KC73129UC 1/3 INCH CCD IMAGE SENSOR FOR PAL
TEST METHODS
1. Measure the light intensities(L) when the averaged illuminance output value(Y) is the standard illuminance
output value, 150mV(Y
A
) and when half of 150mV(1/2 Y
A
).

2. Adjust the light intensity to 10 times that of Y signal output average value (Y
A
= 150mV) , then test Y signal
minimum value (Y=Y
SAT
).
3. Adjust the light intensity to 500 times that of Y signal output average value (Y
= 150mV), then remove the
read-out clock and drain the signal in photosensors by the electronic shutter operation in all the respective
horizontal blanking times with the other clocks unchanged. Measure the maximum illuminance output value
(Y
SM
).
4. Adjust the light intensity to 1000 times that of Y signal output average value (Y
A
= 150mV), Then confirm that
Blooming dose not appear.
5. Measure the maximum and minimum illuminance output value (YMAX, YMIN) when the light intensity is
adjusted to make Y to be Y
A
.
U = (YMAX - YMIN) /YA X 100. (%)
6. Measure Y signal output average value Y
D
[mV] with the horizontal idling time transfer level as reference,
when the device ambient temperature is 50
°
C and all of the light sources are shielded.
7. Adjust the light intensity to make Y=Y
A
. Measure the difference value (
Y
F
) between the averaged illuminance
signal values of the even and odd fields.
8. Adjust the light intensity to make Y=Y
A
.Then insert red (R) and blue (B) optical filters respectively, measure
the differences (
C
R
,
C
B
) between the chroma signal values in even and odd fields and the C signal
output averag value (C
R
, C
B
).

9. Adjust the light intensity to make Y=Y
A
. Then test maximum(C
R,MAX
and C
B,MAX
) and minimum(C
R,MIN
and C
B,MIN
) values of chroma signals from R-Y and B-Y channels.

10. Adjust the light intensity to make Y = 150mV(Y
L
). Then insert white (no filter, W), red(R), green(G) and blue(B)
optical filters respectively, measure the illuminance signal difference values (
