Title (EN) LIGHTING DEVICE AND PROJECTOR
(FR) DISPOSITIF D'ÉCLAIRAGE ET PROJECTEUR
(JA) 照明装置、およびプロジェクタ
Abstract:
(EN) A lighting device according to the present disclosure comprises: a light source; a phase-modulation liquid crystal panel having a plurality of pixels where each pixel modulates the phase of light from the light source; a modulation signal correction unit for correcting the pixel modulation signal for any target pixel among a plurality of pixels on the basis of the pixel modulation signal for at least one peripheral pixel located in the periphery of the target pixel to reduce the amount of deviation from a desired modulation amount for the target pixel; and an application voltage generation unit for generating an application voltage to be supplied to each pixel on the basis of a pixel modulation signal corrected by the modulation signal correction unit.
(FR) Selon la présente invention, un dispositif d'éclairage comprend : une source de lumière; un panneau à cristaux liquides à modulation de phase ayant une pluralité de pixels, chaque pixel modulant la phase de lumière provenant de la source de lumière; une unité de correction de signal de modulation permettant de corriger le signal de modulation de pixel de tout pixel cible parmi une pluralité de pixels sur la base du signal de modulation de pixel d'au moins un pixel périphérique situé dans la périphérie du pixel cible pour réduire la quantité de déviation à partir d'une quantité de modulation souhaitée du pixel cible; et une unité de génération de tension d'application permettant de générer une tension d'application à fournir à chaque pixel sur la base d'un signal de modulation de pixel corrigé par l'unité de correction de signal de modulation.
(JA) 本開示の照明装置は、光源と、複数の画素を有し、各画素ごとに光源からの光の位相を変調する位相変調液晶パネルと、複数の画素のうちの任意の対象画素の周辺に位置する少なくとも1つの周辺画素に対する画素変調信号に基づいて、対象画素における所望の変調量からのずれ量を低減するように、対象画素に対する画素変調信号を補正する変調信号補正部と、変調信号補正部によって補正された後の画素変調信号に基づいて、各画素に印加する印加電圧を生成する印加電圧生成部とを備える。
