Abstract
(EN) The present invention provides an optical member provided with a plurality of opening regions, and an imaging device. This optical member is provided with a plurality of opening regions including a first opening region and a second opening region which each transmit a light ray of an optical system, the first opening region and the second opening region being adjacent to each other. The optical member comprises: a plurality of optical filters (144B, 144C) that are disposed in the first opening region and the second opening region, and transmit light having wavelength bands at least partially different from each other; a plurality of polarizing filters (148B, 148C) that are disposed in the first opening region and the second opening region, and have polarization directions different from each other; and a light ray incidence reduction part (W) that reduces the incidence of a light ray (U) incident on the first opening region on the optical filter (144C) and/or polarizing filter (148C) disposed in the second opening region.
(FR) La présente invention concerne un élément optique comportant une pluralité de régions d'ouverture, ainsi qu'un dispositif d'imagerie. Cet élément optique est pourvu d'une pluralité de régions d'ouverture comprenant une première région d'ouverture et une seconde région d'ouverture qui transmettent chacune un rayon lumineux d'un système optique, la première région d'ouverture et la seconde région d'ouverture étant adjacentes l'une à l'autre. L'élément optique comprend : une pluralité de filtres optiques (144B, 144C) qui sont disposés dans la première région d'ouverture et la seconde région d'ouverture et transmettent une lumière ayant des bandes de longueur d'onde au moins partiellement différentes les unes des autres ; une pluralité de filtres de polarisation (148B, 148C) qui sont disposés dans la première région d'ouverture et la seconde région d'ouverture et ont des directions de polarisation différentes l'une de l'autre ; et une partie de réduction d'incidence de rayon lumineux (W) qui réduit l'incidence d'un rayon lumineux (U) incident sur la première région d'ouverture sur le filtre optique (144C) et/ou le filtre de polarisation (148C) disposé(s) dans la seconde région d'ouverture.
(JA) 複数の開口領域を備える光学部材及び撮像装置を提供する。光学部材は、光学系の光線を透過させる、第1開口領域及び第2開口領域を含む複数の開口領域を備え、第1開口領域と第2開口領域とは互いに隣接しており、第1開口領域及び第2開口領域に配置され、少なくとも一部の波長帯域がそれぞれ異なる光を透過させる複数の光学フィルタ(144B、144C)と、第1開口領域及び第2開口領域に配置され、偏光方向が互いに異なる複数の偏光フィルタ(148B、148C)と、第1開口領域に入射した光線(U)が、第2開口領域に配置された光学フィルタ(144C)及び偏光フィルタ(148C)のうち少なくとも一方に入射することを低減する光線入射低減部(W)と、を備える。
