I don’t really understand how the camera could work well when you have a row of light emitters placed right in front of a row of light sensors. Seems like any microabrasion or dust or smudge of grease on the area of the lens will cause significant aberration, unless they simply cut off the leds in the area around the lens while in use. It should have a similar effect to trying to take a picture of snow falling at night with a flash: all you see is the brightly illuminated noise up front
