Abstract
Description
以下、図1~12を用いて、実施の形態1を説明する。
まず、光線中心と画像の解像度の関係について説明する。ライトフィールドカメラでは、撮像素子で受光した光を電気信号に変換した画素を処理して画像を再構成してリフォーカス画像を生成する場合、光線中心が重要な役割を果たす。光線中心とは、任意の焦点位置に合わせて画像を再構成する仮想撮像面へ、撮像素子から光線方向に従って仮想撮像面に投影した光線の交わる点である。従って、再構成する画像の各画素は、撮像素子から光線方向に従って、仮想撮像面に投影した仮想撮像面上の光線中心のうち、再構成する画像内のそれぞれの画素に近い光線中心を用いて補完する。この時、光線中心の数は、撮像素子の画素数で固定されるため、仮想撮像面上の光線中心が一箇所に固まると、仮想撮像面上の光線中心の混みあいの程度を示す密度が低い領域では再構成時の画像の解像度が低くなってしまう。
実施の形態1において、撮像装置としてライトフィールドカメラを用いて説明する。図1は、実施の形態1にかかるライトフィールドカメラの構成図である。図1において、ライトフィールドカメラ100は、被写体101を撮影する。ライトフィールドカメラ100は、撮像部310と、信号処理部320で構成される。撮像部310は、メインレンズ102、マイクロレンズアレイ103、撮像素子104で構成される。信号処理部320は、LSI(large Scale Integration)などのプロセッサを用いて実現される。
[1-3-1.光線中心の位置]
まず、仮想撮像面105上の光線中心の位置の計算方法について説明する。
マイクロレンズアレイ103の撮像素子104に対する最適な垂直方向の回転角を算出するため、コスト関数を用いて評価を行った。具体的には、マイクロレンズアレイ103の撮像素子104に対する垂直方向の回転角を、0度から30度までの間で0.1度刻みに変化させ、それぞれの回転角に対してコスト関数を用いてコスト値を算出する。算出したコスト値を用いて評価を行い、マイクロレンズアレイ103の撮像素子104に対する最適な垂直方向の回転角を見出した。
次に、コスト値を算出するコスト関数の詳細について説明する。図5は、実施の形態1におけるコスト関数の一例を説明する図である。図5において、仮想撮像面105上に、コスト関数を計算する範囲を特定するための指定範囲をRとし、指定範囲R内に存在するr番目の注目画素P(r)の位置を、
(数7)のコスト関数を用いて、マイクロレンズアレイ103の撮像素子104に対する最適な垂直方向の回転角を見出した。図6から図10を用いて説明する。
以上のように、本開示の撮像装置は、光の進行方向と進行方向に対する強度で構成される光線情報が記録可能な撮像装置であって、メインレンズと、撮像素子と、メインレンズと撮像素子の間に配置され、撮像素子に対して垂直方向に所定の回転角を有するマイクロレンズアレイと、任意の焦点位置の仮想撮像面に、光線情報を用いてリフォーカス画像を生成する信号処理部と、を備える。
