Light funnel mode (SNC-DM110 / DM160 /
CM120 only)
Light funnel increases the image sensitivity by
combining the charge from adjacent pixels in a CCD. In
this camera, one pixel is produced by a combined charge
equivalent to 2 × 2 pixels on the 1280 × 960 image. This
effect results in a low resolution but the high sensitivity.
The mode combining a summed charge is “Light funnel
on”, and the mode without combined charge is “Light
funnel off”.
Notes
• Light funnel does not work when the followings are
set:
– The image size is JPEG - 960 × 720 : MPEG4 -
OFF or JPEG - 768 × 576 : MPEG4 - OFF.
– JPEG cropping is On.
– SolidPTZ is On.
– Iris open is On.
• You may feel the image resolution is reduced when the
Light funnel is On.
• The image file may not be created correctly during
switching the Light funnel modes.
