MANU
You can set the SPEED value in units of 1H
(Cont.)
(horizontal scanning time: 29.63 µs).
For example, use of this mode reduces noise
(horizontal patterns) when shooting a computer
screen display.
To set the shutter speed
1 Display OFF by pressing the DATA UP and
DOWN buttons together.
2 Select the SPEED value by pressing the DATA
UP button while observing the noise on the
monitor screen so that you can obtain the image
with minimum noise. Each time you press the
button, the value changes in units of 1H in the
range from 560H through 1H.
To convert the value into the shutter speed
Example: When the value is set to 250H
250 × 29.63 µs (1H) + 18.42 µs (constant)
= 7425.92 µs = Approx. 0.0074 seconds

Selection Function
CCD-IRIS Automatically adjusts the luminance level for
optimum output level. The shutter speed changes in
the range from 1/60 to 1/10000.
The SPEED display indicates "- - -".
For example, this function is useful for microscope
adaptor applications. When shooting with a
microscope not equipped with the auto-iris lens, the
luminance level that is just right for the human eye is
often too bright for the video camera.
When CCD-IRIS is selected, the electronic shutter
automatically decreases excessive incident light to
an appropriate level for the video camera. This
function is also useful for cutting out excessive
incident light that is not cut out by the auto-iris lens
in scenes containing very bright patches (such as
snow, or sea water reflecting sunlight).
You can use CCD-IRIS in combination with AGC
and/or AUTO IRIS control.
