  • Patent number: 9509940
    Abstract: According to one embodiment, an image output device includes a buffer into which video information input in stream data is written per block, a determination unit configured to determine whether the buffer is in an overflow state due to slow reproduction, and a buffering control unit configured to switch a buffering pattern of the video information based on a determination result of the determination unit.

  • Publication number: 20160267888
    Abstract: According to one embodiment, an image processing apparatus includes an encoding unit that compresses an input image for each pixel block having a size smaller than a line to generate a plurality of compressed blocks, and store the compressed blocks in a frame buffer, a reading unit that identifies an object block to be expanded among the compressedblocks, and reads the object block from the frame buffer, a decoding unit that expands the object block to generate an expanded block, and an information acquiring unit that acquires, based on the expanded block, position information used by the reading unit to identify the block to be expanded, or decode information used by the decoding unit to expand another compressed block.

  • Publication number: 20140376628
    Abstract: According to an embodiment, a multi-view image encoding device encodes a multi-view image including a plurality of viewpoint images. The device includes an assignor, a predictor, a subtractor, and an encoder. The assignor assigns reference image numbers to the reference images according to a number of reference images used in predicting already-encoded blocks obtained by dividing the viewpoint images. The predictor generates a prediction image with respect to an encoding target block obtained by dividing the viewpoint images by referring to the reference images. The subtractor calculates a residual error between an encoding target image and the prediction image. The encoder encodes: a coefficient of transformation which is obtained by performing orthogonal transformation and quantization with respect to the residual error; and the reference image numbers of the reference images used in generating the prediction image.

  • Publication number: 20140132713
    Abstract: According to an embodiment, an image encoding device includes a setting unit and an obtaining unit. The setting unit sets an corresponding block corresponding to a target block to be encoded in a first parallax image at a first viewpoint on the basis of first depth information of the first parallax image and a positional relationship between the first viewpoint and a second viewpoint of each of one or more second parallax images, sets a shared block in a search area including the target block and area adjacent to the corresponding block, and generates specifying information that indicates a positional relationship between the shared block and the corresponding block. The corresponding block is in the one or more second parallax images. Encoding information of the shared block is shared. The obtaining unit obtains the encoding information on the basis of the specifying information.
