An endoscope device comprises: an illumination means for, within a prescribed time, carrying out an illumination by an illumination light of a first band, and carrying out an illumination by a an illumination light of a second band over a first number of iterations which is greater than one; a brightness computation means for computing a first brightness by a color conversion matrix process which uses a first image capture signal on the basis of the illumination by the illumination light of the first band and a second image capture signal on the basis of the illumination of a first prescribed iteration among the first number of iterations, and for computing a second brightness by a color conversion matrix process which uses the first image capture signal on the basis of the illumination by the illumination light of the first band and a second image capture signal on the basis of the illumination of other than the first prescribed iteration among the first number of iterations; and a compositing means for mult
