==Tone Mapping for Preserving Contrast of Fine Features in an Image - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240078648 titled 'Tone Mapping for Preserving Contrast of Fine Features in an Image

==Simplified Explanation==

The patent application is focused on tone mapping systems and methods that preserve the contrast of fine features in an image while avoiding brightening monotonic regions. The image processing circuitry includes hardware for determining pixel statistics, generating a tone mapping to adjust color values, and applying the tone mapping to the low frequency component of the image to preserve fine details' contrast. Additionally, the circuitry can adjust the tone mapping based on variance bins in a pixel value histogram to prevent brightening monotonic regions.

* Hardware for determining pixel statistics
* Generation of a tone mapping to adjust color values
* Application of tone mapping to low frequency component to preserve fine details' contrast
* Adjustment of tone mapping based on variance bins in pixel value histogram to prevent brightening monotonic regions

== Potential Applications ==
The technology can be applied in various fields such as photography, video processing, medical imaging, and satellite imaging.

== Problems Solved ==
This technology addresses the issue of preserving fine details' contrast in images while avoiding brightening monotonic regions, leading to more visually appealing and accurate representations.

== Benefits ==
The benefits of this technology include improved image quality, enhanced visual appeal, accurate representation of fine details, and better overall image processing results.

== Potential Commercial Applications ==
Potential commercial applications of this technology include camera systems, image editing software, medical imaging devices, satellite imaging systems, and video processing tools.

== Possible Prior Art ==
One possible prior art in this field is the use of histogram equalization techniques in image processing to enhance contrast and brightness. However, the specific method of adjusting tone mapping based on variance bins to preserve contrast and avoid brightening monotonic regions may be a novel aspect of this patent application.

=== What are the specific hardware components used in the image processing circuitry?
The specific hardware components used in the image processing circuitry include processors, memory modules, and specialized image processing units.

=== How does adjusting the tone mapping based on variance bins in a histogram improve image quality?
Adjusting the tone mapping based on variance bins helps in preserving the contrast of fine details by preventing over-brightening of monotonic regions, resulting in a more balanced and visually appealing image output.


==Original Abstract Submitted==

this disclosure is directed towards tone mapping systems and methods that preserve contrast of fine features of an image and avoid brightening monotonic regions of the image. to preserve contrast and avoiding brightening of the monotonic regions, an image processing circuitry may include hardware that enables determining pixel statistics of an image, generating a tone mapping that is configured to adjust the color values of pixels in the image, and applying the tone mapping to at least the low frequency component of the image to produce an output image where the contrast of the fine details is preserved. in addition, the image processing circuitry may include hardware that enables adjusting the tone mapping based on variance bins in a histogram of pixel values and applying the adjusted tone mapping to produce an output image where the monotonic regions are not brightened.
