PixelPro 3.2 Instruction Manual
Contrast: Higher contrast yields a clearer picture with brighter colors. Setting ranges
from 0 to 63.
Sharpness: Improves clarity of picture edges.
DPC: Reduces image bad points. Ranges from 0 to 3. 3 is default for FL-20.
Black level: Adjusts gray value of dark field backgrounds. Ranges from 0 to 255. Default
value is 12, for Monochrome Cooling camera only.
3D noise reduction: Takes the average from adjacent frames of a picture and
automatically filters out non-overlapping information, so as to obtain a cleaner and
clearer picture. The number of frames can be customized. Ranges from 0 to 5 for Fl-20.
Defaults to 3.
Flat Field Calibration: In current microscope applications, images captured by the
camera may be uneven or show color patches, due to problems in microscope light
sources, optical path systems, or dirty spots on the microscope eyepieces and objectives.
With flat field calibration, those types of defects can be effectively reduced, imaging
effects will be more uniform, and color reproduction of the images is smoother and more
realistic.
Operations:
1) Click [Flat Field Calibration Wizard]. Move the viewing field of the camera to a blank
background, as shown in the right figure (1). Click [Next].
2) Move the first background to a new blank background. Click [OK] to apply the Flat
Field Calibration function, as shown in the right figure (2).
3) Click [ ] to uncheck and exit the flat field correction mode. Check the box to re-
apply flat field corrections without repeating the wizard procedure.
Notes:
1) Flat Field Calibration requires manually setting the exposure time, such that the
image is not too bright or too dark, and all the pixel values are within the range of
64DN to 254DN.
2) The brightness of the two reference backgrounds for calibration should be almost
the same except for some variable spots. These two backgrounds should not be
"significantly inconsistent."
