摘要： Systems and methods for processing raw image data are provided. One example of such a system may include memory to store image data in raw format from a digital imaging device and an image signal processor to process the image data. The image signal processor may include data conversion logic and a raw image processing pipeline. The data conversion logic may convert the image data into a signed format to preserve negative noise from the digital imaging device. The raw image processing pipeline may at least partly process the image data in the signed format. The raw image processing pipeline may also include, among other things, black level compensation logic, fixed pattern noise reduction logic, temporal filtering logic, defective pixel correction logic, spatial noise filtering logic, lens shading correction logic, and highlight recovery logic.

摘要： At least certain embodiments described herein provide a continuous autofocus mechanism for an image capturing device. The continuous autofocus mechanism can perform an autofocus scan for a lens of the image capturing device and obtain focus scores associated with the autofocus scan. The continuous autofocus mechanism can determine an acceptable band of focus scores based on the obtained focus scores. Next, the continuous autofocus mechanism can determine whether a current focus score is within the acceptable band of focus scores. A refocus scan may be performed if the current focus score is outside of the acceptable band of focus scores.

摘要： The techniques disclosed herein use a compass, MEMS accelerometer, GPS module, and MEMS gyrometer to infer a frame of reference for a hand-held device. This can provide a true Frenet frame, i.e., X- and Y-vectors for the display, and also a Z-vector that points perpendicularly to the display. In fact, with various inertial clues from accelerometer, gyrometer, and other instruments that report their states in real time, it is possible to track the Frenet frame of the device in real time to provide a continuous 3D frame-of-reference. Once this continuous frame of reference is known, the position of a user's eyes may either be inferred or calculated directly by using a device's front-facing camera. With the position of the user's eyes and a continuous 3D frame-of-reference for the display, more realistic virtual 3D depictions of the objects on the device's display may be created and interacted with by the user.

摘要： Data indicating a problem in a network is derived by collecting reformatting requests from devices in the network. The reformatting requests are generated by the devices in response to problems the devices experience in communicating using the network. The reformatting requests are correlated to determine a pattern in the reformatting requests over a period of time, and data indicating a problem in the network is derived based on the pattern.

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： A bucket is capable of holding a sample container in a rotary centrifuge. The bucket has a receptacle to receive the sample container and a trunnion joined to the bucket. The trunnion has a plurality of cutouts that each define a flexible span that is sufficiently thin to flex under application of a centrifugal force generated by the rotary centrifuge, and pivot pins to that allows the bucket to pivot under the application of the centrifugal force. The receptacle has an open end having an internal surface with a tapering groove and a self-seating cap having pegs sized to fit in the tapering groove.

摘要： Image sensors have finite ranges of illuminance that may be captured. When the sensors for particular pixels receive an amount of light exceeding these finite ranges, the pixel values clip to the maximum pixel value. Systems and methods for estimating pixel values that are clipped or near clipping are provided. In one example, a method for processing image data includes determining that a first channel of the image data is saturated or near saturation. The method further includes computing a highlight recovery value for the first channel based upon alternative channels in the image data that are not saturated or near saturation. The highlight recovery value is applied to the first channel.

摘要： GPU fragment programs can be used to render images in a computer system. These fragment programs are generated from render trees, which specify one or more filters or functions to be applied to an input image to render an output image. It is not uncommon for successive frames to require application of substantially the same filters. Therefore, rather than regenerate and recompile new fragment programs for successive corresponding render trees, the render trees are substantially uniquely identified and cached. Thus, when a render tree is received, it can be identified, and this identifier (such as a hash) can be used to determine whether a corresponding fragment program has already been generated, compiled and cached. If so, the corresponding cached fragment program is retrieved and executed. If not, a fragment program for the newly received render tree is generated and cached.
摘要翻译： GPU片段程序可用于在计算机系统中呈现图像。这些片段程序是从渲染树生成的，它们指定要应用于输入图像以呈现输出图像的一个或多个过滤器或函数。连续的帧要求使用基本上相同的滤波器并不罕见。因此，渲染树不是重新生成并重新编译连续相应渲染树的新片段程序，而是基本上唯一地标识和缓存。因此，当接收到渲染树时，可以识别它，并且可以使用该标识符（例如散列）来确定是否已经生成，编译和高速缓存对应的片段程序。如果是，则检索并执行相应的缓存片段程序。如果没有，则生成并缓存新接收的渲染树的片段程序。

摘要： A technique for optimizing the rendering of such complex render-graphs caches intermediate buffers of nodes that are expected to be re-used after they've been rendered. The render-graph is examined to determine the number of re-uses of each node's output buffer, and the buffer is cached in memory until all the re-uses of the buffer have occurred. Once all the re-uses of the buffer have occurred, the buffer is removed from the cache. This technique guarantees that for a given render-graph, no nodes will be re-rendered, resulting in improved render performance.
