Abstract:
(EN) The present invention enables a luminance difference in an image displayed in an area of interest to be easily recognized without being influenced by the luminance of the periphery of the area of interest. An HDR display (100) is provided with an image processing unit (14) which, when the number of digits of a difference between the luminance center value of the luminance distribution of an area of interest of a display unit (20) and the luminance center value of the luminance distribution of the entire display region is two or more, converts the luminance value of each pixel on the entire screen such that the luminance center value of the luminance distribution of the entire display region approaches the luminance center value of the luminance distribution of the area of interest.
(FR) La présente invention permet de reconnaître facilement une différence de luminance dans une image affichée dans une zone d'intérêt sans qu'elle soit influencée par la luminance de la périphérie de la zone d'intérêt. Un affichage HDR (100) est muni d'une unité (14) de traitement d'image qui, lorsque le nombre de chiffres d'une différence entre la valeur centrale de luminance de la répartition de luminance d'une zone d'intérêt d'une unité (20) d'affichage et la valeur centrale de luminance de la répartition de luminance de la région d'affichage tout entière est d'au moins deux, convertit la valeur de luminance de chaque pixel sur la totalité de l'écran de telle façon que la valeur centrale de luminance de la répartition de luminance de la région d'affichage tout entière s'approche de la valeur centrale de luminance de la répartition de luminance de la zone d'intérêt.
(JA) 注目エリアの周囲の輝度に影響されず、当該注目エリアに表示された画像の輝度差を容易に認識できる。HDRディスプレイ(100)は、表示部(20)の注目エリアの輝度分布の輝度中心値と、表示領域全体の輝度分布の輝度中心値との差の桁数が2桁以上であるとき、上記表示領域全体の輝度分布の輝度中心値を、上記注目エリアの輝度分布の輝度中心値に近づくように画面全体の各画素の輝度値を変換する画像処理部(14)を備える。
