Patent Searching and Data


Title:
IMAGE PROCESSING METHOD AND IMAGE RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/193333
Kind Code:
A1
Abstract:
The present invention provides an image processing method for generating high-resolution image data from low-resolution image data, and an image reception device which operates using said image processing method. Specifically provided is an image processing method for generating high-resolution image data from low-resolution image data, wherein: a plurality of items of first image data are generated by dividing the low-resolution image data; one of two adjacent items from among the plurality of items of first image data is set as second image data and the other is set as third image data; fourth image data is generated by supplementing pixel data around the second image data; said pixel data includes a portion of the third image data; a convolutional neural network using the fourth image data as an input is applied; the convolutional neural network outputs fifth image data; and high-resolution image data is generated by combining a plurality of items of fifth image data. Also provided is an image reception device which operates using said image processing method.
