Patent number: 9807287Abstract: Various approaches to imaging involve selecting directional and spatial resolution. According to an example embodiment, images are computed using an imaging arrangement to facilitate selective directional and spatial aspects of the detection and processing of light data. Light passed through a main lens is directed to photosensors via a plurality of microlenses. The separation between the microlenses and photosensors is set to facilitate directional and/or spatial resolution in recorded light data, and facilitating refocusing power and/or image resolution in images computed from the recorded light data. In one implementation, the separation is varied between zero and one focal length of the microlenses to respectively facilitate spatial and directional resolution (with increasing directional resolution, hence refocusing power, as the separation approaches one focal length).Type: GrantFiled: June 30, 2015Date of Patent: October 31, 2017Assignee: Board of Trustees of the Leland Stanford Junior UniversityInventors: Yi-Ren Ng, Patrick M. Hanrahan, Mark A. Horowitz, Marc S. Levoy

Patent number: 9292628Abstract: A method of generating a statistical model for a dataset operates at a computer system having one or more processors and memory. The memory stores one or more programs configured for execution by the one or more processors. The process receives a visual specification. The visual specification defines a graphical representation of a portion of the dataset. The visual specification includes a first field and a second field of the dataset. The method determines a set of data properties for each of the first and second fields. The process then generates a statistical model of a mathematical relationship between the first and second fields based on the data properties of the first and second fields and data values associated with the first and second fields in the dataset. The process displays the graphical representation and the statistical model superimposed on the graphical representation.Type: GrantFiled: October 14, 2014Date of Patent: March 22, 2016Assignee: Tableau Software, Inc.Inventors: Andrew C. Beers, Matthew W. Eldridge, Patrick M. Hanrahan, Jonathan E. Taylor

Patent number: 8953064Abstract: Image data is processed to facilitate focusing and/or optical correction. According to an example embodiment of the present invention, an imaging arrangement collects light data corresponding to light passing through a particular focal plane. The light data is collected using an approach that facilitates the determination of the direction from which various portions of the light incident upon a portion of the focal plane emanate from. Using this directional information in connection with value of the light as detected by photosensors, an image represented by the light is selectively focused and/or corrected.Type: GrantFiled: September 16, 2014Date of Patent: February 10, 2015Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Yi-Ren Ng, Patrick M.

Patent number: 8860727Abstract: A method of automatically generating models from a dataset includes multiple steps. First, a description of a view of a dataset is provided. The description includes multiple fields associated with the dataset. Next, a set of properties is determined for each of the multiple fields.

Patent number: 8358354Abstract: Digital images are computed using an approach for correcting lens aberration. According to an example embodiment of the present invention, a digital imaging arrangement implements microlenses to direct light to photosensors that detect the light and generate data corresponding to the detected light. The generated data is used to compute an output image, where each output image pixel value corresponds to a selective weighting and summation of a subset of the detected photosensor values. The weighting is a function of characteristics of the imaging arrangement. In some applications, the weighting reduces the contribution of data from photosensors that contribute higher amounts of optical aberration to the corresponding output image pixel.Type: GrantFiled: May 8, 2012Date of Patent: January 22, 2013Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Yi-Ren Ng, Patrick M.
