Abstract

La présente invention porte sur un bloc-notes professionnel adapté à l'électronisation et sur un procédé destiné à inclure ce bloc-notes dans un agenda électronique. Ledit procédé consiste : à capturer une image de page papier du bloc-notes professionnel adapté à l'électronisation; à déterminer le type de page papier en fonction de l'image de page papier, afin d'obtenir la position, sur la page papier, d'une zone de date imprimée sur la page papier du bloc-notes professionnel; à déterminer, au moyen d'un procédé de détection de lignes droites dans l'image, quatre lignes de bordure de l'image de page papier, à corriger la zone de page délimitée par ces quatre lignes de bordure pour créer une zone carrée, et à déterminer la position précise de la zone de date dans ladite zone carrée; à identifier une date et une heure dans la zone de date, à ouvrir automatiquement un agenda électronique, à établir une liste de tâches à la date et à l'heure identifiées dans l'agenda électronique, et à utiliser le contenu de la zone carrée corrigée comme contenu de la liste de tâches. Dans la présente invention, un fichier électronique est ajouté automatiquement à l'agenda électronique au moyen d'un logiciel d'application tel que CamScanner, dans le but de servir de contenu d'une liste de tâches, ce qui est pratique pour les utilisateurs et leur évite d'avoir à effectuer une entrée manuelle.
