    Abstract: An endoscope device includes: an image sensor that has a first color filter and a second color filter and that acquires a first image signal based on a first light transmitted through the first color filter and a second image signal based on a second light transmitted through the second color filter; and one or more processors configured to: perform color separation processing and individual-difference correction processing; and respectively allocate the first and second image signals after the processings being performed to first and second channels of a color image signal. The color separation processing is processing in which the second and first light are subtracted from the first and second image signals, respectively. The individual-difference correction processing is processing in which, for each image signals, an error is corrected based on the difference in spectral characteristics between the color filter and a reference color filter.
