Abstract: An image capturing device that consists of one or multiple light sources and a image capturing device for imaging of a human face. The device enhances topographic information by capturing a multitude of digital images of a face in a fixed orientation with varying light source positions and combining the images with a blending algorithm. There may be multiple light sources or one light source that is repositioned with each image capture such that light source positions are not coincident. The blending algorithm can be applied to any number of a set of images in a fixed orientation where only the light source direction is varied. The device may include a support device to maintain the human face in a fixed orientation during image capture.
