An image capturing module of a skin analysis device is provided, including a housing, a transparent element, an image sensing unit, an annular substrate, a plurality of light sources, and an annular optical mechanism. The transparent element is disposed at an end of the housing, and the image sensing unit is disposed in the housing and situated at a central axis of the image capturing module. The annular substrate is disposed in the housing, and the light sources are disposed on the substrate and surrounding the central axis. The light sources are situated between the transparent element and the image sensing unit in a direction of the central axis, and the annular optical mechanism is disposed in the housing and guides the light emitted from the light sources to the transparent element.本發明提供一種皮膚分析裝置之影像擷取模組,包括一殼體、一透光元件、一影像感測單元、一環狀之基板、複數個光源以及一環狀之光學機構。前述透光元件設置於殼體之一端,前述影像感測單元設置於殼體內,且位於影像擷取模組之一中心軸上。前述環狀之基板設置於殼體內,前述光源則設置於基板上並且圍繞前述中心軸。前述光源於中心軸方向上的位置介於透光元件和影像感測單元之間,且環狀之光學機構設置於該殼體內,並導引前述光源所發出之光線至透光元件。100‧‧‧指紋辨識模組10‧‧‧殼體11‧‧‧開口20‧‧‧透光元件21‧‧‧接觸面22‧‧‧下表面30‧‧‧影像擷取模組31‧‧‧結合部32‧‧‧感測面40‧‧‧光源50‧‧‧光學機構51‧‧‧發光面A‧‧‧中心軸B‧‧‧底座B1‧‧‧開孔C‧‧‧承載件D‧‧‧距離H、h1、h2‧‧‧距離L‧‧‧光線S‧‧‧基板W1、W2‧‧‧寬度θ‧‧‧入射角
