Claim Text:
1. A depth-sensing camera system, comprising: a common sensor configured to record color and infrared data from target; an infrared illuminant that projects infrared light on the target; a control logic that switches a mode of operation of the camera between a color mode and an infrared mode, wherein when in the infrared mode, the infrared illuminant operates to project the infrared light on the target and when in the color mode, the infrared illuminant is disabled; a color buffer for storing color chroma and luma values; a depth buffer for storing infrared luma data; an exposure/gain module that records frame rate and gain settings when the camera operates in the color mode; and computation module that corrects the color luma values according to the frame rate and gain settings and subtracts the color luma values from the infrared luma values to produce depth data.
