Sharpness: Sharpness can be defined as edge contrast, that
is, the contrast along edges in a photo. When we increase
sharpness, we increase the contrast only along/near edges in
the photo while leaving smooth areas of the image alone.
Color Gain: Color gain means saturation, it is similar to
contrast, however instead of increasing the separation between
shadows and highlights, it increases the separation between
colors.
DNR (Digital Noise Reduction): DNR is a technique of
removing image noise from a video signal by applying a digital
comb filter. It reduces the noise that can be found in low light
images and makes images clearer. This type of filter is
sometimes confused by motion, resulting in blur trails.
Video Format: PAL and NTSC, its NTSC in USA.
D-WDR: Digital WDR (D-WDR) is a software-based technique
that optimizes image quality by adjusting the gamma (γ) value
to enhance dark areas.
