Processing Chain Overview and Description

The following d iagram shows a simp lified  block d iagram of the camera’s analog and  d igital processing
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 i gitization 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 and  m ost are m em bers of the
