Algorithm of text image scaling based on LCD scaler

分析了文本型图像自身的特点及图像的缩放原理,推导出曲面拟合法的数学公式,模拟了不同算法作用于图像缩放的输出结果,并根据LiquidCrystalDisplay(LCD)定标器的模块划分将该算法用RTL级代码进行描述、仿真和综合,最后用FPGA实现,验证其逻辑功能.

After analyzing the characteristic of text images and the principle of image scaling, the formula of surface fitting were given and the output image simulated based on different algorithm. The arithmetic was described, simulated and synthetized with RTL behavior according to the specific module of Liquid Crystal Display (LCD) scaler. The verification fied programable gate array (FPGA) and testing of the scaler based on this scaling algorithm were presented.
