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 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： 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： A system and method of rendering overlapping layers in a computer display, such as a windowing system, employs front-to-back assembly of the displayed image. An arbitrary number of overlapping elements, such as windows, can be presented, without requiring temporary storage space or additional off-screen buffers. The front-to-back assembly technique minimizes the number of memory transfers performed in connection with rendering an image, and avoids unnecessary reading and processing of pixels that will not contribute to the final image. Special effects such as semi-transparency, shadows, and irregular shapes can be accommodated and processed in an efficient manner.

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： Devices, methods, and computer readable media for performing image orientation detection using image processing techniques are described. In one implementation, an image processing method is disclosed that obtains image data from a first image captured by an image sensor (e.g., from any image capture electronic device). Positional sensor data captured by the device and corresponding to the image data may also be acquired (e.g., through an accelerometer). If the orientation of the device is not reliably discernible from the positional sensor data, the method may attempt to use rotationally invariant character detection metrics to determine the most likely orientation of the image, e.g., by using a decision forest algorithm. Face detection information may be used in conjunction with, or as a substitute for, the character detection data based on one or more priority parameters. Image orientation information may then be included within the image's metadata.

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： An apparatus, method, computer useable medium, and processor programmed to automatically generate tone mapping curves in a digital camera based on image metadata are described. Rather than having a static tone mapping curve for all images, the curve can be varied automatically based on, e.g., the brightness histogram of the image. In one embodiment, a certain percentage of the least bright pixels and a certain percentage of the brightest pixels can be disregarded, while the remaining pixels can be linearly stretched to encompass the original range of brightness values. Based on the distribution of the resultant stretched brightness histogram, slopes for the low end (S0) and high end (S1) of the tone mapping curve can be independently determined, and the tone mapping curve can be automatically generated. The improved, automatically generated tone mapping curve may be able to lift shadows more aggressively and/or increase the dynamic range of the image.
