摘要:
When a prediction is made between fields with different parity, the predicative efficiency of a chrominance vector is improved by adaptively switching the generation of a chrominance motion vector depending on a encoding/decoding field parity (top/bottom) and a reference field parity (top/bottom), and the coding efficiency is improved accordingly.

A video decoding apparatus includes a reference picture list storing unit configured to store picture information of pictures; a motion vector information storing unit configured to store motion vector information including motion vectors of blocks that are spatially and temporally adjacent to a target block to be decoded and reference picture identifiers indicating pictures that the motion vectors refer to; and a vector predictor generating unit configured to scale a vector predictor candidate for a motion vector of the target block based on the picture information and the motion vector information and to correct the scaled vector predictor candidate toward 0 by a predetermined amount.

A signal transmission device, includes a computer processor, the device includes an irradiation unit configured to irradiate incoming light, which includes one or more symbols with which the incoming light has been varied in response to a signal to be transmitted, on an arbitrary object with a first intensity; and a control unit configured to control an amplitude of the first intensity on a basis of a reflectance of the incoming light irradiated on the object.

摘要:
A down-sampler samples down a signal whose low frequency component is cut to 1/2. A sign inversion unit cyclically multiplies the sampled-down high-frequency sub-band signal by a negative value and outputs a sign-inverted high-frequency sub-band signal. Thus, in the frequency characteristic of the high-frequency sub-band signal, the signal power on the low frequency side can be increased.
