Title (EN) ELECTRONIC BLACKBOARD AND CONTROL METHOD THEREOF
(FR) TABLEAU NOIR ÉLECTRONIQUE ET SON PROCÉDÉ DE COMMANDE
(KO) 전자칠판 및 그 제어방법
Abstract:
(EN) The present invention relates to an electronic blackboard including: a display unit; a first sensing unit which senses a touch position of cursive script on a screen of the display unit; a second sensing unit which captures and obtains images; and a processing unit which compares a series of images captured by the second sensing unit to determine a target region in which movement is present in the images, determines the color of the cursive script in the determined target region, and displays an image having the determined color at a position corresponding to the touch of the cursive script on the screen of the display unit. Accordingly, a user experience in which the user feels as though the user is directly writing on the electronic blackboard in the cursive script can be provided by automatically recognizing the color of the cursive script that touches the screen of the electronic blackboard, and displaying the trajectory of the cursive script in the color on the screen.
(FR) La présente invention concerne un tableau noir électronique comprenant : une unité d'affichage ; une première unité de détection qui détecte une position tactile d'un script cursif sur un écran de l'unité d'affichage ; une seconde unité de détection qui capture et obtient des images ; et une unité de traitement qui compare une série d'images capturées par la seconde unité de détection pour déterminer une région cible dans laquelle un mouvement est présent dans les images, détermine la couleur du script cursif dans la région cible déterminée et affiche une image ayant la couleur déterminée à une position correspondant au toucher du script cursif sur l'écran de l'unité d'affichage. Par conséquent, une expérience d'utilisateur dans laquelle l'utilisateur ressent comme s'il écrivait directement sur le tableau noir électronique dans le script cursif peut être fournie par reconnaissance automatique de la couleur du script cursif qui touche l'écran du tableau noir électronique et affichage de la trajectoire du script cursif dans la couleur sur l'écran.
(KO) 본 발명은 전자칠판에 관한 것으로서, 전자칠판은, 디스플레이부; 상기 디스플레이부의 화면에 대한 필기체(體)의 터치 위치를 감지하는 제1감지부; 촬상을 수행하여 이미지를 얻는 제2감지부; 및 상기 제2감지부에서 촬상한 일련의 이미지를 대비하여 상기 이미지 내에 움직임이 존재하는 대상영역을 결정하고, 상기 결정된 대상영역에서 상기 필기체의 색상을 결정하고, 상기 디스플레이부의 화면에서 상기 필기체의 터치에 대응하는 위치에, 상기 결정된 색상을 가지는 영상을 표시하는 처리부를 포함한다. 이에 의하여, 전자칠판의 화면을 터치하는 필기체의 색상을 자동으로 인식하여 그 색상으로 필기체의 궤적을 화면에 표시함으로써, 사용자가 해당 필기체로 전자칠판에 직접 필기를 하는 듯한 사용자 경험을 제공할 수 있다.
