摘要： An image processing apparatus is provided with an input circuit for inputting a plurality of multilevel signals, each corresponding to a respective one of a plurality of pixels. An emphasizing circuit emphasizes a high frequency component of one of the multilevel image signals by using the multilevel image signals of a plurality of pixels and outputs the emphasized multilevel image signal. A discriminator discriminates a dot area of an image represented by the one multilevel signal input by the input circuit, by using the multilevel image signals of the plurality of pixels whose high frequency component is emphasized by the emphasizing circuit. The number of pixels used by the discriminator is larger than the number of pixels used by the emphasizing circuit.

摘要： Interpolation processing is applied to the output of a look-up table in which a correlation between color-separation signals and density signals ideal for these color-separation signals are stored, with a quantization error produced when quantizing the color-separation signals being adopted as an interpolation coefficient. The quantization and the interpolation processing are executed in a uniform color space.

摘要： An image conversion apparatus for image-converting input color image signals, and outputting the converted signals to an output apparatus, allows execution of a plurality of different color processing operations, checks if an input color image falls within a color reproduction region of the output apparatus, and changes the color conversion processing result to be output depending on whether or not the input color image falls within the color reproduction region of the output apparatus. For example, when the input color image falls within the color reproduction region of the output apparatus, color reproduction color-matched with input color image signals is performed. When the input color image falls outside the reproduction region, color reproduction is performed by color conversion processing assuring highest color reproducibility.
