They needed to have the head detective shout “Enhance!” at the technician a few times to improve the image like they do on TV. I think it was on CSI they did that and got a perfect security camera picture of the perpetrator off a reflection from the victim’s eye. I calculated that it would have been six pixels wide even with a HD camera, so the boss would have needed to shout “Enhance!” at least twice more than he did. < /eyeroll>
That always annoys the alimentary canal waste product out of me.
The most ridiculous CSI example I can recall was when they enhanced a grainy image from an ATM security camera — the object was the windshield car registration sticker on a vehicle parked across the street — at night. They read the numbers on the decal.
