Title
(EN) INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE TRAITEMENT D'INFORMATIONS
(JA) 情報処理装置、情報処理方法
Abstract
(EN) An information processing device according to the present invention is provided with: a position detection unit that detects, on the basis of a captured image of an input surface, a light spot formed on the input surface with light emitted from an input device having a light-emitting part, and that detects a prescribed representative position in the light spot as a provisional input position, which is a provisional position of an input position; a tilt estimation unit that estimates the tilt status of the input device with respect to the input surface on the basis of orientation-change synchronous information, which changes in synchronization with orientation changes of the input device; and a correction unit that corrects the provisional input position on the basis of the tilt status of the input device as estimated by the tilt estimation unit.
(FR) Un dispositif de traitement d'informations selon la présente invention comprend : une unité de détection de position qui détecte, sur la base d'une image capturée d'une surface d'entrée, un point lumineux formé sur la surface d'entrée, de la lumière étant émise depuis un dispositif d'entrée ayant une partie électroluminescente, et qui détecte une position représentative prescrite dans le point lumineux comme position d'entrée provisoire, qui est une position provisoire d'une position d'entrée; une unité d'estimation d'inclinaison qui estime l'état d'inclinaison du dispositif d'entrée par rapport à la surface d'entrée sur la base d'informations synchrones de changement d'orientation, qui changent en synchronisation avec des changements d'orientation du dispositif d'entrée; et une unité de correction qui corrige la position d'entrée provisoire sur la base de l'état d'inclinaison du dispositif d'entrée tel qu'estimé par l'unité d'estimation d'inclinaison.
(JA) 本技術に係る情報処理装置は、発光部を有する入力装置が発した光によって入力面に形成される光スポットを入力面の撮像画像に基づき検出し、光スポット内における所定の代表位置を入力位置の暫定位置である暫定入力位置として検出する位置検出部と、入力装置の姿勢変化に連動して変化する姿勢変化連動情報に基づき、入力面に対する入力装置の傾き状態を推定する傾き推定部と、傾き推定部が推定した入力装置の傾き状態に基づいて、暫定入力位置を補正する補正部とを備える。
