摘要： An image processing method is disclosed for performing an under color removal process and a black recording liquid incorporation process on an input three-color signal, and generating image data for an imaging apparatus that is configured to form a color image on a recording medium using recording liquids of cyan, magenta, yellow, and black. The method includes the steps of regulating a maximum black recording liquid incorporation amount such that glossiness of black realized in an image formed on a glossy recording medium is not degraded, setting the black to be realized by the black recording liquid until reaching the regulated maximum black recording liquid incorporation amount, and setting the black to be realized through addition of a composite of the cyan, magenta, and yellow recording liquids if the black to be realized requires an amount of the black recording liquid exceeding the regulated maximum black recording liquid incorporation amount.

摘要： Print head for black material is arranged such that the black material is to be ejected later than cyan, magenta, and yellow materials on both of forward and backward strokes, and the print heads for the cyan, magenta, and yellow materials are arranged in tandem in a main-scanning direction. The first processing unit converts input image data into CMY image data and then performs black generation and undercolor removal on the CMY image data, to obtain CMYK image data. The second processing unit converts CMY image data excluding K image data from the CMYK image data into image data for use in printing in the backward direction. The on/off switching unit switches between causing and not causing the second processing unit to covert the CMY image data depending on which one of printing in the forward stroke and printing in the backward stroke is to be performed.

摘要： An image processing apparatus, which performs an error diffusion on M-value image data with an error weight matrix into N-value image data, includes: a corrected-value calculating unit that calculates a corrected value by adding a first value and a second value to a pixel value corresponding to a processing-target color component of a pixel of interest, the first value being obtained by multiplying an error for each quantized pixel of the processing-target color component by the matrix, and the second value being obtained by multiplying an error for each quantized pixel of a different color component by the matrix; a quantizing unit that compares the corrected value with a quantization threshold, and outputs N-value image data; and an error diffusion unit that calculates an error at the pixel of interest by subtracting a quantization threshold from a value obtained by adding the first value to the pixel value.
