Abstract

La présente invention comprend les éléments suivants : une unité de détermination du rythme circadien (12) pour déterminer le rythme circadien d'un utilisateur sur la base d'informations indiquant les zones de temps de sommeil quotidien de l'utilisateur ; une unité de réglage du moment d'irradiation lumineuse (13) pour régler le moment d'irradiation lumineuse sur la base du rythme circadien déterminé ; et une unité de commande d'irradiation lumineuse (15) pour commander un rétroéclairage (22) de manière à irradier un écran d'affichage d'un terminal avec une lumière d'une intensité prédéterminée ou supérieure pendant un temps prédéterminé lorsque le moment d'irradiation lumineuse réglé est atteint, afin qu'un effet maximal d'ajustement du biorythme par l'irradiation lumineuse puisse être obtenu d'une manière adaptée aux utilisateurs individuels en amenant l'écran d'affichage du terminal à être irradié par la lumière d'une intensité prédéterminée ou plus élevée à des moments d'irradiation lumineuse fixés en fonction des différents rythmes circadiens des utilisateurs respectifs.
