Flicker-free mode

Prevents flickering caused by fluorescent lighting in area with 50 Hz.

When the shutter speed is set at 1/100 sec (flicker-free mode), flickering is eliminated.

•When looking at the picture on the monitor while the electronic shutter is being used, the object movement appears to be discontinuous.

For example: in shutter speed of 1/2000 sec. Since the image for 1/2000 sec is taken out every 1/60 sec, this phenomenon occurs.

•When high-speed shutter is used, light may not be suffi- cient.
