Each TV line takes roughly 50 microseconds, each field about 8 ms and
each frame about 16 ms. Furthermore the two fields which make up a frame
may be interlaced. Given this, how does one interpret data taken with a
shutter speed of 1/1000 sec (1 ms)?
If one can judge by the product, the image is frozen on the CCD in a
millisecond. That's whey they call it a "shutter speed". Of course
it is transmitted in a thirtieth of a second (approximately), and it
is *always* interlaced in NTSC TV. Examination of the single frame,
however, will show the spokes of wheels as straight lines at 1/1000
shutter speed. That would not be the case if the particular millisecond
corresponding to the pixel being transmitted was the one of interest.
In that case the spokes would be curved and some might even be missing.
Since time resolution seems to be a problem, have you considered taking
the experiment outside? Drop a lead fishing weight from a third story
window and videotape it.
