Color: Up to 10 columns. Column may contain more than 10 pixel dead or out of
PRNU.
Class II is standard for color and exhibits in addition column defects
KAI 16000M/C

Cluster allowed. Cluster may contain up to 20 pixel out of PRNU spec.

30 cluster allowed

Point defects: 1500 pixel dead or out of PRNU spec. (color version up to 3000)

Column defects: Monochrome = 0.
Color: Up to 15 columns. Column may contain more than 10 pixel dead or out of
PRNU
First AND Last 300 columns out of PRNU spec of rest of CCD. They will not be saturated
as other columns with same amount of light! This can be compensated to some extend
with higher Gain. However noise will be increased. More details are available in the KAI
11002 and 16000 spec sheet.
Spectral range: 400 - 900 nm (B/W), COLOR version: RGB Bayer Mosaic Filter, see 3.7
3.1.2
Readout from CCD/svs11002 and svs16000
The output for the “U” and “F” version is as follows:
2 taps are read out and the right half of the image is mirrored starting at 1
st
line pixel # 2004
through 2672 (11 megapixel CCD). See image below. As a result either framegrabber or PC
memory must reverse the 2
nd
half in order to get a complete image as it is for the “S” version.
There the complete image is read out as usual with one tap CCD.
2 Tap output”T”, “F” and “U” version 1 Tap output “S” +”O” version
A tap balancing dll for “ Automatic tap balancing” is available ( for programming
engineers)
3.2 Signal conditioning
The analog output of the sensor is conditioned by Correlated Double Sampling (CDS) for
optimum S/N ratio. dark level drift is compensated by an “auto zero” amplifier circuit and fed into
a video ADC with 10- or 12-Bit resolution.
