DESCRIPTION
LZ2346 is 1 /3-type (6.0 mm) solid-state image
sensor that consists of PN phote-diodes and
CCDS (charge-coupled devices) driven by only
positive voltages. Having approximately 220000
pixels (horizontal 384 vertical 582), the sensor
provides a stable B/W image.

The image area is divided mto 10X 10 segments.
voltage is the average output voltage of all the
pixels within the segment. PRNU is defined by (Vmax
where Vmax and Vmin are the maximum and
the minimum values of each segment's voltage respec-
tively, when the average output voltage Vo is 150 mV.
The image area is divided into 10x
10
segments.
The saturation signal is defined as the minimum of each
segment's voltage which is the average output voltage of
all the pixels within the segment, when the exposure level
is
as 10 times, compared to standard level.

that is the average output voltage over al pixels in the
segment.
The average output voltage when a 1 COO

V is the
length of the
image area. SMR is defined by the ratio of the output
voltage detected during the vertical blanking
to the
maximum of the pixel voltage in the V/l O square.
The sensor is

dition. Al is defined by the ratio between the output volt-
age measured at the 1st field during the non-exposure
period and the standard output voltage.
The sensor is adjusted to position a V/l O square at the
center of image area. ABL is the ratio between the
