I have a sensor device that give me raw data for an image of 1201 by 861 pixels at 16 bits per pixel.

Although monochromatic, I would like to represent it in an RGB bitmap. I use an NSInteger [3] to populate the pixels via setPixel.

You should really consider using the vImage framework (part of the Accelerate framework) to perform this transformation. It is almost certain to be faster than what you're doing and less prone to errors.
