Abstract
A display system is configured to convert Full-High Definition (FHD) image content into Ultra-High Definition (UHD) image content. The display system includes an interface configured to receive image content comprising a first resolution, such as FHD. The display system also includes a display device configured to display image content at a second resolution, such as UHD, the second resolution greater than the first resolution. The display system further includes one or more processors configured to: convert the image content from the first resolution to the second resolution; recover a spatial frequency of the converted image content as a function of a relative edge growth rate measured from the converted image content and an offline-determined relationship between the relative edge growth rates of the converted first image and its corresponding ground truth image; and provide the converted image content with the recovered spatial frequency to the display device.
