In turn, the converted digital signal is processed into various pieces of information by the image processing unit to generate scan information of the object through various steps. After the sensor reads the image information, the path is similar to that of a conventional scanner, but there is no need for a device for moving a light source used in any form in the existing scanner.

Abstract

La présente invention concerne un scanner dans lequel, au lieu d'une source de lumière et d'un dispositif qui déplace la source de lumière qui sont utilisés dans les scanners en général, un affichage transparent suffisamment transparent pour transmettre la lumière reflétée et un capteur ayant la même largeur que l'affichage transparent sont utilisés dans le scanner. Ainsi, lorsque l'affichage transparent et le capteur fonctionnent tous deux comme source de lumière et un dispositif qui déplace la source de lumière, aucun dispositif de déplacement de source de lumière n'est nécessaire, ce qui permet d'augmenter la vitesse de balayage et la stabilité et de réduire la taille du scanner.
