摘要： A framework for performing graphics animation and compositing operations has a layer tree for interfacing with the application and a render tree for interfacing with a render engine. Layers in the layer tree can be content, windows, views, video, images, text, media, or any other type of object for a user interface of an application. The application commits change to the state of the layers of the layer tree. The application does not need to include explicit code for animating the changes to the layers. Instead, an animation is determined for animating the change in state. The determined animation is explicitly applied to the affected layers in the render tree. A render engine renders from the render tree into a frame buffer for display on the processing device. Those portions of the render tree that have changed relative to prior versions can be tracked to improve resource management.

摘要： This disclosure pertains to devices, methods, and computer readable media for performing positional sensor-assisted panoramic photography techniques in handheld personal electronic devices. Generalized steps that may be used to carry out the panoramic photography techniques described herein include, but are not necessarily limited to: 1.) acquiring image data from the electronic device's image sensor; 2.) performing “motion filtering” on the acquired image data, e.g., using information returned from positional sensors of the electronic device to inform the processing of the image data; 3.) performing image registration between adjacent captured images; 4.) performing geometric corrections on captured image data, e.g., due to perspective changes and/or camera rotation about a non-center of perspective (COP) camera point; and 5.) “stitching” the captured images together to create the panoramic scene, e.g., blending the image data in the overlap area between adjacent captured images. The resultant stitched panoramic image may be cropped before final storage.

摘要： Methods and apparatuses for anti-aliasing scan conversion. In one aspect of the invention, an exemplary method to scan convert an image on a data processing system includes: sampling the image in a first direction to generate first signals for points along a second line in a second direction using a closed form solution for a convolution integral with a first kernel; and weighting the first signals for the points according to a second kernel in the second direction to generate a second signal for a pixel. In one example according to this aspect, the closed form solution is tabulated in a look up table. After entries are looked up from the look up table according to the image along a first line in the first direction on a first point of the points, the entries are combined to generate one of the first signals for the first point.

摘要： A system, computer readable medium, and method for dynamically setting a camera's exposure parameters based on face detection are disclosed. When taking a picture or video of a person in front of a bright background, standard exposure algorithms tend to overexpose the background. In one embodiment disclosed herein, a face detection algorithm is run on the current picture or video frame, and the exposure metering region is inset over the detected face. Exposure time, gain, or other exposure parameters may be set based on the pixels within the exposure metering region. In another embodiment, the exposure metering region tracks a moving face according to lag parameters so that the exposure metering region remains substantially over the face. In yet another embodiment, a plurality of faces may be tracked, with the exposure parameters set based on a weighted average of the pixels within the plurality of face-containing exposure metering regions.

摘要： Systems, methods, and a computer readable medium for performing an improved blowout prevention process in an image capture device are provided to compensate for occurrences of exposure “blowouts,” i.e., areas in a captured image where pixel brightness exceeds the sensor's dynamic range of capturing capability. In one embodiment, the captured image's histogram may be analyzed to determine if the image is indicative of the presence of exposure blowouts. Once it has been determined that there likely are blowouts in the image, an exposure bias for the image capture device may be set accordingly. Particularly, the exposure value (EV) for the image capture device may be gradually corrected, e.g., by one-eighth of a stop per captured frame, until the image histogram is no longer indicative of blown out regions, at which point the image capture device's exposure value may gradually be corrected back to “normal,” i.e., non-exposure bias compensated, levels.

摘要： Systems, methods, and a computer readable medium for an improved automatic exposure algorithm attempt to classify an image into a particular “scene category,” and, based on the determined scene category, meter the scene according to a generated metering weighting matrix. In one embodiment, the average luminance is calculated for a central exposure metering region of the image and a plurality of peripheral exposure metering regions surrounding the central exposure metering region. Based on comparisons of the average luminance values of the peripheral exposure regions to the average luminance of the central exposure region, a target metering weighting matrix may be generated. In another embodiment, the scene category corresponds to a predetermined metering weighting matrix. In video applications, it may be desirable to reduce oscillations in metering parameter values to limit any visually jarring effects on the camera's preview screen by only adjusting metering parameter values when predetermined criteria are met.
摘要翻译：用于改进的自动曝光算法的系统，方法和计算机可读介质尝试将图像分类为特定的“场景类别”，并且基于所确定的场景类别，根据生成的计量加权矩阵来计量场景。在一个实施例中，对于图像的中央曝光测光区域和围绕中央曝光测光区域的多个周边曝光测光区域计算平均亮度。基于外围曝光区域的平均亮度值与中央曝光区域的平均亮度的比较，可以生成目标计量加权矩阵。在另一个实施例中，场景类别对应于预定计量加权矩阵。在视频应用中，可能希望通过仅在满足预定标准时调整测光参数值，减少计量参数值中的振荡，以限制对相机预览屏幕的任何视觉刺激的影响。

摘要： Techniques to generate partial display updates in a buffered window system in which arbitrary visual effects are permitted to any one or more windows (e.g., application-specific window buffers) are described. Once a display output region is identified for updating, the buffered window system is interrogated to determine which regions within each window, if any, may effect the identified output region. Such determination considers the consequences any filters associated with a window impose on the region needed to make the output update.

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.
