摘要： An image processing apparatus having a simple structure capable of forming high quality images. The image processing apparatus includes a document reader for generating a first luminance signal for each pixel in a color multi-valued image; a factor multiplication part for multiplying the first luminance signal by a factor to obtain a second luminance signal; a pixel-attribute determination part for determining the color attribute of a noticed pixel based on the second luminance signal; and a main controller. The main controller is configured to count an array attribute determined by an array of the color attributes for 32 lines in a block obtained by dividing a band including 64 lines in the color multi-valued image into eight in the main scanning direction, calculate image-characteristic parameters for the block based on the counted values, determine a block image attribute from the counted values and the calculated parameters, and determine the image attribute of the band based on the determination result.

摘要： In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

摘要： This invention is directed to an image reading apparatus. In the apparatus, reading an original by irradiating it with light of three primary colors, respectively, and by receiving the reflected light is performed as follows. More specifically, an operation mode is designated, and conditions used to perform image reading are set in accordance with the designated mode. Under the set conditions, the image reading is performed according to a method of irradiating an original sequentially with beams of the three primary colors and reading the beams reflected by the original. Alternatively, under the set conditions, image reading is performed according to a method of irradiating an original simultaneously with beams of two primary colors in each of three different combinations of the three primary colors and reading the beams reflected by the original. Instead, image reading is executed twice according to these two methods.

摘要： In the present invention, joint sections and non-joint sections are formed in nozzle arrays of a plurality of chips arranged in a print head. Correction values for correcting input image data are calculated for reducing color difference caused by variation in the ejection characteristics of the nozzles. In this calculation of correction values, first a first correction value corresponding to first nozzles that form a color measurement area is calculated based on the color measurement value obtained by measuring the color of a discrete color measurement area included in a patch formed by a nozzle array. Next, a second correction value for correcting input image data corresponding to second nozzles of the nozzle array is calculated based on the first correction value. Different complementary processing is used when calculating the second correction value corresponding to a non-joint section, and when calculating the second correction value corresponding to a joint section.

摘要： In ink-jet printing apparatuses having a monochrome head which is longer than a color head, if a monochrome image is processed as a color image, the printing speed cannot be improved. Accordingly, the color attribute is determined by pixel based on a luminance signal indicating a color multivalue image, and the number of color attributes and the number of array attributes in a first line group are counted. Based on these count values, a parameter indicating an image characteristic of second line group including the first line group is calculated. The image attribute of the second line group is determined in correspondence with the respective count values and the parameter. Then, based on the results of determination about adjacent second line groups, the image attribute of third line group included in the second line groups is determined. Thus attribute determination can be appropriately performed in predetermined band units of image data.

摘要： When printing an image using a plurality of inks, color unevenness caused by variations in ejection characteristics among nozzles is corrected at suitable timings in accordance with change in the color unevenness over time, and favorable image output without noticeably color unevenness is maintained. For this purpose, parameters are prepared, for colors formed by combinations of at least two colors of ink, the parameters being determined so as to reduce differences in coloration on a print medium caused by individual variations in the ejection characteristics of a plurality of nozzles. When printing, a first color signal included in individual pixels is corrected for a second color signal by using the parameters. Information regarding the ejection volume characteristics of a plurality of nozzles is acquired as appropriate, and by estimating changes in coloration from this information, suitable timings for overwriting such parameters are determined.

摘要： When a gradation mask is used to distribute image data to be recorded by overlapping portions in an overlapping head, color unevenness is generated in an image recorded by the overlapping portions due to a displacement in impact positions caused by an assembly error. As a result, accurate colorimetric measurement of patches recorded by the overlapping portion cannot be performed. To solve such a problem, a distribution ratio by which the image data is distributed to the overlapping portions is set to be approximately constant when recording a test pattern for performing color correction, as compared to when normally recording the image.
