Spyder3 GigE User’s Manual PRELIMINARY

DALSA 03-032-10158-04

Digital Signal Processing

To optimize camera performance, digital signal processing should be completed after any
analog adjustments.

FPN Correction

Performing FPN Correction

Syntax:

Performs FPN correction and eliminates FPN noise by subtracting
away individual pixel dark current.

Syntax:

ccf

Notes:

•

Perform all analog and digital adjustments before
performing FPN correction.

•

Perform FPN correction before PRNU correction.

•

Refer to

282H

Calibrating the Camera to Remove Non-Uniformity

(Flat Field Correction)on page

283H

68 for a procedural overview

on performing flat field correction.

•

To save FPN coefficients after calibration, use the

85H

wfc

command. Refer to section

284H

A3.1 Saving and Restoring

PRNU and FPN Coefficients for details.

•

The QuickCam software that ships with the Spyder3 GigE
camera has a flat field correction wizard. For easy flat field
correction, use the wizard located on the Calibration tab.

•

Related Commands:

86H

ccp

87H

wfc

Example:

ccf

Setting a Pixel’s FPN Coefficient

Purpose:

Sets an individual pixel’s FPN coefficient.

Syntax

sfc x i

Syntax Elements:

The pixel number from

sensor pixel count

Coefficient value in a range from

2047

(12 bit LSB).

Example:

sfc 10 50
