3-5. 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-PX230 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 used in 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.
