To make it possible, in the case of performing division imaging on a subject while changing a posture of an imaging apparatus, to execute the imaging so that ranges in focus overlap with each other even when the planar subject has a shape including curvature or distortion.SOLUTION: An information processor 100 sets an imaging apparatus 1's posture for performing division imaging on a subject 3. A posture calculation unit 503 calculates a second posture of the imaging apparatus 1 that satisfies a prescribed condition with respect to a previously determined first posture of the imaging apparatus 1. On the basis of shape information on the subject 3, an in-depth-of-field imaging range calculation unit 504 calculates an in-depth-of-field imaging range within an imaging enabled range in the second posture calculated by the posture calculation unit 503. A posture correction unit 505 corrects the second posture calculated by the posture calculation unit 503 so that the in-depth-of-field imaging range in the second posture calculated by the in-depth-of-field imaging range calculation unit 504 overlaps with an in-depth-of-field imaging range in the first posture.SELECTED DRAWING: Figure 5 【課題】撮像装置の姿勢を変更しながら被写体を分割撮影する場合に、例えば平面状をなす被写体がたわみや歪みを含んだ形状をしているときにも、ピントの合った範囲が相互に重なるようにして撮影を実行できるようにする。【解決手段】情報処理装置１００は、被写体３を分割撮影するための撮像装置１の姿勢を設定する。姿勢算出部５０３は、撮像装置１の既に決まった第１の姿勢に対して所定の条件を満たす撮像装置１の第２の姿勢を算出する。被写界深度内撮影範囲算出部５０４は、被写体３の形状情報に基づいて、姿勢算出部５０３で算出した第２の姿勢での撮影可能範囲の中で被写界深度内撮影範囲を算出する。姿勢補正部５０５は、被写界深度内撮影範囲算出部５０４で算出した第２の姿勢での被写界深度内撮影範囲が、第１の姿勢での被写界深度内撮影範囲に重なるように、姿勢算出部５０３で算出した第２の姿勢を補正する。【選択図】図５
