- a part of the adapter 20 itself is also imaged outside the subject in the annular image 30. Therefore, it is necessary to exclude these portions from the target area for image evaluation for focus control so that these portions are not focused.
- annular image 30 in FIG. 15 a portion corresponding to the middle vicinity 139 of the captured image 138 at the time of normal imaging in FIG. 14 is an annular portion 32 in the vicinity of the center of the annular image 30. Therefore, when the omnidirectional imaging is performed using the adapter 20 provided with the single reflection type omnidirectional imaging optical system 25, the evaluation target area of the autofocus control in the captured image is changed to a range different from that in the normal imaging. There is a need.
- the control unit 150 of the imaging apparatus 10 restricts the evaluation target area of the autofocus control to the annular portion 32 near the center of the annular image 30 and captures in the annular portion 32 during all-round imaging.
- Autofocus control is performed so that the subject is in focus.
- the control unit 150 calculates a focal position (focus position) so as to focus on the subject shown in the annular portion 32 in the annular image 30 and instructs the optical component driving unit 114.
- the optical component driving unit 114 drives the focus motor 114b based on an instruction from the control unit 150 to move the focus lens, thereby focusing the omnidirectional imaging optical system and the imaging optical system 111 on the annular portion 32. Automatically focus on the subject.
- the double reflection type omnidirectional imaging optical system 21 has optical characteristics such that the focal points of all subjects at an arbitrary distance from the omnidirectional imaging optical system 21 are gathered in or near the omnidirectional imaging optical system 21.
- the focal points 218 of all the subjects are positioned between the two reflecting surfaces 212 and 213 in the omnidirectional imaging optical system 21. It is optically designed.
- the two-reflection type omnidirectional imaging optical system 21 is attached to the imaging unit 110, the distance between the omnidirectional imaging optical system 21 and the imaging optical system 111 of the imaging apparatus 10 is very close. Therefore, when the adapter 20 is mounted, it is necessary to adjust the focal position of the imaging optical system 111 to the very vicinity (macro position) of the imaging optical system 111.
- the control unit 150 sets the focal position (focus position) of the imaging optical system 111 to a specific position on the short distance side or the vicinity thereof (for example, all-around imaging optical).
- the position of the focal point 218 inside the system 21 or the vicinity thereof is controlled.
- the focus position adjustment range during normal imaging is wide (from the macro position to infinity)
- the focus position adjustment range during all-around imaging is the specific position or its vicinity (for example, within the all-around imaging optical system 21).
- the position of the focal point 218 or the vicinity thereof is, for example, a limited range in which the distance from the imaging optical system 111 is only about several centimeters).
- the control unit 150 fixes the focal position of the imaging optical system 111 to the closest position (macro position) within the range that can be adjusted by the focus control mechanism of the imaging apparatus 10. Also good. Alternatively, the control unit 150 may adjust the focal position of the imaging optical system 111 within the specific position or in the vicinity thereof.
- the focus position of the imaging optical system 111 can be adjusted to the focus 218 of all the subjects in the all-around imaging optical system 21 described above. Therefore, it is possible to optimize the focus position according to the optical characteristics of the omnidirectional imaging optical system 21 and automatically obtain the annular image 30 focused on the subject to be imaged all around.
- the adjustment range of the focal position of the imaging optical system 111 by the autofocus function (the focal length focused on the subject by the AF function is set).
- the range to be searched) ranges widely from the macro position to infinity.
- the appropriate focal position is limited to the inside or the vicinity of the omnidirectional imaging optical system 21 as described above, so that it is not necessary to adjust the focus position to a long distance. Therefore, if wide-range autofocus control is performed at the time of all-around imaging using the adapter 20 as in normal imaging, the possibility of erroneous control increases.
- the control unit 150 limits the adjustment range of the focal position by the AF function to only a predetermined range near the imaging optical system 111.
- the predetermined range in the vicinity of the imaging optical system 111 is, for example, the position of the focal point 218 in the all-around imaging optical system 21 or a range in the vicinity thereof, or a range around the macro position.
- the omnidirectional imaging optical system has an optical characteristic such that the focus of all subjects at an arbitrary distance from the omnidirectional imaging optical system is located in or near the omnidirectional imaging optical system.
- it may be a type that reflects the subject light three or more times.
- annular image 30 that captures the entire surrounding subject is obtained.
- the annular image 30 exists only in the central portion of the rectangular captured image output from the image sensor 112.
- the evaluation target area for automatic exposure control is changed from the evaluation target range for normal imaging (for example, the entire area of the rectangular captured image), and the area other than the annular image 30 in the captured image is changed. It is preferable that the exposure control is outside the evaluation target range.
- the control unit 150 of the imaging device 10 limits the evaluation target area for automatic exposure control in the captured image to the area in the annular image 30, and An area other than the annular image 30 (solid area in FIG. 5) is excluded from the evaluation target area.
- the evaluation target area of the automatic exposure control is only the area of the annular image 30 in which the entire surrounding subject is reflected, and the control unit 150 uses the luminance value of the pixel in the annular image 30 to Automatic control of exposure.
- the brightness of the annular image 30 can be appropriately controlled without being affected by the area other than the annular image 30.
- the imaging assistance function is a function for assisting the imaging operation by the imaging unit 110.
- This imaging assistance function includes, for example, a corrected camera shake correction function that corrects disturbance of a captured image caused by a user's camera shake during imaging, a face detection function that detects a human face in the captured image, and the like.
- a normal imaging apparatus 10 having a camera shake correction function camera shake detection and correction processing is controlled in accordance with normal imaging using only the normal imaging optical system 111, and the entire imaging using the omnidirectional imaging optical system 21 is controlled. Control suitable for surrounding imaging is not performed. Therefore, if the camera shake correction function controlled in accordance with the normal imaging is maintained as it is at the time of all-around imaging with the adapter 20 attached, an appropriate annular image 30 may not be obtained.
- the control unit 150 of the imaging device 10 invalidates the camera shake correction function. Thereby, since an inappropriate camera shake correction process is not performed on the annular image 30 at the time of all-round imaging, an appropriate annular image 30 can be obtained.
- the control unit 150 of the imaging device 10 invalidates the face detection function.

Thereby, at the time of all-around imaging, the malfunction by the inappropriate imaging auxiliary function can be prevented, and the annular image 30 with appropriate image quality can be obtained.
- the imaging apparatus 10 sets imaging operation settings (imaging parameters such as angle of view, focus, and exposure) and display operation settings when the adapter 20 is attached. Optimized according to the optical characteristics of the optical system 21. However, even though various settings are optimized as described above, there may be a case where the optimum settings cannot be maintained due to a user's erroneous operation.
- the control unit 150 of the imaging device 10 automatically optimizes the setting of the omnidirectional imaging operation and the setting of the display operation, and then performs the optimization. Disable user operations that change settings. For example, even if the user operates the operation unit 160 of the imaging apparatus 10, the control unit 150 cannot change the setting of the imaging parameters such as the optimized angle of view, focus, and exposure, and on / off of the display inversion function.

まず、図1~図5を参照して、本発明の第1の実施形態に係る撮像装置10の外観構成について詳細に説明する。図1~図5は、本実施形態に係る撮像装置10の外観構成を示す斜視図、正面図である。本発明の撮像装置は、例えば、図1に示す撮像装置10のようなデジタルカメラで具現されるが、かかる例に限定されず、撮像機能を備えた任意の電子機器に適用可能である。
次に、図6を参照して、本実施形態に係るアダプタ20が具備する全周囲撮像光学系21の構成例について説明する。図6は、本実施形態に係る二回反射タイプの全周囲撮像光学系21を示す断面図である。
次に、図7を参照して、本実施形態に係る撮像装置10の構成について詳細に説明する。図7は、本実施形態に係る撮像装置10のハードウェア構成を示す模式図である。
撮像光学系111を介して撮像素子112に被写体像が入射すると、撮像素子112は、撮像範囲内の被写体像を撮像する。即ち、撮像素子112は、撮像光学系111により撮像面に結像された光学像を光電変換して、撮像画像を表すアナログ画像信号を出力する。この撮像時には、制御部150は、撮像画像における所定のAF検波枠内の画像信号を処理することによって、撮像光学系111の焦点が該AF検波枠内の特定の被写体に合焦するような焦点位置(フォーカスポジション)を計算し、光学部品駆動部114に指示する。光学部品駆動部114は、制御部150の指示に基づき、フォーカスモータ114bを駆動して、フォーカスレンズを移動させることによって、撮像光学系111の焦点を上記特定の被写体に自動的に合焦させる。
上記撮像時には、制御部150は、撮像画像における所定のAE検波枠内の画像信号の信号レベルに基づいて、撮像中の撮像画像に適した露光量を計算し、光学部品駆動部114又はTG113に指示する。光学部品駆動部114は、制御部150の指示に基づき、撮像光学系111の絞りの開度を調整して、撮像素子112に入射される被写体像の露光量を調整する。また、TG113は、制御部150の指示に基づいて、タイミング信号を撮像素子112に供給し、このタイミング信号により撮像素子112におけるシャッタースピードが制御される。この結果、撮像画像の明るさが適切となるように、撮像画像の露出が自動的に制御される。
信号処理部122は、制御部150の制御に基づいて、撮像素子112から出力されたアナログ画像信号に対してアナログ信号処理(増幅等)を行い、その後、デジタル画像信号にA/D変換する。さらに、信号処理部122は、制御部150の制御に基づいて、デジタル画像信号に対して、ノイズ除去、ホワイトバランス調整、色補正、エッジ強調、ガンマ補正等のデジタル信号処理を施す。
信号処理部122が上記信号処理後の画像信号を表示部130に出力すると、表示部130は、制御部150の制御に基づいて、該画像信号が表す撮像中の撮像画像(スルー画像)を表示する。このスルー画像(動画)を表示することによって、ユーザは、撮像方向や画角、被写体の撮像状態などを視認して、所望のシャッターチャンスで所望の被写体の撮像画像を記録できるようになる。また、表示部130は、制御部150の制御に基づいて、記録媒体に記録されている画像データを再生することによって得られた画像も表示する。
記録再生部140は、制御部150の制御に基づいて、撮像画像の圧縮記録処理を行う。例えば、動画撮像モードにおいて、レコードボタン165が押下された場合、記録再生部140は、撮像画像(動画)を表す画像信号を例えばJPEG(Joint Photographic Experts Group)等の所定の圧縮符号化方式で圧縮する。さらに、記録再生部140は、該圧縮した画像信号を、動画データとして記録媒体に記録する。また、静止画撮像モードにおいて、レリーズボタン164が押下された場合、記録再生部140は、レリーズボタン164からのレリーズ信号に応じて、撮像画像(静止画)を表す画像信号を所定の圧縮符号化方式で圧縮して、静止画データとして記録媒体に記録する。
記録再生部140は、制御部150の制御に基づいて、メモリカード167などの記録媒体に記録された画像の再生処理を行う。再生モードにおいて、操作部160から再生指示が入力された場合、記録再生部140は、記録媒体に記録されている圧縮画像データを伸張し、得られた再生画像信号を表示部130に出力して表示させる。
撮像装置10は、各種のセンサで検出された外部環境や、操作部160に対するユーザ操作に基づいて、撮像装置10が有する各種の機能や、撮像装置10の動作の設定処理を行う。撮像装置10の機能としては、例えば、ズーム機能、AF機能、AE機能、フラッシュ機能、セルフタイマ機能、連写撮像機能、撮像画像の画質や画像サイズ、シャッタースピード、ホワイトバランス等の調整機能、撮像補助機能、表示機能などがある。
次に、さらに図7を参照しながら、本実施形態に係る撮像部110の回動状態を検出する回動検出部170について説明する。
次に、図9を参照して、本実施形態に係る撮像装置10の制御方法について説明する。図9は、本実施形態に係る撮像装置10の制御方法を示すフローチャートである。
次に、図10及び図11を参照して、アダプタ20の装着の有無に応じて、表示部130による表示動作の設定を制御する方法の具体例について詳述する。図10は、本実施形態に係る通常撮像時における反転表示機能の有効状態を示す説明図であり、図11は、本実施形態に係る全周囲撮像時における反転表示機能の無効状態を示す説明図である。
次に、撮像部110にアダプタ20を装着して全周囲撮像するときに、全周囲撮像光学系21の光学特性に応じて、撮像部110による撮像動作の設定を制御する方法の具体例について詳述する。
まず、全周囲撮像時の撮像画像の画角の最適化について説明する。撮像装置10の制御部150は、アダプタ20が撮像部110に装着されたことを検出すると、アダプタ20の全周囲撮像光学系21の光学特性に応じて、全周囲撮像により得られる撮像画像(即ち、環状画像30)の画角を制御する。全周囲撮像に適した画角の制御方法としては、以下に詳述するように、例えば、(1)ズーム位置による画角制御と、(2)画像サイズによる画角制御がある。
撮像部110に装着されたアダプタ20の全周囲撮像光学系21の光学特性設計によって、撮像素子112の撮像面に投影される被写体像のサイズは一意に決定する。しかし、撮像装置10がズーム機構を有している場合、撮像光学系111のズームレンズの位置(以下、ズーム位置又はズームポジションという。)によって撮像素子112に投影される被写体像のサイズが変化してしまう。
アダプタ20装着時に、最大画角となるようにズームポジションを移動させる画角制御方法について説明する。まず、撮像光学系111のズーム機構により撮像画像が最大画角となるときのズームポジション(例えばWide端)において、全周囲撮像光学系21及び撮像光学系111を介して撮像素子112に投影される被写体像が欠けることなく、かつ、該被写体像のサイズが最大になるように、アダプタ20の全周囲撮像光学系21の光学特性を予め設計しておく。そして、撮像部110に対するアダプタ20の装着が検出されたとき、制御部150は、ズームモータ114aを制御して、ズームレンズの位置(ズームポジション)をWide端に移動させる。これによって、その全周囲撮像光学系21の光学特性に応じて、環状画像30の画角を最適化(最大画角)できる。
次に、アダプタ20装着時に、予め設定した最適な画角となるようにズームポジションを移動させる画角制御方法について説明する。まず、全周囲撮像光学系21及び撮像光学系111を介して撮像素子112に投影される被写体像が欠けることなく、かつ、該被写体像のサイズが最大になるようなズームポジションを、予め撮像装置10の記憶部に記憶しておく。当該ズームポジションは、全周囲撮像光学系21の光学特性に応じた最適なズームポジションである。そして、撮像部110に対するアダプタ20の装着が検出されたとき、制御部150は、ズームモータ114aを制御して、ズームレンズの位置(ズームポジション)を、上記の予め記憶されたズームポジションに移動させる。これによって、その全周囲撮像光学系21の光学特性に応じて、環状画像30の画角を最適化できる。
次に、アダプタ20装着時に、撮像画像の画像処理により最適画角を求める画角制御方法について説明する。まず、撮像部110に対するアダプタ20の装着が検出されたとき、制御部150は、ズームポジションをTele端からWide端へ徐々に移動させながら、撮像画像に対する画像処理技術を用いて、全周囲撮像光学系21及び撮像光学系111を介して撮像素子112に投影される被写体像のサイズを評価する。そして、制御部150は、当該被写体像のサイズが最大となり、かつ、当該被写体像が欠けないようなズームポジションを求め、当該ズームポジションに固定する。例えば、制御部150は、全周囲撮像により得られる環状画像30のサイズが画枠いっぱいの状態(欠けている状態)から、当該画枠内に収まったところで、ズームポジションを固定する。このように実際に撮像された環状画像30を画像処理することによって、装着される全周囲撮像光学系21の種類にかかわらず、環状画像30が最大となり、かつ、欠けることがないように、撮像画像の画角を最適化できる。
デジタルスチルカメラ等の撮像装置10は、記録部により記録される撮像画像の画像サイズを変更可能であり、複数の画像サイズの記録に対応している。ここで、画像サイズは、撮像画像のピクセル数(例えば、画像全体のピクセル数、画像の縦横のピクセル数)で表される。例えば、撮像画像(動画)の縦横のピクセル数は、1920×1080ピクセル、1280×720等がある。撮像装置10の制御部150は、記録する撮像画像の画像サイズを、複数の画像サイズの中から、ユーザにより指定された1の画像サイズ、若しくは、自動的に選択した1の画像サイズに設定する。
次に、全周囲撮像時のフォーカスポジションの最適化と、オートフォーカス制御について説明する。撮像装置10の制御部150は、アダプタ20が撮像部110に装着されたことを検出すると、アダプタ20の全周囲撮像光学系21の光学特性に応じて、撮像光学系111の焦点位置(フォーカスポジション)を制御して、全周囲撮像により得られる撮像画像(即ち、環状画像30)のピントを合わせる。本実施形態に係る撮像装置10のフォーカス制御方法は、以下に詳述するように、例えば、(1)通常撮像時、(2)全周囲撮像時とで異なる。
まず、撮像装置10の撮像部110にアダプタ20を装着せずに、通常の撮像光学系111のみを用いて通常撮像するときのオートフォーカス制御について説明する。
撮像装置10の撮像部110にアダプタ20を装着して、アダプタ20の全周囲撮像光学系21及び通常の撮像光学系111の双方を用いて全周囲撮像するときのフォーカス制御について説明する。
全周囲撮像光学系の種類としては、例えば、図6で示したような二回反射タイプの全周囲撮像光学系21と、図15に示すような一回反射タイプの全周囲撮像光学系25がある。後者の一回反射タイプの全周囲撮像光学系25は、被写体からの光を反射する反射面26を1つだけ具備しており、当該反射面26は、中心軸に対して回転対称な形状を有する凸面鏡で構成される。
次に、図6で示したような二回反射タイプの全周囲撮像光学系21を具備するアダプタ20を用いた場合のフォーカス制御について説明する。
次に、全周囲撮像時の露出制御の最適化について説明する。撮像装置10の露出制御としては、自動露出(AE)制御が一般的である。このAE制御では、撮像される被写体や、撮像装置10の周辺環境に応じて、AE制御のパラメータを変更する変えることによって、被写体に合った露出制御を実行される。
次に、全周囲撮像時の撮像補助機能の無効化について説明する。撮像補助機能は、撮像部110による撮像動作を補助するための機能である。この撮像補助機能は、例えば、撮像中のユーザの手振れによる撮像画像の乱れを補正する補正手振れ補正機能や、撮像画像中の人物の顔を検出する顔検出機能などを含む。
次に、全周囲撮像時に、操作部160に対するユーザ操作を制御する操作制御の設定の最適化について説明する。上述したように、本実施形態に係る撮像装置10は、アダプタ20が装着されたときに、撮像動作の設定(画角、フォーカス、露出等の撮像パラメータ)や表示動作の設定を、全周囲撮像光学系21の光学特性に合わせて最適化する。しかし、このように各種の設定を最適化したにもかかわらず、ユーザの誤操作により、当該最適な設定を維持できなくなる場合も考えられる。
次に、図16を参照して、本発明の第2の実施形態に係る撮像装置11について説明する。図16は、本発明の第2の実施形態に係る撮像装置11を示す斜視図である。
以上、本発明の好適な実施形態に係る撮像装置10、11と、その制御方法について説明した。本実施形態によれば、撮像装置10、11の撮像部110に対して、全周囲撮像光学系21を備えた着脱式のアダプタ20を着脱自在である。従って、アダプタ20を装着しないときには、撮像装置10、11は、撮像光学系111を用いて、一方向の被写体を撮像する通常撮像動作を行うことができる。一方、アダプタ20を装着したときには、撮像装置10、11は、全周囲撮像光学系21及び撮像光学系111を用いて、全方向(撮像装置10、11の周囲の全方向)の被写体を撮像する全周囲撮像動作を行うことができる。
