MONITORING DEVICE, PRODUCTION LINE, AND CONTROL METHOD OF MONITORING DEVICE

摘要

To simplify a work for confirming a recorded moving image, without modifying a system on the side where a production line including an automatic machine is monitored.SOLUTION: Without changing a system to be monitored, and a system on the monitored side, a moving image M shot by means of a camera 21 is recorded by means of a recorder 22. For example, a moving image processing section placed in the recorder 22 detects a repetition part of the recorded original moving image (M), and divides the original moving image (M) into partial moving images in units of the detected repetition part. Detection of the repetition part is carrier out by applying a circulation detection method of Floyd to change with time of representative values from multiple still-images clipped from the original moving image, for example. The partial moving images are formed as multiple partial moving image files, or by imparting chapter data in units of the repetition part. Specific partial moving images specified by user operation are reproduced by means of a moving image reproducer.SELECTED DRAWING: Figure 2
