Binary processing (fixed/threshold value correction)
By setting THESHLD. ADJ (threshold adjustment function), the IV-C35M can cope with variations in
lighting.
Threshold correction value
Boundary processing
See "Setting window boundaries (enable/disable)."
Brightness level
Indicates color brightness level.
[C]
CCD (charge capture device)
A charge capture device (CCD) converts light into electric signals. It consists of a photoelectric
converter to convert light and store it as an electric charge signal, a scanner to read the stored
G
electric charges, and an output section to transmit the signals as a stream of data.
CCD trigger
The CCD trigger allows sampling a part of the CCD camera image at high speed. When the
sampled image changes, the camera starts the shutter operation to capture a new image. With this
built-in shutter operation, an external sensor, such as a photo sensor, is not needed to trigger the
shutter. A window can be created to trigger the shutter operation. The window can be set for each
item on the production line so that adjustments to the position of an external sensor are no longer
needed. This feature reduces the down time needed to change object types on production lines.

Feed
direction
Center of gravity
The "center of gravity" is the geographical center of the image. It is determined by treating the binary
image to be measured as an object that has mass.
C mount
A system for mounting lenses on a camera body. The flange back (the distance from the reference
level for mounting a lens to the focal plane surface) is defined as 17.526 mm.
Fails to convert the image
due to a variation in lighting

Window for triggering the shutter operation
(threshold adjustment function), the
monitor brightness functions must be
selected to measure variations in lighting.
If you don't select the monitor brightness
