Abstract
A depth sensing system includes a sensor having first and second sensor pixels to receive light from a surface. The system also includes a filter to allow transmission of full spectrum light to the first sensor pixel and visible light to the second sensor pixel while preventing transmission of infrared light to the second sensor pixel. The system further includes a processor to analyze the full spectrum light and the visible light to determine a depth of the surface. The filter is disposed between the sensor and the surface.

A depth sensing system, comprising:
- a sensor having first and second sensor pixels to receive light from a surface;
- a filter to allow transmission of a first proportion of visible light and a second proportion of infrared light to the first sensor pixel and a third proportion of visible light and a fourth proportion of infrared light to the second sensor pixel,
- wherein the first proportion of visible and the second proportion of infrared light result in a first sensed value at the first sensor pixel,
- wherein the third proportion of visible and the fourth proportion of infrared light result in a second sensed value at the second sensor pixel;
- and
- a processor to analyze the first and second sensed values to determine a depth of the surface,
- wherein the filter is disposed between the sensor and the surface.
