Abstract:
(EN) A clear image is displayed in a wide angle of view by removing the influence of lens distortions included in an ocular optical system by image correction. Table size reduction is achieved without the premise that the distortion occurring in a virtual image plane is rotationally symmetric with respect to the optical axis. Specifically, representative pixels are set discretely on a display surface of a display unit (203), and displacement vectors obtained only at the positions of the representative pixels are retained. Pixel positions other than those of the representative pixels are interpolated by the displacement vector of one or more of the peripheral representative pixels so as to obtain the displacement vectors at all of the pixel positions.
(FR) Selon la présente invention, une image nette est affichée selon un angle de vision large par élimination de l'influence des distorsions de lentille présentes dans un système optique oculaire au moyen d'une correction d'image. Une réduction de taille de table est réalisée sans la prémisse que la distorsion qui se produit dans un plan d'image virtuel, soit symétrique en rotation par rapport à l'axe optique. De façon précise, des pixels représentatifs sont déterminés de manière discrète sur une surface d'affichage d'une unité d'affichage (203) et des vecteurs de déplacement obtenus seulement aux positions des pixels représentatifs sont retenus. Les positions des pixels autres que celles des pixels représentatifs sont interpolées par le vecteur de déplacement d'un ou plusieurs pixels représentatifs périphériques de sorte à obtenir les vecteurs de déplacement à toutes les positions des pixels.
(JA)  接眼光学系に含まれるレンズ歪みの影響を画像補正により除去して、広画角で鮮明な画像を表示する。 虚像面に発生する歪みが光軸に対して回転対称になるという前提には立たないで、テーブルのサイズの削減を実現する。具体的には、表示部203の表示面上に離散的に代表画素を設定し、代表画素の位置においてのみ得た変位ベクトルを保持しておく。そして、代表画素以外の画素位置では、周辺の1以上の代表画素の変位ベクトルで補間することにより、すべての画素位置での変位ベクトルを得るようにしている。
