1. A dual-mode imager for imaging a scene illuminated by visible light, the dual-mode imager comprising:
- a light source configured to project onto the scene a structured illumination from which visible light is filterable;
a detector configured to capture both the structured illumination and visible light from the scene; and
a filter to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.

Abstract
A dual-mode includes a light source configured to project a structured illumination from which visible light can be filtered. The dual-mode imager also includes a detector configured to capture both the structured illumination and visible light from the scene. A temporal or spatial filter is used to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.

15. A dual-mode imager for imaging a scene, the dual-mode imager comprising:
-
a near-infrared light source configured to project onto the scene a depth-imaging illumination having a near-infrared wavelength; a complementary metal-oxide-semiconductor configured to capture near-infrared light and visible light from the scene; and a rotating wheel filter optically intermediate the scene and the complementary metal-oxide-semiconductor, the rotating wheel filter including a first portion configured to block visible light and pass near-infrared light and a second portion configured to pass visible light. - View Dependent Claims (16, 17, 18, 19)

20. A method of constructing a color image and a depth image, the method comprising:
-
projecting onto a scene a structured illumination having a near-infrared wavelength; temporally alternating between blocking visible light from the scene to a detector and passing visible light from the scene to the detector; while blocking visible light from the scene, capturing the structured illumination with the detector; while passing visible light from the scene, capturing visible light with the detector; generating the depth image based on the structured illumination captured with the detector; and generating the color image based on visible light captured with the detector.
