  • Method of performing an image-adaptive tone mapping and display device employing the same
    Patent number: 10984698
    Abstract: A method of performing image-adaptive tone mapping includes: determining a tone mapping curve based on a data signal corresponding to an image frame to be displayed on a display panel; determining whether a scene-change occurs between the image frame and a previous image frame by comparing the data signal with a previous data signal corresponding to the previous image frame; generating, in response to a determination that the scene-change does not occur, a final tone mapping curve based on the tone mapping curve and a previous tone mapping curve, which is applied to the previous image frame; determining, in response to a determination that the scene change occurs, the tone mapping curve as the final tone mapping curve; and performing a tone mapping by applying the final tone mapping curve to the image frame.

  • Method of performing an image-adaptive tone mapping and display device employing the same
    Patent number: 10664959
    Abstract: A method of performing an image-adaptive tone-mapping for a display device including performing a first tone-mapping on an image frame by applying a first tone-mapping function to respective non-target display blocks, and performing a second tone-mapping on the image frame by applying a second tone-mapping function obtained by applying a local weighted value to the first tone-mapping function to respective target display blocks.
