<P>PROBLEM TO BE SOLVED: To provide an image-reading device, an image reading method, and a program which correct suitably a color shift in a sub-scanning direction of read signals read by a plurality of line sensors without causing increasing of a circuit scale and processing time. <P>SOLUTION: The image-reading device makes a read signal from one line sensor be a reference signal among a plurality of read signals output from a plurality of line sensors in order to align a line position of a read signal of each color by correcting a position deviation in a sub-scanning direction among line sensors, and detects a correlation between the reference signal and each of a plurality of read signals from other line sensors in a plurality of lines shifted for every prescribed line unit from the line where the reference signal is read, and selects a read signal of a line where the correlation is high as the read signal of the same line as the line of the reference signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
