  • Patent number: 9681045
    Abstract: Systems and methods for generating a panoramic image include capturing image data from a plurality of cameras and storing the image data within a memory buffer of the respective camera; transmitting image data from an upstream camera to a downstream camera; and combining, within the downstream camera, the image data from the upstream camera with the image data of the downstream camera as combined image data. Each of the plurality of cameras may include an imaging array for capturing image data of a scene; a receiver for receiving image data from an upstream camera of the plurality of cameras; a memory buffer for: combining the image data received from the upstream camera with image data captured by the imaging array to form combined image data, and storing the combined image data; and a transmitter for transmitting the stored combined image data to a downstream camera of the plurality of camera.

  • Patent number: 9658454
    Abstract: An eyewear display system includes a camera coupled to capture an image of an object in a surrounding environment. A projector is coupled to receive the captured image to output a projected image. A polarizing beam splitter optically coupled to receive the projected image and an actual view of the surrounding environment. The polarizing beam splitter is optically coupled to output a combined view of the projected image combined with the actual view of the surrounding environment. The combined image is to be directed to an eye of a user. An intensity controller is optically coupled between the surrounding environment and the polarizing beam splitter to controlling an intensity of the actual view of the surrounding environment received by the polarizing beam splitter.

  • Publication number: 20150102993
    Abstract: A projector-camera system includes a projector coupled to back project a first image on a translucent diffusing screen. A camera is coupled to capture a second image from a back side of the translucent diffusing screen. The second image includes the first image back projected on the translucent diffusing screen and a shadow of a pointing device cast on a front side of the translucent diffusing screen. The pointing device is on the front side of the translucent diffusing screen and is in close proximity to the translucent diffusing screen. A processing block is coupled to the projector and the camera to generate a third image including the shadow of the pointing device. The processing block is further coupled to activate a command in a main computer coupled to the processing block in response to a relative position of the shadow of the pointing device in the third image.

  • Patent number: 8866913
    Abstract: Systems and methods for calibrating a 360 degree camera system include imaging reference strips, analyzing the imaged data to correct for pitch, roll, and yaw of cameras of the 360 degree camera system, and analyzing the image data to correct for zoom and shifting of the cameras. Each of the reference strips may include a bullseye component and a dots component to aid in the analyzing and correcting.

  • Publication number: 20140209815
    Abstract: A fluorescence imaging module includes an image sensor and a lens disposed between a fluorescence sample and the image sensor to focus a fluorescence image of the fluorescence sample onto the image sensor. The fluorescence sample is to be positioned an object distance away from the lens. The lens is positioned an image distance away from the image sensor. The image distance is greater than the object distance. An illuminating device is disposed between the fluorescence sample and the lens. The illuminating device includes a light source and an optical element. The light source is adapted to emit light in a first direction towards the optical element. The optical element is optically coupled to receive the light and redirect the light in a second direction towards the fluorescence sample to illuminate the fluorescence sample.

  • Patent number: 5995150
    Abstract: A method for presenting video on a local monitor and a remote monitor includes encoding an original video signal to produce a first compressed video signal. Using the first compressed video signal, the video signal is also encoded to produce a second compressed video signal. Both the first and second compressed video signals are transmitted to a local terminal at which the first and second compressed video signals are decoded to produce first and second decoded video signals. A first decoded version of the video signal is produced from a combination of the first and second decoded video signals. Only the first compressed video signal is transmitted to a remote terminal at which a second decoded version of the video signal is recovered from only the first compressed video signal.The first compressed video signal may be produced by motion compensation temporally encoding and spatially encoding the original video signal.
