6-1-2 Slow Shutter Function
Slow Shutter is a function for obtaining quick motion
effects with afterimaging by using the LFE function (Long
Frame Exposure, frame storage mode) of the HDC-F950.
To use the Slow Shutter function, you must to install the
HKSR-101 Optical Interface Unit as well as the HKSR-
102 and connect this unit to the HDC-F950 by optical fiber
cable.
A certain number of frames of the video shot on the HDC-
F950 are stored in the CCDs of the camera, as specified on
Relation of the number of stored frames to the number of frames shot and the number of
playback frames (outline of Slow Shutter)
If you use the Slow Shutter function to shoot in the 30P
format (the camera shoots at 30 FPS, or in other words at
a system frequency of 30 frames), then setting the number
of stored frames to 3FRM gives a number of frames that is
equivalent to 10 FPS.
Three frames of shot video are stored in the camera and
transferred as a single frame. This frame is called an
effective frame. In addition to the effective frame, two

the HDC-F950. After the stored data is transferred to the
VTR, only effective frames are stored in memory of the
HKSR-102 and recorded onto tape. The number of frames
which are stored is displayed in units of FRM (frames).
When installing the HKSR-101, refer to the Installation
Manual of the HKSR-101.
frames without video signals are transferred. These frames
are called ineffective frames. This unit stores only
effective frames in memory and records them onto tape.
When the tape is played back, a quick motion effect of 3
times normal playback speed is obtained.
