1. An imaging apparatus comprising: an imaging element comprising an imaging plane in which pixels to convert light into electric signals are arranged;
a photographing optical system that forms a subject image of a first projection system on the imaging plane; and, a processor executing instruction to implement:
an imaging control section that acquires first projection images corresponding to the subject image by the imaging element;
a first projection converting section that converts the first projection images into second projection images, respectively, each of which is an image of a second projection system in which a variation of a change amount of an image height on the imaging plane to a change amount of an entrance angle of the light into the photographing optical system is smaller than that of the first projection image;
a second projection converting section that converts the composed image into an image of a projection system different, from the second projection system.
