Abstract
Description
本発明は、一台の映像投映装置を用い、投映映像の内容に応じて投映方向を変化させる方法、装置及び投映台に関する。 The present invention relates to a method, an apparatus, and a projection stand for changing a projection direction according to the content of a projected video using a single video projection device.
特許文献１には、反射板を用いプロジェクターの投映方向を切替える映像投映装置が記載されている。この映像投映装置においては、投光レンズの前方に、光軸に対し略４５°に傾けた反射板を配備し、該反射板を左右反転可能及び着脱可能に取り付けることにより、投光レンズの前方及び側方の方向を切り換えて映像を投映するものである。この技術を用いると、前面に投映するタイプの映像投映装置で、床や天井、背面など別の方向に設置されたスクリーンにも映像を投映する事が可能である。 Patent Document 1 describes a video projection device that uses a reflector to switch the projection direction of a projector. In this video projection device, a reflector plate inclined approximately 45 ° with respect to the optical axis is provided in front of the projector lens, and the reflector plate is attached to the front of the projector lens so that it can be reversed left and right. And the video is projected by switching the direction of the side. Using this technology, it is possible to project images on a screen installed in another direction such as the floor, ceiling, or back, using a video projection device that projects on the front.
特許文献１に記載されているように、反射板を用いる事で、映像投映装置が、本来投映される映像の投映方向を変える装置は周知である。しかし、その投映装置は、予め使用者が投映装置に反射板を取り付けたり、反射板を手動で切替えたりする必要がある。したがって、投映映像の内容が切替わった時やシーンが変更したと同時に自動的に投映方向を変化させることが出来ない為、視聴者が臨場感を味わう事ができるものではない。すなわち、地面を映した映像を床面に、空を映した映像を上面に投映するなど、映像を投映する流れのなかで迅速に投映方向を変えることは出来なかった。本発明はかかる課題に鑑みてなされたものであり、その目的は投映映像の内容に応じて投映方向を変化させる方法及び装置を提供することを目的とする。 As described in Japanese Patent Application Laid-Open No. H10-228707, a device that changes the projection direction of a video that is originally projected by a video projection device by using a reflector is well known. However, the projection device requires that the user attach a reflection plate to the projection device in advance or manually switch the reflection plate. Therefore, since the projection direction cannot be automatically changed when the content of the projected video is changed or at the same time when the scene is changed, the viewer cannot experience a sense of realism. In other words, the projection direction could not be changed quickly in the course of projecting the image, such as projecting the image of the ground onto the floor and the image of the sky onto the top. The present invention has been made in view of such problems, and an object of the present invention is to provide a method and apparatus for changing the projection direction in accordance with the content of the projected video.
本発明を実現するための映像投映方法は、投映方向制御信号を受信するステップと、 前記投映方向制御信号に対応する命令信号を判別するステップと、判別された命令信号を出力するステップと、前記命令信号に基づき反射板を駆動するステップを含むことを特徴とする。 A video projection method for realizing the present invention includes a step of receiving a projection direction control signal, a step of determining a command signal corresponding to the projection direction control signal, a step of outputting the determined command signal, The method includes a step of driving the reflecting plate based on the command signal.
また、本発明を実現するための映像投映装置は、投映方向制御信号を受信する受信部と、前記投映方向制御信号に対応する命令信号を判別する判別部と、判別された命令信号を出力する命令部と、前記命令部からの命令信号に基づき反射板を駆動する駆動部を含むことを特徴とする。 In addition, a video projection device for realizing the present invention outputs a reception unit that receives a projection direction control signal, a determination unit that determines a command signal corresponding to the projection direction control signal, and a determined command signal An instruction unit and a driving unit for driving the reflector based on an instruction signal from the instruction unit are included.
また、本発明を実現するための投映台は、投映方向制御信号を受信する受信部と、前記投映方向制御信号に対応する命令信号を判別する判別部と、判別された命令信号を出力する命令部と、前記命令部からの命令信号に基づき反射板を駆動する駆動部を含み、映像投映装置が設置されることを特徴とする。 Further, a projection stand for realizing the present invention includes a receiving unit that receives a projection direction control signal, a determination unit that determines a command signal corresponding to the projection direction control signal, and a command that outputs the determined command signal And a drive unit that drives the reflector based on a command signal from the command unit, and an image projection device is installed.
また、本発明を実現するための映像投映システムは、電子機器と映像投映装置と投映台のうち少なくとも二つの機器からなる映像投映システムであって、電子機器と映像投映装置と投映台の各々は遠隔に配置され、遠隔送受信手段を具備すると共に、電子機器と映像投映装置と投映台のうち少なくとも二つの機器において、投映方向制御信号を受信する受信部と、前記投映方向制御信号に対応する命令信号を判別する判別部と、判別された命令信号を出力する命令部と、前記命令部からの命令信号に基づき反射板を駆動する駆動部とを具備することを特徴とする。 A video projection system for realizing the present invention is a video projection system composed of at least two devices among an electronic device, a video projection device, and a projection stand, and each of the electronic device, the video projection device, and the projection stand includes Remotely disposed, having remote transmission / reception means, and receiving unit for receiving projection direction control signal in at least two devices among electronic device, video projection device, and projection base, and a command corresponding to the projection direction control signal It is characterized by comprising: a discriminating unit for discriminating a signal; a command unit for outputting the discriminated command signal; and a drive unit for driving the reflector based on the command signal from the command unit.
投映映像の内容に応じて投映方向を変化させる、映像投映方法及び映像投映装置により、多方向へ映像を投映する時に映像投映装置を複数台用意する事がなく、さらに、投映映像の内容により投映方向を変化させることにより臨場感が追及できるという効果を有する。 With the video projection method and video projection device that changes the projection direction according to the content of the projected video, there is no need to prepare multiple video projection devices when projecting video in multiple directions, and projection is performed according to the content of the projected video. There is an effect that a sense of reality can be pursued by changing the direction.
本発明の処理を実現する為の映像投映装置、投映台、及びその方法について、以下、図面を用いて説明する。 A video projection apparatus, projection stand, and method for realizing the processing of the present invention will be described below with reference to the drawings.
〔実施形態１〕
図１は、本発明の処理を実現するための映像投映装置の概略図である。図１は、本発明の映像投映装置１０１の外観を例示したものであり、受信部１０２で投映方向制御信号を外部より受信し、その投映方向制御信号を元に映像投映装置内で処理を行い、反射板１０３を駆動し、投映方向を変化させる。投映方向制御信号を外部より受信してから反射板を駆動するまでの処理が、映像投映装置１０１内で行われる。
[Embodiment 1]
FIG. 1 is a schematic diagram of a video projection apparatus for realizing the processing of the present invention. FIG. 1 exemplifies the appearance of a video projection apparatus 101 according to the present invention. A reception unit 102 receives a projection direction control signal from the outside, and performs processing in the video projection apparatus based on the projection direction control signal. Then, the reflecting plate 103 is driven to change the projection direction. Processing from receiving a projection direction control signal from the outside to driving the reflector is performed in the video projection apparatus 101.
図２に、図１の映像投映装置にかかる要部構成図を示し、図３に、図２記載の各部が実施される為の処理フローを示す。映像投映装置は、投映方向制御信号２０４を受信部２０２で受信する（ステップ３０１。（以後、ステップをＳと表記する。））。次に、受信した投映方向制御信号に対応する命令信号を判別部２０５で判別する（Ｓ３０２）。判別された命令信号を命令部２０６から出力し（Ｓ３０３）、命令部からの命令信号に応じて駆動部２０７では反射板２０３を駆動する（Ｓ３０４）。 FIG. 2 shows a block diagram of the main part of the video projection apparatus shown in FIG. 1, and FIG. 3 shows a processing flow for implementing each part shown in FIG. The video projection apparatus receives the projection direction control signal 204 by the receiving unit 202 (Step 301 (hereinafter, “Step” will be referred to as “S”)). Next, the determination unit 205 determines a command signal corresponding to the received projection direction control signal (S302). The determined command signal is output from the command unit 206 (S303), and the drive unit 207 drives the reflector 203 in accordance with the command signal from the command unit (S304).
本発明は、投映方向の切替を行うための信号である投映方向制御信号が、少なくとも投映方向を変化させるタイミングで、予め投映映像のデータの一部に組み込まれており、そのデータを受信し、その投映方向制御信号を判別部で解析し、映像シーン・内容によって最適な反射板の位置（角度や方向）を制御する事で、投映映像の内容に応じて映像の投映方向を変化させる。例えば、スカイダイビングで上空から飛び降りるシーンでは、俳優の目線で、飛ぶ前の上空の飛行機内の映像は前面のスクリーンに投映し、ダイブ中の映像は、下方の街並みを上空から見下ろす映像を床に投映する。飛行機内の映像とダイブ中の映像の両方が前面のスクリーンに投映される場合と異なり、視聴者がダイブ中の映像を見る時は現実世界で重力がかかる方向と映像世界の重力がかかる方向が同じ為、より視聴者が臨場感を感じられるような投映表現を行う事ができる。 In the present invention, a projection direction control signal, which is a signal for switching the projection direction, is incorporated in part of the projection video data in advance at least at the timing of changing the projection direction, and the data is received, The projection direction control signal is analyzed by the discriminating unit, and the optimal reflector position (angle and direction) is controlled according to the video scene and content, thereby changing the video projection direction according to the content of the projection video. For example, in a scene of jumping from the sky in skydiving, the image of the airplane in the sky before the flight is projected on the front screen from the actor's perspective, and the image during the dive is the image of looking down the cityscape below from the sky Project. Unlike the case where both the image in the airplane and the image during the dive are projected on the front screen, when the viewer views the image during the dive, the direction in which gravity is applied in the real world and the direction in which the image world is applied is determined. For the same reason, it is possible to perform a projection expression that makes the viewer feel more realistic.
ここで、本発明の重要な構成要件である投映方向制御信号について、図４（ａ）及び図４（ｂ）を用いて説明する。図４（ａ）では、投映方向制御信号４０４はパルス信号の形態であり、投映方向制御信号を光で検知し受信部で受信する場合の信号波形が記載されている。また、図４（ｂ）には信号化された状態の二種類の投映方向制御信号（４０８及び４０９）が記載されている。このように、光を検知するのではなく、無線通信又は有線通信で送られてきたものを受信してもよい。尚、投映方向を変化させるタイミングでのみ投映方向制御信号が組み込まれている場合は、図４（ａ）や図４（ｂ）に記載されている投映方向制御信号のように、不連続な状態で投映方向制御信号が発せられる事があるが、このタイミングでしか投映方向制御信号を組み込めないわけではない。一周期毎に、投映方向制御信号を組み込み、投映方向制御信号の一つが投映方向を切替えないという意味をもつ信号である場合も含まれる。 Here, the projection direction control signal, which is an important component of the present invention, will be described with reference to FIGS. 4 (a) and 4 (b). In FIG. 4A, the projection direction control signal 404 is in the form of a pulse signal, and the signal waveform when the projection direction control signal is detected by light and received by the receiving unit is described. FIG. 4B shows two types of projection direction control signals (408 and 409) in a signalized state. In this way, instead of detecting light, it may be received that is sent by wireless communication or wired communication. When the projection direction control signal is incorporated only at the timing of changing the projection direction, the discontinuous state as in the projection direction control signal described in FIGS. 4 (a) and 4 (b). In some cases, a projection direction control signal may be issued, but the projection direction control signal cannot be incorporated only at this timing. A case where a projection direction control signal is incorporated every cycle and one of the projection direction control signals has a meaning that the projection direction is not switched is also included.
また、連続した複数の周期の中の複数のパルス信号をまとめて、投映方向制御信号としても良い。この場合、図４（ａ）では、２周期分に含まれる２つのパルス信号を一つの投映方向制御信号とみなせる。このように、連続した複数の周期の中の複数のパルス信号の列から、どういった意味の投映方向制御信号であるかを読み取ってもよい。また、実際は受信状態が良好であるとは限らず、ノイズなどにより受信エラーが起こる可能性もある。こういった受信エラーの発生を防ぐ為、同じ意味を持つ投映方向制御信号が連続して複数回送信される事が望ましい。 Further, a plurality of pulse signals in a plurality of continuous periods may be collected and used as a projection direction control signal. In this case, in FIG. 4A, two pulse signals included in two periods can be regarded as one projection direction control signal. In this way, what the meaning of the projection direction control signal may be read from a sequence of a plurality of pulse signals in a plurality of continuous periods. In addition, the reception state is not always good, and a reception error may occur due to noise or the like. In order to prevent the occurrence of such a reception error, it is desirable that a projection direction control signal having the same meaning is continuously transmitted a plurality of times.
また、投映方向制御信号に対応する命令信号を判別する際、制御テーブルが参照される方法を用いることが出来る。その制御テーブルの一例を図５に示す。図５の参照テーブルによれば、投映方向制御信号がパターン１であると検出された場合、これは映像を右方向へ投映するという意味の信号であり、対応する命令信号は「０００１」であると判別される。そして、判別された命令信号「０００１」が出力されると、映像の投映方向を右側へ切替える様、反射板を駆動する。 Further, when determining a command signal corresponding to the projection direction control signal, a method in which a control table is referred to can be used. An example of the control table is shown in FIG. According to the reference table of FIG. 5, when it is detected that the projection direction control signal is pattern 1, this is a signal meaning that the video is projected in the right direction, and the corresponding command signal is “0001”. Is determined. When the determined command signal “0001” is output, the reflector is driven so as to switch the image projection direction to the right side.
また、投映方向制御信号は、投映方向（上向きに投映する、下向きに投映する、右向きに投映する、など）は示さず、単に方向の切替えを行うタイミングである事を示した信号とする事も可能である。 In addition, the projection direction control signal does not indicate the projection direction (projecting upward, projecting downward, projecting rightward, etc.), but may be a signal indicating that it is the timing for switching the direction. Is possible.
〔実施形態２〕
実施形態２では、受信部、判別部、命令部及び駆動部が、全て投映台に具備されている例であり、図７に示すように駆動部で駆動する反射板７０３が、映像投映装置７０１側ではなく映像投映装置を置く投映台７１０に具備されていて、映像投映装置から投映スクリーン７１１に投映された映像の投映方向を変化させる。

It is provided in the projection stand 710 on which the video projection device is placed instead of the side, and changes the projection direction of the video projected on the projection screen 711 from the video projection device.
尚、本実施形態では、投映台を新たに追加するだけで、投映映像の内容に応じて投映方向を変化させる事に対応していない映像投映装置を用いて、本発明の実施を行う事が可能になる。その為、オプションサービスとしての提供が容易になる。 In this embodiment, the present invention may be implemented using a video projection device that does not support changing the projection direction according to the content of the projected video simply by adding a new projection stand. It becomes possible. Therefore, provision as an optional service becomes easy.
本発明を実施するためには、上述のように、受信部、判別部、命令部、駆動部が必要であるが、それらは必ずしも全ての構成要件が映像投映装置本体内または投映台に配置されている必要は無く、一部の機能が周辺機器（投映スクリーンや電子機器など）に配置されていても構わない。受信部、判別部、駆動部、命令部、駆動部の各々が配置される箇所の組合せの例を図６に示し、以下の実施形態３から実施形態６を用いて説明する。 In order to carry out the present invention, as described above, a receiving unit, a discriminating unit, a command unit, and a driving unit are necessary. However, all the components are not necessarily arranged in the video projection apparatus main body or the projection stand. However, some functions may be arranged in peripheral devices (projection screens, electronic devices, etc.).
