An image processing apparatus that processes an image composed of a latent image area and a background area,
The latent image area is represented by a set of dots represented by a first number of pixels, and the background area is represented by a set of dots represented by a second number of pixels different from the first number of pixels. And an image generation means for generating a new image;
An image processing apparatus comprising: an adding unit that adds additional information to at least the latent image area of the image generated by the image generating unit.
前記画像生成手段は、前記第1の画素数を前記第2の画素数よりも少なくし、更に、前記潜像領域を表現する夫々のドット間の間隔を、前記背景領域を表現する夫々のドット間の間隔よりも小さくすることを特徴とする請求項1に記載の画像処理装置。  The image generating means reduces the first pixel number to be smaller than the second pixel number, and further sets an interval between each dot representing the latent image area to each dot representing the background area. The image processing apparatus according to claim 1, wherein the image processing apparatus is smaller than the interval therebetween. 前記付加手段は、前記潜像領域に含まれるドット群の夫々の位置を、前記付加情報中の第1の付加情報の対応するビット位置におけるビット値に応じて制御し、前記背景領域に含まれるドット群の夫々の位置を、前記付加情報中の第2の付加情報の対応するビット位置におけるビット値に応じて制御することを特徴とする請求項1に記載の画像処理装置。  The adding means controls the position of each dot group included in the latent image area according to the bit value at the corresponding bit position of the first additional information in the additional information, and is included in the background area. The image processing apparatus according to claim 1, wherein each position of the dot group is controlled according to a bit value at a bit position corresponding to the second additional information in the additional information. 更に、前記画像生成手段により生成した画像と文章画像との合成画像を生成する合成画像生成手段を備えることを特徴とする請求項1乃至3の何れか1項に記載の画像処理装置。  The image processing apparatus according to claim 1, further comprising a composite image generation unit that generates a composite image of the image generated by the image generation unit and a text image. 前記第1の画素数は、2つ以上の異なる画素数を示すことを特徴とする請求項1に記載の画像処理装置。  The image processing apparatus according to claim 1, wherein the first number of pixels indicates two or more different numbers of pixels. 前記第2の画素数は、2つ以上の異なる画素数を示すことを特徴とする請求項1に記載の画像処理装置。  The image processing apparatus according to claim 1, wherein the second number of pixels indicates two or more different numbers of pixels. 潜像領域と背景領域とで構成されている画像を処理する画像処理方法であって、
前記潜像領域を第1の画素数で表されるドットの集合により表現し、前記背景領域を前記第1の画素数とは異なる第2の画素数で表されるドットの集合により表現することで、新たな画像を生成する画像生成工程と、
前記画像生成工程で生成した画像のうち、少なくとも前記潜像領域に付加情報を付加する付加工程と
を備えることを特徴とする画像処理方法。
An image processing method for processing an image composed of a latent image area and a background area,
The latent image area is represented by a set of dots represented by a first number of pixels, and the background area is represented by a set of dots represented by a second number of pixels different from the first number of pixels. An image generation process for generating a new image,
An image processing method comprising: an additional step of adding additional information to at least the latent image area of the image generated in the image generation step.
コンピュータを請求項1乃至6の何れか1項に記載の画像処理装置として機能させることを特徴とするプログラム。  A program for causing a computer to function as the image processing apparatus according to any one of claims 1 to 6. 請求項8に記載のプログラムを格納することを特徴とするコンピュータ読み取り可能な記憶媒体。  A computer-readable storage medium storing the program according to claim 8.
