Imaging apparatus, imaging system, and imaging method

An imaging apparatus includes a first image sensor for receiving light of a first wave range, a second image sensor for receiving light of a second wave range other than the first wave range, an information acquisition unit for acquiring position information relating to the imaging apparatus and environment information relating to an imaging environment of the imaging apparatus, an estimation unit for estimating, for each subject to be imaged by the imaging apparatus, influence of an external factor of the imaging apparatus on a first image, which is obtained from the first image sensor, by using the position information and the environment information that are acquired by the information acquisition unit, and an image synthesis unit configured to synthesize the first image and a second image, which is obtained from the second image sensor, on the basis of the influence estimated by the estimation unit.
