  • Publication number: 20140226712
    Abstract: The present technique relates to an image processing device and method capable of performing an encoding process or a decoding process on an image at high speed. Similarly, arithmetic coding parameters arranged together in the syntax are subjected to a variable length (fixed length) decoding process together. Similarly, arithmetic coding parameters arranged together in the syntax are subjected to an arithmetic decoding process together. Accordingly, since the alternations of firmware and hardware are performed together, it is possible to improve the processing efficiency of decoding. As a result, it is possible to perform the process at high speed. The present disclosure can be applied to image processing devices, for example.

  • Publication number: 20140226714
    Abstract: A decoding method decodes a bit stream in an image decoding apparatus. The method includes receiving a weight parameter that is added to a luma quantization parameter as the bit stream. The method also includes decoding, in a decoding unit in the image decoding apparatus, the bit stream, and generating a luma component of quantized coefficients and a chroma component of quantized coefficients. Further, the method includes performing, in a dequantization unit in the image decoding apparatus, dequantization on the luma component of quantized coefficients using the luma quantization parameter and the chroma component of quantized coefficients using a chroma quantization parameter calculated on the basis of the luma quantization parameter weighted by an add operation of the weight parameter. In addition, the method includes performing, in a transform unit in the image decoding apparatus, an inverse orthogonal transform.

  • Patent number: 8791946
    Abstract: For generating a destination image (a left-eye image) from an original image and a height map thereof, the height of the height map of the original image is compared with the height of the height map of the destination image, and if a pixel of the original image is higher, the pixel of the original image is copied to a pixel of the destination image. After the pixel of the original image is copied to the pixel of the destination image, the height of the pixel of the original image is decremented. The pixel of the original image is copied in the rightward direction to pixels of the destination image until the height of the pixel of the original image becomes 0 or until a height of the pixel of the destination image becomes lower than that of the pixel of the original image. The same processes are performed on each pixel of the original image, and thereby the left-eye image is generated.

  • Patent number: 8787691
    Abstract: Encoding efficiency of image prediction encoding can be improved by performing horizontal packing as horizontal processing to manipulate a horizontal-direction array of pixels of each of a first thinned-out image and a second thinned-out image arrayed in checkerboard fashion, obtained by thinning out the pixels of each of a first image and a second image different from the first image every other line in an oblique direction, wherein pixels of first and second thinned-out images are packed in the horizontal direction. A combined image can be generated, which is combined by adjacently arraying the post-horizontal processing first and second thinned-out images after horizontal processing, as an image to serve as the object of prediction encoding. Aspects of this disclosure can be applied to a case of performing prediction encoding on a first and second image, such as a left and right images making up a 3D image.

  • Patent number: 8774277
    Abstract: An image processing method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes detecting a condition that a reference field has a different parity from a current field and that the number of chroma pixels is vertically different from the number of luma pixels. The method further includes shifting a phase of the chroma signal in the reference field in a vertical minus direction according and a value of a motion vector in a vertical direction under the detected condition so that the reference field will coincide in phase of the chroma signal with a current field. The method also includes performing a motion compensation of the decoded image signal using the reference field.

  • Patent number: 8767837
    Abstract: The present invention relates to an encoding device and a method, a decoding device and a method, an editing device and a method, a storage medium, and a program which can perform encoding and decoding so that buffer failure does not occur. Information, such as a minimum bit rate, a minimum buffer size, and a minimum initial delay time, is contained in a random access point header contained in an accessible point in a bitstream. A bitstream analyzing unit 72 analyzes an input bitstream, sets the above-mentioned information, and outputs the resulting information to a buffer-information adding unit 73. The buffer-information adding unit 73 adds the input information to the input bitstream and outputs the resulting bitstream. The present invention is applicable to an encoding device and a decoding device which process bitstreams.

  • Publication number: 20140153649
    Abstract: An encoding apparatus and an encoding method, a decoding apparatus and a decoding method, a recording medium, and a program suitable for encoding image signals with a higher compression ratio for transmission or accumulation. In an arithmetic coding section, from among the syntax elements of input image compression information, the frame/field flag is first encoded by a frame/field flag context model. When the macroblock to be processed is subjected to frame-based encoding, a frame-based context model, specified in the current H.26L standard, is applied. On the other hand, when the macroblock to be processed is subjected to field-based encoding, a field-based context model is applied for the syntax elements described below. The present invention is applied to an encoder for encoding image information and a decoder for decoding image information.
