Abstract
An endoscope apparatus includes: a light source that emits white light or narrow-band light; an image sensor having pixels; a color filter including a filter unit having a plurality of filters in which the number of filters for passing green wavelength band light and the number of filters for passing blue wavelength band light satisfy predetermined conditions; a first gain adjustment unit that adjusts a gain of an electric signal generated by the image sensor; a demosaicing processing unit that generates an image signal of a color component passing through a filter based on the electric signal whose gain has been adjusted by the first gain adjustment unit; a color conversion processing unit that performs color separation on an image signal when the light source unit emits the white light; and a second gain adjustment unit that adjusts a gain of each image signal subjected to the color conversion processing.
