1) Recording a subject whose one end is located closer

to the Movie Camera and the other end farther away
from it

≥

Because Auto Focus makes adjustments at the centre

of an image, it may be impossible to focus on a subject
that is located in both foreground and background.

2) Recording a subject behind dirty or dusty glass

≥

Because the focus is on the dirty glass, the subject

behind the glass will not be focused.

3) Recording a subject in dark surroundings

≥

Because the light information that comes through the

lens decreases considerably, the Movie Camera
cannot focus correctly.

4) Recording a subject that is surrounded by objects

with glossy surfaces or by highly reflective objects

≥

Because the Movie Camera focuses on the objects

with glossy surfaces or on highly reflective objects, the
recording subject may become blurry.

5) Recording a fast-moving subject

≥

Because the focus lens inside moves mechanically, it

cannot keep up with the fast-moving subject.

6) Recording a subject with little contrast

≥

Because the Movie Camera achieves focus based

upon the vertical lines of an image, a subject with little
contrast, such as a white wall, may become blurry.

White Balance Adjustment

Depending on the type of light source, the colours recorded
by the Movie Camera may be affected. In some cases,
images may be recorded with bluish or reddish hue. To
minimize the effect of light on the subject’s colour, what is
called White Balance Adjustment becomes necessary.

White Balance Adjustment

White Balance Adjustment recognizes the colour of light and
makes adjustment so that the white colour will become pure
white.

Automatic White Balance Adjustment

This Movie Camera stores settings that are optimal for
several kinds of general light sources. The Movie Camera
determines the hue of light that it receives through the Lens
and White Balance Sensor

(

, thereby judging the

recording condition, and selects the closest hue setting. This
function is called Automatic White Balance Adjustment.
However, since white balance settings for only several kinds
of light sources are stored, the Auto White Balance Function
does not operate properly when recording occurs under light
that is out of the range of the setup values.

Time Code

Time Code signals are data that indicate time measured in
hours, minutes, seconds, and frames (25 frames per
second.) If this data is included in a recording, an address is
assigned to each image on the tape.

≥

The Time Code is automatically recorded as a part of the
sub-code at each recording.

≥

When a new (previously unrecorded) Cassette is inserted,
the Time Code automatically starts from zero.If a recorded
Cassette is inserted, the Time Code picks up from the point
where the last scene was recorded.(In this case, when the
Cassette is inserted, the zero display [0h00m00s00f] may

appear, but the Time Code starts from the previous value.)

）

≥

The Time Code cannot be reset to zero.

≥

Unless the Time Code is continuously recorded from the
beginning of a tape, accurate editing may not be possible.
To ensure that the Time Code will be recorded with no
breaks, we recommend the use of the Camera Search
Function

(

18)

or the Blank Search Function

(

27)

before recording a new scene.

Memory Stop Function

The Memory Stop Function is useful for the following
operations.

Rewinding or fast-forwarding a tape to a desired
position

Set [DISPLAY SETUP] >> [C.DISPLAY] >>
[MEMORY].

Reset the Tape Counter to zero at the tape
position from which you want to play it back
later.
