Patent number: 9204031Abstract: The method includes changing a focal length of a camera device while capturing one or more frames of sensor data from a sensor array of the camera device by sequentially reading signals from different areas of the sensor array, such that different sections of each of the one or more frames corresponds to sensor data captured at different focal lengths of the camera device. The method further includes deriving focus statistics from the one or more captured frames, each focus statistic providing a measure of an extent to which a section of a frame to which the focus statistic relates is in focus at a given focal length; identifying from the focus statistics an optimal focal length at which an optimally focused image can be captured; and adapting the focal length of the camera device in accordance with the optimal focal length.Type: GrantFiled: May 28, 2013Date of Patent: December 1, 2015Assignee: STMICROELECTRONICS (RESEARCH & DEVELOPMENT) LIMITEDInventor: William Foote

Patent number: 8698945Abstract: In automatically focusing on a subject in the field of view of a camera device, the camera device sets a focal length successively at one or more focal positions with an angle of the focus plane tilted so as not to be orthogonal to a normal optical path through the camera device. An image is taken at each of the focal positions. A comparison of data from each image is made so as to determine best focus. This comparison includes comparing data from at least two different locations along the tilted focus plane of at least one of the images.Type: GrantFiled: July 25, 2011Date of Patent: April 15, 2014Assignee: STMicroelectronics (Research & Development) LimitedInventor: William Foote

Patent number: 8516018Abstract: Disclosed are apparatus and methods for managing image storage. An image source of a computing device can include one or more functions and a reference to image views for an image object, such as a bitmap object. The image object can include a reference to first storage that stores an image. The image source, the reference to the image views, and the image object are stored in a managed portion of memory. The first storage is stored in an unmanaged portion of memory differing from the managed portion. The computing device displays the image. Upon determining to discontinue displaying the image, an unbind function of the image source is called. The image source responsively discontinues display of the image. The image source receives an indication that the image views are solely weakly referenced. In response to the indication, the image source deallocates the first storage.Type: GrantFiled: April 6, 2012Date of Patent: August 20, 2013Assignee: Google Inc.Inventors: William Foote, Alejandro Nijamkin

Patent number: 8280197Abstract: Disclosed are apparatus and methods for loading images. A request can be received at a computing device to display a plurality of images on the computing device. In response to the request, the computing device can load, in parallel, the plurality of images into storage of the computing device. The computing device can determine whether an image of the plurality of images is to be used. In response to determining that the image is to be used, the computing device can mark the image as loaded. In response to determining that the image is to not be used, the computing device can mark the image as no-image. Only images marked as loaded can be provided for display.Type: GrantFiled: May 1, 2012Date of Patent: October 2, 2012Assignee: Google Inc.Inventors: William Foote, Alejandro Nijamkin

Publication number: 20050105044Abstract: Wavefront measuring systems and methods are disclosed which may be employed, for example, in detecting phase aberrations in a spectacle lens and in an eye. Various embodiments include disposing a modulation pattern in the path of a return beam from the spectacle lens or the eye, and imaging a diffraction pattern at a self-imaging plane relative to the modulation pattern with a detector. The diffraction pattern is analyzed and the results are used to produce a representation of the wavefront phase characteristics that describe aberrations in the lens or eye being measured. Illumination and processing techniques for improving the measurement results are dislcosed. Various embodiments comprise systems adaptable to both measure aberrations in lenses in spectacles as well as in a patient's eyes.Type: ApplicationFiled: October 22, 2004Publication date: May 19, 2005Inventors: Laurence Warden, John Ferro, Andreas Dreher, William Foote
