Abstract:
1. An image reading apparatus including a plurality of image reading units arranged in a zigzag manner and each configured to undergo a reading operation to read a document continuously conveyed to obtain digital data by reading reflection light for each color on the document by photoelectric conversion elements arranged in line while light sources having a plurality of colors are successively turned on and off, the image reading apparatus comprising: first image detecting means for detecting the digital data at mutually asynchronous read timings of the respective image reading units, each detected digital data including color data having at least three values corresponding to three colors of red, green and blue and indicating a predetermined one of the colors of the light sources and including read period data indicating a predetermined one of capture periods of the digital data; an image memory including a plurality of addresses for storing in storage regions designated by the respective addresses the digital data obtained during a reading operation by each of the image reading units and detected by the first image detecting means; and image control means for combining the digital data associated with the respective image reading units and stored in the storage regions of the image memory to generate one-line image data.
