3.5.2 Analog and Digital Signal Processing Chain

Processing Chain Overview and Description

The follow ing diagram show s a simplified block diagram of the camera’s analog and
d igital p rocessing chain. The analog p rocessing chain begins w ith an analog gain
ad ju stm ent, follow ed  by an analog offset ad ju stm ent. These ad ju stm ents are ap p lied  to
the vid eo analog signal p rior to its d igitization by an A/ D converter.

The d igital p rocessing chain contains the FPN correction, the PRN U correction, the
backgrou nd su btract, and the d igital gain and offset. All of these elem ents are u ser
p rogram m able.

Notes:



FPN and PRN U correction is not available w hen op erating the cam era in Are a Mod e.
For d etails on how to sw itch cam era op eration m od es, refer to section 3.5.1 .



The follow ing u ser settings are stored  sep arately for forw ard  and  reverse d irection;
analog gain, analog offset, d igital gain, d igital offset, and  backgrou nd  su btract. They
are saved  u sing the

refer to section 3.3.3 Setting the Cam era’s CCD Shift Direction .

Analog Processing

Op tim izing offset p erform ance and  gain  in the analog d om ain allow s you  to achieve a
better signal-to-noise ratio and  d ynam ic range than you  w ou ld  achieve by trying to
op tim ize the offset in the d igital d om ain. As a resu lt, p erform  all analog ad ju stm ents p rior
to any d igital ad ju stm ents.
