Title (EN) PROJECTOR AND DRIVE CONTROL METHOD
(FR) PROJECTEUR ET PROCÉDÉ DE COMMANDE D'ENTRAÎNEMENT
(JA) プロジェクタ及び駆動制御方法
Abstract:
(EN) This projector comprises: a plurality of light sources; a plurality of phosphor wheels on which are fixed a plurality of pieces of phosphor, and which emit light as excitation light in response to light from a light source; a synthesizing optical system that synthesizes light emitted by the plurality of phosphor wheels; and a phosphor rotation control unit that controls the rotation of the plurality of phosphor wheels in such a manner that the timing with which the amount of light generated by the phosphor wheel reaches a minimum is different for each of the plurality of phosphor wheels.
(FR) L'invention concerne un projecteur comprenant : une pluralité de sources de lumière ; une pluralité de roues à luminophore sur lesquelles sont fixés une pluralité de morceaux de luminophore et qui émettent de la lumière sous forme de lumière d'excitation en réponse à la lumière provenant d'une source de lumière ; un système optique de synthèse qui synthétise la lumière émise par la pluralité de roues à luminophore ; et une unité de commande de rotation de luminophore qui commande la rotation de la pluralité de roues à luminophore de telle sorte que le cadencement avec lequel la quantité de lumière générée par la roue à luminophore atteint un minimum est différente pour chacune de la pluralité de roues à luminophore.
(JA) プロジェクタは、複数の光源と、光源からの光を励起光にして光を発光する、複数片の蛍光体が円弧状に固定された複数の蛍光体ホイールと、複数の蛍光体ホイールで発光された光を合成する合成光学系と、蛍光体ホイールが発光した光の量が最小値となるタイミングが複数の蛍光体ホイール毎にそれぞれ異なるように複数の蛍光体ホイールの回転を制御する蛍光体回転制御部とを有する。
