次に、規格撮影支援装置1の規格撮影モードの処理の流れについて図12を参照(適宜図1、図7(a)から図7(c)参照)して説明する。規格撮影支援装置1は、制御部20の撮影モード選択部22によって、規格撮影モードボタンB02を表示操作部10に表示させ(ステップS1)、規格撮影を実行する指示が入力されたか否かを判別する(ステップS2)。規格撮影以外を実行する指示が入力された場合(ステップS2:No)、撮影モード選択部22は、その他の撮影モードの設定を行う(ステップS9)。その他の撮影モードは、例えば通常撮影モード等を指す。
次に、図12のステップS7Aの流れについて図13を参照(適宜図1、図8(a)および図8(b)参照)して説明する。撮影モード選択部22は、表示操作部10に特定部位設定部81として5つのボタンを表示させる(ステップS12)。ユーザが、表示操作部10の特定部位設定部81の中から任意のボタンを操作して撮像部位を特定すると、撮影モード選択部22は、表示操作部10に、特定された撮像部位に対応したボタンを識別できるように表示させる(ステップS14)。そして、ユーザが受診者の撮像部位を撮像すると、撮影モード選択部22は、このときの撮像部位と撮像画像を関連付ける(ステップS16)。
一方、9枚法の撮像部位の手動設定(ステップS7B)は、その流れが図13に示した流れと同様なので説明を省略する。なお、9枚法の撮像部位の手動設定においては、表示操作部10に特定部位設定部81のボタンとして9つのボタンが表示される。
次に、図12のステップS8Aの流れについて図14を参照(適宜図1、図8(c)および図8(d)参照)して説明する。規格撮影支援装置1は、制御部20の撮像部位判定部23によって、姿勢検出センサ5の検出結果を取得し(ステップS21)、姿勢検出センサ5の検出結果から撮像部位を判定し(ステップS22)、判定された撮像部位の情報を撮影モード選択部22に出力する。なお、撮像部位判定部23は、正面撮影時に取得した姿勢検出センサ5の検出結果を基準値として記憶する。
一方、9枚法の撮像部位の自動設定(ステップS8B)は、その流れが図14に示した流れと同様なので説明を省略する。なお、9枚法の撮像部位の自動設定においては、表示操作部10に特定部位情報報知領域71として9つの領域が表示される。
次に、図15を参照して、第2実施形態に係る規格撮影支援装置1Bについて説明する。なお、図1に示す規格撮影支援装置1と同じ構成には同じ符号を付して説明を省略する。規格撮影支援装置1Bは、測距手段60を備えていると共に、制御部20Bに拡大率設定部28を備えている点が規格撮影支援装置1と相違する。
測距手段60は、例えば測距センサ(超音波方式、レーザ光方式)、画像認識手段(カメラ、画像処理部、制御部等)、またはAF(オートフォーカス)機構(制御部を含む)などを指す。
測距手段60が測距センサである場合、規格撮影支援装置1と撮像対象との間の距離とは、測距センサと撮像対象との間の距離である。
測距手段60が画像認識手段である場合、規格撮影支援装置1と撮像対象との間の距離は、カメラのレンズと撮像対象との間の距離である。
測距手段60がAF機構(制御部を含む)である場合、規格撮影支援装置1と撮像対象との間の距離は、カメラのレンズと撮像対象との間の距離、または、AFセンサと撮像対象との間の距離等を指す。
測距手段60は、測定した距離を画像拡大率調整部26(拡大率設定部28)に出力する。
図16(b)は、領域用拡大率テーブルを示す図である。この領域用拡大率テーブルは、撮影可能距離を10mmごとの領域に区切って領域用拡大率を予め格納している。この例では、撮像部2の撮影可能距離が300~500mmであり、また、基準となる拡大率が8倍であるものとした。この領域用拡大率テーブルにおいて、領域1(距離Lが300~310mmの場合)の領域用拡大率は、8×1である。領域11(距離Lが400~410mmの場合)の領域用拡大率は、8×0.904である。領域21(距離Lが500~510mmの場合)の領域用拡大率は、8×0.817である。
画像拡大率調整部26は、撮像部位に応じて、基準となる拡大率に基づいて撮像画像の拡大率を調整する。規格撮影において5枚法の撮像画像の基準となる拡大率は、図17(a)に示すように8倍であるものとする。規格撮影において9枚法の撮像画像の基準となる拡大率は、図17(b)に示すように、撮像部位に応じて12倍または16倍であるものとする。
拡大率設定部28は、撮像部位に応じた基準となる拡大率を補正するために、撮像部位に応じた補正値を用いる。図17(a)に示す補正値1~補正値5は、口腔内の部位1~部位5に対する補正値である。また、9枚法の場合、図17(b)に示す補正値1~補正値9は、口腔内の部位1~部位9に対する補正値である。
これに対して、第2実施形態に係る規格撮影支援装置1Bは、当該規格撮影支援装置1Bと撮像対象との間の距離に応じて、各撮像画像の拡大率を補正して設定するので、複数の撮像画像どうしの間で拡大率の統一を図る作業の手間を低減することができる。
このようにすることで、たとえ測距手段60を有していなくても、複数の撮像画像どうしの間で拡大率の統一を図る作業の手間を従来よりも低減するこができる。
