Chapter 4 Video Recording and Color Grading — Image quality adjustment
[DETAIL]
This function thickens or weakens the outlines of images.
It can have soft representation or sharp representation, but it can also have an effect to roughen the entire video by enhancing the noise or edge.
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.
The [DETAIL] function is disabled when [MAIN CODEC] is set to [AVC-Intra4K-LT]/[AVC-Intra2K-LT]/[AVC-Intra-LT].
1
Select [ON] in [MENU] → [SCENE FILE SETTINGS] → [DETAIL] → [SW].
2
Set the level with [CORING]/[MASTER LEVEL]/[FREQUENCY].
f
[CORING]:
Sets the level of signal (including noise) that does not activate the detail effect.
f
[MASTER LEVEL]:
Sets the level of the detail effect of the whole part.
f
[FREQUENCY]:
Sets the thickness of the detail entirely.
[SKIN DETAIL]
This function makes human skin look smoother in images.
The [SKIN DETAIL] is disabled when [MAIN CODEC] is set to [AVC-Intra4K-LT]/[AVC-Intra2K-LT]/[AVC-Intra-LT].
1
Select [ON] in [MENU] → [SCENE FILE SETTINGS] → [SKIN DETAIL] → [SW].
2
Set with [TABLE SELECT]/[ZEBRA SW]/[DETECT TABLE]/[GET]/[EFECT LEVEL].
f
[TABLE SELECT]:
Selects from the 3 table data of [A], [B], or [C] to determine which skin tone to operate the skin tone detail function.
[A], [B], and [C] can be set individually or in combination.
f
[ZEBRA SW]:
Sets whether to superimpose the zebra signal to the color by which the skin tone detail is applied.
f
[DETECT TABLE]:
Selects the table to set from the 3 table data of [A], [B], or [C].
f
[GET]:
Obtains the color information of [A], [B], or [C] selected in [DETECT TABLE] from near the center marker.
Data for [I CENTER] to [Q PHASE] is automatically acquired when executed.
f
[EFECT LEVEL]:
Sets the effect level of the skin tone detail for [A], [B], or [C] selected in [DETECT TABLE].

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 this, use the axis in the red-cyan color phase (I axis) and axis in the green-magenta color phase (Q axis) to set the area to apply the skin tone
against the [A], [B], or [C] table selected in [DETECT TABLE].
f
[- I CENTER]:
Sets the center position of the upper I axis (setting the area that applies the skin tone).
f
[- I WIDTH]:
Sets the width of the area that applies the skin tone of the upper I axis that focus on [I CENTER].
f
[- Q WIDTH]:
Sets the width of the area that applies the skin tone of the upper Q axis that focus on [I CENTER].
f
[- Q PHASE]:
Sets the phase of the area that applies the skin tone regarding to the Q axis.
