between dark and bright, making shadows darker and
highlights brighter. Decrease contrast and you bring the
shadows up and the highlights down to make them
closer to one another.
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.
3DNR (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.
