EXTENDED BIT-RANGE IN HEIF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18486634 titled 'EXTENDED BIT-RANGE IN HEIF

    • Simplified Explanation:**

The patent application describes a method for improving image coding techniques for high-bit depth images by deriving separate lower-bit-depth main and extension images from a single high-bit-depth source image, encoding them separately, and then combining them at the decoder to reconstruct the original image.

    • Key Features and Innovation:**
  • Deriving separate lower-bit-depth main and extension images from a high-bit-depth source image.
  • Encoding the separate images as lower-bit-depth images.
  • Combining the separate main and extension images at the decoder to reconstruct the original image.
  • Use of lossless or lossy codecs for encoding.
  • Providing backward compatibility with legacy decoders.
    • Potential Applications:**

This technology can be applied in various fields such as digital photography, medical imaging, satellite imaging, and video compression.

    • Problems Solved:**

This technology addresses the challenge of efficiently encoding and decoding high-bit-depth images while maintaining image quality and compatibility with existing systems.

    • Benefits:**
  • Improved image coding efficiency.
  • Enhanced image quality preservation.
  • Backward compatibility with legacy systems.
  • Potential reduction in file sizes for storage and transmission.
    • Commercial Applications:**

Original Abstract Submitted

Improved image coding techniques for high-bit depth images includes deriving two or more separate lower-bit-depth main and extension images from one high-bit-depth source image, and then encoding them separately as lower-bit-depth images. At a decoder, the separate main and extension images are decoded, and then combined to create a single reconstructed source image. The improved techniques may use lossless or lossy codecs, and may provide some backward compatibility with legacy decoders.
