　（実施形態）
　（１）概要
　本実施形態に係るスクリーンシステム１及び表示システム２は、図１に示すように、例えば、移動体１００に搭載されるシステムである。本実施形態では、移動体１００は、使用者である運転者によって運転される自動車であり、運転者を含む乗員を乗せた状態で路面上を走行する本体（車体）１０１を備えている。 (Embodiment)
(1) Outline The screen system 1 and the display system 2 according to the present embodiment are systems that are mounted on, for example, a moving body 100 as shown in FIG. In the present embodiment, the moving body 100 is an automobile driven by a driver who is a user, and includes a main body (vehicle body) 101 that travels on a road surface in a state where an occupant including the driver is placed.
　このような移動体１００において、使用者に対して移動体１００の運転に関連する運転関連情報を表す映像などで提示するために、本体１０１には、スクリーンシステム１を有する表示システム２が設けられている。ここで、使用者とは、移動体１００を利用（使用）する運転者などの乗員であり、移動体１００が客を乗せる自動車であれば、乗客を含んでもよい。 In such a moving body 100, a display system 2 having a screen system 1 is provided in the main body 101 in order to present a user with driving images related to driving the moving body 100. ing. Here, the user is an occupant such as a driver who uses (uses) the moving body 100, and may include passengers as long as the moving body 100 is a car on which a passenger is placed.
　スクリーンシステム１は、透光性を有するスクリーン部材１０（スクリーン）と、スクリーン部材１０の反射性能を制御する第１制御部２１（制御部）と、を備える。第１制御部２１は、スクリーン部材１０において映像５０（５１，５２）が投影される投影領域６０（６１，６２）での反射性能を、スクリーン部材１０において投影領域６０以外の非投影領域７０での反射性能よりも高くする。以下の説明において、複数の映像５１，５２に共通する説明を行う場合は映像５０と記載し、個々の映像について説明する場合は映像５１，５２と記載する。また、複数の投影領域６１，６２に共通する説明を行う場合は投影領域６０と記載し、個々の投影領域について説明する場合は投影領域６１，６２と記載する。 The screen system 1 includes a translucent screen member 10 (screen) and a first control unit 21 (control unit) that controls the reflection performance of the screen member 10. The first control unit 21 reflects the reflection performance in the projection area 60 (61, 62) where the image 50 (51, 52) is projected on the screen member 10 in the non-projection area 70 other than the projection area 60 on the screen member 10. Higher than the reflection performance. In the following description, a description common to a plurality of videos 51 and 52 is described as video 50, and an individual video is described as videos 51 and 52. In addition, the description common to the plurality of projection areas 61 and 62 is described as the projection area 60, and the individual projection areas are described as the projection areas 61 and 62.
　本実施形態のスクリーン部材１０はフロント投写型のスクリーンであり、スクリーン部材１０は投影システム３からの投影光を自動車の乗員に向かって反射することで映像を映し出している。スクリーン部材１０での反射には拡散反射、再帰反射、鏡面反射などがある。 The screen member 10 of the present embodiment is a front projection type screen, and the screen member 10 projects an image by reflecting the projection light from the projection system 3 toward the vehicle occupant. The reflection at the screen member 10 includes diffuse reflection, retroreflection, and specular reflection.
　本開示でいう「映像」は、文字、数字、絵文字、記号、図形、コンピュータグラフィックス、及び写真等の少なくとも１つの要素を含む映像であって、２つ以上の要素の組み合わせを含む映像であってもよい。さらに、「映像」は、モノクロ映像及びカラー映像のいずれでもよく、静止画及び動画のいずれでもよい。本実施形態では一例として、表示システム２によって表示（投影）される映像５０は、モノクロ映像の静止画であることとする。また、本開示において、「反射性能が高い」とは、スクリーン部材１０へ光を投影した場合の反射光が明るいことを意味し、「反射性能が低い」とは、スクリーン部材１０へ光を投影した場合の反射光が暗いことを意味する。換言すれば、反射性能が高いとは、スクリーン部材１０への投射光に対する反射光の輝度の比率（スクリーンゲイン）が高いこと意味する。本実施形態では、スクリーン部材１０が透光性を有しており、スクリーン部材１０において投影領域６０での光の透過率を変化させることで、投影領域６０の反射性能を部分的に変化させている。つまり、本実施形態では、スクリーン部材１０において投影領域６０での光の透過率を非投影領域７０よりも低下させることで、投影光が反射される割合を高めて、投影領域６０での反射性能を非投影領域７０よりも高めている。 The “video” in the present disclosure is a video including at least one element such as letters, numbers, pictograms, symbols, figures, computer graphics, and photographs, and includes a combination of two or more elements. May be. Furthermore, the “video” may be either a monochrome video or a color video, and may be a still image or a moving image. In the present embodiment, as an example, the video 50 displayed (projected) by the display system 2 is a monochrome video still image. In the present disclosure, “high reflection performance” means that the reflected light is bright when the light is projected onto the screen member 10, and “low reflection performance” means that the light is projected onto the screen member 10. This means that the reflected light is dark. In other words, the high reflection performance means that the ratio of the brightness of reflected light to the light projected onto the screen member 10 (screen gain) is high. In the present embodiment, the screen member 10 has translucency, and the reflection performance of the projection region 60 is partially changed by changing the light transmittance in the projection region 60 in the screen member 10. Yes. In other words, in the present embodiment, the light transmittance in the projection region 60 in the screen member 10 is lower than that in the non-projection region 70, thereby increasing the ratio of reflection of the projection light and reflecting performance in the projection region 60. Is higher than the non-projection region 70.
　また、本実施形態の表示システム２は、スクリーンシステム１と、スクリーンシステム１のスクリーン部材１０に映像を投影する投影システム３と、を備える。 Further, the display system 2 of the present embodiment includes a screen system 1 and a projection system 3 that projects an image on the screen member 10 of the screen system 1.
　本実施形態のスクリーンシステム１及び表示システム２では、投影領域６０に投影される映像５０の反射輝度が高くなり、使用者が映像５０を見やすくなる。また、非投影領域７０は投影領域６０に比べて反射性能が低いので、使用者が透光性を有するスクリーン部材１０を通して、スクリーン部材１０の向こう側の様子を見やすくなる。 In the screen system 1 and the display system 2 of the present embodiment, the reflected luminance of the image 50 projected on the projection region 60 is increased, and the user can easily view the image 50. In addition, since the non-projection area 70 has lower reflection performance than the projection area 60, the user can easily see the state of the screen member 10 through the screen member 10 having translucency.

The control unit 20 has, for example, a computer system (including a microcomputer) including a processor and a memory as a main configuration. That is, the computer system functions as the control unit 20 by executing an appropriate program on the processor.
　スクリーン部材１０は、移動体１００のウィンドシールド１０２において運転時の前方視界を妨げない場所に設けられている。本実施形態では、ウィンドシールド１０２の下端部に、ウィンドシールド１０２の幅方向（図１の左右方向）の全体に亘って、スクリーン部材１０が設けられている。図１では、説明の便宜上、ウィンドシールド１０２の上下方向の寸法に対してスクリーン部材１０の上下方向の寸法を比較的大きく図示しているが、スクリーン部材１０は運転中の運転者の視線よりも低い位置に設けられている。 The screen member 10 is provided in a place where the windshield 102 of the moving body 100 does not interfere with the forward view during driving. In the present embodiment, the screen member 10 is provided at the lower end of the windshield 102 over the entire width direction of the windshield 102 (left and right direction in FIG. 1). In FIG. 1, for convenience of explanation, the vertical dimension of the screen member 10 is relatively large with respect to the vertical dimension of the windshield 102, but the screen member 10 is larger than the line of sight of the driver during driving. It is provided at a low position.
　スクリーン部材１０は、例えば、電圧が印加されることによって光の透過率が変化する液晶パネルと、液晶パネルを両側から挟むガラス板とを備えている。例えば、液晶パネルの所望の部位に電圧が印加されると、液晶パネルの内部の液晶が規則的に配列されて、光の透過率が高くなるので、所望の部位での反射性能が低下する。一方、液晶パネルに電圧が印加されていない場合、液晶パネルの内部において液晶の配列が不規則になり、光の透過率が低くなるので、所望の部位での反射性能が高くなる。 The screen member 10 includes, for example, a liquid crystal panel whose light transmittance changes when a voltage is applied, and a glass plate that sandwiches the liquid crystal panel from both sides. For example, when a voltage is applied to a desired portion of the liquid crystal panel, the liquid crystal inside the liquid crystal panel is regularly arranged and the light transmittance is increased, so that the reflection performance at the desired portion is deteriorated. On the other hand, when no voltage is applied to the liquid crystal panel, the alignment of the liquid crystal becomes irregular inside the liquid crystal panel and the light transmittance is lowered, so that the reflection performance at a desired portion is improved.
　スクリーン部材１０は、ウィンドシールド１０２を構成するガラス板と一体に構成されていてもよいし、ウィンドシールド１０２を構成するガラス板に重ねて貼り付けられてもよい。 The screen member 10 may be configured integrally with a glass plate that constitutes the windshield 102, or may be laminated and pasted on the glass plate that constitutes the windshield 102.
　プロジェクタ装置３０は、支持台３１と投影部３２（プロジェクタ）とを備える。 The projector device 30 includes a support base 31 and a projection unit 32 (projector).
　支持台３１は本体１０１のダッシュボード付近に固定されている。支持台３１の上部には投影部３２が取り付けられている。 The support base 31 is fixed near the dashboard of the main body 101. A projection unit 32 is attached to the upper part of the support base 31.
　投影部３２は、例えば、レーザスキャン方式のプロジェクタである。投影部３２は、レーザ光を出力する半導体レーザ、半導体レーザから出力されるレーザ光を反射するＭＥＭＳ（Ｍｉｃｒｏ　Ｅｌｅｃｔｒｏ　Ｍｅｃｈａｎｉｃａｌ　Ｓｙｓｔｅｍｓ）ミラー等を備えている。投影部３２は、ＭＥＭＳミラーを使って、半導体レーザから出力されるレーザ光を走査することで、スクリーン部材１０の所望の投影領域６０に映像５０を投影する。 The projection unit 32 is, for example, a laser scanning projector. The projection unit 32 includes a semiconductor laser that outputs laser light, a MEMS (Micro Electro Mechanical Systems) mirror that reflects laser light output from the semiconductor laser, and the like. The projection unit 32 projects the image 50 on a desired projection region 60 of the screen member 10 by scanning the laser beam output from the semiconductor laser using the MEMS mirror.
　コンテンツ生成部４０は、例えば、プロセッサ及びメモリを含むコンピュータシステム（マイクロコンピュータを含む）を主構成とする。すなわち、コンピュータシステムは、適宜のプログラムをプロセッサにて実行することにより、コンテンツ生成部４０として機能する。 The content generation unit 40 has, for example, a computer system (including a microcomputer) including a processor and a memory as a main configuration. That is, the computer system functions as the content generation unit 40 by executing an appropriate program on the processor.
　コンテンツ生成部４０は、例えば、移動体１００が備える先進運転支援システム（ＡＤＡＳ：Ａｄｖａｎｃｅｄ　Ｄｒｉｖｅｒ　Ａｓｓｉｓｔａｎｃｅ　Ｓｙｓｔｅｍ）１１０から、移動体１００の運転に関連する運転関連情報が入力される。先進運転支援システム１１０は、例えば、移動体１００の周囲を撮影するＣＭＯＳ（Ｃｏｍｐｌｅｍｅｎｔａｒｙ　Ｍｅｔａｌ　Ｏｘｉｄｅ　Ｓｅｍｉｃｏｎｄｕｃｔｏｒ）イメージセンサの画像情報をもとに、移動体１００の周囲に存在する物体を検知すると、移動体１００の周囲に存在する物体の情報を運転関連情報としてコンテンツ生成部４０に出力する。図１の例では、移動体１００の左前方に人２０１が存在し、移動体１００の右前方に自動車２０２が存在している。先進運転支援システム１１０は、移動体１００の周囲に存在する人２０１及び自動車２０２を検知すると、人２０１及び自動車２０２の存在とその検出方向等を示す情報を運転関連情報としてコンテンツ生成部４０に出力する。コンテンツ生成部４０は、先進運転支援システム１１０から運転関連情報が入力されると、人２０１及び自動車２０２をそれぞれ表す映像５１，５２の映像データを生成する。コンテンツ生成部４０は、映像５１，５２の映像データを生成すると、映像５１，５２の映像データとその表示位置を示す位置情報とその投影時刻を示す同期信号を制御部２０に出力する。さらに、映像データと位置情報と同期信号は、第１制御部２１と第２制御部２２に入力されても良いし、図示しない別の回路で第１制御部２１と第２制御部２２に適用するように処理されてから入力されても良い。 The content generation unit 40 receives, for example, driving-related information related to driving of the moving body 100 from an advanced driving assistance system (ADAS: Advanced Driver Assistance System) 110 included in the moving body 100. The advanced driving support system 110 detects, for example, an object existing around the moving body 100 based on image information of a CMOS (Complementary Metal Oxide Semiconductor) image sensor that captures the surroundings of the moving body 100. Is output to the content generation unit 40 as driving-related information. In the example of FIG. 1, a person 201 exists on the left front side of the moving body 100, and an automobile 202 exists on the right front side of the moving body 100. When the advanced driving support system 110 detects the person 201 and the automobile 202 existing around the moving body 100, the information indicating the presence of the person 201 and the automobile 202 and the detection direction thereof is output to the content generation unit 40 as driving related information. To do. When the driving related information is input from the advanced driving support system 110, the content generation unit 40 generates video data of videos 51 and 52 representing the person 201 and the car 202, respectively. When the content generation unit 40 generates the video data of the videos 51 and 52, the content generation unit 40 outputs the video data of the videos 51 and 52, position information indicating the display position thereof, and a synchronization signal indicating the projection time to the control unit 20. Furthermore, the video data, the position information, and the synchronization signal may be input to the first control unit 21 and the second control unit 22, or may be applied to the first control unit 21 and the second control unit 22 by another circuit (not shown). It may be input after being processed.
　時刻は世界標準時とは限らず、スクリーンシステム１内で共通に使用される時刻でもよい。 The time is not limited to the universal time, but may be a time used in the screen system 1 in common.
　制御部２０は、スクリーン部材１０の反射性能を制御する第１制御部２１と、投影システム３を制御する第２制御部２２とを備える。反射性能を制御する制御と投影システム３を制御する制御を２つの制御部に分けずに１つの制御部で制御してもよい。 The control unit 20 includes a first control unit 21 that controls the reflection performance of the screen member 10 and a second control unit 22 that controls the projection system 3. The control for controlling the reflection performance and the control for controlling the projection system 3 may be controlled by one control unit without being divided into two control units.
　第１制御部２１は、スクリーン部材１０の反射性能を制御する。第１制御部２１は、スクリーン部材１０において映像５０（５１，５２）が投影される投影領域６０（６１，６２）での反射性能を、非投影領域７０での反射性能よりも高くする。具体的には、第１制御部２１は、スクリーン部材１０の投影領域６０においてスクリーン部材１０が備える液晶パネルに電圧を印加しないことで、電圧が印加されていない部位の光の透過率を、電圧が印加されている部位の光の透過率よりも低くして、反射性能を高くする。第１制御部２１には、コンテンツ生成部４０から映像５０の表示位置を示す位置情報と、映像５０の投影時刻を示す同期信号などの情報が入力されており、この位置情報と同期信号に基づいて映像５０が投影される投影領域６０の反射性能を高くする反射性能制御を行う。すなわち、第１制御部２１は、投影システム３がスクリーン部材１０に映像５０を投影する投影動作に同期して、映像５０の投影領域６０の反射性能を高くすることができる。ここにおいて、投影領域６０は、投影領域６２のように投影する映像５０の形状に合わせて映像５０の形状を若干大きくしたような形状に設定されてもよいし、投影領域６１のように映像５０を投影可能な長方形に設定されてもよい。具体的には、スクリーン部材１０の反射性能を変更する単位を細かくすれば映像５０の形状に合わせることができ、視認性を高くすることができる。しかしながら、長方形にした場合、位置情報を少なくし、処理を短時間で行うことができ、消費電力を抑えることができる。 The first control unit 21 controls the reflection performance of the screen member 10. The first control unit 21 makes the reflection performance in the projection area 60 (61, 62) where the image 50 (51, 52) is projected on the screen member 10 higher than the reflection performance in the non-projection area 70. Specifically, the first control unit 21 does not apply a voltage to the liquid crystal panel included in the screen member 10 in the projection region 60 of the screen member 10, thereby determining the light transmittance of a portion where no voltage is applied. The reflection performance is increased by lowering the light transmittance of the portion to which is applied. Position information indicating the display position of the video 50 and information such as a synchronization signal indicating the projection time of the video 50 are input from the content generation unit 40 to the first control unit 21, and based on the position information and the synchronization signal. Thus, the reflection performance control is performed to increase the reflection performance of the projection area 60 on which the image 50 is projected. That is, the first control unit 21 can improve the reflection performance of the projection region 60 of the image 50 in synchronization with the projection operation in which the projection system 3 projects the image 50 onto the screen member 10. Here, the projection area 60 may be set to a shape in which the shape of the image 50 is slightly enlarged in accordance with the shape of the image 50 to be projected like the projection area 62, or the image 50 like the projection area 61. May be set to a rectangle that can be projected. Specifically, if the unit for changing the reflection performance of the screen member 10 is made finer, it can be matched to the shape of the image 50, and the visibility can be enhanced. However, when the rectangular shape is used, position information can be reduced, processing can be performed in a short time, and power consumption can be suppressed.
　第２制御部２２は、コンテンツ生成部４０から入力される映像データ及び位置情報と、同期信号に基づいて、投影システム３によるスクリーン部材１０への映像の投影動作を制御する。第２制御部２２には、コンテンツ生成部４０から映像５０の映像データとその表示位置を示す位置情報と、映像５０の投影時刻を示す同期信号が入力される。第２制御部２２は、映像データ及び位置情報と、同期信号に基づいて、第１制御部２１が映像５０の投影領域６０の反射性能を高くする反射性能制御と同期して位置情報で指定される投影領域６０に投影部３２から光を投影させて、映像データに応じた映像５０を表示させる。 The second control unit 22 controls the projection operation of the image onto the screen member 10 by the projection system 3 based on the image data and position information input from the content generation unit 40 and the synchronization signal. The second control unit 22 receives the video data of the video 50, position information indicating the display position thereof, and a synchronization signal indicating the projection time of the video 50 from the content generation unit 40. The second control unit 22 is specified by the position information in synchronization with the reflection performance control in which the first control unit 21 increases the reflection performance of the projection region 60 of the image 50 based on the video data, the position information, and the synchronization signal. The light is projected from the projection unit 32 onto the projection area 60 to be displayed, and the video 50 corresponding to the video data is displayed.
　（３）動作
　以下、本実施形態に係るスクリーンシステム１及び表示システム２の動作について説明する。 (3) Operation Hereinafter, operations of the screen system 1 and the display system 2 according to the present embodiment will be described.
　先進運転支援システム１１０は、例えばＣＣＤカメラから定期的に入力される画像情報を画像処理して、移動体１００の周囲に存在する物体を検知する。図１に示すように移動体１００の周囲に人２０１及び自動車２０２が存在する場合、先進運転支援システム１１０は、人２０１及び自動車２０２の存在を検知し、移動体１００の周囲に存在する人２０１及び自動車２０２の情報を運転関連情報としてコンテンツ生成部４０に出力する。 The advanced driving support system 110 detects an object existing around the moving body 100 by performing image processing on, for example, image information periodically input from a CCD camera. As shown in FIG. 1, when the person 201 and the automobile 202 exist around the moving body 100, the advanced driving support system 110 detects the existence of the person 201 and the automobile 202, and the person 201 existing around the moving body 100. And the information of the automobile 202 is output to the content generation unit 40 as driving related information.
　コンテンツ生成部４０は、先進運転支援システム１１０から運転関連情報として人２０１及び自動車２０２の情報が入力されると、人２０１及び自動車２０２をそれぞれ表す映像５１，５２の映像データを生成する。コンテンツ生成部４０は、生成した映像５１，５２の映像データとその表示位置を示す位置情報を制御部２０に出力する。なお、コンテンツ生成部４０は、スクリーン部材１０に投影させる複数種類の映像の映像データをメモリに予め記憶しておいてもよい。コンテンツ生成部４０は、運転関連情報に基づいて表示する映像の映像データがメモリに記憶されていれば、この映像データをメモリから読み出し、メモリから読み出した映像データと位置情報とを制御部２０に出力すればよい。 When the information on the person 201 and the automobile 202 is input as the driving-related information from the advanced driving support system 110, the content generation unit 40 generates video data of videos 51 and 52 representing the person 201 and the automobile 202, respectively. The content generation unit 40 outputs the generated video data of the videos 51 and 52 and position information indicating the display position to the control unit 20. The content generation unit 40 may store in advance a plurality of types of video data to be projected on the screen member 10 in a memory. If the video data of the video to be displayed based on the driving related information is stored in the memory, the content generation unit 40 reads the video data from the memory, and sends the video data and the position information read from the memory to the control unit 20. Just output.
　コンテンツ生成部４０から制御部２０（第１制御部２１、第２制御部２２）に映像データと位置情報とが入力されると、第１制御部２１は、表示位置に基づいて投影領域６０の反射性能を非投影領域７０の反射性能よりも高くする。例えば、第１制御部２１は、スクリーン部材１０が有する液晶パネルにおいて非投影領域７０に電圧を印加することで、非投影領域７０での光の透過率を投影領域６０での光の透過率よりも高くする。また、第１制御部２１は、スクリーン部材１０が有する液晶パネルにおいて投影領域６０には電圧を印加せず、投影領域６０での光の透過率を非投影領域７０での光の透過率よりも低くすることで、投影領域６０での反射性能を非投影領域７０での反射性能よりも高くする。 When the video data and the position information are input from the content generation unit 40 to the control unit 20 (the first control unit 21 and the second control unit 22), the first control unit 21 sets the projection area 60 based on the display position. The reflection performance is set higher than that of the non-projection area 70. For example, the first control unit 21 applies a voltage to the non-projection region 70 in the liquid crystal panel included in the screen member 10, thereby causing the light transmittance in the non-projection region 70 to be greater than the light transmittance in the projection region 60. Also make it high. Further, the first control unit 21 does not apply a voltage to the projection region 60 in the liquid crystal panel included in the screen member 10, and the light transmittance in the projection region 60 is higher than the light transmittance in the non-projection region 70. By lowering, the reflection performance in the projection area 60 is made higher than the reflection performance in the non-projection area 70.
　また、第２制御部２２は、映像データ及び位置情報が入力されると、投影システム３を制御して、投影部３２から表示位置（投影領域６０）に光を投影させることで、投影領域６０に映像５０を表示させる。 In addition, when the video data and the position information are input, the second control unit 22 controls the projection system 3 to project light from the projection unit 32 onto the display position (projection region 60), thereby causing the projection region 60 to be projected. The video 50 is displayed on the screen.
　このように、スクリーン部材１０において非投影領域７０に比べて反射性能が高い投影領域６０に映像５０が投影されるから、映像５０の輝度を高くして、使用者が映像５０（５１，５２）を見えやすくできる。使用者は、スクリーン部材１０に表示された映像５１，５２をもとに、移動体１００の周囲に存在する人２０１や自動車２０２の存在に気付きやすくなり、使用者による運転作業を支援して、より安全な運転を実現することができる。また、スクリーン部材１０において映像５０が投影されない非投影領域７０の光の透過率は、投影領域６０の光の透過率よりも高くなるので、使用者はスクリーン部材１０を通して、スクリーン部材１０の向こう側の様子を見やすくなる。 Thus, since the image 50 is projected onto the projection region 60 having higher reflection performance than the non-projection region 70 on the screen member 10, the brightness of the image 50 is increased and the user can view the image 50 (51, 52). Can be seen easily. Based on the images 51 and 52 displayed on the screen member 10, the user can easily notice the presence of the person 201 and the automobile 202 around the moving body 100, and assists the driving operation by the user. Safer driving can be realized. In addition, since the light transmittance of the non-projection area 70 where the image 50 is not projected on the screen member 10 is higher than the light transmittance of the projection area 60, the user passes the screen member 10 and the other side of the screen member 10. It becomes easier to see the state of.

For example, in the projection system 3, the content generation unit 40 and the control unit 20 are realized by separate computer systems, but may be realized by a single computer system.
　また、上記の実施形態では、スクリーンシステム１及び投影システム３がそれぞれ１つのシステムで実現されているが、この構成に限らず、例えば、スクリーンシステム１及び投影システム３の各々が２以上のシステムで実現されてもよい。また、表示システム２は２つのシステム（スクリーンシステム１、投影システム３）で実現されているが、表示システムの機能が１つのシステムに集約されてもよい。すなわち、スクリーンシステム１、投影システム３、及び表示システム２の各機能が１つのシステムに集約されていてもよいし、２以上のシステムに分散して設けられてもよい。また、スクリーンシステム１、投影システム３、及び表示システム２の各機能が、複数の装置に分散して設けられていてもよい。例えば、スクリーンシステム１が備える第１制御部２１が２以上のシステムに分散して設けられてもよい。また、スクリーンシステム１、投影システム３、及び表示システム２の少なくとも一部の機能は、例えば、クラウド（クラウドコンピューティング）によって実現されてもよい。また、スクリーンシステム１の制御方法を制御部２０に実行させる主体は、移動体１００の外部に設けられたコンピュータシステムでもよい。例えば、移動体１００の外部のコンピュータシステムが、移動体１００の制御部２０とインターネットなどの通信網を介して通信を行い、スクリーン部材１０の反射性能を制御する制御処理を制御部２０（第１制御部２１）に実行させてもよい。 In the above embodiment, the screen system 1 and the projection system 3 are each realized by one system. However, the present invention is not limited to this configuration. For example, each of the screen system 1 and the projection system 3 is two or more systems. It may be realized.

The main body that causes the control unit 20 to execute the control method of the screen system 1 may be a computer system provided outside the moving body 100. For example, a computer system external to the mobile unit 100 communicates with the control unit 20 of the mobile unit 100 via a communication network such as the Internet, and performs control processing for controlling the reflection performance of the screen member 10 (first unit). It may be executed by the control unit 21).
　（４．１）変形例１
　上記の実施形態では、１つの映像５０を投影する１つの投影領域６０では反射性能が一様であったが、１つの投影領域６０が、反射性能が非投影領域７０よりも高い第１部位と、第１部位よりも反射性能が低い第２部位とを含んでもよい。 (4.1) Modification 1
In the above-described embodiment, the reflection performance is uniform in one projection region 60 that projects one image 50. However, one projection region 60 has a first portion whose reflection performance is higher than that of the non-projection region 70. And a second part having a lower reflection performance than the first part.
　例えば、図２に示すように、映像５１が投影される投影領域６１が、反射性能が非投影領域７０よりも高い第１部位６１Ａと、第１部位６１Ａよりも反射性能が低い第２部位６１Ｂとを含んでもよい。 For example, as shown in FIG. 2, the projection region 61 on which the video image 51 is projected includes a first part 61A having a higher reflection performance than the non-projection area 70 and a second part 61B having a lower reflection performance than the first part 61A. And may be included.
　ここで、投影領域６１は複数の第１部位６１Ａと複数の第２部位６１Ｂとを含んでいる。第１部位６１Ａ及び第２部位６１Ｂの形状は縦横の長さが同じ正方形であり、縦方向（図２の上下方向であって例えば鉛直方向）及び横方向（図２の左右方向であって例えば水平方向）に沿って第１部位６１Ａと第２部位６１Ｂとが交互に並んでいる。第２部位６１Ｂにおける光の透過率は、必ずしも非投影領域７０における光の透過率よりも低い必要は無いが、図２は、第２部位６１Ｂにおける光の透過率が非投影領域７０における光の透過率と同程度である場合の表示状態を示している。第１部位６１Ａに投影された光はスクリーン部材１０の表面で反射されるが、第２部位６１Ｂに投影された光はほとんど反射されずにスクリーン部材１０を透過するので、映像５１は第２部位６１Ｂに投影された部分が欠けたような映像になる。ここで、投影される映像５１の大きさに合わせて第１部位６１Ａ及び第２部位６１Ｂの大きさを調整しておけば、投影領域６１に投影された映像５１を使用者は視認でき、また第２部位６１Ｂを通してスクリーン部材１０の向こう側の様子を視認しやすくなる。よって、スクリーン部材１０に映像５１を表示させつつ、映像５１が投影される投影領域６１においてもスクリーン部材１０の向こう側の様子を部分的に確認することができる。 Here, the projection region 61 includes a plurality of first portions 61A and a plurality of second portions 61B. The shape of the first part 61A and the second part 61B is a square having the same vertical and horizontal lengths, and the vertical direction (the vertical direction in FIG. 2, for example, the vertical direction) and the horizontal direction (the horizontal direction in FIG. The first site 61A and the second site 61B are alternately arranged along the horizontal direction. The light transmittance in the second portion 61B does not necessarily need to be lower than the light transmittance in the non-projection region 70, but FIG. 2 shows that the light transmittance in the second portion 61B is the light transmittance in the non-projection region 70. The display state in the case of the same degree as the transmittance is shown. The light projected on the first part 61A is reflected on the surface of the screen member 10, but the light projected on the second part 61B is transmitted through the screen member 10 with almost no reflection. The image projected on 61B is missing. Here, if the size of the first part 61A and the second part 61B is adjusted according to the size of the projected image 51, the user can visually recognize the image 51 projected on the projection region 61, and It becomes easy to visually recognize the other side of the screen member 10 through the second portion 61B. Therefore, while the image 51 is displayed on the screen member 10, it is possible to partially confirm the state beyond the screen member 10 in the projection area 61 where the image 51 is projected.
　同様に、図３に示すように、映像５２が投影される投影領域６２が、反射性能が非投影領域７０よりも高い第１部位６２Ａと、第１部位６２Ａよりも反射性能が低い第２部位６２Ｂとを含んでもよい。 Similarly, as shown in FIG. 3, the projection region 62 on which the image 52 is projected includes a first portion 62A having a higher reflection performance than the non-projection region 70 and a second portion having a lower reflection performance than the first portion 62A. 62B may be included.
　ここで、投影領域６２は複数の第１部位６２Ａと複数の第２部位６２Ｂとを含んでいる。第１部位６２Ａ及び第２部位６２Ｂの形状は縦横の長さが同じ正方形であり、縦方向（図３の上下方向であって例えば鉛直方向）及び横方向（図３の左右方向であって例えば水平方向）に沿って第１部位６２Ａと第２部位６２Ｂとが交互に並んでいる。図３は、第２部位６２Ｂにおける光の透過率が非投影領域７０における光の透過率と同程度である場合の表示状態を示している。第１部位６２Ａに投影された光はスクリーン部材１０の表面で反射されるが、第２部位６２Ｂに投影された光はほとんど反射されずにスクリーン部材１０を透過するので、映像５２は第２部位６２Ｂに投影された部分が欠けたような映像になる。ここで、投影される映像５２の大きさに合わせて第１部位６２Ａ及び第２部位６２Ｂの大きさを調整しておけば、投影領域６２に投影された映像５２を使用者は視認でき、また第２部位６２Ｂを通してスクリーン部材１０の向こう側の様子を視認できる。よって、スクリーン部材１０に映像５２を表示させつつ、映像５２が投影される投影領域６２においてもスクリーン部材１０の向こう側の様子を部分的に確認することができる。 Here, the projection region 62 includes a plurality of first portions 62A and a plurality of second portions 62B. The shape of the first part 62A and the second part 62B is a square having the same vertical and horizontal lengths, and the vertical direction (the vertical direction in FIG. 3, for example, the vertical direction) and the horizontal direction (the horizontal direction in FIG. The first portions 62A and the second portions 62B are alternately arranged along the horizontal direction. FIG. 3 shows a display state in the case where the light transmittance in the second part 62 </ b> B is approximately the same as the light transmittance in the non-projection region 70. The light projected on the first part 62A is reflected on the surface of the screen member 10, but the light projected on the second part 62B is transmitted through the screen member 10 with almost no reflection. The image appears as if the portion projected onto 62B is missing. Here, if the size of the first part 62A and the second part 62B is adjusted according to the size of the projected image 52, the user can visually recognize the image 52 projected on the projection region 62, and The state beyond the screen member 10 can be visually recognized through the second portion 62B. Therefore, while the image 52 is displayed on the screen member 10, it is possible to partially confirm the state beyond the screen member 10 in the projection region 62 where the image 52 is projected.
　なお、第１部位６１Ａ，６２Ａ及び第２部位６１Ｂ，６２Ｂの形状は正方形であったが、第１部位６１Ａ，６２Ａ及び第２部位６１Ｂ，６２Ｂの形状及び大きさは適宜変更が可能である。また、第１部位６１Ａ，６２Ａ及び第２部位６１Ｂ，６２Ｂの形状及び大きさは互いに異なっていてもよい。 In addition, although the shape of 1st site | part 61A, 62A and 2nd site | part 61B, 62B was a square, the shape and magnitude | size of 1st site | part 61A, 62A and 2nd site | part 61B, 62B can be changed suitably. Further, the shapes and sizes of the first parts 61A and 62A and the second parts 61B and 62B may be different from each other.

　なお、変形例２において投影システム３が投影領域６３，６４に光を投影してもよい。投影領域６３，６４での反射性能は非投影領域７０での反射性能よりも高いので、例えば外光が少ない場合などに投影システム３が投影領域６３，６４に光を投影することで、投影領域６３，６４を見えやすくできる。また、投影システム３が投影領域６３，６４に所定の色の光を投影したり、投影領域６３，６４に映像を投影してもよく、投影領域６３，６４を目立たせることができる。 In the second modification, the projection system 3 may project light onto the projection areas 63 and 64. Since the reflection performance in the projection areas 63 and 64 is higher than the reflection performance in the non-projection area 70, the projection system 3 projects light onto the projection areas 63 and 64 when, for example, there is little external light. 63 and 64 can be easily seen. Further, the projection system 3 may project light of a predetermined color on the projection areas 63 and 64, or project an image on the projection areas 63 and 64, and the projection areas 63 and 64 can be made conspicuous.
