  • Publication number: 20170256040
    Abstract: Method and system for image augmentation. A captured image of a user in a scene includes a user portion and a background portion with partial scene features cut off at the image frame borders. A first set of imaging parameters is obtained, including the position and orientation of the camera when capturing the image. A background-image is retrieved in accordance with the obtained imaging parameters, from a database that includes imagery of real-world environments. The retrieved background-image is captured at a second set of imaging parameters such that the background-image includes supplementary scene features located beyond the image frame borders of the captured image and supplementing information for the partial scene features of the background portion. An updated image is generated in which the user appears relative to a background that includes the supplementary scene features, by image fusion of the captured image with the background-image.

  • Patent number: 9753141
    Abstract: Active or passive gated-sensor imaging system characterized by a minimized time period between successive sensor exposures. In the active imaging system, a light source emits light pulses toward a region of interest, and an image sensor receives reflections of the pulses reflected from objects located in a DOF to be imaged and converts the reflections into an image. Each frame of the image includes a plurality of gating cycles. Each gating cycle includes the emission of a respective light pulse and the reception of reflections of the respective pulse. A delay-time (TDELAY) is defined as the duration between the sensor exposure periods of successive gating cycles. A controller controls the operation of the light source and the image sensor, to minimize the delay-time for at least one gating cycle of an image frame, where the delay-time is adaptively determined in accordance with at least one system parameter or environmental condition.
