<Schematic configuration of projection device 10 to which control device of embodiment is applied>
FIG. 1 is a schematic diagram showing a schematic configuration of a projection device 10 to which the control device of the embodiment is applied.
　投影装置１０は、投影部１と、制御装置４と、操作受付部２と、を備える。投影部１は、例えば液晶プロジェクタ又はＬＣＯＳ（Ｌｉｑｕｉｄ　Ｃｒｙｓｔａｌ　Ｏｎ　Ｓｉｌｉｃｏｎ）を用いたプロジェクタ等によって構成される。以下では、投影部１が液晶プロジェクタであるものとして説明する。 The projection device 10 includes a projection section 1 , a control device 4 and an operation reception section 2 . The projection unit 1 is configured by, for example, a liquid crystal projector or a projector using LCOS (Liquid Crystal On Silicon). In the following description, it is assumed that the projection unit 1 is a liquid crystal projector.
　制御装置４は、投影装置１０による投影の制御を行う。また、制御装置４は、本開示の技術に係る１つの実施形態の制御装置の一例である。制御装置４は、各種のプロセッサにより構成される制御部と、各部と通信するための通信インタフェース（図示省略）と、ハードディスク、ＳＳＤ（Ｓｏｌｉｄ　Ｓｔａｔｅ　Ｄｒｉｖｅ）、又はＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）等の記憶媒体４ａと、を含む装置であり、投影部１を統括制御する。制御装置４の制御部の各種のプロセッサとしては、プログラムを実行して各種処理を行う汎用的なプロセッサであるＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）、ＦＰＧＡ（Ｆｉｅｌｄ　Ｐｒｏｇｒａｍｍａｂｌｅ　Ｇａｔｅ　Ａｒｒａｙ）等の製造後に回路構成を変更可能なプロセッサであるプログラマブルロジックデバイス（Ｐｒｏｇｒａｍｍａｂｌｅ　Ｌｏｇｉｃ　Ｄｅｖｉｃｅ：ＰＬＤ）、又はＡＳＩＣ（Ａｐｐｌｉｃａｔｉｏｎ　Ｓｐｅｃｉｆｉｃ　Ｉｎｔｅｇｒａｔｅｄ　Ｃｉｒｃｕｉｔ）等の特定の処理を実行させるために専用に設計された回路構成を有するプロセッサである専用電気回路等が含まれる。 The control device 4 controls projection by the projection device 10 . Also, the control device 4 is an example of a control device of one embodiment according to the technology of the present disclosure. The control device 4 includes a control unit configured by various processors, a communication interface (not shown) for communicating with each unit, and a storage medium such as a hard disk, SSD (Solid State Drive), or ROM (Read Only Memory). 4a, and controls the projection unit 1 in an integrated manner. As various processors of the control unit of the control device 4, the circuit configuration is changed after manufacturing such as CPU (Central Processing Unit), FPGA (Field Programmable Gate Array), which is a general-purpose processor that executes programs and performs various processes. Programmable Logic Device (PLD), which is a processor, or a dedicated electric circuit, etc., which is a processor having a circuit configuration specially designed to execute specific processing such as ASIC (Application Specific Integrated Circuit) is included.
　これら各種のプロセッサの構造は、より具体的には、半導体素子等の回路素子を組み合わせた電気回路である。制御装置４の制御部は、各種のプロセッサのうちの１つで構成されてもよいし、同種又は異種の２つ以上のプロセッサの組み合わせ（例えば、複数のＦＰＧＡの組み合わせ又はＣＰＵとＦＰＧＡの組み合わせ）で構成されてもよい。 More specifically, the structures of these various processors are electric circuits that combine circuit elements such as semiconductor elements. The control unit of the control device 4 may be composed of one of various processors, or a combination of two or more processors of the same type or different types (for example, a combination of multiple FPGAs or a combination of a CPU and an FPGA). may consist of
　操作受付部２は、ユーザからの各種の操作を受け付けることにより、ユーザからの指示（ユーザ指示）を検出する。本形態において、操作受付部２は、投影装置１０の本体に設けられたボタン、キー、ジョイスティック等の操作部である。したがって、操作受付部２が操作された場合、ユーザが投影装置１０の付近に位置していると判定可能である。 The operation reception unit 2 detects instructions from the user (user instructions) by receiving various operations from the user. In this embodiment, the operation reception unit 2 is an operation unit such as buttons, keys, and joysticks provided on the main body of the projection device 10 . Therefore, when the operation reception unit 2 is operated, it can be determined that the user is positioned near the projection device 10 .
　第１投影領域６ａは、投影部１によって投影画像が表示される投影面を有するスクリーンなどの物体である。図１に示す例では、第１投影領域６ａは、第１投影領域６ａの投影面は矩形の平面である。図１における第１投影領域６ａの上下左右が、実際の第１投影領域６ａの上下左右であるとする。 The first projection area 6a is an object such as a screen having a projection surface on which a projection image is displayed by the projection unit 1. In the example shown in FIG. 1, the projection plane of the first projection area 6a is a rectangular plane. Assume that the top, bottom, left, and right of the first projection area 6a in FIG. 1 are the actual top, bottom, left, and right of the first projection area 6a.
　第２投影領域６ｂは、第１投影領域６ａに対して可動な投影領域である。第２投影領域６ｂは、第１投影領域６ａより小さく、第１投影領域６ａと投影装置１０との間に配置されている。図１に示す例では、第２投影領域６ｂは球体である。 The second projection area 6b is a projection area movable with respect to the first projection area 6a. The second projection area 6 b is smaller than the first projection area 6 a and is arranged between the first projection area 6 a and the projection device 10 . In the example shown in FIG. 1, the second projection area 6b is a sphere.
　例えば、第１投影領域６ａと投影装置１０との間には、レールが設けられており、第２投影領域６ｂはこのレール上を移動可能である。又は、第２投影領域６ｂは、遠隔操作等によって転がることにより移動可能であってもよい。第２投影領域６ｂの移動方法は、これに限らず各種の方法とすることができる。 For example, a rail is provided between the first projection area 6a and the projection device 10, and the second projection area 6b can move on this rail. Alternatively, the second projection area 6b may be movable by rolling by remote control or the like. The method of moving the second projection area 6b is not limited to this, and various methods can be used.
　第２投影領域６ｂの移動は、例えば制御装置４によって制御される。ただし、第２投影領域６ｂの移動は制御装置４とは異なる装置により制御されてもよいし、人間が手で押すなどして第２投影領域６ｂを移動させてもよい。 The movement of the second projection area 6b is controlled by the control device 4, for example. However, the movement of the second projection area 6b may be controlled by a device different from the control device 4, or may be manually pushed by a person to move the second projection area 6b.
　一点鎖線で図示する投影範囲１１は、投影部１により投影光が照射される領域である。投影範囲１１は、投影部１により投影が可能な投影範囲の一部又は全部であり、所定品質を保って投影可能な範囲である。第１投影領域６ａ及び第２投影領域６ｂにおける投影装置１０の側の表面のうち、投影範囲１１に含まれる領域に画像が投影されることになる。 A projection range 11 indicated by a dashed line is an area where the projection unit 1 irradiates the projection light. The projection range 11 is part or all of the projection range that can be projected by the projection unit 1, and is the range that can be projected while maintaining a predetermined quality. An image is projected onto a region included in the projection range 11 among the surfaces of the projection device 10 side in the first projection region 6a and the second projection region 6b.
　なお、投影部１、制御装置４、及び操作受付部２は、例えば一個の装置により実現される（例えば図３，図４参照）。又は、投影部１、制御装置４、及び操作受付部２は、互いに通信を行うことにより連携する、それぞれ別の装置であってもよい。 Note that the projection unit 1, the control device 4, and the operation reception unit 2 are realized by, for example, one device (see FIGS. 3 and 4, for example). Alternatively, the projection unit 1, the control device 4, and the operation reception unit 2 may be separate devices that cooperate by communicating with each other.
＜図１に示す投影部１の内部構成＞
　図２は、図１に示す投影部１の内部構成の一例を示す模式図である。 <Internal Configuration of Projector 1 Shown in FIG. 1>
FIG. 2 is a schematic diagram showing an example of the internal configuration of the projection unit 1 shown in FIG.
　図２に示すように、投影部１は、光源２１と、光変調部２２と、投影光学系２３と、制御回路２４と、を備える。 As shown in FIG. 2, the projection unit 1 includes a light source 21, a light modulation unit 22, a projection optical system 23, and a control circuit 24.
　光源２１は、レーザ又はＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）等の発光素子を含み、例えば白色光を出射する。 The light source 21 includes a light-emitting element such as a laser or LED (Light Emitting Diode), and emits white light, for example.
　光変調部２２は、光源２１から出射されて図示省略の色分離機構によって赤、青、緑の３色に分離された各色光を、画像情報に基づいて変調して各色画像を出射する３つの液晶パネルによって構成される光変調素子である。この３つの液晶パネルにそれぞれ赤、青、緑のフィルタを搭載し、光源２１から出射された白色光を、各液晶パネルにて変調して各色画像を出射させてもよい。 The light modulation unit 22 modulates each color light emitted from the light source 21 and separated into three colors of red, blue, and green by a color separation mechanism (not shown) based on image information, and outputs each color image. It is a light modulation element composed of a liquid crystal panel. Red, blue, and green filters may be mounted on these three liquid crystal panels, respectively, and the white light emitted from the light source 21 may be modulated by each liquid crystal panel to emit an image of each color.
　投影光学系２３は、光源２１及び光変調部２２からの光が入射されるものであり、少なくとも１つのレンズを含む、例えばリレー光学系によって構成されている。投影光学系２３を通過した光は第１投影領域６ａ及び第２投影領域６ｂに投影される。 The projection optical system 23 receives the light from the light source 21 and the light modulation section 22, and includes at least one lens and is configured by, for example, a relay optical system. The light passing through the projection optical system 23 is projected onto the first projection area 6a and the second projection area 6b.
　第１投影領域６ａ及び第２投影領域６ｂのうち、光変調部２２の全範囲を透過する光が照射される領域が、投影部１により投影が可能な投影範囲となる。この投影範囲のうち、光変調部２２から実際に透過する光が照射される領域が投影範囲１１となる。例えば、光変調部２２のうち光が透過する領域の大きさ、位置、及び形状を制御することにより、投影範囲において、投影範囲１１の大きさ、位置、及び形状が変化する。 Of the first projection area 6a and the second projection area 6b, the area irradiated with the light that passes through the entire range of the light modulation section 22 is the projection range in which the projection section 1 can project. Of this projection range, the projection range 11 is a region irradiated with the light that is actually transmitted from the light modulation section 22 . For example, by controlling the size, position, and shape of the light-transmitting region of the light modulation section 22, the size, position, and shape of the projection range 11 change in the projection range.
　制御回路２４は、制御装置４から入力される表示用データに基づいて、光源２１、光変調部２２、及び投影光学系２３を制御することにより、第１投影領域６ａ及び第２投影領域６ｂにこの表示用データに基づく画像を投影させる。制御回路２４に入力される表示用データは、赤表示用データと、青表示用データと、緑表示用データとの３つによって構成される。 The control circuit 24 controls the light source 21, the light modulation unit 22, and the projection optical system 23 based on the display data input from the control device 4, thereby displaying the first projection area 6a and the second projection area 6b. An image based on this display data is projected. The display data to be input to the control circuit 24 is composed of red display data, blue display data, and green display data.
　また、制御回路２４は、制御装置４から入力される命令に基づいて、投影光学系２３を変化させることにより、投影部１の投影範囲１１（図１参照）の拡大や縮小を行う。また、制御装置４は、操作受付部２によって受け付けられたユーザからの操作に基づいて投影光学系２３を変化させることにより、投影部１の投影範囲１１の移動を行ってもよい。 Also, the control circuit 24 enlarges or reduces the projection range 11 (see FIG. 1) of the projection unit 1 by changing the projection optical system 23 based on commands input from the control device 4 . Further, the control device 4 may move the projection range 11 of the projection unit 1 by changing the projection optical system 23 based on the user's operation received by the operation reception unit 2 .
　また、投影装置１０は、投影光学系２３のイメージサークルを維持しつつ、投影範囲１１を機械的又は光学的に移動させるシフト機構を備える。投影光学系２３のイメージサークルは、投影光学系２３に入射した投影光が、光量落ち、色分離、周辺湾曲などの点から適正に投影光学系２３を通過する領域である。 The projection device 10 also includes a shift mechanism that mechanically or optically moves the projection range 11 while maintaining the image circle of the projection optical system 23 . The image circle of the projection optical system 23 is an area in which the projection light incident on the projection optical system 23 passes through the projection optical system 23 appropriately in terms of light falloff, color separation, peripheral curvature, and the like.
　シフト機構は、光学系シフトを行う光学系シフト機構と、電子シフトを行う電子シフト機構と、の少なくともいずれかにより実現される。 The shift mechanism is realized by at least one of an optical system shift mechanism that performs optical system shift and an electronic shift mechanism that performs electronic shift.
　光学系シフト機構は、例えば、投影光学系２３を光軸に垂直な方向に移動させる機構（例えば図３，図４参照）、又は、投影光学系２３を移動させる代わりに光変調部２２を光軸に垂直な方向に移動させる機構である。また、光学系シフト機構は、投影光学系２３の移動と光変調部２２の移動とを組み合わせて行うものであってもよい。 The optical system shift mechanism is, for example, a mechanism that moves the projection optical system 23 in a direction perpendicular to the optical axis (see, for example, FIGS. 3 and 4), or a mechanism that shifts the light modulation section 22 instead of moving the projection optical system 23. It is a mechanism that moves in the direction perpendicular to the axis. Further, the optical system shift mechanism may combine the movement of the projection optical system 23 and the movement of the light modulation section 22 .
　電子シフト機構は、光変調部２２において光を透過させる範囲を変化させることによる疑似的な投影範囲１１のシフトを行う機構である。 The electronic shift mechanism is a mechanism that shifts the pseudo projection range 11 by changing the light transmission range in the light modulation section 22 .
　また、投影装置１０は、投影光学系２３のイメージサークルとともに投影範囲１１を移動させる投影方向変更機構を備えてもよい。投影方向変更機構は、機械的な回転で投影部１の向きを変更することにより、投影部１の投影方向を変化させる機構である（例えば図３，図４参照）。 The projection device 10 may also include a projection direction changing mechanism that moves the projection range 11 together with the image circle of the projection optical system 23 . The projection direction changing mechanism is a mechanism that changes the projection direction of the projection unit 1 by changing the orientation of the projection unit 1 by mechanical rotation (see FIGS. 3 and 4, for example).

　本体部１０１は、光学ユニット１０６と連結される部分に光を通すための開口１５ａ（図４参照）が形成された筐体１５（図４参照）を有する。 The body part 101 has a housing 15 (see FIG. 4) in which an opening 15a (see FIG. 4) for passing light is formed in a portion connected to the optical unit 106.
　本体部１０１の筐体１５の内部には、図３に示すように、光源２１と、光源２１から出射される光を入力画像データに基づいて空間変調して画像を生成する光変調部２２（図２参照）を含む光変調ユニット１２と、が設けられている。 Inside the housing 15 of the main unit 101, as shown in FIG. 3, there are a light source 21 and a light modulation unit 22 ( (see FIG. 2) is provided.
　光源２１から出射された光は、光変調ユニット１２の光変調部２２に入射され、光変調部２２によって空間変調されて出射される。 The light emitted from the light source 21 enters the light modulating section 22 of the light modulating unit 12, is spatially modulated by the light modulating section 22, and is emitted.
　図４に示すように、光変調ユニット１２によって空間変調された光によって形成される画像は、筐体１５の開口１５ａを通過して光学ユニット１０６に入射され、投影対象物としての第１投影領域６ａ及び第２投影領域６ｂに投影されて、画像Ｇ１，Ｇ２が観察者から視認可能となる。画像Ｇ１は、第１投影領域６ａに投影される画像であり、画像ＧＧ２は第２投影領域６ｂに投影される画像である。 As shown in FIG. 4, an image formed by light spatially modulated by the light modulation unit 12 passes through the opening 15a of the housing 15 and is incident on the optical unit 106, whereupon the first projection region as the projection target is projected. Images G1 and G2 are projected onto 6a and the second projection area 6b, and the images G1 and G2 become visible to the observer. The image G1 is an image projected onto the first projection area 6a, and the image GG2 is an image projected onto the second projection area 6b.
　図４に示すように、光学ユニット１０６は、本体部１０１の内部と繋がる中空部２Ａを有する第一部材１０２と、中空部２Ａと繋がる中空部３Ａを有する第二部材１０３と、中空部２Ａに配置された第一光学系１２１及び反射部材１２２と、中空部３Ａに配置された第二光学系３１、反射部材３２、第三光学系３３、及びレンズ３４と、シフト機構１０５と、投影方向変更機構１０４と、を備える。 As shown in FIG. 4, the optical unit 106 includes a first member 102 having a hollow portion 2A connected to the inside of the main body portion 101, a second member 103 having a hollow portion 3A connected to the hollow portion 2A, and The first optical system 121 and the reflecting member 122 arranged, the second optical system 31, the reflecting member 32, the third optical system 33, and the lens 34 arranged in the hollow portion 3A, the shift mechanism 105, and the projection direction change and a mechanism 104 .
　第一部材１０２は、断面外形が一例として矩形の部材であり、開口２ａと開口２ｂが互いに垂直な面に形成されている。第一部材１０２は、本体部１０１の開口１５ａと対面する位置に開口２ａが配置される状態にて、本体部１０１によって支持されている。本体部１０１の光変調ユニット１２の光変調部２２から射出された光は、開口１５ａ及び開口２ａを通って第一部材１０２の中空部２Ａに入射される。 The first member 102 is, for example, a member having a rectangular cross-sectional outline, and the openings 2a and 2b are formed on surfaces perpendicular to each other. The first member 102 is supported by the body portion 101 with the opening 2a arranged at a position facing the opening 15a of the body portion 101 . Light emitted from the light modulating portion 22 of the light modulating unit 12 of the main body portion 101 enters the hollow portion 2A of the first member 102 through the openings 15a and 2a.
　本体部１０１から中空部２Ａに入射される光の入射方向を方向Ｘ１と記載し、方向Ｘ１の逆方向を方向Ｘ２と記載し、方向Ｘ１と方向Ｘ２を総称して方向Ｘと記載する。また、図４において、紙面手前から奥に向かう方向とその逆方向を方向Ｚと記載する。方向Ｚのうち、紙面手前から奥に向かう方向を方向Ｚ１と記載し、紙面奥から手前に向かう方向を方向Ｚ２と記載する。 The incident direction of light entering the hollow portion 2A from the main body portion 101 is described as the direction X1, the direction opposite to the direction X1 is described as the direction X2, and the directions X1 and X2 are collectively described as the direction X. In addition, in FIG. 4, the direction from the front to the back of the paper surface and the opposite direction are described as a direction Z. As shown in FIG. Of the directions Z, the direction from the front to the back of the paper is described as a direction Z1, and the direction from the back to the front of the paper is described as a direction Z2.
　また、方向Ｘ及び方向Ｚに垂直な方向を方向Ｙと記載し、方向Ｙのうち、図４において上に向かう方向を方向Ｙ１と記載し、図４において下に向かう方向を方向Ｙ２と記載する。図４の例では方向Ｙ２が鉛直方向となるように投影装置１０が配置されている。 A direction perpendicular to the direction X and the direction Z is described as a direction Y, of the directions Y, the upward direction in FIG. 4 is described as a direction Y1, and the downward direction in FIG. 4 is described as a direction Y2. . In the example of FIG. 4, the projection device 10 is arranged so that the direction Y2 is the vertical direction.
　図２に示した投影光学系２３は、第一光学系１２１、反射部材１２２、第二光学系３１、反射部材３２、第三光学系３３、及びレンズ３４により構成される。図４には、この投影光学系２３の光軸Ｋが示されている。第一光学系１２１、反射部材１２２、第二光学系３１、反射部材３２、第三光学系３３、及びレンズ３４は、光変調部２２側からこの順に光軸Ｋに沿って配置されている。 The projection optical system 23 shown in FIG. 2 is composed of a first optical system 121, a reflecting member 122, a second optical system 31, a reflecting member 32, a third optical system 33, and a lens . The optical axis K of this projection optical system 23 is shown in FIG. The first optical system 121, the reflecting member 122, the second optical system 31, the reflecting member 32, the third optical system 33, and the lens 34 are arranged along the optical axis K in this order from the light modulation section 22 side.
　第一光学系１２１は、少なくとも１つのレンズを含み、本体部１０１から第一部材１０２に入射された方向Ｘ１に進む光を反射部材１２２に導く。 The first optical system 121 includes at least one lens, and guides the light that has entered the first member 102 from the main body 101 and travels in the direction X1 to the reflecting member 122 .
　反射部材１２２は、第一光学系１２１から入射された光を方向Ｙ１に反射させる。反射部材１２２は、例えばミラー等によって構成される。第一部材１０２には、反射部材１２２にて反射した光の光路上に開口２ｂが形成されており、この反射した光は開口２ｂを通過して第二部材１０３の中空部３Ａへと進む。 The reflecting member 122 reflects the light incident from the first optical system 121 in the direction Y1. The reflecting member 122 is composed of, for example, a mirror. The first member 102 has an opening 2b on the optical path of the light reflected by the reflecting member 122, and the reflected light passes through the opening 2b and advances to the hollow portion 3A of the second member 103.
　第二部材１０３は、断面外形が略Ｔ字状の部材であり、第一部材１０２の開口２ｂと対面する位置に開口３ａが形成されている。第一部材１０２の開口２ｂを通過した本体部１０１からの光は、この開口３ａを通って第二部材１０３の中空部３Ａに入射される。なお、第一部材１０２や第二部材１０３の断面外形は任意であり、上記のものには限定されない。 The second member 103 is a member having a substantially T-shaped cross-sectional outline, and an opening 3a is formed at a position facing the opening 2b of the first member 102. The light from the body portion 101 that has passed through the opening 2b of the first member 102 enters the hollow portion 3A of the second member 103 through this opening 3a. Note that the cross-sectional outlines of the first member 102 and the second member 103 are arbitrary, and are not limited to those described above.
　第二光学系３１は、少なくとも１つのレンズを含み、第一部材１０２から入射された光を、反射部材３２に導く。 The second optical system 31 includes at least one lens and guides light incident from the first member 102 to the reflecting member 32 .
　反射部材３２は、第二光学系３１から入射される光を方向Ｘ２に反射させて第三光学系３３に導く。反射部材３２は、例えばミラー等によって構成される。 The reflecting member 32 reflects the light incident from the second optical system 31 in the direction X2 and guides it to the third optical system 33 . The reflecting member 32 is composed of, for example, a mirror.
　第三光学系３３は、少なくとも１つのレンズを含み、反射部材３２にて反射された光をレンズ３４に導く。 The third optical system 33 includes at least one lens and guides the light reflected by the reflecting member 32 to the lens 34.
　レンズ３４は、第二部材１０３の方向Ｘ２側の端部に形成された開口３ｃを塞ぐ形でこの端部に配置されている。レンズ３４は、第三光学系３３から入射された光を第１投影領域６ａ及び第２投影領域６ｂに投影する。 The lens 34 is arranged at the end of the second member 103 so as to block the opening 3c formed at the end of the second member 103 on the direction X2 side. The lens 34 projects the light incident from the third optical system 33 onto the first projection area 6a and the second projection area 6b.
　投影方向変更機構１０４は、第一部材１０２に対して第二部材１０３を回転自在に連結する回転機構である。この投影方向変更機構１０４によって、第二部材１０３は、方向Ｙに延びる回転軸（具体的には光軸Ｋ）の回りに回転自在に構成されている。なお、投影方向変更機構１０４は、光学系を回転させることができればよく、図４に示した配置位置に限定されない。また、回転機構の数も１つに限らず、複数設けられていてもよい。 The projection direction changing mechanism 104 is a rotating mechanism that rotatably connects the second member 103 to the first member 102 . The projection direction changing mechanism 104 allows the second member 103 to rotate about a rotation axis extending in the direction Y (specifically, the optical axis K). Note that the projection direction changing mechanism 104 is not limited to the arrangement position shown in FIG. 4 as long as it can rotate the optical system. Also, the number of rotating mechanisms is not limited to one, and a plurality of rotating mechanisms may be provided.
　シフト機構１０５は、投影光学系の光軸Ｋ（換言すると光学ユニット１０６）をその光軸Ｋに垂直な方向（図４の方向Ｙ）に移動させるための機構である。具体的には、シフト機構１０５は、第一部材１０２の本体部１０１に対する方向Ｙの位置を変更することができるように構成されている。シフト機構１０５は、手動にて第一部材１０２を移動させるものの他、電動にて第一部材１０２を移動させるものであってもよい。 The shift mechanism 105 is a mechanism for moving the optical axis K of the projection optical system (in other words, the optical unit 106) in a direction perpendicular to the optical axis K (direction Y in FIG. 4). Specifically, the shift mechanism 105 is configured to change the position of the first member 102 in the direction Y with respect to the body portion 101 . The shift mechanism 105 may be one that moves the first member 102 manually, or one that moves the first member 102 electrically.
　図４は、シフト機構１０５によって第一部材１０２が方向Ｙ１側に最大限移動された状態を示している。この図４に示す状態から、シフト機構１０５によって第一部材１０２が方向Ｙ２に移動することで、光変調部２２によって形成される画像の中心（換言すると表示面の中心）と光軸Ｋとの相対位置が変化して、第１投影領域６ａ及び第２投影領域６ｂに投影されている画像Ｇ１，Ｇ２を方向Ｙ２にシフト（平行移動）させることができる。 FIG. 4 shows a state in which the shift mechanism 105 has moved the first member 102 to the maximum extent in the direction Y1. Shift mechanism 105 moves first member 102 in direction Y2 from the state shown in FIG. The images G1 and G2 projected on the first projection area 6a and the second projection area 6b can be shifted (translated) in the direction Y2 by changing the relative positions.
　なお、シフト機構１０５は、光学ユニット１０６を方向Ｙに移動させる代わりに、光変調部２２を方向Ｙに移動させる機構であってもよい。この場合でも、第１投影領域６ａ及び第２投影領域６ｂに投影されている画像Ｇ１，Ｇ２を方向Ｙ２に移動させることができる。 Note that the shift mechanism 105 may be a mechanism that moves the light modulation section 22 in the Y direction instead of moving the optical unit 106 in the Y direction. Even in this case, the images G1 and G2 projected onto the first projection area 6a and the second projection area 6b can be moved in the direction Y2.
＜第２投影領域６ｂの移動＞
　図５～図７は、投影方向における第２投影領域６ｂの移動の一例を示す図である。第２投影領域６ｂは、投影装置１０と第１投影領域６ａとの間で、少なくとも投影装置１０の投影方向（例えば光軸Ｋの方向）に、すなわち投影装置１０との距離が変化するように移動可能である。第２距離Ｚａは、投影装置１０と第１投影領域６ａとの間の距離である。第１距離Ｚｂは、投影装置１０と第２投影領域６ｂとの間の距離である。この例では、投影装置１０及び第１投影領域６ａの位置が固定であり、第２投影領域６ｂが移動可能であることにより、第２距離Ｚａは固定であり、第１距離Ｚｂは可変である。 <Movement of second projection area 6b>
5 to 7 are diagrams showing an example of movement of the second projection area 6b in the projection direction. The second projection region 6b is formed between the projection device 10 and the first projection region 6a at least in the projection direction of the projection device 10 (for example, the direction of the optical axis K), that is, so that the distance from the projection device 10 changes. It is movable. The second distance Za is the distance between the projection device 10 and the first projection area 6a. The first distance Zb is the distance between the projection device 10 and the second projection area 6b. In this example, the positions of the projection device 10 and the first projection area 6a are fixed, and the second projection area 6b is movable, so that the second distance Za is fixed and the first distance Zb is variable. .
　図５は、第２投影領域６ｂが投影装置１０から比較的遠い、すなわち第１距離Ｚｂが比較的長い状態を示している。図７は、第２投影領域６ｂが投影装置１０に比較的近い、すなわち第１距離Ｚｂが比較的短い状態を示している。図６は、第２投影領域６ｂの位置が図５，図７の各位置の中間付近である、すなわち第１距離Ｚｂが中程度である状態を示している。 FIG. 5 shows a state where the second projection area 6b is relatively far from the projection device 10, that is, the first distance Zb is relatively long. FIG. 7 shows a state where the second projection area 6b is relatively close to the projection device 10, ie the first distance Zb is relatively short. FIG. 6 shows a state where the position of the second projection area 6b is near the middle of each position shown in FIGS. 5 and 7, that is, the first distance Zb is intermediate.
　制御装置４は、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂを特定する。例えば、第２投影領域６ｂの移動が制御装置４の制御によって行われる場合は、制御装置４は第２投影領域６ｂの移動の制御結果に基づいて第１距離Ｚｂを特定する。また、第２投影領域６ｂの移動が制御装置４とは別の装置の制御によって行われる場合は、制御装置４は、その別の装置から第２投影領域６ｂの移動の制御結果を受信することにより第１距離Ｚｂを特定する。 The control device 4 specifies the first distance Zb between the projection device 10 and the second projection area 6b. For example, when the movement of the second projection area 6b is controlled by the control device 4, the control device 4 specifies the first distance Zb based on the control result of the movement of the second projection area 6b. In addition, when the movement of the second projection area 6b is performed by the control of a device other than the control device 4, the control device 4 receives the control result of the movement of the second projection region 6b from the other device. specifies the first distance Zb.
　また、制御装置４は、投影装置１０と第２投影領域６ｂとの間の距離を測定可能な測距装置から測距結果を受信することにより第１距離Ｚｂを特定してもよい。測距装置は、投影装置１０に設けられていてもよいし、投影装置１０と通信可能な他の装置に設けられていてもよい。また、制御装置４は、操作受付部２を介してユーザから第１距離Ｚｂの入力を受け付けることにより第１距離Ｚｂを特定してもよい。 Also, the control device 4 may specify the first distance Zb by receiving a distance measurement result from a distance measurement device capable of measuring the distance between the projection device 10 and the second projection area 6b. The distance measuring device may be provided in the projection device 10 or may be provided in another device capable of communicating with the projection device 10 . Further, the control device 4 may specify the first distance Zb by accepting input of the first distance Zb from the user via the operation accepting unit 2 .
＜投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂに応じた画像加工＞
　図８～図１０は、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂに応じた画像加工の一例を示す図である。制御装置４は、例えば、背景コンテンツに対して可動コンテンツを重ね合わせて生成した画像を光変調部２２へ入力することにより、第１投影領域６ａに背景コンテンツを投影しつつ、第２投影領域６ｂに可動コンテンツを投影する制御を行う。背景コンテンツは、背景画像であり、この例では雲を含む空の画像である。可動コンテンツは、背景画像の前面に重ね合わされる主題画像であり、この例では人物の顔の画像である。 <Image processing according to first distance Zb between projection device 10 and second projection area 6b>
8 to 10 are diagrams showing an example of image processing according to the first distance Zb between the projection device 10 and the second projection area 6b. For example, by inputting an image generated by superimposing the movable content on the background content to the light modulation unit 22, the control device 4 projects the background content on the first projection region 6a while projecting the background content on the second projection region 6b. control the projection of movable content on The background content is a background image, in this example an image of the sky with clouds. The movable content is a thematic image that is superimposed in front of the background image, in this example an image of a person's face.
　図８は、図５に示した状態（第１距離Ｚｂが比較的長い状態）における投影装置１０による投影を示している。画像６１は、図８の例において制御装置４の制御によって光変調部２２へ入力される画像である。図８の例においては、投影装置１０から見て、投影範囲１１における第２投影領域６ｂが占める部分の割合は比較的小さい。このため、制御装置４は、第２投影領域６ｂの範囲に合わせて可動コンテンツが投影されるように、比較的小さいサイズに調整した可動コンテンツを背景コンテンツに重ね合わせて生成した画像６１を光変調部２２へ入力する制御を行う。 FIG. 8 shows projection by the projection device 10 in the state shown in FIG. 5 (where the first distance Zb is relatively long). An image 61 is an image input to the light modulation section 22 under the control of the control device 4 in the example of FIG. In the example of FIG. 8, the ratio of the portion occupied by the second projection area 6b in the projection range 11 is relatively small when viewed from the projection device 10. In the example of FIG. Therefore, the control device 4 optically modulates an image 61 generated by superimposing the movable content adjusted to a relatively small size on the background content so that the movable content is projected according to the range of the second projection area 6b. It controls the input to the unit 22 .
　また、第１距離Ｚｂが比較的長い状態においては、投射光の減衰等によって、第２投影領域６ｂに投影される投影画像が比較的暗くなる。このため、制御装置４は、図８の例においては、背景コンテンツに重ね合わせる可動コンテンツの輝度を比較的高くする（輝度：高）。可動コンテンツの輝度の調整は、例えば背景コンテンツに重ね合わせる可動コンテンツに対してゲインをかけることにより行うことができる。 Also, when the first distance Zb is relatively long, the projection image projected onto the second projection area 6b becomes relatively dark due to attenuation of the projection light or the like. Therefore, in the example of FIG. 8, the control device 4 relatively increases the brightness of the movable content to be superimposed on the background content (brightness: high). Adjustment of the brightness of the movable content can be performed, for example, by applying a gain to the movable content superimposed on the background content.
　図９は、図６に示した状態（第１距離Ｚｂが中程度である状態）における投影装置１０による投影を示している。画像６２は、図９の例において制御装置４の制御によって光変調部２２へ入力される画像である。図９の例においては、投影装置１０から見て、投影範囲１１における第２投影領域６ｂが占める部分の割合が中程度である。このため、制御装置４は、第２投影領域６ｂの範囲に合わせて可動コンテンツが投影されるように、中程度のサイズに調整した可動コンテンツを背景コンテンツに重ね合わせて生成した画像６２を光変調部２２へ入力する制御を行う。 FIG. 9 shows projection by the projection device 10 in the state shown in FIG. 6 (the state where the first distance Zb is medium). An image 62 is an image that is input to the light modulation section 22 under the control of the control device 4 in the example of FIG. In the example of FIG. 9, as viewed from the projection device 10, the ratio of the portion occupied by the second projection area 6b in the projection range 11 is medium. Therefore, the control device 4 optically modulates an image 62 generated by superimposing the movable content adjusted to a medium size on the background content so that the movable content is projected according to the range of the second projection area 6b. It controls the input to the unit 22 .
　また、第１距離Ｚｂが中程度である状態においては、第２投影領域６ｂに投影される投影画像の明るさも中程度となる。このため、制御装置４は、図９の例においては、背景コンテンツに重ね合わせる可動コンテンツの輝度を中程度にする（輝度：中）。 Also, in a state where the first distance Zb is intermediate, the brightness of the projected image projected onto the second projection area 6b is also intermediate. Therefore, in the example of FIG. 9, the control device 4 sets the brightness of the movable content to be superimposed on the background content to medium (brightness: medium).
　図１０は、図７に示した状態（第１距離Ｚｂが比較的短い状態）における投影装置１０による投影を示している。画像６３は、図１０の例において制御装置４の制御によって光変調部２２へ入力される画像である。図１０の例においては、投影装置１０から見て、投影範囲１１における第２投影領域６ｂが占める部分の割合は比較的大きい。このため、制御装置４は、第２投影領域６ｂの範囲に合わせて可動コンテンツが投影されるように、比較的大きいサイズに調整した可動コンテンツを背景コンテンツに重ね合わせて生成した画像６３を光変調部２２へ入力する制御を行う。 FIG. 10 shows projection by the projection device 10 in the state shown in FIG. 7 (where the first distance Zb is relatively short). An image 63 is an image input to the light modulating section 22 under the control of the control device 4 in the example of FIG. In the example of FIG. 10, the ratio of the portion occupied by the second projection area 6b in the projection range 11 is relatively large when viewed from the projection device 10. In the example of FIG. Therefore, the control device 4 optically modulates an image 63 generated by superimposing the movable content adjusted to a relatively large size on the background content so that the movable content is projected according to the range of the second projection area 6b. It controls the input to the unit 22 .
　また、第１距離Ｚｂが比較的短い状態においては、投射光の減衰等が少なく、第２投影領域６ｂに投影される投影画像が比較的明るくなる。このため、制御装置４は、図１０の例においては、背景コンテンツに重ね合わせる可動コンテンツの輝度を比較的低くする（輝度：低）。 In addition, when the first distance Zb is relatively short, the projection light is less attenuated and the projection image projected onto the second projection area 6b is relatively bright. Therefore, in the example of FIG. 10, the control device 4 relatively lowers the brightness of the movable content superimposed on the background content (brightness: low).
　図５～図１０に示したように、制御装置４は、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂに応じて、投影装置１０が投影対象への投影に用いる画像データのうち第２投影領域６ｂに投影される可動コンテンツに対してサイズを変更する加工処理を行う制御を実行する。 As shown in FIGS. 5 to 10, the control device 4 controls the image data used by the projection device 10 for projection onto the projection target according to the first distance Zb between the projection device 10 and the second projection area 6b. Control is executed to perform processing processing for changing the size of the movable content projected onto the second projection area 6b.
　これにより、投影装置１０との間の距離が固定である第１投影領域６ａに投影される背景コンテンツのサイズは維持しつつ、投影装置１０との間の距離が可変である第２投影領域６ｂに投影される可動コンテンツのサイズを第２投影領域６ｂに合わせて調整することができる。このため、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂの変化があっても、第１投影領域６ａに背景コンテンツを投影し第２投影領域６ｂに可動コンテンツを投影する状態を維持し、投影品質を向上させることができる。 As a result, while maintaining the size of the background content projected onto the first projection area 6a whose distance from the projection apparatus 10 is fixed, the second projection area 6b whose distance from the projection apparatus 10 is variable It is possible to adjust the size of the movable content projected onto the second projection area 6b. Therefore, even if the first distance Zb between the projection device 10 and the second projection area 6b changes, the background content is projected on the first projection area 6a and the movable content is projected on the second projection area 6b. can be maintained and the projection quality can be improved.
　例えば、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂの増加時に、第２投影領域６ｂに投影される可動コンテンツが第２投影領域６ｂに対して不自然に大きくなったり、可動コンテンツの一部が第２投影領域６ｂからはみ出して第１投影領域６ａに投影されたりして違和感が生じることを抑制することができる。 For example, when the first distance Zb between the projection device 10 and the second projection area 6b increases, the movable content projected on the second projection area 6b becomes unnaturally large relative to the second projection area 6b, It is possible to prevent a part of the movable content from protruding from the second projection area 6b and being projected onto the first projection area 6a, thereby preventing the user from feeling discomfort.
　また、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂの減少時に、第２投影領域６ｂに投影される可動コンテンツが第２投影領域６ｂに対して不自然に小さくなったり、可動コンテンツが第２投影領域６ｂよりも小さくなって背景コンテンツの一部が第２投影領域６ｂに投影されたりして違和感が生じることを抑制することができる。 Further, when the first distance Zb between the projection device 10 and the second projection area 6b is reduced, the movable content projected on the second projection area 6b becomes unnaturally small with respect to the second projection area 6b, It is possible to prevent the movable content from becoming smaller than the second projection area 6b and causing part of the background content to be projected onto the second projection area 6b.
　また、図５～図１０において説明したように、制御装置４は、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂに応じて、投影装置１０が投影対象への投影に用いる画像データのうち第２投影領域６ｂに投影される可動コンテンツの輝度を調整する加工処理を行う制御を実行する。輝度の調整は、エフェクトの変更の一例である。 Further, as described with reference to FIGS. 5 to 10, the control device 4 allows the projection device 10 to project onto the projection target according to the first distance Zb between the projection device 10 and the second projection area 6b. Control is executed to perform a processing process for adjusting the brightness of the movable content projected onto the second projection area 6b out of the image data. Adjusting brightness is an example of changing an effect.
　これにより、投影装置１０との間の距離が固定である第１投影領域６ａに投影される背景コンテンツの輝度は維持しつつ、投影装置１０との間の距離が可変である第２投影領域６ｂに投影される可動コンテンツの輝度を第２投影領域６ｂに合わせて調整することができる。このため、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂの変化があっても、第１投影領域６ａに投影される背景コンテンツと第２投影領域６ｂに投影される可動コンテンツの明るさをそれぞれ適切に維持し、投影品質を向上させることができる。 As a result, while maintaining the brightness of the background content projected onto the first projection area 6a whose distance from the projection device 10 is fixed, the second projection area 6b whose distance from the projection apparatus 10 is variable , the brightness of the movable content projected on the second projection area 6b can be adjusted. Therefore, even if there is a change in the first distance Zb between the projection device 10 and the second projection area 6b, the background content projected on the first projection area 6a and the movable content projected on the second projection area 6b brightness can be properly maintained and the projection quality can be improved.
　例えば、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂの増加時に、第２投影領域６ｂに投影される可動コンテンツが、第１投影領域６ａに投影される背景コンテンツに対して不自然に暗くなることを抑制することができる。 For example, when the first distance Zb between the projection device 10 and the second projection area 6b is increased, the movable content projected on the second projection area 6b is shifted relative to the background content projected on the first projection area 6a. Unnatural darkening can be suppressed.
　また、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂの減少時に、第２投影領域６ｂに投影される可動コンテンツが、第１投影領域６ａに投影される背景コンテンツに対して不自然に明るくなることを抑制することができる。 Also, when the first distance Zb between the projection device 10 and the second projection area 6b is reduced, the movable content projected on the second projection area 6b is reduced relative to the background content projected on the first projection area 6a. Unnatural brightness can be suppressed.
＜投影範囲１１における第２投影領域６ｂの位置の変化＞
　図１１及び図１２は、投影方向と直交する方向における第２投影領域６ｂの移動の一例を示す図である。第２投影領域６ｂは、投影装置１０の投影方向（例えば光軸Ｋの方向）の移動だけでなく、投影装置１０の投影方向と直交する方向に移動可能であってもよい。 <Change in Position of Second Projection Region 6b in Projection Range 11>
11 and 12 are diagrams showing an example of movement of the second projection area 6b in the direction orthogonal to the projection direction. The second projection area 6b may be movable not only in the projection direction of the projection device 10 (for example, the direction of the optical axis K), but also in a direction perpendicular to the projection direction of the projection device 10 .
　例えば、第２投影領域６ｂが、図７に示した位置から僅かに右に移動して図１１に示す位置に移動し、さらに図１１に示す位置から右に移動して図１２に示す位置に移動したとする。図１１に示す状態では、第２投影領域６ｂは投影範囲１１に収まっており、第２投影領域６ｂの全体に可動コンテンツを投影することが可能である。一方、図１２に示す状態では、第２投影領域６ｂの一部が投影範囲１１からはみ出しており、第２投影領域６ｂの全体に可動コンテンツを投影することができない。 For example, the second projection area 6b moves slightly to the right from the position shown in FIG. 7 to the position shown in FIG. 11, and further moves to the right from the position shown in FIG. 11 to the position shown in FIG. Suppose you move In the state shown in FIG. 11, the second projection area 6b is within the projection range 11, and it is possible to project movable content over the entire second projection area 6b. On the other hand, in the state shown in FIG. 12, part of the second projection area 6b protrudes from the projection range 11, and movable content cannot be projected on the entire second projection area 6b.
　制御装置４は、投影装置１０と第２投影領域６ｂとの間の位置関係を特定する。例えば、第２投影領域６ｂの移動が制御装置４の制御によって行われる場合は、制御装置４は第２投影領域６ｂの移動の制御結果に基づいて投影装置１０と第２投影領域６ｂとの位置関係を特定する。また、第２投影領域６ｂの移動が制御装置４とは別の装置の制御によって行われる場合は、制御装置４は、その別の装置から第２投影領域６ｂの移動の制御結果を受信することにより投影装置１０と第２投影領域６ｂとの位置関係を特定する。 The control device 4 identifies the positional relationship between the projection device 10 and the second projection area 6b. For example, when the movement of the second projection area 6b is controlled by the control device 4, the control device 4 changes the positions of the projection device 10 and the second projection area 6b based on the control result of the movement of the second projection area 6b. Identify relationships. In addition, when the movement of the second projection area 6b is performed by the control of a device other than the control device 4, the control device 4 receives the control result of the movement of the second projection region 6b from the other device. specifies the positional relationship between the projection device 10 and the second projection area 6b.
　また、制御装置４は、投影装置１０と第２投影領域６ｂとの位置関係を測定可能な測距装置から測距結果を受信することにより投影装置１０と第２投影領域６ｂとの位置関係を特定してもよい。測距装置は、投影装置１０に設けられていてもよいし、投影装置１０と通信可能な他の装置に設けられていてもよい。また、制御装置４は、操作受付部２を介してユーザから投影装置１０と第２投影領域６ｂとの位置関係の入力を受け付けることにより投影装置１０と第２投影領域６ｂとの位置関係を特定してもよい。 Further, the control device 4 receives the result of distance measurement from a distance measuring device capable of measuring the positional relationship between the projection device 10 and the second projection region 6b, thereby determining the positional relationship between the projection device 10 and the second projection region 6b. may be specified. The distance measuring device may be provided in the projection device 10 or may be provided in another device capable of communicating with the projection device 10 . In addition, the control device 4 specifies the positional relationship between the projection device 10 and the second projection region 6b by receiving an input of the positional relationship between the projection device 10 and the second projection region 6b from the user via the operation reception unit 2. You may
　そして、制御装置４は、特定した位置関係と、投影装置１０の仕様や設定によって決まる投影範囲１１の領域情報と、に基づいて、第２投影領域６ｂと投影範囲１１との位置関係を特定する。 Then, the control device 4 specifies the positional relationship between the second projection region 6b and the projection range 11 based on the specified positional relationship and the region information of the projection range 11 determined by the specifications and settings of the projection device 10. .
＜投影装置１０と第２投影領域６ｂとの位置関係に応じた画像加工＞
　図１３～図１６は、投影装置１０と第２投影領域６ｂとの位置関係に応じた画像加工の一例を示す図である。 <Image processing according to the positional relationship between the projection device 10 and the second projection area 6b>
13 to 16 are diagrams showing an example of image processing according to the positional relationship between the projection device 10 and the second projection area 6b.
　図１３は、図１１に示した状態における投影装置１０による投影を示している。画像６４は、図１３の例において制御装置４の制御によって光変調部２２へ入力される画像である。図１３の例においては、投影装置１０から見て、投影範囲１１における第２投影領域６ｂの中心位置が、例えば図１０に示した状態より右に移動している。このため、制御装置４は、第２投影領域６ｂの範囲に合わせて可動コンテンツが投影されるように、例えば図１０に示した状態よりも可動コンテンツを右に配置した画像６４を光変調部２２へ入力する制御を行う。 FIG. 13 shows projection by the projection device 10 in the state shown in FIG. An image 64 is an image input to the light modulation section 22 under the control of the control device 4 in the example of FIG. In the example of FIG. 13, the center position of the second projection area 6b in the projection range 11 has moved to the right from the state shown in FIG. For this reason, the control device 4 causes the light modulation unit 22 to display an image 64 in which the movable content is arranged to the right of the state shown in FIG. Controls input to
　図１４は、図１２に示した状態における投影装置１０による投影の第１の例を示している。画像６５は、図１４の例において制御装置４の制御によって光変調部２２へ入力される画像である。図１４の例においては、第２投影領域６ｂの一部が投影範囲１１から右にはみ出している。 FIG. 14 shows a first example of projection by the projection device 10 in the state shown in FIG. An image 65 is an image input to the light modulation section 22 under the control of the control device 4 in the example of FIG. In the example of FIG. 14, part of the second projection area 6b protrudes from the projection range 11 to the right.
　このため、制御装置４は、第２投影領域６ｂのうち投影範囲１１に含まれる範囲に可動コンテンツが投影されるように、可動コンテンツのサイズを縮小して配置した画像６５を光変調部２２へ入力する制御を行う。換言すると、制御装置４は、上記の第１距離Ｚｂに応じて可動コンテンツのサイズを変化させる制御を、投影範囲１１の範囲内で行う。 For this reason, the control device 4 transmits an image 65 in which the size of the movable content is reduced and arranged so that the movable content is projected in the range included in the projection range 11 in the second projection area 6b to the light modulation unit 22. Control input. In other words, the control device 4 performs control within the projection range 11 to change the size of the movable content according to the first distance Zb.
　図１５は、図１２に示した状態における投影装置１０による投影の第２の例を示している。画像６６は、図１５の例において制御装置４の制御によって光変調部２２へ入力される画像である。制御装置４は、第２投影領域６ｂのうち投影範囲１１に含まれる範囲に可動コンテンツが投影されるように、可動コンテンツの位置を調整して配置した画像６６を光変調部２２へ入力する制御を行ってもよい。換言すると、制御装置４は、上記の投影装置１０と第２投影領域６ｂとの位置関係に応じて可動コンテンツの位置を変化させる制御を、投影範囲１１の範囲内で行う。なお、図１５に示す第２の例においては、第１投影領域６ａの一部に可動コンテンツの一部が投影される場合がある。 FIG. 15 shows a second example of projection by the projection device 10 in the state shown in FIG. An image 66 is an image input to the light modulation section 22 under the control of the control device 4 in the example of FIG. The control device 4 controls inputting an image 66 arranged by adjusting the position of the movable content to the light modulation section 22 so that the movable content is projected in the range included in the projection range 11 in the second projection area 6b. may be performed. In other words, the control device 4 performs control to change the position of the movable content within the projection range 11 according to the positional relationship between the projection device 10 and the second projection area 6b. Note that in the second example shown in FIG. 15, part of the movable content may be projected onto part of the first projection area 6a.
　また、制御装置４は、図１４，図１５に示した処理を組み合わせ、第１距離Ｚｂに応じて可動コンテンツのサイズを変化させる制御と、投影装置１０と第２投影領域６ｂとの位置関係に応じて可動コンテンツの位置を変化させる制御と、を投影範囲１１の範囲内で実行してもよい。 In addition, the control device 4 combines the processes shown in FIGS. 14 and 15 to control the size of the movable content according to the first distance Zb and adjust the positional relationship between the projection device 10 and the second projection area 6b. and controlling to change the position of the movable content accordingly may be executed within the projection range 11 .
　図１６は、図１２に示した状態における投影装置１０による投影の第３の例を示している。画像６７は、図１６の例において制御装置４の制御によって光変調部２２へ入力される画像である。制御装置４は、第２投影領域６ｂの一部が投影範囲１１からはみ出す場合に、画像６７において背景コンテンツに重ね合わせる可動コンテンツの透過率を徐々に高める（すなわち可動コンテンツを徐々に消す）制御を行ってもよい。 FIG. 16 shows a third example of projection by the projection device 10 in the state shown in FIG. An image 67 is an image input to the light modulating section 22 under the control of the control device 4 in the example of FIG. When part of the second projection area 6b protrudes from the projection range 11, the control device 4 gradually increases the transmittance of the movable content superimposed on the background content in the image 67 (that is, gradually erases the movable content). you can go
　図１１～図１６に示したように、制御装置４は、投影装置１０と第２投影領域６ｂとの位置関係に応じて可動コンテンツの加工処理を行う制御を実行してもよい。これにより、投影装置１０の投影方向と異なる方向に第２投影領域６ｂが移動して投影範囲１１における第２投影領域６ｂの位置が変化しても、第１投影領域６ａに背景コンテンツを投影し第２投影領域６ｂに可動コンテンツを投影する状態を維持し、投影品質を向上させることができる。 As shown in FIGS. 11 to 16, the control device 4 may perform control for processing movable content according to the positional relationship between the projection device 10 and the second projection area 6b. As a result, even if the second projection area 6b moves in a direction different from the projection direction of the projection device 10 and the position of the second projection area 6b in the projection range 11 changes, the background content is projected onto the first projection area 6a. The projection quality can be improved by maintaining the state of projecting the movable content on the second projection area 6b.
　また、制御装置４は、第２投影領域６ｂの少なくとも一部が投影装置１０の投影範囲１１からはみ出る場合に可動コンテンツの加工処理を行う制御を実行してもよい。例えば、図１４，図１５に示したように、制御装置４は、第２投影領域６ｂのうち投影範囲１１からはみ出る部分を除いた領域に可動コンテンツが投影されるように、可動コンテンツの大きさ、及び可動コンテンツの位置の少なくともいずれかを変更する加工処理を行う制御を実行する。これにより、可動コンテンツの投影を継続し、見た目の違和感を抑制することができる。 In addition, the control device 4 may perform control to process the movable content when at least part of the second projection area 6b protrudes from the projection range 11 of the projection device 10 . For example, as shown in FIGS. 14 and 15, the control device 4 adjusts the size of the movable content so that the movable content is projected onto a region of the second projection region 6b excluding the portion protruding from the projection range 11. , and the position of the movable content. As a result, it is possible to continue projecting the movable content and suppress the discomfort in appearance.
　又は、図１６に示したように、制御装置４は、第２投影領域６ｂの少なくとも一部が投影範囲１１からはみ出る場合に、可動コンテンツのエフェクト（例えば透過率）を変更する加工処理を行う制御を実行してもよい。これにより、はみ出る可動コンテンツを徐々に消したり、又は印象的な演出を加えて消したりして、見た目の違和感を抑制することができる。 Alternatively, as shown in FIG. 16, when at least part of the second projection area 6b protrudes from the projection range 11, the control device 4 performs control to change the effect (for example, transmittance) of the movable content. may be executed. As a result, the protruding movable content can be gradually erased, or erased with an impressive presentation, thereby suppressing a sense of incongruity in appearance.
＜制御装置４による処理＞
　図１７は、制御装置４による処理の一例を示すフローチャートである。制御装置４は、例えば図１７に示す処理を実行する。この処理は、例えば制御装置４による実際の投影の前に行われる。 <Processing by control device 4>
FIG. 17 is a flowchart showing an example of processing by the control device 4. As shown in FIG. The control device 4 executes the processing shown in FIG. 17, for example. This processing is performed before the actual projection by the control device 4, for example.
　まず、制御装置４は、投影のための各種の情報を取得する（ステップＳ１７１）。ステップＳ１７１の処理は、例えば操作受付部２を介してユーザ操作を受け付けることによって行われる。ステップＳ１７１の処理については図１８において後述する。 First, the control device 4 acquires various information for projection (step S171). The processing of step S171 is performed by accepting a user operation via the operation accepting unit 2, for example. The processing of step S171 will be described later with reference to FIG.
　次に、制御装置４は、ステップＳ１７１によって取得した情報に基づいて、光変調部２２へ入力する画像の生成において背景コンテンツに重ね合わせる可動コンテンツの調整を行う（ステップＳ１７２）。ステップＳ１７２の処理については図１９において後述する。次に、制御装置４は、ステップＳ１７２により調整を行った可動コンテンツを用いて投影制御を行い（ステップＳ１７３）、一連の処理を終了する。 Next, based on the information acquired in step S171, the control device 4 adjusts the movable content to be superimposed on the background content in generating the image to be input to the light modulation section 22 (step S172). The processing of step S172 will be described later with reference to FIG. Next, the control device 4 performs projection control using the movable content adjusted in step S172 (step S173), and ends the series of processes.
　ステップＳ１７３における制御装置４による投影制御について説明する。制御装置４は、光変調部２２へ入力する画像の生成において背景コンテンツに重ね合わせる可動コンテンツについて、例えば以下の補正を行う。すなわち、制御装置４は、ステップＳ１７２により調整を行った可動コンテンツの輝度Ｌｂａｓｅを、例えば下記（１）式を用いて、第１距離Ｚｂが長くなるほど高くなるように補正する。Ｌ（Ｚｂ）は、第１距離Ｚｂに基づいて補正した可動コンテンツの輝度である。 The projection control by the control device 4 in step S173 will be described. The control device 4 performs, for example, the following corrections on movable content to be superimposed on background content in generating an image to be input to the light modulation section 22 . That is, the control device 4 corrects the luminance Lbase of the movable content adjusted in step S172 so as to increase as the first distance Zb increases, for example, using the following equation (1). L(Zb) is the luminance of the movable content corrected based on the first distance Zb.
　Ｌ（Ｚｂ）＝Ｌｂａｓｅ×（Ｚｂ／Ｚｂａｓｅ）２　　…（１） L(Zb)=Lbase×(Zb/Zbase) 2 (1)
　また、制御装置４は、ステップＳ１７２により調整を行った可動コンテンツの面積Ｓｂａｓｅを、例えば下記（２）式を用いて、第１距離Ｚｂが長くなるほど小さくなるように補正する。Ｓ（Ｚｂ）は、第１距離Ｚｂに基づいて補正した可動コンテンツの面積である。面積は、ピクセル数であってもよいし、画像全体（投影範囲１１）において占める割合であってもよい。 In addition, the control device 4 corrects the area Sbase of the movable content adjusted in step S172 so as to decrease as the first distance Zb increases, for example, using the following equation (2). S(Zb) is the area of the movable content corrected based on the first distance Zb. The area may be the number of pixels, or may be the ratio of the entire image (projection range 11).
　Ｓ（Ｚｂ）＝Ｓｂａｓｅ×（Ｚｂａｓｅ／Ｚｂ）　　…（２） 　S(Zb)=Sbase×(Zbase/Zb)...(2)
　制御装置４は、投影装置１０による実際の投影時に、第１距離Ｚｂに基づいて補正した輝度Ｌ（Ｚｂ）及び面積Ｓ（Ｚｂ）となるように補正した可動コンテンツを背景コンテンツに重ね合わせることにより生成した画像を光変調部２２に入力する投影制御を行う。また、ステップＳ１７２において可動コンテンツの輝度や面積や上限等の設定（クリップ処理）を行った場合、制御装置４は、この上限等の範囲内で可動コンテンツの補正を行いながらこの投影制御を行う。 At the time of actual projection by the projection device 10, the control device 4 superimposes the movable content corrected to have the luminance L (Zb) and the area S (Zb) corrected based on the first distance Zb on the background content. Projection control is performed to input the generated image to the light modulation unit 22 . Also, when the brightness, area, upper limit, and the like of the movable content are set (clip processing) in step S172, the control device 4 performs this projection control while correcting the movable content within the range of the upper limit and the like.
　図１８は、図１７に示したステップＳ１７１の処理の一例を示すフローチャートである。図１７に示したステップＳ１７１において、制御装置４は、例えば図１８に示す処理を実行することにより、情報の入力を受け付ける。 FIG. 18 is a flow chart showing an example of the process of step S171 shown in FIG. In step S171 shown in FIG. 17, the control device 4 accepts input of information by executing the process shown in FIG. 18, for example.
　まず、制御装置４は、光変調部２２へ入力される画像における可動コンテンツの指定を受け付ける（ステップＳ１８１）。次に、制御装置４は、第１距離Ｚｂの基準となる基準第１距離Ｚｂａｓｅを取得する（ステップＳ１８２）。元の可動コンテンツは、投影装置１０と第２投影領域６ｂとの間の第１距離Ｚｂがこの基準第１距離Ｚｂａｓｅにおいて最適となるように調整される。 First, the control device 4 accepts designation of movable content in an image input to the light modulation section 22 (step S181). Next, the control device 4 acquires a reference first distance Zbase that serves as a reference for the first distance Zb (step S182). The original movable content is adjusted such that the first distance Zb between the projection device 10 and the second projection area 6b is optimal at this reference first distance Zbase.
　次に、制御装置４は、投影距離の最大値である最大投影距離Ｚｍａｘと投影距離の最最小値である最小投影距離Ｚｍｉｎとを取得する（ステップＳ１８３）。次に、制御装置４は、輝度Ｌ（Ｚｂ）の最大値及び最小値を取得する（ステップＳ１８４）。輝度Ｌ（Ｚｂ）の最大値は、一例としては“２５５”である。輝度Ｌ（Ｚｂ）の最小値は、一例としては“１”である。 Next, the control device 4 acquires the maximum projection distance Zmax, which is the maximum projection distance, and the minimum projection distance Zmin, which is the minimum projection distance (step S183). Next, the control device 4 obtains the maximum and minimum values of the luminance L(Zb) (step S184). The maximum value of luminance L(Zb) is, for example, "255". The minimum value of luminance L(Zb) is, for example, "1".
　次に、制御装置４は、面積Ｓ（Ｚｂ）の最大値及び最小値を取得し（ステップＳ１８５）、一連の処理を終了する。面積Ｓ（Ｚｂ）の最大値は、一例としては“８０％”である。面積Ｓ（Ｚｂ）の最小値は、一例としては“２０％”である。 Next, the control device 4 obtains the maximum and minimum values of the area S (Zb) (step S185), and ends the series of processes. The maximum value of the area S (Zb) is, for example, "80%". The minimum value of the area S (Zb) is, for example, "20%".
　図１９は、図１７に示したステップＳ１７２の処理の一例を示すフローチャートである。図１７に示したステップＳ１７２において、制御装置４は、例えば図１９に示す処理を実行することにより、可動コンテンツの調整を行う。ここでは少なくとも可動コンテンツが動画像である場合について説明する。 FIG. 19 is a flow chart showing an example of the process of step S172 shown in FIG. In step S172 shown in FIG. 17, the control device 4 adjusts the movable content by executing the process shown in FIG. 19, for example. Here, at least the case where the movable content is a moving image will be described.
　まず、制御装置４は、動画像である可動コンテンツの各フレームについて、Ｌ（Ｚｍａｘ）、Ｌ（Ｚｍｉｎ）、Ｓ（Ｚｍａｘ）及びＳ（Ｚｍｉｎ）を算出する（ステップＳ１９０１）。 First, the control device 4 calculates L(Zmax), L(Zmin), S(Zmax), and S(Zmin) for each frame of movable content that is a moving image (step S1901).
　Ｌ（Ｚｍａｘ）は、投影装置１０と第２投影領域６ｂとの間の第１距離ＺｂがステップＳ１８３によって取得した最大投影距離Ｚｍａｘであるときの可動コンテンツの輝度であり、例えば上記（１）式のＺｂに最大投影距離Ｚｍａｘを代入することにより算出される。Ｌ（Ｚｍｉｎ）は、第１距離ＺｂがステップＳ１８３によって取得した最小投影距離Ｚｍｉｎであるときの可動コンテンツの輝度であり、例えば上記（１）式のＺｂに最小投影距離Ｚｍｉｎを代入することにより算出される。Ｌ（Ｚｍａｘ）及びＬ（Ｚｍｉｎ）は、例えば各フレームの画素ごとに算出される。 L(Zmax) is the luminance of the movable content when the first distance Zb between the projection device 10 and the second projection area 6b is the maximum projection distance Zmax obtained in step S183, for example, the above equation (1) is calculated by substituting the maximum projection distance Zmax into Zb of .

It can be adjusted according to the area 6b. Therefore, even if the first distance Zb between the projection device 10 and the second projection area 6b changes, the background content is projected on the first projection area 6a and the movable content is projected on the second projection area 6b. can be maintained and the projection quality can be improved.

　図２０は、複数の第２投影領域を用いた投影の一例を示す図である。図２０に示すように、投影装置１０は、複数の第２投影領域（第２投影領域６ｂ，６ｃ）に対して投影を行ってもよい。第２投影領域６ｃは、第２投影領域６ｂと同様に、第１投影領域６ａより小さく、第１投影領域６ａと投影装置１０との間に配置され、移動可能である。 <Projection using a plurality of second projection areas>
FIG. 20 is a diagram showing an example of projection using a plurality of second projection areas. As shown in FIG. 20, the projection device 10 may project onto a plurality of second projection areas ( second projection areas 6b and 6c). The second projection area 6c, like the second projection area 6b, is smaller than the first projection area 6a, is arranged between the first projection area 6a and the projection device 10, and is movable.
　制御装置４は、例えば、背景コンテンツに対して、第２投影領域６ｂに投影するための上記の可動コンテンツと、第２投影領域６ｃに投影するための可動コンテンツと、を重ね合わせて生成した画像を光変調部２２へ入力することにより、第１投影領域６ａに背景コンテンツを投影しつつ、第２投影領域６ｂ及び第２投影領域６ｃのそれぞれに可動コンテンツを投影する制御を行う。第２投影領域６ｃに投影するための可動コンテンツは、この例では、第２投影領域６ｂに投影するための可動コンテンツが示す人物の顔とは別の人物の顔の画像である。画像６８は、図２０の例において制御装置４の制御によって光変調部２２へ入力される画像である。 For example, the control device 4 generates an image by superimposing the movable content to be projected onto the second projection region 6b and the movable content to be projected onto the second projection region 6c with respect to the background content. is input to the light modulation unit 22, the background content is projected onto the first projection region 6a, and the moving content is projected onto the second projection region 6b and the second projection region 6c. In this example, the movable content to be projected onto the second projection area 6c is an image of a person's face different from the face of the person indicated by the movable content to be projected onto the second projection area 6b. An image 68 is an image input to the light modulation section 22 under the control of the control device 4 in the example of FIG.
　このような場合に、制御装置４は、投影装置１０と第２投影領域６ｂとの間の第２距離Ｚａに基づいて第２投影領域６ｂに投影する可動コンテンツの調整を行うとともに、投影装置１０と第２投影領域６ｃとの間の第２距離Ｚａに基づいて第２投影領域６ｃに投影する可動コンテンツの調整を行う。 In such a case, the control device 4 adjusts the movable content to be projected onto the second projection region 6b based on the second distance Za between the projection device 10 and the second projection region 6b. and the second projection area 6c, the movable content projected onto the second projection area 6c is adjusted.
