The detail and clarity of high-definition video content may be enhanced by a display device or client-side device before being displayed. In certain embodiments, the high-definition video image frames may be upsampled by scaling the image's resolution. The now-upsampled HD video image frames may then be low pass filtered so as to concentrate the image's energy distribution into a tighter range of frequencies. The filtered HD video image frames may then be sub-sampled back down, such as to the original HD image's frame resolution, or other HD-level resolution, without compromising image detail. In this fashion, the clarity and detail level in video content, even though already considered of a high-definition quality, may be further improved. |
