MOTOROLA
13.3 Offset Calibration Block
Offset adjustments for the MCM20027 are done in sep-
arate sections of the ASP to facilitate FPN removal and
final image black level set.
The
set the initial offset of the pixel output in a range that will
facilitate per-column offset data generation for varying
operational conditions. In most operational scenarios,

There are 64 registers that can be programmed with in-
dividual offset values. They will be applied to all the col-
umns on a single image frame on a Modular 64

Description
this register can be left in its default state of 00
a pre-image processing gain in comparison to the
bal DOVA Register
chain gain (pre A2D gain).
This register can also be used to apply a global offset
adjust. In this case, the user must take into account the
Color Gain and Global Gain registers to determine the
resulting offset at the output.
