Abstract

　対象となる第２の撮像素子により撮像して得られた第２のカラー信号を、目標となる第１の撮像素子により撮像して得られるカラー信号に近似する第１のカラー信号へ変換する色変換を決定するための信号処理装置であって、第１の撮像素子の分光特性と第２の撮像素子の分光特性との差異を、カラー信号を構成する複数の色信号に各係る分光特性毎に算出し、その最大値を分光差異値とする分光差異算出部（１０１）と、分光差異値の大きさが判別基準値以下である場合には色変換として線形変換を決定し、分光差異値の大きさが判別基準値よりも大きい場合には色変換として非線形変換を決定する処理判定部（１０２）と、を備えた信号処理装置。
