となる。 Further, the fast forward or fast reverse display function of the image display system 10 may be applied to the slide show. FIG. 15 is a fast-forward or fast-reverse display screen displayed on the display device 3 when the fast-forward or fast-reverse display function of the image display system 10 is applied to a photographic image slide show. In the slide show in which a plurality of photographic images are displayed in a predetermined order as described above, when fast-forward or fast-reverse display is performed, the currently reproduced photographic image 31 is displayed on the display screen as shown in FIG. And a plurality of thumbnail images 41 to 43, 51, 61 to 63 are displayed in the thumbnail area 32. The thumbnail image 51 is a thumbnail image of the photographic image 31 currently being reproduced. The thumbnail images 41 to 43 are thumbnail images of photographic images that have already been displayed, and are displayed on the left side of the thumbnail image 51. The further to the left is the photographic image in the order before the photographic image 31 currently being reproduced. On the other hand, the thumbnail images 61 to 63 are thumbnail images of photographic images to be displayed from now on, and are displayed to the right of the thumbnail image 51. The further to the right, the photographic images are in the order later than the order of the photographic images 31 currently being reproduced.
　この場合には、操作量検知デバイス２１が検知した操作量により、隣接するサムネイル画像の枚数間隔Ｔ１（枚数）、及びサムネイル画像の更新間隔Ｔ２（秒）を決定するようになっている。ここで、枚数間隔Ｔ１は、操作量検知デバイス２１が検知した操作量が大きくなるに従って、枚数間隔Ｔ１を長くし、更新間隔Ｔ２を短くしていくのが好適である。例えば、一例としては、操作量検知デバイス２１が検知した操作量が小さい場合には、枚数間隔Ｔ１を１として、間引きせずすべての写真画像のサムネイル画像を表示するようにし、操作量検知デバイス２１が検知した操作量が大きい場合には、枚数間隔Ｔ１を３として、２枚間引いて、３枚ごとにサムネイル画像を表示するようにしてもよい。 In this case, the number of adjacent thumbnail images T1 (number) and the thumbnail image update interval T2 (seconds) are determined based on the amount of operation detected by the operation amount detection device 21. Here, as for the sheet number interval T1, it is preferable to lengthen the sheet number interval T1 and shorten the update interval T2 as the operation amount detected by the operation amount detection device 21 increases. For example, when the operation amount detected by the operation amount detection device 21 is small, the number-of-photographs interval T1 is set to 1, and thumbnail images of all the photographic images are displayed without being thinned out. If the detected operation amount is large, the number interval T1 may be set to 3, and two images may be thinned out to display thumbnail images for every three images.
　このように、画像表示システム１０の早送りまたは早戻し機能をスライドショーに対して適用した場合には、ユーザは操作量検知デバイス２１を操作することにより、写真画像の流れる速度を柔軟に変更することができるので、目的の写真画像を探すことが容易となる。 As described above, when the fast forward or fast reverse function of the image display system 10 is applied to the slide show, the user can flexibly change the flow speed of the photographic image by operating the operation amount detection device 21. This makes it easy to search for the desired photographic image.
　また、画像表示システム１０の早送りまたは早戻し機能を音楽再生装置のジャケット検索に対して適用してもよい。図１６は、画像表示システム１０の早送りまたは早戻し表示機能を音楽再生装置のジャケット検索に適用した場合の表示装置３に表示される早送りまたは早戻し表示の画面である。このように複数のジャケット写真画像を予め定められた順番（例えば、アーティストの名前順やアルバムのタイトル順など）で表示して所望の音楽を検索するＣＤジャケット検索において、早送りまたは早戻し表示をする場合には、図１６に示すように、表示画面上に現在再生中の音楽のジャケット写真画像３１を表示するとともに、サムネイル領域３２には、複数のサムネイル画像４１～４３、５１、６１～６３が表示される。サムネイル画像５１は、現在再生されている音楽のジャケット写真画像３１のサムネイル画像である。サムネイル画像４１～４３は、現在再生中の音楽のジャケット写真画像３１よりも順番が前のジャケット写真画像のサムネイル画像であり、サムネイル画像５１の左に表示される。左に行くほど現在再生中の音楽のジャケット写真画像３１の順番よりも前の順番の写真画像となる。一方、サムネイル画像６１～６３は、現在再生中の音楽のジャケット写真画像３１よりも順番が後のジャケット写真画像のサムネイル画像であり、サムネイル画像５１の右に表示される。右に行くほど現在再生中の音楽のジャケット写真画像３１の順番よりも後の順番のジャケット写真画像となる。 Further, the fast forward or fast reverse function of the image display system 10 may be applied to the jacket search of the music playback device. FIG. 16 is a fast-forward or fast-reverse display screen displayed on the display device 3 when the fast-forward or fast-reverse display function of the image display system 10 is applied to the jacket search of the music playback device. In this way, in the CD jacket search for displaying a desired music by displaying a plurality of jacket photo images in a predetermined order (for example, artist name order, album title order, etc.), fast forward or fast reverse display is performed. In this case, as shown in FIG. 16, a jacket photo image 31 of the music currently being played is displayed on the display screen, and a plurality of thumbnail images 41 to 43, 51, 61 to 63 are displayed in the thumbnail area 32. Is displayed. The thumbnail image 51 is a thumbnail image of the jacket photo image 31 of the music currently being played. Thumbnail images 41 to 43 are thumbnail images of the jacket photo image in the order before the jacket photo image 31 of the music currently being played back, and are displayed on the left of the thumbnail image 51. The further to the left, the photographic images in the order before the order of the jacket photo images 31 of the music currently being played back. On the other hand, the thumbnail images 61 to 63 are the thumbnail images of the jacket photo images that are later in order than the jacket photo image 31 of the music currently being played back, and are displayed to the right of the thumbnail image 51. As it goes to the right, the jacket photo image is later in sequence than the order of the jacket photo image 31 of the currently playing music.
　この場合には、操作量検知デバイス２１が検知した操作量により、隣接するサムネイル画像の枚数間隔Ｔ１（枚数）、及びサムネイル画像の更新間隔Ｔ２（秒）を決定するようになっている。ここで、枚数間隔Ｔ１は、操作量検知デバイス２１が検知した操作量が大きくなるに従って、枚数間隔Ｔ１を長くし、更新間隔Ｔ２を短くしていくのが好適である。例えば、一例としては、操作量検知デバイス２１が検知した操作量が小さい場合には、枚数間隔Ｔ１を１として、間引きせずすべてのジャケット写真画像のサムネイル画像を表示するようにし、操作量検知デバイス２１が検知した操作量が大きい場合には、枚数間隔Ｔ１を３として、２枚間引いて、３枚ごとにジャケット写真画像のサムネイル画像を表示するようにしてもよい。また、操作量検知デバイス２１が検知した操作量が最大の場合には、各アルファベットの先頭のジャケット写真画像のサムネイル画像を表示するようにしてもよい。 In this case, the number of adjacent thumbnail images T1 (number) and the thumbnail image update interval T2 (seconds) are determined based on the amount of operation detected by the operation amount detection device 21. Here, as for the sheet number interval T1, it is preferable to lengthen the sheet number interval T1 and shorten the update interval T2 as the operation amount detected by the operation amount detection device 21 increases. For example, when the operation amount detected by the operation amount detection device 21 is small, the number interval T1 is set to 1, and thumbnail images of all jacket photo images are displayed without being thinned, and the operation amount detection device If the operation amount detected by 21 is large, the number interval T1 may be set to 3, and two thumbnails may be thinned to display thumbnail images of jacket photo images for every three. When the operation amount detected by the operation amount detection device 21 is the maximum, a thumbnail image of the jacket photo image at the head of each alphabet may be displayed.
　このように、画像表示システム１０の早送りまたは早戻し機能を音楽再生装置のジャケット検索に対して適用した場合には、ユーザは操作量検知デバイス２１を操作することにより、ジャケット写真画像の流れる速度を柔軟に変更することができるので、目的のジャケット写真画像を探すことが容易となる。 As described above, when the fast-forward or fast-reverse function of the image display system 10 is applied to the jacket search of the music playback device, the user operates the operation amount detection device 21 to control the speed at which the jacket photo image flows. Since it can be changed flexibly, it is easy to search for a target jacket photo image.
　なお、図１６においては、検索対象の画像が静止画（ジャケット写真画像）であったが、動画としてもよい。すなわち、複数の動画を所定の順番で表示して所望の動画コンテンツを検索する動画検索に画像表示システム１０の早送りまたは早戻し表示機能を適用してもよい。 In FIG. 16, the search target image is a still image (jacket photo image), but may be a moving image. That is, the fast-forward or fast-reverse display function of the image display system 10 may be applied to a video search for displaying a plurality of videos in a predetermined order to search for desired video content.
