1. A video monitoring apparatus comprising:
- a camera picking up an image;
a video control unit generating an image in which additional information is superimposed on an image picked up by the camera;
an image output unit outputting the image generated by the video control unit; and
a database for storing a record for associating image specifying information for specifying an image picked up by the camera with the additional information,wherein the database stores a plurality of records in which a distance between images specified by image specifying information is smaller than a size of an image picked up by the camera, andthe video control unit conducts;
searching of the image specifying information in the database for one or more image specifying information each of which specifies an image having a distance from an image currently picked up by the camera falling within a prescribed range;
extraction, from the one or more image specifying information obtained as a result of the searching, of image specifying information each specifying an image fit within the image currently picked up by the camera; and
superimposing additional information corresponding to the extracted image specifying information on the image picked up by the camera.

Abstract
A video monitoring apparatus capable of efficiently superimposing additional information on a monitoring camera image is provided. The video monitoring apparatus holds image specifying information for specifying an image picked up by a camera and additional information in correspondence with each other. In superimposing additional information on an image, additional information corresponding to images having a distance therebetween falling within a prescribed range is searched for, and out of the thus found additional information, one that may be fit within an image currently picked up by the camera is superimposed on the camera image.
