Claim 9:
10. The tracking controller of claim 8,
wherein the first and second sensing matrices correspond to a visible light sensing matrix and an infrared (IR) sensing matrix of an RGB-IR sensor,
wherein the imbalanced pixel sensing values are generated by the RGB-IR sensor in response to illumination from environmental lighting, the environmental lighting having a lower level in an IR band than at least one visible band, and
wherein the balanced pixel sensing values are generated by the RGB-IR sensor in response to illumination from the pre-determined light source in combination with the environmental lighting, the IR band of the pre-determined light source and the at least one visible band of the environmental lighting having substantially same levels.
