DESCRIPTION
Two-power supply
V and +12 V) operation
1 / 3 type B/W CCD Area Sensor for EIA
PIN CONNECTIONS
is a 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 190000
pixels (horizontal 384
X
vertical 492), the sensor
provides a stable B/W image.

standard output voltage is defined as 150
by the
average output voltage under uniform illumination.
q
The standard exposure level is defined when the average
output voltage is 150
under uniform illumination.

1. Ta :
2. The image area is divided into 10x 10 segments. The seg-
7
ment's 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 150mV.
3. The image area is divided into 10x 10 segments.
8
The saturation signal is defined as the minimum of each
segment's voltage which is the average output voltage of
all the pixels
the segment, when the exposure level
is set as 10 times, compared to standard level,
4. The average output voltage under a non-exposure condition.

5. The image
is
into 10x
10
segments. DSNU is
defined by
under the non-exposure con-
dition where Vdmax and Vdmin are the maximum and the
minimum values of each segment's voltage, respectively,
that is the average output voltage over all pixels in the
segment.
The average output voltage when a
ight source
attached with a
reflector is imaged by a lens of F4,
f50 mm.
The sensor is adjusted to
a V/l O square at the
center of image area where V is the vertical length of the
image area, SMR is defined by the ratio of the output
voltage detected during the vertical blanking period to the
maximum of the pixel voltage in the V/l O square.
The sensor is exposed at the exposure level correspond-
ing to the standard condition preceding non-exposure con-
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 ex-
posure at the standard condition and the exposure at a
point where a blooming is observed.
