Abstract
A method for adaptively selecting filters to interpolate video data is provided. In the present method, when receiving video data encoded by a 4:2:2 sampling format, a plurality of filters having different weights are adaptively selected to convert the color components in the video data to a 4:4:4 sampling format based on the differences of luminance and color components among a target pixel and neighboring pixels thereof. Accordingly, the blurs occurred in an area with large color variation can be removed or reduced, such that the interpolated color components can be accepted by human eyes more easily.
