Abstract

The invention discloses an image amplifying and optimizing method and image processing device through the method, wherein the image processing device contains image signal picking mode, memory and image signal processing mode; the image amplifying and optimizing method comprises the following steps: the image signal picking mode consists of image signal picking unit array and external array, wherein the unit array contain multiple pixels; the external array contains multiple subsidiary pixels; each pixel and each subsidiary pixel possess image parameter; the memory stores multiple preset continuous rim; the image signal processing mode compares the image parameter of each pixel and each subsidiary pixel, which classifies each pixel and each subsidiary pixel in one of first pixel point group and second pixel point group. The invention can keep sharp and fluent rim after amplifying the image, which can improve the fuzzy problem for image rim.

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 1920 × 1080 pixels, whi...
