  • Patent number: 9955171
    Abstract: A prediction set determining section selects a prediction set from a prediction set group including a plurality of prediction sets having different combinations of prediction modes corresponding to different prediction directions. Further, a prediction mode determining section selects a prediction mode from the prediction set thus selected. An entropy encoding section encodes the prediction set thus selected, the prediction mode thus selected, and residual data between an input image and a predicted image formed on the basis of the prediction set and the prediction mode. This allows an image encoding device to carry out predictions from more various angles, thereby improving prediction efficiency.

  • Patent number: 9955127
    Abstract: Full-color images of low-light scenes are generated by the systems and methods described herein using only two light channels. An array of photosensitive pixels includes two sets of pixels, the first sensitive only to light associated with a first light channel, the second only to light associated with a second light channel. Thus the first set of pixels generate a first set of electrical signals in response to incident light within the first light channel, and the second set of pixels generate a second set of electrical signals in response to incident light within the second light channel. An image processor receives the first and second sets of electrical signals and generates a full-color image of the scene by processing only signals generated by the first and second sets of pixels.

  • Patent number: 9872045
    Abstract: A method, electronic device, computer program product, system and circuit assembly are provided for allocating one or more redundant pictures by taking into consideration the information content of the primary pictures, with which the redundant pictures would be associated. In particular, primary pictures that are determined to be more sensitive to transmission loss or corruption may be allocated one or more redundant pictures, while those that are less sensitive may not be so allocated. By selectively allocating redundant pictures to only those primary pictures that are more sensitive, the method disclosed reduces the amount of overhead associated with redundant pictures and increases the coding efficiency, without sacrificing the integrity of the video data.

  • Patent number: 9843820
    Abstract: A method and apparatus for three-dimensional video coding or multi-view video coding are disclosed. Embodiments according to the present invention derive a unified disparity vector from depth information for Inter mode and Skip/Direct mode. The unified disparity vector is derived from a subset of depth samples in an associated depth block corresponding to the current block using a unified derivation method. The unified derivation method is applied in Inter mode, Skip mode, or Direct mode when a disparity vector derived from depth data is required for encoding or decoding. The unified disparity vector can also be applied to derive a disparity vector for locating a corresponding block, and thus an inter-view motion vector candidate can be determined for Skip mode or Direct mode.

  • Patent number: 9819959
    Abstract: A method for three-dimensional or multi-view video coding receives input data associated with a current block of a current picture in a current dependent view, wherein the current block is inter-time coded based on an inter-time reference block located by a motion vector (MV), determines estimated DV (disparity vector) candidates from neighboring DVs, applies an evaluation function to the estimated DV candidates to obtain evaluation results for the estimated DV candidates, and selects a final estimated DV. The method then determines an inter-view reference region in an inter-view reference picture, determines first pseudo residues, wherein the first pseudo residues correspond to first differences between the inter-view reference region and a pseudo reference region in a pseudo reference picture located by the MV, and applies encoding or decoding to the input data associated with residues of the current block utilizing the first pseudo residues.
