Patent number: 6301447Abstract: A method and system for the creation and viewing of stereoscopic immersive images. By creating two immersive images from an offset camera platform, the illusion of depth can be provided by a left and right view in the form of an interactive panoramic image. By capturing two immersive images on a fixture with horizontal separation of the centers of each immersive image, each constructed from a sequence of fisheye images that are captured in a constant direction and seamed together, two files that can be used to produce a stereoscopic display are created. The resulting files can be displayed using any number of stereoscopic displays including dual monitors, one for each eye, or shuttered displays for each eye from a single monitor, or displays with polarized filters directing separate views to each eye.Type: GrantFiled: October 8, 1998Date of Patent: October 9, 2001Assignee: Interactive Pictures CorporationInventors: Laban P.

Patent number: 6243131Abstract: A method for capturing and directly scanning a rectilinear imaging element using a non-linear scan is incorporated into a single chip comprising at least a sensor array and an MSD. The method directly addresses each picture element of an analog image captured with an imaging device having either a partial spherical field of view or a conventional two-dimensional field of view. An image transform processor is used to process the captured image depending upon the particular portion of interest of the image. In the case of a non-linear scan, the image transform processor is provided with the capability of geometrically filtering the portion of interest of the captured image such that a two-dimensional, undistorted image is displayed at the monitor. A CMOS active pixel image sensor (APS) or Charge Injection Diode (CID) camera array are used to capture the image to be scanned. The image transform processor of the present invention is a Mixed-signal Semiconductor Device (MSD).Type: GrantFiled: January 17, 1995Date of Patent: June 5, 2001Assignee: Interactive Pictures CorporationInventor: H.

Patent number: 6201574Abstract: A device for omnidirectional image viewing providing pan-and-tilt orientation, rotation, and magnification within a hemispherical field-of-view that utilizes no moving parts. The imaging device is based on the effect that the image from a fisheye lens, which produces a circular image of an entire hemispherical field-of-view, can be mathematically corrected using high-speed electronic circuitry. More specifically, an incoming fisheye image is captured on a Charge Coupled Diode array in such a way as to remove the distortion caused by the lens by locating the picture pickup elements in a nonlinear manner described herein. As a result, this device can accomplish the functions of pan, tilt, rotation, and zoom throughout a hemispherical field-of-view without the need for any mechanical mechanisms. The preferred embodiment of the image capture device can provide corrected images at standard video frame rates, compatible with standard video equipment.Type: GrantFiled: February 5, 1997Date of Patent: March 13, 2001Assignee: Interactive Pictures CorporationInventor: H.

Patent number: 6147709Abstract: A method of inserting a high resolution image into a low resolution interactive image provides a greater sensation of virtual reality (presence) because increased magnification of the low resolution image, typically a wide angle image, reduces the sensation of virtual presence in the image. For example, according to the invention, as an image of the wall of an art gallery becomes magnified in a virtual presence experience, a rectangular or other planar image portion such as a painting that the user zooms on is replaced with a high resolution image stored and associated in memory. The virtual presence may be achieved by high resolution scanning a desired section of an image portion for overlay into the image scanned into a second memory at lower resolution. The high resolution image for insertion may be a dewarped portion of a fish-eye lens captured interactive image.Type: GrantFiled: April 7, 1997Date of Patent: November 14, 2000Assignee: Interactive Pictures CorporationInventors: H.

Patent number: 5903319Abstract: A method and apparatus for the elimination of temporal and spacial distortions from interlaced video signals, particularly those that occur in signals associated with affine transformations. This elimination is particularly of value for signals that have been magnified so as to prevent the visual appearance of reverse movement of moving images. The removal of these distortions is achieved by sequentially inputting the images fields into three field buffers, updating the data in a rotary manner. This data is withdrawn from any two of the field buffers, while the third field buffer is being updated, and averaging the data from the two. When such averaged data is displayed, there is no apparent reverse direction motion to the image. The method and apparatus are applied to a system wherein there is affine transformation to achieve selected pan, tilt, rotation and magnification of images during the correction of distorted images received from a wide angle lens.Type: GrantFiled: January 17, 1995Date of Patent: May 11, 1999Assignee: Interactive Pictures CorporationInventors: Nicholas Busko, H.
