Abstract

The invention relates to a super-resolution image processing method and device; the image processing method comprises the following steps: amplifying an input image in n-time multiplying power according to an amplification algorithm so as to form a first image; reducing and sampling input image in the n-time multiplying power so as to form a second image; amplifying the second image in n-time multiplying power according to the amplification algorithm so as to form a third image; using the input image to subtract the third image so as to form a first difference image; amplifying the first difference image in n-time multiplying power according to the amplification algorithm so as to form a second difference image; and stacking the first image and the second difference image so as to form an output image.

Description

technical field [0001] The present invention relates to an image processing method and its device, and in particular to a super-resolution (super-resolution) image processing method and its device. Background technique [0002] Display devices have been improving day by day in recent years. Whether it is mobile phones, computers or TVs, the screen size is getting larger and larger, and because of the development of network technology, the demand for viewing images is also increasing. Since the amount of general image data is not small, the calculation amount caused by enlarging the image will also increase, and the accompanying processing time will increase relatively. [0003] Currently common image magnification technologies can be divided into two categories, one is the technology category based on the database, and the other is the technology category based on the interpolation method. Database-based technology categories usually need to collect a large number of low-re...
