Abstract

La présente invention concerne un terminal mobile pour la détection de la glycémie comprenant un processeur (1001) et une caméra proche infrarouge (1002). La caméra proche infrarouge (1002) obtient des premières informations d'image d'une personne sur laquelle la détection est réalisée. Le processeur (1001) obtient une première valeur de glycémie correspondant aux premières informations d'image selon une équation prédéfinie, compare la première valeur de glycémie avec une plage de sécurité de glycémie prédéfinie pour obtenir le premier résultat de comparaison, et détermine si la valeur de glycémie de la personne sur laquelle la détection est réalisée est anormale selon le premier résultat de comparaison. La détection de la valeur de glycémie à l'aide du terminal mobile équipé de la caméra proche infrarouge est pratique.
