摘　　要：针对传统图像缩放算法的不足,本文提出一种边缘检测和双线性插值结合的方案,用以实现图像缩放的功能。借助FPGA并行高速处理的优势,搭建各功能模块,最后通过仿真工具和板级验证,结果表明该设计能够有较理想的图像放大效果。Aim at the shortcomings of the traditional image scaling algorithm, this paper proposes that edge detection, combined with the bilinear algorithm is used to realize the function of image scaling. Take advantage of the FPGA parallel and high-speed processing, build each function module and verify by simulation tools and board-level. Results show that the design can have ideal image scaling effect.
