3-7. DRS: Useful for shooting the scene with large contrast between bright and dark areas
By starting up DRS (Dynamic Range Stretcher) function, the Gamma curve and Knee Slope are estimated according
to the signal level of each pixel and adjusted in real time. This allows both dark and bright areas to maintain the high
level of gradation expression and can minimize not only crushed blacks and blown-out highlights but also hue
compression.
DRS: OFF
DRS: ON
DRS EFFECT DEPTH : 3
Setting and Adjustment items for DRS: Main Menu [SCENE FILE]
(Factory default settings underlined)
[DRS］ OFF / ON
Enables / disables the Dynamic Range Stretcher function.
[DRS EFFECT DEPTH］ 1 / 2 / 3
Sets the compression level of high-brightness areas by Dynamic Range Stretcher function.
Compressing the video signal level of high-brightness area, which is so bright that it would be represented as
blown-out highlights in normal recording, enables the Dynamic Range to be expanded. A larger setting value has
more effect of DRS (compression level of high-brightness area) to make the Dynamic Range wider in appearance.
However, if this level is higher, the noise on dark areas may also be intensified. In addition, depending on the scene,
its picture may look unnatural. So it needs to be checked every time this adjustment is made. Also, when there is
an extremely dark or bright area, or when the brightness is not enough, the effect may not be easily recognized.
