Abstract: A method to correct an autofocus operation of a digital image capture device based on an empirical evaluation of image capture metadata is disclosed. The method includes capturing an image of a scene (the image including one or more autofocus windows), obtaining an initial focus score for at least one of the image's one or more autofocus windows, obtaining image capture metadata for at least one of the one or more autofocus windows, determining a focus adjustment score for the one autofocus window based on a combination of the autofocus window's image capture metadata (wherein the focus adjustment score is indicative of the autofocus window's noise), and determining a corrected focus score for the one autofocus window based on the initial focus score and the focus adjustment score.

Abstract: An apparatus, method, and computer readable medium related to autofocusing a camera lens system. An initial image is captured at a first lens position and focus information is extracted with respect to a first plurality of focus windows. A second image is captured at a second lens position and focus information is extracted for a second plurality of focus windows that correspond to the first plurality of focus windows in the initial image. The focus information for corresponding windows is compared to determine whether the focus status in each window is improving or degrading; this determination reveals whether the lens is positioned in a desirable position with respect to the data revealed by the data extracted from the focus windows.

Abstract: Techniques to detect subject and camera motion in a set of consecutively captured image frames are disclosed. More particularly, techniques disclosed herein temporally track two sets of downscaled images to detect motion. One set may contain higher resolution and the other set lower resolution of the same images. For each set, a coefficient of variation may be computed across the set of images for each sample in the downscaled image to detect motion and generate a change mask. The information in the change mask can be used for various applications, including determining how to capture a next image in the sequence.

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, 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.

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: 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, etc., 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.

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.
