JVC

Victor Company of Japan, Ltd , TYO: 6792, usually referred to as JVC, is a Japanese international consumer and professional electronics corporation based in Yokohama, Japan. Founded in 1927, the company is best known for introducing Japan's first televisions, and for developing the Video Home System video recorder.From 1953 to 2008, Matsushita Electric Industrial Co., Ltd. was the majority stockholder in JVC. In 2008, JVC merged with Kenwood Corporation to create JVC Kenwood Holdings. Wikipedia.


A motion vector predictor candidate generation unit derives a plurality of motion vector predictor candidates by prediction from first coded prediction blocks neighboring a prediction block subject to coding within the same picture as the prediction block subject to coding, or from a second coded prediction block located at the same position as or in the neighborhood of the prediction block subject to coding in a picture different from that of the prediction block subject to coding, and adds the derived motion vector predictor candidates in a motion vector predictor candidate. The motion vector predictor candidate generation unit determines, for the purpose of obtaining a predetermined number of motion vector predictor candidates, which of first coded prediction blocks provides the motion vector from which to derive the motion vector predictor candidate, organizing the blocks in the order of priority.


A first vector predictor candidate list generating unit generates a first motion vector predictor candidate list from motion vectors of encoded neighboring blocks to blocks to be encoded. A second vector predictor candidate list generating unit generates a second motion vector predictor candidate list from motion vectors of blocks at the same positions as the blocks to be encoded in an encoded image and neighboring blocks to the blocks at the same positions. A combination determining unit determines whether to generate a third vector predictor candidate list combining the first and second vector predictor candidate lists by comparison of a block size of the blocks to be encoded and a threshold size. A vector predictor candidate list deciding unit generates the third vector predictor candidate list from the first vector predictor candidate list.


A master camera device and a plurality of slave camera devices are directly connected through a network, and form one network segment. The master camera device performs multicast communication with each slave camera device, and acquires information representing a transmission condition from each slave camera device. In a case where a worsening transmission condition relative to a predetermined threshold is detected from a transmission condition of each slave camera device and a transmission condition of the master camera device, the master camera device performs multicast communication with each slave camera device, and controls an encoding level representing a degree of encoding process, sequentially from an encoder having a lower priority, including the encoder of the master camera device, to improve the transmission condition. Thus, by an efficient communication, the transmission condition is improved from an initial stage having an unstable transmission condition, to obtain a preferable real-time image.

An image display device includes: a light source that emits a beam having a spreading angle in a first direction and a spreading angle in a second direction, which is smaller than the spreading angle in the first direction, in a direction perpendicular to the first direction; an afocal optical system member that has a focal point and changes the beam emitted by the light source into a parallel beam; an anisotropic diffusion plate that is arranged at the focal point and that widens at least the spreading angle in the second direction; a vibration unit that vibrates the anisotropic diffusion plate; a fly-eye lens array on which the parallel beam emitted from the afocal optical system member becomes incident; an image display element that modulates the beam that has passed through the fly-eye lens array into image display light.
