デジタル・イメージ処理装置は、さらに、レンズ、シャッター、絞り、およびフォーカス・モータを備えるフォーカス・アセンブリなどの光学センサに物体像を供給することができる焦点合わせ手段も含むことができる。光学センサは、電荷結合素子(CCD)、電荷注入素子(CID)、光学相補型金属酸化シリコン(CMOS)アレイ、光学バイポーラ接合型トランジスタ(BJT)アレイ、フォトゲート・アレイ、またはフォトダイオード・アレイなどの複数の光学センサのうちの少なくとも1つである。
また、さまざまな実施形態では、複数の計算要素の第1の固定されたアーキテクチャおよび第2の固定されたアーキテクチャは、線形フィルタ処理、非線形フィルタ処理、メモリ、加算、乗算、複素乗算、減算、同期化、キュー処理、オーバー・サンプリング、アンダー・サンプリング、適応、構成、再構成、制御、入力、出力、およびフィールド・プログラマビリティなどの対応する機能を備えるアーキテクチャなどの複数の特定のアーキテクチャから選択することができる。
前記のことから、多数のバリエーションおよび修正が、本発明の新規性のある概念の精神と範囲から逸脱することなく、実施することが可能であることがわかる。本明細書で例示している特定の方法および装置に関する制限はいっさい意図しておらず、またそのように推論されることはないことは理解されるであろう。もちろん、付属の請求項は、請求項の範囲内に収まるそのようなすべての修正を対象とするものとする。
