PROBLEM TO BE SOLVED: To acquire an image signal that can achieve both distance measurement over a wide measurement range and distance measurement with high resolution when spatial resolution is maintained.SOLUTION: There is provided an imaging device 1 including: an imaging lens 7 that collects light from a subject A; an imaging element 10 that photographs the light collected by the imaging lens 7 to detect an image signal; and a micro lens array 9 that is arranged at a position to form an actual image formed by the imaging lens 7 into an image on an imaging surface of the imaging element 10, where the micro lens array 9 has two or more types of micro lenses having a focal distance equal to each other and an effective diameter different from each other arranged in array, and the micro lenses each form an image on a plurality of pixels of the imaging element 10.SELECTED DRAWING: Figure 1 |
