Abstract

The present invention provided a method for reproducing a picture taken by a monitoring camera or the like, capable of obtaining relation between a preceding and following pictures. A display control section displays four frame pictures taken by one network camera on a monitor by dividing into four pictures. First, in division display D1, frame images A1 to A3 are displayed substantially at the same time. After a predetermined period, the division display D1 is replaced with division display D2. Also in this case, frame images A5 to A8 are displayed substantially at the same time. Thereafter, in the same way, the division display is switched for each predetermined period. The frame images are displayed always in the order of upper left, upper right, lower right and lower left.

Description

technical field [0001] The present invention relates to a technique for displaying images stored in an image recording system such as a monitoring system on a monitor. Background technique [0002] There is a surveillance system in which surveillance cameras are installed in facilities such as buildings and apartments, and images sent from the surveillance cameras are recorded by a recording device. The recording device is installed in a guard room in a building, a management room in an apartment, etc., and a guard or a manager can appropriately play back the video recorded in the recording device and check it with a monitor. Alternatively, images sent from each camera can be displayed and confirmed on a monitor in real time. [0003] Generally, a plurality of cameras are preliminarily installed in a facility, and images are sent from the plurality of cameras to a recording device. Furthermore, since images from a plurality of cameras can be checke...
