Title
(EN) OBJECT DISPLAY DEVICE AND OBJECT DISPLAY METHOD

Abstract
(EN)
Provided is an object display device with which, when a marker cannot currently be detected, a display compensation unit obtains the change in the image in real space displayed on a display unit between the current time and the past when a marker was able to be detected. A virtual object is an object that is displayed on the basis of the position and shape of a marker in the image in real space, so the display position and the display format of a virtual object also change in response to a change in the image in real space. Therefore, on the basis of the change in the image in real space between the past and the current time, a display determination unit (6) determines the current display position and display format of the virtual object from the past display position and display format of the virtual object.

L'invention concerne un dispositif d'affichage d'objet qui, lorsqu'un repère ne peut pas être détecté à l'instant courant, une unité de compensation d'affichage obtient la modification de l'image dans l'espace réel affiché sur une unité d'affichage entre l'instant courant et le passé à un moment où un repère pouvait être détecté. Un objet virtuel est un objet qui est affiché sur la base de la position et de la forme d'un repère sur l'image dans l'espace réel afin que la position d'affichage et le format d'affichage d'un objet virtuel varient également en réponse à une modification de l'image dans l'espace réel. Par conséquent, selon la modification de l'image dans l'espace réel entre le passé et l'instant courant, une unité de détermination d'affichage (6) détermine la position d'affichage et le format d'affichage courants de l'objet virtuel à partir de la position d'affichage et du format d'affichage antérieurs de l'objet virtuel.

 オブジェクト表示装置では、現在においてマーカを検出できなかった場合に、マーカを検出できていた過去と現在との間における、表示部に表示される現実空間の画像の変化が表示補完部により取得される。仮想オブジェクトは、現実空間の画像におけるマーカの位置及び形状に基づき表示されるものであるので、仮想オブジェクトの表示位置及び表示態様も、現実空間の画像の変化に応じて変化すべきものである。このため、表示決定部6は、当該過去と現在との間における現実空間の画像の変化に基づき、当該過去における仮想オブジェクトの表示位置及び表示態様から、現在における仮想オブジェクトの表示位置及び表示態様を決定できる。
