Well, the European Space Agency has built a 1 gigapixel (a gigapixel is 1024 megapixels) digital camera for its upcoming Gaia space telescope, due for launch in 2010...not 2.5.....
This is as they say on the site...."produced", not "taken"...
Below are some facts and figures about the gigapixel image:
Final image dimensions: 78.797 x 31.565 pixels
Number of pixels in final image: 2,487,227,305 (2.5 gigapixel)
Final image file format: 24-bit colour bitmap
Final image file size: 7.5 GBytes
Number of source images: 600
Number of pixels in source images: 3,537,408,000 (600 images * 3008*1960)
Lens focal length: 400 mm (equivalent to 600 mm on a 35 mm camera)
Aperture: F22, Shutter speed: 1/100, ISO: 125
Horizontal field of view of final image: 93 degrees
Time required to capture component images: 1 hour and 12 minutes
Time required to match overlapping images: 20 hours
Time required to optimise project: 4 hours
Time required to compose the image: 3 full days using 5 high-end pcs
Time required to blend seams / correct misalignments / finalise image: 2 days |
Oh I see, it's a composite image. Can you imagine the size of the lense you would need to have an optical resolution that high?!??!?!?
Let's just say you'd need a good-sized crane to move it around.  |
