Outline
The following operation allows the alignment of the shutter
speed of the camera with the variable scanning rate of a
computer monitor or display.
When a computer monitor screen or display is shot with the
camera, a bright horizontal line indicating excessive exposure
is displayed in cases when the scanning rate of the monitor
is faster than the shutter speed of the camera. A dark
horizontal line indicating insufficient exposure is displayed in
cases when the monitor's scanning rate is slower than the
camera's shutter speed.
The scanning frequency of a monitor varies due to various
reasons during the computer operation. Adjust the scanning
rate to obtain a stable image while observing the image in
the viewfinder or LCD monitor.
Variable Scan [V.SCAN]
• Basic operation
Set the SHUTTER item on the CAMERA OPERATION menu
screen to VARIABLE. Then rotate the SHUTTER dial upward
or downward to change the shutter speed.
(The speed is displayed in the viewfinder or LCD monitor.)
• Compatible frequencies
The variable scan function is compatible with scanning
frequencies in the following range.
60.1Hz to 2084.6 Hz
CAUTION:
This function is not compatible with slow-speed computer
monitors with a vertical scanning speed of 50 Hz.
