Gigapixel question (cameras)?

Q. I know for example there could be a camera that has 14 megapixels. My first question is how do people measure a (mega)pixel? And I know there isn't a gigapixel, but would it be like SUPER high quality?


Answer
They measure it by knowing how many individual photosensitive elements there are on the camera sensor. If there are a million, then it's a megapixel.

There is a 1.8gigapixel camera, link

quoting

"The camera uses 368 five-megapixel camera sensors aimed through a telescopic array to pick out birds in flight and humans on the move on the Earthâs surface. ARGUS stands for Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System."

what is the highest amount of megapixels a camera can have?

thanx in advance!


Answer
Well, for now, the most anybody has obtained is in the GIGApixels. Yup, you heard me right. But, there is a catch, because these photos are stitched.

Ok so really, a camera that genuinely takes the greatest megapixel photos without any mumbo jumbo is the Dark Energy Camera, designed to take photos in space.

"The 500 megapixel Dark Energy Camera would be placed on an existing 4-meter telescope located in north-central Chile at the National Optical Astronomy Observatory's Cerro Tololo Inter-American Observatory. "

500 megapixel camera. Now thats something i'd like to see in a cell phone.
