Abstract

The invention discloses an image enhancement device and method. The method comprises the following steps: according to a predetermined amplification ratio, amplifying an image as a low-frequency portion of an amplification image; obtaining a high-frequency portion of the image; performing portioning on the low-frequency portion of the amplification image so as to match a pixel block of the image; by use of the pixel block of the image, establishing a corresponding relation between a pixel block of the low-frequency portion of the amplification image and a pixel block of the high-frequency portion; and superposing the pixel block of the high-frequency portion to the low-frequency portion of the amplification image so as to obtain an image with improved resolution. The method is simple and highly efficient, greatly reduces the computational complexity of image processing and can realize real-time conversion and watching of high-definition images.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image enhancement device and method. Background technique [0002] In the field of image processing, image enhancement technology is a very important research direction. Image enhancement technology mainly focuses on making the original unclear image clear or enhancing certain features of interest and suppressing features of no concern, so as to achieve the purpose of improving image quality, enriching the amount of information, and enhancing image interpretation and recognition effects. [0003] Existing techniques for increasing image resolution can be divided into two categories, one is based on multiple low-resolution images, correcting the images, and then using interpolation, reconstruction or learning to obtain a high-resolution image, The effect of this kind of method largely depends on the motion parameters between the two images, and the computational complex...
