Description
(3)上記インタラクティブプロジェクターにおいて、前記キャリブレーション実行部は、前記撮像されたオートキャリブレーション画像内の明度を調べる際に、前記撮像されたオートキャリブレーション画像の周縁に存在する一部の領域を除外し、除外した領域以外の中央領域における明度を調べるものとしてもよい。
この構成によれば、環境光の影響が少ない中央領域の明度が許容範囲内に収まるように露出の調整を行うので、適切な露出調整を行うことが可能である。
(3) In the interactive projector, the calibration execution unit excludes a part of a region existing at a periphery of the captured auto-calibration image when examining the brightness in the captured auto-calibration image. The brightness in the central area other than the excluded area may be examined.
According to this configuration, the exposure adjustment is performed so that the brightness of the central region that is less affected by the ambient light is within the allowable range.
プロジェクター100は、投写スクリーン面SS上に投写画面PS(Projected Screen)を投写する。投写画面PSは、通常は、プロジェクター100内で描画された画像を含んでいる。プロジェクター100内で描画された画像がない場合には、プロジェクター100から投写画面PSに光が照射されて、白色画像が表示される。本明細書において、「投写スクリーン面SS」とは、画像が投写される部材の表面を意味する。また、「投写画面PS」とは、プロジェクター100によって投写スクリーン面SS上に投写された画像の領域を意味する。通常は、投写スクリーン面SSの一部に投写画面PSが投写される。投写スクリーン面SSを「投写面SS」とも呼ぶ。 The projector 100 projects a projection screen PS (Projected Screen) on the projection screen surface SS. The projection screen PS usually includes an image drawn in the projector 100. When there is no image drawn in the projector 100, light is emitted from the projector 100 to the projection screen PS, and a white image is displayed. In this specification, “projection screen surface SS” means the surface of a member on which an image is projected. The “projection screen PS” means an area of an image projected on the projection screen surface SS by the projector 100. Usually, the projection screen PS is projected on a part of the projection screen surface SS. The projection screen surface SS is also referred to as a “projection surface SS”.
図6のステップS130に示した例では、撮像されたオートキャリブレーション画像ACPのうちで、左右の両端部の領域をそれぞれ除外しているが、この代わりに、上端部の領域と下端部の領域とをそれぞれ除外しても良い。或いは、左右の両端部の領域に加えて、上下の両端部の領域も除外しても良い。また、図6の例では、除外した左端部と右端部の領域のサイズは、撮像されたオートキャリブレーション画像ACPの幅のそれぞれ約1/3であり、残った中央領域の幅も撮像されたオートキャリブレーション画像ACPの幅の約1/3となっているが、除外する領域のサイズは適宜好ましい値に設定可能である。これらの説明から理解できるように、明度を調べる際には、撮像されたオートキャリブレーション画像ACPの周縁に存在する一部の領域を除外し、除外した領域以外の中央領域における明度を調べることが好ましい。但し、周縁の領域を除外せずに、撮像されたオートキャリブレーション画像ACPの全体を明度の調査対象としても良い。 In the example shown in step S130 of FIG. 6, the left and right end regions are excluded from the captured auto-calibration image ACP. Instead, the upper end region and the lower end region are excluded. And may be respectively excluded. Alternatively, the upper and lower end regions may be excluded in addition to the left and right end portions. In the example of FIG. 6, the size of the excluded left end portion and right end portion area is about 1/3 of the width of the captured auto-calibration image ACP, and the width of the remaining central region is also imaged. Although it is about 1/3 of the width of the auto calibration image ACP, the size of the area to be excluded can be set to a preferable value as appropriate. As can be understood from these explanations, when examining the brightness, a part of the area existing at the periphery of the captured auto-calibration image ACP is excluded, and the brightness in the central area other than the excluded area is examined. preferable. However, the entire captured auto-calibration image ACP may be the lightness investigation target without excluding the peripheral region.
