  • Patent number: 10250809
    Abstract: A system and method for stabilizing video using a census kernel having test points. A subset form a connected circle centered on the kernel's center point. For each candidate pixel, a signature is calculated based on the relative brightness of the candidate pixel and of the pixels corresponding to test points when the kernel overlays the image with the center point over the candidate pixel. A candidate pixel is designated to be a corner pixel by processing the signature to determine that the candidate pixel is significantly brighter or darker than the test point pixels. For each corner pixel, a corresponding pixel in the previous frame is identified by comparing the signature of the corner pixel with signatures of pixels in the previous frame, and a corresponding motion vector is established. A motion model is calculated based on the motion vectors and applied to the digital frame.

  • Patent number: 9979889
    Abstract: Techniques to improve a digital image capture device's ability to stabilize a video stream are presented. According to some embodiments, improved stabilization of captured video frames is provided by intelligently harnessing the complementary effects of both optical image stabilization (OIS) and electronic image stabilization (EIS). In particular, OIS may be used to remove intra-frame motion blur that is typically lower in amplitude and dominates with longer integration times, while EIS may be used to remove residual unwanted frame-to-frame motion that is typically larger in amplitude. The techniques disclosed herein may also leverage information provided from the image capture device's OIS system to perform improved motion blur-aware video stabilization strength modulation, which permits better video stabilization performance in low light conditions, where integration times tend to be longer, thus leading to a greater amount of motion blurring in the output stabilized video.

A requestor subsequently requests real-time access to the surveillance video (e.g., as a result of an alarm), and if the pre-specified automatically detectable condition is met, access is automatically granted, i.e., without the need for manual intervention. An automatically detectable condition could, e.g., be an alarm condition detected by a sensor at the site of the video surveillance. Alternatively, it could be a locational proximity of the requestor to the site of the video surveillance. Alternatively, it could be a previously defined time interval.

  • Patent number: 8854482
    Abstract: A digital camera system has integrated accelerometers for determining static and dynamic accelerations of the digital cameral system. Data relating to static and dynamic accelerations are stored with recorded image data for further processing, such as for correcting image data for roll, pitch and vibrations and for displaying recorded images with a predetermined orientation using information about, e.g., roll. Data may also be used on-the-fly for smear suppression caused by vibrations.

  • Patent number: 8848979
    Abstract: Determination whether a moving object appearing in input video is an object tracked and captured by a cameraman is enabled. It is determined that a moving object is a subject image to which a cameraman pays attention based on a time difference between time when a movement state determined by a motion vector of the moving object changes and time when a shooting state determined by a motion vector of a camera motion changes.

    Abstract: Various aspects of a device and a method for processing video content may comprise one or more processors. The one or more processors may determine, in run-time, a first set of pixel sensors of one or more image sensors that capture a first video content when the device is in a first orientation relative to a reference orientation. The one or more processors may determine a change in orientation of the device from the first orientation to a second orientation relative to the reference orientation. The second orientation is different from the first orientation. The one or more processors may determine, in run-time, a second set of pixel sensors of the one or more image sensors that capture a second video content when the device is in the second orientation. An orientation of the captured second video content is same as an orientation of the captured first video content.

  • Patent number: 8810662
    Abstract: In an image processing system, a portable terminal obtains positional information and orientation information of the portable terminal and transmits these to an information processing apparatus. An image processing apparatus generates information specifying a process executable by the apparatus itself at the present moment and transmits the generated information to the information processing apparatus. The information processing apparatus stores positional information and functional information for specifying a process to be executed, for each image processing apparatus. Upon receiving the positional information and orientation information from the portable terminal, the information processing apparatus transmits, to the portable terminal, the functional information for specifying a process to be executed by a specific image processing apparatus associated with the received information.

  • Patent number: 8792009
    Abstract: An image pickup apparatus capable of reducing camera-shake blur and rolling-caused distortion of image data obtained by shooting without including invalid data. An object obtained by shooting is stored in a memory area as first image data, and data having a smaller data size than the first image data is acquired as second image data by clipping from the memory area. A clipping position which enables correction of camera-shake blur is calculated according to an amount of movement due to a camera shake. Range information indicative of a range in the memory area and shift amounts used for correcting rolling-caused distortion are calculated. Rolling-caused distortion of the second image data is corrected based on the calculated shift amounts.

    Abstract: A first heat radiation unit is formed on one surface of the imaging unit in a vertical direction. A second heat radiation unit is formed on the other surface of the imaging unit in the vertical direction. A third heat radiation unit is formed on a surface opposite to an imaging direction of the imaging unit. A first heat transfer unit transfers heat of a first heat source of the imaging unit to the first heat radiation unit and the third heat radiation unit. A second heat transfer unit transfers heat of a second heat source of the imaging unit, which has a higher maximum allowable temperature than the first heating unit, to the second heat radiation unit. A heat insulation unit suppresses heat transfer between the first and the second heat radiation units and between the third and the second heat radiation units.
