  • Patent number: 8761256
    Abstract: An encoding apparatus having a direct mode as a prediction mode, when a pixel with opposite parity from a top field to a bottom field, for example, is referred to for obtaining a reference vector in the direct mode, performs correction by adding or subtracting a value corresponding to a half pixel to or from a value of the obtained reference vector. The encoding apparatus, when a pixel with opposite parity is referred to for obtaining a first and a second direct vector by temporally scaling the corrected reference vector, performs correction by adding or subtracting a value corresponding to a half pixel to or from values of the obtained direct vectors.

  • Publication number: 20140092966
    Abstract: A video encoding apparatus appends decoding delay and display delay correction information to encoded video data in order to ensure that even when one or more pictures that are later in encoding order than a starting encoded picture in a video data stream to be spliced to a trailing end of another encoded video data stream have been discarded from among pictures contained in the video data stream, the starting encoded picture and its subsequent pictures can be continuously decoded and displayed by a video decoding apparatus. The correction information is calculated based on a decoding interval between each discarded picture and a picture that immediately precedes the discarded picture. The video decoding apparatus corrects the decoding delay and display delay of the starting encoded picture and its subsequent pictures by using the calculated correction information.

  • Publication number: 20130148081
    Abstract: A stimulus is presented at a predetermined position of a visual field coordinate system set on a visual field dome (118). When measuring the visual field of an eye under examination, quantitative information of a three-dimensional retinal layer structure is acquired that is obtained by means for detecting a range of disappearance of a peak in the reflectance distribution of the retina obtained by a retinal OCT scan. The position of the fovea of the fundus is identified from the three-dimensional retinal layer structure. From the positional relationship with the identified fovea, it is identified to which position in a two-dimensional fundus image the range of disappearance of the peak corresponds. The position corresponding to the range where the peak disappears is marked on the two-dimensional fundus image, and the marked region is detected.
