Abstract

　スコープ等の撮像装置に応じた色変換処理を実現するとともに、色再現の精度向上を可能とする画像処理装置を提供することを目的とする。複数の色変換部（１１５）と、入力映像信号に対して色変換処理を実行する指定色変換手段として、複数の色変換部（１１５）のうち少なくとも１つを選択するための指標を取得する情報取得部（２５０）と、前記指標に基づいて、複数の色変換部（１１５）のうち少なくとも１つを前記指定色変換手段として選択する選択部（２５１）と、を具備し、複数の色変換部（１１５）は、前記入力映像信号に対して線形変換によって色変換処理を行う線形マトリックス変換部（２０２）と、前記入力映像信号に対して非線形変換によって色変換処理を行うテーブル変換部（２０３）とを有する画像処理装置（１）を採用する。
