An apparatus and a method for capturing a face image are provided. The apparatus and method determine a reflection on spectacles of a region around an eye within a face of a driver in real time and more stably and effectively reduce an influence of the reflection from the spectacles through an exposure control, without requiring an output for a difference image. In particular, an imaging device isoperated by performing an external exposure control to reduce the reflection on the spectacles in a vehicle to receive lighting on/off images and performing a difference image processing in an electronic control unit (ECU).
