Claims (10)

画像に応じたアスペクト比を算出し、
前記アスペクト比から、前記画像が特定画像の可能性があるか判定し、
前記画像が特定画像の可能性がある場合、前記画像に対し電子透かし判定を行うことを特徴とする画像処理方法。Calculate the aspect ratio according to the image,
From the aspect ratio, determine whether the image may be a specific image,
When the image has a possibility of being a specific image, an electronic watermark determination is performed on the image. 前記画像は読取装置により読み取られたものであることを特徴とする請求項１項記載の画像処理方法。2. The method according to claim 1, wherein the image is read by a reading device. 前記読取装置により読み取られた画像に対し、陰影の検出もしくはマージン検出から、特定画像領域候補を決定することを特徴とする請求項１項記載の画像処理方法。2. The image processing method according to claim 1, wherein a specific image area candidate is determined for the image read by the reading device by detecting a shadow or detecting a margin. さらに、前記陰影もしくはマージン検出結果決まる領域がほぼ矩形である場合、前記特定画像領域候補とすることを特徴とする請求項３項記載の画像処理方法。4. The image processing method according to claim 3, wherein when the area determined by the shadow or margin detection result is substantially rectangular, the specific image area candidate is used. 前記アスペクト比は前記画像中の前記特定画像領域候補に対して算出されることを特徴とする請求項３項記載の画像処理方法。The image processing method according to claim 3, wherein the aspect ratio is calculated for the specific image area candidate in the image. 前記特定画像の判定は、ソフトウエア処理で実現されることを特徴とする請求項１項記載の画像処理方法。The image processing method according to claim 1, wherein the determination of the specific image is realized by software processing. 前記特定画像領域候補がない場合、前記アスペクト比算出、電子透かし判定は行われないことを特徴とする請求項５項記載の画像処理方法。6. The image processing method according to claim 5, wherein the aspect ratio calculation and the digital watermark determination are not performed when the specific image area candidate does not exist. 前記電子すかし判定の結果、前記特定画像であると判定されると、印刷禁止や異常印刷、警告表示のすくなくともいずれかがおこなわれることを特徴とする請求項１項記載の画像処理方法。2. The image processing method according to claim 1, wherein if it is determined as the specific image as a result of the electronic watermark determination, at least one of printing prohibition, abnormal printing, and warning display is performed. 請求項１項〜８項記載の画像処理方法を行う画像処理装置。An image processing apparatus for performing the image processing method according to claim 1. 請求項１〜８項記載の画像処理方法を行うためのコードが記憶された記憶媒体。A storage medium storing a code for performing the image processing method according to claim 1.
