Abstract

An image enlargement and optimization method and an image processing device using the method are provided. The image processing device mainly includes an image signal acquisition module, a memory, and an image signal processing module to perform the following image amplification and optimization methods: the image signal acquisition module acquires a unit array and a peripheral array from the image signal, the unit array includes a plurality of pixels, the The peripheral array includes a plurality of auxiliary pixels, wherein each pixel and each auxiliary pixel have image parameters respectively; the memory stores a plurality of preset continuous edges; the image signal processing module compares the image parameters of each pixel and each auxiliary pixel, and according to each image parameter The comparison result classifies each pixel and each auxiliary pixel into one of the first pixel point group and the second pixel point group. The invention can keep the sharp and smooth edge of the enlarged image, and can also improve the problem of blurred edge of the image.

Description

technical field [0001] The invention relates to an image enlargement and optimization method and an image processing device using the method. Background technique [0002] In the process of image processing, it is often necessary to increase the resolution of the image before enlarging the image. For example, due to the progress in display technology and technology in recent years, new liquid crystal or plasma TVs can break through the limitations of traditional vacuum tube (CRT) displays, and can obtain larger display areas at a more reasonable cost. High picture resolution. At the same time, the source of the image may only contain lower resolution information. One of the most frequently proposed examples is: when it is necessary to play traditional NTSC (National Television System Committee, National Television System Committee) standard image signals on HDTV (High Definition Television), due to the standard image format resolution of HDTV Up to 1920x1080 pixels, while...
