| 1. A captured image data processing method comprising:
subtracting, from a pixel value of a second image data acquired by way of an imaging process causing a first light source
to emit light, a pixel value of a corresponding pixel of first image data acquired by way of an imaging process causing the
first light source not to emit light;
obtaining difference image data corresponding to an image captured in an irradiation environment of only the first light source
based on the subtraction;
performing a white balance adjustment process on the difference image data;
adding pixel values of pixels in the difference image data to corresponding pixel values of the first image data; and
generating a final pixel value adjustment image based on the addition of the difference image data and the first image data.
