Method And Apparatus For Beam Deflection Using Multiple Beam Scanning Galvanometers

US Patent:
6628442, Sep 30, 2003
Filed:
Apr 21, 2000
Appl. No.:
09/556489
Inventors:
David DiFrancesco - San Francisco CA
James Burgess - Richmond CA
Assignee:
Pixar Animation Studios - Emeryville CA
International Classification:
G02B 2608
US Classification:
359202, 359204
Abstract:
The invention is a method and apparatus for deflecting a beam using multiple beam scanning galvanometers. One or more embodiments of the invention comprise a system for deflecting an energy beam comprising a first reflective surface for directing an incident beam, a first galvanometer coupled to the first reflective surface for rotating the first reflective surface about a first axis, a second reflective surface for directing the incident beam after directed by the first reflective surface, and a second galvanometer coupled to the second reflective surface for rotating the second reflective surface about a second axis, the second galvanometer positioned remote from the first galvanometer. In one or more embodiments, the system is a part of a laser film recorder. In such an embodiment, the incident beam comprises combined red, green and blue laser beams. The incident beam is directed by the second reflective surface at a film surface.

Flat Panel Image To Film Transfer Method And Apparatus

US Patent:
7463821, Dec 9, 2008
Filed:
Aug 8, 2003
Appl. No.:
10/637744
Inventors:
David DiFrancesco - San Francisco CA, US
Babak Sanii - San Francisco CA, US
Assignee:
Pixar - Emeryville CA
International Classification:
H04N 5/00
US Classification:
386130
Abstract:
A method for forming an image transfer apparatus includes providing first image data to a flat-panel display, displaying a first output image on the flat-panel display in response to the first image data, wherein the first output image includes an optical distortion associated with a film disposed onto a front transparent media of the flat-panel display, recording the first output image onto film media with a film recorder movably coupled to the flat-panel display, producing a complementing image in response to the first output image as recorded on the film media, and disposing the complementing image on an optical path of the film recorder.

Configurable Flat Panel Image To Film Transfer Method And Apparatus

US Patent:
7576830, Aug 18, 2009
Filed:
Aug 8, 2003
Appl. No.:
10/638135
Inventors:
David DiFrancesco - San Francisco CA, US
Assignee:
Pixar - Emeryville CA
International Classification:
G03B 19/18
US Classification:
352 44
Abstract:
A method for a film recorder includes displaying a plurality of images on a modified liquid crystal display movably coupled to the film recorder, wherein the modified liquid crystal display panel comprises a liquid crystal display panel with only a single polarizing media layer, disposing a linearly polarizing filter in an optical path of the film recorder, orienting the linearly polarizing filter in a first orientation relative to the modified liquid crystal display panel to thereby configure the film recorder to receive the plurality of images as positive images, and orienting the linearly polarizing filter in a second orientation relative to the modified liquid crystal display panel to thereby configure the film recorder to receive the plurality of images as negative images.

Video To Film Flat Panel Digital Recorder And Method

US Patent:
7787010, Aug 31, 2010
Filed:
Oct 31, 2003
Appl. No.:
10/700299
Inventors:
David DiFrancesco - San Francisco CA, US
Assignee:
Pixar - Emeryville CA
International Classification:
H04N 5/253
US Classification:
348 96, 348 97
Abstract:
A method for recording video images onto film media includes orienting a flat panel display relative to a film recording device, receiving a first frame of video data and a second frame of video data, displaying a first display image on the flat panel data, wherein the first display image is determined in response to the first frame of video data, and while displaying the fist display image on the flat panel display, exposing a portion of the film media with the film recording device.

Automatic Print And Negative Verification Methods And Apparatus

US Patent:
8233693, Jul 31, 2012
Filed:
Dec 17, 2007
Appl. No.:
11/958151
Inventors:
David DiFrancesco - Point Richmond CA, US
Dominic Glynn - Berkeley CA, US
Hee Soo Lee - San Francisco CA, US
Assignee:
Pixar - Emeryville CA
International Classification:
G06K 9/00
US Classification:
382141
Abstract:
A method for inspecting a reel of motion picture film including a first plurality of frames of film, the method includes receiving the first plurality of frames of motion picture film to determine a first plurality of digital data, receiving a second plurality of digital data associated with source data, comparing digital data from the first plurality of digital data to respective digital data of the second plurality of digital data to determine plurality of anomalies associated with the first plurality of frames of motion picture film, and recording the plurality of anomalies associated with the first plurality of frames of motion picture film in a log.

Abstract:
A method for specifying an animatronics unit includes receiving a force-based software model for the animatronics unit, receiving a kinematics-based software model for the animatronics unit, receiving animation data for animating the kinematics-based software model, wherein the animation data comprises artistically determined motions for the kinematics-based software model by a user, determining a plurality of driving signals in response to the animation data, animating the force-based software model of the animatronics unit in response to the plurality of driving signals, displaying animation of the force-based software model determined in response to the plurality of driving signals, and determining a specification for construction of the animatronics unit in response to animation of the force-based software model.

Super Light-Field Lens

US Patent:
8502909, Aug 6, 2013
Filed:
Mar 4, 2010
Appl. No.:
12/717842
Inventors:
David DiFrancesco - Point Richmond CA, US
Thomas Douglas Selkirk Duff - Berkeley CA, US
Mark VandeWettering - El Sobrante CA, US
Peter Flowers - Milton MA, US

Abstract:
Light field imaging systems, and in particular light field lenses that can be mated with a variety of conventional cameras (e. g. , digital or photographic/film, image and video/movie cameras) to create light field imaging systems. Light field data collected by these light field imaging systems can then be used to produce 2D images, right eye/left eye 3D images, to refocus foreground images and/or background images together or separately (depth of field adjustments), and to move the camera angle, as well as to render and manipulate images using a computer graphics rendering engine and compositing tools.
