Shading compensation
Quantities of light might attenuate in the part around the lens when the wide-angle lens is used.
This can be eased by the shading compensation function. To use the shading compensation function, the
compensation gain characteristic is set to the second r radius power from the center part by the straight line. It
provides for each range of the radius of the second power with SHD_RNG1 to 12, and the gain in each division
point is set with SHD_OFS0 to 13.

The threshold for the line crawl detection is adjusted by the LINE_U register. If a big value is set to LINE_U, it

Explanation
Generation of three reference point
A standard color temperature, the state of the lighting, and the object are defined by three conditions (a low color
temperature, a middle level, and the high color temperature). The reference parameter that can adjust the white
balance is made at each color temperature.
White balance gain WBR and WBB are increased and decreased at automatic control so that the integrated value
may approach the starting point (no color) within the range of the MIN/MAX restriction. The color difference gain
and the color difference matrix gain are calculated by interpolating between the three reference point of REF1, 2,
and 3 based on white balance red gain (WBR).

Color suppression
There are four kinds of color suppression processing of this LSI: high luminance and partial color suppression, low
brightness partial color suppression, color suppression at low illuminance and edge part color suppression.
・ Edge color suppression
It is a function to suppress the false color generated in the edge part of the horizontal and vertical direction.
The color is suppressed by suppressing the color difference gain (The gain of one or less is multiplied) by the
signal generated putting the gain after a low-level part of the edge signal of brightness is done in the clip.

・ High luminance and low brightness partial color suppression
It is a function to suppress the color signal of the high luminance part and the low brightness part in the image.
The color suppression level is decided by the signal calculated by the following expressions. The color is
suppressed by multiplying the color difference gain by this color suppression level.

Adjustment of AWB multiplication frame
Color difference information on the pixel that enters in the set frame is averaged on the IQ axis, and the error
margin of the white balance in the no coloring part is calculated. The multiplication frame is set by four parameters
of AWB_IP, AWB_IM, AWB_QP, and AWB_QM as shown in figure below (a). Moreover, the extraction condition
in the no coloring part can be adjusted in proportion to the color temperature as shown in figure below (b).

Adjustment of AWB fixation frame
This LSI adjusts the gain of R and B based on the error margin from the starting point of the IQ integrated value
(color no) and adjusts the white balance. As a result, when the IQ integrated value enters in a final frame to which
I and Q are set with both AWB_IW_S and AWB_QW_S, the AWB operation is stopped.
The AWB operation is restarted when going out outside the restart judgment frame to which either of I or Q of the
IQ integrated value is set with AWB_IW_L and AWB_QW_L by subject's changing after fixing AWB. Hysteresis
can be given by setting the restart judgment frame of AWB_IW_L and AWB_QW_L more greatly than a final
frame of AWB_IW_S and AWB_QW_S.
Moreover, when the exposure is steady, the operation of AWB is oppressed. AWB operation is delayed the
predetermined number for WAIT_NUM if the error margin of exposure level and exposure target value REF_IRIS
is CTLD_AW or less after fixing AWB.

AWB operation speed
The AWB operation speed can be adjusted by setting the following settings.
It is possible one time to thin out as the operation of AWB is several-time by setting it to the CMP_CT register by
the number of the AWB operation interval of fields. The IQ integrated value is decreased in the setting of the
IQ_LPF register and the change according to peculiar data can be decreased to past data by smoothing it.

The amount of the change that increases and decreases by the AWB adjustment once can be adjusted by
adjusting proportion coefficient K_WBR_H and K_WBB_H in that case though white balance gain WBR and
WBB are increased and decreased in proportion to the amount of the error margin from the starting point of the IQ
integrated value.

Self adjustment of parameter that synchronizes with automatic control
This LSI synchronizes with the automatic control of building into, and adjusts the following signal processing

Range of brightness multiplication for AWB
Quantities of light in surrounding

It synchronizes with level HPEAK LPEAK in brightness.
Please refer to the chapter of the explanation of the white balance for the adjustment of the AWB integrating range.
・ Color suppression level
Color suppression level can be automatically made strong by judging the decrease in quantities of light of subject
from the AGC value and the exposure multiplication value when it is dark. To invalidate this automatic adjustment,
it is set as COL_H=COL_Y=0.

There is no regulating function with the reference color bar at a digital output because there are neither a gain with
the video filter nor a possibility of attenuation by the transmission route etc.
