Apparatus with image reading units arranged in zigzag manner for obtaining digital data to generate one-line image data

摘要

In a color reading apparatus for successively reading respective red, green, and blue colors in each line while a document is continuously conveyed to a plurality of line sensor units arranged in a zigzag manner, the line sensor units are arranged with a distance equal to or shorter than a unit of line to prevent a color shift. When read data of the plurality of line sensor units in a conveying direction are to be combined, image data shifted by the number of lines corresponding to distances between the line sensor units in the conveying direction are set as first combination candidates. A color code and a line code are added to each of the data. Image data having the same color code and the same line code are combined. According to the image reading apparatus structured as described above, it is possible to obtain data capable of reproducing read data for each color on the same line without errors.
