An image processing apparatus includes a generator, a storage, an image data format converter, and a sender. The generator generates print image data for printing an image, based on image data sent from an external device. The storage stores the print image data. The image data format converter converts the print image data into image data in a format handled by an external device. The sender sends the converted image data via an IP (internet protocol) network to the external device. The image data format converter performs one of color space conversion, expansion, compression, resolution conversion, filtering, halftone processing, density gamma conversion, and noise removal in accordance with parameters determined based on at least one of property information of the print image data and property information requested by the external device.

In an apparatus for embedding an electronic watermark, a determining unit determines whether a specified area that is specified is present in image data. A text/non-text detecting unit detects a text area and a non-text area in the image. The specified area is at least one of the text area and the non-text area as an area. The embedding unit embeds an electronic watermark into the specified area.
