Figure 9. Edge Pre-Select Ccir - JAI RM-670 User Manual

3.2.2.2
The falling edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by the pre-
defined shutter speed set by RS-232C. (see section 8.3.63)
The leading edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by the pre-
defined shutter speed set by RS-232C.
The resulting video is output as "odd field" for CCIR, and appears 9H (CCIR) after the leading edge of WEN.
To use this mode:
Input:
Figure 9.
Note: • The duration of the external trigger pulse must be greater than 1H. It is recommended to make this
longer, typically 9H.
3.2.2.3
The falling edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by duration
of the trigger pulse.
The exposure time range is 1.5H to 1000H (shortest and longest pulse duration).
The resulting video is output as "odd field" for CCIR and appears 9H (CCIR) after the leading edge of WEN.
To use this mode:
