    Abstract: In a watermark process section in an image processing apparatus, a visible watermark pattern read-out section reads out a visible watermark pattern that is stored in a memory. An invisible watermark generating section draws an invisible watermark on the read-out visible watermark pattern. Image data, which includes both the visible watermark and drawn invisible watermark, is multiplied by an overlay ratio. An adder section adds the visible/invisible watermark image data, which is multiplied by the overlay ratio, and input image data. Thus, watermark-overlaid image data is generated.

    Abstract: An image processing apparatus and an image processing method of the present invention improves image quality during monochrome output by adaptively executional conversion from a color image signal to a monochrome image signal during monochrome image output, and by using outputs from color and monochrome sensors at the same time. Moreover, it lowers the cost of compressing a color signal by using a color sensor with a lower resolution than that of the monochrome sensor.

    Abstract: When a first mode is designated, an RGB image signal obtained by reading an image is compressed, decoded and stored. After that, the resultant signal is converted into a CMYK image signal on the basis of a first color conversion system, and an image based on the YMCK image signal is formed on a medium. When a second mode different from the first mode is designated, an RGB image signal obtained by reading an image is directly converted into a CMYK image signal on the basis of a second color conversion system, and an image based on the YMCK image signal is formed on a medium.

    Abstract: A lower-bit replacement means of an information addition means replaces lower 3 bits of an 8-bit image signal with 3 bits of an image area separation signal, and outputs an 8-bit conversion image signal. A lower-bit extraction means of an information extraction means extracts lower 3 bits of the 8-bit conversion image signal and outputs an image area separation signal as additional information. On the other hand, as regards image information, the conversion image signal input to the information extraction means is output as it is, as an image signal.
