Rapid Synchronized Lighting and Shuttering

摘要

This document describes various apparatuses and techniques for rapid synchronized lighting and shuttering. These apparatuses and techniques are capable of capturing two images, where one of the images integrates multiple exposures during which an image area is illuminated by a light source and another of the images integrates multiple exposures during which the image is not illuminated by the light source. The image area can be illuminated by rapidly flashing the image area with the light source and synchronizing a shutter to permit one image sensor to capture an image when the image area is illuminated and another image sensor to capture the image area when the image area is not illuminated. These two images can be captured concurrently or nearly concurrently, thereby reducing or eliminating motion artifacts. Further, these apparatuses and techniques may do so with slow and relatively low-cost cameras and relatively low computational costs.

主权项

1. A controller configured to:
synchronize flashing of a light source and shuttering of a shutter effective to enable capture of a first image integrating multiple exposures during which the light source is flashed and a second image integrating multiple exposures during which the light source is not flashed; and provide the first image and the second image, the first image and the second image usable to determine a net image in which one or more additional light sources other than the light source are excluded.
