  • Patent number: 11368623
    Abstract: Systems and methods are provided that capture and process frames of frame data. An image sensor captures frames of frame data representative of light incident upon the image sensor using a rolling shutter and outputs the frames of frame data. The image sensor captures at least one of the frames over a frame capture interval and then waits over a blanking interval before capturing another frame. A buffer receives and stores the frames output by the image sensor. An image signal processor retrieves the frames from the buffer and processes the frames over successive frame processing intervals to generate a video having a time interval per frame greater than the frame capture interval. At least one of the successive frame processing intervals is greater than the frame capture interval and is less than or equal to a sum of the frame capture interval and the blanking interval.

    Abstract: An incoming image stream may be obtained from an image capture device operating in low-light conditions and/or a simulated long exposure image capture mode. As images are obtained, a weighting operation may be performed on the pixels of the captured images to generate and/or update an accumulative weight map, wherein the weighting is based, e.g., on the proximity of the captured pixels' values to the respective image capture device's maximum observable pixel value. As batches of images are obtained, they may be fused, e.g., according to the accumulative weight map, in a memory-efficient manner that places an upper limit on the overall memory footprint of the fusion operations, to simulate an actual long exposure image capture. In some embodiments, the weight map may be stored at a lower resolution than the obtained images and then upscaled, e.g., via the use of guided filters, before being applied in the fusion operations.

  • Patent number: 10939052
    Abstract: The invention disclosed herein concerns a privacy enhancing device for use with IP cameras and related methods. The privacy device includes an adjustable light filter and is configured to be placed over the lens of an IP camera such that the image captured by the IP camera passes through the filter. The transparency of the light filter is controlled using a control module in response to user inputs received using an on-board user interface so as to provide varying levels of privacy ranging from an opaque state and a transparent state. Inputs that serve to facilitate and enhance operation of the device can also be received from other input sources such as connected computing devices. For security, the control path defined by the control module and the on-board user input device can be isolated from other more sophisticated control devices that can be prone to hacking and remote control.

  • Patent number: 10834324
    Abstract: Correcting image distortion during camera motion using a system including a processor and a camera having a rolling shutter. Multiple image frames are captured by the camera equipped with the rolling shutter. The captured image frames include a base image frame and a previous image frame. Multiple time stamps are recorded respectively for multiple corresponding image points in the previous and base image frames. For the corresponding image points, multiple ego-motions are computed responsive to the time stamps of the corresponding image points of the base image frame and the previous image frame to correct the image distortion caused by the rolling shutter.

  • Patent number: 10834315
    Abstract: An imaging apparatus having no synchronization support function by a time code and to cut down a system cost, in synchronizing respective moving images in the case of outputting and displaying moving images input from a plurality of imaging apparatuses through network transmission. A vertical synchronization signal input from a particular imaging apparatus among a plurality of imaging apparatuses is used as a reference to select frame image data items from moving image data input from the plurality of imaging apparatuses, and the selected frame image data items are integrated into a single stream and sent. Even in a case where the plurality of imaging apparatuses captures videos asynchronously, it becomes possible to select, from the respective moving images, frame images with a small imaging timing difference on the basis of the vertical synchronization signal of the particular imaging apparatus.

  • Patent number: 10832636
    Abstract: Provided is a device and a method in which an HDR image of which a setting luminance is higher than the highest allowable luminance of a display unit, can be displayed as a bright image in a bright audiovisual environment. An adjusted luminance for output is calculated by multiplying an output luminance calculated according to an input/output transfer function corresponding to an input HDR image, and a predetermined gain, together, and thus, a display image is generated. An image signal processing unit sets a reference point P to be in a position based on the highest allowable luminance of a display unit, and calculates the adjusted luminance for output by applying a gain function of setting a gain, based on the reference point P, to an input/output transfer function according to the input HDR image, and thus, generates the display image.
