Claim Text:
1. An image capturing module comprising: a microlens array that collects light from a subject which is imaged at an image plane; a filter that allows light in specific wavelength bands in the light collected by the microlens array to pass therethrough; and an image capturing device that acquires images of the light passing through the filter, wherein the filter is formed by arraying a plurality of RGB filter portions that pass light in RGB wavelength bands and a plurality of narrow-band filter portions that pass light in wavelength bands that are narrower than the RGB wavelength bands, wherein the image capturing device includes a plurality of color-wavelength obtaining regions that acquire images of the light passing through the plurality of RGB filter portions and a plurality of narrow-band-wavelength obtaining regions that acquire images of the light passing through the plurality of narrow-band filter portions, wherein the microlens array includes a plurality of first microlenses that are disposed in correspondence with the respective plurality of color-wavelength obtaining regions and a plurality of second microlenses that are disposed in correspondence with the respective plurality of narrow-band-wavelength obtaining regions, and wherein the plurality of first microlenses are each disposed so that the light from the subject imaged at the image plane reaches at least one of the plurality of color-wavelength obtaining regions, wherein in the image capturing device, a plurality of image-capturing region units are two dimensionally arrayed, wherein each of the plurality of image-capturing region units includes one of the plurality of color-wavelength obtaining regions and (n wherein the plurality of first microlenses and the plurality of second microlenses are arrayed with a ratio of 1:(n
