ABSTRACT:
The present invention provides a method and apparatus of adaptive de-interlacing of dynamic image, configured for calculating characteristic values of each line segment of current frame in sequence according to width of line segment. Next, calculating the difference between characteristic values of each line segment of current frame and characteristic values of each corresponding line segment of reference frame in sequence to acquire an image shift value of line segment. And next, comparing the image shift value of line segment with a threshold to determine a de-interlacing algorithm for executing the de-interlacing and constituting a high-resolution dynamic image. At the same time, storing characteristic values of each line segment of current frame for being the characteristic values of each corresponding line segment of the former frame when calculating the image shift value of line segment of the next frame. By adjusting width of line segment and a threshold, it can control which kind of de-interlacing for using and information amount of each de-interlacing process to acquire good image quality of dynamic image and elasticity of operation.
