Abstract
An imaging apparatus that forms an image of a light beam transmitted through an imaging lens on an imaging element includes a laminated material that is provided on the imaging element, the light beam being transmitted through the laminated material, the laminated material being provided at a position at which an end portion of an upper surface of the laminated material allows an outermost light beam out of light beams to be transmitted therethrough, the light beams entering a pixel in an outer end portion of the imaging element in an effective pixel area, the position having a width Hopt.
Claims20
An imaging apparatus, comprising:
- an imaging lens;
- an imaging element configured to receive incident light including a plurality of light beams in an effective pixel area;
- and
- a laminated material disposed on the imaging element, wherein
- a distance Hopt between an outer edge of the imaging element and an outer edge of an upper surface of the laminated material is represented by the following formula:
- Hopt=T*(f−2*H*Fno)/(2*f*Fno+H)
- wherein T, f, Fno, and H represent a thickness of the laminated material, a focal length of the imaging lens, an F-number of the imaging lens, and an image height of the image sensor, respectively.
A camera system, comprising:
- an imaging apparatus, including:
- an imaging lens,
- an imaging element configured to receive incident light including a plurality of light beams in an effective pixel area, and
- a laminated material disposed on the imaging element, wherein
- a distance Hopt between an outer edge of the imaging element and an outer edge of an upper surface of the laminated material is represented by the following formula:
- Hopt=T*(f−2*H*Fno)/(2*f*Fno+H)
- wherein T, f, Fno, and H represent a thickness of the laminated material, a focal length of the imaging lens, an F-number of the imaging lens, and an image height of the image sensor, respectively.
