1. An image processing device, comprising:
circuitry configured to:
correct pupil division pixel signals of pupil division pixels to correct an inter-pixel sensitivity difference between the pupil division pixels;
add the corrected pupil division pixel signals pupil units of the pupil division pixels with different addition patterns;
generate, based on the added pupil division pixel signals, respective pixel addition images for the different addition patterns; and
generate, based on the generated pixel addition images, an output image with a resolution higher than resolutions of the generated pixel addition images.
