Abstract

Conventionally, it is impossible to securely and efficiently implement the judgment of specific images. In order to solve this task, an image processing apparatus according to the present invention is characterized in including an input unit (in these embodiments, this corresponds to, for example, the interface unit in FIG. 1) for inputting color image data, an judging unit (this corresponds to, or example, the forgery judging unit in FIG. 1) for judging whether the judgment of whether a color image composed of the color image data is a specific image has been already performed, and an image judging unit (this corresponds to, for example, the forgery judging unit in FIG. 1) for judging whether the color image include the specific image if the judgment has not been performed yet.

Claims6

Dependent claims

An image processing apparatus, comprising:

first receiving means for receiving, from an image generating apparatus having a forgery judging function, a result of judgment by the image generating apparatus having the forgery judging function;
second receiving means for receiving color image data from any of the image generating apparatus having the forgery judging function and an image generating apparatus not having the forgery judging function, wherein if the color image data is received from the image generating apparatus having the forgery judging function, the color image data is received after receiving the result of judgment by said first receiving means;
judging means for judging whether a color image composed of the color image data received by said second receiving means is a specific image;
and
output means for outputting the color image data so as to make an image forming unit form a color image by using the color image data received from said second receiving means,
wherein said image processing apparatus controls formation of the color image according to the result of judgment in the image generating apparatus having the forgery judging function received by said first receiving means if the color image data is generated by the image generating apparatus having the forgery judging function, and controls formation of the color image according to a result of judgment by said judging means if the color image data is generated by the image generating apparatus not having the forgery judging function.
