4.5.2 Analog and Digital Signal Processing Chain

Processing Chain Overview and Description
The follow ing d iagram show s a sim plified block d iagram of the cam era's analog and
d igital processing chain. The analog processing 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 applied to
the vid eo analog signal prior to its d igitization by an A/ D converter.
The d igital processing 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
program m able.
