3.6 PIXEL MAP COMMANDS
The defective pixel map identifies Focal Plane Array (FPA) pixels that are stuck high, stuck low,
flashing, or otherwise defective. Pixels identified in the map are replaced with a filtered average of
neighboring pixels.
The Thermal Imaging Module (TIM) includes a cursor function that facilitates identifying
defective pixels. When the cursor is enabled, a single FPA pixel is replaced with a cursor value.
The cursor position may be relocated within the FPA as desired. The cursor value may be either
maximum hot (a white pixel) or maximum cold (a black pixel). The cursor value may be switched
as desired to improve its visibility on the scene.
Most of the defective pixel map commands require parameters consisting of a row and column
index. Row index 0 is the upper row of the FPA. The row index must be less than height of the
FPA in pixels. If the row index is out of range, the command will result in an error message.
Column index 0 is the left-most column of the FPA. The column index must be less than the width
of the FPA. If the column index is out of range, the command will result in an error message.
The commands in this section modify the active defective pixel map in DDR memory. None of
these commands modify the defective pixel map in non-volatile memory. If the modified pixel
map is to be used following a power cycle, the map must be burned to non-volatile flash with the
Flash Region Program From Active DDR Region (0xFB) command.
Camera RTL Rel version 01.00.0080 or newer is required together with compatible CPU(Rel)
version is required for all defective pixel map commands.
