    Chroma and Luma
    It is well known in the field of photography, video signal processing and digital imaging how chrominance and luminance of an image play very different roles when it comes to human perception.
    Generally, luminance defines details and contrast while chrominance can be seen as a low-contrast image representing only Hue and Saturation of colors - HSL color space.
    JPEG and MPEG algorithms use the YCbCr color space, which is based on chroma/luma separation. Since the chrominance of an image is low in contrast, it can be spatially down-sampled in order to achieve initial image/video compression.

    The CLARITY-24TM Improvement
    CLARITY-24™ fully exploits chroma and luma properties in digital imaging and video encoding, thus allowing for improved compression ratio while retaining most of the perceptive quality at a given bit-rate.
    By employing CLARITY-24™ digital videos and images can be reduced to up to 70% of their original size before applying any desired codec. CLARITY-24™ is especially suited and designed for mid/low bit-rate applications such as:
  • Video for VOIP applications.
  • Video Mobile, UMTS applications.
  • Satellite and cable TV digital broadcasting.
  • Texture compression for Videogames.
  • Image sequences and video for the Web.

    • Specifically, CLARITY-24TM allows for:
  • Compression ratio improvement up to 3:1 over compressed video.
  • Significant reduction in bandwidth requirements for video broadcasting.
  • Employment of any video codec or image compression algorithm.
  • Avoids DXTC artifacts in 3D applications and up to 6:1 compression ratio.
  • High-resolution texturing beyond graphic card's physical limits.
  • Extremely "light" algorithm.
  • Can be coupled with CLARITY-HDR™ and CLARITY-48™.
