  • Patent number: 10051277
    Abstract: A method of palette coding to apply the palette coding to sub-blocks of a coding unit and to allow each sub-block to use an individual palette table is disclosed. If the current coding block is not partitioned, the palette coding is applied to the current coding block using a first palette. If the current coding block is partitioned into multiple sub-blocks, the palette coding is applied to each sub-block using an individual second palette. Each sub-block may correspond to one prediction unit (PU). In another embodiment of the present invention, a method is disclosed that skips update of palette predictor such as last coded palette table, last coded palette size and palette predictor size associated with the current coding block if the current palette size is smaller than or equal to palette update size.

  • Patent number: 10043359
    Abstract: A monitoring area is scanned by an area sensor device (e.g., an optical distance meter) detects objects. Moving objects are identified among the detected objects, and, among the identified moving objects, a moving object which is present in the monitoring area and which has been newest identified is set as a tracking target. The moving object which has been set at the tracking target is automatically tracked by a camera device. As a result, even if there are present a plurality of moving objects in the monitoring area, tracking targets can be switched from one to another, so that it is possible to designate, as a tracking target, a moving object desired by an observer.

  • Patent number: 10027982
    Abstract: The current application is directed to flexible methods for motion-vector-based encoding of macroblocks within video frames. The flexible methods for encoding video-frame macroblocks provide for segmentation of a video-frame block and encoding the segmented video-frame block by a segmented-block motion vector that includes a reference to a segmentation-defining region of a segmentation map and that also includes references to sources of intensity-and-color data for each segment. Segmented-block motion vectors provide for flexible segmentation-based encoding of video-frame blocks without sacrificing the coding efficiencies attendant with conventional motion-vector-based video encoding.

  • Patent number: 10017127
    Abstract: A camera having a housing, an optical system and an electrical image sensor, particularly for applications in the exterior region of motor vehicles, limits or prevents undesirable influences from moisture penetrating the camera or the housing. This is achieved by virtue of there being channels provided for air circulation in an interior of the optical system on the basis of the heating of air in the housing by operation of the image sensor, with the channels channeling air around lenses of the optical system. The channels may be along an internal wall of a lens frame of the optical system, and the channels may extend from an end portion of the lens frame at or near the image sensor to an internal space within the lens frame and between two adjacent lens elements of the optical system.

  • Patent number: 9998763
    Abstract: A system and method for transmitting compressed image data includes an encoder, responsive to received image data representing an image, for minimizing a space-spatial frequency of the image data by applying a predetermined orthogonal function thereto to generate a mathematical representation of the image data and extracting coefficients of the mathematical representation of the image data. A transmitter transmits the coefficients of the image data from a first location to a second location. A receiver receives the transmitted coefficients of the image data at the second location from the first location. A decoder recreates the mathematical representation of the image data at the second location responsive to the received coefficients and the predetermined orthogonal function and generates the image data from the recreated mathematical representation of the image data.

  • Patent number: 9986228
    Abstract: Embodiments present different images to multiple viewers of a shared display using glasses with lenses that transmit only selected images from the display. The images viewed by each of the glasses may be based on the tracked position and orientation of the glasses, so that the images correspond to the user's viewpoint. Different images may also be presented to left and right eyes for 3D stereoscopic viewing. The position and orientation of the lenses of the glasses may be tracked by analyzing images from one or more cameras observing the glasses. Glasses may have distinctive geometric shapes or features, such as circular lenses or rims, or recognizable blobs or patterns, to facilitate tracking. The lenses of the glasses may combine multiple barriers such as anaglyph filters, polarizing filters, and shutters, to select images from the display. Glasses may also be used as pointing devices to select and manipulate 3D objects.

  • Patent number: 9961364
    Abstract: An apparatus and method for temporal motion vector prediction for a current block in a picture are disclosed. In the present method, one temporal block in a first reference picture in a first list selected from a list group comprising list 0 and list 1 is determined. When the determined temporal block has at least one motion vector, a candidate set is determined based on the motion vector of the temporal block. The temporal motion vector predictor or temporal motion vector predictor candidate or temporal motion vector or temporal motion vector candidate for the current block is determined from the candidate set by checking a presence of a motion vector pointing to a reference picture in a first specific list in said at least one motion vector, wherein the first specific list is selected from the list group based on a priority order.

  • Patent number: 9955183
    Abstract: Methods of converting an open group of pictures (GOP) to a Closed GOP are described that remove backward references to the GOP prior to the GOP undergoing conversion in an Open GOP interframe-encoded video stream. Within the GOP undergoing conversion, bipredictive frames with backward references to the prior GOP are replaced with frames referring only to the I frame of the GOP undergoing conversion, which is flagged as an IDR frame. Consolidation and assembly of video clips that are encoded using Open GOP compression schemes generally result in broken interframe references between GOPs. To address this, existing methods involve significant decoding and re-encoding of edited video sequences. The described methods serve to break the backward chain of references in the encoded stream, resulting in reduced re-encoding requirements, with attendant reduced quality degradation of the edited sequence.

  • Patent number: 9942562
    Abstract: A video prediction encoding device provided with a picture storage unit storing, as reference pictures to be used for encoding of a subsequent picture, one or more of reconstructed pictures restored from compressed picture data and a memory control unit to control a frame memory in the picture storage unit. When a frame size of input pictures is not more than 1/(2^L) (where L is an integer of one or more) of a maximum frame size of pictures, the memory control unit determines that (2^L) times the maximum number of reconstructed pictures are storable in the frame memory.

  • Patent number: 9942622
    Abstract: A system synchronizes one or more media streams, such as video stream or audio streams, by embedding frame identifiers in each compressed media stream, and then by using synchronizing signals to render each frame simultaneously by referencing the embedded frame identifier. Since the frame identifier is embedded in between encoded frames of the compressed media stream without altering any of the compressed, encoded data, the frame identifier information could be rapidly embedded without creating lag associated with manipulating existing data. This technique could be used, for example, to synchronize a single HD video on a plurality of display devices (e.g. a football game on a wall of video monitors), or to synchronize a plurality of HD video streams on a single display device (e.g. a plurality of live video feeds on a single computer monitor).
