    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.

    摘要： A forward interpolation approach is disclosed for enabling a second version of an image to be constructed from a first version of the image. According to one implementation, an input pixel from the first version of the image is forward mapped to the second version of the image to determine a set of candidate pixels that may be affected by the input pixel. Each candidate pixel is then backward mapped to the first version of the image to determine whether they are actually affected by the input pixel. For each candidate pixel that is actually affected by the input pixel, a pixel value is determined for that candidate pixel based at least in part upon the pixel value of the input pixel. By using this forward and backward mapping technique, forward interpolation can be implemented quickly and efficiently.

    摘要翻译： 公开了一种用于使得能够从图像的第一版本构建图像的第二版本的前向内插方法。 根据一个实现，来自图像的第一版本的输入像素被前向映射到图像的第二版本，以确定可能受输入像素影响的一组候选像素。 然后将每个候选像素反向映射到图像的第一版本，以确定它们是否实际上受到输入像素的影响。 对于实际上受输入像素影响的每个候选像素，至少部分地基于输入像素的像素值来为该候选像素确定像素值。 通过使用这种前向和后向映射技术，可以快速有效地实现前向插值。

    摘要： In accordance with an embodiment of the invention, an anisotropic denoising method is provided that removes sensor noise from a digital image while retaining edges, lines, and details in the image. In one embodiment, the method removes noise from a pixel of interest based on the detected type of image environment in which the pixel is situated. If the pixel is situated in an edge/line image environment, then denoising of the pixel is increased such that relatively stronger denoising of the pixel occurs along the edge or line feature. If the pixel is situated in a detail image environment, then denoising of the pixel is decreased such that relatively less denoising of the pixel occurs so as to preserve the details in the image. In one embodiment, detection of the type of image environment is accomplished by performing simple arithmetic operations using only pixels in a 9 pixel by 9 pixel matrix of pixels in which the pixel of interest is situated. As a result, improved image environment sensitive noise reduction is achieved that requires a relatively low gate count in hardware implementations.

    摘要翻译： 根据本发明的实施例，提供了一种各向异性去噪方法，其从数字图像中去除传感器噪声，同时保留图像中的边缘，线和细节。 在一个实施例中，该方法基于所检测到的像素所在的图像环境的类型来从感兴趣的像素中去除噪声。 如果像素位于边缘/线图像环境中，则增加像素的去噪，使得像素的相对较强的去噪沿边缘或线特征发生。 如果像素位于细节图像环境中，则减小像素的去噪，使得像素的去噪相对较少，以便保留图像中的细节。 在一个实施例中，通过仅使用感兴趣像素所在的像素的9像素×9像素矩阵中的像素执行简单的算术运算来实现对图像环境的类型的检测。 结果，实现了改进的图像环境敏感的降噪，其在硬件实现中需要较低的门计数。

    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： A lens system is provided that comprises an enhanced depth of field based on a uniform or near uniform relative illumination via a lens with a large distortion. The distortion can be corrected with image processing equipment. The lens system can comprise an aperture stop and a group of lens, wherein there can be about five lenses in the group of lenses.
