摘要： This invention is directed to a method capable of performing satisfactory image reading by absorbing variations in each apparatus. According to this method, in primary color reading, light emitting unit sequentially irradiates an image original with light components of three primary colors and reads the image original, and in complementary color reading, the light emitting unit simultaneously irradiates the image original with one of three different color combinations, which includes two of the light components of three primary colors, and reads the image original. Each of the primary and complementary color readings includes image processing of executing shading correction of image data based on calibration data obtained by calibrating the light emitting unit when reading the image original.

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 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 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.
摘要翻译：当使用渐变掩模来分配由重叠头部中的重叠部分记录的图像数据时，由于由组装误差引起的冲击位置的位移，在由重叠部分记录的图像中产生颜色不均匀。结果，不能执行由重叠部分记录的贴片的精确比色测量。为了解决这种问题，与正常记录图像时相比，当记录用于执行颜色校正的测试图案时，将图像数据分配给重叠部分的分配比设置为近似恒定。
