摘要： Systems, methods, and computer readable media for performing auto-exposure operations in a digital image capture device. An image capture device's auto-exposure settings may be automatically adjusted by generating and then combining, in a dynamically weighted fashion, two sets of exposure values. One set of exposure values may be based on detected faces while the other set may be based on the image as a whole. Each set of exposure values may include a “measured” value and a “target” value, wherein each of these values may, in turn, be based on one or more (different) aspects of the image. Illustrative digital image capture devices in which the disclosed technology may be used include, but are not limited, to portable digital cameras, mobile telephones, personal digital assistants, mobile music and video devices, and portable computer platforms such as notebook and tablet computers.

摘要： One or more portions of a cascaded face detection process, such as a process using a number of stages in which each stage includes classifiers having one or more associated features, can be parallelized. For instance, multiple pixels associated with an image can be evaluated in parallel, including simultaneously evaluating one or more features for each of the selected pixels. As a result, the number of operations required to perform the face detection processing can be reduced. Further, pre-processing can be performed to identify one or more image regions for which face detection process need not be performed. For instance, either or both of a skin-tone measure and a variance measure can be used to identify image regions in which a face is unlikely to be depicted.

摘要： Several methods and apparatuses for implementing automatic exposure mechanisms for image capturing devices are described. In one embodiment, an orientation detector located in the device determines orientation data for the device. The automatic exposure mechanism projects an orientation vector into an image plane of an image sensor. Next, the automatic exposure mechanism adjusts an initial position of a metering area used for automatic exposure towards a target position based on the projected orientation vector. The automatic exposure mechanism optionally dampens the adjustment of the metering area.

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： Several methods for operating a built-in digital camera of a portable, handheld electronic device are described. In one embodiment, the device receives a user selection (e.g., tap, tap and hold, gesture) of a region displayed on the display screen (e.g., touch sensitive screen). A touch to focus mode may then be initiated in response to the user selection and exposure and focus parameters determined and adjusted. Then, an automatic scene detection mechanism can determine whether a scene has changed. If the scene has changed, then the touch to focus mode ends and a default automatic focus mode initiates. This mode sets a new exposure metering area and focus area prior to determining and adjusting exposure and focus parameters, respectively.

摘要： A graphics animation and compositing operations framework 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 other types of objects for an application's user interface. The application commits state changes to 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 by the framework which can define a set of predetermined animations based on motion, visibility, and transition. 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. Portions of the render tree changing relative to prior versions can be tracked to improve resource management.

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.
