Abstract
An apparatus is described that includes first and second pixels arrays integrated on a same semiconductor chip. The first pixel array contains visible light pixels and no Z pixels. The second pixel array contains Z pixels and no visible light pixels. The first and second pixel arrays do not overlap on said same semiconductor chip.
Claims21
(canceled)
A device comprising:
- a visible light optical system that is configured to pass visible light and to block infrared light, and a separate, infrared light optical system that is configured to pass infrared light and block visible light;
- and
- an image sensor that includes a visible light pixel array for receiving visible light that passes through the visible light optical system, and an infrared light pixel array for receiving infrared light that passes through the separate, infrared light optical system, wherein the visible light pixel array and the infrared light pixel array are both mounted on a same semiconductor chip.
A system comprising:
- a camera comprising:
- a visible light optical system that is configured to pass visible light and to block infrared light, and a separate, infrared light optical system that is configured to pass infrared light and block visible light;
- and
- an image sensor that includes a visible light pixel array for receiving visible light that passes through the visible light optical system, and an infrared light pixel array for receiving infrared light that passes through the separate, infrared light optical system, wherein the visible light pixel array and the infrared light pixel array are both mounted on a same semiconductor chip;
- and
- one or more computer processors that are configured to receive signals output by the image sensor, and to generate a pixelated depth profile of an object position in front of the camera.
3 more elements
A method comprising:
- passing visible light through a visible light optical system that is configured block infrared light;
- passing infrared light through a separate, infrared light optical system that is configured to block visible light;
- receiving, by an image sensor, the visible light at a visible light pixel array for receiving visible light that passes through the visible light optical system, and an infrared light pixel array for receiving infrared light that passes through the separate, infrared light optical system, wherein the visible light pixel array and the infrared light pixel array are both mounted on a same semiconductor chip.
