Description

この発明は、カメラのレンズに装着して当該レンズの光軸を中心とする３６０度の視野範囲を１枚のフィルムないし受像素子に円環状の画像として結像させるのに用いる全方位撮影用アタッチメントに関するものである。   The present invention is for omnidirectional photography that is attached to a lens of a camera and used to form a 360-degree field of view centered on the optical axis of the lens on a single film or image receiving element as an annular image. It is about attachment.

ある地点における全方位の景観を撮影したパノラマ画像を得るため、あるいは１台のカメラで広い範囲を監視するために、全方位撮影装置が利用されている。全方位撮影装置としては、魚眼レンズを用いたカメラが古くから利用されているが、部分球面ないし回転放物面を備えた凸面鏡（以下、「全方位ミラー」という。）をカメラのレンズから所定距離を隔てて対向配置することにより、全方位画像を得る技術が提案されている。   An omnidirectional photographing apparatus is used to obtain a panoramic image obtained by photographing an omnidirectional landscape at a certain point, or to monitor a wide range with one camera. As an omnidirectional photographing apparatus, a camera using a fisheye lens has been used for a long time. However, a convex mirror (hereinafter referred to as an “omnidirectional mirror”) having a partial spherical surface or a rotating paraboloid has a predetermined distance from the camera lens. A technique has been proposed in which an omnidirectional image is obtained by disposing them facing each other.

図６は、そのような従来装置の概要を示したもので、カメラ５のレンズ６の先端に装着される筒状のマウント２と、透明板４で支持されてレンズ６の光軸上に延びる支持ロッド３と、先端中心をこのロッド３の先端に固着してレンズ６に対向させた全方位ミラー１とによって構成されている。全方位ミラー１の周囲の被写体から出た光は、全方位ミラー１によってレンズ６に向けて反射され、当該反射光はロッド３を支持している透明板４及び光路となっているマウントの中空部２ａを通ってレンズ６に導かれ、カメラ５内のフィルムないし受像素子面上にリング状の画像となって結像する。   FIG. 6 shows an outline of such a conventional apparatus. A cylindrical mount 2 attached to the tip of the lens 6 of the camera 5 and a transparent plate 4 are supported to extend on the optical axis of the lens 6. The support rod 3 and the omnidirectional mirror 1 having the tip center fixed to the tip of the rod 3 and facing the lens 6 are configured. The light emitted from the subject around the omnidirectional mirror 1 is reflected by the omnidirectional mirror 1 toward the lens 6, and the reflected light is a transparent plate 4 that supports the rod 3 and the hollow of the mount serving as the optical path. The light is guided to the lens 6 through the part 2a, and forms a ring-shaped image on the film or the image receiving element surface in the camera 5.

この構造の全方位撮影装置は、レンズ６として一般的なズームレンズを用いることができ、従って図６でマウント２、透明板４、ロッド３及び全方位ミラー１で形成される部分を一般的なズームレンズに取り付けるアタッチメントとして提供することにより、全方位撮影装置が得られる。   In this omnidirectional imaging apparatus, a general zoom lens can be used as the lens 6, and therefore the portion formed by the mount 2, the transparent plate 4, the rod 3, and the omnidirectional mirror 1 in FIG. By providing as an attachment attached to the zoom lens, an omnidirectional photographing apparatus can be obtained.

従来のこの種の全方位撮影用アタッチメント（以下、単に「アタッチメント」という。）は、全方位ミラー１がマウント２に固定した固定長のロッド３の先端に固定されていた。このようなアタッチメントをズームレンズに装着して全方位撮影を行うときは、全方位ミラーの略焦点位置に形成される虚像にレンズの焦点を合わせ、ズーム比を変えることにより受像面上の画像の大きさを調整して、撮影する。
特開２００３−０２９３５６号公報 This type of conventional omnidirectional imaging attachment (hereinafter simply referred to as “attachment”) is fixed to the tip of a fixed-length rod 3 with an omnidirectional mirror 1 fixed to a mount 2. When such an attachment is attached to a zoom lens and omnidirectional imaging is performed, the lens is focused on a virtual image formed at a substantially focal position of the omnidirectional mirror, and the zoom ratio is changed to change the image on the image receiving surface. Adjust the size and shoot.
JP 2003-029356 A

カメラの前に設置した全方位ミラーを用いた全方位撮影は、カメラから見れば、全方位ミラーの焦点近くに結像している周囲３６０度の景観の虚像を撮影するということである。虚像の位置は全方位ミラーからの遠近によって変化するから、遠近のものをシャープに撮影するには、被写界深度の大きいレンズで、換言すればズームレンズを広角側にし、かつレンズと全方位ミラーとの間隔を大きくして撮影することが望ましい。しかしこれを実現しようとすると、アタッチメントの全方位ミラー１とマウント２との間隔Ｈを大きくしなければならない。更にこの間隔Ｈを大きくした状態で広角側を使用すると、結像面上の画像が小さくなるので、受像素子の画面一杯の像を得るためには、大きな径の全方位ミラーが必要になる。すなわち、鮮明な全方位画像を得るには、全方位ミラーの径Ｄが大きくかつ全方位ミラーとマウントとの間隔Ｈの大きな、従って大型のアタッチメントを用いなければならないということになる。   Omnidirectional shooting using an omnidirectional mirror installed in front of the camera means that, when viewed from the camera, a virtual image of a 360-degree surrounding landscape imaged near the focal point of the omnidirectional mirror is taken. Since the position of the virtual image changes depending on the perspective from the omnidirectional mirror, in order to photograph the perspective sharply, use a lens with a large depth of field, in other words, the zoom lens on the wide-angle side, and the lens and the omnidirectional It is desirable to take a picture with a large distance from the mirror. However, in order to realize this, the distance H between the omnidirectional mirror 1 and the mount 2 of the attachment must be increased. Further, if the wide-angle side is used with this distance H increased, the image on the imaging surface becomes smaller, and an omnidirectional mirror with a large diameter is required to obtain a full image of the image receiving element. . That is, in order to obtain a clear omnidirectional image, the diameter D of the omnidirectional mirror is large and the distance H between the omnidirectional mirror and the mount is large, and thus a large attachment must be used.

このことは、例えば複数地点での全方位の景観を撮影するために、カメラやアタッチメントを持ち運ぶときに、かさ張って持ち運びにくく、搬送中にぶつけたり落したりする危険も大きくなるという問題を生ずる。   This causes a problem that, for example, when taking a omnidirectional landscape at a plurality of points, when carrying a camera or an attachment, it is bulky and difficult to carry, and the risk of hitting or dropping during transportation increases.

また、アタッチメントをカメラに取り付けたときの画像の大きさやピントは、上記のようにレンズのズーム比及び焦点距離を調整することにより行われるが、使用するカメラとアタッチメントとが整合しない場合があり、図４に示すように画像をフィルムや受像素子の画面一杯にまで大きくするとピント調整範囲から外れて画像がぼけてしまい、画像を鮮明にしようとすると図５に示すように小さな画像２６しか取得できないという問題が発生することがあった。   Also, the size and focus of the image when the attachment is attached to the camera is performed by adjusting the zoom ratio and focal length of the lens as described above, but the camera to be used and the attachment may not match, As shown in FIG. 4, when the image is enlarged to the full screen of the film or the image receiving element, the image is out of focus adjustment range, and when the image is made clear, only a small image 26 is obtained as shown in FIG. There was a problem that it was impossible.

この発明は、上記の問題を解決するためになされたもので、第１の課題は、持ち運びが容易でかつ被写界深度の大きなアタッチメントを得ることであり、第２の課題は、どのようなカメラに取り付けてもフィルムや受像素子画面一杯の鮮明な画像が撮影できるアタッチメントを得ることである。   The present invention has been made to solve the above-mentioned problems. The first problem is to obtain an attachment that is easy to carry and has a large depth of field, and the second problem is what It is to obtain an attachment that can capture a clear image of a film or a full screen of the image receiving element even if it is attached to a camera.

本願の請求項１の発明は、カメラのレンズ先端に装着するマウント２の光路中心に延びるロッド３の先端に部分球面ないし回転放物面を備えた全方位ミラー１を取付けたアタッチメントにおいて、前記マウント２の上端に設けた支軸７回りに揺動して当該マウンドの空洞２ａ内へ収容される揺動枠８を設け、縮退部を備えた前記ロッド３を当該揺動枠８を介して装着し、不使用時に前記揺動枠８を揺動させると共に前記ロッド３を縮退させて前記全方位ミラー１を前記マウントの光路となっている空洞２ａに収納することを特徴とするアタッチメントを提供することにより、上記第１の課題を解決している。 The present invention of claim 1, in attachment mounted omnidirectional mirror 1 having a partially spherical or paraboloid in the tip of the rod 3 extending optical path center of the mount 2 to be mounted on the front of the lens of the camera, the mounting 2 is provided with a swing frame 8 swinging around a support shaft 7 provided at the upper end of 2 and accommodated in the cavity 2a of the mound, and the rod 3 provided with a retracting portion is mounted via the swing frame 8 and, an attachment, characterized in that for accommodating the omnidirectional mirror 1 by regress the rod 3 into the cavity 2a which is the optical path of the mounting with swinging the swing frame 8 when not in use By providing, the first problem is solved.

ロッド３の縮退構造としては、内筒を外筒内で進退させるテレスコピック構造や、ロッド先端を全方位ミラー１の内部へ挿入する下記実施形態の構造を採用できる。   As the contraction structure of the rod 3, a telescopic structure in which the inner cylinder is advanced and retracted in the outer cylinder and a structure of the following embodiment in which the rod tip is inserted into the omnidirectional mirror 1 can be adopted.

マウント２と全方位ミラー１との間隔Ｈは大きい方が望ましいので、一般的には１箇所の縮退構造のみで全方位ミラー１を円筒状のマウント２内に収容可能にすることは困難である。そこで実用的には、ロッド３の縮退部を複数箇所設けてロッド３を多段縮退構造とするか、又は下記実施形態に示すように、ロッド３に屈折部９を設けて、その屈折により、折畳む構造とする。   Since it is desirable that the distance H between the mount 2 and the omnidirectional mirror 1 is large, it is generally difficult to allow the omnidirectional mirror 1 to be accommodated in the cylindrical mount 2 with only one degenerate structure. . Therefore, practically, a plurality of degenerated portions of the rod 3 are provided so that the rod 3 has a multistage degenerated structure, or, as shown in the following embodiment, the rod 3 is provided with a refracting portion 9 and is bent by the refraction. Folding structure.

不使用時にロッド３を縮退させるための縮退部を設けたときは、その縮退途中の自由な位置で縮退部をロック可能にすることで、使用するカメラに合わせて全方位ミラー１とマウント２の間隔Ｈを調整可能な伸縮構造とすることができ、これを利用すれば、上記第１の課題と共に第２の課題を解決することができる。   When the retracting part for retracting the rod 3 when not in use is provided, the retracting part can be locked at a free position during the contracting, so that the omnidirectional mirror 1 and the mount 2 can be adjusted according to the camera to be used. It can be set as the elastic structure which can adjust the space | interval H, and if this is utilized, a 2nd subject can be solved with the said 1st subject.

本願の請求項２の発明は、上記請求項１の構造を備えたアタッチメントにおいて、前記ロッド３が伸縮可能かつ伸縮位置をロック可能であることを特徴とするものである。   The invention of claim 2 of the present application is characterized in that, in the attachment having the structure of claim 1, the rod 3 can be expanded and contracted and the expansion / contraction position can be locked.

伸縮部のロック構造としては、軸方向に螺進退する円錐内周面でコレット爪を開閉する構造や、ロッドの外周面を締め付けて固定しているコイルスプリングを巻き数を減じる方向に捩じって、内径を広げた状態で伸縮可能にする構造などを採用することができる。   The locking structure for the telescopic part includes a structure in which the collet claw is opened and closed on the inner peripheral surface of the cone that is screwed back and forth in the axial direction, and a coil spring that is tightened and fixed to the outer peripheral surface of the rod is twisted in a direction that reduces the number of turns. Thus, a structure that can be expanded and contracted with the inner diameter expanded can be employed.

以上説明したこの発明により、被写界深度が大きく、従って遠近差のある被写体をシャープに撮影することが可能で、かつ運搬時や保管時に全方位ミラー１をマウント２の円筒の内部に収容して、コンパクトに持ち運びないし保管することが可能なアタッチメントを得ることができる。   According to the present invention described above, it is possible to sharply photograph a subject with a large depth of field, and therefore a perspective difference, and the omnidirectional mirror 1 is accommodated in the cylinder of the mount 2 during transportation and storage. Thus, an attachment that can be carried or stored compactly can be obtained.

また、請求項２の発明によれば、上記効果が得られると共に、カメラとアタッチメントとが整合しない問題を生じないので、全方位景観の観察システムや室内外の監視システムなどの各システムの目的に最適な仕様のカメラを使用することが可能になり、また既存のカメラやレンズを流用することも可能になって、適切なシステムを経済的に構築できるという効果がある。   Further, according to the invention of claim 2, since the above-mentioned effect can be obtained and the problem that the camera and the attachment do not match does not occur, the purpose of each system such as an omnidirectional landscape observation system and an indoor / outdoor monitoring system can be obtained. It is possible to use a camera with an optimal specification, and it is also possible to divert existing cameras and lenses, so that an appropriate system can be constructed economically.

The inside of the mount 2 is a cavity, and a swing frame 8 is mounted on the upper end of the mount 2 so as to swing around the support shaft 7 and accommodated in the cavity. It is fixedly attached.

ロッド３は屈折部９で連結された上ロッド３ａと下ロッド３ｂからなり、下ロッド３ｂの基端が透明板４の中央に固定して、面直角方向に立設されている。上ロッド３ａの上端は、縮退部１０を介して全方位ミラー１内に挿入されている。   The rod 3 includes an upper rod 3a and a lower rod 3b connected by a refracting portion 9, and a base end of the lower rod 3b is fixed to the center of the transparent plate 4 and is erected in a direction perpendicular to the plane. The upper end of the upper rod 3 a is inserted into the omnidirectional mirror 1 through the degenerate portion 10.

全方位ミラー１は、回転放物凸面の反射面を備えており、使用時に一直線上としたロッド３の軸心は、当該反射面の軸心及びレンズ６の光軸と一致している。全方位ミラー１の内部は空洞で、その上端に支持円板１ａが固定されており、この支持円板の中央に全方位ミラー１の内部側に延びてその下端に突出するパイプ１１が立設されている。   The omnidirectional mirror 1 includes a reflecting surface having a paraboloidal convex surface, and the axis of the rod 3 that is in a straight line when in use coincides with the axis of the reflecting surface and the optical axis of the lens 6. The interior of the omnidirectional mirror 1 is hollow, and a support disk 1a is fixed to the upper end thereof. A pipe 11 is provided at the center of the support disk so as to extend to the inner side of the omnidirectional mirror 1 and project at the lower end thereof. Has been.

図３に示すように、上ロッド３ａの先端は、パイプ１１内に摺動自在に挿入されている。パイプ１１の先端には、雄ねじ１２が切ってあり、更にその先端に外周を若干小径として軸方向に切り込み１３を入れることで３本のロック爪１４が形成されている。雄ねじ１２には、ロッド側内面を円錐面１５としたロック筒１６が螺合されている。   As shown in FIG. 3, the tip of the upper rod 3 a is slidably inserted into the pipe 11. A male screw 12 is cut at the tip of the pipe 11, and three lock claws 14 are formed by making a cut 13 in the axial direction with a slightly smaller outer periphery at the tip. A lock cylinder 16 having a conical surface 15 on the rod side inner surface is screwed onto the male screw 12.

ロック筒１６を雄ねじ１２にねじ込むと、円錐内面１５がロック爪１４を内側に向けて押動し、上ロッド３ａの外周面がロック爪１４で把持されて固定される。一方、ロック筒１６を緩めると、ロック爪１４が緩み、上ロッド３ａをパイプ１１に引出し又は挿入することにより、上ロッド３ａが伸縮される。適宜な伸縮位置でロック筒１６を雄ねじ１２にねじ込むことにより、上ロッド３ａの伸縮位置が固定される。なお、図２の折畳み時には、上ロッド３ａは、パイプ１１内に一杯に挿入された状態でロックされる。   When the lock cylinder 16 is screwed into the male screw 12, the conical inner surface 15 pushes the lock claw 14 inward, and the outer peripheral surface of the upper rod 3a is gripped by the lock claw 14 and fixed. On the other hand, when the lock cylinder 16 is loosened, the lock claw 14 is loosened, and the upper rod 3a is extended or retracted by drawing or inserting the upper rod 3a into the pipe 11. By screwing the lock cylinder 16 into the male screw 12 at an appropriate expansion / contraction position, the expansion / contraction position of the upper rod 3a is fixed. 2 is locked in a state where the upper rod 3a is fully inserted into the pipe 11.

図３に示す屈折部９は、上下のロッドの対向端に板状突起と溝とを加工して、当該突起を溝内に挿入して支点ピン１７で連結した蝶番構造のもので、その伸長位置を固定するための固定筒１８が設けられている。固定筒１８は、下ロッド３ｂの上端に設けた雄ねじ１９に螺合しており、上ロッド３ａ側に螺進させたとき、上ロッド３ａ側の内周に設けた円錐面２０と上ロッド３ａの下端に設けた円錐面２１とが嵌合して、上ロッド３ａと下ロッド３ｂとが一直線となった位置で両者を固定する。固定筒１８を緩めてゆくと、下ロッド３ｂの雄ねじ１９との螺合が外れ、固定筒１８を屈折部９の下方までスライドして、ロッド３が屈折部３で屈折可能になる。   The refraction part 9 shown in FIG. 3 has a hinge structure in which plate-like protrusions and grooves are processed at opposite ends of the upper and lower rods, the protrusions are inserted into the grooves and connected by fulcrum pins 17.
