Title:
A sunshade and an imaging device
Document Type and Number:
Japanese Patent JP6257476
Kind Code:
B2
Abstract:
The invention provides a lens hood and an imaging device in which a lens hood can be reduced in length (size) while light unnecessary to pick up an image is blocked and the blocking of an effective light beam necessary to pick up an image can be minimized. A lens hood (10), which blocks unnecessary light to be incident on a telephoto lens, according to an aspect of the invention includes a first light blocking wall (12) that forms a cylindrical outermost periphery, and a concentric second light blocking wall (14) that partitions an internal space of the first light blocking wall (12) into a plurality of spaces. Each of the first and second light blocking walls (12, 14) is provided in parallel to the traveling direction of an effective light beam used to form a subject image within an angle of view of the telephoto lens, and blocks unnecessary light other than the effective light beam.
