MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517056847 A) filed by Interdigital Ce Patent Holdings, Sas, Paris, on June 13, for 'method and device for reducing display energy by using spatially alternating complementary colors.'
Inventor(s) include Blonde, Laurent; Demarty, Claire-Helene; Aumont, Franck; Le Meur, Olivier; and Reinhard, Erik.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "A method and device allow to reduce the energy or power consumption needed for rendering an image by replacing a pair of adjacent pixels of the image by pixels of spatially alternating complementary colors requiring less energy for display, in other words, by setting the colors of a pair of adjacent pixels of the image to a pair of spatially alternating complementary colors requiring less energy for display. Such solution is exploiting the spatial fusion characteristic of the human vision system that perceives complementary neighboring pixels as a single pixel. The spatially alternating complementary colors are selected to be more frugal than a single color in terms of power consumption required for rendering the color. This combination doubles the search space dimension for energy reduction from three to six. The technique used for replacing a pixel by adjacent pixels of spatially alternating complementary colors is performed either by pixel doubling, by pixel skipping or by pixel averaging. The association between a color and the corresponding spatially alternating complementary colors can be stored in a look-up table. These principles may be used on an image or a video comprising a succession of images."
The patent application was internationally filed on Dec. 12, 2023, under International application No.PCT/EP2023/085303.
