PROBLEM TO BE SOLVED: To provide a color image reader that can deal with various reading resolutions, the image sizes of originals and line gaps and to provide a memory controller that is used for this color image reader to control a correction memory. SOLUTION: The color image reader that uses a correction memory to apply line gap correction to RGB digital signals corresponding to an image of an original read by a 3-line image sensor and provides an output employs the memory controller that controls the write of the RGB digital signals to the correction memory and the read of the RGB digital signals from the correction memory. The memory controller controls the correction memory so as to write the RGB digital signals at the same pixel positions of the same line concerning the RGB digital signals at the same pixel positions on lines with a prescribed line interval and supplied at the same time to consecutive memory addresses, thereby solving the task above.
