The present invention relates to an imaging device including a multi-lens including a central optical system (wide-angle lens) and an annular optical system (telescopic lens) which have a common optical axis, an image sensor, and an array lens provided on the incidence surface side of the image sensor and including microlenses (pupil imaging lens). In a preferred aspect of the present invention, two images having different characteristics are generated based on a pupil image of each unit block including 3×3 light reception cells assigned to each of the microlenses of the array lens. The unit block has eight surrounding light reception cells that correspond to one of the two images, and the eight surrounding light reception cells in the unit block are configured to output RGB pixel signals in all wavelength regions necessary for generating this one image.
