1. An image processing apparatus comprising:
- development means for developing coded data into image data by analyzing the coded data and, at the same time, creating positional information within one display area of said image data;
discrimination means for discriminating an image area to embed specific information therein in accordance with the positional information created by said development means at the time of development;
means for embedding the specific information in the image area discriminated by said discrimination means in a manner that makes it difficult for humans eyes to discriminate the presence of the specific information; and
determination means for determining the size of the developed image data, said embedding means being arranged, in accordance with the result of the determination by said determination means, not to embed to specific information.

Abstract
An image processing method comprises the steps of developing coded data into image data by analyzing them, at the same time, creating the positional information within one display of the image data, discriminating the area to embed a pattern that indicates a specific addition information therein in accordance with the kind of image data and the positional information created in the development step at the time of development, and embedding the information hardly discriminately by eye-sight in the area discriminated in the discrimination step.

7. A image processing method comprising the following steps of:
-
developing coded data into image data by analyzing the coded data and, at the same time, creating positional information within one display area of said image data;
discriminating an image area to embed specific information therein in accordance with the positional information created in said developing step at the time of development;
embedding the specific information in the image area discriminated in said discriminating step in a manner that makes it difficult for human eyes to discriminate the presence of the specific information; and
determining the size of the developed image data, wherein said embedding step, in accordance with the result of the determination in said determining step, does not embed the specific information. - View Dependent Claims (8, 9, 10, 11, 12)

13. An image processing method comprising the following steps of:
-
converting given coded information into image data;
embedding specific information in the image data when the coded information does not indicate a character, irrespective of the density of said image information; and
determining the size of the converted image data, wherein said embedding step, in accordance with the result of the determination in said determining step, does not embed the specific information. - View Dependent Claims (14, 15, 16)

17. An image processing apparatus comprising:
-
creating means for creating image data;
determination means to detect the size of the image shown by the image data created by said creating means, and to determine the size of a unit pattern indicating specific additional information in accordance with the detected size of the image; and
adding means to add the unit pattern of the size determined by said determination means to the image shown by said image data in a manner that makes it difficult for human eyes to discriminate the unit pattern.
