Claim 14:
15. A processing apparatus comprising:
a processor, wherein
the processor is configured to execute:
controlling a light source apparatus to switch light between first illumination light in which a plurality of kinds of light with different center wavelengths are emitted at a first light amount ratio and second illumination light in which the plurality of kinds of light are emitted at a second light amount ratio different from the first light amount ratio;
generating a first image signal based on an image pickup signal obtained by picking up an image of a subject illuminated with the first illumination light;
generating a second image signal based on an image pickup signal obtained by picking up an image of the subject illuminated with the second illumination light; and
generating a corrected image signal in which color is enhanced based on the first image signal and the second image signal, and
the second illumination light is light obtained by adjusting the second light amount ratio so that the second image signal related to a reference portion of the subject indicates achromatic color within a predetermined error range.
