Abstract
A solid-state imaging apparatus includes: a solid-state imaging device photoelectrically converting light taken by a lens; and a light shielding member shielding part of light incident on the solid-state imaging device from the lens, wherein an angle made between an edge surface of the light shielding member and an optical axis direction of the lens is larger than an incident angle of light to be incident on an edge portion of the light shielding member.
Claims14
An imaging apparatus, comprising:
- a lens unit having a concentric optical axis;
- an imaging device configured to receive incident light through the lens unit;
- and
- a light shielding member disposed between the imaging device and the lens unit, and configured to shield at least part of the incident light;
- wherein the light shielding member includes an opening,
- wherein a surface of the light shielding member forms an angle “θM” with respect to the concentric optical axis,
- wherein the “θM” is represented by the following formula:
- θM>=arctan [(R+L)/2H]
- wherein R, L, and H represent an effective diameter of the lens unit, a diameter of the opening of the light shielding member, and a distance between the lens unit and the light shielding member, respectively.
