(OPERATION) menu.
ADD: After a Continuous mode operation to
specify a shutter value in the [deg] field, you
can use ADD to register that value as a new
shutter step. If eight shutter step values have
been already registered, "STEPS FULL"
appears, and the new value is not registered.
In that case, use DELETE to delete an
unneeded shutter step value and try again.
DELETE: Deletes the shutter step value
displayed in the [deg] field by a step
operation.
See "Shutter Settings" (page 42) for more
information about shutter step values.
FRAME RATE
When the optional HKSR-9002 is installed, select
the frame rate (number of frames to shoot), for
when Select FPS is selected as the video format.
You can select from the ranges in the following
table.
Selected format
S23.98PsF/S24PsF 1 to 24 FPS (1 to 24 frames)
S25PsF
S29.97PsF/S30PsF 1 to 30 FPS (1 to 30 frames)
S50P
S59.94P/S60P
Note
When you have selected a format other than Select FPS,
the frame rate is displayed in parentheses and cannot be
changed.
COMP MODE
When the optional HKSR-9002 is installed, you
can compensate for changes in the video level
when the frame rate (number of frames to shoot)
is changed. There are two compensation modes,
which use either the shutter angle or electrical
gain.
ANGLE (angle compensation mode): When the
frame rate is changed, the video level is held
constant by automatically adjusting the
shutter angle.
Notes
• In angle compensation mode, the frame rate
cannot be changed to a low value when the angle
approaches 0°, and the frame rate cannot be
changed to a high value when the angle
approaches 360°.
70 Detailed Shutter Settings
Selectable frame rates
(number of frames to
shoot)
1 to 25 FPS (1 to 25 frames)
1 to 50 FPS (1 to 50 frames)
1 to 60 FPS (1 to 60 frames)
• In angle compensation mode, the shutter is
automatically switched to ON.
GAIN (gain compensation mode): When the
frame rate is changed, the video level is held
constant by automatically adjusting the
electrical gain. The shutter angle is held
constant.
Notes
• Depending on the selected format and FPS value,
the dynamic range (latitude) may decline up to a
1
maximum of / . Be aware of this when you are
2
shooting scenes with high contrast.
• When the unit is shipped from the factory, the
frame rate ranges that can be selected for the
Select FPS function (see page 103) are limited.
When COMP MODE is set to OFF or ANGLE, it
is not possible to select a frame rate of 8 FPS or
below. This limitation is intended to prevent
degraded video quality. To remove this
limitation, change the setting of FPS LIMITER
on the <OTHERS 2> page of the
MAINTENANCE menu from LIMIT to FREE.
However, if you do set the frame rate to 8 FPS or
below, noise will become more prominent in the
picture. When you change the setting of FPS
LIMITER from FREE back to LIMIT, COMP
MODE is automatically set to OFF.
