HD-SDI CAMERA
45
used in countries with a 50 Hz power supply frequency.
- 1/120s for PAL models used in countries with a 60 Hz power supply frequency.
IRIS:
Iris priority mode
Variable Iris (F1.6 to Close, 18 steps),
Auto Gain and Shutter speed.
BRIGHT:
Variable Iris and Gain (Close to F1.6, 17 steps at 0dB:F1.6, 15 steps from 0 to 28
dB) according to the brightness level.
Exposure is controlled by Iris when bright and by Gain when dark.
When switching from the SHUTTER priority mode to the BRIGHT mode, the
current status will be retained for a short period of time.
Iris
The iris can be set freely by the user to 18 steps between F1.6 and Close.
The gain and shutter speed are set automatically,
ccording to the brightness of the subject.
Gain
0 / 2 / 4 / 6 … / 28dB
Defines the maximum amount of electrical gain with which the amplitude of the
incoming signal is increased.
Useful in low light situations.
The higher the gain is set the more image noise may occur.
Shutter
Shutter speeds (22 steps) : 1/1, 1/2, 1/4(3), 1/8(6) ... 1/4000(3500), 1/6000,
1/10000sec
Slow shutter speeds : 1/1, 1/2, 1/4(3), 1/8(6), 1/15(12), 1/30(25)
Values in () stand for 50Hz mode cameras.
Slow shutter speeds are useful in low light conditions, but may result in motion
blur with fast moving objects.
$
Note:
When slow shutter speeds are used, Auto Focus and White Balance may not
function fully.
Exposure Compensation
−
7 to +7 (
−
10.5dB to +10.5dB)
Exposure compensation is a function which offsets the
internal reference brightness level used in the AE mode, by steps of 1.5 dB.
Slow Shutter :
ON/OFF(AUTO mode only)
