Adjusting Image Quality; Detail Function; Skin Tone Function - Panasonic AJ-PX270 Operating Instructions Manual

Adjusting image quality

The image quality of the video to be recorded can be set in the main menu → [SCENE FILE]. To change "Advanced settings", measuring equipment
such as vector scope is necessary.

Detail function

This function thickens or weakens the outlines of images. It effectively softens or sharpens images, but in some cases, the whole image may become
rough due to emphasized noise and edges. To avoid such problems, it is necessary not to add this effect on parts where emphasizing is not needed and
keep the details of the parts.
r General settings
[MASTER DTL]: Sets the level of the detail effect of the whole part.
[DTL CORING]: Sets the level of signal (including noise) not to activate the detail effect.
r Advanced settings
Set in the main menu → [SCENE FILE] → [DETAIL SETTING].
[DETAIL]: Sets [ON]/[OFF] of the detail function.
[V.DTL LEVEL]: Sets the intensity of the detail level in the vertical direction.
[H.DTL FREQ.]: Sets the thickness of the detail level in the horizontal direction.
[V. DTL FREQ.]: Sets the thickness of the detail level in the vertical direction.
[LEVEL DEPEND.]: When the detail of luminosity signal is emphasized, details in the darker parts are compressed. Details of bright areas are also
compressed more when the value set for [LEVEL DEPEND.] is larger.
[KNEE APE LVL]: Sets the detail level of high luminosity areas (high-brightness areas).
[DTL GAIN(+)]: Sets the detail level of + direction (to make brighter).
[DTL GAIN(−)]: Sets the detail level of − direction (to make darker).

Skin tone function

This function makes human skin look smoother in images.
r General settings
[SKIN TONE DTL A]/[SKIN TONE DTL B]/[SKIN TONE DTL C]: Selects what kind of skin color where the skin tone detail function should work from
the three data [SKIN TONE DTL A]/[SKIN TONE DTL B]/[SKIN TONE DTL C]. [SKIN TONE DTL A]/[SKIN TONE DTL B]/[SKIN TONE DTL C] can be set
alone or in combination.
[SKIN TONE ZEBRA]: When [SKIN TONE DTL A]/[SKIN TONE DTL B]/[SKIN TONE DTL C] are enabled, displays the zebra pattern in the selected skin
color field. The zebra pattern displays the area selected in [SKIN TONE DTL SETTING].
r Advanced settings
Configure the settings in the main menu → [SCENE FILE] → [SKIN TONE DTL SETTING].
[DETECT TABLE]: Selects the skin color table of the object on which the skin tone table is applied.
[SKIN TONE GET]: Acquires the color information of [A], [B], or [C] selected in [DETECT TABLE] from the area around the center marker. By executing
this menu, [I CENTER] to [Q PHASE] data are acquired automatically.
[SKIN DTL EFFECT]: Sets the effect level of the skin tone detail.
f The color composition of video signal (R/G/B) can be converted to color difference signal (R-Y/B-Y) as in (Fig. 1). Within those ranges, set the area on
which the following skin tone is applied, using the axis across red and cyan (I axis) and the axis across green and magenta (Q axis).
[I CENTER]: Sets the center position on the I axis (the area where the skin tone applied).
[I WIDTH]: Sets the area width where the skin tone is applied, along the I axis with [I CENTER] in the center.
[Q WIDTH]: Sets the area width where the skin tone is applied, along the Q axis with [I CENTER] in the center.
[Q PHASE]: Sets the phase where the skin tone is applied, with the Q axis being the reference.
