IR MENU
The IR menu (infrared) provides status information and controls for the IR sensor. Operators can use this menu to
calibrate the IR camera’s focal plane array (similar function to film or digital CCD) by selecting one of 2 options:
•
1-Point – A scene based thermal profile
•
2-Point – Both a scene based and a built-in infrared source thermal profiles
Operators can also access a Level 3 Miscellaneous sub menu for additional diagnostic information in the form of
sensor component temperatures.

Description
VALUE FIELDS
TEMPORAL PROC
LOW, MEDIUM,
HIGH, OFF
Enables or disables temporal processing which can be used to remove pixel
flicker or variations from the image.
SPATIAL PROC
ON, OFF
Enables or disables spatial processing which can be used to improve image
sharpness and improve edge detection.
EZOOM
1x, 2x and 4x
Sets the degree of electronic zoom:
• At 1x zoom, the video’s field of view = the optical field of view.
• At 2x zoom, the video’s field of view = ½ of optical field of view.
• At 4x zoom, the video’s field of view = ¼ of optical field of view.
Note: The 4x option is only available on some IR sensors and not available on
the VNFOV.
CALIBRATION
1 POINT
Selects a 1-Point calibration option to remove of common video artifacts and
reset dynamic range of the thermal image. This is the quickest calibration and
most recommended option for operator use.
2 POINT
Selects a 2-Point calibration option to remove bright video artifacts, recalculates
pixel uniformity measures and resets dynamic range of thermal image. This is
the longest calibration and not recommended for operator use. Use only when a
1-Point calibration does not yield satisfactory results.
