Abstract: An image processing method includes the steps of converting input image data to ink color data corresponding to each amount of a plurality of colors of achromatic inks used for printing, and generating printing data for first, second and third achromatic inks based on the ink color data. The printing data is used for printing by causing a printing head to scan a common image area in a printing medium a plurality of times, the printing head ejecting the plurality of colors of inks. The converting step converts the input image data to ink color data for the first, second and third achromatic inks so that the first achromatic ink is used with respect to a value of the input image data indicating achromatic color, and the generating step generates the printing data for the first, second and third achromatic inks so as to (a) make a printing duty for the first achromatic ink during first half of the plurality of scans higher than a printing duty for the first achromatic ink during the latter half of the plurality of scans, and (b) make printing duties for the second and third achromatic inks during the latter half of the scans higher than in the first half of the scans.

Abstract: While a conveying error of a roller depends on the eccentricity of the roller, the amount and the state of the eccentricity sometimes makes the roller have different conveying errors from one point in the longitudinal direction of the roller to another. There is provided a construction for obtaining a correction value that is suitable for the correction of the conveying error even in such a case as described above. To this end, plural test patterns are formed in the longitudinal direction of the roller. Then, a suitable correction value for correcting the conveying error that depends on the eccentricity of the roller is obtained on the basis of these test patterns.

Abstract: An image reading apparatus that, in a case where the light amount of light illuminated from an image reading lamp has decreased, maintains the quality of a read image without decreasing productivity, and a method for controlling that image reading apparatus, are provided. To accomplish this, this image reading apparatus is provided with RGB line sensors that read a color image, and a monochrome line sensor that reads a monochrome image and has a faster horizontal transfer speed than the RGB line sensors. Further, this image reading apparatus reads a monochrome image using the RGB line sensors even in a monochrome mode in a case where the light amount of the lamp for illuminating an original decreases and so an output level for reading an image with good quality cannot be obtained from the monochrome line sensor.

Abstract: In an ink jet printing apparatus using many types of inks to execute bidirectional printing, when symmetrically arranged ejection opening rows for a cyan, magenta, and yellow inks are used in the print head, one-pass bidirectional printing is executed. On the other hand, if ejection opening rows for a black ink are used in addition to the above ejection opening rows, multi-pass printing is executed so that there are a number of dots formed with one application order for the black and other color inks and the same number of dots formed with another application order for the black and other color inks. This reduces the non-uniformity of the colors attributed to the difference in application order.
