1. A vehicle monitoring method comprising the steps of:

  • performing recognition processing of a specific character pattern of a vehicle by extracting a specific character pattern area from a taken image data in order to monitor the vehicle based on a recognized character pattern;

    determining, when a result of the recognition processing indicates that the specific character pattern cannot be recognized, a compression range as being a vehicle area clipped from the taken image data, wherein image data of the clipped area is compressed at a predetermined low compression ratio to store or transmit the compressed image data;

    determining, when the result indicates that the specific character pattern is partially recognized, the compression range as being the specific character pattern area clipped from the taken image data, wherein image data of the clipped area is compressed at the low compression ratio to store or transmit the compressed image data; and

    determining, when the result indicates that the specific character pattern is fully recognized, the compression range as being the specific character pattern area from the taken image data, wherein image data of the clipped area is compressed at a predetermined high compression ratio to store or transmit the compressed image data.
