Abstract
(EN)
Disclosed are a method for correcting handwriting data and an apparatus therefor, the method comprising: emitting laser light toward a surface; detecting speckle patterns on the basis of the emitted laser light to convert the speckle patterns into image signals; detecting a moving direction and a moving distance of a pen tip by comparing the speckle patterns of the image signals; correcting the detected moving direction and moving distance of the pen tip by using an detected inclination direction and angle of an electronic pen; when a pen pressure detection signal is received, transmitting the corrected moving direction and moving distance of the pen tip to the outside.
(FR)
L'invention concerne un procédé de correction de données d'écriture manuscrite et un appareil associé, le procédé consistant : à émettre une lumière laser vers une surface ; à détecter des motifs de granularité sur la base de la lumière laser émise pour convertir les motifs de granularité en signaux d'image ; à détecter une direction de déplacement et une distance de déplacement d'une pointe de stylo par comparaison des motifs de granularité des signaux d'image ; à corriger la direction de déplacement détectée et la distance de déplacement de la pointe du stylo à l'aide d'une direction d'inclinaison détectée et d'un angle d'un stylo électronique ; lorsqu'un signal de détection de pression du stylo est reçu, à transmettre la direction de déplacement corrigée et la distance de déplacement de la pointe du stylo à l'extérieur.

표면을 향하여 레이저광을 조사하고, 조사된 레이저광에 기초한 스펙클 패턴을 검지하여 영상 신호로 변환하고, 영상 신호의 스펙클 패턴을 비교하여 펜팁의 이동 방향 및 이동 거리를 검출하고, 감지된 전자펜의 경사 방향 및 각도를 이용하여, 검출된 펜팁의 이동 방향 및 이동 거리를 보정하고, 필압 감지 신호를 수신하는 경우, 보정된 펜팁의 이동 방향 및 이동 거리를 외부로 송신하는 필기 데이터 보정 방법 및 그 장치가 개시되어 있다.
