An image capturing apparatus including a plurality of image sensing modules and at least a light source is provided for image capturing an eye. Each of the image sensing modules includes an image sensor and a lens. The light source emits an illumination light, and the illumination light irradiates the eye. The eye reflects the illumination light into an image light. The image light includes a plurality of image sub-beams, and the image sub-beams are transmitted to the image sensors of the image sensing modules through the lenses of the image sensing modules, respectively. A detecting method is also provided.一種影像擷取裝置,包括多個影像感測模組以及至少一光源,用以擷取一眼球之影像。每一影像感測模組包括一影像感測器及一鏡頭。光源發出一照明光,照明光照射於眼球。眼球將照明光反射成一影像光。影像光包括多個子影像光束,這些子影像光束分別經由這些影像感測模組的這些鏡頭而傳遞至這些影像感測器。一種擷取方法亦被提出。10‧‧‧影像擷取裝置20‧‧‧眼球100‧‧‧影像感測模組200‧‧‧光源110‧‧‧影像感測器120‧‧‧鏡頭101、102、103‧‧‧影像感測模組L‧‧‧照明光B‧‧‧影像光BS、B1、B2、B3‧‧‧子影像光束F‧‧‧眼底X、X1、X2、X3‧‧‧光軸P‧‧‧瞳孔F1、F2、F3‧‧‧眼底區域130‧‧‧致動器140、141、142、143‧‧‧微處理單元150‧‧‧處理單元
