  • Patent number: 10939096
    Abstract: Systems and methods are described for control-point based intra mode for coding a video bitstream. In an exemplary embodiment, at least two control points in a picture are selected. The control points may be, for example, points at or adjacent to two or more corners of a current block. For each of the control points, an associated intra prediction direction is identified. The intra prediction directions may be encoded in the bitstream, e.g. using differential coding. A derived intra prediction direction is interpolated based on a position of a pixel (or of a block) relative to the control points, and the derived intra prediction direction is used to predict one or more samples in the video. Different interpolation techniques, such as triangular interpolation or bilinear interpolation may be used.

  • Patent number: 10933812
    Abstract: An outside-vehicle environment monitoring apparatus includes: imaging devices including center, right, and left imaging devices; a controller; and display devices including center, right, and left display devices. The imaging devices respectively capture images of environments present in a center rear direction, a right rear direction, and a left rear direction from the vehicle. The controller acquires captured images and output display images based on the captured images. The display devices are arranged side by side within a visual range of an occupant. The center display device is disposed between the right and left display devices at a visible distance from the occupant different from the visible distance to the right display device and the visible distance to the left display device. The center display image displayed between the right and left display devices is visually perceived as having a depth relative to the right and left display devices.

  • Patent number: 10904577
    Abstract: A video compression system includes a video encoder and a bitstream processing circuit. The video encoder is hardware that performs hardware video encoding upon frames to generate a first bitstream. The first bitstream is output from an entropy encoding circuit of the video encoder. The bitstream processing circuit performs a bitstream post-processing operation upon the first bitstream to produce a second bitstream that is different from the first bitstream, and outputs the second bitstream as a compression output of the frames.

  • Patent number: 10884226
    Abstract: The invention relates to a method for scanning microscopy wherein a specimen is scanned simultaneously with a plurality of illumination spots of an excitation light. The light emitted by one specimen location irradiated with one illumination spot is detected independently of the light emitted by another specimen location illuminated with another illumination spot. A microscopic image of the specimen can be compiled from the emitted light detected for the different specimen locations. The method provides that the intensities of the different illumination spots are set independently of one another, and in that the illumination spots are guided over the specimen one after another in a scan line. The invention additionally relates to a scanning microscope.

  • Patent number: 10883822
    Abstract: Using the same image sensor to capture both a two-dimensional (2D) image of a three-dimensional (3D) object and 3D depth measurements for the object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor generates a multi-bit output in the 2D mode and a binary output in the 3D mode to generate timestamps. Strong ambient light is rejected by switching the image sensor to a 3D logarithmic mode from a 3D linear mode.

  • Patent number: 10887662
    Abstract: Methods and systems for compression that maintains parameters related to uncompressed video (PRTUV) while changing video compression ratios on-the-fly. One embodiment of a system includes: A video transmitter that receives incoming high-definition uncompressed video (HD-UV) characterized by certain PRTUV. The video transmitter compresses the incoming HD-UV into a first compressed video of ratio between 1:1 and 5:1, and sends it over a communication link to a receiver that decompresses the video to an outgoing HD-UV. When the video transmitter receives a command to smoothly change on-the-fly the compression to a second compressed video of ratio between 2:1 and 10:1, it makes the change without interrupting the continuous flow of the incoming HD-UV. Wherein the outgoing HD-UV maintains the PRTUV before, during, and after the change from the first compressed video to the second compressed video.

  • Patent number: 10827187
    Abstract: A further coding efficiency increase may be achieved if for a current block of a picture, for which the bit stream signals one of supported partitioning patterns, a reversal of the partitioning by block merging is avoided. In particular, if the signaled one of the supported partitioning patterns specifies a subdivision of the block into two or more further blocks, a removal of certain coding parameter candidates for all further blocks, except a first further block of the further blocks in a coding order, is performed. Particularly, those coding parameter candidates are removed from the set of coding parameter candidates for the respective further block, the coding parameters of which are the same as coding parameters associated with any of the further blocks which, when being merged with the respective further block, would result in one of the supported partitioning pattern. This avoids redundancy between partitioning coding and merging coding.

  • Patent number: 10812806
    Abstract: A method and apparatus of Inter/Intra prediction for a chroma component performed by a video encoder or video decoder are disclosed. According to this method, a current chroma prediction block (e.g. a prediction unit, PU) is divided into multiple chroma prediction sub-blocks (e.g. sub-PUs). A corresponding luma prediction block is identified for each chroma prediction sub-block. A chroma prediction mode for each chroma prediction sub-block is determined from a luma prediction mode associated with the corresponding luma prediction block. A local chroma predictor for the current chroma prediction block is generated by applying a prediction process to the multiple chroma prediction sub-blocks using respective chroma prediction modes. In other words, the prediction process is applied at the chroma prediction sub-block level. After the local chroma predictor is derived, a coding block associated with the current chroma prediction block is encoded or decoded using information comprising the local chroma predictor.
