Abstract: A light detecting device is provided with: a filter array including filters arranged two-dimensionally, each of the filters having a light-incident surface and a light-emitting surface, the filters including multiple types of filters having mutually different transmission spectra; and an image sensor having a light-detecting surface facing the light-emitting surface, the image sensor being provided with light-detecting elements arranged two-dimensionally on the light-detecting surface, wherein the distance between the light-emitting surface and the light-detecting surface is different for each of the filters.
