SMART HIGH DYNAMIC RANGE IMAGE CLAMPING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17824794 titled 'SMART HIGH DYNAMIC RANGE IMAGE CLAMPING

Simplified Explanation

The patent application describes a method for generating a High Dynamic Range (HDR) image.

  • Obtains two images, one with a lower exposure and the other with a higher exposure.
  • Sets pixels below a certain threshold in the lower exposure image to a minimum value and pixels above a certain threshold in the higher exposure image to a maximum value.
  • Retrieves compressed versions of both images with the adjusted pixel values.
  • Generates two decompressed images, one with the minimum value pixels and the other with the maximum value pixels.
  • Combines the decompressed images to generate an HDR image.


Original Abstract Submitted

Systems and techniques are provided for generating an HDR image. An example method can include obtaining a first image and a second image that has an exposure that is greater than an exposure of the first image; setting pixels of the first image that are below a minimum threshold to a minimum value and pixels of the second image that are above a maximum threshold to a maximum value; retrieving, from memory, a compressed version of the first image with the pixels set to the minimum value and a compressed version of the second image with the pixels set to the maximum value; generating a first decompressed image including the first image with the pixels set to the minimum value and a second decompressed image including the second image with the pixels set to the maximum value; and generating an HDR image based on the first and second decompressed images.
