Figure 10. Pulse width control CCIR.
Note: • Do not input external VD signal at Pin No. 7 of the 12-pin Hirose connector, as it may disturb the
external trigger function.
3.2.3 Integrate Mode
The standard factory setting for the RM-67X camera is FRAME MODE.
In addition to the External Trigger modes, there is an External Integrate mode on pin 12 on the 15 pin connector. This
allows frames to continually integrate until this input pin is released.
To use this mode:
Input: Ext. trigger to pin 12 on 15 pin connector.
Set MFI mode: “VD mode”
Set MFI Termination: “Hi Z”
Set Trigger mode: “Off”
Set Vertical mode: “Field” or “Frame”
3.2.4 Vertical Mode
The standard factory setting for the RM-67X camera is FRAME MODE.
In Field Mode, two horizontal rows are scanned together, changing the pair at each interlace scan. The sensitivity of the
CCD is doubled for one field of integration, therefore it can obtain the same sensitivity as in Frame Mode in half the period
of time. This is an advantage when the shutter is used often. Because of the alternating two-row scanning, Moire is almost
unnoticeable. While the vertical resolution is not as good as in Frame Mode, it is sufficient to view the full vertical
resolution of the TV format. Note: Only odd fields are output in this mode. Field Mode cannot provide full frame resolution
with strobe lighting applications
