<P>PROBLEM TO BE SOLVED: To provide a moving object detecting method and a moving object detecting device capable of detecting a moving object (vehicle, etc.), with accuracy even at night or the like with a small quantity of light. <P>SOLUTION: A detection area is photographed in a first time interval, and a photographed image is obtained and stored. The photographed image is composed of a plurality of regions, and each of the regions has brightness data of the each region. A part where the area of a group of regions with brightness that is prescribed brightness or more in the photographed image is detected to be a moving object. In other words, a photographed binarized image (i) obtained by dividing each region of the photographed image (i) at a point of time (i) into two types of regions: one region has the prescribed brightness or more and the other region has brightness being less than the prescribed brightness is calculated. A moving object image (i) corresponding to the point of time (i) is calculated on the basis of the calculated, photographed and binarized image (i) and the photographed image (i). The moving object is detected on the basis of information of the calculated moving object image (i). <P>COPYRIGHT: (C)2003,JPO |
