Conventionally, a stereoscopic camera that acquires a stereoscopic image by arranging two television cameras in parallel and capturing parallax images for the right eye and the left eye has been developed. The two lens devices used in such a stereoscopic camera are driven simultaneously so that the photographing conditions that change depending on the state (position) of the control target such as focus, zoom (focal length), and aperture always coincide.

２台のレンズ装置の撮影条件が同一になるように制御する立体カメラ用のレンズ制御装置としては、特許文献１に示すものがある。特許文献１に記載された立体カメラ用のレンズシステムは、完全に同一の仕様である右目用のレンズと左目用各レンズを備え、立体撮像時に右目用のレンズ装置及び左目用のレンズ装置のそれぞれの画角を略同一にするように制御を行っている。
Patent Document 1 discloses a lens control device for a stereoscopic camera that controls the imaging conditions of two lens devices to be the same. The lens system for a stereoscopic camera described in Patent Document 1 includes a right-eye lens and a left-eye lens that have completely the same specifications, and each of the right-eye lens device and the left-eye lens device during stereoscopic imaging. The control is performed so that the angles of view are substantially the same.
ところで、従来では、種類の全く異なる２つのレンズ装置を用いて立体撮像を行うことについては知見がなかった。種類の異なる２つのレンズ装置を用いて立体撮像を行うには、撮影条件が同一になるように各レンズ装置を制御する必要がある。このような制御を行う際には、２つのレンズ装置のそれぞれの諸元が全く異なり、各レンズ装置の撮影条件を同一にすることができないため、良好な立体画像を得ることができない。しかし、ユーザは、種類の異なる２つのレンズ装置を用いて立体撮像を行うときに、これら２つのレンズ装置が立体撮像用として適した組み合わせであるかどうか判断することができない。
By the way, conventionally, there was no knowledge about performing stereoscopic imaging using two lens devices of completely different types. In order to perform stereoscopic imaging using two different types of lens devices, it is necessary to control each lens device so that the imaging conditions are the same. When performing such control, the specifications of the two lens devices are completely different, and the photographing conditions of the lens devices cannot be made the same, so that a good stereoscopic image cannot be obtained. However, when performing stereoscopic imaging using two different types of lens devices, the user cannot determine whether these two lens devices are a suitable combination for stereoscopic imaging.

レンズ装置１０Ａは、立体画像の撮影を行わない場合には、レンズ装置１０Ｂと無線通信を行わない状態に設定され、カメラ本体１００Ａに装着されることで、ビデオカメラのレンズ装置として単体で使用することができる。
The lens device 10A is set to a state in which wireless communication with the lens device 10B is not performed when a stereoscopic image is not taken, and is used alone as a lens device of a video camera by being attached to the camera body 100A. be able to.
ＣＰＵ３０は、レンズ装置１０Ａとレンズ装置１０Ｂとが通信ケーブル２と無線アダプタ２０により互いに接続されたとき、レンズ装置１０Ａとレンズ装置１０Ｂが、立体画像の撮影を行う組み合わせとして適しているかを判断する適性判断モードを実行する。
When the lens device 10A and the lens device 10B are connected to each other by the communication cable 2 and the wireless adapter 20, the CPU 30 determines whether the lens device 10A and the lens device 10B are suitable as a combination for taking a stereoscopic image. Execute the judgment mode.
適性判断モードは、レンズ装置１０Ａ及びレンズ装置１０Ｂのうちいずれか一方をメイン側として、メイン側のＣＰＵ３０で行う。レンズ装置１０Ａ及びレンズ装置１０Ｂのうちどちらをメイン側とするかは予め設定によって決められていてもよい。又は、ユーザによって、レンズ装置１０Ａ及びレンズ装置１０Ｂのうちいずれをメイン側とするか選択可能であってもよい。以下の説明では、レンズ装置１０Ａをメイン側とした場合を例に説明する。

Which of the lens device 10A and the lens device 10B is used as the main side may be determined in advance. Alternatively, the user may select which of the lens device 10A and the lens device 10B is the main side. In the following description, the case where the lens device 10A is the main side will be described as an example.
図３は、レンズ装置１０Ａとレンズ装置１０Ｂが無線アダプタ２０を用いて接続されたときの処理手順を示したフローチャートである。
FIG. 3 is a flowchart showing a processing procedure when the lens device 10A and the lens device 10B are connected using the wireless adapter 20.
レンズ装置１０Ａとレンズ装置１０Ｂとが無線アダプタ２０を用いて接続されると、先ず、メイン側のＣＰＵ３０は、レンズ装置１０Ａとレンズ装置１０Ｂとの組み合わせの適性の判断を過去に行ったことがあるかどうかを判断する（ステップＳ１０）。そして、レンズ装置１０Ａとレンズ装置１０Ｂとの組み合わせの適性の判断を過去に行ったことがない場合には、ステップＳ１２の処理手順へ進む。レンズ装置１０Ａとレンズ装置１０Ｂとの組み合わせの適性の判断を既に行ったことがある場合には、本フローの最初の状態に戻る。
When the lens device 10A and the lens device 10B are connected using the wireless adapter 20, first, the main CPU 30 has previously determined the suitability of the combination of the lens device 10A and the lens device 10B. Is determined (step S10). If the suitability of the combination of the lens device 10A and the lens device 10B has not been determined in the past, the process proceeds to step S12. If the suitability of the combination of the lens device 10A and the lens device 10B has already been determined, the process returns to the initial state of this flow.
ステップＳ１２において、レンズ装置１０ＡのＣＰＵ３０は、接続先であるレンズ装置１０Ｂからレンズ装置１０Ｂに固有の識別データを受信する制御を実行する。そして、ＣＰＵ３０は、受信した識別データに含まれる型名に基づき、記憶部４４に記憶された参照用データからレンズ装置１０Ｂの型名に関連付けられた諸元情報（ここでは焦点距離と被写体距離）を抽出する。その後、ステップＳ１４の処理手順に進む。
In step S12, the CPU 30 of the lens device 10A executes control for receiving identification data unique to the lens device 10B from the lens device 10B that is the connection destination. Then, based on the model name included in the received identification data, the CPU 30 stores specification information (here, focal length and subject distance) associated with the model name of the lens device 10B from the reference data stored in the storage unit 44. To extract. Thereafter, the process proceeds to step S14.
ステップＳ１４において、ＣＰＵ３０は、自己諸元データに基づくレンズ装置１０Ａの焦点距離及び被写体距離と、抽出したレンズ装置１０Ｂの焦点距離及び被写体距離とを比較し、焦点距離及び被写体距離それぞれついて重複範囲を演算する。その後、ステップＳ１６の処理手順に進む。
In step S14, the CPU 30 compares the focal length and subject distance of the lens device 10A based on the self-spec data with the focal length and subject distance of the extracted lens device 10B, and sets an overlapping range for each of the focal length and subject distance. Calculate. Thereafter, the process proceeds to step S16.
ここで、諸元情報の重複範囲について説明する。図４は、２つのレンズ装置の共通する諸元情報としての焦点距離が、互いに重複する範囲を説明する図である。図４に示す例では、レンズ装置１０Ａの焦点距離とレンズ装置１０Ｂの焦点距離とが一部の範囲で重複している状態を示している。
Here, the overlapping range of specification information is explained. FIG. 4 is a diagram illustrating a range in which focal lengths as specification information common to two lens apparatuses overlap each other. In the example illustrated in FIG. 4, the focal length of the lens device 10A and the focal length of the lens device 10B overlap in a partial range.
図４において、レンズ装置１０Ａの諸元情報である焦点距離を４０ｍｍ～１００ｍｍの範囲とし、レンズ装置１０Ｂの諸元情報である焦点距離を６０ｍｍ～１２０ｍｍの範囲とした場合、レンズ装置１０Ａとレンズ装置１０Ｂの焦点距離の重複範囲は６０ｍｍ～１００ｍｍとなる。
In FIG. 4, when the focal length that is the specification information of the lens device 10A is in the range of 40 mm to 100 mm and the focal length that is the specification information of the lens device 10B is in the range of 60 mm to 120 mm, the lens device 10A and the lens device The overlapping range of the focal length of 10B is 60 mm to 100 mm.
レンズ装置１０Ａの諸元情報である焦点距離を５０ｍｍ～１００ｍｍの範囲とし、レンズ装置１０Ｂの諸元情報である焦点距離を５０ｍｍ～１００ｍｍの範囲とした場合、レンズ装置１０Ａとレンズ装置１０Ｂの焦点距離は完全に一致しており、重複範囲は５０ｍｍ～１００ｍｍとなる。
When the focal length, which is the specification information of the lens device 10A, is in the range of 50 mm to 100 mm, and the focal length, which is the specification information of the lens device 10B, is in the range of 50 mm to 100 mm, the focal length of the lens device 10A and the lens device 10B. Are completely coincident, and the overlapping range is 50 mm to 100 mm.
レンズ装置１０Ａの諸元情報である焦点距離を５０ｍｍ～７０ｍｍの範囲とし、レンズ装置１０Ｂの諸元情報である焦点距離を８０ｍｍ～１００ｍｍの範囲とした場合、レンズ装置１０Ａとレンズ装置１０Ｂの焦点距離は全く重複しないため、重複範囲は存在しない。
When the focal length that is the specification information of the lens device 10A is in the range of 50 mm to 70 mm and the focal length that is the specification information of the lens device 10B is in the range of 80 mm to 100 mm, the focal length of the lens device 10A and the lens device 10B. Does not overlap at all, so there is no overlapping range.
被写体距離の重複範囲についても、上述した焦点距離の重複範囲と同様に決定される。
The subject distance overlap range is also determined in the same manner as the focal length overlap range described above.
図３のフローチャートの処理手順の説明に戻り、ステップＳ１６において、ＣＰＵ３０は、焦点距離の重複範囲、及び被写体距離の重複範囲が存在するか否かを判断する。焦点距離及び被写体距離のうち少なくとも一方について重複範囲が存在する場合には、ステップＳ１８の処理手順へ進む。焦点距離及び被写体距離のいずれも重複範囲が存在しない場合には、ステップＳ２０の処理手順へ進む。
3, returning to the description of the processing procedure of the flowchart in FIG. 3, in step S <b> 16, the CPU 30 determines whether or not there is an overlapping range of focal lengths and an overlapping range of subject distances. If there is an overlapping range for at least one of the focal length and the subject distance, the process proceeds to step S18. If neither the focal distance nor the subject distance has an overlapping range, the process proceeds to step S20.
ステップＳ１８において、ＣＰＵ３０は、レンズ装置１０Ａとレンズ装置１０Ｂの焦点距離の重複範囲を、無線アダプタ２０の表示部２４に表示させる。その後、ステップＳ１０の処理手順へ戻る。ユーザは、表示部２４への表示によって、レンズ装置１０Ａ及びレンズ装置１０Ｂの組み合わせがどの程度適性であるかを確認することができる。
In step S18, the CPU 30 causes the display unit 24 of the wireless adapter 20 to display the overlapping range of the focal lengths of the lens device 10A and the lens device 10B. Thereafter, the process returns to step S10. The user can confirm how appropriate the combination of the lens device 10A and the lens device 10B is by displaying on the display unit 24.
次に、表示部２４における表示について説明する。
Next, the display on the display unit 24 will be described.
図５は、諸元情報の重複範囲を表示部２４に表示させたときの表示画面の一例を示す図である。図５の例は、表示部２４がＬＣＤで構成され、そのＬＣＤの画面３００を示している。ＣＰＵ３０は、画面３００に、レンズ装置１０Ａの焦点距離と、レンズ装置１０Ｂの焦点距離とを同時に表示させる。こうすれば、ユーザは、組み合わせた２つのレンズ装置１０Ａとレンズ装置１０Ｂそれぞれの焦点距離とともに、これら焦点距離の重複範囲を視覚的に判断することができる。図５の例では、画面３００にレンズ装置１０Ａ及びレンズ装置１０Ｂの焦点距離と重複範囲をグラフで示されているが、数値やその他の図形や記号を用いて表示されてもよい。また、被写体距離の重複範囲を表示させる場合でも、表示部２４に同様に表示される。上述した例では、焦点距離と被写体距離についてそれぞれの重複範囲を表示しているが、表示させる諸元情報はこれらに限定されない。図５に示すように、諸元情報としてＦナンバーの重複範囲を表示させてもよい。
FIG. 5 is a diagram showing an example of a display screen when the overlapping range of the specification information is displayed on the display unit 24. In the example of FIG. 5, the display unit 24 is configured by an LCD and a screen 300 of the LCD is shown. The CPU 30 causes the screen 300 to simultaneously display the focal length of the lens device 10A and the focal length of the lens device 10B. In this way, the user can visually determine the overlapping range of the focal lengths together with the focal lengths of the two combined lens devices 10A and 10B. In the example of FIG. 5, the focal lengths and overlapping ranges of the lens device 10 </ b> A and the lens device 10 </ b> B are shown as graphs on the screen 300, but may be displayed using numerical values, other figures and symbols. Even when the overlapping range of the subject distance is displayed, it is displayed on the display unit 24 in the same manner. In the example described above, the overlapping ranges for the focal length and the subject distance are displayed, but the specification information to be displayed is not limited to these. As shown in FIG. 5, the overlapping range of the F number may be displayed as the specification information.
また、図５に示すように、表示部２４におけるレンズ装置１０Ａ及びレンズ装置１０Ｂの諸元情報の重複範囲を示す表示は、ユーザの操作によって選択的に切り換えることが可能であってもよい。図５に示す例では、焦点距離が選択され、その表副範囲が表示されているが、ユーザの操作によって表示切替ボタン３０２を「被写体距離」や「Ｆｎｏ（ここでは、Ｆナンバーを意味する。）」に切り換えにより、画面３００に、被写体距離の重複範囲や、Ｆナンバーの重複範囲が切り換えて表示されてもよい。表示部２４の表示を切り替える表示切替ボタン３０２は、無線アダプタ２０に設けられていてもよい。
Further, as shown in FIG. 5, the display indicating the overlapping range of the specification information of the lens device 10A and the lens device 10B on the display unit 24 may be selectively switched by a user operation. In the example shown in FIG. 5, the focal length is selected and the front and sub ranges are displayed. However, the display switching button 302 is moved by the user's operation to “subject distance” or “Fno (here, F number is meant). ) "May be displayed on the screen 300 by switching the overlapping range of the subject distance and the overlapping range of the F number. The display switching button 302 for switching the display on the display unit 24 may be provided in the wireless adapter 20.
図３のフローチャートの説明に戻り、ステップＳ２０では、ＣＰＵ３０は、レンズ装置１０Ａとレンズ装置１０Ｂの焦点距離の重複範囲が存在しないことを、無線アダプタ２０の表示部２４に表示させる。ここで、表示部２４は、レンズ装置１０Ａとレンズ装置１０Ｂの焦点距離の重複範囲が存在しない状態を示すグラフや、重複範囲が存在しない旨のメッセージを表示するように制御される。ユーザは、表示部２４の表示によって、レンズ装置１０Ａ及びレンズ装置１０Ｂの組み合わせが不適性であることを確認することができる。その後、ステップＳ１０の処理手順へ戻る。
Returning to the description of the flowchart of FIG. 3, in step S20, the CPU 30 causes the display unit 24 of the wireless adapter 20 to display that there is no overlapping range of the focal lengths of the lens device 10A and the lens device 10B. Here, the display unit 24 is controlled to display a graph indicating a state where there is no overlapping range of focal lengths of the lens device 10A and the lens device 10B, and a message indicating that there is no overlapping range. The user can confirm from the display on the display unit 24 that the combination of the lens device 10A and the lens device 10B is inappropriate. Thereafter, the process returns to step S10.
上述したレンズシステム１０によれば、ユーザは、立体画像の撮影に、種類の異なる２つのレンズ装置を用いる際に、無線アダプタ２０を用いることで２つのレンズ装置同士を通信ケーブルなどで直接接続する必要がなく、これら２つのレンズ装置の組み合わせが立体画像の撮影を行う上で適しているかどうかを容易に判断することができる。
According to the lens system 10 described above, when using two different types of lens devices for capturing a stereoscopic image, the user directly connects the two lens devices with a communication cable or the like by using the wireless adapter 20. It is not necessary, and it can be easily determined whether the combination of these two lens devices is suitable for taking a stereoscopic image.
また、ユーザは、同じ種類の２つのレンズ装置を所有している必要がない。例えば、ユーザは、予め１つのレンズ装置を所有している場合に、所有しているレンズ装置と組み合わせて立体画像の撮影で用いるための候補のレンズ装置を、レンズシステムにおける上述した適性判断モードによって、他の複数のレンズ装置の群から選択することができる。
Also, the user does not have to own two lens devices of the same type. For example, when the user has one lens device in advance, a candidate lens device to be used for photographing a stereoscopic image in combination with the lens device owned by the user is determined by the above-described aptitude determination mode in the lens system. And can be selected from a group of other lens devices.
更に、ユーザは、２つのレンズ装置の組み合わせの適性を判断する際に、無線アダプタの表示部２４の表示によって適性を確認することができるため、各レンズ装置をカメラ本体に取り付けたり、実際に立体画像の撮影を行った上で立体画像を再生して確認したりする必要がない。
Furthermore, when the user determines the suitability of the combination of the two lens devices, the suitability can be confirmed by the display on the display unit 24 of the wireless adapter, so that each lens device can be attached to the camera body or actually three-dimensional. There is no need to replay and check a stereoscopic image after shooting the image.
次に、本発明に係るレンズシステムの変形例について説明する。
Next, a modification of the lens system according to the present invention will be described.
図４に示す処理手順では、先に焦点距離及び被写体距離の重複範囲の演算を行ったが、焦点距離及び被写体距離のうち少なくとも一方の重複範囲のみ演算し、表示部２４に表示してもよい。レンズ装置１０Ａは、ユーザの設定によって、どの諸元情報の重複範囲を表示させるか予め設定されていてもよい。
In the processing procedure shown in FIG. 4, the overlapping range of the focal distance and the subject distance is calculated first, but only the overlapping range of at least one of the focal distance and the subject distance may be calculated and displayed on the display unit 24. . The lens device 10 </ b> A may be preset in accordance with user settings to display which specification information overlap range.
表示部２４がＬＥＤである場合には、諸元情報の重複範囲がない場合には、ＬＥＤの点滅のみでユーザに表示を行ってもよい。例えば、レンズ装置１０Ａとレンズ装置１０Ｂにおいて焦点距離の重複範囲が存在するか否かをＬＥＤの点滅動作を変化させることによって表示してもよい。また、レンズ装置１０Ａとレンズ装置１０Ｂにおいて焦点距離の重複範囲の広さに応じてＬＥＤを点滅させる間隔（ＬＥＤの発光から消光までの時間）を変化させてもよい。例えば、重複範囲が、閾値より大きい場合にＬＥＤを長い間隔で点滅させ、閾値未満の場合にはＬＥＤを短い間隔で点滅させてもよい。ここで、閾値とは、例えば、レンズ装置１０Ａの焦点距離とレンズ装置１０Ｂの焦点距離との少なくとも一方を含む全範囲の長さに対する重複範囲の割合を用いることができる。例えば、閾値は、２つのレンズ装置１０Ａ及び１０Ｂの両方の焦点距離を含む全範囲の１０％とする。例えば、レンズ装置１０Ａの諸元情報である焦点距離を４０ｍｍ～１００ｍｍの範囲とし、レンズ装置１０Ｂの諸元情報である焦点距離を６０ｍｍ～１２０ｍｍの範囲とした場合、レンズ装置１０Ａとレンズ装置１０Ｂの焦点距離の全範囲は４０ｍｍ～１２０ｍｍであり、全範囲の長さは８０ｍｍであり、閾値は８ｍｍ（＝８０ｍｍ×１０％）となる。なお、閾値は、上述のものに限定されず、他の所定値を用いてもよい。
When the display unit 24 is an LED, if there is no overlapping range of specification information, the display may be made to the user only by blinking the LED. For example, whether or not there is an overlapping range of focal lengths in the lens device 10A and the lens device 10B may be displayed by changing the blinking operation of the LED. Further, in the lens device 10A and the lens device 10B, the interval at which the LED blinks (the time from light emission to extinction of the LED) may be changed in accordance with the width of the overlapping range of the focal length. For example, the LED may be blinked at a long interval when the overlapping range is larger than the threshold, and the LED may be blinked at a short interval when the overlapping range is less than the threshold. Here, for example, the ratio of the overlapping range to the length of the entire range including at least one of the focal length of the lens device 10A and the focal length of the lens device 10B can be used as the threshold value. For example, the threshold value is 10% of the entire range including the focal lengths of the two lens apparatuses 10A and 10B. For example, when the focal length that is the specification information of the lens device 10A is in the range of 40 mm to 100 mm and the focal length that is the specification information of the lens device 10B is in the range of 60 mm to 120 mm, the lens device 10A and the lens device 10B The entire range of the focal length is 40 mm to 120 mm, the length of the entire range is 80 mm, and the threshold value is 8 mm (= 80 mm × 10%). The threshold value is not limited to the above-mentioned threshold value, and another predetermined value may be used.
表示部２４は、上述したＬＣＤとＬＥＤをともに備えた構成としてもよく、いずれか一方のみを備えた構成としてもよい。
The display unit 24 may be configured to include both the LCD and the LED described above, or may be configured to include only one of them.
図４に示す処理手順において、ＣＰＵ３０は、レンズ装置１０Ａの諸元情報として、焦点距離、被写体距離、Ｆ値だけでなく、Ｆドロップを使用し、これらの重複範囲を演算し、ユーザに通知してもよい。
In the processing procedure shown in FIG. 4, the CPU 30 uses not only the focal length, the subject distance, and the F value as the specification information of the lens device 10A, but also F drop, calculates the overlapping range, and notifies the user. May be.
上述のレンズシステムの構成において、ＣＰＵ３０が焦点距離及び被写体距離それぞれについて重複範囲を演算する演算部を兼ねているが、ＣＰＵ３０とは別に演算部を設けてもよい。
In the configuration of the lens system described above, the CPU 30 also functions as a calculation unit that calculates the overlapping range for each of the focal length and the subject distance. However, a calculation unit may be provided separately from the CPU 30.
又は、ＣＰＵ３０は、レンズ装置１０Ａとレンズ装置１０Ｂを通信接続させて、組み合わせの適性を判断したことがあるかを示す履歴情報を記憶部４４に記憶させておいてもよい。こうすれば、レンズ装置１０Ａは、記憶部４４から履歴情報を読み出すことで、レンズ装置１０Ａとレンズ装置１０Ｂとの組み合わせの適性の判断を過去に行ったことがあるかどうか判断することができる。こうすれば、レンズ装置１０Ａとレンズ装置１０Ｂを２回目以降に接続する場合には、ＣＰＵ３０は、諸元情報の重複範囲を演算することなく、履歴情報に基づいて、諸元情報の重複範囲を表示させることができる。例えば、図４に示す処理手順のステップＳ１０において、ＣＰＵ３０は、レンズ装置１０Ｂからレンズ装置１０Ｂに固有の識別データを参照しなくても、記憶部４４に記憶されている履歴情報に基づいて、レンズ装置１０Ａとレンズ装置１０Ｂとの組み合わせの適性の判断を過去に行ったことがあるかどうか判断することができる。
Alternatively, the CPU 30 may cause the storage unit 44 to store history information indicating whether the lens device 10A and the lens device 10B are connected by communication and have determined the suitability of the combination. In this way, the lens device 10A can determine whether or not the suitability of the combination of the lens device 10A and the lens device 10B has been determined in the past by reading the history information from the storage unit 44. In this way, when the lens device 10A and the lens device 10B are connected for the second time or later, the CPU 30 calculates the overlapping range of the specification information based on the history information without calculating the overlapping range of the specification information. Can be displayed. For example, in step S10 of the processing procedure shown in FIG. 4, the CPU 30 does not refer to identification data unique to the lens device 10B from the lens device 10B, but based on the history information stored in the storage unit 44, It can be determined whether the suitability of the combination of the device 10A and the lens device 10B has been determined in the past.
履歴情報には、レンズ装置１０Ａに接続されたレンズ装置とこのレンズ装置がどの程度の適性であったかの情報とを含んでいてもよい。こうすれば、ＣＰＵ３０は、履歴情報を参照することで、例えばレンズ装置１０Ａと適性の高い物から順位を付け、順位とその順位に該当するレンズ装置の情報を表示部２４に表示させることができる。
The history information may include a lens device connected to the lens device 10A and information on how suitable the lens device is. In this way, by referring to the history information, the CPU 30 can rank, for example, the lens apparatus 10A and a highly suitable object, and display the rank and the information of the lens apparatus corresponding to the rank on the display unit 24. .
