Claim 0:
1. An apparatus comprising:
a structured light projector configured to toggle a structured light pattern in response to a timing signal;
an image sensor configured to generate pixel data; and
a processor configured to (i) process said pixel data arranged as video frames, (ii) extract (a) IR images with said structured light pattern, (b) IR images without said structured light pattern and (c) RGB images from said video frames, (iii) generate a sensor control signal in response to said IR images with said structured light pattern and said RGB images, (iv) calculate an IR interference measurement in response to said IR images without said structured light pattern and said RGB images and (v) select a mode of operation for an IR channel control and an RGB/IR channel control in response to said IR interference measurement, wherein
(a) said sensor control signal is configured to adjust an exposure for said image sensor for both said IR images with said structured light pattern and said RGB images,
(b) said IR channel control is configured to adjust said exposure for said IR images with said structured light pattern, and
(c) said RGB/IR channel control is configured to adjust said exposure for said RGB images and said IR images without said structured light pattern.
