摘要： A system and method for performing Bayer reconstruction of images using a programmable graphics processing unit (GPU) are described herein. A Bayer filtered image in RAW format is uploaded to the GPU, unpacked, and reconstructed. Optionally, the reconstructed image may be transformed into any desired color space and/or displayed by a video card in which the GPU resides. The reconstruction is performed independently on each of the red, blue, and green image fields. The red and blue image fields are reconstructed using first and second interpolation passes in first and second orthogonal directions. Each reconstruction pass preferably employs a two-lobed Lanczos filter. The green image field is interpolated using a single interpolation pass in a direction diagonal to the first and second orthogonal directions, and preferably employs a box filter.

摘要： A system, apparatus, computer readable medium, and method for radially-dependent noise reduction in image capturing devices involving an edge-preserving blur window are disclosed. In one embodiment, the edge-preserving blur includes only those pixels in the blur window that are within a threshold value of the blur window's current center pixel in its blurring calculation. By creating a threshold function that varies radially from the center of the image sensor's light intensity falloff function, a more appropriate threshold value can be chosen for each pixel, allowing for more noise farther from the center of the image, and allowing for less noise closer to the center of the image. Light-product information taken from the image's metadata may be used to scale the threshold value parameters dynamically. This allows the method to perform the appropriate amount of processing depending on the lighting situation of the image that is currently being processed.

摘要： Disclosed are a system and method for computing a desktop picture. Instead of loading a file that contains the desktop image from memory, the present invention provides for a system and method for opening and retaining a procedural recipe and a small set of instructions that can be executed to compute a desktop picture. The desktop picture can be computed very quickly using a GPU (graphics processing unit), and can be made to move on demand. When a part of the desktop image is needed to composite, that part is computed using a fragment program on the GPU using the procedural recipe and a specially written fragment program into a temporary VRAM buffer. After it is computed and composited, the buffer containing the result of the fragment program may be discarded.

摘要： A system, apparatus, computer readable medium, and method for noise reduction in image capturing devices involving an edge-preserving blur window is disclosed. In one embodiment, the edge-preserving blur includes only those pixels in the blur window that are visually close to the blur window's current center pixel in its blurring calculation. Limiting the pixels considered in the blur to those that are visually close to the center pixel ensures that the image's colors are not blurred along color edges within the image. Light-product information taken from the image's metadata, for example, the camera sensor's gain level, may be used to adjust the blur filter parameters dynamically. This allows the method to perform the appropriate amount of processing depending on the lighting situation of the image that is currently being processed.

摘要： Increasing color saturation and contrast in images generally leads to more pleasing images; however, doing so uniformly to all colors in the image can make skin tones appear with an overly red tint. One embodiment of an improved method of skin tone aware color boosting identifies areas of the image which look like skin tones and areas that do not look like skin tones. A blurred “skin tone mask” can then be created over the image. One large boost operation and one small boost operation can be applied to the image. A final version of the image may then be created, applying the pixel values resulting from the small boosting operation to the skin tone regions and applying the pixel values resulting from the large boosting operation to the non-skin tone regions, using the blurred mask to provide a smooth transition between the skin tone and non-skin tone regions.
摘要翻译：增加图像中的色彩饱和度和对比度通常会导致更令人愉快的图像; 然而，对图像中的所有颜色均匀地进行，可以使皮肤色调出现过度的红色色调。一种改进的肤色感觉色彩增强方法的一个实施例识别看起来像皮肤色调的图像区域和看起来不像肤色的区域。然后可以在图像上创建一个模糊的肤色蒙版。可以对图像应用一个大的升压操作和一个小的升压操作。然后可以创建图像的最终版本，将由小增强操作产生的像素值应用于肤色区域，并且使用模糊掩码将来自大增强操作的像素值应用于非肤色区域提供肤色和非肤色区域之间的平滑过渡。
