Data synchronous reproduction apparatus, data synchronous reproduction method, and data synchronization control program

摘要

A data synchronous reproduction apparatus capable of synchronously reproducing image frames and numerical data at high speed, including: a data storage section configured to store image data including multiple image frames of monitored objects captured by cameras, and process data including multiple numerical data acquired from the monitored objects in time series; a program storage section configured to store a data synchronous control program configured to reproduce the image data and synchronously reproduce the image data and the process data on the basis of frame numbers and a frame period of the image frames and a sampling interval or record numbers of the numerical data; and a CPU configured to execute the data synchronous control program.

1. A data synchronous reproduction apparatus comprising:
an image data storage section configured to store a plurality of image frames on which a monitored object is captured by a camera, together with a frame period of the image frames, as image data with frame numbers assigned to the image frames in time series; a process data storage section configured to store data acquired from the monitored object and including a temporal change, and an elapsed time from a reference time point, collectively as process data; an image data reproducer configured to output and reproduce the image data, stored in the image data storage section, on a monitor, and to output the frame number of the image frame to be reproduced; and a data synchronous reproduction controller configured to calculate a relative time, from a first frame, of the image frame corresponding to the frame number outputted from the image data reproducer and to reproduce the image data on the monitor on the basis of the calculated relative time from the first frame.
