＜実施の形態の詳細＞
　以下、本発明の第１の実施の形態による構造体について、図面を参照しながら説明する。 <Details of the embodiment>
Hereinafter, a structure according to a first embodiment of the present invention will be described with reference to the drawings.
＜概要＞
　本発明の電子機器は、例えば、デジタルカメラ、スマートフォン、無人移動体（無人飛行体：Unmanned aerial vehicle, UAV）、車載カメラ等、撮影部（カメラ）を備えた機器であるがこれに限られず。カメラを搭載可能なすべての電子機器を含む。 <Overview>
The electronic device of the present invention is, for example, a device including a photographing unit (camera) such as a digital camera, a smartphone, an unmanned moving body (Unmanned aerial vehicle, UAV), an in-vehicle camera, but is not limited thereto. Includes all electronic devices that can be equipped with cameras.
　図１に示されるように、本実施の形態による電子機器３００は撮影部１０が取り付けられている。撮影部１０は、円偏光フィルタ（サーキュラーＰＬフィルタ）１０２と、レンズ１０４と、受光素子１０６と、駆動部２０２と、制御部２０４とを備えている。なお、図１は説明を容易にするために、それぞれの要素の外形、位置関係は簡素化して示している。 As shown in FIG. 1, an electronic device 300 according to the present embodiment has a photographing unit 10 attached thereto. The imaging unit 10 includes a circular polarization filter (circular PL filter) 102, a lens 104, a light receiving element 106, a driving unit 202, and a control unit 204. Note that FIG. 1 shows the outline and positional relationship of each element in a simplified manner for easy explanation.
　図２に示されるように、本実施の形態による制御部２０４は、少なくとも方向取得部と、位置取得部と、記憶部と、制御部とを備えている。 As shown in FIG. 2, the control unit 204 according to the present embodiment includes at least a direction acquisition unit, a position acquisition unit, a storage unit, and a control unit.
　方向取得部は、少なくとも撮影部１０の撮影方向（光軸方向）を取得するものであり、例えば、電子コンパス等を採用することができる。電子コンパスは、少なくともパン方向の角度を検出することができるものである。 The direction acquisition unit acquires at least the shooting direction (optical axis direction) of the shooting unit 10, and an electronic compass or the like can be employed, for example. The electronic compass can detect at least an angle in the pan direction.
　位置取得部は、電子機器３００の位置（位置情報）を取得するものであり、ＧＰＳ（Global Positioning System, GPS）機能を有する。位置取得部は、当該電子機器の位置と、上述した撮影方向と、現在時刻とに基づいて算出された現在の太陽の位置及び方角を取得する。 The position acquisition unit acquires the position (position information) of the electronic device 300, and has a GPS (Global Positioning System, GPS) function. The position acquisition unit acquires the current position and direction of the sun calculated based on the position of the electronic device, the shooting direction described above, and the current time.
　制御部２０４は、少なくとも電子機器３００の位置又は撮影方向Ｄ（図１参照）と、太陽の位置との相対的な位置関係・方向関係に基づいて円偏光フィルタ１０２の偏光の強度を調整・制御する（制御の仕方は後述する）。なお、本実施の形態による制御部２０４は、撮影部１０のパン方向（Ｚ方向と回転軸都市、ＸＹ平面に沿った回転方向）の変位に基づいて偏光を制御する。 The control unit 204 adjusts / controls the intensity of the polarization of the circularly polarizing filter 102 based on at least the position or shooting direction D (see FIG. 1) of the electronic device 300 and the relative positional relationship / directional relationship between the sun and the sun. (The method of control will be described later). The control unit 204 according to the present embodiment controls the polarization based on the displacement of the photographing unit 10 in the pan direction (Z direction, rotation axis city, and rotation direction along the XY plane).
　記憶部は、ある時点（初期位置）における撮影方向と電子機器の位置と、太陽の位置と、偏光の強度（詳しくは後述する）を記憶する。 The storage unit stores the photographing direction at a certain point in time (initial position), the position of the electronic device, the position of the sun, and the intensity of polarized light (described in detail later).
　図３に示されるように、本実施の形態による円偏光フィルタ１０２は、少なくとも、偏光板１１０と、偏光板の光軸に対するロール角を調整するための調整リング１１２とを有している。本実施の形態による偏光板１１０は、その内部の結晶構造が同一方向に並んでいるため、当該結晶方向に一致した振幅成分の光しか透過しない性質を持ったものである。 As shown in FIG. 3, the circularly polarizing filter 102 according to the present embodiment has at least a polarizing plate 110 and an adjusting ring 112 for adjusting the roll angle with respect to the optical axis of the polarizing plate. The polarizing plate 110 according to the present embodiment has a property of transmitting only light having an amplitude component that matches the crystal direction because the internal crystal structure is aligned in the same direction.
　駆動部２０２は、アクチュエータ２０６を有している。アクチュエータ２０６は、制御部２０４からの制御信号によって、調整リング１１２を回転させることにより、偏光の強度を調整する。 The driving unit 202 has an actuator 206. The actuator 206 adjusts the intensity of polarized light by rotating the adjustment ring 112 according to a control signal from the control unit 204.
　図３乃至図６を参照して実際の使用方法を説明する。使用者は、撮影部１０による画像を図示しない表示部によって確認し、調整リング１１２を手動操作して偏光の強度を調整する（ステップＳ６０２：初期位置）。この時、使用者によって設定保持の操作がなされると、撮影部１０の方向（撮影方向）と太陽の位置と調整リングの位置（＝偏光強度）が記憶部に記憶される（ステップＳ６０４）。使用者が撮影部１０の向きを変えたり、移動等することによって撮影場所を変更するなどして、初期位置からの変位を測位した場合（ステップＳ６０６）、制御部１０は、方向取得部と、位置取得部と、記憶部とから必要な情報を取得し、撮影部１０のパン方向における回転方向θ１に基づいて、調整リング１１２の回転方向θ２を自動で制御する（ステップ６０８）。 The actual usage will be described with reference to FIGS. The user confirms the image by the photographing unit 10 with a display unit (not shown), and manually operates the adjustment ring 112 to adjust the intensity of polarized light (step S602: initial position). At this time, when the setting operation is performed by the user, the direction of the imaging unit 10 (imaging direction), the position of the sun, and the position of the adjustment ring (= polarization intensity) are stored in the storage unit (step S604). When the user changes the position from the initial position by changing the direction of the photographing unit 10 or moving the photographing unit 10 (step S606), the control unit 10 includes a direction obtaining unit, a position acquiring unit, acquires necessary information from the storage unit, based on the rotation direction theta 1 in the pan direction of the imaging unit 10, controls the rotation direction theta 2 of the adjusting ring 112 automatically (step 608).
　このように、本実施の形態によれば、撮影部の方向に応じて、最適な偏光強度を自動で制御することができるため、特に、陸上又は空中を遠隔操作によって移動可能に構成されている移動体等に撮影部が搭載された場合において、当該移動体の向き（撮影部１０の向き）や位置に応じて、最適な偏光状態の画像を撮影することができる。 As described above, according to the present embodiment, the optimum polarization intensity can be automatically controlled according to the direction of the photographing unit, and therefore, it is particularly configured to be movable on land or in the air by remote control. When an imaging unit is mounted on a moving body or the like, an image with an optimal polarization state can be captured in accordance with the direction of the moving body (the direction of the imaging unit 10) and the position.
　図７は、空中を遠隔で操作可な能飛行体４００に、本実施の形態による撮影部１０を取り付けた図を示している。撮影部１０は、飛行体の本体部とジンバル（図示せず）で接続されている。そのため、撮影部１０の撮影方向（θ１）と、飛行体４００の移動方向（θ３）とは独立して制御可能に構成されている。このような場合であっても、本実施の形態によれば、飛行体が飛行中に撮影した画像の偏光強度は、初期位置にて一度設定した偏光強度を維持することができる。 FIG. 7 shows a view in which the photographing unit 10 according to the present embodiment is attached to an ability flying body 400 that can be remotely operated in the air. The imaging unit 10 is connected to the main body of the flying object by a gimbal (not shown). Therefore, the imaging direction (θ 1 ) of the imaging unit 10 and the moving direction (θ 3 ) of the flying object 400 can be controlled independently. Even in such a case, according to the present embodiment, the polarization intensity of the image captured by the flying object during the flight can maintain the polarization intensity once set at the initial position.
　図７に示されるような飛行体４００に本発明を適用した場合、一般的な撮影用途（静止画・動画を問わない）の他、測量、橋梁検査等も効果的に行うことが可能となる。特に、屋外で使用されることを想定される場合には本発明は有効である。 When the present invention is applied to the flying object 400 as shown in FIG. 7, it is possible to effectively perform surveying, bridge inspection, etc. in addition to general photographing applications (regardless of still images and moving images). . In particular, the present invention is effective when used outdoors.
　また、上述した制御部は、撮影部のパン方向の角度（順光における１８０度以内の任意の範囲）に応じて偏光を制御することとしているが、チルト角やロール角に応じて制御することとしてもよい。しかしながら、円偏光フィルタの特性を考慮すれば、撮影部のパン方向の角度に応じて偏光を制御することがより好ましい。 In addition, the control unit described above controls the polarization according to the angle in the pan direction of the photographing unit (an arbitrary range within 180 degrees in the forward light), but it controls according to the tilt angle and the roll angle. It is good. However, in consideration of the characteristics of the circularly polarizing filter, it is more preferable to control the polarization according to the angle of the photographing unit in the pan direction.
　上述した実施の形態は、本発明の理解を容易にするための例示に過ぎず、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良することができると共に、本発明にはその均等物が含まれることは言うまでもない。 The embodiment described above is merely an example for facilitating the understanding of the present invention, and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
