GAMMA/VISIBILITY
ENHANCER Menu
The GAMMA/VISIBILITY ENHANCER menu is used
to adjust GAMMA correction and VISIBILITY
ENHANCER features.
GAMMA
SELECT
You can choose the type of basic curve for GAMMA
correction.
STD: Standard setting (same as the MOVIE setting on
the camera).
STRAIGHT: This selects a straight GAMMA curve.
MOVIE: Use standard gamma curve for movies.
STILL: Use gamma curve for the tone of a still image.
CINE1: Softens the contrast in darker regions and
emphasizes gradation changes in lighter regions,
producing a subdued tone overall.
CINE2: Similar to [CINE1] but optimized for editing
with up to 100% video signal.
CINE3: Stronger contrast between dark and light
regions and greater emphasis on black gradation
changes (compared to [CINE1] and [CINE2]).
CINE4: Stronger contrast than [CINE3] in darker
regions. Compared to the standard curve, has less
contrast in darker regions and more contrast in
lighter regions.
ITU709: Gamma curve equivalent to ITU-709.
PATTERN: You can choose a gamma curve from 512
patterns stored in the camera. You can specify the
pattern out of 512 patterns using PATTERN and
PATTERN FINE. PATTERN defines the upper
two digits of the pattern, and PATTERN FINE
defines the last digit.
PATTERN: Choose a value from 0 to 51. This
can be chosen when SELECT is PATTERN.
PATTERN FINE: Choose a value from 0 to 9.
When PATTERN is 0, 0 cannot be chosen for
PATTERN FINE. When PATTERN is 51, a
value larger than 2 cannot be chosen for
PATTERN FINE. This can be chosen when
SELECT is PATTERN.
OFFSET: You can choose the offset of the output level
of gamma curves.
Choose a value from –64 to 0 to +64.
LEVEL: You can adjust the correction level of the
GAMMA curve. Choose a value from –7 to 0 to
+7.
BLACK GAMMA: You can adjust the black gamma
level to recreate gradation in the dark areas of the
picture or to suppress noise with black-out.
Choose a value from –7 to 0 to +7.
BLACK GAMMA RANGE: You can adjust the
brightness range for which BLACK GAMMA
becomes effective. Choose from LOW,
MIDDLE, and HIGH. The range becomes small
when LOW is chosen, and it becomes large when
HIGH is chosen.
BLACK LEVEL: You can adjust the master BLACK
LEVEL. Choose a value from –48 to 0 to +48.
VISIBILITY ENHANCER
SETTING
When this is turned ON, gradation correction is
adaptively performed according to the scene being shot.
EFFECT
You can adjust the brightness of the shadows on the
screen. Choose a value from –3 to 0 to +3.
