Abstract:

This system presents a fully pipelined color demosaicking design. To improve the quality of reconstructed images, a linear deviation compensation scheme was created to increase the correlation between the interpolated and neighboring pixels. Furthermore, immediately  interpolated green color  pixels  are  first  to  be  used  in  hardware-oriented  color demosaicking algorithms, which efficiently promoted the quality of the reconstructed image. A  boundary detector  and  boundary mirror  machine  were  added  to  improve  the  quality  of  pixels located in boundaries. In addition, a hardware sharing technique was used to reduce the hardware costs of three interpolators. Finally these are implemented and get the simulated result is compared to the previous architecture. The code are simulated and power, area, cost are taken using Xilinx 14.2 software and MATLAB. Compared with the previous low complexity designs, this work has the benefits in terms of low cost, low power consumption, and high performance.
