Abstract:

This paper proposes a de-interlacing algorithm based on motion detection.The theory is to divide the image into static part and motion part by the 4-field based horizontal motion detection and intra-field interpolation detection,and then the front-field value and intra-field interpolation are adopted for de-interlacing.The proposed algorithm is implemented by FPGA and the result is displayed on VGA.By observing the image,we can conclude that the proposed arithmetic can remove flaws like blur and zigzag effectively,contributing to a good effect.
