Abstract
An imaging device may generate a zoom image corresponding to a plurality of magnifications by adjusting an effective focal length through a multi-layer optical system including an active imaging array having an active imaging lens.
Claims20
An imaging device comprising:
- a plurality of imaging lens arrays comprising a plurality of imaging optical lenses;
- and
- a sensing array comprising a plurality of sensing elements configured to sense light passing through the plurality of imaging lens arrays,
- wherein a first imaging lens array and a second imaging lens array among the plurality of imaging lens arrays comprise an active imaging lens with a variable focal length, and a third imaging lens array among the plurality of imaging lens arrays comprises a passive imaging lens with a fixed focal length,
- wherein each of the first imaging lens array, the second imaging lens array and the third imaging lens array are spaced apart from the sensing array, wherein each of the first imaging lens array, the second imaging lens array and the third imaging lens array are separated from each other, and
- wherein distances between the first imaging lens array, the second imaging lens array and the third imaging lens array on an optical axis are fixed.
