  • the information processing apparatus further includes a reception unit that receives a user instruction to change the image quality to a predetermined image quality. Therefore, an image with a predetermined image quality can be displayed promptly according to the user's request.
  • step S4 in FIG. 3 the determination is made based on either one of the forces shown in the example of determining whether or not the image quality is changed based on the use history and the iris state. It is also good. Further, the determination may be made in consideration of other conditions.
  • an example is shown in which the initial value of image quality and the rate of change are determined based on the usage history and the surrounding environment in step S6 of FIG.
  • a configuration may be made based on the determination. Moreover, it is good also as a structure which considers other conditions and determines.
  • the interruption instruction is received in step S8 in FIG. 3 is shown, but a configuration in which the interruption instruction is received at another timing may be employed.

  • step S3 detection of iris state
  • step S4 determination of whether to change the image quality
  • step S5 detection of surrounding environment
  • step S6 determination of initial value and change rate
  • step S6 of FIG. 3 the method for determining the initial value and the rate of change described in step S6 of FIG. 3 is an example. Prefer to determine the term value and the rate of change.
  • the example in which the image quality is changed according to the change rate determined before the start of the image quality change is shown.
  • the change rate is changed over time. It is good also as composition changed.
  • the iris state may be analyzed based on the detection result of the iris sensor 117, and the degree of eye fatigue may be estimated to change the rate of change over time.
  • the present invention can be similarly applied to a wearable display having an image display unit on both sides in the example in which the image display unit is provided on only one side.
  • present invention can be similarly applied to shapes other than the wearable display 100 described in the present embodiment.

Abstract

La présente invention concerne un affichage portable qui comprend une unité d'affichage pour afficher une image, une unité de reconnaissance pour reconnaître l'historique d'utilisation de l'unité d'affichage, et une unité de détermination pour déterminer le taux de variation de la qualité d'image selon l'historique d'utilisation. Lors de l'affichage d'une image de qualité correspondant aux caractéristiques des yeux de l'utilisateur, la consommation d'énergie est réduite et une utilisation à long terme est réalisée. L'unité de détermination peut déterminer la valeur initiale utilisée lorsque la qualité d'image est variée en fonction de l'historique d'utilisation. L'affichage portable peut en outre comprendre une unité de détection pour détecter l'environnement ambiant de l'unité d'affichage. L'unité de détermination peut déterminer le taux de variation d'au moins un parmi la densité, le ton, la netteté et la brillance de l'image en tant que qualité d'image. L'unité de reconnaissance peut reconnaître au moins un parmi le nombre d'utilisations en tant qu'historique d'utilisation et temps d'utilisation total de l'unité d'affichage. L'unité de reconnaissance peut reconnaître en tant qu'historique d'utilisation le temps écoulé depuis l'utilisation précédente de l'unité d'affichage jusqu'à l'utilisation présente. L'affichage portable peut en outre comprendre une unité de réception pour recevoir une commande d'utilisateur afin de varier la qualité d'image en une qualité d'image prédéterminée.
