Description

リスト処理装置及びリスト処理方法List processing apparatus and list processing method
　本発明は、ユーザによるリストの選択動作に対するリスト表示の更新反応速度の向上を目的とする。 An object of the present invention is to improve the update response speed of a list display in response to a list selection operation by a user.
　複数の処理項目を順番に並べたリストを表示画面に表示しておき、ユーザがリストの送り戻し操作を行うことによりリスト内のある項目を選択すると、選択された処理項目を実行するという、処理装置がある。ユーザがリストの送り戻し操作を行う度に、選択された処理項目（以下、選択項目という。）が遷移する。ユーザが連続して送り戻し操作を行うと、選択項目が次々に遷移する。この場合、送り戻し操作の度に選択項目に対応した処理を行うと、当該処理の実行によりＣＰＵリソースが占有され、送り戻し操作に応じたリストの表示更新処理が遅延してしまうという問題があった。 A process in which a list in which a plurality of process items are arranged in order is displayed on the display screen, and when a user selects an item in the list by performing a list return operation, the selected process item is executed. There is a device. Each time the user performs a list return operation, the selected processing item (hereinafter referred to as a selection item) changes. When the user continuously performs a return operation, the selection items transition one after another. In this case, if a process corresponding to the selection item is performed every time a return operation is performed, the CPU resource is occupied by the execution of the process, and the list display update process corresponding to the return operation is delayed. It was.
　特許文献１には、予め各々の項目毎に命令指示有効時間を設定登録しておき、タイマーによってカウントされる命令指示時間が命令指示有効時間を超えた場合にのみ命令を有効として実行するという、タイマー監視方法が開示されている。このタイマー監視方法によれば、項目が指定された瞬間に、対応する命令が実行されるわけではないので、命令の実行によりＣＰＵリソースが占有されることを抑制できる。 In Patent Literature 1, an instruction instruction valid time is set and registered for each item in advance, and the instruction is executed as valid only when the instruction instruction time counted by the timer exceeds the instruction instruction valid time. A timer monitoring method is disclosed. According to this timer monitoring method, since the corresponding instruction is not executed at the moment when the item is specified, it is possible to prevent the CPU resource from being occupied by the execution of the instruction.
　特許文献２には、タイマーによってカーソルを止めてから所定時間経過したかどうかを判定し、所定時間経過後、選択された操作項目を実行する方法が開示されている。 Patent Document 2 discloses a method of determining whether or not a predetermined time has elapsed since the cursor was stopped by a timer, and executing a selected operation item after the predetermined time has elapsed.
特開平８－１７１４７５号公報JP-A-8-171475 特開２００６－２５６５９９号公報JP 2006-256599 A
　しかし、特許文献１のタイマー監視方法は、画面上のマウス又はカーソルが項目上に移動した後で監視タイマーを開始し、その項目が選択され続けているかどうか、又はキー入力が続けられているかどうかにより、命令の有効又は無効を判断するため、上記のようなリストの送り戻し操作が連続して行われる場合に対応するものではない。 However, the timer monitoring method of Patent Document 1 starts a monitoring timer after the mouse or cursor on the screen moves over an item, and whether or not the item continues to be selected or whether or not key input is continued. Therefore, in order to determine whether the instruction is valid or invalid, this does not correspond to the case where the list return operation as described above is continuously performed.
　また、特許文献２のタイマー監視方法の場合、選択操作完了後、必ず所定時間をカウントし、そのカウントが経過してから選択された項目を実行する方法であるため、連続した送り戻し操作ではない場合も選択項目実行開始までに所定時間がかかってしまう問題があった。 In addition, in the timer monitoring method of Patent Document 2, since a predetermined time is always counted after the selection operation is completed, and the selected item is executed after the count has elapsed, it is not a continuous sending back operation. Even in this case, there is a problem that it takes a predetermined time to start executing the selected item.
　本発明は上述の問題に鑑み、リストの連続的な送り戻し操作に対してリスト更新処理の遅延を抑制するリスト処理装置及びリスト処理方法の提供を目的とする。 The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a list processing apparatus and a list processing method that suppress a delay in list update processing with respect to continuous list return operations.

When the operation is accepted and the first send-back operation is accepted, the execution of the processing item selected by the first send-back operation is instructed, and within a predetermined determination period from the acceptance of the first send-back operation.

　＜Ａ．実施の形態１＞
　＜Ａ－１．構成＞
　図１は、本発明の実施の形態１に係るリスト処理装置１１を含む、車載の表示システム１００の全体構成図である。以下、本発明のリスト処理装置を車載の表示システムに適用されるものとして説明を行う。 <A. Embodiment 1>
<A-1. Configuration>
FIG. 1 is an overall configuration diagram of an in-vehicle display system 100 including a list processing device 11 according to Embodiment 1 of the present invention. Hereinafter, the list processing apparatus of the present invention will be described as applied to an in-vehicle display system.
　表示システム１００は、ヘッドユニット１、センターディスプレイ２、ＩＣ（Instrument Cluster）デバイス３、ＩＣディスプレイ用操作デバイス４、センターディスプレイ用操作デバイス５及びスピーカ６を備えている。ヘッドユニット１は、リスト処理装置１１、ラジオチューナ１２、ＣＤ（Compact Disc）ドライブ１３、ＵＳＢ（Universal Serial Bus）１４を備えている。なお、ラジオチューナ１２、ＣＤドライブ１３、ＵＳＢ１４は、リスト処理装置１１が処理項目のリストを作成する対象となる外部デバイスの一例であり、ＤＶＤ（Digital Versatile Disc）ドライブやＢＤ（Blu-ray Disc）（Blu-ray：登録商標）ドライブなどを外部デバイスとしても良い。 The display system 100 includes a head unit 1, a center display 2, an IC (Instrument Cluster) device 3, an IC display operation device 4, a center display operation device 5, and a speaker 6. The head unit 1 includes a list processing device 11, a radio tuner 12, a CD (Compact Disc) drive 13, and a USB (Universal Serial Bus) 14. The radio tuner 12, the CD drive 13, and the USB 14 are examples of external devices for which the list processing device 11 creates a list of processing items, such as a DVD (Digital Versatile Disc) drive or a BD (Blu-ray Disc). A (Blu-ray: registered trademark) drive may be used as an external device.
　ＩＣデバイス３は、車速計、燃料計など運転者に必要な情報を表示するためのデバイスであり、ＣＡＮ（Controller Area Network）によりヘッドユニット１と接続されている。また、センターディスプレイ２はＨＤＭＩ（登録商標）等の通信インタフェースによりヘッドユニット１と接続されている。 The IC device 3 is a device for displaying information necessary for the driver, such as a vehicle speed meter and a fuel meter, and is connected to the head unit 1 by a CAN (Controller Area Network). The center display 2 is connected to the head unit 1 through a communication interface such as HDMI (registered trademark).
　ＩＣディスプレイ用操作デバイス４は、例えば車両のハンドルに取り付けられたハンドルリモコンとして実現する。ＩＣディスプレイ用操作デバイス４は、センターディスプレイ２の画面とは独立して、ＩＣディスプレイ３１に表示されたリストの送り戻し操作を行うことができる。大抵の場合、ハンドルリモコンは運転者がハンドルを把持した状態で運転しながら簡単な操作が行えるように少数のボタンから構成されており、図１の例では上下カーソルキーにより構成される。 The IC display operation device 4 is realized as a handle remote controller attached to the handle of a vehicle, for example. The IC display operation device 4 can perform a return operation of the list displayed on the IC display 31 independently of the screen of the center display 2. In most cases, the handle remote control is composed of a small number of buttons so that the driver can perform a simple operation while driving while holding the handle. In the example of FIG.
　センターディスプレイ用操作デバイス５は、例えばヘッドユニット１の筐体に取り付けられたボタン類や、当該筺体とは別体のリモコンとして構成される。センターディスプレイ用操作デバイス５は、ＩＣディスプレイ用操作デバイス４とは異なり、十字カーソルキーの他にＥＮＴＥＲキーとＢＡＣＫキーを備えている。ユーザは、例えば十字カーソルキーを用いてリストの送り戻し操作を行って任意の処理項目を指定した上で、ＥＮＴＥＲキーを押すことにより当該処理項目を選択する。すなわち、リストの送り戻し操作を行うだけでは処理項目の選択は行われない。これに対して、ＩＣディスプレイ用操作デバイス４は上下カーソルキーのみを備えており、カーソルキーを用いたリストの送り戻し操作により任意の処理項目を指定すると、それがすなわち処理項目の選択操作となる。 The center display operation device 5 is configured, for example, as buttons attached to the casing of the head unit 1 or as a remote controller separate from the casing. Unlike the IC display operation device 4, the center display operation device 5 includes an ENTER key and a BACK key in addition to the cross cursor key. For example, the user performs a list return operation using the cross cursor key to specify an arbitrary processing item, and then selects the processing item by pressing the ENTER key. That is, selection of a processing item is not performed only by performing a list return operation. On the other hand, the IC display operation device 4 has only the up and down cursor keys. When an arbitrary processing item is designated by a list return operation using the cursor keys, that is, a processing item selection operation is performed. .
　リスト処理装置１１は、表示データ作成部１１１、操作受付部１１２及び処理実行指示部１１３を備えている。ここで、操作受付部１１２は通信インタフェース、表示データ作成部１１１はＲＡＭ（Random Access Memory）等のメモリに格納されたプログラムを実行するＣＰＵ（Central Processing Unit）又はＧＰＵ（Graphic Processer Unit）、処理実行指示部１１３はＲＡＭ等のメモリに格納されたプログラムを実行するＣＰＵとして構成される。 The list processing device 11 includes a display data creation unit 111, an operation reception unit 112, and a process execution instruction unit 113. Here, the operation reception unit 112 is a communication interface, the display data creation unit 111 is a CPU (Central Processing Unit) or a GPU (Graphic Processing Unit) that executes a program stored in a memory such as a RAM (Random Access Memory), and a process is executed. The instruction unit 113 is configured as a CPU that executes a program stored in a memory such as a RAM.
　表示データ作成部１１１は、センターディスプレイ２でリスト表示をするための表示データと、ＩＣディスプレイ３１でリスト表示を行うための表示データの両方を作成している。ここで、表示データとは、上述した表示デバイスであるセンターディスプレイ２又はＩＣディスプレイ３１がＧＰＵを備えている場合は、表示デバイスが描画データを作成するために必要なデータであり、表示デバイスがＧＰＵを備えていない場合は、表示画面を描画するための描画データである。また、以下の説明では、センターディスプレイ２はＧＰＵを備えておらず、ＩＣディスプレイ３１はＧＰＵを備えているものとするが、いずれであっても良い。また、リスト処理装置１１、センターディスプレイ２及びＩＣディスプレイ３１によりリスト表示装置が構成される。 The display data creation unit 111 creates both display data for displaying a list on the center display 2 and display data for displaying a list on the IC display 31. Here, when the center display 2 or the IC display 31 which is the display device described above includes a GPU, the display data is data necessary for the display device to create drawing data. If it is not provided, it is drawing data for drawing the display screen. In the following description, the center display 2 is not provided with a GPU and the IC display 31 is provided with a GPU. The list display device 11, the center display 2 and the IC display 31 constitute a list display device.
　操作受付部１１２は、ＩＣディスプレイ用操作デバイス４又はセンターディスプレイ用操作デバイス５によるリストの送り戻し操作に関する操作情報を取得する、すなわち操作を受け付ける。そして、当該操作情報を表示データ作成部１１１及び処理実行指示部１１３に出力する。 The operation reception unit 112 acquires operation information related to a list return operation by the IC display operation device 4 or the center display operation device 5, that is, receives an operation. Then, the operation information is output to the display data creation unit 111 and the process execution instruction unit 113.
　処理実行指示部１１３は、操作情報を操作受付部１１２から受け、リスト中のいずれの処理項目が選択されているかを判断する。例えば、リストの各処理項目に整列番号を付しておき、選択中の処理項目の整列番号が３である場合にリスト送り操作が１回行われると、整列番号が４の処理項目を選択中の処理項目とする。そして、選択中の処理項目の実行を、外部デバイス（ラジオチューナ１２、ＣＤドライブ１３等）に指示する。例えばリストが放送局の選局リストである場合は、選択中の処理項目の放送局を選局するように、ラジオチューナ１２に指示する。 The process execution instruction unit 113 receives the operation information from the operation reception unit 112 and determines which process item in the list is selected. For example, if an alignment number is assigned to each processing item in the list, and the list sending operation is performed once when the alignment number of the selected processing item is 3, the processing item with the alignment number 4 is being selected. The processing item. Then, the external device (radio tuner 12, CD drive 13, etc.) is instructed to execute the selected processing item. For example, if the list is a broadcasting station tuning list, the radio tuner 12 is instructed to select a broadcasting station of the processing item being selected.
　表示データ作成部１１１は、リストの送り戻し操作が行われる度に、ＩＣディスプレイ３１用の表示データの更新を行う。一方、センターディスプレイ２用の表示データについては、処理実行指示部１１３が処理実行を指示するタイミングで更新を行う。 The display data creation unit 111 updates the display data for the IC display 31 every time a list return operation is performed. On the other hand, the display data for the center display 2 is updated at the timing when the process execution instructing unit 113 instructs to execute the process.
　＜Ａ－２．リスト送り戻し操作＞
　ここで、ＩＣディスプレイ用操作デバイス４を用いたリストの送り戻し操作と、それに伴うＩＣディスプレイ３１の表示の遷移を、図２を用いて説明する。図２には、ＩＣディスプレイ３１にラジオ局の選局リストを表示する場合の例を示している。リストの処理項目「１．bigFM WB」が選択されている状態で、ユーザがＩＣディスプレイ用操作デバイス４の下向き矢印を一回押すと（これを「リスト送り操作」とする）、当該リスト送り操作の操作情報がＩＣディスプレイ用操作デバイス４からＩＣデバイス３を介して操作受付部１１２に入力される。操作受付部１１２は当該操作情報を表示データ作成部１１１及び処理実行指示部１１３に出力する。表示データ作成部１１１は、リストの選択項目を次の項目に遷移して表示データを更新する。これにより、先ほどはリストの中で処理項目「１．bigFM WB」が選択項目としてアクティブに表示されていたが、今は処理項目「２．90.0MHz」が選択項目としてアクティブに表示される。また、処理実行指示部１１３では、処理項目「２．90.0MHz」の処理、すなわち「90.0MHz」の放送局への選局をラジオチューナ１２に指示する。 <A-2. List return operation>
Here, the list sending back operation using the IC display operation device 4 and the accompanying display transition of the IC display 31 will be described with reference to FIG. FIG. 2 shows an example in which a tuning list of radio stations is displayed on the IC display 31. When the processing item “1. bigFM WB” of the list is selected, when the user presses the downward arrow once for the IC display operation device 4 (this is referred to as “list feed operation”), the list feed operation is performed. Is input from the IC display operation device 4 to the operation reception unit 112 via the IC device 3. The operation reception unit 112 outputs the operation information to the display data creation unit 111 and the process execution instruction unit 113. The display data creation unit 111 updates the display data by changing the selection item of the list to the next item. As a result, the processing item “1. bigFM WB” was actively displayed as a selection item in the list earlier, but now the processing item “2.90.0 MHz” is actively displayed as a selection item. Further, the process execution instructing unit 113 instructs the radio tuner 12 to process the process item “2.90.0 MHz”, that is, to select a broadcast station of “90.0 MHz”.
　次に、ユーザがＩＣディスプレイ用操作デバイス４の上向き矢印を一回押すと（これを「リスト戻し操作」とする）、当該リスト戻し操作の操作情報がＩＣディスプレイ用操作デバイス４からＩＣデバイス３を介して操作受付部１１２に入力する。操作受付部１１２は当該操作情報を表示データ作成部１１１及び処理実行指示部１１３に出力する。表示データ作成部１１１は、リストの選択項目を前の項目に遷移して表示データを更新する。これにより、先ほどはリストの中で処理項目「２．90.0MHz」が選択項目としてアクティブに表示されていたが、今は処理項目「１．bigFM WB」が選択項目としてアクティブに表示される。また、処理実行指示部１１３では、処理項目「１．bigFM WB」の処理、すなわち「bigFM WB」の放送局への選局をラジオチューナ１２に指示する。 Next, when the user presses the upward arrow of the IC display operation device 4 once (this is referred to as “list return operation”), the operation information of the list return operation is transferred from the IC display operation device 4 to the IC device 3. To the operation reception unit 112. The operation reception unit 112 outputs the operation information to the display data creation unit 111 and the process execution instruction unit 113. The display data creation unit 111 updates the display data by changing the selection item of the list to the previous item. As a result, the processing item “2.90.0 MHz” is actively displayed as the selection item in the list earlier, but now the processing item “1. bigFM WB” is actively displayed as the selection item. In addition, the process execution instructing unit 113 instructs the radio tuner 12 to process the process item “1. bigFM WB”, that is, select a broadcast station of “bigFM WB”.
　＜Ａ－３．連続操作＞
　ＩＣディスプレイ用操作デバイス４からリストの送り戻し操作が連続して行われたとき、送り戻し操作の度に処理実行指示部１１３で選択項目の処理実行指示を行っていては、処理実行指示にかかる処理負荷のために、表示データ作成部１１１で表示データを更新する処理が遅延することが考えられる。表示データの更新処理が遅延すると、ＩＣディスプレイ用操作デバイス４を操作するユーザにとっては、送り戻し操作をしているのにリアルタイムでＩＣディスプレイ３１のリスト表示には操作が反映されないため、現在選択中の処理項目が分からなくなり、又は不快に感じることになる。この問題は、特にリスト処理装置１１が車載のヘッドユニット１に組み込まれる場合には、リスト処理装置を構成するＣＰＵの負荷が限られることが多いため顕著に生じる。 <A-3. Continuous operation>
When the list display return operation is continuously performed from the IC display operation device 4, if the process execution instruction unit 113 issues a process execution instruction for the selection item every time the return operation is performed, the process execution instruction is applied. It is conceivable that processing for updating display data in the display data creation unit 111 is delayed due to processing load. If the display data update process is delayed, the user who operates the IC display operation device 4 does not reflect the operation in the list display of the IC display 31 in real time even though the sending back operation is performed. The processing items are not understood or uncomfortable. This problem is particularly noticeable when the list processing device 11 is incorporated in the vehicle-mounted head unit 1 because the load on the CPU constituting the list processing device is often limited.
　そこで、リストの送り戻し操作が連続して行われた場合には、処理実行指示部１１３は当該連続操作において選択項目が遷移する度に処理実行を指示するのではなく、連続操作が終わったと判断した後に処理実行を指示する。具体的には、処理実行指示部１１３はタイマー機能を有しており、リストの送り戻し操作（第１の送り戻し操作）の操作情報を操作受付部１１２から取得すると、タイマーをスタートする。タイマーは、予め定めておいた判定期間の経過後に満了するものとする。そして、判定期間内に、再びリストの送り戻し操作（第３の送り戻し操作）の操作情報を操作受付部１１２から取得しなければ、第２の送り戻し操作の操作により選択された処理項目の実行を外部デバイスに指示する。しかし、判定期間内に第３の送り戻し操作の操作情報を操作受付部１１２から取得すれば、タイマーをリスタートし、再び判定期間の間、次の送り戻し操作の操作情報の取得を待機する。言い換えれば、処理実行指示部１１３は判定期間内に複数のリストの送り戻し操作が行われた場合に連続操作がなされたと判断し、連続操作が途切れるまで処理項目の実行指示を待機する。 Therefore, when the list return operation is continuously performed, the process execution instructing unit 113 determines that the continuous operation has ended, instead of instructing the process execution every time the selection item changes in the continuous operation. After that, the process execution is instructed. Specifically, the process execution instructing unit 113 has a timer function, and starts the timer when the operation information of the list sending back operation (first sending back operation) is acquired from the operation receiving unit 112. The timer expires after the elapse of a predetermined determination period. If the operation information of the list return operation (third return operation) is not acquired again from the operation accepting unit 112 within the determination period, the processing item selected by the operation of the second return operation is returned. Instructs an external device to execute. However, if the operation information of the third send-back operation is acquired from the operation reception unit 112 within the determination period, the timer is restarted and the acquisition of the operation information of the next send-back operation is awaited again during the determination period. . In other words, the process execution instructing unit 113 determines that a continuous operation has been performed when a plurality of list sending back operations are performed within the determination period, and waits for an execution instruction for process items until the continuous operation is interrupted.
　図２，３は、ラジオ局の選局リストの送り戻し操作が連続して行われた場合の、リスト処理装置１１の動作を示す図である。図２は、ＩＣディスプレイ３１の表示例とラジオチューナ１２の動作タイミングとを示し、図３は、ラジオチューナ１２の動作タイミングとセンターディスプレイ２の表示例とを示している。 2 and 3 are diagrams illustrating the operation of the list processing apparatus 11 when the operation of sending back the tuning list of the radio station is continuously performed. FIG. 2 shows a display example of the IC display 31 and an operation timing of the radio tuner 12, and FIG. 3 shows an operation timing of the radio tuner 12 and a display example of the center display 2.
　まず、ＩＣディスプレイ３１にラジオ局の選局リストが表示されており、処理項目「１．bigFM WB」が現在選択中の処理項目として色分けして表示されているものとする（図２）。このとき、センターディスプレイ２にもラジオ局の選局リストが表示されているが、その表示態様はＩＣディスプレイ３１におけるものとは異なっていても良い。一般的に、センターディスプレイ２の表示画像の情報量はＩＣディスプレイ３１の表示画像の情報量よりも多い。図３に示すように、例えばセンターディスプレイ２では、リスト表示に加えて「Select band:FM」や、選局中のラジオ局の放送番組名「Greatest Hits!」などの情報が表示される。 First, it is assumed that the channel selection list of radio stations is displayed on the IC display 31 and the processing item “1. bigFM WB” is displayed in different colors as the currently selected processing item (FIG. 2). At this time, the tuning list of radio stations is also displayed on the center display 2, but the display mode may be different from that on the IC display 31. Generally, the information amount of the display image on the center display 2 is larger than the information amount of the display image on the IC display 31. As shown in FIG. 3, in the center display 2, for example, in addition to the list display, information such as “Select band: FM” and the broadcast program name “Greatest Hits!” Of the selected radio station is displayed.
　ここで、ユーザがハンドルリモコンの下カーソルキーを押下げると、当該操作情報がＩＣデバイス３、操作受付部１１２を介して処理実行指示部１１３と表示データ作成部１１１に入力される。処理実行指示部１１３は、当該操作情報を受けてタイマーをスタートし、判定期間（ここでは５００ｍｓとする）を経過する前に、次の送り戻し操作がなされるか否かを判断する。ここで、処理実行指示部１１３は、タイマースタートと合わせて処理項目「２．90.0 MHz」の選局処理をラジオチューナ１２に指示する。一方、表示データ作成部１１１は取得した操作情報に応じてＩＣディスプレイ３１用の表示データを更新する。こうして、ＩＣディスプレイ３１では「２．90.0 MHz」が選択中の処理項目として、色分けして表示される。 Here, when the user depresses the lower cursor key of the handle remote controller, the operation information is input to the process execution instructing unit 113 and the display data creating unit 111 via the IC device 3 and the operation receiving unit 112. The process execution instructing unit 113 receives the operation information, starts a timer, and determines whether or not the next sending back operation is performed before the determination period (here, 500 ms) elapses. Here, the process execution instructing unit 113 instructs the radio tuner 12 to perform the channel selection process of the process item “2.90.0 MHz” together with the timer start. On the other hand, the display data creation unit 111 updates the display data for the IC display 31 according to the acquired operation information. Thus, on the IC display 31, “2.90.0ＩＣMHz” is displayed as a color-coded process item being selected.
　タイマー開始から５００ｍｓを経過する前にユーザがハンドルリモコンの下カーソルキーを再び押下げると、当該操作情報がＩＣデバイス３、操作受付部１１２を介して処理実行指示部１１３と表示データ作成部１１１に入力される。処理実行指示部１１３は当該操作情報を受けてタイマーをリスタート（１回目）するが、処理項目「３．99.0 MHz」の選局処理をラジオチューナ１２に指示することはない。一方、表示データ作成部１１１は取得した操作情報に応じて表示データを更新する。こうして、ＩＣディスプレイ３１では「３．99.0 MHz」が選択中の処理項目として、色分けして表示される。ここで、表示データ作成部１１１は、センターディスプレイ２用の表示データの更新は行わないこととする。もちろん、センターディスプレイ２用の表示データの更新を行うことも可能であるが、ＩＣディスプレイ３１用の表示データのみ更新することにより、ＣＰＵの処理負荷が少なくてすみ、リストの送り戻し操作が連続して行われる場合であっても、ＩＣディスプレイ３１の表示更新を遅延なく行うことが可能になる。 If the user depresses the lower cursor key of the handle remote control again before 500 ms elapses from the start of the timer, the operation information is transferred to the process execution instruction unit 113 and the display data creation unit 111 via the IC device 3 and the operation reception unit 112. Entered. The process execution instructing unit 113 receives the operation information and restarts the timer (first time), but does not instruct the radio tuner 12 to select the process item “3.99.0 MHz”. On the other hand, the display data creation unit 111 updates the display data according to the acquired operation information. Thus, on the IC display 31, “3.99.0 MHz” is displayed as a color-coded process item being selected. Here, the display data creation unit 111 does not update the display data for the center display 2. Of course, it is possible to update the display data for the center display 2, but by updating only the display data for the IC display 31, the processing load on the CPU can be reduced and the list return operation can be continued. Even if it is performed, the display update of the IC display 31 can be performed without delay.
　タイマーリスタート（１回目）から５００ｍｓを経過する前に、ユーザがハンドルリモコンの下カーソルキーを再び押下げると、当該操作情報がＩＣデバイス３、操作受付部１１２を介して処理実行指示部１１３と表示データ作成部１１１に入力される。処理実行指示部１１３は当該操作情報を受けてタイマーをリスタート（２回目）するが、処理項目「４．100.0 MHz」の選局処理をラジオチューナ１２に指示することはない。一方、表示データ作成部１１１は取得した操作情報に応じて表示データを更新する。こうして、ＩＣディスプレイ３１では「４．100.0 MHz」が選択中の処理項目として、色分けして表示される。 If the user depresses the lower cursor key of the handle remote control again before 500 ms elapses from the timer restart (first time), the operation information is transferred to the process execution instruction unit 113 via the IC device 3 and the operation reception unit 112. Input to the display data creation unit 111. The process execution instructing unit 113 receives the operation information and restarts the timer (second time). However, the process execution instructing unit 113 does not instruct the radio tuner 12 to select the channel of the process item “4.100.0 MHz”. On the other hand, the display data creation unit 111 updates the display data according to the acquired operation information. Thus, on the IC display 31, “4.100.0 MHz” is displayed in a color-coded manner as the selected processing item.
　タイマーリスタート（２回目）から５００ｍｓを経過しても、ユーザによるリストの送り戻し操作が行われなければ、処理実行指示部１１３は、処理項目「４．100.0 MHz」の選局処理をラジオチューナ１２に指示する。そして、ラジオチューナ１２は選局処理を行ってラジオ局から情報を取得し、選局処理が完了する。その後、表示データ作成部１１１は、ラジオチューナ１２が選局処理で取得した情報を用いてセンターディスプレイ２用の表示データ（描画データ）を作成し、センターディスプレイ２に出力する。こうして、センターディスプレイ２では「100.0 MHz」の放送局の放送番組名「World News」等の情報が表示される（図３）。 If the user does not perform a list return operation even after 500 ms from the timer restart (second time), the process execution instructing unit 113 performs the channel selection process for the process item “4.100.0 MHz” with the radio tuner. 12 is instructed. Then, the radio tuner 12 performs a channel selection process to acquire information from the radio station, and the channel selection process is completed. Thereafter, the display data creation unit 111 creates display data (drawing data) for the center display 2 using information acquired by the radio tuner 12 through the channel selection process, and outputs the display data to the center display 2. Thus, the center display 2 displays information such as the broadcast program name “World News” of the broadcasting station “100.0 MHz” (FIG. 3).
　以上の動作により、ユーザがリストの送り戻し操作を連続して行った場合、連続操作の最中には選択項目の処理指示を行わず、ＩＣディスプレイ３１の表示更新のみが行われる。そのため、リスト処理装置１１のＣＰＵ負荷が限られていても、選択項目の処理指示に負荷を割く必要がないため、ＩＣディスプレイ３１の表示更新が遅延することが抑制できる。従って、ユーザにとっては自己の操作に連動してＩＣディスプレイの表示更新が行われるため、不快に感じることがない。 By the above operation, when the user continuously performs the list sending back operation, the selection item processing instruction is not performed during the continuous operation, and only the display update of the IC display 31 is performed. For this reason, even if the CPU load of the list processing device 11 is limited, it is not necessary to allocate a load to the processing instruction of the selection item, so that it is possible to suppress delay in the display update of the IC display 31. Therefore, since the display update of the IC display is performed in conjunction with the user's operation, the user does not feel uncomfortable.
　なお、タイマーの判定期間は、上述の説明では５００ｍｓとしたが、この値は予め定めておき処理実行指示部１１３内のメモリに格納しておく。あるいは、ユーザがリストの送り戻し操作を連続して行うタイミングから、学習しても良い。具体的には、初期設定として例えば判定期間を５００ｍｓに設定した上で、ユーザがリストの送り戻し操作を２００ｍｓ間隔で連続して行い、２００ｍｓ間隔での送り戻し操作が所定回数以上繰り返された場合には、判定期間を２００ｍｓに余裕期間の５０ｍｓを付加して２５０ｍｓに更新しても良い。また、センターディスプレイ２やＩＣディスプレイ３１に判定期間の設定画面を表示し、ユーザに直接判定期間を入力させても良い。 Although the timer determination period is 500 ms in the above description, this value is determined in advance and stored in the memory in the process execution instruction unit 113. Or you may learn from the timing which a user performs sending back operation | movement of a list | wrist continuously. Specifically, for example, when the determination period is set to 500 ms as an initial setting, the user continuously performs a list return operation at intervals of 200 ms, and the return operation at intervals of 200 ms is repeated a predetermined number of times or more. Alternatively, the determination period may be updated to 250 ms by adding a margin period of 50 ms to 200 ms. Alternatively, the determination period setting screen may be displayed on the center display 2 or the IC display 31 to allow the user to directly input the determination period.
　図４，５は、ＵＳＢ１４に接続される外部デバイスのメディアプレーヤの選曲リストの送り戻し操作が連続して行われた場合の、リスト処理装置１１の動作を示す図である。図４は、ＩＣディスプレイ３１の表示例とラジオチューナ１２の動作タイミングとを示し、図５は、メディアプレーヤの動作タイミングとセンターディスプレイ２の表示例とを示している。基本的な動作の概要は図２，３と同様であるので、図４，５の説明は省略する。本発明は、ラジオの放送局リストやメディアプレーヤの選曲リストに限らず、リスト処理装置１１の外部デバイスから取得するリストの送り戻し操作に対して適用される。 4 and 5 are diagrams showing the operation of the list processing apparatus 11 when the music player list sending back operation of the media player of the external device connected to the USB 14 is continuously performed. 4 shows a display example of the IC display 31 and an operation timing of the radio tuner 12, and FIG. 5 shows an operation timing of the media player and a display example of the center display 2. The outline of the basic operation is the same as that shown in FIGS. The present invention is not limited to a radio broadcast station list or a media player music selection list, but is applied to a list sending back operation acquired from an external device of the list processing apparatus 11.
　図６は、リストの送り戻し操作の操作情報を取得した処理実行指示部１１３の動作を示すフローチャートである。処理実行指示部１１３は、ＩＣディスプレイ用操作デバイス４におけるリストの送り戻し操作の操作情報を取得すると、タイマーをスタートし、選択されたリストの処理項目の処理の実行を外部デバイスに指示する（ステップＳ１）。次に、判定期間が経過したか否かを判断する（ステップＳ２）。判定期間が未経過であれば（ステップＳ２でＮｏ）、送り戻し操作の操作情報を再び取得したか否かを判断する（ステップＳ４）。送り戻し操作の操作情報を取得していなければ、ステップＳ２に戻り、再びタイマースタート(ステップＳ１)から判定期間が未経過であるかを判断する。判定期間が未経過のうちに、送り戻し操作の操作情報を再び取得した場合は、連続操作が行われていると判断し、タイマーをキャンセル（ステップＳ５）して再びタイマーをスタートする（ステップＳ１）。すなわち、タイマーのリスタートを行う。一方、送り戻し操作の操作情報を取得することなくタイマーの判定期間が経過した場合は（ステップＳ２でＹｅｓ）、最後に操作情報を取得した送り戻し操作により選択されたリストの処理項目の処理の実行を、外部デバイスに指示する（ステップＳ３）。 FIG. 6 is a flowchart showing the operation of the process execution instructing unit 113 that has acquired the operation information of the list return operation. When the process execution instructing unit 113 acquires the operation information of the list sending back operation in the IC display operation device 4, the process execution instructing unit 113 starts a timer and instructs the external device to execute the process of the processing item of the selected list (step S1). Next, it is determined whether the determination period has elapsed (step S2). If the determination period has not elapsed (No in step S2), it is determined whether or not the operation information of the return operation has been acquired again (step S4). If the operation information of the return operation has not been acquired, the process returns to step S2, and it is determined again whether the determination period has not elapsed since the timer start (step S1). If the operation information of the return operation is acquired again before the determination period has elapsed, it is determined that the continuous operation is performed, the timer is canceled (step S5), and the timer is started again (step S1). ). That is, the timer is restarted. On the other hand, when the determination period of the timer has elapsed without acquiring the operation information of the return operation (Yes in step S2), the processing of the processing item of the list selected by the return operation that acquired the operation information last is performed. Execution is instructed to the external device (step S3).

　＜Ａ－５．効果＞
　本発明の実施の形態１に係るリスト処理装置１１は、複数の処理項目を順番に並べたリストを表示装置（ＩＣディスプレイ３１、センターディスプレイ２）に表示するための表示データを作成する表示データ作成部１１１と、リストの送り戻しによって処理項目を順番に沿って選択するユーザの送り戻し操作を受け付ける操作受付部１１２と、第１の送り戻し操作を受け付けると、第１の送り戻し操作で選択された処理項目の処理の実行を指示し、第１の送り戻し操作の受付から予め定めた判定期間内に第２の送り戻し操作を受け付けた場合に、第２の送り戻し操作で選択された処理項目の処理の実行を指示せず、判定期間内に第３の送り戻し操作を受け付けない場合に、第２の送り戻し操作で選択された処理項目の処理を指示する処理実行指示部１１３と、を備える。従って、送り戻し操作が連続して行われる場合は、連続操作の最後の操作で選択された処理項目の処理の実行の指示のみが行われるので、処理負荷を軽減することができる。また、タイマー開始と共に選択された処理項目を実行することで、連続した送り戻し操作ではない場合は項目選択後すぐに選択された処理項目の処理の実行が指示される。 <A-5. Effect>
The list processing device 11 according to Embodiment 1 of the present invention creates display data for creating display data for displaying a list in which a plurality of processing items are arranged in order on a display device (IC display 31, center display 2). Unit 111, operation accepting unit 112 that accepts a user's send-back operation for selecting processing items in order by list-feedback, and when a first send-back operation is accepted, it is selected by the first send-back operation. The process selected by the second send-back operation when the execution of the process of the process item is instructed and the second send-back operation is received within a predetermined determination period from the reception of the first send-back operation. Execution of processing for instructing processing of the processing item selected in the second sending-back operation when not instructing execution of item processing and not accepting the third sending-back operation within the determination period It includes a radical 113 113, a. Therefore, when the sending back operation is continuously performed, only the instruction to execute the processing of the processing item selected in the last operation of the continuous operation is performed, so that the processing load can be reduced. Also, by executing the selected process item when the timer is started, execution of the process of the selected process item is instructed immediately after the item is selected if it is not a continuous sending back operation.
　また、表示データ作成部１１１は、送り戻し操作を受け付ける度、送り戻し操作に基づき表示データを更新する。送り戻し操作が連続して行われる場合は、連続操作の最後の操作で選択された処理項目の処理の実行の指示のみが行われるので、処理負荷を軽減することができ、表示データの更新の遅延を抑制することが可能である。 Further, the display data creation unit 111 updates the display data based on the sending back operation every time the sending back operation is accepted. When sending back operations are performed continuously, only the instruction to execute the processing of the processing item selected in the last operation of the continuous operation is performed, so the processing load can be reduced and the display data can be updated. It is possible to suppress the delay.
　リスト処理装置が処理対象とするリストが、放送局の選局リスト（放送局データの選択リスト）や、映像データ又は音楽データの再生リスト（選択リスト）等、リスト処理装置の外部のデバイスから取得するリストである場合には、表示データの作成や処理項目の処理指示に時間がかかるため、処理負荷を軽減できる本発明の効果が大きい。しかし、リスト処理装置の内部メモリに記憶されたリストであっても良い。リストの他の例としては、地点・施設データ、通信データ（メール、アドレス、ＵＲＬ、ＴＥＬ番号等）のリストが挙げられる。 A list to be processed by the list processing device is acquired from a device outside the list processing device, such as a broadcasting station tuning list (broadcasting station data selection list) or a video data or music data playback list (selection list). In the case of a list to be processed, it takes time to create display data and to instruct processing of processing items, so the effect of the present invention that can reduce the processing load is great. However, it may be a list stored in the internal memory of the list processing apparatus. Other examples of the list include a list of point / facility data and communication data (email, address, URL, TEL number, etc.).
　また、上記判定期間はユーザが指定可能とすることにより、ユーザの個人差に合わせた制御を行うことが出来る。 In addition, by making it possible for the user to specify the determination period, it is possible to perform control according to individual differences of the user.
　特に、リスト処理装置１１が車両に搭載される場合、リスト処理装置１１を構成するＣＰＵの処理性能が限られている場合が多い。表示装置をＩＣディスプレイ３１とする場合、ＩＣディスプレイ３１に表示されるリストは、その送り戻し操作が行われる度に処理項目が選択される仕様となっている場合があるが、このような場合でも、選択された処理項目の処理実行を連続操作の間は行わないことにより、ＣＰＵの処理性能が限られていても、リストの表示更新の遅延を抑制することができる。 In particular, when the list processing device 11 is mounted on a vehicle, the processing performance of the CPU constituting the list processing device 11 is often limited. When the display device is the IC display 31, the list displayed on the IC display 31 may have a specification in which a processing item is selected every time the return operation is performed. By not executing the processing of the selected processing item during the continuous operation, it is possible to suppress the delay of the list display update even if the processing performance of the CPU is limited.
　また、本発明の実施の形態１に係るリスト処理方法は、複数の処理項目を順番に並べたリストを表示装置に表示するための表示データを作成し、リストの送り戻しによって処理項目を順番に沿って選択するユーザの送り戻し操作を受け付け、第１の送り戻し操作を受け付けると、第１の送り戻し操作で選択された処理項目の処理の実行を指示し、予め定めた判定期間内に第２の送り戻し操作を受け付けた場合に、第２の送り戻し操作で選択された処理項目の処理の実行を指示せず、判定期間内に第３の送り戻し操作を受け付けない場合に、第２の送り戻し操作で選択された処理項目の処理の実行を指示する。従って、送り戻し操作が連続して行われる場合は、連続操作の最後の操作で選択された処理項目の処理の実行のみを指示するので、処理負荷を軽減することができる。また、タイマー開始と共に選択された処理項目を実行することで、連続した送り戻し操作ではない場合は項目選択後すぐに選択された処理項目の処理の実行が指示される。 The list processing method according to the first embodiment of the present invention creates display data for displaying a list in which a plurality of processing items are arranged in order on the display device, and sequentially processes the processing items by sending back the list. When a user's send-back operation to be selected is accepted and the first send-back operation is accepted, execution of the processing of the process item selected by the first send-back operation is instructed, and within a predetermined determination period, When the second send-back operation is accepted, the second item is not instructed to execute the process selected by the second send-back operation, and the second send-back operation is not accepted within the determination period. Instructs execution of the processing of the processing item selected by the send-back operation. Therefore, when the sending back operation is continuously performed, only the execution of the processing of the processing item selected in the last operation of the continuous operation is instructed, so that the processing load can be reduced. Also, by executing the selected process item when the timer is started, execution of the process of the selected process item is instructed immediately after the item is selected if it is not a continuous sending back operation.
