Glossary
Pixel
On the CCD, the electrically charged elements are in close proximity, arranged in a matrix (480 lines
in vertical direction, 512 rows in horizontal direction). One element is equivalent to one pixel.
Progressive scan
See "Full pixel reading."
[R]
Random shutter function
This function allows the CCD camera shutter operation to be triggered when even an object to be
measured reaches a specified position in the camera's field of view.
In order to make a partial reading of the CCD image at high speed, the IV-C35M is equipped with
the detection function described above with the works just like a proximity sensor to trigger the CCD.
A proximity sensor can also be connected to the system.
Resolution
The CCD in the IV-C35M contains 512 pixels horizontally and 480 pixels vertically. If it takes a full
picture, the resolution will be X/512 and Y/480.
[S]
Saturation (chroma)
Indicates color vividness level.
Search area
A portion of the target image to be compared with the reference image, using the gray scale search
function.
G
Search pixel
The relationship between detection precision and search speed, and also between pixel contraction
(reduce the number of pixels in the image that must be searched) and search speed, is shown
below:
- DETECTION PRECISION: High speed + [STANDARD-HIGH] _ Low speed
- PIXEL CONTRACTION:
Setting window boundaries (enable/disable)
This function enables and disables the labeling (object identification) of binary images located that
cross over the window frame boundary.
