Abstract

An image enhancement method and an image processing apparatus thereof are provided. The image enhancement method is adapted to the image processing apparatus and includes the following steps. An input image is obtained, wherein the input image has a plurality of intensity components. The input image is corrected according to a gamma curve. The sharpness of the corrected input image is enhanced based on an edge detection operator and a weight value. An output image suitable for a display panel is obtained based on the enhanced input image. The image enhancement method provided by the invention can enahnce the sharpness of the image to realize a defogging effect, and thus can improve the display quality of the display panel.

Description

technical field [0001] The present invention relates to an image processing technology, and more specifically, to an image enhancement method and an image processing device for dehazing an image. Background technique [0002] In modern society, various types of display panels, such as Liquid Crystal (LC) display panels, Light Emitting Diode (Light Emitting Diode) display panels, have been proposed and widely used in electronic products for displaying images or videos. -Emitting Diode (LED for short) display panel and Organic Light-Emitting Diode (OLED for short) display panel. However, the development of display technology never stops, and the display industry is further developed towards transparent displays. [0003] Transparent display panels can be constructed using polymer dispersed liquid crystal (PDLC) technology. Such a transparent display panel can be electrically switched between a scattering state and a transparent state, and the light scattering characteristics...
