Filed:

Nov 1, 1999

Appl. No.:

09/431000

Inventors:

Roger D. Melen - Los Altos Hills CA

Assignee:

Canon Kabushiki Kaisha - Tokyo

International Classification:

H01L 2700

US Classification:

2502081, 378146, 345506

Abstract:

In generation of combined image data from first and second scans of an image, artifacts caused by motion between the first and second scans are reduced. Digital pixel data for the first and second scans are stored. A translational second scan is generated using the first and second scans, the translational second scan having new digital pixel data which compensates for motion artifacts between the first and second scans. The combined image data is generated by combining the digital pixel data of the first scan with the new digital pixel data of the translational second scan, with the translational second scan being weighted before it is summed with the digital pixel data of the first scan.

382154, 382232, 715513

Abstract:

A computer implemented method for displaying a stereoscopic image ( ) represented in a portable document format encoded file ( ) includes identifying in the encoded file ( ) at least two component images ( A-B) combinable to create the stereoscopic image ( ); combining the component images ( A-B) to create the stereoscopic image ( ); and displaying the stereoscopic image ( ) on a stereoscopic display device ( ). A system for representing and displaying a stereoscopic image ( ) in a portable document format encoded file ( ) includes an encoded file creator ( ), an encoded file reader ( ), a stereoscopic imager ( ), and an image cache ( ).

Appl. No.:

09/431418

Inventors:

Roger D. Melen - Los Altos Hills CA

Assignee:

Canon Kabushiki Kaisha - Tokyo

International Classification:

G06K 900

US Classification:

382154, 382285, 382289, 348 42

Abstract:

Cameras ( ) produce first and second images ( ) of an object ( ) from different viewpoints. An image partitioning module ( ) partitions the images ( ) into a plurality of vertically striped regions ( ), such that each region ( ) of the first image ( ) corresponds to a region ( ) of the second image ( ). A region alignment module ( ) vertically shifts a region ( ) of the first image ( ) in a direction calculated to vertically align a portion ( ) of the region ( ) with a substantially matching portion ( ) of the corresponding region ( ). A disparity calculation module ( ) calculates at least one disparity value between at least a portion ( ) of the vertically shifted region ( ) and at least a portion ( ) of the corresponding region ( ).

International Classification:

US Classification:

382132, 382154, 378 41

Abstract:

A radiographic imaging system ( ) comprises an X-ray tube ( ), a sensor plate ( ), and a graphics engine ( ). The tube ( ) and the sensor plate ( ) rotate synchronously about a patient ( ) and expose a stereoscopic pair of images which are transmitted to the graphics engine ( ). The graphics engine ( ) determines ( ) the geometry of the system ( ). If ( ) the pair of images are toed-in relative to each other, the graphics engine ( ) converts ( ) the images into a parallel geometry. Likewise, the graphics engine ( ) also processes ( ) the images for keystone distortion, if necessary. Simply flipping the images in the stereo pair distorts the depth of objects in the stereoscopic image. Instead of simply flipping the images, it is desirable to âgo behindâ the screen ( A) and look at the image from the back. In order to produce a stereoscopic image having this viewpoint, the graphics engine ( ) uses the geometry of the radiographic system ( ) to adjust ( ) the screen parallax of the image after the constituent images are flipped ( ) and provide the desired three-dimensional perspective.

Abstract:

The group interaction system comprises a plurality of vehicle navigation systems that are capable of communicating with one another, displaying the location of other vehicle navigation systems in a group, and receiving selection of certain vehicle navigation systems in the group and selection of an application for interaction among the selected vehicle navigation systems. A group of vehicle navigation systems to interact with is established. One or more of other vehicle navigation systems to interact with the vehicle navigation system. An application is also selected on the vehicle navigation system for interaction with the selected other vehicle navigation systems. In response, the vehicle navigation system runs the selected application with respect to the selected other navigation systems.

Abstract:

The present invention provides a system, method and computer program product for developing distributed applications, integrating component programs, integrating enterprise applications and managing change. The invention provides for an infrastructure where component programs that are the computational logic of the distributed application are installed over a network of computing units having controller programs running on each of these computing units. The invention provides for separating the concerns of computation, installation, execution and monitoring of the distributed application in terms of time, space and people involved. This is accomplished as the component programs simply perform the computation task and the communication between the component programs and their monitoring is handled by the controller programs.
