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

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 of the image (at NTSC

video output).

Vce : Output voltage at center of the image (at NTSC

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.

NOTES :

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.

* Be careful not to remove the lens head by turning it

counterclockwise too much when adjusting macro.
