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.

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 Gaussian blur approximation is applied to an image by repeated down-sampling operations followed by an up-sample operation. By using a truncated Gaussian filter as the down-sample filter, the frequency spectrum removed during down-sampling operations closely approximates the frequency spectrum lost during a true Gaussian blur operation. While any “good” up-sample filter may be used, up-sampling via linear interpolation may be especially beneficial in systems having a dedicated graphics processing unit. One benefit of the described technique is that it is computationally less costly to implement than a Gaussian blur. Another benefit is that this computational benefit increases as the size of the blur increases—becoming significant even for small blurs. Yet another benefit of the invention is that a judicious selection of pixel address to convolve with the filter leads to substantially reduced number of texture lookups required to effect a convolution.
摘要翻译：高斯模糊近似通过重复的下采样操作随后进行上采样操作来应用于图像。通过使用截断高斯滤波器作为下采样滤波器，在下采样操作期间去除的频谱与真正的高斯模糊操作期间的频谱损失密切相近。虽然可以使用任何“良好”的抽样滤波器，但通过线性插值的上采样在具有专用图形处理单元的系统中尤其有利。所描述的技术的一个好处是，与高斯模糊相比，在计算上成本较低。另一个好处是，随着模糊大小的增加，这种计算效益即使对于小的模糊也变得显着。本发明的另一个好处是，与滤波器卷积的像素地址的明智选择导致实现卷积所需的纹理查找的数量大大减少。

摘要： Techniques to effect arbitrary visual effects using fragment programs executing on a programmable graphics processing unit are described. In a first technique, visual effects are applied to a buffered window system's assembly buffer prior to compositing a target window. In a second technique, visual effects are applied to a target window as it is being composited into the system's assembly buffer. In a third technique, visual effects are applied to a system's assembly buffer after compositing a target window. Finally, in a fourth technique, visual effects are applied to the system's assembly buffer as it is transmitted to the system's frame-buffer.

摘要： Methods and apparatuses for resizing buffered windows. In one aspect of the invention, a method to resize a buffered window on a data processing system includes: determining an estimated size for a window which has a first pixel image of a first size buffered in a first window buffer; allocating a second window buffer which is large enough to buffer the window in the estimated size; and buffering a second pixel image of the window in a second size in the second window buffer. In one example according to this aspect, a portion of a frame buffer is updated to the second pixel image to display the window in the second size. A portion of the second window buffer, storing the data that represents the second pixel image, is clipped to update the corresponding portion of the frame buffer.

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. In determining the animation, the framework 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 for display on the computer system. Those portions of the render tree that have changed relative to prior versions can be tracked to improve resource management.

摘要： Systems, methods, and computer readable media for dynamically adjusting an image capture device's autofocus (AF) operation based, at least in part, on the device's orientation are described. In general, information about an image capture device's orientation may be used to either increase the speed or improve the resolution of autofocus operations. More particularly, orientation information such as that available from an accelerometer may be used to reduce the number of lens positions (points-of-interest) used during an autofocus operation, thereby improving the operation's speed. Alternatively, orientation information may be used to reduce the lens' range of motion while maintaining the number of points-of-interest, thereby improving the operation's resolution.
