1. An imaging apparatus comprising:
a first image sensor configured to receive light of a first wave range;
a second image sensor configured to receive light of a second wave range other than the first wave range;
an information acquisition unit configured to (A) acquire (1) position information relating to the imaging apparatus, (2) environment information relating to an imaging environment of the imaging apparatus, and (3) map information relating to a position of the imaging apparatus, and (B) generate, based on the position information and the map information, information on each subject to be imaged;
an estimation unit configured to (A) determine, for each subject to be imaged by the imaging apparatus, an area that generates mist in an image imaged by the imaging apparatus, and (B) estimate, based on the determined area, influence of generation of mist on a first image, which is obtained from the first image sensor, by using (1) the position information, (2) the environment information, and (3) the information on each subject to be imaged; 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,
wherein the information acquisition unit corrects the position information on the basis of pattern matching using (1) the first image and apparatus information of the imaging apparatus including the position information and imaging direction information or (2) the second image and the apparatus information of the imaging apparatus.
