CAMELIA 8M Digital Camera

1986B–IMAGE–03/03

R.O.I (REGIONS OF

INTEREST)

Caution: This function is available only since the 5th October 2001 with the Camera S/N:

01321093. For older Cameras, these commands aren’t available and can corrupt the

EEPROM (see “Camera Identification” on page 13).

CAMELIA 8M (both Color and Black & White) can operate in a “multi ROI” mode allow-

ing masking of regions of the image and thus increasing frame rate by a reduced

readout time.

User defines up to 5 windows to be masked. In addition he specifies starting and ending

addresses for each window.

Time reduction: about 92 µsec per masked line.

Two steps (under RS232 controls or Commcam):

• Enter the list of starting and ending addresses by the command:

Y=ssss/eeee/ssss/eeee/…/eeee/

• Enter the number of regions masked by the command: F=X (X=0 to 5)

Rules The line addresses must be a multiple of 4 (to be compliant with the binning).

The Image starts at Line 0 and ends at Line 3499 and the smallest area is of 4 lines.

The commands must be send in the following order: “Y=…” then “F=…”.

For FGT Software Users, the user has to resize the number of lines in FGT settings.

Example In order to mask 3 regions in the “wafer image” defined as following:

• The First 304 lines at the top of the image (blue background)

• 748 lines in the center of the image (two center lines of the wafer)

• The last 304 lines of the image (blue background):

– "Y=0/304/1376/2124/3196/3499/"

–"F=3"

In this example readout time will be reduced of 1356 lines equivalent to 125 ms.
