Description

画像投影装置Image projection device
　本発明は、二次元画像の虚像を用いて、三次元画像を表示するための画像投影装置に関する。 The present invention relates to an image projection apparatus for displaying a three-dimensional image using a virtual image of the two-dimensional image.
　複数のハーフミラーを用いて三次元映像を表示する技術が検討されている（例えば、特許文献１、２参照）。この特許文献１に記載された技術では、ハーフミラーの両側から背景と映像の合成映像により、立体感がある映像を表示する映像装置が開示されている。この映像装置では、対向させた２つの映像表示装置と、これら２つの映像表示装置の間に傾斜して設置されたハーフミラーを備える。 A technique for displaying a three-dimensional image using a plurality of half mirrors has been studied (see, for example, Patent Documents 1 and 2). In the technique described in Patent Document 1, a video device that displays a video with a stereoscopic effect from both sides of a half mirror by a synthesized video of a background and a video is disclosed. This video device includes two video display devices that face each other, and a half mirror that is installed inclined between the two video display devices.
　また、特許文献２に記載された技術では、一枚の二次元映像面を複数の映像領域に分割して個別の映像を表示し、これに複数のハーフミラーを一定に傾斜させて配置する。そして、観測者の視線方向に対して虚像が重なって見えることで三次元映像を表示する。 Further, in the technique described in Patent Document 2, a single two-dimensional image plane is divided into a plurality of image areas to display individual images, and a plurality of half mirrors are arranged with a constant inclination. Then, the virtual image appears to overlap the observer's line-of-sight direction, thereby displaying a 3D image.

　上述のような画像投影装置を用いて、ハーフミラーによる虚像を重ね合わせることにより、利用者に対して、立体感がある画像を提供することができる。しかしながら、画像投影装置の内部構造が見えたり、利用者に見せたい虚像以外の像が見えたりすると、視覚効果が劣化してしまう。従って、視覚効果を高く維持するために、不必要な画像や構造を、外部から見えないように遮蔽する必要がある。 By using the image projection apparatus as described above and superimposing virtual images by half mirrors, it is possible to provide a user with a stereoscopic effect. However, if the internal structure of the image projection device can be seen or if an image other than the virtual image that the user wants to see is seen, the visual effect will deteriorate. Therefore, in order to maintain a high visual effect, it is necessary to shield unnecessary images and structures from being visible from the outside.
　一方、今日では、スマートフォンやタブレット端末等、映像を出力機器が多く利用されている。このような外部の映像出力機器を利用して三次元画像を出力できると便利である。しかしながら、光源と一体化した画像投影装置と異なり、内部構造を遮蔽することは考慮されていなかった。 On the other hand, today, video output devices such as smartphones and tablet terminals are often used. It is convenient if a 3D image can be output using such an external video output device. However, unlike an image projection device integrated with a light source, shielding the internal structure has not been considered.

　（第１の実施形態）
　以下、本発明を具体化した第１の実施形態を、図１～図４に基づいて説明する。本実施形態では、図１に示す画像投影装置１０を用いる。図１（ａ）、（ｂ）は、それぞれ、本実施形態の画像投影装置１０の上面方向及び底面方向からの斜視図である。 (First embodiment)
A first embodiment embodying the present invention will be described below with reference to FIGS. In this embodiment, the image projection apparatus 10 shown in FIG. 1 is used. FIGS. 1A and 1B are perspective views from the top surface direction and the bottom surface direction of the image projection apparatus 10 of the present embodiment, respectively.
　図１（ａ）に示すように、画像投影装置１０は、本体を設置するため底面部１１ａを備えている。この底面部１１ａには、正面部１１ｂ、左右の側面部１１ｃが接続されている。ここで、正面部１１ｂの左右の端部は、左右の側面部１１ｃの正面側端部に接続されている。 As shown in FIG. 1 (a), the image projection apparatus 10 includes a bottom surface portion 11a for installing the main body. A front part 11b and left and right side parts 11c are connected to the bottom part 11a. Here, the left and right end portions of the front surface portion 11b are connected to the front side end portions of the left and right side surface portions 11c.
　また、左右の側面部１１ｃの背面側端部には、正面部１１ｂに対向して、図１（ｂ）に示すように背面部１１ｄが設けられている。この背面部１１ｄと底面部１１ａとの間には、開口部１３が設けられている。 Further, as shown in FIG. 1B, a back surface portion 11d is provided at the back side end portions of the left and right side surface portions 11c so as to face the front surface portion 11b. An opening 13 is provided between the back surface portion 11d and the bottom surface portion 11a.
　図１（ａ）に示すように、正面部１１ｂの上辺と、左右の側面部１１ｃの正面側端部には、底面部１１ａに対して所定の角度（本実施形態では４５度）で傾斜されたハーフミラー１４（透過性を有する反射材から構成された第１板）が狭持されている。本実施形態では、ハーフミラー１４は、反射率と透過率とがほぼ等しいものを用いる。 As shown in FIG. 1A, the upper side of the front part 11b and the front side end parts of the left and right side parts 11c are inclined at a predetermined angle (45 degrees in this embodiment) with respect to the bottom part 11a. Further, the half mirror 14 (a first plate made of a reflective material having transparency) is sandwiched. In the present embodiment, a half mirror 14 having substantially the same reflectance and transmittance is used.
　更に、ハーフミラー１４、左右の側面部１１ｃ、背面部１１ｄの各上辺には、上面部１１ｅが接続されている。この上面部１１ｅには、図１（ｂ）に示すように、開口部１６が設けられている。更に、上面部１１ｅのディスプレイ接触部には、開口部１６を覆うように、視野角制御フィルム１７が取り付けられている。この視野角制御フィルム１７は、正面から所定角度の視野範囲の光のみを透過するとともに、所定角度より大きい角度から入射する光の透過を抑制する視野角制御材である。例えば、羽板（ルーバー）を並行配列されたシートの両面を、透明性の高いフィルムで一体化したフィルムを用いることができる。本実施形態では、視野角が狭く、主に正面からの入射光のみを透過する視野角制御材を用いる。 Furthermore, an upper surface portion 11e is connected to each upper side of the half mirror 14, the left and right side surface portions 11c, and the back surface portion 11d. The upper surface portion 11e is provided with an opening 16 as shown in FIG. Further, a viewing angle control film 17 is attached to the display contact portion of the upper surface portion 11 e so as to cover the opening portion 16. The viewing angle control film 17 is a viewing angle control material that transmits only light in a viewing range of a predetermined angle from the front and suppresses transmission of light incident from an angle larger than the predetermined angle. For example, a film in which both sides of a sheet in which slats (louvers) are arranged in parallel can be integrated with a highly transparent film can be used. In the present embodiment, a viewing angle control material that has a narrow viewing angle and mainly transmits only incident light from the front is used.
　図２には、画像投影装置１０の六面図を示している。ここで、図２（ａ）は上面図、（ｂ）は正面図、（ｃ）は側面図、（ｄ）は背面図、（ｅ）は底面図である。
　図３及び図４は、画像投影装置１０の断面図を示している。この画像投影装置１０の内部において、底面部１１ａ上には、反射材１２ａが設けられている。更に、この反射材１２ａに対向して、対面領域に光を取り込む採光部１２ｂが設けられている。この採光部１２ｂは、透光性材（例えば、光を柔らかく拡散する曇りガラス材等）により構成する。この採光部１２ｂは、正面部１１ｂ、左右の側面部１１ｃに接続されている。そして、反射材１２ａを備えた底面部１１ａ、採光部１２ｂ、正面部１１ｂ、左右の側面部１１ｃにより、開口部１３が開放された空間が形成されている。 FIG. 2 shows a six-sided view of the image projector 10. 2A is a top view, FIG. 2B is a front view, FIG. 2C is a side view, FIG. 2D is a rear view, and FIG. 2E is a bottom view.
3 and 4 show cross-sectional views of the image projector 10. In the image projection apparatus 10, a reflective material 12a is provided on the bottom surface portion 11a. Further, a daylighting portion 12b that captures light into the facing area is provided opposite to the reflecting material 12a. The daylighting portion 12b is made of a translucent material (for example, a frosted glass material that softly diffuses light). This daylighting part 12b is connected to the front part 11b and the left and right side parts 11c. And the space | gap where the opening part 13 was open | released is formed by the bottom face part 11a provided with the reflecting material 12a, the daylighting part 12b, the front part 11b, and the side parts 11c on either side.
　更に、画像投影装置１０の内部には、ハーフミラー１４に並行してミラー１５（反射材から構成された第２板）が設けられている。このミラー１５は、全反射ミラーにより構成されており、採光部１２ｂ、左右の側面部１１ｃ、上面部１１ｅに接続されている。 Furthermore, a mirror 15 (a second plate made of a reflective material) is provided in parallel with the half mirror 14 inside the image projection apparatus 10. The mirror 15 is composed of a total reflection mirror, and is connected to the daylighting portion 12b, the left and right side surface portions 11c, and the upper surface portion 11e.
　本実施形態では、正面方向に対して、ハーフミラー１４の正面側端部の位置が、開口部１６の正面側端部（ディスプレイ２１の一端部）の位置に一致するように配置されている。また、ハーフミラー１４の背面側端部の位置が、開口部１６の中央位置に一致するように配置されている。更に、正面方向に対して、ミラー１５の正面側端部の位置が、開口部１６の中央位置（ディスプレイ２１の中央）に一致するように配置されている。また、ミラー１５の背面側端部の位置が、開口部１６の背面側端部の位置（ディスプレイ２１の他端部）に一致するように配置されている。 In the present embodiment, the position of the front end of the half mirror 14 with respect to the front direction is arranged to coincide with the position of the front end of the opening 16 (one end of the display 21). Further, the position of the rear side end of the half mirror 14 is arranged so as to coincide with the center position of the opening 16. Furthermore, the position of the front side end of the mirror 15 is arranged so as to coincide with the center position of the opening 16 (the center of the display 21) with respect to the front direction. Further, the position of the rear side end of the mirror 15 is arranged so as to coincide with the position of the rear side end of the opening 16 (the other end of the display 21).
　（作用）
　画像投影装置１０を使用する場合には、図４に示すように、画像を出力するディスプレイ２１を備えた画像再生端末２０を用いる。この画像再生端末２０のディスプレイ２１には、表示画面を上下二つの領域に分割し、それぞれの領域に別個の画像（２２、２３）を出力する。ここでは、歌手を表示した前方の画像２２（前方画像）と、背景を表示した後方の画像２３（後方画像）とを出力する場合を想定する。 (Function)
When using the image projection apparatus 10, as shown in FIG. 4, an image reproduction terminal 20 having a display 21 for outputting an image is used. On the display 21 of the image reproduction terminal 20, the display screen is divided into two upper and lower areas, and separate images (22, 23) are output to the respective areas. Here, it is assumed that a front image 22 (front image) displaying a singer and a rear image 23 (back image) displaying a background are output.
　そして、画像再生端末２０のディスプレイ２１を、画像投影装置１０の視野角制御フィルム１７に向けて密着させる。この場合、画像２２はミラー１５に投影されて、虚像３２を生成する。また、画像２３はミラー１５に投影されて、虚像３３を生成する。この場合、画像（２２、２３）と、ハーフミラー１４、ミラー１５の位置関係により、虚像３３は虚像３２の後方に生成される。 Then, the display 21 of the image reproduction terminal 20 is brought into close contact with the viewing angle control film 17 of the image projector 10. In this case, the image 22 is projected onto the mirror 15 to generate a virtual image 32. The image 23 is projected on the mirror 15 to generate a virtual image 33. In this case, the virtual image 33 is generated behind the virtual image 32 due to the positional relationship between the image (22, 23), the half mirror 14, and the mirror 15.
　更に、画像投影装置１０の開口部１３から、外光が画像投影装置１０内に侵入する。この外光は、反射材１２ａにより反射され、採光部１２ｂを介して、ハーフミラー１４、ミラー１５によって囲まれた空間に取り込まれる。 Furthermore, external light enters the image projector 10 through the opening 13 of the image projector 10. This external light is reflected by the reflecting material 12a and taken into the space surrounded by the half mirror 14 and the mirror 15 via the daylighting portion 12b.
　本実施形態によれば、以下のような効果を得ることができる。
　（１）上記実施形態では、画像投影装置１０は、正面側にハーフミラー１４、背面側にミラー１５を設ける。これにより、画像再生端末２０のディスプレイ２１に出力された画像の虚像３３は虚像３２の後方に生成される。これにより、正面側から虚像（３２、３３）を閲覧した場合、その位置関係により、三次元配置の立体感がある画像を生成することができる。従って、外付けの画像再生端末２０を用いて、簡単に立体画像を提供することができる。 According to this embodiment, the following effects can be obtained.
(1) In the above embodiment, the image projection apparatus 10 is provided with the half mirror 14 on the front side and the mirror 15 on the back side. Thereby, the virtual image 33 of the image output to the display 21 of the image reproduction terminal 20 is generated behind the virtual image 32. Thereby, when a virtual image (32, 33) is viewed from the front side, an image having a three-dimensional arrangement of three-dimensional arrangement can be generated based on the positional relationship. Therefore, a stereoscopic image can be easily provided using the external image playback terminal 20.
　（２）上記実施形態では、画像投影装置１０は、画像再生端末２０のディスプレイ２１を密着させる部分に視野角制御フィルム１７を設ける。これにより、画像投影装置１０の上面斜め方向から内部を覗き込んだ場合においても、内部構造を見ることができない。従って、利用者から内部構造や途中画像を遮蔽し、閉じられた空間を演出することができる。 (2) In the above-described embodiment, the image projection apparatus 10 provides the viewing angle control film 17 at a portion where the display 21 of the image reproduction terminal 20 is in close contact. Thereby, even when the inside is looked into from the upper surface oblique direction of the image projector 10, the internal structure cannot be seen. Therefore, it is possible to produce a closed space by shielding the internal structure and intermediate image from the user.
　（３）上記実施形態では、虚像（３２、３３）が生成される空間は、側面部１１ｃにより囲まれている。閉じられた空間での臨場感を出すことができる。更に、ハーフミラー１４の面と、側面部１１ｃの正面側端部の位置が一致しており、ハーフミラー１４の外側で、外部風景が視界に入ることになる。これにより、虚像との遠近感や開放感があり、更に臨場感を向上させることができる。 (3) In the above embodiment, the space in which the virtual image (32, 33) is generated is surrounded by the side surface portion 11c. You can give a sense of realism in a closed space. Furthermore, the position of the surface of the half mirror 14 and the position of the front side end of the side surface portion 11 c coincide with each other, and the external scenery enters the field of view outside the half mirror 14. Thereby, there is a sense of perspective and openness with a virtual image, and the sense of reality can be further improved.
　（４）上記実施形態では、画像投影装置１０は、開口部１３を設け、内部に採光部１２ｂを備える。これにより、画像投影装置１０の内部に、採光部１２ｂを介して、外光が取り込まれるので、画像投影装置１０内の空間が薄くライトアップされ、立体効果を促進させることができる。更に、画像投影装置１０の内部に、反射材１２ａを設けることにより、外光の取り込みの効率性を向上させることができる。 (4) In the embodiment described above, the image projection apparatus 10 includes the opening 13 and includes the daylighting unit 12b. Thereby, since external light is taken in into the inside of the image projector 10 via the lighting part 12b, the space in the image projector 10 is lighted up lightly, and a three-dimensional effect can be promoted. Furthermore, the efficiency of taking in external light can be improved by providing the reflecting material 12 a inside the image projection apparatus 10.
　（第２の実施形態）
　次に、本発明を具体化した第２の実施形態を図５に基づいて説明する。上記第１の実施形態においては、画像再生端末２０を水平にして、画像投影装置１０に設置した。本実施形態では、画像再生端末２０を立脚させた状態で、図５に示す画像投影装置１０ａを用いる。具体的には、クレードル８０に挿入して画像再生端末２０を立脚させた状態で、画像投影装置１０ａをディスプレイ２１上に密着させる。クレードル８０は、スタンド型の拡張機器であり、画像投影装置１０を載せるだけで接続することができ、画像再生端末２０のデータ同期、ファイル送受信、充電等を行なうために使われる。 (Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment, the image reproduction terminal 20 is installed horizontally on the image projection apparatus 10. In the present embodiment, the image projection device 10a shown in FIG. 5 is used in a state where the image reproduction terminal 20 is standing. Specifically, the image projecting device 10 a is brought into close contact with the display 21 in a state where the image reproducing terminal 20 is inserted into the cradle 80. The cradle 80 is a stand-type expansion device that can be connected simply by mounting the image projection device 10 and is used for data synchronization, file transmission / reception, charging, and the like of the image playback terminal 20.
　この画像投影装置１０ａは、ディスプレイ２１に密着させる視野角制御フィルム４１に対して、ミラー４２、ハーフミラー４３、ミラー４４が、それぞれ４５度の角度で並行して接続されている。更に、ハーフミラー４３の外側端部と、視野角制御フィルム４１との間には、視野角制御フィルム４５が設けられている。この視野角制御フィルム４５は、視野角制御フィルム４１に対してほぼ垂直方向に設けられている。この視野角制御フィルム４５も、正面から所定の角度の視野範囲の光のみを透過するとともに、所定角度より大きい角度から入射する光の透過を抑制する。 In this image projection apparatus 10a, a mirror 42, a half mirror 43, and a mirror 44 are connected in parallel at an angle of 45 degrees with respect to a viewing angle control film 41 to be brought into close contact with the display 21. Further, a viewing angle control film 45 is provided between the outer end of the half mirror 43 and the viewing angle control film 41. The viewing angle control film 45 is provided in a substantially vertical direction with respect to the viewing angle control film 41. The viewing angle control film 45 also transmits only light in a viewing range of a predetermined angle from the front, and suppresses transmission of light incident from an angle larger than the predetermined angle.
　図５には図示されていないが、画像投影装置１０ａには、画像再生端末２０のディスプレイ２１に面する開放部が設けられている。そして、本実施形態においても、ミラー４２の下端部の位置が、開口部の下端部（ディスプレイ２１の下端部）の位置に一致するように配置されている。また、ミラー４２の上端部の位置が、開口部の中央位置に一致するように配置されている。更に、ハーフミラー４３の下端部の位置が、開口部の中央位置（ディスプレイ２１の中央）に一致するように配置されている。また、ハーフミラー４３の上端部の位置が、開口部１６の上端部の位置（ディスプレイ２１の上端部）に一致するように配置されている。ミラー４４は、その下端部が、開口部１６の上端部の位置（ディスプレイ２１の上端部）に接続されている。画像投影装置１０ａは、視野角制御フィルム４１の対向面側に、ミラー４４の位置に対応して開口窓４６が形成されている。 Although not shown in FIG. 5, the image projection apparatus 10 a is provided with an open portion facing the display 21 of the image reproduction terminal 20. Also in the present embodiment, the position of the lower end portion of the mirror 42 is arranged to coincide with the position of the lower end portion of the opening (the lower end portion of the display 21). Further, the upper end portion of the mirror 42 is disposed so as to coincide with the center position of the opening. Furthermore, the position of the lower end part of the half mirror 43 is arrange | positioned so that it may correspond with the center position (center of the display 21) of an opening part. Further, the position of the upper end of the half mirror 43 is arranged so as to coincide with the position of the upper end of the opening 16 (the upper end of the display 21). The lower end of the mirror 44 is connected to the position of the upper end of the opening 16 (the upper end of the display 21). In the image projection device 10 a, an opening window 46 is formed on the opposite surface side of the viewing angle control film 41 corresponding to the position of the mirror 44.
　（作用）
　画像投影装置１０ａを使用する場合には、図５に示すように、画像再生端末２０のディスプレイ２１を、視野角制御フィルム４１に向けて密着させる。この場合も、この画像再生端末２０のディスプレイ２１には、表示画面を上下二つの領域に分割し、それぞれの領域に別個の画像（２２、２３）を出力する。 (Function)
When using the image projection device 10a, the display 21 of the image reproduction terminal 20 is brought into close contact with the viewing angle control film 41 as shown in FIG. Also in this case, the display screen of the image reproduction terminal 20 is divided into two upper and lower areas, and separate images (22, 23) are output to the respective areas.
　この画像２２は、ハーフミラー４３、ミラー４４に投影されて虚像３２を生成する。また、画像２３は、ミラー４２に投影され、ハーフミラー４３を透過し、ミラー４４によって反射されて虚像３３を生成する。この場合、虚像３２は、画像２２からミラー４４までの光路長だけ、ミラー４４から後方に生成される。一方、虚像３３は、画像２３からミラー４４までの光路長だけ、ミラー４４から後方の位置に生成される。 The image 22 is projected onto the half mirror 43 and the mirror 44 to generate a virtual image 32. The image 23 is projected onto the mirror 42, passes through the half mirror 43, and is reflected by the mirror 44 to generate a virtual image 33. In this case, the virtual image 32 is generated backward from the mirror 44 by the optical path length from the image 22 to the mirror 44. On the other hand, the virtual image 33 is generated at a position behind the mirror 44 by the optical path length from the image 23 to the mirror 44.
　本実施形態によれば、以下の効果を得ることができる。
　（５）上記実施形態では、画像投影装置１０ａは、下側にミラー４２、上側にハーフミラー４３を設ける。これにより、虚像３３は虚像３２の後方に生成される。これにより、正面側から虚像（３２、３３）を閲覧した場合、その位置関係により、三次元配置の立体感がある画像を生成することができる。従って、外付けの画像再生端末２０を用いて、簡単に立体画像を提供することができる。 According to the present embodiment, the following effects can be obtained.
(5) In the above embodiment, the image projection device 10a is provided with the mirror 42 on the lower side and the half mirror 43 on the upper side. As a result, the virtual image 33 is generated behind the virtual image 32.

Thereby, when the image 22 and the virtual image 33 are viewed from the front side, an image having a three-dimensional arrangement of stereoscopic effect can be generated based on the positional relationship. In particular, in this embodiment, since the number of mirrors can be reduced as compared with the second embodiment, a stereoscopic image can be provided more easily using the external image playback terminal 20.

　・　上記各実施形態においては、画像再生端末２０のディスプレイ２１に出力された二つの画像により、虚像３３，３２を生成する。ここで、画像投影装置１０を用いて、画像再生端末２０のディスプレイ２１における画像再生を制御できるようにしてもよい。この場合には、図７に示すように、静電容量方式のディスプレイ２１に対して、視野角制御フィルム１７上の不可視領域１７０に、接触時に特定の電気特性変化（静電容量の変化）を与える形状部として、導電性の突起部６１ａ，６１ｂを設ける。 In the above embodiments, the virtual images 33 and 32 are generated from the two images output to the display 21 of the image reproduction terminal 20. Here, the image reproduction on the display 21 of the image reproduction terminal 20 may be controlled using the image projection device 10. In this case, as shown in FIG. 7, a specific electric characteristic change (capacitance change) at the time of contact with the invisible region 170 on the viewing angle control film 17 is compared with the capacitance type display 21. Conductive protrusions 61a and 61b are provided as the shape portions to be provided.
　この不可視領域１７０としては、ディスプレイ２１において再生する複数の画面を分割する帯状の中間領域を用いる。この不可視領域１７０は、ディスプレイ２１に出力される別個の画像２２，２３に影響を与えない領域である。なお、不可視領域１７０は、画面を分割する中間領域に限定されるものではなく、画像２２，２３に影響を与えない領域を用いることができる。 As the invisible area 170, a band-shaped intermediate area that divides a plurality of screens reproduced on the display 21 is used. This invisible region 170 is a region that does not affect the separate images 22 and 23 output to the display 21. The invisible area 170 is not limited to the intermediate area that divides the screen, and an area that does not affect the images 22 and 23 can be used.
　また、図７においては、２個の突起部６１ａ，６１ｂを設けているが、その数は２個に限定されるものではない。この突起部６１ａ，６１ｂには、導電性シリコーンや導電性フォーム等のように、柔軟性がある導電性材料を用いることが可能である。これにより、ディスプレイ２１に密着させて電気的な接触を確実にするとともに、ディスプレイ２１の表面への傷付けを抑制することができる。 Moreover, in FIG. 7, although the two protrusion parts 61a and 61b are provided, the number is not limited to two pieces. For the protrusions 61a and 61b, a flexible conductive material such as conductive silicone or conductive foam can be used. Thereby, while making it closely_contact | adhere to the display 21 and ensuring an electrical contact, the damage to the surface of the display 21 can be suppressed.
　更に、画像投影装置１０において、外部から操作可能な領域に操作部を設ける。例えば、図７においては、正面部１１ｂに、操作部として操作ボタン６３ａ，６３ｂを設け、突起部６１ａ，６１ｂから配線６２ａ，６２ｂにより接続する。なお、操作ボタン６３ａ，６３ｂの場所は正面部１１ｂ上に限定されるものではなく、側面部１１ｃ上に設けることも可能である。 Furthermore, in the image projection apparatus 10, an operation unit is provided in an area that can be operated from the outside. For example, in FIG. 7, operation buttons 63a and 63b are provided as operation units on the front surface portion 11b, and the projections 61a and 61b are connected by wires 62a and 62b. The location of the operation buttons 63a and 63b is not limited to the front part 11b, but can be provided on the side part 11c.
　この配線６２ａ，６２ｂは、正面部１１ｂ、側面部１１ｃ等の内側に設けるとともに、タッチパネルディスプレイから絶縁しておく。更に、配線６２ａ，６２ｂは、静電気の帯電を防止するために、金属泊等のプレート状を用いるとともに、大気放電しやすいように全面的な被膜を有しないものが望ましい。 These wirings 62a and 62b are provided inside the front part 11b, the side part 11c, etc., and insulated from the touch panel display. Further, it is desirable that the wirings 62a and 62b have a plate shape such as a metal stay in order to prevent static electricity from being charged and do not have an overall coating so as to easily discharge to the atmosphere.
　次に、画像再生端末２０における画像再生処理の制御手順を、図８を用いて説明する。この場合、画像再生端末２０に格納された画像再生プログラムにより、画像再生端末２０の制御部（ＣＰＵ）を画像再生手段として機能させる。 Next, the control procedure of the image reproduction process in the image reproduction terminal 20 will be described with reference to FIG. In this case, the control unit (CPU) of the image reproduction terminal 20 is caused to function as an image reproduction unit by the image reproduction program stored in the image reproduction terminal 20.
　まず、画像再生端末２０の制御部は、容量検知を行なう（ステップＳ１）。この場合、画像再生端末２０は、不可視領域１７０における容量変化を検知する。ここでは、画像再生手段は、ディスプレイ２１の表面への突起部６１ａ，６１ｂの接触や、操作ボタン６３ａ，６３ｂにおける指の接触を容量変化により検知する。 First, the control unit of the image reproduction terminal 20 performs capacity detection (step S1). In this case, the image reproduction terminal 20 detects a capacity change in the invisible region 170. Here, the image reproducing means detects the contact of the protrusions 61a and 61b with the surface of the display 21 and the contact of the finger on the operation buttons 63a and 63b by changing the capacitance.
　次に、画像再生端末２０の制御部は、突起部に接触しているかどうかについての判定処理を実行する（ステップＳ２）。ここでは、画像再生手段は、検知した容量変化に基づいて、ディスプレイ２１の表面への突起部６１ａ，６１ｂの接触の有無を判定する。 Next, the control unit of the image reproduction terminal 20 performs a determination process as to whether or not the projection part is in contact (step S2). Here, the image reproduction means determines whether or not the protrusions 61a and 61b are in contact with the surface of the display 21 based on the detected capacitance change.
　ここで、突起部に接触していないと判定した場合（ステップＳ２において「ＮＯ」の場合）、画像再生端末２０の制御部は、画像再生を行なわない（ステップＳ３）。なお、画像再生中の場合には、ディスプレイ２１に表示された画像を消去するようにしてもよい。 Here, when it is determined that the protrusion is not in contact (in the case of “NO” in step S2), the control unit of the image reproduction terminal 20 does not perform image reproduction (step S3). Note that when the image is being reproduced, the image displayed on the display 21 may be erased.
　一方、突起部に接触していると判定した場合（ステップＳ２において「ＹＥＳ」の場合）、画像再生端末２０の制御部は、画像再生端末２０に記録されている画像を再生する（ステップＳ４）。具体的には、画像再生手段は、図４に示すように、表示画面を上下二つの領域に分割し、それぞれの領域に別個の画像（２２、２３）を出力する。 On the other hand, when it is determined that the protrusion is in contact (in the case of “YES” in step S2), the control unit of the image reproduction terminal 20 reproduces the image recorded in the image reproduction terminal 20 (step S4). . Specifically, as shown in FIG. 4, the image reproduction means divides the display screen into two upper and lower areas and outputs separate images (22, 23) in the respective areas.
　更に、画像再生端末２０の制御部は、操作されたかどうかについての判定処理を実行する（ステップＳ５）。ここでは、画像再生手段は、検知した容量変化に基づいて、操作ボタン６３ａ，６３ｂにおける指の接触の有無を判定する。 Further, the control unit of the image reproduction terminal 20 executes a determination process as to whether or not an operation has been performed (step S5). Here, the image reproduction means determines the presence or absence of a finger touch on the operation buttons 63a and 63b based on the detected capacitance change.
　ここで、操作されていないと判定した場合（ステップＳ５において「ＮＯ」の場合）、画像再生端末２０の制御部は、ステップＳ１の処理に戻る。
　一方、操作されたと判定した場合（ステップＳ５において「ＹＥＳ」の場合）、画像再生端末２０の制御部は、操作に応じた処理を実行し（ステップＳ６）、ステップＳ１の処理に戻る。 Here, when it is determined that it is not operated (in the case of “NO” in step S5), the control unit of the image reproduction terminal 20 returns to the process of step S1.
On the other hand, when it is determined that it has been operated (in the case of “YES” in step S5), the control unit of the image playback terminal 20 executes processing according to the operation (step S6), and returns to the processing of step S1.
　これにより、利用者から投影状況や途中画像を遮蔽して、閉じられた空間で、利用者の操作に応じた画像再生を演出することができる。
　なお、配線６２ａ，６２ｂ、操作ボタン６３ａ，６３ｂを設けず、視野角制御フィルム１７上の不可視領域１７０に突起部６１ａ，６１ｂを設けただけの構成としてもよい。この場合、画像再生手段は、ステップＳ１～Ｓ４までの処理を実行して、ステップＳ１の処理に戻る。これにより、画像再生端末２０が画像投影装置１０に設置されて、突起部６１ａ，６１ｂへの接触を検知している場合のみ、画像を再生させることができる。 Thereby, it is possible to produce an image reproduction according to the user's operation in the closed space by shielding the projection situation and the intermediate image from the user.
The wirings 62a and 62b and the operation buttons 63a and 63b may not be provided, and the protrusions 61a and 61b may be simply provided in the invisible region 170 on the viewing angle control film 17. In this case, the image reproduction means executes the processing from steps S1 to S4 and returns to the processing in step S1. Thereby, an image can be reproduced only when the image reproduction terminal 20 is installed in the image projection apparatus 10 and the contact with the protrusions 61a and 61b is detected.
　また、上記構成は、第２、第３の実施形態にも適用することが可能である。この場合には、視野角制御フィルム４１、視野角制御フィルム５１上において、不可視領域１７０に対応した領域に突起部６１ａ，６１ｂを設ける。 The above configuration can also be applied to the second and third embodiments. In this case, on the viewing angle control film 41 and the viewing angle control film 51, the protrusions 61a and 61b are provided in regions corresponding to the invisible region 170.
