3.7 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 digital 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 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. N on-linearity look-u p table (LUT) correction is available for the 4k m od el
of cam era.

All of these elem ents are u ser p rogram m able.
