Ë Progressive scan
- See "Full pixel reading."
Ë Resolution
The CCD in the IV-S30 contains 512 pixels horizontally and 480 pixels vertically. If it takes a full picture,
the resolution will be X/512 and Y/480.
[R]
Ë Random shutter function
This function allows the CCD camera shutter operation to be triggered when even an object to be mea-
sured 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-S30 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.
Ë 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:
[S]
Ë Search area
A portion of the target image to be compared with the reference image, using the gray scale search
function.
- DETECTION PRECISION: High speed + [STANDARD-HIGH] _ Low speed
- PIXEL CONTRACTION: High speed + [3 - 2 - 1] _ Low speed
Search speed
Ë 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.
