摘要
介绍了应用于AVS视频解码芯片的图像缩放(Scaling)模块。该模块依次通过垂直方向、水平方向进行图像像素重采样,再运用移位和加法运算达到了图像缩放效果。算法是硬件可实现的,图像缩放效果好,视觉感尚佳,硬件成本低。此方案已成功运用到AVS视频解码芯片项目中,实现了图像缩放的功能。
The paper introduces the image-scaling module and its implementation for AVS-video decoded chip. The module resamples the pixel through the vertical and the level direction in correct order, and apply to the shift and the addition to achieve the image-scaling. The algorithm is implemented, and can achieve fine image quality with lower hardware cost. This scheme has already been used in the AVS-video decoded chip project to realize the image-scaling function.
