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.
