The Designing Of Real-Time Reconstruction And VGA Display Controller Of High Resolution CFA Image

With the increase of video exhibit table image sensor resolution, the technology of real-time display movement image is becoming the kernel research task of product. At present, current solution is DSP+ASIC chip, DSP implements CFA interpolation algorithm, which reconstructs Bayer template CFA image to color image, ASIC chip upgrades the low frame frequency color image of DSP processed to the standard frame frequency of VGA display interface. This paper brings forward a design scheme, which uses FPGA substituting DSP+ASIC truss.This paper focuses on the three aspects below and achieves some results:(1) Hardware implementing of FPGA development platformThis paper adopts the XC2S300E-PQ208-6-C of Xilinx company as kernel device, chooses CMOS image sensor module OV9650 to be the CFA image import-source, regards two pieces of SDRAM as frame buffer memory, builds hardware development platform of FPGA.(2) Using VHDL language implements real-time bilinear interpolation algorithm...
