A character recognition device comprising: a storage means storing a plurality of dictionary databases corresponding to each of a plurality of degradation levels, said databases being generated from images wherein an original character image has been degraded using a plurality of different degradation levels; an image input means that receives input of images; an extraction means that extracts character images from said images; a usage order determination means that determines an usage order for dictionary databases on the basis of degradation degrees for extracted character images; and a character recognition means that uses dictionary databases in accordance with said usage order, recognizes characters included in the extracted character image and, if recognition results for the character recognition fulfill prescribed conditions, outputs the recognition results without performing recognition using the dictionary database next in said usage order. As a result, accurate and fast recognition of degraded character images can be performed.

Character recognition device, character recognition method and program

A monitoring system has a plurality of monitoring terminals communicably connected to each other. Each monitoring terminal has an imaging portion for imaging a monitoring area allocated to an own-terminal, a tracing portion for processing an imaged image of the imaging portion and tracing a target person traveling in the monitoring area, a tracing information creation portion for creating tracing information associating the target person traced by the tracing portion with tracing start time, tracing stop time, and characteristic information of the target person, a tracing information storage portion for storing the tracing information created by the tracing information creation portion, and a tracing information notification portion for notifying the tracing information created by the tracing information creation portion to the other monitoring terminals.
