A video generation device includes: an object extraction unit that extracts an object area from a captured video in a space; a spatial position tracking unit that detects an article from three-dimensional position measurement data in the space, applies identification information to the article, and calculates a three-dimensional spatial position of the article using the three-dimensional position measurement data; a position information merging unit that links the object area to the identification information of the article to associate the three-dimensional spatial position with the object area; a depth expression unit that generates a depth expression video of only the object area with which the three-dimensional spatial position has been associated, a depth of the video being able to be adjusted in the depth expression video; and a feedback unitthat transmits information indicating a method for reducing blurring generated in the object area of the depth expression video.

Video generation apparatus, method and program

A synchronous control system is provided. A transmission deviceincludes a reception unitthat receives a control signal for a lighting device in a live event site and a transmission unitthat transmits, to a reception device in a live viewing site, the control signal to which an output time is appended. The output time is obtained by adding a predetermined period of time to a receipt time at which the control signal is received. A reception deviceincludes a reception unitthat receives the control signal to which the output time is appended, and an output control unitthat outputs the control signal to a lighting devicein the live viewing site at the output time, and allows the control of the lighting deviceto synchronize with at least one of video and audio to be played in the live viewing site.

Accurate and rapid identification can be performed even when feature vectors of input pixels and background pixels are close. An image processing device includes: a feature extractor which extracts features of pixels from an input image and an input image of a different time; a quantization unit which reduces the number of gradations of features extracted by the feature extractor; a learning unitwhich learns combinations of the features of pixels through a machine learning algorithm that performs nonlinear identification and constructs a network according to machine learning; an LUT generatorwhich generates an LUT that replaces arithmetic operations of the network constructed by the learning unit; a foreground region estimatorwhich rapidly estimates similarity of each pixel of the input image to a foreground by referring to the LUT generated by the LUT generator; and a boundary correctorwhich classifies regions similar to the foreground estimated by the foreground region estimatorinto the foreground, a background, and an unclassified region including boundary pixels of the foreground and the background and performs boundary correction only on the unclassified region.
