Title:
CREATING DETAILS IN AN IMAGE WITH FREQUENCY LIFTING
Document Type and Number:
WIPO Patent Application WO/2014/142630
Kind Code:
A1
Abstract:
One or more embodiments relate generally to ultra-high definition displays, and in particular, to creating details in lower resolution images with frequency lifting for display on a UD display or device. A method comprises receiving input image information, using a processor device for determining enhancement information based on frequency characteristics of the input image information, and mixing the enhancement information with the input image information to generate an enhanced image.
