Abstract: An endoscope apparatus includes a light source apparatus including an LED, and an optical filter. The LED, generates, upon supply of a predetermined drive current, light having a peak wavelength at 600 nm as illuminating light to be radiated to a subject, and generates, upon supply of a drive current that is different from the predetermined drive current, light having the peak wavelength shifted to a wavelength that is different from 600 nm. The optical filter is provided on an optical path for the illuminating light, the optical path extending from the LED to an image pickup section configured to receive light from the subject and generate an image pickup signal, and the optical filter is configured to remove light having a wavelength located farther than 595 nm on a wavelength axis in a shifting direction of shifting to a short wavelength, from light on the optical path.
