Abstract: Embodiments of the present invention are directed toward providing refocusable image. Refocusable images are images that, after being captured, can be refocused, or adjusted to have a different focal length. The embodiments described herein can utilize a mobile user device, such as a smartphone, without the need for specialized hardware. A camera of the mobile device can be configured to take a series of images in succession over a short period of time in which the focal length of the camera is varied so that each image has a different focal length. An image stack is created by aligning the images, and images are processed to determine which image has the highest contrast (i.e., is in focus) for each region of the image stack. Embodiments can further include displaying a first image of the series of images.

Abstract translation: 本发明的实施例旨在提供可重新聚焦的图像。 可重构的图像是在被捕获之后可以重新聚焦或调整为具有不同焦距的图像。 本文描述的实施例可以利用诸如智能电话的移动用户设备，而不需要专门的硬件。 移动设备的相机可以被配置为在相机的焦距变化的短时间内连续拍摄一系列图像，使得每个图像具有不同的焦距。 通过对齐图像来创建图像堆叠，并且处理图像以确定针对图像堆叠的每个区域的哪个图像具有最高的对比度（即焦点）。 实施例还可以包括显示该系列图像的第一图像。

Abstract: Methods and devices for camera aided motion direction and speed estimation are disclosed. The method of determining position characteristics of a mobile device comprises capturing a plurality of images that represent views from the mobile device, adjusting perspectives of the plurality of images based at least in part on an orientation of the mobile device, determining a misalignment angle with respect to a direction of motion of the mobile device using the plurality of images, and storing the misalignment angle and the direction of motion in a storage device.

Abstract: A mobile device uses data from one or more sensors to determine a user context, such as a motion state of the user, and adjusts at least one camera feature selected form a group consisting of continuous auto-focus, auto-white balance, video encode quality, frame rate, search range used for focusing, and exposure mode based on the user context. The user context may include, e.g., at least one of panning, walking, standing, sitting, and traveling in a moving vehicle.
