Shutter Settings

This section covers the settings for electronic shutter
speed, CLS (clear scan ) and EVS function.
The new value for the shutter speed or clear scan
frequency and EVS setting remains set until changed,
even when the camcorder is powered off.
Shutter speeds
There are five shutter speeds, from
1

s (DSR-300P) to

speed reduces blurring when shooting a fast-moving
subject. It is also possible to reduce flicker when
shooting under fluorescent lighting by changing the
shutter speed.
CLS (Clear Scan) function
When shooting a computer screen or projected image,
horizontal bands may appear in the camcorder image.
This is because the vertical scan frequency of the
computer-generated image is different from the
vertical scan frequency of the video system. The clear
scan function allows you to select a vertical scan
frequency to reduce this interference.
EVS (Enhanced Vertical Scan)
This function enhances the vertical scan resolution
from 400 to 450 lines (or 450 to 530 lines) to reduce
flicker. However, this increases the aliasing.

Notes on setting the shutter speed
• The faster you make the shutter speed, the darker the
image becomes. Check the brightness in the
viewfinder, and if necessary increase the lighting
level or adjust the iris.
• When the shutter speed is very fast, shooting a high
intensity subject may cause long vertical tails to
appear on the highlights (smear).
Note on setting the CLS function
The vertical scan frequencies of computer screens
vary, and it may not be possible to eliminate the
interference patterns entirely. Note also that the
vertical scan frequency may change depending on the
software being run.
