Exposure Time (Shutter) And Offset; Exposure Time Offset - AVT Pike Technical Manual

Controlling image capture

Exposure time (shutter) and offset

The advanced register allows start of the integration to be delayed by max.
21
2 µs, which is max. 2.1 s after a trigger edge was detected.
Note
• Switching trigger delay to ON also switches external
Trigger_Mode_0 to ON.
• This feature works with external Trigger_Mode_0 only.
The exposure (shutter) time for continuous mode and Trigger_Mode_0 is
based on the following formula:
Shutter register value x time base + offset
The register value is the value set in the corresponding IIDC 1.31 register
(SHUTTER [81Ch]). This number is in the range between 1 and 4095.
The shutter register value is multiplied by the time base register value (see
Table 128: Time base ID
A camera-specific offset is also added to this value. It is different for the
camera models:

Pike F-145-15fps
