Abstract
Description
特許文献1に記載の技術では、撮影装置の撮影範囲中に、互いに異なる複数の映像領域を設定し、その中の一つの領域の映像を記録する。また、特許文献1に記載の技術では、記録する映像の領域を複数の領域の中で変更する(切り替える)ことができる。これにより、例えば、撮影装置を固定した状態のままで、撮影映像中の複数の被写体の各々についてズームアップした映像を得ることができる。
ここで、撮影条件は、基準映像内の合焦位置、露光量、及びホワイトバランスのうちの少なくとも一つであってもよい。
ここで、位置情報は、過去に実施された設定工程にて設定された設定領域の位置情報、及び、ユーザの操作に基づいて決められた設定領域の位置情報のうちの少なくとも一つを含んでもよい。
さらに、変更処理は、中止条件を満たす設定領域の設定映像の表示を中止して表示数を減らす処理を含んでもよい。
本実施形態は、図1~図3に示す撮影装置10を用いた映像の表示方法に関する。ただし、以下に説明する実施形態は、本発明の理解を容易にするために挙げた一例に過ぎず、本発明を限定するものではない。すなわち、本発明は、その趣旨を逸脱しない限りにおいて、以下に説明する実施形態から変更又は改良され得る。また、本発明には、その等価物が含まれる。
撮影装置10は、例えば、映像を撮影するデジタルカメラである。
ここで、「映像」とは、特に断る場合を除き、ライブ映像(ライブビュー画像)、すなわちリアルタイムで撮影される映像を意味する。また、本実施形態における映像は、主として動画像である。すなわち、撮影装置10は、所定のフレームレートで動画像を撮影する。
撮影レンズ14は、図3に示すように、光学ユニット17、絞り20、ズーム用駆動部21、フォーカス用駆動部22、及び絞り駆動部23を含む。
光学ユニット17は、ズーム用の光学機器18(例えば、ズームレンズ)を含む。光学機器18を光軸L1の方向に動かすことにより、撮影装置10の撮影領域が拡大又は縮小してズームが変わる。つまり、撮影装置10は、光学機器18による光学ズーム機能を備える。
なお、本実施形態の撮影装置10は、光学ズーム機能とともに、映像中の被写体を電子処理にて拡大する電子ズーム(デジタルズーム)機能を備える。
なお、本実施形態の撮影装置10は、オートフォーカス(AF)機能を備える。すなわち、映像撮影中、ユーザが所定の操作(例えば、映像記録開始の指示操作)を行うと、フォーカス用駆動部22が作動して光学機器19を動かす。この結果、映像中の所定部分に合焦するように合焦位置が自動調整される。
ちなみに、撮影装置10に設けられる光学ユニット17は、1つに限定されず、互いに画角が異なる複数の光学ユニット17が備えられてもよい。
撮影装置本体12は、図1及び図2に示すように、操作ボタン30を含む操作部を備える。また、撮影装置本体12の上面には、操作部の1つであるレリーズボタン26が配置されている。レリーズボタン26が押されると、撮影装置10が撮影する映像、あるいは、その中から切り出された映像(厳密には、後述の記録映像)の記録が開始される。
なお、映像の記録開始指示にかかるユーザの操作は、レリーズボタン26の押下げに限定されず、後述する背面のディスプレイ28において所定位置をタッチする操作でもよい。
また、背面のディスプレイ28は、映像以外の情報を表示することができ、例えば撮影に関するアドバイス又は提案情報等を表示する(図18参照)。
また、プロセッサは、SoC(System on Chip)等に代表されるように、コントローラ47及び映像処理部48を含む制御部46全体の機能を1つのIC(Integrated Circuit)チップで構成してもよい。
以上に挙げた各プロセッサのハードウェア構成は、半導体素子などの回路素子を組み合わせた電気回路(Circuitry)で実現してもよい。
なお、記録形式は、特に限定されず、自由に決めることができる。
なお、電子手振れ補正オンである間は、抽出映像が基準映像となる。
なお、内部メモリ50及びメモリカード54は、撮影装置本体12とは別の機器(外部)に備えられてもよい。その場合、制御部46は、有線又は無線によって外部の記録媒体に対して記録映像を記録してもよい。
バッファメモリ56は、制御部46のワークメモリとして機能する。
撮影装置10は、基準映像から切り出される記録映像を記録媒体に記録する。また、撮影装置10は、基準映像における切り出し領域を変えることで記録映像を切り替える(スイッチする)ことができる。このような機能に関して、図5を参照しながら説明する。
なお、図5では、説明の便宜上、映像中の被写体の図示を省略している。
標識fは、基準映像中における設定領域Arの位置を示し、設定領域Arの境界を含んでいる。設定領域Arの境界は、設定領域Arとその周辺とを識別する(見分ける)ために設定される。
以下では、有色の矩形枠からなる標識fを例に挙げて説明することとする。
識別情報は、制御部46が所定の付与ルールに則って個々の標識fに対して個別に付与される情報である。識別情報が標識fと共に表示されることにより、ユーザは、各標識fを見分けることができる。
なお、識別情報は、特に限定されず、番号、文字又は記号でもよく、あるいは標識f毎に分けられた標識fの表示色でもよい。番号を識別情報とする場合には連番であることが望ましい。
図5に示すケースでは、記録領域Apの位置を示す標識fの表示色及び太さが、それ以外の標識fとは異なっている。
なお、基準領域が決まるとは、記録開始指示の受け付け時点で基準領域が一度決まることを意味している。また、基準領域が決まった後でも、ユーザは自由に基準領域を変更することが可能である。ちなみに、ユーザが基準領域を変更した際は、後述するように、設定領域の位置を被写体の位置に応じて変更させることが好ましい。
なお、記録映像は、基準映像の画角よりも小さい画角の映像ではあるが、基準映像が高画質であれば(例えば、画素数が1000万以上であれば)、十分に高画質な映像となる。
基準映像の画素数は、特に限定されないが、その下限は、1000万以上であるのがよく、6000万以上であるのがより好ましい。また、画素数の上限は、10億以下であるのがよく、5億以下であるのがより好ましい。画素数が上記の下限より大きいと、記録映像の視認性が担保される。また、画素数が上記の上限より小さいと、基準映像のデータ量が低減し、制御部46による処理の高速化が図られる。
そして、映像記録中にユーザが記録領域Apを別の設定領域Ar(例えば、識別情報「2」の標識fによって囲まれた設定領域Ar)に変更する指示を行うと、記録領域Apが再選択されて記録映像が切り替わる。
このように本実施形態では、映像記録中に、記録領域Apの再選択によって記録映像を切り替えることができる。これにより、複数存在する被写体のそれぞれに対して個々のカメラを設置する必要なく、各被写体のズーム映像を撮影することができる。
ただし、これに限定されず、切り替え前の記録映像と、切り替え後の記録映像とを結合せずに、それぞれ別ファイルデータとして記録してもよい。また、基準映像及び後述の待機領域も別ファイルデータとして記録してもよい。
また、移動している被写体を追尾する設定領域Arが記録領域Apである場合には、移動している被写体の映像を記録することができる。
撮影装置10の制御部46が実行する処理フロー(以下、映像表示フロー)について、図10を参照しながら説明する。
なお、上記の調整は、撮影装置10の出荷前に装置メーカー側で行われてもよい。また、ユーザは、一度調整した解像度及びアスペクト比等を見直すために、これらの値を撮影装置10の起動後に再調整することが可能である。
選択工程の実施に際して、制御部46は、複数の設定領域Arのそれぞれの映像(以下、「設定映像」という。)をディスプレイに表示するとよい。この場合、ユーザは、複数の設定領域Arのそれぞれについて、設定映像を確認することができる。
また、前述のように、記録工程の開始の契機となる記録開始指示の受け付け時点で基準領域が決定する。
その後に撮影終了指示があるか、又は撮影装置10の電源がオフになると(S011)、その時点で映像表示フローが終了する。
映像表示フロー中の設定工程について説明する。
本実施形態では、設定工程の実行に際して、図11に示す第1のUI(User Interface)画面101が背面のディスプレイ28が表示される。ユーザは、設定領域Arの設定パターンとして「記録パターン」又は「自動設定パターン」のいずれかを選択し、UI画面101上のボタンBt1、Bt2のうち、選択したパターンを示すボタンを押す。
本実施形態では、自動設定パターンが選択されると、図11に示すように第3のUI画面103が表示される。ユーザは、予め用意された複数の自動設定パターンのいずれかを選択し、第3のUI画面103上のボタンBt6、Bt7、Bt8のうち、選択したパターンを示すボタンを押す。自動設定パターンとしては、例えば、「シーン認識パターン」、「被写体検出パターン」及び「AF位置特定パターン」が選択可能である。なお、自動設定パターンの場合、設定工程の開始時点では、各々の設定領域Ar同士が重ならず、互いに重畳しない状態で標識fを表示するのが好ましい。これにより、複数の標識fを識別し易くなり、設定工程における設定領域Arの設定が容易になる。
前回使用パターンが選択された場合、制御部46は、前回(直前)の映像表示フローにおける設定工程で設定された設定領域Arの位置情報を読み出す。この位置情報は、前回の映像表示フローの設定工程で設定された複数の設定領域Arのそれぞれの位置を示しており、例えば撮影装置10の内部メモリ50に記憶される。記憶された位置情報は、撮影装置10の電源オフ後にも保持されると好ましい。
プリセットパターンが選択された場合、制御部46は、予め定められた定型の配置パターンで配置される設定領域Arの位置情報を読み出す。定型の配置パターンは、撮影装置10に事前登録されている、又は購入後のプログラム更新時等にて新規に登録される。
なお、プリセットパターンの種類数、及び各プリセットパターンにおける設定領域Arの個数及び配置位置は、特に限定されず任意に決められる。
ユーザ入力パターンが選択された場合、制御部46は、ユーザの操作に基づいて決められた設定領域Arの位置情報を読み出す。ここでのユーザの操作は、設定領域Arの位置を登録するための入力操作であり、設定工程の前段階(例えば、パターンに関する初期登録の段階)で行われる。上記の入力操作は、例えば、図14に示すパターン登録用の入力画面105を通じて行われる。ユーザは、入力画面105に表示された領域設定用の標識fxの内側領域をタッチアンドドラッグする。これにより、ドラッグ後の標識fxの表示位置が設定領域Arの位置として登録される。
シーン認識パターンが選択された場合の設定工程では、制御部46は、基準映像に基づいて基準映像の撮影シーンを認識する。基準映像の撮影シーンは、例えば基準映像として撮影される風景、イベント、被写体の種類、場面(例えば、日中の景色であるか夜景であるか)、及び、状況(例えば、天気など)等である。
被写体検出パターンが選択された場合の設定工程では、制御部46が、基準映像中の被写体を検出し、検出された被写体の位置に設定領域Arを自動的に設定する。基準映像中の被写体は、基準映像中における風景以外の被写体であって、制御部46が検出可能なものであり、例えば人、動物及び乗物等が含まれる。
被写体を検出する場合には、公知のテンプレートマッチング技術を適用してもよい。例えば、被写体の画像をテンプレート画像として予め記憶し、テンプレート画像と基準映像中の各部分とを照合し、テンプレート画像と類似する映像を被写体として検出してもよい。あるいは、機械学習によって映像中の被写体を認識させるモデルを構築し、そのモデルを利用して基準映像中の被写体を検出してもよい。被写体認識モデルのアルゴリズムとしては、YOLO(You Only Look Once)又はR-CNN(Region with Convolution Neural Network)等の公知のアルゴリズムが利用可能である。
AF位置特定パターンが選択された場合の設定工程では、制御部46が、基準映像中、撮影装置10のフォーカスを決めるための特徴が基準を満たす位置を特定し、特定された位置に設定領域Arを自動的に設定する。フォーカスを決めるための特徴とは、例えば、基準映像内の合焦位置を決めるための特徴である。具体例を挙げると、オートフォーカスが位相差AF(Auto Focus)方式である場合には、位相差が上記の特徴に該当する。また、オートフォーカスがコントラストAF方式である場合には、複数の画素間のコントラストが上記の特徴に該当する。なお、AF方式は、指向性光を用いたAF方式でもよいし、あるいは、DFD(Depth from defocus)を用いたAF方式でもよい。
また、基準映像中に被写体が検出されず、基準映像内に適切な設定領域Arの設定位置が見つからない場合、基準映像の中央付近に設定領域Arを設定してもよい。
以下、設定工程における候補Acの設定手順について説明する。
設定工程において、制御部46は、基準映像の各画素の特徴(例えば、画素値)に基づいて、基準映像に特徴箇所が存在するか否かを判定する。特徴箇所とは、基準映像の中で視覚的変化が生じている箇所(被写体として検出されるものを除く)であり、例えば、背景映像の中で動きがある箇所、並びに、色及び明るさ等が変化する箇所である。具体例としては、滝のような流れがある箇所、イルミネーションのような光が点灯又は点滅する箇所、及び、電光掲示板のように表示される文字及び画像等が切り替わる箇所等が挙げられる。
なお、図16に示す基準映像では、例えば、図中の左上部分に現れている電飾が特徴箇所に該当する。
映像表示フロー中の表示工程について以下に詳しく説明する。
設定工程にて設定領域Arが設定されると、制御部46が表示工程を開始する。その後、制御部46は、記録工程が終了するまで(厳密には、撮影が終了するまで)、表示工程を続行する。
さらに、基準映像中に前述の特徴箇所が存在する場合の表示工程では、特徴箇所の位置を示す候補標識Kが、基準映像中に標識fと共に表示される。
サブ画面G2は、メイン画面G1と比べて小さい画面であり、表示画面の縦方向又は横方向に沿って列状に並んでいる。各サブ画面G2は、記録映像又は一つの待機映像を表示する。各サブ画面G2のアスペクト比は、記録映像及び待機映像の各々のアスペクト比と同じ値に設定されていると好ましい。
情報表示画面G3は、映像以外の文字情報を表示する画面であり、例えば、図18に示すように、映像記録に関するアドバイスを表示する。
また、ユーザにとって標識fを見え易くする目的から、基準映像中、標識f内の映像を強調表示すると、より好ましい。例えば、図18に示すように、基準映像中、標識f内(すなわち、設定領域Arの境界内)の映像以外の明度を下げたりグレーアウト表示させたりしてもよい。
なお、電子手振れ補正に伴って設定領域Arの位置を調整する機能については、ユーザの操作に応じてオンオフを自由に切り替えられると好ましい。
例えば、ユーザが第1モードを指定すると、表示工程として、第1表示工程が実施される。第1表示工程では、図18に示すように、基準映像及び設定領域Ar毎の標識fがメイン画面G1に表示され、記録映像及び待機映像がサブ画面G2に表示される。他方、ユーザが第2モードを指定すると、表示工程として、第2表示工程が実施される。第2表示工程では、図19に示すように、記録映像及び待機映像を表示し、且つ基準映像及び設定領域Ar毎の標識fを表示しない。
あるいは、第2表示工程において記録映像と、その他の設定映像とを互いに異なるディスプレイに表示してもよい。例えば、図20に示すように、記録映像を背面のディスプレイ28に表示し、その他の設定映像を電子ビューファインダ29又は撮影装置10に接続された外部モニタ(不図示)に表示してもよい。
また、情報表示画面G3には、ユーザに対する撮影用のアドバイス、及び警告メッセージ等を表示することができる。例えば、記録工程中に露光量又はISO感度等の調整が必要となった場合には、その旨を表示してもよい。
さらに、情報表示画面G3には、上記以外の情報を表示することができる。例えば、現時点で採用されている撮影モード、解像度及びISO感度等の撮影条件に関する現在値、並びに電子ズーム等の各種機能のオンオフ等を表示してもよい。
表示工程において、サブ画面G2の数は、記録映像の解像度及びアスペクト比のうちの少なくとも一方の項目(以下、単に「少なくとも一方の項目」と呼ぶ)に応じて決められる。つまり、サブ画面G2に表示される設定映像の表示数は、少なくとも一方の項目に応じて決められる。
同様に、各サブ画面G2のサイズについても、少なくとも一方の項目に応じて決められる。つまり、設定映像の表示サイズは、少なくとも一方の項目に応じたサイズとなる。
なお、図21に示すケースでは、待機映像の最大表示数が3個である。
なお、図21に示すケースでは、待機領域の数が6個である。
また、被写体が人物である場合には、パターンマッチング等の技術により人物の顔を認識し、顔が認識された人物の重要度を特定し、その特定結果を被写体に関する情報としてもよい。人物の重要度については、例えば、顔が認識された人物の属性(例えば、家族、親戚、知人又は他人)等を判定し、その判定結果から求めることができる。また、検出された被写体が複数ある場合は、被写体のカテゴリ(例えば、人、動物、物又は風景等)によって優先度を決定してもよい。さらに、検出されたタイミングが早い被写体から優先して、優先度を決定してもよい。
なお、被写体に関する情報については、当然ながら、上記以外にも考えられ得る。決定工程において、どのような情報を被写体に関する情報として利用するかについては、ユーザが自由に選べるのが望ましい。
そして、上記の実績に関する情報に基づいて、複数の待機領域の各々の優先度を決定してもよい。例えば、実績に関する情報が、記録領域として選択された回数又は時間である場合、その回数又は時間が多いほど、高い優先度を付与するとよい。
映像表示フロー中の制御工程について説明する。制御工程は、基準領域の変更を抑制するための制御処理を実行する工程であり、少なくとも基準領域の決定後に実施される。つまり、制御処理は、ユーザの記録開始指示の受け付け時点後の基準領域の変更を抑制するための処理である。
上記の制御処理を実行すれば、記録工程の実施中、基準領域に対する各設定領域Arの相対位置が変化するのを防ぐことができる。その結果、各設定領域Arが基準領域から外れて記録映像等の各設定映像が適切に撮影されなくなる状況を回避することができる。
記録工程の実施中、所定の条件が満たされると、制御部46が変更工程を実施する。変更工程は、設定領域Arの映像(すなわち、設定映像)の表示数の変更に関する変更処理を実行する工程である。変更処理の実行により、記録工程の実施中に設定映像の表示数を動的に増やす、又は減らすことができる。
以下、図25に示すフローを参照しながら、記録工程の実施中における処理の流れについて説明する。ちなみに、以降の説明で参照する図26~31では、図示の便宜上、標識f内の映像以外の映像のグレーアウト表示を省略している。
中止条件(1):光学ズーム等によって設定領域Arの少なくとも一部が基準領域からはみ出していること。
中止条件(2):一定時間以上、設定領域Arの設定映像に変化がない、又は設定映像中に被写体が存在しないこと。
中止条件(3):一定時間以上、記録領域として選択されていない設定領域Arであること。
なお、中止条件は、上記の条件(1)~(3)に限られず、上記以外の条件が中止条件に含まれてもよい。
なお、設定映像の表示が中止された設定領域Ar(以下、中止領域という。)に関しては、図30に示すように、メイン画面G1において、中止領域の位置を示す標識fの表示も中止される。
なお、再表示可能な中止領域の設定映像は、直前の中止領域(直近で設定映像の表示が中止された設定領域)の映像に限られない。例えば、今回の撮影期間中における過去数回分の中止領域の映像を再表示可能としてもよい。その場合、撮影装置10には過去数回分の中止領域が記憶され、ユーザは、どの中止領域の設定映像を再表示するかを指定して映像の再表示を指示する。
ステップS042における変更処理では、被写体の数が設定領域Arの数の上限値を超えた旨、及び、設定映像の表示数を減らすことを推奨するメッセージを情報表示画面G3に表示し、又は音声等で再生する。ユーザは、これを契機として設定領域Arの設定を見直し、例えば、記録領域として選択されない期間が最も長い設定領域Ar等、不要な設定領域Arを削除する。この結果、設定映像の表示数が、ユーザが削除した設定領域Arの数だけ減少する。
以上のように本実施形態では、基準映像中の変化(例えば、被写体の追加等)及び中止条件の成立等を契機として変更工程を実施し、設定映像の表示数を適宜変更する。これにより、ユーザは、その時の状況に応じた数の設定映像を容易に確認し、且つ、記録領域となる可能性が低い設定領域Ar等の映像の確認を省略することができる。この結果、ユーザにとっての利便性が向上する。
以上までに説明してきた実施形態は、本発明の表示方法を分かり易く説明するために挙げた具体例であり、あくまでも一例に過ぎず、その他の実施形態も考えられ得る。
上述した実施形態では、撮影装置10が表示装置として各種の映像を表示することとしたが、これに限定されるものではない。例えば、撮影装置10、撮影装置10と有線又は無線にて接続されたカメラコントローラ、及び外付け型の外部ディスプレイ等によって表示装置が構成されてもよい。その場合には、カメラコントローラが、制御部46としての機能を担い、撮影装置10に基準映像を撮影させ、外部ディスプレイに各種の映像を表示させる。また、カメラコントローラは、設定領域Arの設定、記録領域の選択及び再選択(切り替え)、並びに記録映像の記録等を行ってもよい。
光学ズームによって基準領域が変わると、基準領域に対する各設定領域Arの相対位置が変化する。その場合、制御部46が基準領域の変化量を算出し、算出された変化量に基づき、各設定領域Arの位置及びサイズを調整すると好ましい。これにより、基準領域に対する各設定領域Arの相対位置が、ズームの実施前後で維持されるようになる。
ここで、記録工程中にユーザが撮影装置10を動かすことで基準領域を変更した場合、撮影装置10に備えられたジャイロセンサ等の公知の検出センサが撮影装置10の動き(例えば、変位量)を検出するとよい。そして、制御部46が検出された撮影装置10の動きに基づき、各設定領域Arの位置及びサイズを調整すると好ましい。これにより、基準領域に対する各設定領域Arの相対位置が、変更後の基準領域に応じて調整されるようになる。この際、基準領域の変更により基準領域の外に出た設定領域Arは、自動削除されてもよい。
例えば、制御部46は、基準映像をライブビュー画像としてメイン画面G1に表示し、基準領域の中で複数の設定領域Arを設定する。ユーザが複数の設定領域Arの中から記録領域Apを選択し、制御部46が、記録映像を含む複数の設定映像をサブ画面G2に表示する。そして、ユーザがレリーズボタン26を操作する等して記録指示を行うと、制御部46が、記録映像を静止画像として記録媒体に記録してもよい。
