IMAGE UP-SAMPLING WITH RELATIVE EDGE GROWTH RATE PRIORS
First Claim
1. An apparatus comprising:
- an interface configured to receive image content comprising a first resolution;
a display device configured to display image content at a second resolution, the second resolution greater than the first resolution; and
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 an associated reference value; and
provide the converted image content with the recovered spatial frequency to the display device.

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.

8. A method for converting image content, the method comprising:
-
converting a first image from a first resolution to a second resolution that is greater than the first resolution; recovering spatial frequency of the converted first image as a function of a relative edge growth rate measured from the converted first image and an offline-determined relationship between the relative edge growth rates of the converted first image and an associated reference value; and providing the converted first image with the recovered spatial frequency for display on a display device. - View Dependent Claims (9, 10, 11, 12, 13)

14. A non-transitory computer readable medium embodying a computer program, the computer program comprising computer readable program code that, when executed by a processor, causes the processor to:
-
convert a first image from a first resolution to a second resolution, the second resolution is greater than the first resolution; recover a spatial frequency of the converted first image as a function of a relative edge growth rate measured from the converted first image and an offline-determined relationship between the relative edge growth rates of the converted first image and an associated reference value; and provide the converted first image with the recovered spatial frequency for display on a display device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
