摘要： A color image processing device is disclosed which has an increased degree of freedom in black-coloring processing and permits color images which have good color reproducibility and are less susceptible to position displacement in black-colored portions to be output. The device includes a minimum detector circuit, a first lookup table for determining the amount of black material (K), a second lookup table for determining the amount of black material (k1) in color materials which has one of 256 values from 0 to 255, a third lookup table for determining the amount by which the underlying color is removed (k2) which has one of 256 values from 0 to 255, and three subtracters and three dividers for processing the outputs of the lookup tables to calculate C′, M′ and Y′ indicating the amounts of color materials used in the printer. The amount of black material and the amount of black material mixed with each of C, M and Y are controlled according to the relations: K=&agr;×min(C, M, Y) C′=(C−k1)/(255−k2) M′=(M−k1)/(255−k2)and Y′=(Y−k1)/(255−k2) where &agr; is a black rate of up to 100%.

摘要： 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.

摘要： 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.

摘要： There is disclosed an image processing apparatus for generating an address based on a difference (MAX−MIN) between a maximum value MAX and a minimum value MIN among signals CMY indicating three primary colors of a color image for each pixel, and generating a black ink signal based on data read from a lookup table in which the data is read from the generated address, so that a black ink strength is independently set with respect to density and chroma of the image. Moreover, the lookup table with the black ink signal and an undercolor signal stored therein has a storage capacity of a number obtained by totaling a number at which the difference (MAX−MIN) between the maximum value MAX and the minimum value MIN is an integral multiple of a predetermined value and a number at which the difference is other than the integral multiple and the maximum value MAX is equal to a maximum value of a defined region. Thereby, all combinations of the maximum value MAX and minimum value MIN are linearly interpolated without disposing any storage region.

摘要： 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.
