NOTES :
1. The average output voltage of G signal in the central
area (H/10, V/10) under uniform illumination.
The standard exposure conditions are defined as when
V
O
is 150 mV.
2. The average output voltage of G signal in the central
area (H/10, V/10) under 10 times exposure of the
standard exposure conditions.
3. The average output voltage of G signal in the central
area (H/10, V/10) when a 1 000 lux light source with a
white board of 90% reflector is imaged.
4. The resolution in the central area (H/10, V/10) at which
the image of the TV resolution chart (ex. EIAJ test chart)
can be distinguished on the B/W video monitor when
converted into composite video signals.
5. The resolution in the peripheral area (image height : Y =
0.8) under the conditions mentioned above.
6. Defined by the following formula at the brightness of
standard output voltage : (Vco/Vce) x 100 [%]
Vco : Output voltage at edge (image height : Y = 0.8) of
the image (at video output).
Vce : Output voltage at center of the image (at video output).
7. The difference between the center position of image and
that of the monitor. This is the ratio for the horizontal
underscanning monitor size which includes the decentering
eccentricity when turning the lens head one time.
8. Total current of analog and digital power supplies, in the
dark and at the standard load conditions.

1. TV distortion is defined by the formula, (∆y/y) x 100 [%]
at capturing rectangular pattern sized horizontal by
vertical as 4 by 3.
"y" is defined as the vertical height of the center of the
horizontal line.
∆y is defined as the difference between the vertical height
of the center of the horizontal line and an edge of it.

2. The best focus point of an object can be obtained by
turning the lens head within this range.
3. Torques which are necessary for turning the lens.
