Imaging apparatus, imaging method, and recording medium

An imaging method comprising:

• an imaging step of sequentially outputting, by an imaging unit, a first frame image and a second frame image, the first frame image and the second frame image being obtained by continuously capturing an optical image incident through an imaging optical system;
• a first image processing step of executing, by a first image processing unit, image processing on image data of a first region of each frame image output by the imaging unit;
• a second image processing step of executing, by a second image processing unit, image processing on image data of a second region of the each frame image output by the imaging unit;
• and
• an image combining step of combining, by an image combining unit, the image data of the first region processed by the first image processing unit and the image data of the second region processed by the second image processing unit, wherein
• a time required for the image processing per frame image is longer in the second image processing step than in the first image processing step, and
• in the image combining step, a result of executing the image processing on the second frame image by the first image processing unit and a result of executing the image processing on the first frame image by the second image processing unit are combined to generate a corrected frame image.
