Rapid synchronized lighting and shuttering
First Claim
1. A system comprising:
- a controller configured to;
synchronize flashing of a first light source and a second light source and shuttering of a shutter effective to capture a first image integrating multiple exposures during which the first light source is flashed and a second image integrating multiple exposures during which the second light source is flashed; and
provide the first image and the second image, the first image and the second image are processed to determine a position or location of an object captured in the first image and the second image.

Abstract
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.

12. A method comprising:
-
rapidly flashing an object with a first light source and a second light source; synchronizing shuttering of a first shutter to the rapid flashing of the first light source effective to enable capture a first image integrating multiple exposures; synchronizing shuttering of a second shutter to the rapid flashing of the second light source effective to enable capture of a second image integrating multiple exposures; comparing the first image and the second image effective to determine a position or location of an object captured in the first image and the second image. - View Dependent Claims (13, 14, 15, 16)

17. A computing device comprising:
-
a first light source configured to flash at a first flash rate; a second light source configured to flash at a second flash rate; a first mechanical shutter configured to shutter at least as fast as the first flash rate; a second mechanical shutter configured to shutter at least as fast as the second flash rate; a controller configured to; synchronize flashing of the first light source and shuttering of the first shutter effective to capture a first image integrating multiple exposures during which the first light source is flashed and synchronizing flashing of the second light source and shuttering of the second shutter effective to enable capture of a second image integrating multiple exposures during which the second light source is flashed; and provide the first image and the second image, the first image and the second image are processed to determine a position or location of an object captured in the first image and the second image. - View Dependent Claims (18, 19, 20)
