  • Patent number: 6842540
    Abstract: A surveillance image is acquired from a surveillance camera. Supplement information (such as date and time, and surveillance camera number) relating to the surveillance image is acquired. By imaging the supplement information, supplement information image data is generated. A quantized discrete cosine transform coefficient block obtained by conducting discrete cosine transform and then quantization on surveillance image data of the surveillance image is added to a quantized discrete cosine transform coefficient block obtained by conducting discrete cosine transform and then quantization on the supplement information image data. A resultant sum is subjected to Huffman encoding. The result is recorded.
