    摘要: In an ink amount limiting section 4, there are obtained ink amount limiting coefficients which are used to limit the ink amounts of the respective colors in such a manner that, where the maximum number of times of repeated printing with respect to a unit pixel that can prevent the ink from being blurred and from soaking up to the back surface of the record medium is set for a given value, the maximum number of times of ordinarily repeated printing within the unit pixel can provide a limited repeated printing conversion number equal to or less than the above-set given value. And, based on the thus obtained ink amount limiting coefficients and the image signals of the respective colors output from the &ggr; correcting section 3, print signals are generated and output. The print signals are quantized into the number of times of repeated printing in the halftoning section 5 according to a multi-level error diffusion method, and the thus quantized print signals are dot printed repeatedly in the printing section 6 to thereby form an image. In the print signals that are output from the ink amount limiting section 4, since the number of times of repeating ink drops is limited to the given value or less, the number of times of repeated dot printing by the printing section 6 is substantially equal to or less than the given number of times, thereby being able to reduce the possibility that the ink can be blurred and can soak up to the back surface of the record medium.

    摘要: In an image processing apparatus, a first conversion unit converts, on the basis of an input device profile, input data into first device-independent data expressed by a color space that is independent of an apparatus. A storage unit stores plural conversion profiles for converting using a color appearance model in the color space that is independent of the apparatus in correspondence with plural device characteristics that are dependent on apparatuses. A selection unit selects a conversion profile corresponding to characteristics of the input device, characteristics of an output device, observation conditions of the input data and the output data. A second conversion unit converts, on basis of the selected conversion profile, the first device-independent data into second device-independent data. A third conversion unit converts the second device-independent data into the output data on the basis of an output device profile.
