Abstract: A barcode decoding system and method are disclosed that use a data-driven classifier for transforming a potentially degraded barcode signal into a digit sequence. The disclosed implementations are robust to signal degradation through incorporation of a noise model into the classifier construction phase. The run-time computational cost is low, allowing for efficient implementations on portable devices. Implementations are disclosed for intelligent preview scaling, barcode-aware autofocus augmentation and multi-scale signal feature extraction.

Abstract: Methods, devices, and systems for continuous image capturing are described herein. In one embodiment, a method includes continuously capturing a sequence of images with an image capturing device. The method may further include storing a predetermined number of the sequence of images in a buffer. The method may further include receiving a user request to capture an image. In response to the user request, the method may further include automatically selecting one of the buffered images based on an exposure time of one of the buffered images. The sequence of images is captured prior to or concurrently with receiving the user request.

Abstract: A user interface can have one or more spaces presented therein. A space is a grouping of one or more program windows in relation to windows of other application programs, such that the program(s) of only a single space is visible when the space is active. A view can be generated of all spaces and their contents.

Abstract: 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 type of objects for an application's user interface. The application commits state changes of the layers of the layer tree. The application does not need to include explicit code for animating the changes to the layers. Instead, after a synchronization threshold has been met, 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, synchronized with the display. Portions of the render tree changing relative to prior versions can be tracked to improve resource management.

Abstract translation: 图形动画和合成操作框架具有用于与应用程序接口的层树和用于与渲染引擎进行连接的渲染树。 层树中的层可以是应用程序的用户界面的内容，窗口，视图，视频，图像，文本，媒体或其他类型的对象。 应用程序提交层树的层的状态更改。 该应用程序不需要包含用于动画化图层的更改的显式代码。 相反，在满足同步阈值之后，确定用于通过框架动画化状态的动画，其可以基于运动，可见性和转换来定义一组预定动画。 确定的动画显式应用于渲染树中的受影响的图层。 渲染引擎从渲染树渲染到与显示器同步的帧缓冲区。 可以跟踪渲染树相对于先前版本更改的部分，以改进资源管理。

Abstract: Systems, methods, and computer readable media to provide improved autofocus operations are described. In general, techniques are disclosed that show how to improve contrast-based autofocus operations by applying a novel threshold-and-select action to window-specific focus scores. More particularly, techniques disclosed herein may evaluate a multi-window autofocus area over a burst collected group of images. For each captured image, focus scores for each window within an autofocus area may be collected, aggregated and then consolidated to identify a single focus metric and its associated lens position for each window. The window-specific focus scores may be reviewed and selection of a “best” autofocus lens position made using a selection criteria. The specified criteria may be used to bias the selection to either a front-of-plane (macro) or back-of-plane (infinity) focus position.

Abstract: 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.
