PROBLEM TO BE SOLVED: To create an excellent composite image having a high symmetry of a composited subject image even though centroid positions of respective PSFs of a plurality of imaging systems are deviated from each other during compositing a plurality of images acquired by using the plurality of imaging systems.SOLUTION: An image processing device 20 performs correction processing for reducing positional deviation of a subject image between a plurality of first images to the plurality of first images acquired by using a plurality of imaging systems 100 for imaging the same subject, and composites a plurality of second images in which the positional deviation of the subject images is reduced by performing the correction processing to create a composite image. The correction processing includes: first correction processing for reducing positional deviation of the subject images corresponding to parallax included in the plurality of first images; and second correction processing for reducing positional deviation of the subject images corresponding to difference of centroid positions of the plurality of imaging systems by using information on centroid positions of respective point image distribution functions of the plurality of imaging systems.SELECTED DRAWING: Figure 8 【課題】複数の撮像系を用いて取得された複数の画像を合成する際に該複数の撮像系のそれぞれのＰＳＦの重心位置が互いにずれていても、合成された被写体像の対称性が高い良好な合成画像を生成する。【解決手段】画像処理装置２０は、同一の被写体を撮像する複数の撮像系１００を用いて取得された複数の第１の画像に対して、複数の第１の画像間での被写体像の位置ずれを低減する補正処理を行い、補正処理が行われることで被写体像の位置ずれが低減された複数の第２の画像を合成して合成画像を生成する。補正処理は、複数の第１の画像に含まれる視差に応じた被写体像の位置ずれを低減する第１の補正処理と、複数の撮像系のそれぞれの点像分布関数の重心位置に関する情報を用いて、複数の撮像系の重心位置の相違に応じた被写体像の位置ずれを低減する第２の補正処理とを含む。【選択図】図８
