Title:
IMAGE PROCESSING METHOD, IMAGE PROCESSING DEVICE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/218404
Kind Code:
A1
Abstract:
An image processing method, an image processing device, and a display device, relating to the technical field of image processing. In the method, interpolation processing is performed on an image to be processed, so as to obtain an interpolated image, and initial pixel values of respective interpolated pixels in the interpolated image are then updated, so as to reduce, for each interpolated pixel, the difference between a second-order derivative of the updated pixel value of the interpolated pixel and a second-order derivative of a pixel value of a target original pixel in the interpolated image, thereby reducing artifacts generated in the interpolated image, improving image continuity in the neighboring region of the interpolated pixels in the interpolated image, and improving the quality of the finally obtained processed image.
