Everything about The Panoscan totally explained
The
Panoscan is a high resolution digital
panoramic camera. The first Panoscan model MK-1 cameras were manufactured and sold starting in January 1999 by Panoscan Inc. in
Los Angeles, California. The subsequent MK-2 and MK-3 models improve on resolution and speed over the MK-1 model.
The Panoscan camera uses a tri-linear
CCD array in much the same way as a slit film rotational camera might operate. The camera assembles an image by capturing a single line of pixels at a time while rotating through a 400 degree arc. The digital images from a
rotating line camera are extraordinarily sharp. With resolution capability up to 9,000 by 65,000 pixels, images can be printed at 30 feet (10
metres) in length while maintaining extreme sharpness.
The MK-3 Panoscan camera accepts
medium format lenses from 22.5 mm up to 300 mm focal lengths. Unlike film-based rotational cameras, the digital Panoscan camera can be used with a special 22.5 mm
fisheye lens to capture completely spherical images for use in computer-based virtual reality players such as
QuickTime VR. Due to the dimensional stability of the digital images they can be used for various measurement purposes such as
Photogrammetry. The Panoscan company also offers a photogrammetry application for measuring the panoramic images called PanoMetric.
The Panoscan MK-3 camera is also capable of capturing extremely wide exposure range. While various types of
photographic film can capture anywhere from 6 to over 10
EV of
dynamic range, the Panoscan sensor can capture up to 12 EV in a single exposure. This extended range captures all of the highlight and shadow detail that would be missed on regular digital exposures. Furthermore, the digital image from the Panoscan can be combined into
high dynamic range images.
