Abstract
Description
図1は、第1の実施形態の画像表示システムの例示的な概略構成図である。図1に示されるように、車両1に装備される画像表示システム10は、ECU11(electronic control unit)を備えている。ECU11は、撮像部12による撮影画像を画像処理して出力画像を生成する。ECU11は、出力画像が表示されるよう、表示部24aを制御する。ECU11は、画像処理装置あるいは表示制御部の一例である。
Y’n=Yn−Yc…(2)
Y’’n=Y’n×α…(9)
PZn=−Y’’n×Scale+PZn…(11)
PZ’m=PZm−PZc…(13)
Y’’m=−PZ’m/Scale…(15)
Y’m=Y’’m×β…(21)
Ym=Y’m+Yc…(23)
第1の実施形態においては、魚眼レンズのパターンが1種類しかない場合について説明した。しかしながら、魚眼レンズ(仮想レンズ)のパターンを1種類に制限するものではなく、複数種類からユーザが任意で選択しても良い。そこで、第2の実施形態では、複数種類から選択可能な場合について説明する。
