This paper presents a quality enhancement method to efficiently enhance the resolution of the scalable view window on touchable displays. Based on an optimized image interpolation algorithm, the image quality on the display systems can be enhanced. The image interpolation algorithm combines a 6-tap interpolation filter and a bilinear filter which can be effectively and efficiently optimized to reduce computational complexity. In addition, the cost-effective hardware architecture of the algorithm is also designed and implemented on an FPGA platform with a touchable display. The experimental results demonstrate the feasibility of the proposed method.
