QUESTION:
During the press conferences, the scientists keep refering to the images
from the lander as "frames". What size is one frame (pixels height and
width, field of view, and/or data size) and how many frames are included in
a "typical" image?

ANSWER from David Mittman on July 13, 1997:
The Imager for Mars Pathfinder (IMP) camera uses the term "frame" to denote
a single exposure of a CCD which is about 256 x 256 pixels in size. A frame
covers a 14.4 degree field of view. One stereo image would be two 256 x 256
frames. One full-color image would be three frames (through red, green, and
blue filters). A full-color stereo image would be six frames, etc. Thirteen
frames are necessary to fully document a site on the ground using all of the
filters available for ground observations. Additional filters are available
for solar observations.
