An embodiment of the present invention provides an image processing and analyzing system, for ovulation detection, comprising an electronic apparatus, a saliva acquisition apparatus, an ovulation prediction apparatus and a control unit. The electronic apparatus comprises a camera part. The saliva acquisition apparatus has: a saliva accommodation part for accommodating the saliva of a subject； and a case having the saliva accommodation part disposed therein and having an outlet, through which the saliva accommodation part can be inserted and withdrawn, formed on one end and a through hole formed on one side such that the saliva is externally exposed. The ovulation prediction apparatus comprises: a body part having the electronic apparatus mounted on one side and an opening formed on the one side such that the camera part can be positioned on the opening； an insertion part formed on one side of the body part such that the saliva acquisition apparatus can be inserted at a fixed depth； and a light source part disposed inside the body part and for providing a light to the saliva acquisition apparatus. The control unit obtains a picked-up image of the saliva from the camera part, processes the obtained picked-up image and thus extracts a crystal structure image of a hormone comprised in the saliva, and determines for the ovulation of the subject on the basis of the extracted crystal structure image.Un mode de réalisation de la présente invention concerne un système de traitement et d'analyse d'image, pour la détection d'ovulation, comprenant un appareil électronique, un appareil d'acquisition de salive, un appareil de prédiction d'ovulation et une unité de commande.
