Abstract
Control for adding additional information to an input image is efficiently done in correspondence with the recording sheet used without any sensors for detecting the type of recording sheet. To achieve this object, according to this invention, whether or not the additional information is to be added to input image data to be hardly identified by the human eye is controlled in accordance with the type of image formation process. Alternatively, a method of adding the additional information to input image data to be hardly identified by the human eye is controlled in accordance with the image processing mode corresponding to the recording sheet.
Claims15
An image processing apparatus, which selectively uses a plurality of image processing modes suitable for different types of recording sheets, comprising:
- adding means for determining in accordance with the image processing mode used by said image processing apparatus to process input image data whether or not additional information is to be added to the input image data to be hardly identified by a human eye, and executing the addition in accordance with a determination result;
- and
- output means for outputting image data to which the additional information is added by said adding means to image forming means.
An image processing method, which selectively uses a plurality of image processing modes suitable for different types of recording sheets, comprising:
- an adding step of determining in accordance with the image processing mode used by said image processing apparatus to process input image data whether or not additional information is to be added to the input image data to be hardly identified by a human eye, and executing the addition in accordance with a determination result;
- and
- an output step of outputting image data to which the additional information is added in said adding step to image forming means.
A program for controlling an image processing apparatus, which selectively uses a plurality of image processing modes suitable for different types of recording sheets, comprising:
- an adding step of determining in accordance with the image processing mode used by said image processing apparatus to process input image data whether or not additional information is to be added to the input image data to be hardly identified by a human eye, and executing the addition in accordance with a determination result;
- and
- an output step of outputting image data to which the additional information is added in said adding step to image forming means.
