  • Patent number: 10580118
    Abstract: A display driver includes an interface circuit configured to receive an input image of a virtual reality (VR) experience from at least one of an application processor (AP) and a graphics processing unit (GPU); a coordinate correction circuit configured to generate corrected coordinates by adjusting input coordinates of pixels included in the input image; and an image generation circuit configured to generate an output image by distorting the input image using the corrected coordinates.
    Type: Grant

  • Patent number: 9754343
    Abstract: Image processing apparatus, an image processing system, and an image processing method. The image processing apparatus includes: an input image processing unit for outputting global information of sample data obtained by sampling first image data and dividing and outputting the first image data into an N (where N is a positive integer equal to or greater than 2) number of split image data; and a frame rate conversion unit including an N number of frame rate converters, wherein each of the N number of frame rate converters converts a frame rate of corresponding split image data among the N number of split image data synchronized with the global information and outputs the frame rate converted split image data as split display data, wherein the split display data is to be displayed on one of an N number of display regions.
