Flash band compensation (FBC) function
The camera is equipped with a function for compensating and reducing band-like interference (called “ash band”) that occurs due to the MOS pickup
device when shooting in environments where ash strobe light such as that from still cameras is present.

NOTE
t When the ash strobe lights, the following phenomena may occur. These are due to the ash band compensation function and are not malfunctions.
- Moving subjects look as if they have been stopped for a moment.
- The resolution drops when the ash strobe lights.
- Horizontal lines appear in the video when the ash strobe lights.
- Flash bands appear only in images shot at the time the ash strobe lights.
Using the ash band compensation function
The ash band compensation function is activated when there are large changes in brightness at the bottom of the screen regardless of whether there
is ash strobe light. The ash band compensation function may be activated depending on the shooting environment such as where a bright window has
zoomed in and then out. So, we recommend use of this function in shooting environments where ash strobe lighting is anticipated.
Even if ash strobe lighting occurs, sufcient ash band compensation function effect may not be obtained in some shooting environments.
Flash band compensation function operation conditions
f The ash band compensation function can be used when all of the following conditions are satised.
- Either in 59.94i, 59.94P, 50i, or 50P mode
- Scan reverse and digital zoom functions are not operating
- <SHUTTER> switch is <OFF>
f Even if the ash band compensation function is enabled, the ash band compensation function is forcibly disabled if the camera is changed to a mode
where the ash band compensation function cannot be used.
To use the function again, return to a mode where the function can be used, and press the USER button to turn on the ash band compensation
function.
The ash band compensation function is disabled once the power is turned off.
f Even if the ash band compensation function is active, the ash band compensation function temporarily turns off when the <SHUTTER> switch is
turned <ON>. The ash band compensation function turns on again by turning the <SHUTTER> switch <OFF>.
