Abstract
Embodiments of an apparatus and process are described. The process includes capturing a first image frame using an image sensor, the image sensor including a pixel array comprising a plurality of pixels arranged in rows and columns and a color filter array optically coupled to the pixel array. A region of interest within the first image frame is determined, and the exposure time of the image sensor is adjusted to eliminate a substantial fraction of the visible light captured by the image sensor. A rolling shutter procedure is used with the pixel array to capture at least one subsequent frame using the adjusted exposure time, and a source of invisible radiation is activated while the rolling shutter enters the region of interest and deactivated when the rolling shutter exits the region of interest. Finally, an image of the region of interest is output. Other embodiments are disclosed and claimed.
