4.5.2 Analog and Digital Signal Processing Chain
Processing Chain Overview and Description
The following diagram shows 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 Area Mod e.
