3.4. Selecting Shutter Speed
The APX RS’s electronic shuttering system makes it possible to control the exposure
time within a frame regardless of the current frame rate. By using an exposure time that
is shorter than the frame time determined by the frame rate (i.e. 1/frame rate sec.), you
can capture events taking place at an extremely high speed as a still image without
blurring effect.
The shutter speed can be changed from the basic speed of 1/(frame rate) sec. up to
1/1,000,000 sec. (1 micro seconds
Note: See the Shutter Speed Reference table (subsection 6.1.8).
