Synchro scan
Set the shutter speed of the synchro scan (used
when shooting a television or computer monitor) in
the setup menus, SCENE FILE screen, SYNCRO
SCAN. (Page 97)
Adjust the shutter speed to match the frequency
of the television or computer monitor to minimize
the horizontal noise that appears when shooting
such subjects.
When the OPERATION TYPE option in the
SCENE FILE screen (Page 97) is set to FILM
CAM, the shutter opening angle can be adjusted
from 10° to 360° in 0.5° steps.
Example: When the recording frame rate is set to
25 fps and the exposure time is halved, 1/25 ÷2 =
1/50 = 180° (1/25 = 360°)
In the default setting (180°), this becomes 1/2 of
the exposure time. If it were 90°, it would be 1/4,
and if it were 45°, it would be 1/8 of the exposure
time.
(Shutter opening angle: This is equivalent to the
shutter speed of a film camera, and a wider angle
results in a longer exposure to light.)
If the shutter speed is displayed in blue
characters followed by (1/50), you cannot change
the shutter speed in the blue characters while the
current recording format is used. The speed is
fixed at (1/50).
You can change the progressive mode in
the setup menu with REC FORMAT in the
RECORDING SETUP screen. (Page 103)
