The following one bit of 8 bit data (slave device address, register address, and register data) is a bit for
handshaking. When 8 bit data is normally received, the device that receives 8 bit data generates ACK bit
(Active Low). At this time, the other device where 8 bit data was transmitted opens the data line. When the
host is communicating with other slave devices and 8 bit data cannot be normally received, this device opens
the data line and generates NACK bit (Active High) with an external pull-up resistor.

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.

[Example of detection and compensation method of blemish coordinates (X, Y) by watching]
When you adjust the blemish that appears on the screen by watching, aperture function is turned off to detect the
blemish coordinates and correct it in the following way.
1) Horizontal settings
The signal position of the blemish as Th is read by the horizontal wave form measure function of the oscilloscope.
Th for the mirror image is measured from the right edge of the image as shown in the figure below.

The following signal parameters are synchronized with the automatic controls and suppressed automatically.

2) Synchronized and suppressed with the exposure multiplication value
when AGC is maximum and the exposure multiplication value falls

2) Synchronized and suppressed with the exposure multiplication value
when AGC is maximum and the exposure multiplication value falls

3) Synchronized and suppressed with WBR when WBR goes up more

・ Shading compensation gain
The shading gain can be automatically suppressed by judging the decrease in quantities of light of subject when it is
dark. The suppression level of the shading compensation gain is calcurated by using the exposure multiplication
value and the AGC value (called “AGC_DAT” in ch.4.5.1) generated internally automatically.
The suppression that synchronizes with AGC_DAT is not done for AGC_DAT<SHD_S. The gain is suppressed by
AGC_DAT under SHD_S ≤ AGC_DAT ≤ MAX_AGC. When the exposure is insufficient with MAX_AGC, it is
suppressed by the difference the exposure multiplication value EDATA to the target value REF_IRIS. Regardless of
the AGC value, it is suppressed by the exposure multiplication value synchronization with the under-exposure in the
state of the transition of the automatic exposure control
To invalidate this automatic adjustment, it is set as SHD_H=SHD_Y=0.

Range of exposure control
The automatic exposure control synchronizes with AGC and shutter speed according to the exposure control table
of ch.4.9.1. It is used AGC_DAT for the synchronization that added AGC_TBL obtained from the exposure control
table and REF_AGC as minimum AGC gain.
AGC_DAT = AGC_TBL + REF_AGC
The upper bound of AGC, the address lower bound at the high speed shutter, and the open speed selection at a
low-speed shutter can be adjusted among ranges defined in the exposure control table.

Please set to become P_HEE+P_LEE<256.
The influence of the peak value can be considered for contrasty subject.
So as not to make the high luminance part of contrasty subject easy to saturate, P_HEE register is set to consider
the influence of a high luminance peak. Oppositely, so as not to influent the high luminance part, CLIP_IRIS
register is set to clip the upper bound before it multiplies.

4.6.4 Color suppression
There are four kinds of color suppression processing of this LSI: color suppression to the edge part, color
suppression in the high luminance region, color suppression in the low brightness region, and color suppression at
low illuminance.
・ Color suppression to the edge
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 clipping of the edge signal of brightness.

・ Color suppression in the high luminance or low brightness
It is a function to suppress the color signal in the high luminance region or the low brightness region in the image.
The color suppression level is decided by the following expressions. The color is suppressed by multiplying the
color difference gain by this color suppression level.
for high luminance region : (Brightness signal (Before the gamma) - CKI_HCL) × CKI_HGA
for low brightness region : (CKI_LCL - Brightness signal (Before the gamma)) × CKI_LGA

Linear interpolation by white balance red gain WBR

Generation of three reference point
For automatic control or fixed to REF1,2,3, then a standard color temperature, a standard 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 under the 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).
・ Gain interpolation of color difference and color difference matrix
Color difference gain toward R-Y(+) is interpolated as followed.

Each reference point is defined by 8bit and useful region is showed by the one point chain line in the above. White
balance gain is defined by 9 bit and showed by the solid line. MIN_WBR, MAX_WBR, MIN_WBB_OFST* and
MAX_WBB_OFST* are defined by 9bit which only 8bit is adjustable by the registers but LSB is fixed to 0.
RGB matrix is adjusted to keep REF_WBR1-3 and REF_WBB1-3 in the useful region as reference point.
White balance gain as WBR and WBB are increased or decresed in the above solid line based on IQ integration.
The color difference gain and matrix are calculated by interpolating between the three reference point of REF1, 2,
and 3 based on white balance red gain (WBR).
When WBR is less than REF_WBR1, it is used a parameter set for REF1. When WBR is between REF_WBR1
and REF_WBR2, it is used a interpolating parameter set from REF1 and REF2. When WBR is between
REF_WBR2 and REF_WBR3, it is used a interpolating parameter set from REF2 and REF3. When WBR is more
than REF_WBR3, it is used a parameter set for REF3.

4.7.8 Adjustment of AWB control domain
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 frame to stop the
AWB control 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 stopping AWB.
Hysteresis can be given by setting the restart judgment frame of AWB_IW_L and AWB_QW_L more greatly than
a frame of AWB_IW_S and AWB_QW_S.
Moreover, when the exposure is steady, the operation of AWB is oppressed. AWB restart operation is delayed the
predetermined number for WAIT_NUM.

4.9.1 Table of exposure control
The address on the teble is used exposure control by increased or decreased.
Actually AGC gain is added the lowest AGC gain(REF_AGC) and AGC difference on the following table.
Maximum actually AGC gain is 36 dB.But these are calculating values not dispersion of characteristic.
NTSC (270thousand pixels, 410thousand pixels CCD) exposure tables
SHT column means: Exposure time (ms)
AGC column means: AGC difference from minimum AGC gain (db)
Minimum AGC gain (dB) = REF_AGC * 0.3445 – 8.097
