Since the image obtainer 1 is set outdoors, the sharpness of the captured vehicle image is greatly affected by weather and climate. If the sharpness of the vehicle image is insufficient, the subsequent determination of tampered license plates and matching of the vehicle information will be directly affected. Therefore, in order to solve the above problem, the apparatus for identifying license plate tampering of the disclosure further includes an image processor 4 to further process the vehicle image obtained by the image obtainer 1 to meet the extraction requirements. In an exemplary embodiment of the disclosure, the image processor may be implemented as an IC chip such as an image processor or video processor. However, the image processor of the disclosure is not limited thereto, but may also be any other device that can process an image.

In an exemplary embodiment of the disclosure, the image obtainer 1 is further configured to send the vehicle image to the image processor 4 when the vehicle information is unable to be extracted according to the vehicle image. The image processor 4 is configured to sharpen the vehicle image to meet the extraction requirements of the image obtainer 1, and send the sharpened vehicle image to the image obtainer 1 so that the image obtainer 1 extracts vehicle information from the sharpened vehicle image.

The vehicle image may be sharpened with the image processor 4 so that the vehicle image meet the extraction requirements of the vehicle information, thereby guaranteeing an image obtaining effect at different capturing positions and angles, of different illumination intensities and different air qualities so that the current vehicle to be determined is identified and matched more precisely while the error rate is reduced.
