Exposure Modes in Detail
Mode 2: Internally Programmable Line Rate and Exposure Time (Factory Setting)
Mode 2 operates at a maximum line rate and exposure time.
•
When setting the line rate (using the
27H
ssf
command), exposure time will be reduced,
if necessary, to accommodate the new line rate. The exposure time will always be set
to the maximum time (line period – line transfer time – pixel reset time) for that line
rate when a new line rate requiring reduced exposure time is entered.
•
When setting the exposure time (using the
28H
set
command), line time will be
increased, if necessary, to accommodate the exposure time. Under this condition, the
line time will equal the exposure time + line transfer time.
