Exposure Offset
The VC-5MC-M/C110H camera adds an
Exposure Offset
automatically to the exposure time
determined by the
Exposure Time
parameter or the width of the external trigger signal.
To acquire an image with the desired exposure time, you must compensate for the
Exposure
Offset
as follows.
1.
Subtract the
Exposure Offset
from the desired exposure time.
2.
Set the
Exposure Time
parameter with the resulting time or use the resulting time as the
high or low time for the external trigger signal.

Table 8-1 Exposure Offset
For example, if you want to set an exposure time to about 300
㎲
under setting
Short Exposure
Mode
to
Off
, set the
Exposure Time
parameter to 297.53
㎲
(300 – 2.47 = 297.53) or use 270
㎲
as the high or low time for the external trigger signal.
