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 X vertical 582), the sensor
provides a stable B/W image.

The image area is divided mto 10X 10 segments. Tk ~ment’s voltage is the average output voltage of all the
pixels within the segment. PRNU is defined by (Vmax –
Vmin)/Vo, where Vmax and Vmin are the maximum and
the minimum values of each segment’s voltage respectively, 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 ~t as 10 times, compared to standard level.
The average output voltage under a non-e-re @lticm.
The image area is div!ded into 10x 10 segments. OSNU is

that is the average output voltage over al I pixels in the
segment.
The average output voltage when a 1 COO Iux light source
attached with a 90% reflector is imaged by a lens of F4,
f50 mm.
The sensor is adjusted to position a V/l O square at the
center of image area Mere V is the vetilcal length of the
image area. SMR is defined by the ratio of the output
voltage detected during the vertical blanking pericxl to the
maximum of the pixel voltage in the V/l O square.
The sensor is ex~d at the exmsure level corresWnding to the standard condition preceding ncm-exposure condition. Al is defined by the ratio between the output voltage 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 exDsure at the standard condition and the exposure at a
mint where a blmming is observed.
