MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517044707 A) filed by Interdigital Ce Patent Holdings Sas, Paris, on May 8, for 'method and device for generating a dimming map based on a lightweight deep network.'
Inventor(s) include Le Meur Olivier; Demarty Claire Helene; Blonde Laurent; Reinhard Erik; and Aumont Franck.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "A method and device allow to reduce the pixel values an input image by combining a dimming map to the input image. This results in reducing the energy consumption required to display the dimmed image while preserving as much as possible the quality of experience when displaying the dimmed image. The reduction of the pixel values can be done by either reducing the luminance and optionally the chrominance or reducing the color components of the image. The dimming map is generated by a lightweight deep learning network based on a small set of parameters and with a target pixel values reduction rate. The generated dimming map aims at preserving visual similarity and is explicitly conditioned to respect specific constraints. For example a smoothness constraint allows to the dimming map to be robust to downsampling. Two architectures and two training methods are proposed."
The patent application was internationally filed on Nov. 20, 2023, under International application No.PCT/EP2023/082360.
