Description

上述の目的は、投写面に画像を投写する複数の投写装置を制御する投写制御装置であって、投写面を撮像する撮像装置から取得した画像に基づいて、複数の投写装置のそれぞれの投写領域を取得する取得手段と、複数の投写装置で適用する幾何補正を制御する制御手段と、を備え、制御手段は、取得した画像に基づいて複数の投写装置のうち基準投写装置の投写領域に他の投写装置の投写領域を合致させるように他の投写装置で適用する幾何補正を制御する第１調整処理を実行する場合に、撮像装置が投写面を撮像する前に複数の投写装置のうち他の投写装置で適用されている幾何補正を解除し、基準投写装置で適用されている幾何補正を解除しないことを特徴とする投写制御装置によって達成される。 The above objects, a braking Gosuru projection control a plurality of projection devices for projecting images on a projection surface, based on the image acquired from the imaging device for imaging the projection surface, each of the projection of the plurality of projection devices comprising obtaining means for obtaining an area, and geometric correction control to that control means for applying a plurality of projection equipment, and control means, the reference projection device among the plurality of projection device based on the acquired image When executing the first adjustment process that controls the geometric correction applied by the other projection device so that the projection area of the other projection device matches the projection area , a plurality of projections are performed before the image pickup device images the projection surface. releasing the geometric correction is applied by the device sac Chi another projection device, it is achieved by the projection control apparatus characterized by not releasing the geometric correction is applied the reference projection device.

投写システム１０はさらに、例えばデジタルカメラである撮像装置４００を有する。撮像装置４００は投写面に正対する位置に、投写面の全体を撮影範囲として含むように設置されているものとする。撮像装置４００は直接、あるいはＬＡＮを通じて、ＰＣ２００と通信可能に接続される。ＰＣ２００は、撮像装置４００に予め定められたコマンドを送信することにより、撮像装置４００の動作を制御することができる。例えば撮像装置４００はＰＣ２００からの要求に応じて撮影を行い、得られた画像データをＰＣ２００に送信することができる。 The projection system 10 further includes an image pickup device 400, which is, for example, a digital camera. It is assumed that the image pickup apparatus 400 is installed at a position facing the projection surface so as to include the entire projection surface as a shooting range. The image pickup apparatus 400 is communicably connected to the PC 200 either directly or through a LAN. The PC 200 can control the operation of the image pickup apparatus 400 by transmitting a predetermined command to the image pickup apparatus 400. For example, the image pickup apparatus 400 can take a picture in response to a request from the PC 200 and transmit the obtained image data to the PC 200.

図６は、ＣＰＵ２０１が投写制御アプリケーションプログラムを実行することにより表示部２０５に表示されるＧＵＩ画面６００の例を示す図である。ユーザはＰＣ２００の操作部２０４を通じてＧＵＩ画面６００を操作する。なお、図６（ａ）と図６（ｂ）は、ＧＵＩ画面６００の下側の一部でスタック投写に関する表示を行っている場合と、マルチスクリーン投写に関する表示を行っている場合とを示していること以外は共通である。 FIG. 6 is a diagram showing an example of a GUI screen 600 displayed on the display unit 205 when the CPU 201 executes a projection control application program. The user operates the GUI screen 600 through the operation unit 204 of the PC 200 . Note that FIGS. 6 (a) and 6 (b) show a case where the display related to the stack projection is performed on a part of the lower side of the GUI screen 600 and a case where the display related to the multi-screen projection is performed. It is common except that it is.

なお、ここでは調整対象のプロジェクタの全てについて１つずつ撮影条件を確認する場合について説明するが、調整対象のプロジェクタのうち、ユーザが選択した１つについてだけ撮影条件を確認できるようにしてもよい。この場合、調整対象のプロジェクタの１つを選択するためのＧＵＩ（例えば、リストビュー６０３に表示されているプロジェクタの１つを選択するＧＵＩ）を提供し、選択された１つのプロジェクタに対してのみ、Ｓ１０２１以降の処理を実行すればよい。 Here, it is described a case to check all the one at the photographing conditions to be adjusted projector, but out of adjustment subject to the projector, be allowed to check only photographing conditions for one selected by the user Good. In this case, a GUI for selecting one of the projectors to be adjusted (for example, a GUI for selecting one of the projectors displayed in the list view 603) is provided, and only for the selected one projector. , S1021 and subsequent processes may be executed.

Ｓ１０２５でＣＰＵ２０１は、通信部２０８を通じてコマンドを送信し、撮像装置４００に撮影条件を設定する。例えば既に「撮影条件自動設定」ボタン６０９の操作により、調整対象のプロジェクタそれぞれについての撮影条件が決定されている場合、ＣＰＵ２０１は該当する撮影条件をＲＡＭ２０２から読み出して設定することができる。あるいは、ＣＰＵ２０１は、撮像装置４００をシャッタスピード優先ＡＥモードに設定し、さらに、シャッタスピードをプロジェクタのフレームレートに応じた値に設定してもよい。この場合、シャッタスピードは、例えば、フレームレート［フレーム／秒］の逆数に等しいシャッタスピード（１／フレームレート［秒］）に設定することができる。 In S1025, the CPU 201 transmits a command through the communication unit 208 to set shooting conditions in the image pickup apparatus 400. For example, by already "imaging condition automatic setting" button 60 9 operation, if the imaging conditions for each of the adjusted projector has been determined, CPU 201 can be set by reading the appropriate imaging conditions from the RAM 202. Alternatively, the CPU 201 may set the image pickup apparatus 400 to the shutter speed priority AE mode, and further set the shutter speed to a value corresponding to the frame rate of the projector. In this case, the shutter speed can be set to, for example, a shutter speed (1 / frame rate [seconds]) equal to the reciprocal of the frame rate [frames / second].

「４点指定調整」および「自動形状決定」は、ユーザやＣＰＵ２０１によって予め定められた投写領域に、全てのプロジェクタの投写領域を合致させるキーストーン補正量を自動で決定する処理である。これに対し、「基準プロジェクタに合わせる」は、１つのプロジェクタを基準プロジェクタとして、基準プロジェクタの投写領域に他のプロジェクタの投写領域を合致させるようなキーストーン補正量を自動で決定するモードである。このモードの自動位置合わせが実行されるのは、基準プロジェクタの投写領域の位置が、指定された位置に調整されている場合である。基準プロジェクタ以外のプロジェクタの投写領域を基準プロジェクタの投写領域に合致させるためのキーストーン補正量を自動的に決定する。 "4-point specified adjustment" and "auto contour determining" the projection area predefined by a user or CPU 201, a processing for automatically determining the keystone correction amount to match the projected area of all projectors. On the other hand, "fit to reference projector" is a mode in which one projector is used as a reference projector and a keystone correction amount for matching the projection area of another projector with the projection area of the reference projector is automatically determined. The automatic alignment in this mode is executed when the position of the projection area of the reference projector is adjusted to the specified position. The keystone correction amount for matching the projection area of a projector other than the reference projector with the projection area of the reference projector is automatically determined.
