Abstract

Un aspect de la présente invention concerne un dispositif d'endoscope à capsule. Le dispositif comprend : un premier système optique possédant un champ de vision (CV) plus large qu'une valeur de référence pour observer un site cible; un deuxième système optique pour agrandir et observer un site cible possédant une dimension de l'ordre du nanomètre (nm) au millimètre (mm); et une partie de transfert pour transmettre des données d'image acquises à partir d'au moins l'un parmi le premier système optique et le deuxième système optique à un récepteur.
