Problems solved by technology

[0005] Since an image enlargement algorithm is used in the prior art to enlarge the image, and based on the above prior art, since the gray value of the image pixel in the low-frequency component of the image changes little, no matter whether a simple algorithm or a complex algorithm is used for the image The amplification effect of the low-frequency component is equivalent; and a more complex algorithm for the high-frequency component of the image can achieve a good image effect, but both the high-frequency component and the low-frequency component of the image will increase when the complex algorithm is used for amplification. Extra calculation, so it is not possible to take into account both the calculation load of the enlargement process and the image quality after image enlargement

Abstract

The embodiment of the invention provides an image magnification method, an image magnification device and a display device, and relates to the technical field of image processing. The method specifically includes the steps that the image magnification device obtains the high-frequency components and the low-frequency components of a source image; the image magnification device conducts pixel interpolation on the low-frequency components of the source image through the first interpolation algorithm so as to obtain low-frequency sub-images; the image magnification device conducts pixel interpolation on the high-frequency components of the source image through the second interpolation algorithm so as to obtain high-frequency sub-images; the image magnification device fuses the low-frequency sub-images and the high-frequency sub-images so as to obtain fusion result images, wherein the first interpolation algorithm and the second interpolation algorithm are different so that the quality of the magnified image can be ensured while the calculation amount is reduced. The image magnification method, the image magnification device and the display device are used for image magnification.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to an image enlarging method, an image enlarging device and a display device. Background technique [0002] The purpose of image magnification is to improve the resolution of the magnified image to meet people's visual requirements or practical application requirements. Image magnification has very important applications in high-definition television, medical images and other fields. [0003] The image contains high-frequency components and low-frequency components, wherein the high-frequency components are mainly distributed in the edge contour parts and detail parts of each subject in the image, and the low-frequency components are mainly distributed in the non-edge contour parts of each subject in the image. [0004] At present, the same algorithm is usually used to amplify the high-frequency and low-frequency components of the image. The interpolation algor...
