摘要： The use of resources on a computing device can be optimized for current conditions to reduce or minimize the amount of resources needed to provide a sufficient level of performance for various types of tasks. In some embodiments, one or more optimization algorithms can analyze information such as a type of task to be performed and the state of one or more environmental conditions to attempt to select a number and configuration of components, such as cameras and illumination elements, to use in performing the tasks. The performance of the tasks can be monitored, and the selection or states updated in order to maintain a sufficient level of performance without using more resources than are necessary.

摘要： A user attempting to obtain information about an object can capture image information including a view of that object, and the image information can be used with a matching or identification process to provide information about that type of object to the user. Information about the orientation of the camera and/or device used to capture the image can be provided in order to limit an initial search space for the matching or identification process. In some embodiments, images can be selected for matching based at least in part upon having a view matching the orientation of the camera or device. In other embodiments, images of objects corresponding to the orientation can be selected. Such a process can increase the average speed and efficiency in locating matching images. If a match cannot be found in the initial space, images of other views and categories can be analyzed as well.

摘要： An electronic device can utilize one or more sensors and/or imaging elements to determine the relative position of at least one light source relative to the device. In various embodiments, the intensity of light can be determined in various directions around the device. By determining the relative intensity around the device, an approximate direction of one or more light sources can be determined. Utilizing the relative position of each light source, the electronic device can properly light or shade a graphical object to be rendered by the device, or otherwise process image information captured by the device.

摘要： An electronic device can utilize one or more sensors and/or imaging elements to determine the relative position of at least one light source relative to the device. In various embodiments, occlusions can be used to cause shadows to be cast on certain sensors. By determining the relative position of each occlusion relative to the sensor, the device can determine an approximate direction of the light source. Utilizing the relative position of a light source, the electronic device can properly light or shade a graphical object to be rendered by the device or otherwise process image information captured by the device.

摘要： Content displayed on a display element of a computing device can be rendered from a viewpoint that updates with changes in the relative position of a user's head, or other such feature, with respect to the device. At least one camera of the device can attempt to track the relative position in order to determine the proper viewpoint. When the user's head can no longer be seen, or when confidence in the determined relative position drops below an acceptable value, for example, the device can utilize information from another source, such as a motion or rotation sensor, to attempt to estimate the current position of the user's head. Physical limitations of the user with respect to the device also can be used to improve the accuracy of the determination.

摘要： Image information displayed on an electronic device can be modified based at least in part upon a relative position of a user with respect to a device. Mapping, topological or other types of positional data can be used to render image content from a perspective that is consistent with a viewing angle for the current relative position of the user. As that viewing angle changes, as a result of movement of the user and/or the device, the content can be re-rendered or otherwise updated to display the image content from a perspective that reflects the change in viewing angle. Simulations of effects such as parallax and occlusions can be used with the change in perspective to provide a consistent user experience that provides a sense of three-dimensional content even when that content is rendered on a two-dimensional display. Lighting, shading and/or other effects can be used to enhance the experience.

摘要： The computational resources needed to perform processes such as image recognition can be reduced by determining appropriate frames of image information to use for the processing. In some embodiments, infrared imaging can be used to determine when a person is looking substantially towards a device, such that an image frame captured at that time will likely be adequate for facial recognition. In other embodiments, sound triangulation or motion sensing can be used to assist in determining which captured image frames to discard and which to select for processing based on any of a number of factors indicative of a proper frame for processing.

摘要： A user can be identified and/or authenticated to an electronic device by analyzing aspects of a motion or gesture made by that user. At least one imaging element of the device can capture image information including the motion or gesture, and can determine time-dependent information about that motion or gesture in two or three dimensions of space. The time-dependent information can be used to identify varying speeds, motions, and other such aspects that are indicative of a particular user. The way in which a gesture or motion is made, in addition to the motion or gesture itself, can be used to authenticate an individual user. While other persons can learn the basic gesture or motion, the way in which each person makes that gesture or motion will generally be at least slightly different, which can be used to prevent unauthorized access to sensitive information, protected functionality, or other such content.

摘要： Image capture can be improved by capturing a sequence of images and analyzing the images to select the image with the least blur and/or an acceptable amount of blur. Gradients can be calculated for at least a portion of the images, and gradient histograms generated. Two or more component curves can be fit to each histogram, such as by using a Gaussian mixture model, and the curves can be compared to determine an amount of variation between the curves. The image with the smallest differences between component curves, or with differences less than a specified blur threshold, can be selected as a sufficiently sharp image and provided for viewing, processing, or another intended purpose of the image to be captured.
