IMAGE PICK-UP DEVICE, AND IMAGING APPARATUS

PROBLEM TO BE SOLVED: To provide an imaging apparatus having an optical system in which an angle of principal ray incidence on an image pick-up device largely changes, and capable of improving optical characteristics.SOLUTION: In an imaging apparatus includes an optical unit in which incident angle of a light beam on an image pick-up device varies depending on zoom position, for a principal ray which may incident on another neighboring pixel when the incident angle θb of a light beam from the optical unit to an image pick-up device 3010 changes depending on the change of zoom magnification of the optical unit, a projection 3005-1 is formed on the upper plane of an optical waveguide so as to have a wide projection area on the upper plane of an optical waveguide 3006 of an image pick-up device.SELECTED DRAWING: Figure 3 【課題】撮像素子への主光線入射角度が大きく変化する光学系を有する撮像装置において、光学特性の改善した撮像装置を提供する。【解決手段】撮像素子への光の入射角度がズーム位置により異なる光学部を搭載する撮像装置において、光学部のズーム倍率の変更により、光学部から撮像素子３０１０への光の入射角度θｂが変化する場合に隣接する別の画素への光が入射することが想定される主光線に対し、撮像素子の導波路３００６上面の投影面積が広くなるよう、導波路上面に突起部３００５−１を設けた。【選択図】図３
