- the moving mechanism 5 inserts and removes the prism 4 on the optical axis A in the vicinity of the aperture stop S where the light beam height is low. Thereby, the diameter dimensions of the prism 4 and the moving mechanism 5 are small, and the entire imaging device 1 can be made thin.
- the insertion position of the prism 4 is not limited to the vicinity of the brightness stop S, and may be changed as appropriate.
- the frame 5a is fixed to the refractive surface 4b of the prism 4, and constitutes a diaphragm having an opening 5c formed in a portion corresponding to the central portion of the prism 4. .

Since light is incident on the system 2, it is possible to acquire a perspective image of the visual field obliquely forward of the objective optical system 2.

- the focal point moves in the direction close to the objective optical system 2 by the positive power of the refractive surface 4b. That is, according to the present embodiment, the focal point shift caused by the insertion of the prism 4 is corrected by the positive power of the refracting surface 4b, and the focal point moves away from the direct view observation state to the perspective observation state.

Therefore, by reducing the size of the opening 5c in the tilt direction D in which asymmetric aberration occurs, the amount of asymmetric aberration generated can be reduced, and a perspective image with good image quality can be obtained.
- the refracting surface 4b of the prism 4 has a positive power.

- the first group G1, the second group G2, and the third group G3 are held in cylindrical lens frames 61, 62, and 63 that are separate from each other. Both end portions of the lens frame 63 that holds the third group G3 are nested in the end portions of the lens frames 61 and 62 that hold the first group G1 and the second group G2, and the lens frame 63 is The lens frames 61 and 62 are movable in the direction of the optical axis A. Thereby, by the movement of the lens frame 63, the position of the third group G3 with respect to the first group G1 and the second group G2 can be adjusted, and the focal point can be adjusted in the direction of the optical axis A.
- the focus shift due to the insertion of the prism 4 is corrected by the positive power of the refractive surface 4b.
- the focus tolerance in the perspective observation state is finally adjusted by fine adjustment of the position of the prism 4 in the optical axis A direction, and then the lens frame 63 is fixed to the lens frames 61 and 62, whereby the dimensional tolerance of the prism 4 is obtained. It is possible to easily and surely obtain a high focus accuracy that is difficult to achieve only by improving the lens.
- a mask process for superimposing a visual field mask having an opening may be applied to the direct-view image and the perspective image, and the mask-processed image may be displayed on the display.
- the imaging apparatus 1 uses a general visual field mask having an octagonal opening for the direct-view image X, and a diagram for the perspective image Y.

- the objective optical system 2 having a half field angle of about 65 ° is used, and the observation direction is inclined downward by 15 ° with respect to the direct viewing direction.
- the angle of view is 80 ° (actually in the lower right part and the lower left part).
- the angle of view becomes approximately 90 ° due to the influence of the distortion, and the image is missing at the lower right portion and the lower left portion in the perspective image Y.
- the field of view as a whole becomes asymmetrical in the vertical direction. Therefore, the perspective image Y that does not give the viewer a sense of incongruity can be displayed by concealing the missing part of the image using a field mask having a small circular opening.
- the prism 4 may be provided to be rotatable about the optical axis A at the insertion position.
- the direction of the optical axis A on the incident side deflected by the deflecting surface 4a changes, and the observation direction changes.
- the observable range can be expanded. For example, in FIG. 2, a diagonally downward visual field is observed on the paper surface, but when the prism 4 is rotated by 90 °, an obliquely horizontal field of view is observed, and when the prism 4 is rotated by 180 °, an obliquely upward visual field is observed. be able to. Further, by continuously rotating the prism 4, it is possible to look around the visual field at the time of direct viewing.

Abstract
Description
本発明は、上述した事情に鑑みてなされたものであって、観察方向を直視と斜視との間で切り替え可能としつつ、焦点が適切な位置に合った画像を取得することができる撮像装置を提供することを目的とする。
本発明の一態様は、物体の光学像を形成する対物光学系と、該対物光学系によって形成された光学像を撮影する撮像素子と、前記対物光学系の光軸の途中位置に挿脱される光学部材と、該光学部材を、前記対物光学系の光軸上の第1の位置と該光軸から外れた第2の位置との間で移動させる移動機構とを備え、前記光学部材が、前記対物光学系の光軸を偏向する偏向面と、パワーを有する屈折面とを有する撮像装置である。
このようにすることで、光学部材の光軸上への挿入によって発生する焦点の物体側へのずれが、屈折面の正のパワーによって相殺される。したがって、斜視観察において、対物光学系の手前側に焦点の合った画像を取得することができる。
上記態様においては、前記光学部材が、前記光軸に沿って互いに対向配置される2つの面を有し、これら2つの面のうち、一方が前記偏向面であり、他方が前記屈折面であってもよい。
このようにすることで、光学部材の形状を簡易にすることができる。
このようにすることで、光学部材の形状を簡易にすることができる。
このようにすることで、対物光学系の光軸に挿入された光学部材によって収差が発生し、特に偏向面による前記光軸の偏向方向において非対称収差が発生する。そこで、絞りの開口の寸法を、前記偏向方向において小さくすることによって、非対称収差の発生を効果的に抑制することができる。
本実施形態に係る撮像装置1は、図1および図2に示されるように、物体の光学像を形成する対物光学系2と、対物光学系2によって形成された光学像を撮影する撮像素子3と、楔形のプリズム(光学部材)4と、該プリズム4を対物光学系2の光軸A上に挿脱する移動機構5とを備えている。なお、図1、図2および図9においては、図が煩雑になることを避けるために、移動機構5の構成のうち枠5a(後述)のみを図示している。
また、挿入位置に配されたときの枠5aと偏向面4aとの相対的な向きに応じて、枠5aに形成される開口5cの短軸の方向C1は、適宜変更される。例えば、図1において、傾斜方向Dが、奥行き方向(紙面に垂直な方向)である場合には、開口5cは、図8に示されるように、図3Aに対して90°回転する必要がある。
本実施形態に係る撮像装置1によれば、移動機構5によってプリズム4の位置を退避位置と挿入位置との間で変更することによって、観察方向を、直視と斜視との間で変更することができる。
このようにすることで、直視観察状態から斜視観察状態に切り替えたときに、焦点がより遠くへ移動する。したがって、遠くに位置する対象を斜視観察する用途においては、このようにすることで、観察対象が鮮明に撮影された斜視画像を取得することができる。
そこで、像が欠けた部分を、小さい円形の開口部を有する視野マスクを使用して隠すことによって、観察者に違和感を与えない斜視画像Yを表示することができる。
プリズム4が光軸Aを中心に回転することによって、偏向面4aによって偏向されている入射側の光軸Aの向きが変化し、観察方向が変化する。これにより、観察可能な範囲を拡大することができる。例えば、図2においては、紙面において斜め下方の視野が観察されるが、プリズム4を90°回転したときには、斜め左右方向の視野を、180°回転したときには、斜め上方の視野を、それぞれ観察することができる。また、プリズム4を連続的に回転させることによって、直視のときの視野の周辺を見回すことができる。
この場合には、プリズム4の光軸Aへの挿入に因る焦点のずれを補正することはできないが、偏向面4aによって発生する非点収差を効果的に抑制し、画質の良好な斜視画像を取得することができる。
