Variable Gamma Curve
(SSC-DC590 series/SSC-DC570 series/SSC-DC80 series)
Users can choose from four preset gamma curves,
including two unique gamma curves, so that the brightness
levels of captured images are controlled precisely. Images
in their entirety can be displayed clearly and accurately.
(i.e. not too bright and not too dark). (See Fig. 4)
One of the two unique gamma curves reduces the
brightness level of the dark portions of the image, while
increasing the brightness level of the bright portions of the
image, which is ideal for scenes that have very little
contrast (SCENE2; See Fig. 5).
The other unique gamma curve increases the brightness
level of the dark portions of the image, while reducing the
brightness level of the bright portions of the image
(SCENE3; See Fig. 5).
By selecting a gamma curve that is appropriate for a given
scene, captured images can be reproduced clearly and
sharply.
