A processing apparatus includes: an acquisition unit that acquires a plurality of pieces of frame data captured simultaneously from a plurality of pieces of video data captured while parts of capturing regions are superimposed; a specification unit that specifies a blend region which includes a pixel forming a seam line connecting the plurality of pieces of frame data and is provided in a direction in which the plurality of pieces of frame data overlap; and an output unit that outputs connected frame data Fin which each pixel of the blend region has a pixel value obtained by blending pixel values of the plurality of pieces of frame data, and the plurality of pieces of frame data are connected by the seam line.

Processing apparatus, processing method and program

Objects are tracked in real time in a composed video acquired by joining a plurality of videos. A grouping candidate determining unit extracts objects present within an overlapping area, in which pieces of frame data are overlapped, among objects that have been detected and tracked in each of a plurality of pieces of frame data that were captured at the same time as candidate objects. A grouping unit arranges a plurality of candidate objects of which a degree of overlapping is equal to or larger than a predetermined threshold as a group, and an integration unit assigns integration object IDs to groups and objects that have not been grouped.

Device and method for tracking objects in composed video

To suppress an unnatural movement of a moving object at a connection point when a plurality of pieces of video data are connected to each other. A frame acquisition unitacquires pieces of frame data captured at the same time, from the pieces of video data input from cameras Cand C. A prohibited-region setting unitsets a prohibited region that is not set as a calculation target when a seam is calculated, based on a position of an object detected in an overlap region between adjacent pieces of frame data and a movement direction of the object. A seam calculation unitcalculates a seam between pieces of frame data adjacent to each other, without setting a pixel included in the prohibited region as the calculation target of seam calculation. A connection-frame output unitconnects pieces of frame data in accordance with the seam and outputs connection frame data

Image processing device, image processing method, and image processing program

To more reliably control synchronous between pieces of video/audio data from a plurality of imaging system devices. A synchronous control unitthat synchronizes a plurality of pieces of video/audio data transmitted individually from a plurality of imaging system devicesincludes a frame acquisition unitconfigured to acquire a plurality of pieces of frame data from the pieces of video/audio data and assign a frame timestamp based on an acquisition time to each of the plurality of pieces of frame data, for each of the pieces of the video/audio data, and a frame shaping unitconfigured to assign a new frame timestamp to the plurality of pieces of frame data based on a value of the frame timestamp so that start times of the plurality of pieces of frame data that are close in time among the plurality of pieces of video/audio data are equal to each other, and time intervals between the plurality of pieces of frame data are equal to each other.

Synchronous control device, synchronous control method, and synchronous control 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.

An influence on object expression performed at a transmission destination is reduced. A position information reception unitof an information integration devicereceives, regarding objects which are measured by a plurality of sensors from a plurality of locations and overlap in any of the locations, position information for each location on areas of the objects. A position information integration unitcalculates smallest rectangles or largest rectangles surrounding the objects by using the position information for each location.

Information integration method, information integration device, and information integration program

A synchronous shift of video/audio data between a plurality of display system devices is suppressed. A synchronous control device includes a coded-data adjustment unitor a video and audio data adjustment unitconfigured to perform frame adjustment based on a predetermined frame adjustment instruction by inserting predetermined frame data into a plurality of pieces of frame data in a chronological order or deleting a piece of frame data from the plurality of pieces of frame data, a video and audio data output unitconfigured to sequentially output each piece of frame data subjected to the frame adjustment, and a video and audio data output time-point adjustment unitconfigured to compare a reference time point for outputting each piece of the frame data with an output time point at which each piece of the frame data is output. In the synchronous control device, the video and audio data output time-point adjustment unitissues the frame adjustment instruction to insert predetermined frame data if the output time point precedes the reference time point by a threshold value or longer, and alternatively issues the frame adjustment instruction to delete a piece of frame data if the output time point is delayed from the reference time point by a threshold value or longer.

The present invention is to improve accuracy of position information of an object. A labeling unitof an information integration deviceassociates a label included in tracking data with an object area having a largest ratio of overlapping areas overlapping label areas included in the tracking data with regard to the object area or an object area having a largest size of overlapping areas overlapping label areas included in the tracking data, among a plurality of object areas included in a Depth map.

Matching timings of transmitting pieces of information for reproducing video and audio with presence and handling loss are provided. An information synchronization device is configured to synchronize, to a reference timestamp, data in which one or more labels for identifying respective one or more subjects on a video and one or more pieces of location information for identifying respective locations of the one or more subjects are respectively associated. The information synchronization device includes a reception unit for receiving the data at each time, a buffer for storing the received data, and a location information interpolation unit for generating, when pieces of the location information at times before and after the reference timestamp is stored into the buffer for any of the labels, location information of the label at the reference timestamp by interpolation using the pieces of the location information.
