A1 camera technology eliminates false color artifacts (Moire) by utilising a special optical low pass filter and is able to resolve a horizontal resolution of 600 TV lines, by means of 12 Bit A/D serial signal processing coupled with image element enhancement technology. Additionally, the implementation of a 3 line processing algorithm to prevent noise under low illumination applications, directional adaptive filtering and adjustment of aperture gain by luminance level combine to provide a more vivid and clearer image.
• Motion Adaptive DNR
The A1 DNR (Digital Noise Reduction) function eliminates noise thus generating a distinct and clear image. A1 technology utilises both an adaptive 2D filter reducing noise in the brightness of the image and an adaptive 3D Filter reducing noise caused by movement. These filters are combined with DNIe technology which is applied to Samsung Electronics CCTV moniors. The result is that A1 camera series support Motion Adaptive DNR function that removes noise (Fixed Pattern, Random, etc.) and greatly reduces motion blur.
• Extended Dynamic Range
Under strongly backlight or high contrast scenes, cameras generally produce images which reproduce detail in the brighter area of the scene.(fig1) Consequently, detail is often lost in the darker areas of the scene. Samsung A1 cameras provide XDR technology to increase the level of visible detail in the dark areas, whilst maintaining image clarity and detail in the brighter portions of the image.
• Wide Dynamic Range
A1 camera series achieve WDR by using Dual Shutter [Long/Short] Algorithm for operating a Dual Scan CCD. WDR Block includes FMEI (Fusion of Multi-Exposure Images) and a contrast enhancer. The FMEI circuitry analyzes and mixes long and short exposure images to preserve the image detail from both bright and dark portions of the scene. The contrast enhancer sustains the effective contrast range and expands Dynamic Range up to 128x[NTSC] and 160x[PAL].
• Digital Image Stabilization
On A1 camera units, the shaking stabilization performance and accuracy have been improved compared to previous models, by using integer sub-pixel compensation technology. DIS uses the motion detection core for stabilizing the image shake from unwanted external vibration like oscillation and wind. Subsequently, by utilising the digital zoom core, the stabilized image can be produced from a shaking image by getting data which are interpolated as Cubic Spline Interpolation format.
