Patent number: 10038841Abstract: A wide-angle camera emulating a PTZ camera via image data processing is used to generate a panoramic image of multiple regions for ease of viewing. A client can specify multiple regions for extraction from the panoramic image to stream to a separate server for further image processing and analysis.Type: GrantFiled: September 4, 2012Date of Patent: July 31, 2018Assignee: Grandeye Ltd.Inventor: Mark Kenneth Davey

Patent number: 8860780Abstract: A system and method for automatically rotating a view of a wide-angle video camera. Preferred embodiments include automatic rotating of a stereographically projected view using a transformation engine which is capable of extracting a plurality of views under a remote pan tilt zoom (PTZ) control. In one example embodiment, when the center point of a video image of a selected view or region of interest is tilted through a direction which is perpendicular to the plane of the camera mounting (i.e., vertical when the camera is mounted on a ceiling) then the output image is automatically rotated 180 degrees about the pan axis. In preferred embodiments, the control circuitry then temporarily reverses interpretation of the tilt axis controls (for example, from PTZ controls), thereby allowing the view to tilt uninterrupted in the same direction past the auto-pivoting point.Type: GrantFiled: September 27, 2005Date of Patent: October 14, 2014Assignee: Grandeye, Ltd.Inventors: Mark Kenneth Davey, Marcus de Ferranti, Bartu Ahiska

Patent number: 8405732Abstract: A system for automatically expanding the zoom capability of a wide-angle video camera using images from multiple camera locations. One preferred embodiment achieves this using images from the wide-angle video camera that are analyzed to identify regions of interest (RoI). Pan-Tilt-Zoom (PTZ) controls are then sent to aim slave cameras toward the RoI. Processing circuitry is then used to replace the RoI from the wide-angle images with the higher-resolution images from one of the slave cameras. In addition, motion-detecting software can be utilized to automatically detect, track, and/or zoom in on moving objects.Type: GrantFiled: June 17, 2011Date of Patent: March 26, 2013Assignee: Grandeye, Ltd.Inventors: Bartu Ahiska, Mark Kenneth Davey, Ahmet Enis Cetin

Patent number: 8145007Abstract: A system and method for providing privacy regions in a picture or video. In one example embodiment, a camera is provided which has a lens system and detector, image processing circuitry, compression and formatting circuitry, and control circuitry. Images or video taken from the camera are preferably corrected for distortion (such as that introduced by an anamorphic lens system) and sent to an operator's workstation, where a privacy region is defined. The privacy region is merged with the rest of the image, whether constant or dynamic, and displayed. Other processing, such as object tracking and alarms, can also be implemented at varying points in the process.Type: GrantFiled: April 15, 2008Date of Patent: March 27, 2012Assignee: Grandeye, Ltd.Inventors: Mark Kenneth Davey, Andrea Elvis Castellari, Yavuz Ahiska

Patent number: 8139896Abstract: A method and a system for tracking the motion of moving objects accurately on the entirety of a wide-angle video is disclosed. The method includes using a non-uniform scaling to selectively enhance pixel density, preferably in preparation for other image processing. In preferred embodiments, the further image processing (such as motion detection, object recognition, or tracking, etc.) functions better with the enhanced pixel density or distribution.Type: GrantFiled: March 28, 2006Date of Patent: March 20, 2012Assignee: Grandeye, Ltd.Inventors: Yavuz Ahiska, Andrea Elvis Castellari, Mark Kenneth Davey

One preferred embodiment achieves this using images from the wide-angle video camera that are analyzed to identify regions of interest (RoI). Pan-Tilt-Zoom (PTZ) controls are then sent to aim slave cameras toward the RoI. Processing circuitry is then used to replace the RoI from the wide-angle images with the higher-resolution images from one of the slave cameras. In addition, motion-detecting software can be utilized to automatically detect, track, and/or zoom in on moving objects.Type: ApplicationFiled: June 17, 2011Publication date: February 16, 2012Applicant: GRANDEYE, LTD.Inventors: Bartu Ahiska, Mark Kenneth Davey, Ahmet Enis Cetin

Patent number: 7893985Abstract: The present inventions provide a system and method for a wide angle camera capable of high resolution peripheral vision. A wide angle lens system distorts the image and conveys it to an image sensor, which converts the image to an electronic signal and conveys it to image processing circuitry. The image processing circuitry corrects the distortion or transforms it to human recognizable image forms. In preferred embodiments, the distortion provides greater resolution of regions of interest and more efficient use of the area of the image sensor.Type: GrantFiled: March 15, 2005Date of Patent: February 22, 2011Assignee: Grandeye Ltd.Inventors: Yavuz Ahiska, Mark Kenneth Davey, Michael Benjamin Kirsch

Patent number: 7894531Abstract: A system and method for varying the level of detail encoded in a video. In a preferred embodiment, some regions of a wide-angle video scene are encoded in an almost lossless manner, while other regions are encoded with less detail. Regions of interest can be determined in many ways, including a priori, automatically in real time, or by the selection of human operators.Type: GrantFiled: February 15, 2006Date of Patent: February 22, 2011Assignee: Grandeye Ltd.Inventors: Ahmet Enis Cetin, Mark Kenneth Davey, Halil I.
