Abstract:
(EN) The present invention has multiple light-receiving sensors, multiple illumination light sources, a retroreflective plate, and a control device. The retroreflective plate is arranged at the periphery of a display surface, and the multiple illumination light sources radiate light toward the retroreflective plate. The multiple light-receiving sensors receive light reflected by the retroreflective plate and light radiated from an electronic pen (light-emitting body). The control device controls the multiple illumination light sources and a light-emitting unit of the electronic pen, and sets the time ratio and the timing for a non-light-emitting body detection mode and a light-emitting body detection mode on the basis of a past detection condition for an operator's finger (non-light-emitting body) and the electronic pen.
(FR) La présente invention possède de multiples capteurs de réception de lumière, de multiples sources de lumière d'éclairage, une plaque rétro-réfléchissante et un dispositif de commande. La plaque rétro-réfléchissante est agencée à la périphérie d'une surface d'affichage et les multiples sources de lumière d'éclairage émettent une lumière vers la plaque rétro-réfléchissante. Les multiples capteurs de réception de lumière reçoivent la lumière réfléchie par la plaque rétro-réfléchissante et la lumière émise par un stylo électronique (un corps électroluminescent). Le dispositif de commande commande les multiples sources de lumière d'éclairage et une unité électroluminescente du stylo électronique et règle le rapport temporel et le moment pour un mode de détection de corps non électroluminescent et un mode de détection de corps électroluminescent sur la base d'une condition de détection antérieure d'un doigt d'un opérateur (un corps non électroluminescent) et du stylo électronique.
(JA) 複数の受光センサ、複数の照明光源、再帰反射板、制御装置などを有している。再帰反射板は表示面の周囲に配置され、複数の照明光源は、再帰反射板に向けて光を射出する。複数の受光センサは、再帰反射板で反射された光、及び電子ペン(発光体)から射出された光を受光する。制御装置は、複数の照明光源、電子ペンの発光部を制御するとともに、操作者の指(非発光体)及び電子ペンの過去の検出状況に基づいて、非発光体検出モードと発光体検出モードの時間比率及びタイミングを設定する。
