Title
(EN) Method of using multiple resolutions to improve image quality and apparatus thereof
(ZH) 使用多分辨率改善图像质量的方法及装置
Abstract
(EN)
The invention provides a method of using multiple resolutions to improve image quality. The method comprises the following steps of receiving image data; according to first parameter information, dividing the image data into areas corresponding to different plural resolutions, wherein the resolutions correspond to different frequencies; through a single pass mode, using the different frequencies to render the areas and outputting rendered image data; and according to second parameter information, analyzing the rendered image data into final output image data possessing a first resolution.

(ZH)
本发明提出一种使用多分辨率改善图像质量的方法。上述方法包括以下步骤:接收一图像数据;根据一第一参数信息将上述图像数据分为对应至复数不同分辨率的区域,其中上述分辨率对应至不同频率;透过一单遍(single pass)方式以上述不同频率渲染上述区域,并输出一已渲染图像数据;以及根据一第二参数信息解析上述已渲染图像数据为具有一第一分辨率的一最终输出图像数据。
