Abstract

画像表示装置（Ａ）は、液晶パネルなどの表示装置（１）と、バックライトなどの光源（３）と、光源制御部（５）と、入力信号（Ｓ１）に基づいて、表示装置に対する制御を行う信号を出力する映像信号処理部（７）と、光源制御と映像制御とを含む全体を制御する制御部（１１）と、を有している。制御部（１１）は、入力信号（Ｓ１）に基づいて映像を解析する映像解析部（１５）と、解析結果（Ｓ２）を受けて光源の発光量の目標値を設定する目標値設定部（１７）と、目標値（Ｓ３）を受けて光源の制御速度を決定する制御量決定部（２１）であって光源制御部に対して設定輝度（Ｓ５）を通知するとともに、映像信号処理部（７）に対して補償パラメータ（Ｓ４）を出力する制御量決定部（２１）と、を有している。光源制御部（５）は、輝度設定値（Ｓ５）を受けて光源に対して光量制御信号（Ｓ６）を出力する。これにより画像表示における低消費電力化を図るとともに、視覚的に違和感のない表示を行う技術を提供することが可能になる。
