Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a projection apparatus capable of correcting optical characteristics of a projection image without deteriorating the gradation properties, and to provide its control method and control program, and to provide a projection system.SOLUTION: A control section 101 performs correction processing of RAW data, obtained by imaging in an image processing section 104, and also performs development processing on the basis of correction parameters, to produce image data. The control section controls a projection optical system to project a projection image, corresponding to the image data, onto a projection plane.SELECTED DRAWING: Figure 1 【課題】投影画像において階調性を損なうことなく、しかも光学特性の補正を行うことのできる投影装置、その制御方法、および制御プログラム、並びに投影システムを提供する。【解決手段】制御部１０１は、画像処理部１０４によって撮像によって得られたＲＡＷデータを、補正パラメータに基づいて補正処理を行うとともに現像処理を行って画像データとする。制御部は画像データに応じた投影画像を、投影光学系によって投影面に投影する。【選択図】図１
