Title: The Innovative Contributions of Francois Cellier
Introduction
Francois Cellier is a notable inventor based in Rennes, France. He has made significant contributions to the field of image processing, particularly in the area of dynamic range reconstruction. With a total of 3 patents to his name, Cellier's work has advanced the technology used in visual media.
Latest Patents
Francois Cellier's latest patents include innovative systems and methods for tone mapping functions. One of his patents, titled "Saturation control for high-dynamic range reconstruction," provides a method for generating a tone mapping function that reduces the dynamic range of a first image to produce a second image. This process involves determining a luma signal and multiple chroma components, followed by performing a gamut color correction. Additionally, an adaptive function is generated by comparing the luma signal and at least one chroma component of both images.
Another significant patent is "Tone mapping adaptation for saturation control." This invention outlines a method for applying an initial tone mapping function on a first image to create a second image with a different dynamic range. The method includes applying a second tone mapping function to the second image when it contains saturated portions, effectively lowering luminance by a specified fraction. The overall luminance of the second image is also assessed, and a fine-tuning filter is applied when certain areas are darker than a predetermined amount.
