数字图像缩放的原理与硬件实现
The principle and hardware implementation of digital image scaling
【摘要】 在对数字图像的缩放原理进行理论分析的基础上,给出了适合工程应用的简化缩放公式. 以数字自动印刷机为例,介绍了用硬件实现数字图像缩放的方法,并对数字图像经过缩放后产生的误差与失真进行了分析.
【Abstract】 The principle of digital image scaling is theoretically analysed at first. Based on that, the simplified formula of image scaling is proposed, which is more suitable to engineering applications. Then, taking the digital automatic printer as example, image scaling implemented by hardware is introduced in detail. At last, the errors and distortions produced in image scaling are analyzed.
