5.3 Offset Calibration Block
Offset adjustments for the MCM20014 are done in sep-
arate sections of the ASP to facilitate FPN removal and
final image black level set.
The
Column DOVA DC Register; Table 17
, is used to
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,
this register can be left in its default state of 00
h
.
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.
The
Column DOVA Control Register; Table 18
, is used
to control the Column DOVA functionality and opera-
tional modes.
Setting bit
ece
enables the per-column DOVA to be
used and the per-column offset values loaded into the
DOVA RAM will be applied to the pixel output. The glo-
bal DOVA adjust circuit is enabled by default.
Setting the
cntr
bit resets the internal counter used to
repetitively load the RAM with user defined data. This is
used in cases where the system controller loses control
of the I
2
C bus while writing to the Column DOVA RAM.
Setting the
cal
bit configures the Column DOVA RAM
using internally generated offset data. When the
MCM20014 is first initiated, it will automatically gener-
ate and load the Column DOVA RAM with the appropri-
ate data. However, if operational conditions such as
temperature or operating frequency change, the user
can use the
cal
bit to re-determine the appropriate col-
umn data.
The automatic calibration data is calculated using the
average differential offset across four dark rows. This
feature does not create the most effective data for re-
ducing the column oriented fixed pattern noise of the
device. The user can calculate the column offset data
using their own algorithm and load this data via the I
2
C
bus as defined in this section.
