History of digicamsThe digital cams produced in the 20th century.Digicams have a CCD(charged couple
device)Its more important.Camera sensors lift up the camera resolution
and pixel clarity.It is also called as digital films.Latest technology –(??????)

GIGAPAN TECHThe commercially available GigaPan robotic
mounts turn most digital cameras into extremely high-resolution panoramic imagers. The robotic unit guides the user through setting up a panoramic scene, then automates the image acquisition process, precisely taking individual pictures across a grid. These images are downloaded to a personal computer where free software stitches, renders, and projects the images together into a single explorable super-image. These massive gigapixel-sized images are stored. (1474 MEGA PIXELS)
