1. Selecting Scene File
1-1. Scene Files and their features
In AJ-PX270, setting values for adjusting the image quality are preset in advance as Scene Files of six types.
With Main Menu [SCENE FILE] [FILE SELECT], Suitable Scene Files for recording conditions or operator’s
intended images can be called. Also, by assigning [SCENE FILE SEL] to one of the USER buttons, Scene files canrapidly recalled with it.

F1:

F2: FLUO.

F3: SPARK

F4: B-STR

F5: CINE V

F6: CINE D

Suitable for normal recording.
Gamma is “HD NORMAL” and the other parameters are factory default settings.

Suitable for recording where the characteristics of fluorescent lamps are taken into consideration(e.g. shooting indoors).
Most of the parameters are equal to Normal but the MATRIX is for fluorescent lighting.
This is not particularly necessary under the fluorescent lighting close to the natural light.
But it is suitable for the recording conditions under which the color reproduction is poor due toblue-intense fluorescent lamps.
Suitable for recording in SD resolution with richer color level and sharper contrast.
The picture will be showy with vivid colors and give a bright impression.

Suitable for recording where the gradation is expanded on dark parts of the image (e.g. shooting
a sunset scene).
This is effective if being used when dark parts are difficult to see or both bright and dark scenes
need to be seen in detail in shooting at sunset, in the theater or at a wedding.
Suitable for movie-like recording where importance is placed on contrast.
This has the Gamma curve to make a movie-like picture using a video camera (V).

Suitable for movie-like recording where importance is placed on the Dynamic Range.
This Gamma gives priority to the Dynamic (D) Range and maintains the gradation that ranges
evenly from low to high level.
If the post-production editing or the kinescope is planned, this can be selected because
recording in this mode will make such post-processing easier and smoother. Also, it will createa unique atmosphere which is sometimes used as an effect.

* Even if the Scene File is changed, [SYSTEM MODE] will not be changed.

52. Expressing the texture of objects
2-1. Detail enhancement
When expressing the outline or surface texture of an object, faint reflection of light may be intensified or, to the contrary,
the picture may look blurred. This is a phenomenon caused by the strength / weakness of Detail signal to intensify
the video signal for the object’s outline. Adjustment of Detail signal can make the object’s luster or texture look morenatural.
MASTER DTL: +31

MASTER DTL: -31©Panasonic Corporation

For AJ-PX270 camera, the adjustment of Detail is usually made by setting MASTER DETAIL (intensity of the effect)
and DETAIL CORING. DETAIL CORING is a function to set the level of signal (including noise) which suppresses
the Detail effect.
For further information, please refer to “2-4. More advanced settings for Detail”.
On the other hand, as an advanced setting, DETAIL (both horizontal and vertical directions) and V DETAIL (verticaldirection) are mainly used. Within a certain range of levels of outline signal, the adjustment can be made balancing
the horizontal and vertical effects against each other.
If the setting value is set to a positive value, which is greater than the center value “0” (zero), that is, if the Detail level isincreased, the edges of video signal will be intensified horizontally and vertically and the picture will look sharper withan enhanced outline of an object. To the contrary, if it is set to a negative value, that is, if the Detail level is decreased,
the outline enhancement will be suppressed and the picture will look softer.
After the Detail is adjusted, if there is a noticeable difference in sense of resolution between the horizontal and verticaldirections, use V DETAIL to make adjustments to the vertical Detail only.

2-3. Technical description : DetailThis is an outline signal which is added to a video signal.
If the Detail level is increased, the edges of video signal will be intensified and outlines in the picture will look sharper.
If the Detail level is decreased, the edges of video signal will be weakened and the picture will look softer with its
outline enhancement suppressed.

2-4. More advanced settings for Detail : Detail Coring, Skin Tone Detail
Detail Coring
Outline compensation can be performed by adjusting the Detail, and enhanced outlines enable clear representation ofimages. But at the same time it may make a whole picture look coarse. This is because added Detail signal will
also work on low-level signals including noise.
Detail Coring function can adjust the range of adding the Detail signal and reduce the noise caused by adjusting the
Detail.
Noise is a low-level signal. So, when the Detail Coring is set to a higher level than noise signals, the Detail signal will
work only on high-brightness signals to be intensified, not on the noise. By this adjustment, the outline of an object
will be enhanced and its texture will look the same while the increase of coarseness on the whole picture issuppressed.
In some cases, this adjustment of Detail range by Detail Coring is effective to reduce the noise that has become
noticeable due to GAMMA setting. Moreover, with the Skin Detail turned ON, graininess of human skin color can belowered and, also in representing the images of people, it is possible to make the texture look natural depending on
the situation.

Skin Tone Detail
When there is grainy noise on human skin color areas, Skin Detail function can decrease the Detail of those areas tolower their graininess.
However, depending on the situation, setting the Skin Detail or Detail Coring may even affect natural light and shade,
which characterize the human skin or the texture of an object, and, as a result, the natural representation may become
impossible. So it needs to be checked every time this adjustment is made.

3. Expressing the gradation of a picture (Knee, Gamma)
3-1. Knee adjustment
Due to the sunny weather or the lighting, “blown-out highlights” sometimes occur, where bright areas look completely
white.
This is a phenomenon caused by the luminance signals that are out of the camera’s Dynamic Range (processing
range). In order to put such high-brightness input signals within the Dynamic Range, Knee function can be used tocompress the gradation. However, the color gradation is also compressed at the same time by this function. So,
depending on the scene, the color may become lighter. In that case, setting [KNEE MASTER SLOPE Rch] and[KNEE MASTER SLOPE Bch] will enable the adjustment of color.

3-2. Technical description : Knee
Knee is a function to compress the luminance signal of a certain level or higher so that it can be output at a level ofabout less than 109% (white clip) in order to put the brightness of an object within the Dynamic Range.
Knee Point is a setting about which level to start the compression from. It is said that the brightness of human skin is
about 85%, so professional video cameras are designed so that their settings can be set for the brightness of thesame level as human skin or higher. That is, without affecting much the gradation expression of human skin, thegradation of brighter areas like clouds in the sky can be expressed well by using Knee.
Knee Slope indicates how much to be compressed, which means a slope of the brightness curve from Knee Point to
the maximum of Dynamic Range. Generally, when a scene includes high-brightness areas, the Knee Point is set toa lower value to prevent blown-out highlights. On the other hand, when a scene does not include such areas, theKnee Point is set to a higher value to prevent the gradation of middle-brightness areas from being compressed.

3-4. Gamma adjustment
There are cases where the color and contrast, which look natural to the eye, are not fully reproduced on the picture.
An effective way for these cases is to adjust the gradation of output signal. Select a suitable Gamma curve according
to the scene. AJ-PX270 offers seven types of Gamma curves.
(Main Menu [SCENE FILE] [GAMMA MODE SEL])
HD:
This is a video Gamma characteristic for HD (High Definition).
This Gamma complies with the standards defined by ARIB, EBU, SMPTE, etc. Use this for the purpose of normal
HD shooting.
SD:
Gain is increased for dark areas more than HD Gamma.
This Gamma curve can be used for shooting in SD mode, or for HD shooting that needs the same Gamma as usedin SD shooting.
FILM LIKE 1:
Compared with HD Gamma, this has the characteristics by which the gradation of the highlights can be reproduced
better. Using this Gamma curve which gently slopes for the low-brightness area makes the picture look calm.
Contrast becomes sharper and the gradation expression of the middle- and high-brightness areas (face, etc.) is
extended.
FILM LIKE 2:
Compared with FILM LIKE 1, this has the characteristics by which the gradation of the highlights can be reproduces
better.

FILM LIKE 3:
Compared with FILM LIKE 2, this has the characteristics by which the gradation of the highlights can be reproduce
better.

FILM-REC:
Film-use cine Gamma characteristics.
This Gamma gives priority to the Dynamic Range and maintains the gradation that ranges evenly from low to highlevel. It creates a unique atmosphere which is sometimes used as an effect.
VIDEO-REC:
Video-use cine Gamma characteristics.
This is a Gamma curve to make a movie-like picture using a video camera. It creates a picture where more
importance is placed on contrast than in normal video mode recording.

3-5. Technical description : Gamma
Gamma is a value that indicates the relationship between the levels of input and output signals of the camera ormonitor TV. Generally, it is said that linear Gamma (γ = 1) represents the image reproduction closest to the one seenby the eye. However, the monitor TV has the Gamma characteristics that make the output level of its signal higher
and higher as the input level increases. (γ = approx. 2.2) So the camera corrects its Gamma and performs therecording so that the Gamma will become close to linear in the end. (normally γ = 0.45, reciprocal value of 2.2)

3-6. DRS: Useful for shooting the scene with large contrast between bright and dark areas
By starting up DRS (Dynamic Range Stretcher) function, the Gamma curve and Knee Slope are estimated according
to the signal level of each pixel and adjusted in real time. This allows both dark and bright areas to maintain the highlevel of gradation expression and can minimize not only crushed blacks and blown-out highlights but also huecompression.

DRS: ONDRS EFFECT DEPTH : 3[SCENE FILE][DRS］ OFF / ON
Enables / disables the Dynamic Range Stretcher function.
[DRS EFFECT DEPTH］ 1 / 2 / 3
Sets the compression level of high-brightness areas by Dynamic Range Stretcher function.
Compressing the video signal level of high-brightness area, which is so bright that it would be represented asblown-out highlights in normal recording, enables the Dynamic Range to be expanded. A larger setting value has
more effect of DRS (compression level of high-brightness area) to make the Dynamic Range wider in appearance.
However, if this level is higher, the noise on dark areas may also be intensified. In addition, depending on the scene,
its picture may look unnatural. So it needs to be checked every time this adjustment is made. Also, when there isan extremely dark or bright area, or when the brightness is not enough, the effect may not be easily recognized.

The relation of Red, Green and Blue to each other is typically represented in the form of a circle. Adjustment of
Chroma Level (color saturation) is to adjust the amplitude of chrominance signal at each point without changing thephase.
Adjustment of Chroma Phase (hue) is to rotate the whole circle to some degree.

When the White Balance position (WHITE BAL) switch is at the <B> or <A> position, this adjustment is enabled.
Example of video effects created by intentionally changed White Balance:

Scene like “early morning” acquired by increase of blue

5. Enhancing the level of expression for dark areas(Master Ped, RBG Black Control)
5-1. Pedestal (Master Pedestal) adjustment
Regarding the video signal, the reference of luminance signal is Black, which is called Master Pedestal. Adjusting thelower limit of this pedestal level allows not only the level of black floating but also the brightness balance of a whole
picture to be set.
What is called “sharper” or “softer look” is largely related to the adjustments of outline and gradation.

Slope for darker area is steep.

Contrast is reduced.

MASTER PED : -200
By decreasing the Master Pedestal level, the picture
becomes sharper with its contrast enhanced.

MASTER PED : +16
This is normal setting (factory default).

MASTER PED :+200
Increasing the Master Pedestal level can produce a
misty effect, especially around darker areas.

5-2. Technical description : About Pedestal
Master Pedestal (or Master Black, etc.) is for the adjustment of black level as the reference of a picture. Thisadjustment has a significant influence, so it is ideal to check the picture using the waveform monitor or higher definition
TV monitor.
