STEP 2: Find Hot Pixel Coordinates
Click the hot pixel to find its X, Y coordinates.
The coordinates are 593, 2816 ― where X (Column) = 593 and Y (Row) = 2816.
IMPORTANT: Frame grabbers from different manufacturers may display pixel location
coordinates in different order, for example:
You must put defective pixel coordinates into the pixel correction map file in this order:
X (Column), Y (Row).
If your frame grabber identifies pixel coordinates by X (Row), Y (Column), you must transpose
the coordinates to X (Column), Y (Row) before entering them into the pixel map files. For
example, if the 593, 2816 coordinates in the screen above had been displayed in this order,
where X:593 is row and Y:2816 is column, you would have had to transpose the coordinates to
2816, 593.
STEP 3: Adjust Defective Pixel Coordinates
As described in STEP 1, if the first pixel coordinates are 0, 0, you must adjust the hot pixel
coordinates by adding 1 to both coordinates as shown in the following:
If the frame grabber pixel coordinates are Column (X), Row (Y), then go to STEP 4.
•
• If the frame grabber pixel coordinates are Row (X), Column (Y), then transpose the
coordinates to the form Column, Row and then go to STEP 4.

a. Click the pixel to display X, Y
coordinates below.
X (Column), Y (Row) or,
X (Row), Y (Column).
593 (+1), 2816 (+1) = 594, 2817
