  • Publication number: 20170118518
    Abstract: An approach is provided for providing social interactions with programming content. The tracking platform processes and/or facilitates a processing of one or more images of one or more users watching programming content to cause, at least in part, an identification of the one or more users. Next, the tracking platform determines one or more social connections among the one or more users, one or more other users, or a combination thereof. Then, the tracking platform causes, at least in part, a transmission of status information associated with the one or more users, the one or more other users, the programming content, or a combination thereof.

  • Patent number: 9400937
    Abstract: In an example embodiment, a method, apparatus and computer program product are provided. The method includes facilitating capture of at least one image of a scene including a foreground object by at least one rolling shutter sensor. The at least one image includes a pattern in an image region of the foreground object comprising a series of alternate dark and bright pixel regions. The at least one image is captured by setting exposure time of the sensor as equal or less than a read-out time of a set of pixel rows of a plurality of pixel rows, and by facilitating a repeating sequence of ON and OFF of flash such that flash is ON while capturing the set of pixel rows, and OFF while capturing subsequent set of pixel rows. The method includes determining a contour of the foreground object in the at least one image based on the pattern.

  • Publication number: 20160189387
    Abstract: In exemplary implementations of this invention, a depth-sensing system includes multiple light sources, multiple cameras, a pattern generator and one or more computers. The system measures depth in a scene. The multiple light sources emit light that illuminates a pattern generator. The pattern generator refracts, reflects or selectively attenuates the light, to create a textured light pattern that is projected onto the scene. The multiple cameras capture images of the scene from different viewpoints, while the scene is illuminated by the textured light. One or more computers process the images and compute the depth of points in the scene, by a computation that involves stereoscopic triangulation.

  • Patent number: 9240839
    Abstract: An array of light emitters is arranged single-file along an emitting surface of a transmitting device and emits light in a z-direction normal to the emitting surface. The array of light emitters is aligned along a y-direction normal to the z-direction. A lens assembly is optically coupled to the array of light emitters. The lens assembly includes at least one cylindrical lens and at least one aspherical lens. The lens assembly emits the light in free-space along the z-direction and has a first focal length in the y-direction and a different, second focal length in an x-direction. An encoder is coupled to apply a data signal to the array of light emitters. The data signal causes the array of light emitters to illuminate in a pattern that switches at a rate corresponding to a rolling shutter of a receiving sensor array.

  • Patent number: 9131159
    Abstract: A method and apparatus for optical field communication, wherein incident light is spread on the surface of an image sensor with a diffuser element; a conventional digital image is captured with high exposure pixel rows of the image sensor; and the light intensity on two successive low exposure pixel rows of the image sensor is recorded. The recorded light intensities of the two successive low exposure pixel rows are compared; and in response to comparing the recorded light intensities of the two successive low exposure pixel rows, a value of a bit received via optical field communication is determined.

  • Publication number: 20140022402
    Abstract: A method, apparatus and computer program product of using one or more multi-media recording devices to capture audio/video records of scenes and events remotely and automatically through a recording interface. A configuration server acting as a recording interface receives conditional configuration settings from a user. Through a control function, the configuration server interface configures one or more remote media devices such as video cameras or audio recording equipment to capture a designated scene or event. If more than one device may be necessary to perform the scene capture, the interface may send assistance requests to additional media devices to acquire necessary scene coverage. The interface monitors the scene capture as it occurs and directs the multimedia data to streaming or storage as the initial configuration settings require.
