ªDigital Video System

In a digital video system, images and sounds are converted into digital signals and recorded on a tape. This complete digital recording is capable of recording and playback with minimal image and sound deterioration.

In addition, it automatically records data, such as Time Code and date/time, as digital signals.

Compatibility with S-VHS or VHS Cassettes

Because this Palmcorder employs a digital system for recording image and sound data, the cassette is not compatible with conventional S-VHS or VHS video equipment that employs an analog recording system. The size and shape of the Cassettes are also different.

Compatibility with Output Signals

Because AV signal output from the AV signal output jack is analog (the same as conventional video systems), this Palmcorder can be connected with S-VHS or VHS VCR or a TV for playback. (l44)

ªFocus

Auto Focus Adjustment

The Auto Focus System automatically moves the internal focusing lens forward or backward and adjusts the focus so that the subject can be seen clearly.

However, the Auto Focus System does not function properly for the following subjects or under the following recording conditions.

Please use the Manual Focus Mode instead.

1)Recording a subject whose one end is located closer to the Palmcorder and the other end farther away from it

Because Auto Focus makes adjustments at the center 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 in focus.

3)Recording a subject in dark surroundings

Because the light information that comes through the lens decreases considerably, the Palmcorder may not focus correctly.

4)Recording a subject that is surrounded by objects with glossy surfaces or by highly reflective objects

Because the Palmcorder 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 may not be able to keep up with the fast-moving subject.

6)Recording a subject with little contrast

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

ªWhite Balance Adjustment

Depending on the type of light source, the colors recorded by the Palmcorder 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 color, what is called White Balance Adjustment becomes necessary.

White Balance Adjustment

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

Auto White Balance Adjustment

This Palmcorder stores settings that are optimal for several kinds of general light sources. The Palmcorder 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 Auto White Balance Adjustment.

However, since white balance settings for only certain 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 setting values.

ªTime Code

Time Code signals are data that indicate time measured in hours, minutes, seconds, and frames (30 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 (l20) or the Blank Search Function (l30) before recording a new scene.

ªMemory Stop Function

The Memory Stop Function is useful for the following operations.

Rewinding or fast-forwarding a tape to a desired position

1Set [DISPLAY SETUP] >> [C.DISPLAY] >> [MEMORY].

2Reset the Tape Counter to zero at the tape position from which you want to play it back later. (l10, 16)

3Start playback or recording.

4When playback or recording is over: slide the [OFF/ON/MODE] Switch from [ON] to put the Palmcorder in the VCR Mode.

The [VCR] Lamp lights up.

5Rewind the tape.

The tape automatically stops approximately at the position where the counter was set to zero.

Stopping editing automatically during audio dubbing

1Set [DISPLAY SETUP] >> [C.DISPLAY] >> [MEMORY].

2Reset the Tape Counter to zero at the position where you want to stop editing.

3Play back the still pictures where you want to start audio dubbing.

4Start audio dubbing. (l34)

Audio dubbing automatically stops at the position where the counter was set to zero.
