STEP 2: Find Defective Pixel Coordinates
Click the defective pixel to find its X, Y coordinates.
The coordinates are 593, 4816, where X (Column) = 593 and Y (Row) = 4816.
IMPORTANT:
Frame grabbers from different manufacturers may display pixel location
coordinates in different order, for example:
X (Column), Y (Row)
or,
X (Row), Y (Column).
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, 4816 coordinates in the screen above had been displayed in this order,
where X:593 is a row and Y:4816 is a column, you would have had to transpose the coordinates
to 4816, 593.
STEP 3: Adjust Defective Pixel Coordinates
As described in
STEP 1
, if the first pixel coordinates are 0, 0, you must adjust the defective pixel
coordinates by adding 1 to both coordinates as shown in the following:
593 (+1), 4816 (+1) = 594, 4817
•
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
.
