中文摘要：
针对数码相机、手机等移动设备的特点,提出一种基于高分辨率传感器的无损电子变焦模型,该模型同时克服了光学变焦模型和传统电子变焦模型的缺陷,输出图像可以达到光学变焦的效果.针对图像在缩放过程中的混叠现象,提出一种基于FPGA的抗混叠滤波和双线性插值相结合的图像缩放算法.通过MATLAB仿真表明,该算法得到的图像质量较高,硬件实现简单.
英文摘要：
First of all, according to the characteristics of digital cameras, mobile phones and other mobile devices, a nondestructive electronic zoom model based on high resolution sensors is proposed. The model overcomes the defects of optical zoom model and the traditional digital zoom model at the same time and the output image can achieve the effect of the optical zoom .Secondly a kind of image scaling algorithm based on FPGA combining anti-aliasing filter and bilinear interpolation is put forward to solve the aliasing phenomenon in the process of scaling the image. By Matlab simulation, the image quality of this algorithm is superior and the hardware implementation is simple.
