Abstract

Provided are a volume control method, a volume control device, and an imaging device, which make it possible to return the ratio between the volume change amount and the level change amount to 1:1 when a function is switched by a switch, and to perform operation without discomfort. When a switch 41 is once switched from a selected function to select a function before the switching, a level stored in a memory 43 is read. A point specified by said level and the scale of a current volume is set as a current operating point 102, and a line connecting said operating point 102 and a minimum point or a line connecting said operating point and a maximum point is set as the locus of the operating point 102. When the operating point 102 enters a midpoint matching area 101, the locus is changed such that the operating point 102 passes a midpoint 103 of a line in the initial state connecting the minimum point and the maximum point, and after the operating point 102 passes the midpoint 103, the locus is returned to the locus in the initial state.

Description

ボリュームの制御方法、ボリュームの制御装置及び撮像装置Volume control method, volume control device and imaging device
　本発明は、複数の調整項目をスイッチで切り替えるボリュームの制御方法に係り、特に、ボリュームとレベルの変化量を１：１の状態に迅速に戻すことができるボリュームの制御方法、ボリュームの制御装置及び撮像装置に関する。 The present invention relates to a volume control method of switching a plurality of adjustment items by a switch, and in particular, a volume control method capable of quickly returning volume and level change amounts to a 1: 1 state, volume control device, and The present invention relates to an imaging device.
［従来の技術］ 　電子機器に用いられるアナログ量調整ボリュームは、複雑な操作をすることなく設定値を調整できるため、様々な電子機器に広く利用されている。
　従来の調整用ボリュームは、調整項目数と同じ数だけ必要になるため、調整項目数が多いほどボリューム数も多く配置しなければならなかった。
　しかしながら、電子機器は小型化が求められ、配置できるボリューム数に限界がある。 [Prior Art] An analog amount adjustment volume used in an electronic device can be used to adjust setting values without performing complicated operations, and thus is widely used in various electronic devices.
Since the conventional adjustment volume requires the same number as the number of adjustment items, the larger the number of adjustment items, the more the number of volumes had to be arranged.
However, electronic devices are required to be miniaturized, and the number of volumes that can be arranged is limited.
　そこで、複数の調整項目を、スイッチとボリュームを組み合わせて調整することにより、ボリューム数の限界を克服する提案が為されている（例えば、下記の特許文献１，２）。 Therefore, proposals have been made to overcome the limit of the number of volumes by adjusting a plurality of adjustment items by combining a switch and a volume (for example, Patent Documents 1 and 2 below).
［関連技術］ 　尚、関連する先行技術として、特開平０８－００８６６３号公報「電子ボリュームの拡張方法」（特許文献１）、特開２００７－２５１７１３号公報「ボリュームの制御方法、ボリュームの制御装置および撮像装置」（特許文献２）がある。 [Related Art] As related prior art, Japanese Patent Application Laid-Open No. 08-008663 "Expansion method of electronic volume" (patent document 1), Japanese Patent Application Laid-Open No. 2007-251713 "Volume control method, volume control apparatus and device There is an imaging device "(patent document 2).
　特許文献１には、電子ボリュームの入力側と出力側に連動するスイッチを設け、入力信号が切り替わると、電子ボリュームの設定情報をメモリに保持し、元の入力信号に切り替わるとメモリから設定情報を読み出して設定することが示されている。これにより、複数の調整項目を１つの電子ボリュームで実現できるものである。 In Patent Document 1, there are provided switches interlocking with the input side and output side of the electronic volume, and when the input signal is switched, the setting information of the electronic volume is held in the memory, and when switched to the original input signal, the setting information is output from the memory Reading and setting are shown. Thereby, a plurality of adjustment items can be realized by one electronic volume.
　特許文献２には、スイッチで選択された調整項目のレベルをメモリから読み出し、共通ボリュームの現在の目盛位置と読み出したレベルから共通ボリュームの単位変化量に対するレベルの変化量の割合を算出し、共通ボリュームの上下動があると現在のレベルをメモリに保持することが示されている。これにより、調整項目より少ないボリューム数で各調整項目のレベルの全レンジをカバーできる。 In Patent Document 2, the level of the adjustment item selected by the switch is read from the memory, and the ratio of the level change amount to the unit change amount of the common volume is calculated from the current scale position of the common volume and the read level. Up and down movement of the volume is shown to keep the current level in memory. Thereby, the entire range of the level of each adjustment item can be covered with the number of volumes smaller than the adjustment item.
　特許文献１においては、ボリュームの単位変化量に対するレベルの変化量が常に一定であるため、ボリューム調整でレベルの全レンジをカバーできない場合があった。
　これに対して、特許文献２では、調整項目よりも少ないボリューム数で各調整項目のレベルの全レンジをカバーすることが可能なボリュームの制御方法が提案されている。 In Patent Document 1, there is a case where the volume adjustment can not cover the entire range of the level because the amount of change of the level to the unit change of the volume is always constant.
On the other hand, Patent Document 2 proposes a volume control method capable of covering the entire range of the level of each adjustment item with the number of volumes smaller than the adjustment item.
　具体的には、特許文献１では、ボリュームの変化量とレベルの変化量が常に１：１では、切り替えたボリュームの位置によってレベルの最小値から最大値まで制御することができなくなる。
　それに対して、特許文献２では、ボリュームの変化量に対し、値の変化量を変化させることで対応するものとなっている。 Specifically, in Patent Document 1, when the amount of change in volume and the amount of change in level are always 1: 1, control can not be performed from the minimum value to the maximum value of the level depending on the position of the switched volume.
On the other hand, in Patent Document 2, the amount of change in volume is dealt with by changing the amount of change in value.

　しかしながら、上記従来例のボリュームの制御方法では、ボリュームとレベルの変化量を１：１に戻すには、ボリュームを最大（ＭＡＸ）又は最小（ＭＩＮ）にする必要があり、１：１の状態になるまで手間が掛かってしまうことになるという問題点があった。 However, in the above-described conventional volume control method, in order to return the volume and level change amount to 1: 1, the volume needs to be maximized (MAX) or minimized (MIN). There was a problem that it took time and effort until it became.
　また、特許文献２では、ボリュームが制御する機能をスイッチにより切り替えた際に、ボリュームの目盛が極端に大きい位置、もしくは極端に小さい位置となった場合、その逆にそのレベル（設定値）が極端に小さい、もしくは極端に大きい場合に、ボリュームの目盛の変化量に対してレベルの変動が大きく、ユーザの想定よりも大きな変化を招いてしまうことがあった。 Further, in Patent Document 2, when the function controlled by the volume is switched by the switch, when the scale of the volume is at an extremely large position or an extremely small position, the level (setting value) is extremely extreme. When it is small or extremely large, the fluctuation of the level is large with respect to the amount of change of the volume scale, which may cause a change larger than the user's assumption.
　特許文献１，２には、ボリュームとレベルの変化量を迅速に１：１に戻すことについて記載がない。
　また、特許文献１，２には、ボリュームが制御する機能をスイッチで切り替えた場合に、大幅な変化による予期せぬ動作を防止することについて記載がない。 Patent Literatures 1 and 2 do not describe that the volume and level change amounts are quickly returned to 1: 1.
In addition, Patent Documents 1 and 2 do not describe about preventing unexpected operation due to a significant change when the function controlled by the volume is switched by a switch.
　本発明は上記実情に鑑みて為されたもので、調整機能をスイッチで切り替えた場合に、ボリュームとレベルの変化量を迅速に１：１に戻すことができ、違和感なく操作できるボリュームの制御方法、ボリュームの制御装置及び撮像装置を提供することを目的とする。 The present invention has been made in view of the above situation, and when the adjustment function is switched by a switch, the volume and level change amount can be quickly returned to 1: 1, and a volume control method that can be operated without discomfort It is an object of the present invention to provide a volume control device and an imaging device.
　また、本発明は、上記目的に加え、ボリュームが制御する機能をスイッチで切り替えた場合に、大幅なレベル変化による予期せぬ動作を防止し、ユーザに安定した操作感を与えることを可能とするものである。 Further, in addition to the above object, the present invention can prevent unexpected operation due to a significant level change and give a stable sense of operation to the user when the function controlled by volume is switched by a switch. It is a thing.
　上記従来例の問題点を解決するための本発明は、複数の機能をスイッチで切り替えて、機能に応じてレベルを共通のボリュームで制御する制御方法であって、ボリュームの目盛とレベルの関係を平面で表した場合に、目盛とレベルが最小となる最小点の近辺エリア又は／及び最大となる最大点の近辺エリアを中点合致エリアとして設定し、スイッチが選択した機能の切替前のレベルをメモリに記憶しておき、一旦スイッチが切り替えられた後に、スイッチが切替前の機能を選択すると、メモリに記憶されたレベルを読み込み、当該レベルと現在のボリュームの目盛で特定される点を現在の操作点として、操作点と最小点とを結んだ線又は操作点と最大点とを結んだ線の線上を操作点の軌道とし、ボリュームの操作で操作点が中点合致エリアに入ると、最小点と最大点とを結ぶ初期状態の線の中点を操作点が通過する軌道とし、中点を操作点が通過すると、初期状態の線上を操作点の軌道とすることを特徴とする。 The present invention for solving the problems of the above-mentioned conventional example is a control method of switching a plurality of functions by switches and controlling the level with a common volume according to the functions, wherein the relationship between the scale of the volume and the level is When expressed in a plane, the area near the minimum point where the scale and level are minimum or / and the area near the maximum point where the maximum is maximum are set as the midpoint match area, and the level before switching of the function selected by the switch is set. Once stored in memory and the switch is switched, once the switch selects the function before switching, the level stored in memory is read, and the point specified by the level and the scale of the current volume is The operation point is a line connecting the operation point and the minimum point or a line connecting the operation point and the maximum point as the trajectory of the operation point. When entering, the middle point of the line in the initial state connecting the minimum point and the maximum point is taken as the trajectory through which the operating point passes, and when the operating point passes through the middle point, the line in the initial state is taken as the trajectory of the operating point. I assume.
　本発明は、上記ボリームの制御方法において、ボリュームの目盛とレベルの関係を平面で表した場合に、レベルの急激な変動を抑制する急峻制御禁止エリアを設け、操作点が急峻制御禁止エリアに入ると、操作点からの軌道変動を制限することを特徴とする。 According to the present invention, in the control method of the above-mentioned volume, when the relationship between the scale of the volume and the level is represented by a plane, an abrupt control inhibition area is provided which suppresses abrupt fluctuations of the level, and the operation point falls within the abrupt control inhibition area. And, it is characterized by limiting the orbital fluctuation from the operation point.
　本発明は、複数の機能を切り替えるスイッチと、複数の機能のレベルを制御する共通のボリュームと、機能毎にスイッチの切替前のレベルを記憶し、ボリュームの目盛とレベルの関係を平面で表した場合に、目盛とレベルが最小となる最小点の近辺エリア又は／及び最大となる最大点の近辺エリアを中点合致エリアとして設定されているメモリと、スイッチが選択した機能から一旦切り替えられて、切替前の機能を選択すると、メモリに記憶されたレベルを読み込み、当該レベルと現在のボリュームの目盛で特定される点を現在の操作点として、当該操作点と最小点とを結んだ線又は操作点と最大点とを結んだ線の線上を操作点の軌道とし、ボリュームの操作で操作点が中点合致エリアに入ると、最小点と最大点とを結ぶ初期状態の線の中点を操作点が通過する軌道とし、中点を操作点が通過すると、初期状態の線上を操作点の軌道とするよう制御を行うレベル調整部とを有することを特徴とする。 The present invention stores a switch that switches a plurality of functions, a common volume that controls the levels of the plurality of functions, and a level before switching of the switch for each function, and expresses the relationship between the scale of the volume and the level in a plane. If the scale and the area near the minimum point where the scale and level are minimum or / and the area near the maximum point where the maximum is maximum are set as the midpoint match area and the switch is switched once from the selected function, When the function before switching is selected, the level stored in the memory is read, and a line or operation connecting the operation point and the minimum point with the point specified by the level and the scale of the current volume as the current operation point Let the line connecting the point and the maximum point be the trajectory of the operation point. When the operation point enters the middle point match area by volume operation, inside the initial state line connecting the minimum and maximum points And track the operating point passes, when the middle point operating point passes, and having a level adjusting section for performing control such that the line of initial states and path of the operating point.
　本発明は、上記ボリームの制御装置において、メモリには、ボリュームの目盛とレベルの関係を平面で表した場合に、レベルの急激な変動を抑制する急峻制御禁止エリアが設けられ、レベル調整部が、操作点が急峻制御禁止エリアに入ると、操作点からの軌道変動を制限することを特徴とする。 According to the present invention, in the control apparatus of the above-mentioned volume, the memory is provided with a steep control prohibition area for suppressing a rapid change of the level when the relationship between the scale of the volume and the level is represented by a plane. When the operation point is in the steep control prohibition area, it is characterized in that the orbital fluctuation from the operation point is limited.
　本発明は、撮像装置において、上記ボリームの制御装置と、ボリュームの目盛とレベルの関係を平面とし、操作点の軌道を表示する表示部とを有することを特徴とする。 The present invention is characterized in that the image pickup apparatus has a control device of the above-mentioned volume, and a display section which makes the relationship between the scale of the volume and the level a plane, and displays the trajectory of the operation point.
　本発明によれば、一旦スイッチが切り替えられた後に、スイッチが切替前の機能を選択すると、メモリに記憶されたレベルを読み込み、当該レベルと現在のボリュームの目盛で特定される点を現在の操作点として、操作点と最小点とを結んだ線又は操作点と最大点とを結んだ線の線上を操作点の軌道とし、ボリュームの操作で操作点が中点合致エリアに入ると、最小点と最大点とを結ぶ初期状態の線の中点を操作点が通過する軌道とし、中点を操作点が通過すると、初期状態の線上を操作点の軌道とするボリュームの制御方法としているので、機能をスイッチで切り替えた場合に、ボリュームとレベルの変化量を迅速に１：１に戻すことができ、違和感なく操作できる効果がある。 According to the present invention, once the switch is switched, once the switch selects the function before switching, the level stored in the memory is read, and the point specified by the level and the scale of the current volume is the current operation. The trajectory of the operating point is the line connecting the operating point and the minimum point, or the line connecting the operating point and the maximum point, and the minimum point when the operating point enters the middle point match area by volume operation. Since the middle point of the line in the initial state connecting と and the maximum point is the trajectory through which the operating point passes, and when the operating point passes the middle point, the control method of the volume is the trajectory of the operating point on the line in the initial state. When the function is switched by a switch, the amount of change in volume and level can be quickly returned to 1: 1, and there is an effect that the user can operate without discomfort.

Outline of Embodiment A control method of volume according to an embodiment of the present invention is to switch a plurality of functions by a switch and control a level by a common volume according to the functions, and the switch selects Once the function is switched and the function before switching is selected, the level stored in the memory is read, and the point specified by the level and the scale of the current volume is taken as the current operation point, the operation point and the minimum point And the line connecting the operation point and the maximum point are taken as the trajectory of the operation point, and when the operation point enters the middle point match area by the operation of the volume, the initial state connecting the minimum point and the maximum point The middle point of the line is taken as the trajectory through which the operation point passes, and when the operation point passes the midpoint, it is returned to the initial state trajectory, so when the function is switched by a switch, the volume and level changes The amount quickly 1: can be returned to 1, in which can be operated without discomfort.

［本装置：図１］ 　本発明の実施の形態に係るボリームの制御装置（本装置）について図１を参照しながら説明する。図１は、本装置の構成ブロック図である。
　本装置は、図１に示すように、機能Ａ制御部１０と、機能Ｂ制御部２０と、機能Ｚ制御部３０と、ボリューム４０と、スイッチ４１と、切替制御部４２と、メモリ４３とを基本的に有している。
　尚、機能Ｂ制御部２０と機能Ｚ制御部３０との間には、複数の機能制御部が設けられている。 [Present Device: FIG. 1] A control device of a volume (present device) according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram of the apparatus.
This apparatus, as shown in FIG. 1, includes a function A control unit 10, a function B control unit 20, a function Z control unit 30, a volume 40, a switch 41, a switching control unit 42, and a memory 43. Basically it has.

　各機能Ａ～Ｚ制御部１０～３０は、各制御対象Ａ～Ｚに対してレベル調整を行うものである。
　各レベル調整部１１～３１には、メモリ４３から機能設定値がセットされ、制御対象のレベルを制御する。
　切替制御部４２は、スイッチ４１を切り替え、ボリューム４０を選択したレベル調整部１１～３１に接続する。 The respective functions A to Z control units 10 to 30 perform level adjustment on the respective control objects A to Z.
A function setting value is set in each of the level adjusters 11 to 31 from the memory 43 to control the level of the control target.
The switching control unit 42 switches the switch 41 and connects the volume 40 to the selected level adjustment units 11 to 31.
［本装置の各部］ 　本装置の各部について具体的に説明する。
　機能Ａ制御部１０は、１番目の機能Ａに対する制御部であり、レベル調整部１１と、制御対象Ａ１２とを備えている。
　レベル調整部１１は、制御対象Ａの機能に応じて、メモリ４３から機能Ａ用の設定値がセットされ、ボリューム４０が接続されている場合には、その設定値でレベル調整を行う。 [Each part of this device] Each part of this device will be explained concretely.
The function A control unit 10 is a control unit for the first function A, and includes a level adjustment unit 11 and a control target A12.
The level adjustment unit 11 sets a setting value for the function A from the memory 43 according to the function of the control target A, and when the volume 40 is connected, performs level adjustment with the setting value.
　機能Ｂ制御部２０は、２番目の機能Ｂに対する制御部であり、レベル調整部２１と、制御対象Ｂ２２とを備えている。
　レベル調整部２１は、制御対象Ｂの機能に応じて、メモリ４３から機能Ｂ用の設定値がセットされ、ボリューム４０が接続されている場合には、その設定値を用いてボリューム４０の値に応じてレベル調整を行う。 The function B control unit 20 is a control unit for the second function B, and includes a level adjustment unit 21 and a control target B22.
The level adjustment unit 21 sets the setting value for the function B from the memory 43 according to the function of the control target B, and when the volume 40 is connected, the value is used as the value of the volume 40 when the volume 40 is connected. Adjust the level accordingly.
　機能Ｚ制御部３０は、Ｎ（Ｎは任意の整数）番目の機能Ｚに対する制御部であり、レベル調整部３１と、制御対象Ｚ３２とを備えている。
　レベル調整部３１は、制御対象Ｚの機能に応じて、メモリ４３から機能Ｚ用の設定値がセットされ、ボリューム４０が接続されている場合には、その設定値でレベル調整を行う。 The function Z control unit 30 is a control unit for the Nth (N is an arbitrary integer) function Z, and includes a level adjustment unit 31 and a control target Z32.
The level adjustment unit 31 sets a setting value for the function Z from the memory 43 according to the function of the control target Z, and when the volume 40 is connected, performs level adjustment with the setting value.
　ボリューム４０は、機能Ａ～Ｚ制御部１０～３０に対する共通ボリュームとなっており、スイッチ４１の動作によって接続するレベル調整部１１～３１が切り替えられる。
　スイッチ４１は、各レベル調整部とボリューム４０との接続を切り替えるセレクタである。 The volume 40 is a common volume for the functions A to Z control units 10 to 30, and the level adjustment units 11 to 31 to be connected are switched by the operation of the switch 41.
The switch 41 is a selector that switches the connection between each level adjustment unit and the volume 40.
　切替制御部４２は、スイッチ４１の切り替えを制御する。切り替え制御は、操作によって行ってもよいし、何らかの信号を検出して自動的に切り替え制御を行ってもよい。
　メモリ４３は、機能Ａ～Ｚ制御部１０～３０に対する設定値を記憶している。設定値は、機能毎にボリューム目盛に対応するレベルの値、もしくはレベルの値を算出する式となる。
　また、メモリ４３には、スイッチ４１が切り替わったときのレベルの値をレベル調整部毎に記憶している。 The switching control unit 42 controls switching of the switch 41. The switching control may be performed by operation, or switching control may be performed automatically by detecting some signal.
The memory 43 stores setting values for the functions A to Z control units 10 to 30. The setting value is an expression for calculating the value of the level corresponding to the volume scale or the value of the level for each function.
The memory 43 stores, for each level adjustment unit, the value of the level when the switch 41 is switched.
　本装置は、基本的には、ボリューム４０に接続するレベル調整部１１～３１がボリューム４０の値を入力し、メモリ４３から設定された設定値によってレベル調整を行って制御対象への制御を行う。 In this apparatus, basically, the level adjustment units 11 to 31 connected to the volume 40 input the value of the volume 40, perform the level adjustment according to the set value set from the memory 43, and perform control to the control target .
　そして、ボリューム４０の値が、ＭＩＮからＭＡＸの間にあるときに、スイッチ４１が切り替わり、ボリューム４０の値を上下して、再度、スイッチ４１が元の接続先に切り替わると、切替前のレベルの値をメモリ４３から読み込み、レベル調整を行うことになる。
　スイッチ４１の切り替えとボリューム４０によるレベル調整の詳細は後述する。 Then, when the value of the volume 40 is between MIN and MAX, the switch 41 is switched to raise or lower the value of the volume 40, and again when the switch 41 is switched to the original connection destination, Values are read from the memory 43 and level adjustment is performed.
Details of the switching of the switch 41 and the level adjustment by the volume 40 will be described later.
［レベル調整部での制御フロー：図２、図３］ 　次に、本装置におけるレベル調整部での制御フローについて図２，３を参照しながら説明する。図２は、本装置におけるレベル調整部での制御フローを示す概略図であり、図３は、特許文献２のレベル調整部での制御フローを示す概略図である。
　本装置の特徴を明確にするために、先に図３の従来技術での制御フローを説明する。 [Control Flow in Level Adjustment Unit: FIGS. 2 and 3] Next, a control flow in the level adjustment unit in the present apparatus will be described with reference to FIGS. FIG. 2 is a schematic view showing a control flow in the level adjustment unit in the present apparatus, and FIG. 3 is a schematic view showing a control flow in the level adjustment unit of Patent Document 2. As shown in FIG.
In order to clarify the features of this device, the control flow in the prior art of FIG. 3 will be described first.
　［従来の制御フロー：図３］ 　図３（ａ）では、例えば、スイッチ４１がボリューム４０をレベル調整部１１に接続している状態での初期状態を示しており、ボリューム４０の目盛とレベルの値は、１：１の状態となっている。 [Conventional Control Flow: FIG. 3] FIG. 3A shows, for example, an initial state in a state where the switch 41 connects the volume 40 to the level adjustment unit 11, and the scale and scale of the volume 40 are shown. The value is 1: 1.
　そして、例えば、ボリューム４０の目盛が「３」でレベルの値「３」の状態で、スイッチ４１がボリーム４０をレベル調整部２１に切り替えたとする。すると、レベル調整部１１はボリューム４０の目盛「３」とレベルの値「３」をメモリ４３に記憶する。
　そして、ボリューム４０の目盛を「８」に上げるよう移動させ、その状態でスイッチ４１が再度レベル調整部１１に接続するよう切り替えたとする。 Then, for example, it is assumed that the switch 41 switches the volume 40 to the level adjustment unit 21 with the scale of the volume 40 being "3" and the level value "3". Then, the level adjustment unit 11 stores the scale “3” of the volume 40 and the value “3” of the level in the memory 43.
Then, it is assumed that the scale of the volume 40 is moved up to “8”, and in this state, the switch 41 is switched to be connected to the level adjustment unit 11 again.
　すると、レベル調整部１１は、メモリ４３から切り替わる前のレベルの値「３」を読み込み、レベル調整を開始する。この場合、ボリューム４０の目盛は「８」に移動しているが、読み出されたレベルの値は「３」であるため、図３（ｂ）に示すような操作点１０２となる。
　操作点は、その時点でのボリューム４０の目盛と実際のレベルとで特定される点である。 Then, the level adjustment unit 11 reads the value “3” of the level before switching from the memory 43 and starts the level adjustment. In this case, although the scale of the volume 40 is moved to “8”, the value of the read level is “3”, so that the operation point 102 as shown in FIG. 3B is obtained.
The operating point is a point specified by the scale of the volume 40 at that time and the actual level.
　図３（ｂ）に示すように、操作点１０２からＭＩＮ（０，０）にレベルを下げる場合は、操作点１０２からＭＩＮ（０，０）を結んだ直線の軌跡上で移動し、操作点１０２からＭＡＸ（１０，１０）にレベルを上げる場合には、操作点１０２からＭＡＸの点を結んだ直線の軌跡上を移動することになる。 As shown in FIG. 3B, when lowering the level from the operating point 102 to MIN (0, 0), the operating point 102 moves on the locus of a straight line connecting MIN (0, 0), and the operating point When raising the level from 102 to MAX (10, 10), it moves on the locus of a straight line connecting the operation point 102 to the point of MAX.
　そして、ボリューム４０の目盛を「８」から「９」に上げた場合を図３（ｃ）に示す。
　つまり、操作点１０２は、ボリューム４０の目盛が「９」となり、そこからボリーム４０を上げる場合はそのままの軌跡上を移動することになるが、ボリーム４０を下げる場合には、図３（ｃ）に示すように、その操作点１０２とＭＩＮ（０，０）とを結んだ直線の軌跡上を移動することになる。
　尚、点線は、操作点が移動した軌道（軌跡）を示し、実線は、操作点がこれから移動する軌道を示している。 The case where the scale of the volume 40 is raised from "8" to "9" is shown in FIG. 3 (c).
That is, in the operation point 102, the scale of the volume 40 is "9", and when raising the volume 40 from that point, it moves on the same trajectory, but when lowering the volume 40, Fig. 3C. As shown in FIG. 2, the movement is made on the locus of a straight line connecting the operation point 102 and MIN (0, 0).
The dotted line indicates the path (locus) along which the operation point has moved, and the solid line indicates the path along which the operation point moves.
　更に、ボリューム４０の目盛を「９」から「３」に下げた状態を図３（ｄ）に示す。
　つまり、操作点１０２は、ボリューム４０の目盛が「３」となり、そこからボリーム４０を下げる場合にはそのままの軌跡上を移動することになるが、ボリーム４０を上げる場合には、図３（ｄ）に示すように、その操作点１０２とＭＡＸ（１０，１０）とを結んだ直線の軌跡上を移動することになる。 Further, a state in which the scale of the volume 40 is lowered from "9" to "3" is shown in FIG. 3 (d).
That is, in the operation point 102, the scale of the volume 40 becomes "3", and when lowering the volume 40 from that point, it moves on the locus as it is, but when raising the volume 40, FIG. As shown in), it moves on the locus of a straight line connecting the operation point 102 and MAX (10, 10).
　そして、ボリューム４０の目盛を「３」から「８．５」に上げた場合を図３（ｅ）に示す。
　つまり、操作点１０２は、ボリューム４０の目盛が「８．５」となり、そこからボリーム４０を上げる場合はそのままの軌跡上を移動することになるが、ボリーム４０を下げる場合には、図３（ｅ）に示すように、その操作点１０２とＭＩＮ（０，０）とを結んだ直線の軌跡上を移動することになる。 The case where the scale of the volume 40 is raised from "3" to "8.5" is shown in FIG.
That is, in the operation point 102, the scale of the volume 40 is "8.5", and when raising the volume 40 from that point, it moves on the same trajectory, but when lowering the volume 40, FIG. As shown in e), it moves on the locus of a straight line connecting the operation point 102 and MIN (0, 0).
　図３に示した特許文献２のレベル調整部における制御フローでは、その軌跡（軌道）は常に現在の操作点１０２と（ボリューム４０の目盛，レベル）＝（０，０）又は（１０，１０）とを接続する２つの直線上となる。 In the control flow in the level adjustment unit of Patent Document 2 shown in FIG. 3, the locus (orbit) thereof is always the current operation point 102 and (scale of volume 40, level) = (0, 0) or (10, 10) And connect two straight lines.
　そのため、上記軌道が、ボリューム４０の目盛：レベルが１：１となる理想の１本の直線上となるには、現在の操作点１０２が（ボリューム４０の目盛、レベル）＝（０，０）又は（１０，１０）に一旦移動する必要があった。
　つまり、ボリューム４０の目盛：レベルを１：１に迅速にするものではなかった。 Therefore, the current operation point 102 (division of volume 40, level) = (0, 0) or It was necessary to move once to 10, 10).
In other words, the scale of the volume 40: the level was not to be quickly made 1: 1.
　［本装置の制御フロー：図２］ 　本装置におけるレベル調整部での制御フローについて図２を参照しながら説明する。
　まず、図２（ａ）に示すように、装置の起動時は初期状態であり、ボリーム４０の目盛とレベルは、１：１の状態となる。 [Control Flow of Present Device: FIG. 2] A control flow of the level adjustment unit in the present device will be described with reference to FIG.
First, as shown in FIG. 2A, when the apparatus is started, it is in the initial state, and the scale and level of the volume 40 are in the state of 1: 1.
　そして、図３（ｂ）と同様に、スイッチ４１が一端切り替わり、更に元の接続先のレベル調整部に切り替わると、切り替わる前のレベルの値をメモリ４３から読み込み、図２（ｂ）に示すように、操作点１０２を設定し、ボリーム４０を上げる場合の軌道と下げる場合の軌道が算出される。 Then, as in FIG. 3B, when the switch 41 is switched at one end and then switched to the original level adjustment unit of the connection destination, the value of the level before switching is read from the memory 43, as shown in FIG. Then, the operating point 102 is set, and the trajectory when raising the volume 40 and the trajectory when lowering it are calculated.
　ここで、本実施の形態の特徴として、中点合致エリア１０１を設けている。
　中点合致エリア１０１とは、予め設定された領域で、図２（ｂ）に示すように、ボリーム４０の「０」～「３」を横方向の幅とし、レベル「０」～「３」を縦方向の幅として形成される第１のエリアと、ボリーム４０の「７」～「１０」を横方向の幅とし、レベル「７」～「１０」を縦方向の幅として形成される第２のエリアとがある。
　中点合致エリア１０１の大きさは任意である。また、中点合致エリア１０１は、初期状態の直線のＭＩＮ側の近辺とＭＡＸ側の近辺に設定するのが望ましいが、初期状態の直線の一方の端部に形成してもよい。 Here, as a feature of the present embodiment, a midpoint matching area 101 is provided.
The middle point matching area 101 is an area set in advance, and as shown in FIG. 2B, with the horizontal width of "0" to "3" of the volume 40, the level "0" to "3" A first area formed with the width in the vertical direction, and “7” to “10” of the volume 40 as the width in the horizontal direction, and a level “7” to “10” formed in the vertical direction There are 2 areas.
The size of the midpoint matching area 101 is arbitrary. In addition, although it is desirable to set the midpoint matching area 101 in the vicinity of the MIN side of the straight line in the initial state and in the vicinity of the MAX side, it may be formed at one end of the straight line in the initial state.
　この中点合致エリア１０１の役割は、ボリーム４０の上げ下げによって操作点１０２が当該中点合致エリア１０１に入った場合に、その後の操作点１０２の移動を、ボリーム４０の目盛：レベルが１：１となる直線（初期状態の直線）の中点１０３を通過させ、その中点１０３を通過した場合には、その後の移動は、初期状態の直線上で為されるように制御するものである。
　ここで、中点とは、図２のＭＩＮ（０，０）とＭＡＸ（１０，１０）を結んだ直線の中点であり、図２では、点（５，５）が中点となる。 The role of the midpoint matching area 101 is to move the manipulation point 102 thereafter when the manipulation point 102 enters the midpoint matching area 101 by raising and lowering the volume 40, the scale of the volume 40 is 1: 1. When passing through the middle point 103 of the straight line (straight line in the initial state) and passing the middle point 103, the subsequent movement is controlled to be performed on the straight line in the initial state.
Here, the middle point is the middle point of the straight line connecting MIN (0, 0) and MAX (10, 10) in FIG. 2, and in FIG. 2 the point (5, 5) is the middle point.
　具体的には、図２（ｃ）に示すように、ボリューム４０の目盛を「８」から「９」に上げた場合は、操作点１０２が中点合致エリア１０１の第２のエリアに入っていない状態で、その操作点１０２からボリーム４０を下げる場合は、操作点１０２とＭＩＮ（０，０）を結んだ直線の軌道上を移動する。 Specifically, as shown in FIG. 2C, when the scale of the volume 40 is raised from “8” to “9”, the operation point 102 is in the second area of the midpoint matching area 101. If the volume 40 is to be lowered from the operating point 102 in the absence state, the robot travels on a straight track connecting the operating point 102 and MIN (0, 0).
　そして、ボリーム４０を下げて行き、中点合致エリア１０１の第１のエリアに入ると、その操作点１０２からボリーム４０を上げる場合には、中点１０３を経由（通過）させる。単に、中点１０３を経由させるのではなく、その中点１０３を通過した後は、更にボリーム４０を上げる場合には、中点１０３とＭＡＸ（１０，１０）を結ぶ直線上を移動する。 Then, when the volume 40 is lowered and the first area of the midpoint matching area 101 is entered, when the volume 40 is to be raised from the operation point 102, the midpoint 103 is passed (passed). When passing through the middle point 103 rather than simply passing through the middle point 103, when raising the volume 40 further, it moves on the straight line connecting the middle point 103 and MAX (10, 10).
　また、中点１０３を通過させた後に、ボリーム４０を下げる場合には、図２（ｄ）に示すように、中点１０３とＭＩＮ（０，０）を結ぶ直線上を移動する。
　つまり、中点１０３を通過させることで、ボリューム４０の目盛：レベルが１：１となる初期状態の直線に迅速かつ簡易に戻すことができるものである。 In addition, when lowering the volume 40 after passing the midpoint 103, as shown in FIG. 2D, it moves on the straight line connecting the midpoint 103 and MIN (0, 0).
That is, by passing the middle point 103, it is possible to quickly and easily return to the initial state straight line where the scale of the volume 40 is 1: 1.
　すなわち、本実施の形態における操作点の動きは以下のようになる。
　中点合致エリア１０１の範囲内に現在の操作点１０２のレベルが入らなければ、その軌道は、常に操作点１０２と（ボリューム目盛，レベル）＝（０，０）又は（１０，１０）を接続する２つの直線上となる。 That is, the movement of the operation point in the present embodiment is as follows.
If the level of the current operating point 102 does not fall within the range of the midpoint matching area 101, its trajectory always connects the operating point 102 with (volume scale, level) = (0, 0) or (10, 10) On two straight lines.
　中点合致エリア１０１の範囲内に現在の操作点１０２のレベルが入ったときは、その軌道は、現在の操作点１０２と（ボリューム目盛，レベル）＝（０，０）又は（１０，１０）の内、現在の操作点１０２から近い方の点を結ぶ直線と、現在の操作点１０２と中点１０３とを結ぶ直線と、中点１０３と（ボリューム目盛，レベル）＝（０，０）又は（１０，１０）の内、現在の操作点１０２から遠い方の点を結ぶ直線の３本の直線上が軌道となる。 When the level of the current operating point 102 falls within the range of the midpoint matching area 101, the trajectory is the current operating point 102 and (volume scale, level) = (0, 0) or (10, 10) Among them, the straight line connecting the point closer to the current operation point 102, the straight line connecting the current operation point 102 and the middle point 103, and the middle point 103 (volume scale, level) = (0, 0) or Of (10, 10), three straight straight lines connecting the points farther from the current operation point 102 are trajectories.
　そして、現在の操作点１０２が中点合致エリア１０１の範囲に入って、制御の中点１０３を通過させることで、ボリューム４０の目盛：レベルが１：１となる直線（初期状態の直線）上に操作点１０２の軌道を迅速かつ容易に戻すものである。
　もしくは、現在の操作点１０２が（ボリューム目盛，レベル）＝（０，０）又は（１０，１０）となることで、初期状態の直線上に操作点１０２の軌道を戻すものである。 Then, the current operation point 102 enters the range of the midpoint matching area 101 and passes the midpoint 103 of control, whereby the scale of the volume 40 is on a straight line (straight line in the initial state) where the level is 1: 1. The trajectory of the operating point 102 is quickly and easily returned.
Alternatively, the trajectory of the operating point 102 is returned to the straight line in the initial state by setting the current operating point 102 to (volume scale, level) = (0, 0) or (10, 10).
［急激なレベル変動の抑制］ 　本装置では、スイッチ４１を切り替えた場合に、予期せぬ急激なレベル変動が発生するのを防止している。本装置での制御手法を説明する前に、特許文献２での制御手法を説明しておく。 [Suppressing Sudden Level Fluctuation] In the present device, when the switch 41 is switched, occurrence of unexpected rapid level fluctuation is prevented. Before describing the control method in this device, the control method in Patent Document 2 will be described.
　［特許文献２の制御手法：図４］ 　まず、特許文献２における制御手法について図４を参照しながら説明する。図４は、特許文献２の制御手法を示す説明図である。
　ボリュームが制御する機能をスイッチ４１が切り替えた際に、ボリュームの目盛が極端に大きい、もしくは小さい位置となり、その逆にレベル（設定値）が極端に小さい、もしくは大きい場合に、ボリュームの目盛の変化量に対してレベルの変動が大きく、ユーザの想定よりも大きな変化を招いてしまうことがある。 [Control Method of Patent Document 2: FIG. 4] First, the control method of Patent Document 2 will be described with reference to FIG. FIG. 4 is an explanatory view showing a control method of Patent Document 2. In FIG.
When switch 41 switches the function to control the volume, the scale of the volume becomes extremely large or small, and conversely, when the level (set value) is extremely small or large, the change of the scale of the volume The variation of the level with respect to the quantity may be large, leading to a change larger than the user's assumption.
　図４では、現在の操作点１０２からボリーム４０の目盛を大きくした場合には、レベルの急激な上昇が発生する例であり、ユーザによっては許容できないものである。 In FIG. 4, when the scale of the volume 40 is increased from the current operation point 102, a sharp rise of the level occurs, which is unacceptable for some users.
［本装置の制御手法：図５］ 　図４に対して、本装置の特徴的な制御手法について図５を参照しながら説明する。図５は、本装置の制御手法を示す説明図である。
　本装置では、図５に示すように、急峻な制御を禁止する急峻制御禁止エリア１０４を設ける。
　急峻制御禁止エリア１０４は、ボリューム目盛「８」～「１０」を横方向の幅とし、レベル「０」～「２」を縦方向の幅として形成される。 [Control Method of Present Device: FIG. 5] A characteristic control method of the present device will be described with reference to FIG. 4 with reference to FIG. FIG. 5 is an explanatory view showing a control method of the present apparatus.
In the present apparatus, as shown in FIG. 5, a steep control prohibition area 104 for prohibiting sharp control is provided.
The steep control prohibition area 104 is formed with the volume scale “8” to “10” as the width in the horizontal direction and the levels “0” to “2” as the width in the vertical direction.
　急峻制御禁止エリア１０４の大きさは任意である。また、急峻制御禁止エリア１０４は、図５の右下に設けたが、左上に設けてもよく、両方に設けてもよい。
　ここで、右下は、ボリーム４０を上げる場合に急峻な変化となるエリアであり、左上は、ボリーム４０を下げる場合に急峻な変化となるエリアである。
　急峻制御禁止エリア１０４と図２の中点合致エリア１０１とを併用して設けてもよい。 The size of the steep control prohibition area 104 is arbitrary. Further, although the steep control prohibition area 104 is provided at the lower right of FIG. 5, it may be provided at the upper left or both.
Here, the lower right is an area where a sharp change occurs when raising the volume 40, and the upper left is an area where a sharp change occurs when lowering the volume 40.
The steep control prohibition area 104 and the midpoint matching area 101 of FIG. 2 may be provided in combination.
　急峻制御禁止エリア１０４における具体的な動作は、スイッチ４１の切り替えによってボリーム４０の機能の変化時に、この急峻制御禁止エリア１０４に現在の操作点１０２が入っている場合に、（ボリューム目盛，レベル）＝（０，０）又は（１０，１０）の内、現在の操作点１０２のレベルと近い方の点と、操作点１０２とを結んだ直線１本のみを軌道として制御を行う。 A specific operation in the steep control prohibition area 104 is (volume scale, level) when the current control point 102 is in the steep control prohibition area 104 when the function of the volume 40 is changed by switching the switch 41. Control is performed with only one straight line connecting the operation point 102 with a point closer to the level of the current operation point 102 out of (0, 0) or (10, 10) as a trajectory.
　図５の例では、現在の操作点１０２とＭＩＮ（０，０）を結んだ直線を延長して、その直線上を軌道とするものである。
　これにより、急激なレベルの上昇又は下降を抑えることができるものである。
　そして、急峻制御禁止エリア１０４の範囲外に出た場合には、図２の制御を行うことになる。 In the example of FIG. 5, the straight line connecting the current operation point 102 and MIN (0, 0) is extended, and the straight line is taken as a trajectory.
As a result, it is possible to suppress a sharp rise or fall of the level.
And when it comes out of the range of the steep control prohibition area 104, control of FIG. 2 will be performed.

［実施の形態の効果］ 　本実施の形態によれば、複数の機能をスイッチ４１で切り替えて機能に応じてレベルを共通のボリューム４０で制御するものであって、スイッチ４１が選択した機能から一旦切り替えられて、切替前の機能を選択すると、メモリ４３に記憶されたレベルを読み込み、当該レベルと現在のボリュームの目盛で特定される点を現在の操作点１０２として、当該操作点１０２と最小点とを結んだ線又は操作点と最大点とを結んだ線の線上を操作点１０２の軌道とし、ボリューム４０の操作で操作点１０２が中点合致エリア１０１に入ると、最小点と最大点とを結ぶ初期状態の線の中点１０３を操作点１０２が通過する軌道とし、操作点１０２が中点１０３を通過すると、初期状態の軌道に戻すようにしているので、機能をスイッチ４１で切り替えた場合に、ボリューム４０とレベルの変化量を迅速に１：１に戻すことができ、違和感なく操作できる効果がある。 [Effects of the Embodiment] According to the present embodiment, a plurality of functions are switched by the switch 41, and the level is controlled by the common volume 40 according to the functions. When the function before switching is selected and the function before switching is selected, the level stored in the memory 43 is read, and the point specified by the level and the scale of the current volume is set as the current operation point 102, the operation point 102 and the minimum point. And the line connecting the operation point and the maximum point is taken as the trajectory of the operation point 102. When the operation point 102 enters the middle point coincident area 101 by the operation of the volume 40, the minimum point and the maximum point Since the middle point 103 of the line in the initial state connecting the points is a trajectory through which the operating point 102 passes, and when the operating point 102 passes the middle point 103, the trajectory of the initial state is restored.
