Image Corrections
Descriptions
Bad Pixel Correction
Enables static or dynamic pixel corrections. You can enable static
and dynamic pixel correction independently or simultaneously. You
can adjust the intensity threshold for the hot pixel or defective
corrections using the Threshold slider (0
–
4095).
•
Off:
disables Bad Pixel Correction.
•
Factory:
corrects bad pixels identified with predetermined and
preloaded defective and hot pixel maps created by the factory.
•
Dynamic:
pixel correction works independently of defective or
hot pixel maps. The camera determines which pixels need
correction based on a threshold value you create and performs
the correction automatically.
•
Dynamic&Factory:
Combines dynamic pixel correction and use
of factory bad pixel maps.
•
User:
Corrects bad pixels identified by user-created correction
maps.
•
Dynamic&User:
Combines dynamic pixel correction and use of
factory bad pixel maps.
Correction Depth
For Dynamic Pixel Correction, you can set a threshold level from 0
to 4095 for 12-bit images. The camera will correct all hot pixels
having an amplitude (hot pixel intensity minus average pixel
intensity) higher than the threshold setting.
FFC
Activates a flat field correction table created by the factory or user.
The Flat Field Correction mechanism corrects for variation in
illumination caused by the lens over the field of the array. You can
turn FFC off or select from one of two FFC tables, FFC #1 and FFC #2.
FFC is not available for small format image sensors.
LUT
Activates a Lookup Table for modifying and transforming the
original video data into any arbitrary value. The camera supports
four lookup tables. LUT#1 is pre-loaded with standard Gamma 0.45.
Negative Image
Reverses the image
(2’s complement)
so that the lightest areas
appear darkest and the darkest areas appear lightest.
3.9.9 Test
Use the test function on the Image Parameters panel to check camera communications
and to generate test images.
