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： 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.

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： This invention is directed to a method capable of performing appropriate under color removal in image original reading. According to this method, under color removal of the original is performed as follows. A printing medium without any printed image is read by primary and complementary color readings. A brightness signal distribution is generated by converting, using a provisional table, each of image data generated by the reading methods. The lowest one of signal levels is selected from each of the distributions. In correspondence with each of the primary and complementary color readings, a conversion table is formed, which converts the image data to make a pixel value corresponding to the selected lowest one of the signal levels to a value representing white. Under color removal of the image data is performed using a corresponding conversion table in accordance with the reading method of the image original.

摘要： This invention is directed to provide a method capable of performing filter processing suitable for each of different image reading methods. This method includes the steps of causing a light emitting unit to sequentially irradiate an image original with light components of three primary colors and read the image original, and causing the light emitting unit to simultaneously irradiate the image original with one of three different color combinations, which includes two of the light components of three primary colors, and read the image original. The method further includes the step of processing image data obtained based on the reflected light received by the light receiving unit after changing a filter to be used for image processing depending on whether reading of the image original is primary color reading or complementary color reading.
