Panasonic WV-CP410

NEW FUNCTIONS
1. ELC (Electronic Light Control)
in this mode a continuously variable electronic shutter
is employed to automatically control exposure times in
the CCD Image Sensor, according to the incoming
light level. When this mode is selected, a fixed or man-
ual iris lens can be used instead of an ALC type lens.
1.
Under bright conditions, such as outdoors, use an
ALC type lens as the ELC control range is not wide
enough under these conditions.
. Under certain unique lighting conditions, the fol-
lowing may appear;
¢ strong smear and/or blooming on high light
objects such as spot lights or windows.
* noticeable flicker in the picture and/or colour
rendition variations.
* periodic variance of white balance
Should these phenomena occur, use an ALC lens.
. When using this camera in the ELC mode with a
fixed iris lens, the depth of field of the image may
be less than that obtained by using an ALC lens.
Depth of field varies inversely with the iris opening.
Thus, using this camera in the ELC mode with the
‘lens iris fixed fully opened will result in less depth

of field than if an ALC lens was used. (And distant
objects in the picture might not be in focus.)

OFF
When strong, unwanted background lighting interferes
with the clarity of important centre-of-scene objects,
turn this switch to the “ON” position.
Cautions :
1,
It is recommended io set this switch to the “BLC
OFF” position when using this camera with a
pan/tilt head or if the scene object haves a rapid
change in illumination, since the speed of lens iris
becomes slow in the “BLC ON” position.
. If the desired objects are not in the centre of the
picture, backlight compensation may not work
effectively.
