发明名称 Image processing method for reducing jaggy effect
摘要 An image processing method for reducing jaggy effect, which is applied in an image output device, is provided. Firstly, a continuous tone image is generated, and continuous tone pixels are defined according to a first addressing space. Then, a halftone image is generated. After that, the continuous tone image is low-pass filtered to generate a low-pass filtered image. Next, determine whether a position of the low-pass filtered image whose density is approximate to a pre-determined density. If so, generate a set of second addressing space co-ordinates of a key point corresponding to the position. Then, a moving vector corresponding to the key point is generated so as to regulate the position of a display point of the halftone pixel. Afterward, output the display point according to the position after regulation.
