Patent number: 8339512Abstract: 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.Type: GrantFiled: March 5, 2009Date of Patent: December 25, 2012Assignees: Sony Corporation, Sony Electronics Inc.Inventor: Takaaki Ota

Patent number: 8325279Abstract: The invention relates to a method, device and computer-program product for suppression of undesired temporal variations, notably flicker, in a sequence of video frames. Histogram-based and similar approaches generally do not remove all flicker. Features that are resolved only in portions of the flicker cycle will manifest themselves as residual flicker. This effect is near-universal in bright regions of a scene. The inventive solution is a mapping that aims to resolve in the output only those features that are resolved in all frames of the flicker cycle. Use of time-maximal quantile values may preserve non-resolution of such image features that are unresolved due to intermittent bright saturation. Thus, in one embodiment, a reduction of resolution is attained by means of a pixel-value mapping based on selecting, over a time window, maximal and minimal quantile values, with maximal values being used for bright spatial regions and minimal values for dark spatial regions.Type: GrantFiled: September 1, 2009Date of Patent: December 4, 2012Assignee: Google Inc.Inventors: Willem Bastiaan Kleijn, Bjoern Volcker
