Abstract

L'invention concerne un dispositif d'aide à la lecture d'image (3) qui comprend une unité principale (41), un élément transparent (32), une partie de maintien de document (61) et une partie de maintien de dispositif de lecture (42). Dans l'unité principale (41) est formée une surface de placement de document (45) sur laquelle est placée une feuille souhaitée (74) d'un livret (71). L'élément transparent (32) fait face à la surface de placement de document (45). La partie de maintien de document (61) maintient une partie du livret (71) différente de la feuille souhaitée (74) lorsque la feuille souhaitée (74) est placée sur la surface de placement de document (45). La partie de maintien de dispositif de lecture (42) maintient un dispositif de lecture (2). Lorsque la feuille souhaitée (74) est placée sur la surface de placement de document (45), le dispositif de lecture (2) utilise la lumière traversant l'élément transparent (32) et capture une image de la surface de lecture de la feuille souhaitée (74) faisant face à l'élément transparent (32).
