Patent number: 8743198Abstract: A method for detecting occupancy status of a plurality of conference rooms in real time is provided. The method enables, firstly, monitoring a first output signal of a first sensor. Secondly, the method enables monitoring a second output signal of a second sensor. The method further enables comparing the first and second output signals with one or more predetermined thresholds within a predetermined time. Furthermore, the method enables correlating the comparison results to identify any uncertainty in detecting the occupancy. Furthermore, the method enables processing output from one or more image and/or video sensors based on the correlation to obtain occupancy status information when there is uncertainty in detecting occupancy. Finally, the method enables displaying the occupancy status information on one or more user devices.Type: GrantFiled: March 1, 2010Date of Patent: June 3, 2014Assignee: Infosys LimitedInventors: Kumar Padmanabh, Sanjoy Paul

Patent number: 8723918Abstract: An image capturing apparatus includes a driving unit for displacing one of a lens unit and an imaging device with respect to an optical axis, and a controller for causing the driving unit to displace one of the lens unit and the imaging device, in response to the motion of the image capturing apparatus. When, with a shooting direction being moved, captured images are generated so that a panoramic image is generated from the captured images, the controller displaces the position of the lens unit or the imaging device at the start of exposure of each image to be captured in a direction based on a direction in which the shooting direction is moved. In addition, a displacement amount at the start of the exposure is set in response to the length of an exposure time period so that the displacement during the exposure time period becomes small and the quality of an image is improved.Type: GrantFiled: December 8, 2010Date of Patent: May 13, 2014Assignee: Sony CorporationInventor: Junji Shimada

Patent number: 8718145Abstract: A relative quality score is provided that takes into account properties of an encoded version of a source video. For example, one such quality score calculates a difference of higher and lower quality transcoded versions of the source video, and computes quality metrics for each to evaluate how similar the transcoded versions are to the source video. A relative quality score quantifying the quality improvement of the high-quality version over the low-quality version is computed. The relative quality score is adjusted based on a measurement of the quality of the source video. If the relative quality score for the video indicates a sufficient quality improvement of the high-quality version over the low-quality version, various actions are taken, such as retaining the high-quality version, and making the high-quality version available to users, e.g. via a video viewing user interface.Type: GrantFiled: August 24, 2009Date of Patent: May 6, 2014Assignee: Google Inc.Inventors: Huiseng Wang, Xiaoquan Yi

Patent number: 8670029Abstract: A depth camera illuminator with a superluminescent light-emitting diode (SLED) in a motion tracking system. One or more SLEDs have a sufficient power, such as 75-200 milliwatts, to extend in a field of view in an area such as a room in a home. To correct for chromatic aberration which would otherwise exist due to the wider range of wavelengths which are emitted by an SLED compared to a laser, an achromatic diffractive optical element is used to disperse the light over the field of view. The achromatic diffractive optical element can have a stepped multi-level profile with three or more levels, or a continuous profile. Based on a tracked movement of a human target, an input is provided to an application in a motion tracking system, and the application performs a corresponding action such as updating a position of an on-screen avatar.Type: GrantFiled: June 16, 2010Date of Patent: March 11, 2014Assignee: Microsoft CorporationInventor: Scott McEldowney

Patent number: 8462208Abstract: System and method for tridimensional cartography of a structural surface. Two wires are extended in front and along the structural surface so as to define a reference surface. A measuring unit comprising a laser arrangement and a camera is moved in front of the structural surface so as to progressively scan the surface. Tow distinct light planes directed toward the structural surface are projected by means of the laser arrangement. Images of the structural surface containing lines resulting from an intersection of the light planes with the structural surface and four reference points resulting from an intersection of the light planes with the wires are captured by means of the camera. The images are processed to determine the 3D coordinates of the lines defining the mapping in a reference system bound to the reference surface considering the position and the orientation of the measuring unit based on the reference points.Type: GrantFiled: October 8, 2008Date of Patent: June 11, 2013Assignee: Hydro-QuebecInventors: François Mirallès, Régis Houde, Julien Beaudry, Bruce Hazel, Jean Cöté, Michel Blain, Serge Sarraillon
