摘要： Different distances of two or more objects in a scene being captured in a video conference are determined based on applying a face model to a detected face within a digitally-acquired image. At least one portion of the scene other than the face is identified as comprising a background object that is a different distance from the video camera component than the face. The technique involves blurring or otherwise rendering unclear the background object.

摘要： Different distances of two or more objects in a scene being captured in a video conference are determined by determining a sharpest of two or more color channels and calculating distances based on the determining of the sharpest of the two or more color channels. At least one of the objects is identified as a foreground object or a background object, or one or more of each, based on the determining of the different distances. The technique involves blurring or otherwise rendering unclear at least one background object or one or more portions of the scene other than the at least one foreground object, or combinations thereof, also based on the determining of distances.

摘要： Different distances of two or more objects in a scene being captured in a video conference are determined using an auto-focus sweep of the scene. A depth map of the scene is generated based on the auto-focus sweep. At least one of the objects is identified as a foreground object or a background object, or one or more of each, based on the determining of the different distances. The technique involves blurring or otherwise rendering unclear at least one background object or one or more portions of the scene other than the at least one foreground object, or combinations thereof, also based on the determining of distances.

摘要： A chromatic noise reduction method is provided for removing chromatic noise from the pixels of a mosaic image. In one implementation, an actual chroma value and a de-noised chroma value are derived for the central pixel of a matrix of pixels. Based at least in part upon these chroma values, a final chroma value is derived for the central pixel. The final chroma value is then used, along with the actual luminance of the central pixel, to derive a final de-noised pixel value for the central pixel. By de-noising the central pixel based on its chroma (which takes into account more than one color) rather than on just the color channel of the central pixel, this method allows the central pixel to be de-noised in a more color-coordinated fashion. As a result, improved chromatic noise reduction is achieved.
摘要翻译：提供了一种用于从马赛克图像的像素中去除彩色噪声的彩色降噪方法。在一个实现中，针对像素矩阵的中心像素导出实际色度值和去噪色度值。至少部分地基于这些色度值，为中心像素导出最终的色度值。然后使用最终色度值以及中心像素的实际亮度来导出中心像素的最终去噪像素值。通过基于其色度（其考虑多于一种颜色）而不是仅在中心像素的颜色通道上去除中心像素，该方法允许中心像素在更加颜色协调中被去噪声时尚。结果，实现了改善的色噪声降低。

摘要： A 9 pixel-by-9 pixel working window slides over an input Bayer image. For each such window, a demosaicing operation is performed. For each such window, corrective processing is performed relative to that window to produce relative differences for that window. For each such window for which relative differences have been produced, those relative differences are regulated. For each window, a maximum is found for that window's regulated relative differences; in one embodiment of the invention, this maximum is used to select which channel is sharp. For each window, the colors in that window are corrected based on the relative difference-based maximum found for that window. For each window, edge oversharpening is softened in order to avoid artifacts in the output image. The result is an output image in which axial chromatic aberrations have been corrected.
